Motor Power Limit Active

What does FF86 mean?

The drive is limiting motor power based on the limits defined by parameters 20.11 and 20.12. This is an informative alarm indicating the drive is operating at its power limits, potentially due to excessive load or conservative parameter settings. While not an immediate trip, sustained operation at limits can reduce efficiency or prevent desired performance.

• Motor power limit (e.g., P20-11, P20-12) intentionally configured to protect the motor or mechanical system.
• Motor operating at a high speed and torque combination, reaching its maximum output power (e.g., motor operating at 100% rated power).
• Application load exceeding the motor's or drive's continuous power rating.
• Incorrect motor parameters (e.g., P03-01 to P03-08) leading to an inaccurate power calculation.
• Parameter P20-11 (Max Power) or P20-12 (Min Power) set too low for the application's required power output.

Click steps to track your progress.

1. 1

   Review drive parameters P20-11 (Maximum Power Limit) and P20-12 (Minimum Power Limit) to understand the set limits.

2. 2

   Monitor the actual motor power (e.g., r0028) during operation to confirm it is reaching or exceeding the configured limits.

3. 3

   Verify all motor nameplate parameters (P03-01 to P03-08) are accurately entered into the drive to ensure correct power calculation.

4. 4

   Assess the mechanical load on the motor; determine if the application demands higher power than the motor/drive system is rated for.

5. 5

   Consider increasing the value of P20-11 if the motor and mechanical system can safely handle higher power output.
