Motor Torque Limit

What does FF85 mean?

The drive is actively limiting motor torque based on the calculated motor pull-out torque limit and the minimum/maximum torque limits defined by parameters 20.13 (MIN TORQ SEL) and 20.14 (MAX TORQ SEL). This is an informative alarm (programmable Fault Function 30.23, bit 3: MOT_TORQ_LIM_IND) indicating the drive is operating at its configured torque boundaries.

Additional Steps

Steps 1–2 are listed in Priority Fix.

   If LIMIT WORD 1 bit 0 (TORQ MOTOR LIM) is active, verify motor parameter settings in group 99 (START-UP DATA) and confirm that an ID run has been completed successfully.
