Technical Support & FAQs
What is a Stepper Motor and Driver?
Stepper motors are precision control motors that rotate in fixed angular steps, making them ideal for applications requiring accurate positioning without accumulated error. The SWT-203M driver converts controller pulse signals into motor power signals, enabling precise speed control and positioning.
Subdivision Drive Benefits
Subdivision technology reduces step angles for improved control precision, eliminates low-frequency vibration, and increases output torque while reducing torque ripple.
Troubleshooting: Motor Only Runs in One Direction
- Check direction signal strength and wiring polarity
- Verify signal voltage compatibility
- Ensure pulse mode matches driver settings (pulse/direction vs CW/CCW)
Important Note: When using this driver, ensure DIP switch 6 is set to the OFF position (SW6=1) for proper operation.
