Remedy
Check the converter's input fuses.
Check the motor cables.
Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
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).
Check the supply voltage on the input terminals.
Check the line voltage setting (p0210).
Check whether the fan is running.

Check the fan filter elements.

Check whether the ambient temperature is in the permissible range.

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.
The 24V voltage supply of the converter (terminals 31 and 32) was
interrupted briefly.
Please check the voltage supply and the wiring.
Check the device supply voltage (p0210).

Check the line reactor dimensioning

Check that the sensor is connected correctly.
A PROFINET controller is attempting to establish a connection with a faulty
configuration telegram. Check to see whether "Shared Device" is activated
(p8929 = 2).
Correct name of station (p8920) and activate (p8925 = 2).
"Shared Device" is activated (p8929 = 2). However, only the connection to a
PROFINET controller is present.
