Remedy: If required increase the threshold value phase synchronism (p3813) for synchronizing the line supply
to the drive.
Before OFF1 or OFF3, complete synchronizing (r03819.0 = 0).
Before withdrawing the enable signal (p3802 = 0), reach synchronism (r3819.2 = 1).

207941 <location>Sync-line-drive: Target frequency not permissible
Message Parameter: %1
value:
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The target frequency is outside the permissible value range.
Alarm value (r2124, interpret decimal):
1084: Target frequency greater than the positive speed limit, f_sync > f_max (r1084).
1087: Target frequency less than the negative speed limit, f_sync < f_min (r1087).
Remedy: Fulfill the conditions for the target frequency for line-drive synchronization.
See also: r1084, r1087
207942 <location>Sync-line-drive: Setpoint frequency is completely different
than the target frequency
Message -
value:
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: There is a considerable difference between the setpoint frequency and the target frequency (f_set <>
f_target). The deviation that can be tolerated is set in p3806.
Remedy: The alarm automatically disappears after the difference that can be tolerated between the setpoint and
target frequencies (p3806) is reached.

207943 <location>Sync-line-drive: Synchronization not permitted
Message Parameter: %1
value:
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: Synchronization is not permitted.
Alarm value (r2124, interpret decimal):
1300: The control mode (p1300) has not been set to encoderless closed-loop speed control or V/f
characteristic.
1910: Motor data identification activated.
1960: Speed controller optimization activated.
1990: Encoder adjustment activated.
3801: Voltage Sensing Module (VSM) not found.
3845: Friction characteristic record activated.
Remedy: Fulfill the conditions for the line-drive synchronization.
Re alarm value = 1300:
Set the control mode (p1300) to encoderless closed-loop speed control (p1300 = 20) or V/f character-
istic (p1300 = 0 ... 19).
Re alarm value = 1910:
Exit the motor data identification routine (p1910).
Re alarm value = 1960:
Exist the speed controller optimization routine (p1960).
