14 Control and controller functions
3. 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 time-
relay.
•
Switch output for the monitoring of a freely adjustable speed limit.
