F07840 Drive: Infeed operation missing
Message value: -
Message class: Infeed faulted (13)
Drive object: VECTOR_G
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The signal "infeed operation" is not present although the enable signals for the drive have been present for longer
than the parameterized monitoring time (p0857).
- infeed not operational.
- interconnection of the binector input for the ready signal is either incorrect or missing (p0864).
- infeed is presently carrying out a line supply identification routine.
Remedy: - bring the infeed into an operational state.
- check the interconnection of the binector input for the signal "infeed operation" (p0864).
- increase the monitoring time (p0857).
- wait until the infeed has completed the line supply identification routine.

F07841 (A) Drive: Infeed operation withdrawn
Message value: -
Message class: Infeed faulted (13)
Drive object: VECTOR_G
Reaction: OFF2 (NONE, OFF1, OFF3)

- 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 "infeed operation" signal (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 parameterized for
NONE, OFF1 or OFF3. so that the drive can continue to operate even after the infeed fails.
