207841 <location>Drive: Infeed operation withdrawn
Message -
value:
Drive object: SERVO, VECTOR
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The signal "infeed operation" was withdrawn in operation.
- interconnection of the binector input for the signal "infeed operation" is either incorrect or missing
(p0864).
- the enable signals of the infeed were disabled.
- due to a fault, the infeed withdraws the signal "infeed operation".
Remedy: - check the interconnection of the binector input for the signal "infeed operation" (p0864).
- check the enable signals of the infeed and if required, enable.
- remove and acknowledge an infeed fault.
Note:
If this drive is intended to back-up the DC link regeneratively, then the fault response must be param-
eterized for NONE, OFF1 or OFF3 so that the drive can continue to operate even after the infeed fails.
