ZETADYN 1DV System Information - Summary
1.1
Applications
ZETADYN 1DV controllers are designed for up to 33 KW drives (motor rated current 90A) where high positioning accuracy is required. They are mainly used in • Passenger and goods lifts • High-bay storage and retrieval systems • Cranes and material handling plants. ZIEHL-ABEGG supplies complete AC drives with asynchronous motors, digital encoders and ZETADYN 1DV controllers.
1.2
Functions and features
A microprocessor controls the drive in accordance with the time and distance related programs selected by main control system. Fully digital 4-quadrant motor speed control is accomplished by lowering the voltage at constant frequency. The whole drive cycle is controlled from start to stop. Features of the digital ZIEHL-ABEGG drive control system: • accurate control response with good dynamics and a high positioning accuracy • simple to commission and operate • comprehensive diagnostic system and data protection functions • high level of safety achieved by multiple monitoring systems • in case of maintenance, replacement of the device without new adjustment of the control device

The logic design allows the equipment to be easily adapted to various applications.
1. Controls The superior control system communicates with the controller through floating inputs and outputs. Time and distance related control programs are selected by activating optically coupled inputs. The operating condition of the drive is continually signalled back to the controls through floating relay outputs.
ZIEHL-ABEGG asynchronous motors for variable drives have two electrically separated windings. The AC winding produces the drive torque and the DC winding the braking torque. M

2. Parameterizing Commissioning, service and documentation are supported by digital computer technique: speeds, accelerations and other parameters specific to the system can be entered through text dialogue by using the integral display and operating unit. A password protects the system against misadjustments. It is also possible to parameterize through a PC or the ZETAMON software with user guide, which is available as one of the accessories.

Requirements
Ziehl-Abegg provides you with an optimally tuned D.C. drive with asynchronous motor, digital speed transmitter and controller ZETADYN 1DV. If you only purchase the controller - for example when retrofitting an old installation - please observe the following.
Motorselection:
Installation of a encoder:
Suitable devices are all pole-changing elevator motors having a pole ratio of 4/16.
Provided that no sleeve shaft encoder (e.g. Ziehl-Abegg -ET3R-1024) can be installed, there are three possibilities:
Pole pair ratios of 4/24 and 6/24 are partly suitable. For these motors, the course of the characteristic line for the d.c. injection brake (low-speed winding) in the range of speed 0 is a bit more unfavourable and there can be a small stopping jerk in the direction "EMPTY UP".
1.
Installation of a encoder linked to the motor shaft by means of a toothed belt. Documentation: LEM6.06.385 and LEM6.06.815. "Installation of an encoder G58H-1024"
Additional balance weights are to be removed, if necessary. An existing massive handwheel should be exchanged against a plastic handwheel. Besides the energy saving, additional reserves are liberated for the speed regulation.
2.
In case of gauges provided for the installation of an analog tacho with Euroflange, it is possible to use an incremental encoder of the same construction G71-xx/30. The tacho can be supplied with a shaft diameter (XX) of 07 and 11 mm.
Prior to the retrofitting (projecting phase) it is necessary to check whether the motor works properly in the pole-changing areas in all operating states. The motor as well as the gear have to work calm, i.e. without out-of-balance and clearance. Mechanical weaknesses cannot be improved by a control but can possibly make a controlled operation impossible.
3.
It is also possible to install an incremental encoder direct to same gears.
Controllerselection: The rated current of the controller has to be higher or equal to the rated current of the highspeed motor winding.
8
System information ZETADYN 1DV
Note: In case of own constructions, you have to pay attention to the fact that the encoder is mounted to the motor (gear) without any clearance, without any axial offset and solid as to the mechanical link. Preferably you have to choose an encoder with a resolution of 1024 increments/track. ZIEHL-ABEGG can be asked for documentation concerning the connection possibilities of encoders of external manufacturers.

Control and controller functions
The functional equipment of the controller ZETADYN 1DV makes it possible to adapt to the various applications. In the following, we give a short description of the factory presetting. 3.1 gives a general description of the control of the controller. 3.2 gives a detailed description of specific functions of the device.
Table: factory presetting Normal running mode: Run at high running speed "V3" and positioning run at "V1" Run at intermediate speed "V2" and positioning run at "V1" In both cases, the decelerating distance is driven depending on the path, i.e. when the driving command "V3" or "V2" respectively is switched off, it is always the same decelerating distance that is travelled independent from the actual speed achieved at the moment (arch travel). Readjustment: Readjustment possibility with speed "VZ". Manual and service operation: In addition, three speeds "V_ZE1", "V_ZE2" and "V_ZE3" are available which are not regulated depending on the path.
Output: Controller active - "RB" With the output "RB" the control device switches the main contactor to the currentless state. Output: Mechanical brake - "MB" With the output "MB" the control device switches the mechanical stopping brake.
Monitoring functions: Checking the input speed (0.3m/s) by means of output "SK1". Checking of the maximum speed by means of output "SK2". Checking of the motor temperature by means of output "SK3". Fault message: The control device indicates a fault at the output "ST". The following functions are monitored: - power outage - cyclic change - heat sink excess temperature - motor temperature - encoder breakage - start-up monitoring - parameterization - deceleration monitoring Additional functions: The inputs "ZE1", "ZE2" and "ZE3" as well as the outputs "SK1", "SK2" and "SK3" can be programmed with special functions in another way than in the factory setting. Examples:
Changing over between two completely separated parameter sets. Switching off the forced air cooling of the motor with the function of the after-running timerelay. • Switch output for the monitoring of a freely adjustable speed limit. • •

(1) The higher control sets the direction of motion for the inputs "RV1/RV2" and triggers the inputs for the running speed (in this case "V1" and "V3"). The "controller release -RF" can already be fed. It is also possible to connect it only when the direction and the speed are fed. By means of the output "Controller active RB" the control device indicates that the input signals have been accepted and that it is ready for a new run. When switching "RB" the main contactor K0 has to be closed. When switching the output "Mechanical brake -MB" the control of the brake has to open immediately and without delay.
(2) The drive accelerates until the preset speed is reached. (3) A travel at a constant speed follows, until the activation of the travel speed ("V3") is cancelled. (4) The drive decelerates to the positioning speed "V_1". (5) After a short distance covered, the positioning speed is switched off. (6) The drive continues to decelerate. (7) The control device disconnects the output "MB". The control is to close the brake without delay. (8) The main contactor "K0" has to be switched on until the contactor "RB" is switched off.
The spring-loaded safety brake is to be switched on and off by means of the relay "MB". This is the only guarantee that the control device is able to control start-up and stopping without jerk. The main contactor "K0" is to be switched on and off by means of the relay "RB". This is the only guarantee that the main contactor is switched in the currentless state and enables startup and stopping without jerk. In case of trouble, i.e. when the relay "ST" is released, the control has to make sure that the mechanical brake and the main contactor are immediately switched off.

Description of controller functions
3.2.1 Switching on and off The controller switches itself on when the main voltage is applied to the controller circuit board. All three mains phases must be switched on simultaneously. The output relay trouble "ST" switches automatically on about 1 sec after the control device has been switched on. Until now, the state of the control inputs is ignored by the controller.
When the supply voltage of the controller board is switched off, all relay outputs open without delay. The higher control has to close the springloaded safety brake and open the main contactor "K0". The control device blocks the power semiconductors. If the controller is switched off during running, the drive is decelerated because of the braking torque of the spring -loaded safety brake.

3.2.2 Start and ac celeration (1) The main control system activates the inputs "Speeds - V_" together with one "Direction Preset - RV_". The controller closes the output relay "Controller ready RB" and the relay "Spring-loaded safety brake - MB".
(2) The main control system opens the springloaded safety brake. The controller accelerates up to the maximum activated speed in accordance with the set acceleration with rounded transitions.

3.2.3 Distance-controlled deceleration - Arch travel In case of decelerating runs, the path dependent deceleration is carried out by the driving commands V3 and V2 according to the positioning speed V1. To do this, the parameter /INSTALLATION/ S_ABH has to be ON (factory setting). In case of all other change-overs between speed presettings the running curve is carried out depending on the time.
times (see illustration 3.4), independent from the speed achieved at the decelerating point (4). Functioning: If the final speed set (Figure 3.4) has not yet been reached at the decelerating point (4), the drive continues to accelerate. The control device determines the point X from which the deceleration has to be initiated in order to reach the stop with the positioning speed V1. Now the control device rounds out the running curve and decelerates by means of the deceleration A_NEG set.
Advantages: The path dependent deceleration offers advantages if the final speed (V3 resp. V2) cannot be achieved in case of runs between stops that are close together. In such a case, the control device carries out an arch travel. The control device provides for continuous rat runs and the shortest possible cycle
Because of that, in case of the ARCH TRAVEL and the NORMAL TRAVEL, the decelerating distances S_31(4 -> 5) and the rat runs s_1 (5 ->6) are the same.

Control: The control has to feed the driving command V1 prior to the removal of the driving command V3 (resp. V2). Side-effects: In case of controls showing a signal running time of more than 10 ms, it islonger possible the rat for ARCH travel is no thethat same as run for NORMAL travel. In addition there is a small error with the total decelerating distances measured (S_30, S_20). The controller is able to compensate this error in case of an almost constant signal operation time. To do this, the signal operation time has to be entered in /INSTALLATION/T_SIG at commissioning.

After switching off the current speed setting, the control device decelerates depending on the time up to the highest speed still controlled and according to the deceleration set with rounded out transfers.

3.2.5 Distance-corrected deceleration of "V3", "V2" and "V1" The control device is able to delay the switching off of the running signals by a distance set. It is possible to delay "V3" by the path "S_DI3",. "V2" by the path "S_DI2" and "V1" by the path "S_DI1" and then switch it off.
ADVANTAGE: In the shaft, the disconnecting tag of "V3" is set as far as possible from the flush "V1". After the desired running curve is available, the remaining rat run is eliminated by introducing this value in parameter S_DI3. Furthermore, it is possible to correct the disconnecting tag for the flush "V1" by means of S_DI1.

The controller decelerates down to a standstill in accordance with the set deceleration /DECELERATING/A_NEG with rounded transitions. When the speed drops below the /DECELERATING/V_BR speed, the controller opens the output relay "Spring-loaded safety
brake - MB" so that the spring-loaded safety brake engages at the same moment as that at which the speed 0 is reached. The controller blocks the power semi-conductors and closes the output relay "Controller ready - RB".

If the value 3.5 m/s2 is set for A_MAX (factory setting), the control device imm ediately switches off the output "MB" and "RB". In this case, the drive is only decelerated by means of the mechanical stopping brake.

3.2.8 Readjustment For the readjustment of the correction of the elongation of a rope when discharging the cabin, the driving command "V_Z" is triggered. For safety reasons, the control device ignores all other speed settings when triggering the input "V_Z". Unlike the normal positioning process
(normal stop), the mechanical brake "MB" engages without delay. In order to avoid oscillations, the control should wait a certain time until the rope is put at rest again.

3.2.10 Short travel Use: The SHORT TRAVEL program offers advantages if the final speed (V3 and V2) cannot be activated when travelling between two very close stopping points.
Control: (see figure 3.11). When triggering the controller release RF, the driving command V1, an additional input ZE3 and the direction set RV1/2, the drive is carrying out a distance S_KF set by the operator. The control device itself is optimizing the driving course by means of the acceleration and deceleration set. After having carried out the distance S_KF (1->5), the drive is running at the positioning speed V1. When reaching the flush switch (6), the running signals (V1, ZE3 and the direction set) are switched off.
Example: V3 is switched off 2 m before flush. V2 ist switched off 1 m before flush. But there is a floor distance of only 0.7 m. In this case, it is possible to use the short travel in order to carry out a run depending on the distance and using the optimum time possible.

3.2.11 Troubles The control device controls - the mains voltage (phase sequence, - outage) - the speed - the heat sink temperature - the encoder signals - the motor start-up - the motor direction - the motor temperature. The run program will be stopped if the controller identifies troubles. The controller blocks the power semi-conductors. The output relay "mechanical brake - MB" and "Fault - ST" are switching off immediately.
The main control system must close the springloaded safety brake and open the main contactor "K0". If an error occurs during running, the drive is delayed because of the braking torque of the spring-loaded safety brake. In order to acknowledge the error, the triggering of the controller release "RF" has to be stopped. After switching the controller release "RF" on again, the fault relay "ST" picks up again.

Exception: After mains phase outage, excess temperature of the heat sink or of the motor the output relay automatically picks up after the trouble has been eliminated when parameter /INTERFACES/QUIT is switched on (factory setting is OFF). Specific control device monitorings can be switched off in /ZA_INTERN/MASK1 to MASK3 (described in 4.3.11).

Control and controller functions
3.3 To ensure safe operation of the controller Basically, electronic equipment is not failure-proof. The user is responsible for ensuring that the drive is in a safe condition in the case of controller failure. It is essential to observe the following three instructions:
The spring-loaded safety brake must be operated without delay through the relay "MB". This is the only way to ensure smooth control actions from the controller. The main contactor "K0" has to be switched on and off without delay together with the relay "RB". This is the only guarantee that the main contactor is switched in the currentless state and enables start-up and stopping without jerk. In case of trouble, i.e. when the relay "ST" is released, the control has to make sure that the mechanical brake and the main contactor are immediately switched off.

Operation and settings
The user can easily adapt the controller to any particular job. The system can be commissioned and operated by either of the following two very simple methods: 1. Operation through the keyboard and the LCD display with simple text dialog.
The parameter menu structure is the same for both communication methods. The parameters set can be protected against unintentional or unauthorized change by means of a password (numbers ranging vom 1 to 9999).
2. Remote operation with a PC and the ZETAMON software available as an extra.

Parameters may only be changed when the drive is at a standstill.
Operating through keyboard and LCD display
LCD and the keyboard offer the operator the following direct facilities: - setting all the parameters required for commissioning - performing simple measuring and control operations and - recording the operating states. Programming is very simple, by means of the three push buttons. The parameters available are divided into menus according to whether they are belonging together. The selection of a menu is effected by means of the arrow keys (see figure 4.1). When pressing the key [P], you change to the parameters assigned to the menu. The selection of a parameter is effected by means of the arrow keys. When pressing the key [P], it is possible to change the parameter using the arrow keys.

It is possible to attenuate three error messages. To do this. the corresponding error number is to be put in.
T_GUE
If no speed transmitter signal appears within the time T_GUE, the control device switches to error and displays the error message "9 No starting" or "14 Encoder trop out". If the actual speed exceeds the value of the rated speed to the nominal speed by more than 50 % or if it falls below more than 50 %, the control device switches to trouble and displays the error message "36 N_PROG << N_REAL" resp. "35 N_PROG >> N_REAL". The control device stops the run in case of running without driving command but with triggered controller release "RF" after the time T_AUS. When the starting attenuation is switched on, the nominal value is kept in a tolerance range V_DM until the actual value follows. A smaller value for V_DM causes a smoother start-up. Determines the return-to-zero period in which the pre-braking torque M_VB returns to zero. Determines the return-to-zero period in which the starting torque M0 returns to zero. Determines the number of speed transmitter pulses attenuated by the rotation direction evaluation at start-up. Setting whether the positioning process (V1->0) is to be effected depending on the time or the distance. If HALT = t-Halt: Decelerating value for positioning process. If HALT = t-Halt: Rounding of V1 ->0 transfer. If HALT = s-Halt: Absolute positioning distance. Determines the time how long the after-braking torque is to be fed after closing the contact "MB".

Requirements
When commissioning the device locally, no measuring instruments are required. Before starting the commissioning, the following points have to be checked: 1. The control device is installed and connected according to this description. 2. The operation of the device and the adjustment possibilities are well-known. 3. The control of the device is executed and checked according to this description.
The drive may be put into operation only if these three conditions are fulfilled.
Commissioning can be carried out in accordance with the brief instructions supplied with the equipment. The control parameters must be adjusted to suit the installation before the first run. Observe all instructions contained on these pages. If the controller is of special design, refer to the supplementary instructions before starting the commissioning procedure.
Before moving off, always ensure that no persons or objects are in the way.

The control device is preset by the factory. In case an encoder with a resolution of 1024 pulses/revolution is connected, it is possible to immediately carry out a controlled drive. Experience has shown that changes are effected by third parties when the control device is installed in the control cabinet and when tests are carried out outside the location. This is why the following procedure is recommended.

Recommendation: The disconnecting tag should - if possible - be set to a larger length of the brake path than that determined in order to have free space for the optimization of the performance. Later on, it is possible to abstain from a possible subsequent shortening of the disconnecting tag in the shaft, as with the parameter /DECELERATE/S_DI3 it is possible to shift the disconnecting tag of the control device internally up to the distance S_DI3. In order to achieve a positioning run as short and equal as possible with "V1", the disconneting tags have to be set with an accuracy of +/- 1 cm.
Disconnecting tags for the positioning speed "V1"
The disconnecting tag for "V1" is to be set with an accuracy of +/- 1mm 5 cm before flush.
Disconnecting tags for the average running speed "V2"
If necessary: the disconnecting tags of for the driving command "V2" are set as far as possible from the flush. At first, you only have to check whether the required length of brake path s_21 (figure 5.3) is smaller or equal to the brake path available. If not, the speed "V2" is to be lowered in order to avoid an overrun at commissioning. In case of installations with readjustment, this has to be disconnected from the control at first in order to be able to work without being disturbed. Commissioning

Unlike the AUTO pre-assignment, the running curve can be changed by means of the parameters shown in figure 5.4. Reference if the decelerating distance has to be reduced: - Increase A_NEG or decrease R_NEG1 up to 40 %. - With elevators, leave R_NEG2 generally at 90 %. ? Arch travel in case of several different floor distances. Set R_POS2 to 90 % so that Recommendation: the control device generates an optimally rounded running curve even in the most unfavourable case.
? Balance weight If it is not possible to remove unnecessary balance weights when old installations are retrofitted, it can become necessary to set the
roundings R_POS2 and R_NEG as large as possible. ? Parameter /Controller/DYN The elevator has to work in the setting range of 70 to 100 %. In case of smaller values, the control is increasingly attenuated, i.e. that the reaction of the control is weaker and there can be noticeable standard tolerances at the speed transfers. If - in case of a setting of DYN = 70 % - the controller exit quickly travels with a constant high running speed in the larger range, have to check whether the motor speed is you correctly recorded by the control device. This is of particular importance if you do not use a high wave tacho. The mounting of the incremental speed transmitter has to be effected without clearance and vibration. Possible mechanical defects (e.g. squeezing of a guide shoe) can influence the control in the same way.
Optimization of the positioning distance S_1 - Select parameter /Distances & Times/S_1. - Check whether the rat runs are almost equal on all floors. - With the parameter /DECELERATING/S_DI3 it is possible to shift the disconnecting tag until the rat run is about 5 cm.
Flush setting If the elevator cabin comes to a halt on all floors with the same distance to flush, it is possible to shift the disconnecting tag by means of the parameter /DECELERATING/S_D1. If the distance is not the same, the correction has to be made directly in the shaft.
Setting of the average speed V2 In case of installations where the average speed is used, V2 is increased as far as the rat run is equal to that achieved when the high speed V3 is decelerated. There is also the possibility to disconnect the disconnecting tag for V2 by using the distance /DECELERATING/S_DI2.
Optimization of the start-up reaction A final optimization assumes that the state of the rail guidance, the gear oil level, the cabin suspension etc. are in order. The start-up reaction is determined by the parameters T_VB, M_VB and M0 in menu "ACCELERATING". The procedure depends on the existing type of installation (/INSTALLATION/ANL).

Elevator •
Elevator with a good installation efficiency, i.e. when the cabin is empty and the brake is manually opened, the cabin automatically moves up. T_VB = 100 ms M_VB = 0% M_0 = 0% Test runs EMPTY UP: Increase M_VB setting until the cabin starts moving smoothly. Test run EMPTY DOWN: Increase M_0 setting until motor only slightly turns back when started. If the brake is not already open, T_VB should be increased (in steps of 50 ms).
•
Lifting gear First of all check whether the drive moves upward if RV1 is triggered. If not, exchange the connection of RV1 and RV2 and change the direction of the motor /INSTALLATION/MO_DR. Running trials UP: - Increase MO setting until the motor shaft n o longer turns back. Running trials DOWN: - Increase M_VB setting until the lifting gear drives down without sagging.
Running gear
Elevator with a small installation efficiency, i.e. when the cabin is empty and the brake is manually opened, the cabin only moves when driving the handwheel.
In case of running gears, the start-up process is absolutely different from those of the other two installation types. When opening the brake, it is the driver winding that is set under current. The torque which is linearly driven increases until the initial breakaway torque is surmounted. When the motor starts moving, the installation switches to the regulated operation.
T_VB = 200 ms M_VB = 25% M_0 = 0%
T_VB = 100 ms M_VB = 30% M_0 = 0%
Test run EMPTY DOWN: In order to overcome an initial breakaway torque, increase M_0 setting until the drive starts without jerk.
M_0 is adjusted in a way that the drive runs without jerk.The bigger M0 is, the faster the change-over from the controlled to the regulated operation.
5.5 Final of setting up When the commissioning is finished, the current parameter setting has to be noted in the setting card (Appendix A10 or in the short description). The error list can be erased by means of the parameter /STATISTIC/STAT4. When third persons (caretaker) have access too, the input should be protected by means of a password (/OPERATING/PW_N see 4.3.8).

Because of the digital construciton of the control device, numerous possible causes of trouble are already displayed as clear text. In general, it is possible to find the cause by means of these messages and by using the explanation given in appendix A4 as well as in the error search plan A5. The following procedure is recommended: a) If a trouble occurs (display blinks, error text and number are displayed), you have to look up the general error explanation in A4.
b) If no trouble is directly displayed by the control device, you have to check in the error storage /STATISTIC/STAT0 whether an error has occurred since the last maintenance has been carried out. The entry first displayed is the error that occurred last.

Conditions so that the control device is able to control start-up and stopping without jerk:
Is the spring-loaded safety brake switched on and off without delay by means of the relay "MB"? Is the main contactor "K0" switched on and off without delay by means of therelay "RB"? If the control does not evaluate the contact "RB": Is the main contactor switched on at the latest when the driving command is fed? Is the main contactor switched off time-delayed only when the brake comes in?

a) Motor turns up quickly to maximum speed and switches off -> Check the connection of the encoder (see A5.6). b) Motor does not move, motor noise can be heard ->Motor blocks? Speed transmitter signal (ET2/ET3) has broken down. - See A5.6 "Checking the encoder". Drive is not able to follow programed value. - check whether the correct encoder type has been set in /INSTALLATION/GEBER (bar number probably to high).
Speed encoder signal (ET2/ET3) has broken down. - See A5.6 "Checking the encoder". Drive does not decelerate: - Brake winding is probably not connected correctly. - /DECELERATING/A_MAX to high.
Drive switches to trouble when stopping
37 MTR still rotate
Motor still turns although the mechanical brake should have come in before long. Contact "MB" does not directly connect the mechanical brake.

Checking the encoder
Is the encoder connected in the way shown in the connection proposal A8? Should external encoders be connected, you have to check whether the technical data are met. Is the monitor connected in the right way?
Observe the real speed at the control device: /MONITOR/N_REAL Open the brake manually and observe the real speed.
If the control device does not register any speed: - Check the voltage of the transmitter supply: ET1 +15V
ET2 trackA
ET3 trackB
ET4 GND
ET5 -15V
In case of slow motor rotation (open brake manually for a short time), the voltage levels at terminal "ET2" resp. "ET3" have to change between + and -. - Current consumption in "ET2" and "ET3" typ. +7 mA /-1mA.
It is further possible to check the following two points by means of an oscilloscope or another multimeter of high-quality: - The pulse/pause ratio has to be 50 %. - The phases of track A and B are shifted by 90°.

Encoder ET 3R-1024 The ZIEHL-ABEGG encoder ET 3R-1024 is designed with a quill shaft for direct mounting on the controlled motor . The second motor shaft is still available. The encoder features contactless operation free of wear. The encoder connected to the controller ZETADYN 1DV produces two rectangular signals with 1024 pulses per revolution each at 24 Vss (centre zero). They are in phase quadrature. The encoder part produces a rectangular signal with 64 pulses per revolution electrically separated at 12 Vss. The signal is provided for monitoring devices (for example GU1). Description see data sheet ET 3R-1024, Connection see figure A8.
Encoder ET2R-1024 Hollow shaft encoder like the ET3R-1024, however with a closed case. An additional signal track for monitoring functions is not available. All encoders will be delivered with a 10m connecting cable. Encoder 58H-1024 We offer a retrofitting kit where an external encoder is driven by a V-belt (see 1.3 Requirements).
Encoder G71-xx30 This encoder is of the same construction as an analog tacho with Euro-flange (see 1.3 Requirements).

Changes and new functions
Control devices starting with themanufacturing number 3942xxxwith the software release 3.0 have the following differences compared with previous devices.
Changes:
•
When connecting the control device, itis no longer necessary to remove the front plate.
•
The current supply of the control unit board is also executed plugged-in.
•
The installation as well as the exchange of the control device has been simplified by means of constructional measures.
•
The freely programmable special outputs and the additional inputs have been preset as follows by the factory: "SK1"-Special contact 1 Contact K11-K12 is closed when the speed is higher than 0.3 m/s. "SK2"-Special contact 2 Contact K21-K22 is closed if the nominal speed is exceeded by 10 %. "SK3"-Special contact 3 Contact K34-K33 is open if the motor temperature monitoring is triggered. The running speeds"V_ZE1 - V_ZE3" are allocated to the additional inputs"ZE1 - ZE3".
•
The contact "RB- Controller active" is preset from the factory in a way that the relay connects the main contactors (Factory setting INVERS instead of STANDARD used up to now).
•
The terminal designation of the special outputs has been changed in order to be better understandable.
•
The control inputs can be directly connected to an external voltage of 24 V without being modified (see 2.3.3)
Expansions:
•
The input "VZ" is used for post-adjustment (except with installation type "Running gear").
•
Besides the additional input "ZE", two further additional speeds are available (see above).
•
It is possible to connect an encoder with a pulse resolution of 64 - 1024 per revolution andtrack.
•
The input of the encoder evaluation wiring has been completed by a constant current source. (Preresistors probably needed up to now are no longer necessary).
