F30001
Overcurrent
Check the following:
• Motor data, if required, carry out commissioning
• Motor 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
F30002
DC-link voltage overvoltage
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.
F30003
DC-link voltage undervoltage
Check the line voltage (p0210).
F30004
Converter overtemperature
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.
F30005
I2t converter overload
Check the rated currents of the motor and Power Module.
Reduce current limit p0640.
When operating with U/f characteristic: Reduce p1341.
F30011
Line phase failure
Check the converter's input fuses.
Check the line cables.
F30015
Motor cable phase failure
Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
F30021
Ground fault
• 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).
F30022
Power Module: Monitoring U
CE
Check or replace the Power Module.
F30027
Time monitoring for DC link pre-
charging
Check the supply voltage at the input terminals.
Check the line voltage setting (p0210).
F30035
Overtemperature, intake air
• Check whether the fan is running.
• Check the fan filter elements.
• Check whether the ambient temperature is in the permissible range.
F30036
Overtemperature, inside area
