Faults and Alarms
List of faults and alarms
Cause:
The motor encoder signals that it is not ready.
- initialization of encoder 1 (motor encoder) was unsuccessful.
- the sensor module is defective.
Remedy:
Evaluate other queued faults via encoder 1.
A07580 (F, N)
Drive: No sensor module with the matching component number
Reaction:
NONE
Acknowledge:
NONE
Cause:
A sensor module with the component number specified in p0141 was not found.
Alarm value (r2124, decimal):
Encoder data set involved (index of p0141).
Remedy:
Correct p0141.
Reaction upon F:
OFF1 (DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2)
Acknowledge
IMMEDIATELY (power on)
upon F:
Reaction upon N:
NONE
Acknowledge
NONE
upon N:
F07800
Drive: No power module present
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
The power module parameters cannot be read or no parameters are stored in the power module.
See also: r0200
Remedy:
Connect the data line to power module and restart the control unit (POWER ON).
F07801
Drive: Motor overcurrent
Reaction:
OFF2 (NONE, OFF1, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The permissible motor limit current was exceeded.
- effective current limit set too low.
- current controller not correctly set.
- motor was braked with an excessively high stall torque correction factor.
- V/f operation: Up ramp was set too short or the load is too high.
- V/f operation: Short-circuit in the motor cable or ground fault.
- V/f operation: Motor current does not match the current of motor module.
Note:
Synchronous motor: Limit current= 1.3 * p0323
Induction motor: Limit current= 1.3 * r0209
Remedy:
- check the current limits (p0323, p0640).
- check the current controller (p1715, p1717).
- reduce the stall torque correction factor (p0326).
- increase the up ramp (p1318) or reduce the load.
- check the motor and motor cables for short-circuit and ground fault.
- check the motor module and motor combination.
F07802
Drive: Infeed or power module not ready
Reaction:
OFF2 (NONE)
Acknowledge:
IMMEDIATELY
Cause:
After an internal power-on command, the infeed or drive does not signal ready.
- monitoring time is too short.
- DC link voltage is not present.
- associated infeed or drive of the signaling component is defective.
- supply voltage incorrectly set.
Remedy:
- increase the monitoring time (p0857).
- ensure that there is a DC link voltage. Check the DC-link busbar. Enable the infeed.
- replace the associated infeed or drive of the signaling component.
- check the line supply voltage setting (p0210).
