84 Compact Operating Instructions, 11/2016, FW V4.7 SP6, A5E39339884B AA
Number
Cause
Remedy
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 V
CE
Check or replace the inverter.
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 filter elements.
• Check whether the ambient temperature is in the permissible range.
F30036 Overtemperature, inside area
F30037 Rectifier 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 inverter or upgrade the inverter firmware.
F30053
Error in FPGA data
Replace the inverter.
F30059
Internal fan defective
Check the internal fan and if required replace.
F30074 Communications fault between
Control Unit and Power Module
There is a communication error 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 off the inverter and switch on again, upgrade the firmware or contact
technical support.
F30664 CU power up aborted Switch off the inverter and switch on again, upgrade the firmware or contact
technical support.
F30850 Software fault in the Power
Module
Replace the inverter or contact technical support.
A30920
Temperature sensor fault
Check that the sensor is connected correctly.
A50001 PROFINET configuration error A PROFINET control is attempting to establish a connection with a faulty
configuration telegram. Check to see whether "Shared Device" is activated
(p8929 = 2).
A50010 PROFINET name of station
invalid
Correct the name of station (p8920) and activate (p8925 = 2).
A50020 PROFINET: Second control
missing
"Shared Device" is activated (p8929 = 2). However, only the connection to a
PROFINET control is present.
