Speed loop error
Indramat · Indradrive
¿Qué significa 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.
Causas comunes
- 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
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
Inspect the mechanical system for any backlash, play, or binding that could introduce instability.
- 3
Verify the integrity and signal quality of the motor encoder. Check for loose connections or electrical noise.
- 4
Ensure the load on the motor is stable and within the drive's capabilities.
- 5
Check for any other active faults or warnings that might be related to motor feedback or current control.
