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 converter.
Reduce the current limit p0640.
When operating with U/f characteristic: Reduce p1341.
F30011 Line phase failure Check the converter's input fuses.
Check the motor 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 converter.
F30027 Time monitoring for DC link pre-
charging
Check the line voltage.
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
F30037 Recti󹪝er overtemperature See F30035 and, in addition:
• Check the motor load.
• Check the line phases
A30049 Internal fan defective Check the internal fan and if required replace.
F30052 Incorrect Power Module data Replace the converter or upgrade the converter 󹪝rmware.
F30053 Error in FPGA data Replace the converter.
F30059 Internal fan defective Check the internal fan and if required replace.
F30074 Communications error between
Control Unit and Power Module
There is a communications fault between the Control Unit and the Power
Module. Possible cause:
• The external 24 V Control Unit power supply has dipped to ≤95% of the
rated voltage for ≤3ms
A30502 DC link overvoltage
• Check the device supply voltage (p0210).
• Check the line reactor dimensioning
F30662 CU hardware fault Switch o󹪜 the converter and switch on again, upgrade the 󹪝rmware or contact
technical support.
F30664 CU power up aborted Switch o󹪜 the converter and switch on again, upgrade the 󹪝rmware or contact
technical support.
F30850 Software fault in the Power Mod‐
ule
Replace the converter or contact technical support.
A30920 Temperature sensor fault Check that the sensor is connected correctly.
