Motor Power Limit

What does FF86 mean?

The drive is actively limiting motor power according to the boundaries defined by parameter 20.11 (P MOTORING LIM) for motoring and 20.12 (P GENERATING LIM) for generating. This is an informative alarm (programmable Fault Function 30.23, bit 4: MOT_POW_LIM_IND) indicating the drive is operating at its configured power limits.

• Motor output power has exceeded its configured limit (P4-01).
• Load torque is too high for the motor's capacity.
• Mechanical issue causing excessive motor strain.
• Control loop parameters (e.g., P3-07) set incorrectly leading to over-powering.

Click steps to track your progress.

1. 1

   Check parameter 20.11 (P MOTORING LIM) and 20.12 (P GENERATING LIM) settings to ensure they are appropriate for the application.

2. 2

   Review Fault Function parameters, specifically 30.23 (LIMIT WARNING), which activates this alarm, to understand its configuration.
