[1.7 APPLICATION FUNCT.]
(FUn-)
Output contactor command
This allows the drive to control a contactor located between the drive and the motor. The request for the contactor to close is made when
a run command is sent. The request for the contactor to open is made when there is no longer any current in the motor.
Output contactor feedback
The corresponding logic input should be at 1 when there is no run command and at 0 during operation.
In the event of an inconsistency, the drive trips on an FCF2 fault if the output contactor fails to close (LIx at 1) and on an FCF1 fault if it
is stuck (LIx at 0).
The parameter
[Time to motor run]
(dbS)
can be used to delay tripping in fault mode when a run command is sent and the parameter
[Time to open cont.]
(dAS)
delays the fault when a stop command is set.
Note:
Fault FCF2 (contactor failing to close) can be reset by the run command changing state from 1 to 0 (0 --> 1 --> 0 in 3-wire control).
The
[Out. contactor ass.]
(OCC)
and
[Output contact. fdbk]
(rCA)
functions can be used individually or together.
CAUTION
If a DC injection braking function has been configured it should not be left operating too long in stop mode, as the contactor only
opens at the end of braking.
Failure to follow these instructions can result in equipment damage.
