4 Faults and alarms
4.2 List of faults and alarms
F07924 Drive: Torque/speed too high
Message class: Application/technological function faulted (17)
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: For p2193 = 1:
The torque deviates from the torque/speed envelope characteristic (too high).
For p2193 = 2:
The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too high).
Remedy: - check the connection between the motor and load.
- adapt the parameterization corresponding to the load.
F07925 Drive: Torque/speed out of tolerance
Message class: Application/technological function faulted (17)
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: For p2193 = 1:
The torque deviates from the torque/speed envelope characteristic.
For p2193 = 2:
The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169).
Remedy: - check the connection between the motor and load.
- adapt the parameterization corresponding to the load.
A07926 Drive: Envelope curve parameter invalid
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: Invalid parameter values were entered for the envelope characteristic of the load monitoring.
The following rules apply for the speed thresholds:
p2182 < p2183 < p2184
The following rules apply for the torque thresholds:
p2185 > p2186
p2187 > p2188
p2189 > p2190
Load monitoring configuration and response must match.
It is not permissible that the individual load torque monitoring areas overlap.
Alarm value (r2124, interpret decimal):
Number of the parameter with the invalid value.
The load torque monitoring has not been activated as long as the alarm is active.
Remedy: - set the parameters for the load monitoring according to the applicable rules.
- if necessary, de-activate the load monitoring (p2181 = 0, p2193 = 0).
A07927 DC braking active
Message class: Application/technological function faulted (17)
Reaction: NONE
Acknowledge: NONE
Cause: The motor is braked with DC current. DC braking is active.
1)
A message with response DCBRK is active. The motor is braked with the braking current set in p1232 for the
duration set in in p1233. If the standstill threshold p1226 is undershot, then braking is prematurely canceled.
2)
DC braking has been activated at binector input p1230 with the DC braking set (p1230 = 4). Braking current p1232 is
injected until this binector input becomes inactive.
Remedy: Not necessary.
The alarm automatically disappears once DC braking has been executed.
