What it means
F30072 is raised when the drive can no longer transfer its setpoint telegrams to the power unit module — the G120 and G120XA manuals title it "Setpoints can no longer be transferred to the Power Module". Concretely, more than one setpoint telegram was not able to be transferred to the power unit module. The S120, S150, G130 and G150 manuals state this explicitly for CU31x and CUA31; the G120 and G120XA manuals print the same cause without that qualifier. The drive files the fault under the internal (DRIVE-CLiQ) communication errors.
Why it appears
More than one setpoint telegram was not able to be transferred to the power unit module.
All the manuals describe the code with this single cause; only the S120, S150, G130 and G150 entries add that the statement applies for CU31x and CUA31.
What to check
- Check the interface to the power unit module — its adjustment and its locking. This is the remedy the manuals give for this code, worded identically for all the families listed.
Acknowledging and restarting
The drive coasts down when this fault trips and must be acknowledged before it will start again. Acknowledge F30072 immediately once the interface to the power unit module has been checked and put right, then restart the drive.
What differs between the drive families
Straight from the manuals' own fields — F30072 is not described identically everywhere.

Questions technicians ask
What does fault F30072 mean on a SINAMICS drive?
More than one setpoint telegram could not be transferred to the power unit module (called the Power Module in the G120 and G120XA manuals), so the drive no longer receives its setpoints.
How do I clear fault F30072?
Check the interface to the power unit module — its adjustment and its locking. Then acknowledge the fault immediately and restart the drive.
Is F30072 the same fault on a G120 as on an S120 or G150?
Yes. The manuals describe it identically; only the S120, S150, G130 and G150 entries add that the cause statement applies for CU31x and CUA31.
