Solution
Motor data. Perform commissioning, if necessary.
Motor connection method (Υ / Δ).
V/f operation, the assignment of the rated currents of the motor and power unit.
Line quality.
The line commutating reactor must be connected properly.
Power cable connections.
Power cables for short-circuit or ground fault
Power cable length
Line phases
If the fault is still present:
V/f operation: Increase the up ramp.
Reduce the load.
Replace the power unit.
Increase the ramp-down time (p1121).
Set the rounding times (p1130, p1136).
Activate the DC link voltage controller (p1240, p1280).
Check the line voltage (p0210).
Check the line phases.
Check the line voltage (p0210).
Check the line phases.
Check whether the drive fan is running.
Check the ambient temperature.
Check whether the motor is overloaded.
Reduce the pulse frequency.
Check the rated currents of the motor and Power Module.
Reduce current limit p0640.
When operating with V/f characteristic: Reduce p1341.
Check the drive's input fuses.
Check the motor cables.
Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
Check the power cable connections.
Check the motor.
Check the current transducer.
Check the cables and contacts of the brake connection (a wire might be
broken).
Check the Power Module.
Replace the Power Module, if necessary.
Check the supply voltage at the input terminals.
Check the line voltage setting (p0210).
Check whether the fan is running.
Check the fan elements.
Check the ambient temperature.
Check whether the fan is running.
Check the fan elements.
Check the ambient temperature.
Check the motor load.
Check the line phases.
