Number Cause Remedy
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 lter elements.
• Check whether the ambient temperature is in the permissible range.
F30036 Overtemperature, inside area
