Frequently Asked Questions
What is a stepper motor and stepper drive?
A stepper motor is designed for precise control of speed and position, operating step by step at fixed angles. Each pulse signal from the controller causes the motor to rotate a precise angle, making it ideal for open-loop control applications with no accumulated error.
What is drive subdivision?
Subdivision allows a motor's inherent step angle to be completed in multiple smaller steps, improving control precision and reducing vibration. This is particularly beneficial for applications requiring smooth operation and high positioning accuracy.
What are the advantages of subdivision drivers?
Subdivision drivers provide improved step uniformity, enhanced control accuracy, significant vibration reduction, elimination of low-frequency oscillation, and increased output torque with reduced torque ripple.
Why does my motor only work in one direction?
This may occur due to weak direction signals, incorrect wiring polarity, or mismatched pulse modes. Ensure the driver is set to match your controller's signal type (pulse/direction or CW/CCW).
