What it means
A07922 "Drive: Torque/speed out of tolerance" comes from the drive's load monitoring. It reports that the monitored quantities no longer match the configured envelope: the torque deviates from the torque/speed envelope characteristic. The manuals for the S120, S150, G130 and G150 name only this torque check. The G120 and G120XA manuals describe the code more fully: which check raises it depends on p2193 — with p2193 = 1 the torque envelope is monitored, with p2193 = 2 the speed signal from the external encoder (refer to p3230) is compared with the speed (r2169). For the G115D and G120C the manuals list the message by title only.
Why it appears
- The torque deviates from the torque/speed envelope characteristic — the only cause the S120/S150 and G130/G150 manuals print (there for the Motor component), and the case assigned to p2193 = 1 in the G120/G120XA manuals.
- With p2193 = 2 (G120, G120XA): the speed signal from the external encoder (refer to p3230) deviates from the speed (r2169).
What to check
- Check the connection between the motor and the load.
- Adapt the parameterization so that it corresponds to the load; p2193 determines which monitoring raises the message (1: torque/speed envelope characteristic, 2: external encoder speed via p3230 compared with r2169), so its setting must match the monitoring actually intended.
Parameters the manual names
- p2193 (Load monitoring configuration): selects which monitoring raises A07922 — 1 monitors the torque against the torque/speed envelope characteristic, 2 compares the external encoder speed with r2169.
- p3230 (CI: Load monitoring speed actual value): signal source of the external encoder speed that is checked when p2193 = 2.
- r2169 (CO: Actual speed smoothed signals): smoothed actual speed of the drive, the reference the external encoder speed is compared against when p2193 = 2.
Acknowledging and restarting
A07922 requires no acknowledgement and the drive performs no automatic reaction; the message clears by itself once monitoring no longer detects the deviation.

Questions technicians ask
What does alarm A07922 mean on a SINAMICS drive?
The load monitoring reports "Torque/speed out of tolerance": the torque deviates from the torque/speed envelope characteristic, or — with p2193 = 2 — the speed of the external encoder (refer to p3230) deviates from the speed (r2169).
How is A07922 acknowledged or reset?
No acknowledgement is needed and the drive takes no automatic reaction. Check the connection between motor and load, adapt the parameterization to the load, and the alarm clears itself once the deviation is gone.
Which parameters belong to A07922?
p2193 configures the load monitoring (1: torque/speed envelope characteristic, 2: external encoder speed), p3230 selects the encoder speed signal, and r2169 provides the smoothed actual speed used as the comparison value.
Why does the drive keep running with A07922 active?
The message is raised as an alarm without a reaction, so the drive continues to operate; it only signals that monitoring sees the torque or encoder speed outside the configured tolerance, which should be investigated.
