Feedback error
Danfoss · VLT HVAC Drive High Power
What does 61 mean?
An inconsistency has occurred between the calculated motor speed and the speed measurement received from the feedback device (e.g., encoder). This indicates a potential issue with the feedback device, its wiring, or the drive's speed calculation, which can lead to unstable speed control or unexpected motor behavior.
Complete Troubleshooting Guide
- 1
Check the wiring and connections of the motor feedback device (encoder) for looseness or damage.
- 2
Verify the configuration of parameters 4-30, 4-31, and 4-32 for appropriate error tolerance and timeout settings.
- 3
Inspect the feedback device itself for functionality and accuracy.
- 4
Ensure the motor feedback is correctly configured, especially during commissioning.
