FF86

Motor Power Limit

ABB · ACS800 Standard Firmware

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.

Common Causes

  • 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.
