Why is there vibration during operation of my Emerson DC Drives?
- AAmanda ColonAug 22, 2025
Vibration during the operation of Emerson DC Drives can stem from several causes. Incorrectly set speed loop gains (I, P) can cause vibration during any part of the travel. The speed loop gains are split into Start and Travel/Stop sections. Adjust these in Menu I Tuning for both full and no-load conditions. Noise on the position feedback cabling can also lead to unstable control. Ensure good EMC practices regarding cable routing, screen, and terminations. Consider using Drive Encoder Feedback Filter (C09) to limit induced noise. Additionally, high current control loop gains from the autotune process might cause vibration. Manually adjust these gains or implement a current control loop filter. Adjust the current control loop in Menu I Tuning under both full and no-load conditions.
