F30011 Line phase failure Check the converter's input fuses.
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).
F30027 Time monitoring for DC link pre-
charging
Check the line voltage.
Check the line voltage setting (p0210).
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
Check the internal fan and if required replace.
Check the internal fan and if required replace.
F30074 Communications fault between
Control Unit and Power Module
The 24V voltage supply of the converter (terminals 31 and 32) was
interrupted briefly.
Please check the voltage supply and the wiring.
A30502 DC link overvoltage
• Check the device supply voltage (p0210).
• Check the line reactor dimensioning
Check that the sensor is connected correctly.
A50001 PROFINET configuration error A PROFINET controller is attempting to establish a connection with a faulty
configuration telegram. Check to see whether "Shared Device" is activated
A50010 PROFINET name of station
Correct name of station (p8920) and activate (p8925 = 2).
A50020 PROFINET: Second controller
activated (p8929 = 2). However, only the connection to a
PROFINET controller is present.
