F30074 Communications error between
Control Unit and Power Module
There is a communications fault between the Control Unit and the Power
Module. Possible causes:
● The Control Unit may have been removed or inserted incorrectly.
● 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 the Control Unit off and on again, upgrade the firmware or contact
technical support.
F30664 CU power up aborted Switch the Control Unit off and on again, upgrade the firmware or contact
technical support.
F30850 Software fault in the Power Module Replace Power Module 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 an incor‐
rect configuration telegram. Check 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 available.
