Speed loop error

Hva betyr F8078 ?

The IndraDrive detected an excessive deviation or instability in the motor's actual speed compared to the commanded speed, indicating a problem with the speed control loop. This can result in poor motor performance, oscillations, or inability to maintain target velocity.

• Incorrectly tuned speed loop parameters (e.g., gain, integral time).
• Mechanical binding or excessive play in the motor and load system.
• Inaccurate or noisy speed feedback from the encoder.
• Unstable or fluctuating load on the motor.
• Motor or drive internal fault affecting current delivery or speed measurement.

1. 1

   Review and carefully re-tune the speed controller parameters (e.g., S-0-0108 Velocity Control Loop Gain Kp, S-0-0109 Velocity Control Loop Integral Time Tn) according to the manual's auto-tuning or manual tuning guidelines.

2. 2

   Inspect the mechanical system for any backlash, play, or binding that could introduce instability.

3. 3

   Verify the integrity and signal quality of the motor encoder. Check for loose connections or electrical noise.

4. 4

   Ensure the load on the motor is stable and within the drive's capabilities.

5. 5

   Check for any other active faults or warnings that might be related to motor feedback or current control.
