12. Troubleshooting
- Controller does not power on:
- Check power supply voltage (DC 12-24V).
- Verify power connections for correct polarity and secure contact.
- Motor does not move:
- Ensure motor driver is powered and enabled.
- Check PUL, DIR, EN connections between controller and driver.
- Verify motor parameters (speed, pulse count) are set correctly and not zero.
- Check for active limit switch inputs that might be preventing movement.
- Incorrect motor direction:
- Reverse the DIR signal connection or adjust the direction setting in the controller.
- Display shows error:
- Refer to the Quick Start Guide for specific error codes and their meanings.
- Power cycle the device.
