Why does the motor run away when the loop is closed in my Galil DMC-2X00 Controller?
If your motor runs away when the loop is closed on your Galil Controller, it's likely due to incorrect feedback polarity. To fix this, invert the polarity of the loop by inverting the motor leads (for brush type motors) or the encoder.
Why does the motor oscillate with my Galil Controller?
If the motor oscillates with the Galil Controller, it's likely due to a gain that's too high or insufficient damping. To resolve this, decrease KI and KP, and increase KD.
What to do if I cannot communicate with the Galil Controller using a terminal emulator?
If you're experiencing issues communicating with the Galil Controller using a terminal emulator, the selected communication port might be incorrect. Try using a different COM port to establish a connection.
Why can't I communicate with the Galil DMC-2X00 Controller using a terminal emulator?
If you're experiencing issues communicating with the Galil Controller using a terminal emulator, the selected baud rate might be incorrect. Ensure the baud rate matches the DIP switch settings on the controller, and adjust as needed.
What to do if my Galil Controller does not read changes in encoder position?
If the Galil Controller does not read changes in encoder position, the encoder connections might be incorrect. Check the encoder wiring to ensure it is properly connected.
Why doesn't my Galil DMC-2X00 Controller read changes in encoder position?
If the Galil Controller does not read changes in encoder position, the encoder may be faulty. Check the encoder signals and replace the encoder if necessary.
What causes the Galil Controller to not read changes in encoder position?
If the Galil Controller does not read changes in encoder position, the controller might be faulty. Connect the encoder to a different axis input. If it works, this indicates a controller failure, and you should consider repair or replacement.
Why doesn't the motor complete its move with the Galil DMC-2X00?
If the motor does not complete a move with the Galil Controller, noise on the limit switches might be stopping the motor. Verify this by checking the stop code (SC). If limit switch noise is the cause, reduce the noise.
Why does the motor run away when connected to the amplifier with no inputs on my Galil DMC-2X00?
If the motor runs away when connected to the amplifier with no additional inputs in your Galil Controller setup, the amplifier offset may be too large. Adjust the amplifier offset to resolve this issue.
What to do if the motor still runs away after adjusting the offset on my Galil Controller?
If the motor still runs away (when connected to the amplifier with no additional inputs) after adjusting the offset on your Galil Controller, the amplifier may be damaged. Replace the amplifier to solve this problem.
