Technical Information
What is a Stepper Motor and Driver?
A stepper motor is designed for precise control of speed and position, operating step by step at fixed angles. This eliminates accumulated error, making it ideal for open-loop control systems. The driver converts pulse signals from the controller into power signals for the motor.
Subdivision Drive Benefits
Improved control precision by reducing step angles
Significant reduction in motor vibration and low-frequency oscillation
Increased output torque with reduced torque ripple
Troubleshooting: Motor Only Runs in One Direction
Check direction signal strength and wiring polarity
Verify signal voltage compatibility to prevent component damage
Ensure pulse mode matches between controller and driver settings
