What it means
F07895 is issued by the drive's load monitoring when this is configured for a pump or fan (p2193 = 4 or 5). In this configuration the monitoring function detects when the driven machine is operating under no-load conditions, with the detection torque threshold p2191 serving as the detection limit. The fault therefore points to the process side: the pump or fan is running without doing its work.
Why it appears
- The pump is running dry — there is no medium available to be pumped.
- The fan belt is broken.
- The detection torque threshold (p2191) may be set too low.
What to check
- For a pump: check the medium being pumped and provide the medium if required.
- For a fan: check the belt and replace it if required.
- If necessary, increase the detection torque threshold in p2191.
Parameters the manual names
- p2193 — Load monitoring configuration: the setting (values 4 or 5) that arms pump/fan monitoring and with it this no-load fault.
- p2191 — Load monitoring torque threshold no load: the detection limit for the no-load condition; increase it as part of the remedy when the threshold itself is set too low.
- p2181 — Load monitoring response: sets how the load monitoring responds; the manual cross-references it under this fault, so verify the configured response when diagnosing.
Acknowledging and restarting
The fault reaction stops the drive. The fault can be acknowledged immediately, without any waiting time. Remedy the cause first — provide the pumped medium, replace the fan belt, or raise p2191 if the threshold is set too low — then acknowledge the message and restart the drive.
What differs between the drive families
Straight from the manuals' own fields — F07895 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G120 | OFF1 (NONE, OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | — | SINAMICS G120 · p. 885 |
| G120XA | OFF1 (NONE, OFF2, OFF3) | IMMEDIATELY | — | — | SINAMICS G120XA PN converter · p. 1136 |

Questions technicians ask
What does fault F07895 mean on a SINAMICS drive?
The pump/fan load monitoring (p2193 = 4 or 5) has detected a no-load condition — typically a pump running dry with no medium to be pumped, or a fan with a broken belt.
Why does F07895 trip although the machine appears to be working?
The manual names the detection torque threshold p2191 as a possible cause: it may be set too low, and increasing it is part of the remedy.
How do I clear and reset F07895?
Remedy the cause first — provide the pumped medium or replace the fan belt — then acknowledge the fault immediately and restart the drive. The message can be acknowledged without any waiting time.
Which parameters are linked to F07895?
p2193 (load monitoring configuration), p2191 (load monitoring torque threshold no load) and p2181 (load monitoring response).
