4 Faults and alarms
4.2 List of faults and alarms
A07321 Drive: Automatic restart active
Message class: Application/technological function faulted (17)
Reaction: NONE
Acknowledge: NONE
Cause: The automatic restart (AR) is active. When the line supply returns and/or the causes of the existing faults are
removed the drive is automatically restarted. The pulses are enabled and the motor starts to rotate.
For p1210 = 26, restarting is realized with the delayed setting of the ON command.
Remedy: - the automatic restart (AR) should, if required, be inhibited (p1210 = 0).
- an automatic restart can be directly interrupted by withdrawing the switch-on command (BI: p0840).
- for p1210 = 26: by withdrawing the OFF2- / OFF3 command.
F07330 Flying restart: Measured search current too low
Message class: Application/technological function faulted (17)
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: During a flying restart, it was identified that the search current reached is too low.
It is possible that the motor is not connected.
Remedy: Check the motor feeder cables.
F07331 Flying restart: Function not supported
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: It is not possible to power up with the motor rotating (no flying restart).
In the following cases, the "flying restart" function is not supported:
PMSM: operation with U/f characteristic and sensorless vector control.
Note:
PMSM: permanent-magnet synchronous motor
Remedy: Deactivate the "flying restart" function (p1200 = 0).
F07332 Flying restart: maximum speed reduced
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: The maximum speed that can be reached is reduced; at very high speeds problems associated with the flying restart
can be encountered.
Possible causes:
- power ratio, power unit/motor too high
Remedy: Parameter changes are not required.
Note:
A flying restart at speeds above 3000 rpm should be avoided.
A07350 (F) Drive: Measuring probe parameterized to a digital output
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The measuring probe is connected to a bi-directional digital input/output and the terminal is set as output.
Alarm value (r2124, interpret decimal):
8: DI/DO 8 (X122.9/X132.1)
9: DI/DO 9 (X122.10/X132.2)
10: DI/DO 10 (X122.12/X132.3)
11: DI/DO 11 (X122.13/X132.4)
12: DI/DO 12 (X132.9)
