Remedy
Check the following:
Motor data, if required, carry out commissioning
•
Motor's connection method (Υ / Δ)
•
U/f operation: Assignment of rated currents of motor and Power Module
•
Line quality
•
Make sure that the line commutating reactor is connected properly
•
Power cable connections
•
Power cables for short-circuit or ground fault
•
Power cable length
•
Line phases
•
If this doesn't help:
U/f operation: Increase the acceleration 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 whether the converter fan is running.
Check whether the ambient temperature is in the permissible range.
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 U/f characteristic: Reduce p1341.
Check the converter'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 transformer.
•
Check the cables and contacts of the brake connection (a wire might be
•
broken).
Check the line voltage.
Check the line voltage setting (p0210).
Check whether the fan is running.
•
Check the fan filter elements.
•
Check whether the ambient temperature is in the permissible range.
