Operation downstream from step controller
Contrac actuators can be driven using step controller pulses instead of an analog setpoint. The following conditions must be fulfilled
in order to implement the step controller pulses:
•
The binary inputs must be configured using the 'STEP CONTROLLER' function.
•
The binary input 1 must be connected with +24 V DC (automatic operation).
•
The 'AUT' operating mode must be selected through the graphic user interface.
