What it means
F30071 is raised when the drive stops receiving new actual values from its power unit module: more actual value telegrams have failed than the drive permits. On G120 and G120XA the manual words the same condition as more than one failed actual value telegram. The drive coasts down (OFF2) and the fault must be acknowledged immediately before it will start again.
Why it appears
- Actual value telegrams from the power unit module have failed in greater number than the drive permits.
- On G120 and G120XA this is worded as: more than one actual value telegram from the power unit module has failed.
What to check
- Check the interface to the power unit module.
- Check that the interface is correctly adjusted and locked.
Acknowledging and restarting
The fault must be acknowledged immediately; the drive will not start again until the acknowledgement is made.
What differs between the drive families
Straight from the manuals' own fields — F30071 is not described identically everywhere.

Questions technicians ask
What does fault F30071 mean on a SINAMICS drive?
The drive is no longer receiving new actual values from the power unit module because more actual value telegrams have failed than permitted. The drive coasts down and the fault must be acknowledged before it will start again.
How do I fix fault F30071?
Check the interface to the power unit module, including its adjustment and locking. Then acknowledge the fault immediately.
Is F30071 on a G120 different from other SINAMICS drives?
Only in wording: for G120 and G120XA the manual states that more than one actual value telegram from the power unit module has failed, while the other manuals speak of the permissible number being exceeded. The remedy is identical — check the interface (adjustment and locking) to the power unit module.
