Limit switches
DI0: Preparation for Open limit motor off
DI1: Motor off, start only in Open direction
DI3:
•Motor off if prepared for Open off, start only
in Closed direction
•Fault if not prepared or if during closing
Remark:
•The limit switch Closed prepares the stop.
Torque closed stops the motor. Starting is
only possible in the opposite direction
•The single torque signals in the telegram -
torque Open or torque Closed - are calcu-
lated based on the direction of movement
before the stop.
Definitions and monitoring signals particular to the control functions Actuator 1,2,3 and 4
•Input signals: Open and Closed inputs are active signals, torque input is a closed loop signal.
•The two torque signals are connected in series. The discrete torque signal is created based on the previ-
ous direction of movement.
Remark:
If DI2 is not needed as fault input it can be connected to the link between the torque contacts to find out
which torque signal is active.
•Run-time Open <-> Closed: The Run-time limit (= Star-delta starting time) must be changed and should
be set according to actuator data. Setting the Run-time limit = 1 s disables the supervision.
•Starting from Open or Closed: The limit switch has to open within the start monitoring time of 3 s.
Exceeding the time results in the fault signal Open limit switch 1 -> 0 not occurring within 3 s after the
Closed command. The start monitoring time can be extended.
•A faulty torque signal in the intermediate position sets the internal fault signal. The motor is stopped and
can be started again
- after fault reset via fieldbus or other - AND -
- only in the opposite direction (previous direction is blocked).
After starting the torque signal must disappear within 0.5 s. Otherwise the internal fault signal is set
again. A fault reset and start in the opposite direction can be repeated as often as desired.
•If after powering up a torque signal (0-signal) is present and neither an Open nor a Closed signal is pre-
sent it is presumed that the torque occurred during closing. The motor can be started:
- after fault reset via fieldbus or other - AND -
- only in the Open direction
