What it means
F01910 is raised when the reception of setpoints from the fieldbus interface is interrupted. The manuals name the onboard interface and PROFIBUS/PROFINET/USS as the affected paths; on G120C the MODBUS master also appears among the communication partners that can trigger it. Setpoint reception is monitored with the time in p2040; when no setpoints arrive within that window, the drive aborts with its configured stop reaction and displays this fault. Depending on the drive configuration, the same condition can also be issued as an alarm (A) or with no reaction (N).
Why it appears
- The bus connection is interrupted.
- The higher-level controller (communication partner) has been switched off — on G120C the manual names the MODBUS master explicitly.
- The controller has been set into the STOP state; on G120 with PROFIBUS this means the PROFIBUS master is in STOP.
- A communications error — CRC, parity bit or logical error (listed for G120C and G115D).
- An excessively low value for the fieldbus monitoring time p2040 (listed for G120C and G115D).
What to check
- Restore the bus connection and switch the communication partner back on.
- Set the higher-level controller to RUN; for PROFIBUS, set the PROFIBUS master to RUN.
- If setpoints still fail to arrive although the bus is intact, adapt p2040 — an excessively low monitoring time is itself listed as a cause.
- If the fault repeats on PROFIBUS, check the set response monitoring in the bus configuration (HW Config).
- With slave redundancy, observe the manual's restriction:
For operation on a Y link, it must be ensured that “DP alarm mode = DPV1” is set in the slave parameterization.
Parameters the manual names
- p2040 — COMM INT monitoring time (COMM INT t_mon): the fieldbus interface monitoring time for this fault; adapt it when setpoint reception fails although the bus is intact, since an excessively low value is listed as a cause.
- p2047 — PROFIBUS additional monitoring time (PB suppl t_mon): the additional PROFIBUS monitoring time, named by the manual alongside p2040 for this fault.
Acknowledging and restarting
Remove the cause first: restore the bus connection and set the higher-level controller (for PROFIBUS, the PROFIBUS master) to RUN. The fault can then be acknowledged immediately; the manuals describe no further reset procedure for it. Once it is acknowledged and setpoints are arriving again, the drive can be restarted.
What differs between the drive families
Straight from the manuals' own fields — F01910 is not described identically everywhere.

Questions technicians ask
What does SINAMICS fault F01910 mean?
The drive has stopped receiving setpoints from the higher-level control system over the fieldbus, so it aborts with its configured stop reaction. The same condition can also be output as an alarm (A) or with no reaction (N), depending on the drive configuration.
Why does F01910 keep occurring?
Typical causes are an interrupted bus connection, a controller that is switched off or in STOP, a communications error (CRC, parity bit, logical error) or an excessively low p2040 monitoring time. On PROFIBUS, repeated occurrences point to the response monitoring set in the bus configuration (HW Config).
How do I clear and reset F01910?
Restore the bus connection and set the controller (for PROFIBUS, the PROFIBUS master) to RUN, then acknowledge the fault — it may be acknowledged immediately. If required, adapt p2040.
Which parameter is the fieldbus monitoring time for F01910?
p2040, the COMM INT monitoring time, monitors setpoint reception. p2047, the PROFIBUS additional monitoring time, is named alongside it for this fault.
