What it means
F01915 is a group display for problems with the sign-of-life of the master during clock cycle synchronous (isochronous) operation. It is raised on drive object 1, which is the Control Unit. For central measurements, synchronism with the central master is lost. The abbreviations in the message name the bus involved: PB stands for PROFIBUS and PN for PROFINET. Depending on how the drive is configured, the same condition can also be issued as an alarm (A) or as a message with no reaction (N).
Why it appears
- This is a group display: it collects problems with the sign-of-life of the master in isochronous operation, reported on drive object 1, which is the Control Unit.
- For central measurements, synchronism with the central master is lost.
Acknowledging and restarting
Acknowledge the message immediately. The drive does not take any automatic action in response to this condition. Beyond acknowledging it, the manual describes no further reset or repair steps for this message.
The same on every family

Questions technicians ask
What does fault F01915 mean on a SINAMICS S120 or S150?
It is a group display for problems with the sign-of-life of the master during clock cycle synchronous (isochronous) operation on drive object 1, the Control Unit. For central measurements, synchronism with the central master is lost.
Does F01915 stop the drive?
No. The drive does not take any automatic action in response to this condition. Depending on the configuration, the same condition can also be issued as an alarm (A) or with no reaction (N).
How do I clear fault F01915?
Acknowledge the message immediately. The manual describes no further reset or repair steps for this code.
What do PB and PN stand for in F01915?
PB is the manual's abbreviation for PROFIBUS and PN for PROFINET.
