F06500 Infeed: Line synchronization not possible
Drive object: A_INF, B_INF, S_INF
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The line synchronization is not possible within the monitoring time.
The infeed was re-synchronized to the line supply because it was interrupted due to a line frequency that was deter-
mined to be either too low or too high.
After 20 attempts, synchronization - and therefore also the power-on operation - were interrupted.
Remedy: - check the parameterized line frequency and if required change (p0211).
- check the setting of the threshold values (p0284, p0285).
- check the line supply.
- check the line supply quality.

frequency fallen below, alarm threshold)
A06601 (F) Infeed: Current offset measurement interrupted
Drive object: A_INF, B_INF, S_INF
Reaction: NONE
Acknowledge: NONE
Cause: Defective current measurement or a DC current is present during the offset measurement.
Alarm value (r2124, interpret decimal):
1: Excessively high phase current has occurred during the current-offset calibration.
2: The measured current - offset is greater than the 3% of the maximum permissible converter current (e.g. due to a
ground fault in the DC link).
Remedy: Re alarm value = 1:
- possible counter-measure if there is no line contactor: Power-up an adequately long time before OFF1 = 1.
Re alarm value = 2:
- defective current measurement or a DC current is present during the offset measurement.
- check the DC link for a ground fault.
Reaction upon F: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A06602 (F) Infeed: Current offset measurement not possible
Drive object: A_INF, B_INF, S_INF
Reaction: NONE
Acknowledge: NONE
Cause: After an OFF1 = 1 no valid current offset measurement was able to be made within the monitoring time (p3491)
before closing the line contactor. The current offset is set to 0.
See also: p3491 (Infeed I-offset measurement monitoring time)
Remedy: - check the DC link for a ground fault. A ground fault can destroy parts and components!
- Check the monitoring time setting and if required increase (p3491). At least 100 ms is required for a valid measure-
ment (p3491 > 100 ms).
Notice:
If there is no valid measurement, then under certain circumstances the quality of the DC link control will be reduced.

Reaction upon F: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
F06700 (A) Infeed: Switch line contactor for load condition
Drive object: A_INF, B_INF, S_INF
Reaction: NONE (OFF2)
Acknowledge: IMMEDIATELY
Cause: For an ON command, the infeed line contactor should be switched under load.
