A07941 Sync-line-drive: Target frequency not permissible
Message value: Parameter: %1
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
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 (Speed limit positive effective), r1087 (Speed limit negative effective)
A07942 Sync-line-drive: Setpoint frequency is completely different than the target frequency
Message value: -
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
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.
See also: p3806 (Sync-line-drive frequency difference threshold value)
A07943 Sync-line-drive: Synchronization not permitted
Message value: Parameter: %1
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
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 U/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 U/f characteristic (p1300 = 0
... 19).
Re alarm value = 1910:
Exit the motor data identification routine (p1910).
Re alarm value = 1960:
Exit the speed controller optimization routine (p1960).
Re alarm value = 1990:
Exit the encoder adjustment (p1990).
Re alarm value = 3801:
Connect the Voltage Sensing Module (VSM), assign it to the synchronizing drive (see p9910, p0151) and enter the
drive object number of the synchronizing drive in p3801. When connecting the VSM to a neighboring drive object,
ensure that the same current controller clock cycle p0115[0] exists as the one in the synchronizing drive.
Re alarm value = 3845:
Exit the friction characteristic record (p3845).
