Why does my Galil DMC-4040 Controller motor oscillate?
- EEdwin FloresAug 2, 2025
Motor oscillation can occur if the gain is too high or the damping is insufficient. To resolve this, decrease the KI and KP values and increase the KD value.

What to do if servo motor runs away when the loop is closed in Galil DMC-4040 Controller?
If the servo motor runs away when the loop is closed, the feedback polarity might be incorrect. Try reversing the motor or encoder wiring. Remember to set the Motor Type back to its default value by using the command MT 1.
How to fix encoder position drifts in Galil DMC-4040 Controller?
Encoder position drift can be caused by noise. To mitigate this: * Shield encoder cables * Avoid placing power cables near encoder cables * Avoid ground loops * Use differential encoders * Use +/-12V encoders.
Why does Galil DMC-4040 Controller motor run away with no connections from controller to amplifier input?
If the motor runs away without connections from the controller to the amplifier input, it could be due to: 1. The amplifier having an internal offset. In this case, adjust the amplifier offset, or compensate for it using the offset configuration on the controller with the OF command. 2. A damaged amplifier. In this case, replace the amplifier.
What to do if unable to read main or auxiliary encoder input on Galil DMC-4040?
If you're unable to read the main or auxiliary encoder input, it could be due to several reasons: 1. Incorrect encoder wiring. Check the encoder wiring. Ensure that for single ended encoders (CHA and CHB only), no connections are made to the CHA- and CHB- inputs. 2. Damaged encoder. Replace the encoder. 3. Incorrect encoder configuration. Check the CE command.
