Remedy: - check the parameterized line frequency and if required change (p0211).
- check the alarm threshold (p0285).
- check the line supply.
- check the line supply quality.

206400 <location>Infeed: Line supply data identification selected/active
Message -
value:
Drive object: A_INF, S_INF
Reaction: NONE
Acknowledge: NONE
Cause: The line supply data identification is selected and active.
The line inductance and the DC link capacitance are measured at the next pulse enable.
See also: p3410 (Infeed identification method)
Remedy: No remedial action required.
206500 <location>Infeed: Line synchronization not possible
Message -
value:
Drive object: A_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 determined 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.
- when a Voltage Sensing Module (VSM) is used: check the line supply to the VSM terminals X521 or
X522.
- check the line supply quality.

206601 <location>Infeed: Current offset measurement interrupted
Message %1
value:
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.
206602 <location>Infeed: Current offset measurement not possible
Message -
value:
Drive object: A_INF, B_INF, S_INF
Reaction: NONE
Acknowledge: NONE
