MOT POW LIM

What does FF86 mean?

The ABB ACS800 drive is actively limiting motor power according to the limits defined by parameters 20.11 (P MOTORING LIM) and 20.12 (P GENERATING LIM). This is an informative alarm (3.18 AW 5 bit 12) indicating the drive is operating near its power boundaries, potentially due to application demands or restrictive parameter settings, and its behavior can be configured via Fault Function 30.23.

• Application demands exceed the maximum motor power limit set by parameter 20.11 (P MOTORING LIM).
• Application generates excessive power, exceeding the regenerative power limit set by parameter 20.12 (P GENERATING LIM).
• Incorrect settings of parameter 20.11 or 20.12, which may be too restrictive for the application's actual power requirements.
• Fault Function parameter 30.23 (LIMIT WARNING) is configured to activate this informative alarm.

Click steps to track your progress.

1. 1

   Check parameter 20.11 (P MOTORING LIM) and 20.12 (P GENERATING LIM) settings in the ABB ACS800 drive to ensure they are appropriate for the motor and application's peak power requirements.

2. 2

   Evaluate the application's power demands during motoring and generating modes; reduce the load or adjust the operating cycle if the limits are consistently being hit.

3. 3

   Verify parameter 30.23 (LIMIT WARNING) to ensure it is configured as desired for informative alarm activation and not causing unnecessary interruptions.

4. 4

   Ensure all motor parameters in group 99 START-UP DATA are correctly entered and that a motor ID run has been successfully completed for accurate power calculation.

5. 5

   Consider if the motor or drive are appropriately sized for the peak power demands of the application; upgrading might be necessary.
