F07924 — Drive: Torque/speed too high

F07924 is the load monitoring fault: the drive has detected a torque or speed that is too high for the monitored condition. What is monitored is set in p2193. With p2193 = 1 the drive checks the torque against a torque/speed envelope characteristic and raises the fault when the torque lies too high. With p2193 = 2 the drive compares the speed signal of an external encoder, interconnected in p3230, with its smoothed actual speed r2169 and raises the fault when the encoder speed lies too high. Both variants are described for G120 and G120XA; for S120/S150 and G130/G150 the manuals give the envelope deviation only, and for G115D and G120C they list the message title without further detail. The codes F07923 Drive: Torque/speed too low and F07925 Drive: Torque/speed out of tolerance are separate messages.

• p2193 = 1: the torque deviates from the torque/speed envelope characteristic — it lies too high.
• p2193 = 2: the speed signal from the external encoder (refer to p3230) deviates from the smoothed actual speed r2169 — it is too high. The manual describes this encoder comparison for G120 and G120XA; on S120/S150 and G130/G150 only the envelope deviation is given as the cause.

1. Check the connection between the motor and the load.
2. Adapt the parameterization to the actual load — with p2193 = 1 the torque/speed envelope characteristic, with p2193 = 2 the encoder speed interconnection in p3230.

• p2193 (load monitoring configuration): selects what the load monitoring compares for this fault — 1 = torque against the torque/speed envelope characteristic, 2 = external encoder speed against the actual speed.
• p3230 (CI: load monitoring speed actual value): the interconnection through which the external encoder speed reaches the load monitoring; relevant when p2193 = 2.
• r2169 (CO: actual speed smoothed): the drive's smoothed actual speed that serves as the reference value in the comparison when p2193 = 2.

Depending on the configured reaction, the drive brakes along the ramp to a standstill (OFF1), coasts down (OFF2), executes a fast stop (OFF3) or takes no automatic action when this fault occurs. Once the cause has been removed, the fault can be acknowledged immediately — for example from the operator panel or the commissioning tool — and the drive can then be started again.
