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 in FCF2 if the output contactor fails to close (LIx at 1) and in
FCF1 if it is stuck (LIx at 0).
The [Delay to motor run]
(dbS) parameter can be used to delay tripping in fault mode when a run command
is sent and the [Delay to open cont.] (dAS) parameter delays the detected fault when a stop command is
set.
Note: 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
RISK OF DAMAGE TO THE MOTOR
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.
