A07825 (N) Drive: Simulation operation activated
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The simulation mode is activated.
The drive can only be powered-up if the DC link voltage is less than 40 V.
Remedy: The alarm automatically disappears if simulation operation is de-activated with p1272 = 0.
Reaction upon N: NONE
Acknowl. upon N: NONE
F07826 Drive: Simulation operation with DC link voltage too high
Drive object: VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The simulation mode is activated and the DC link voltage is greater than the permissible value of 40 V.
Remedy: - switch-out (disable) simulation operation (p1272 = 0) and acknowledge the fault.
- reduce the input voltage in order to reach a DC link voltage below 40 V.
F07840 Drive: Infeed operation missing
Drive object: SERVO, VECTOR
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F07841 Drive: Infeed operation withdrawn
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Cause: The signal "infeed operation" was withdrawn in operation.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 parameterized for
NONE so that the drive can continue to operate even after the infeed fails.
A07850 (F) External alarm 1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The BICO signal for "external alarm 1" was triggered.
The condition for this external alarm is fulfilled.
See also: p2112 (External alarm 1)
Remedy: Eliminate the causes of this alarm.
