Servo Performance...Stepper Price! 

Servomode, a standard feature on all Copley Controls step motor drives, provides true servo performance based on stepper technology.  

Issues inherent in conventional stepper systems such as resonance, heating, and loss of step, are eliminated.  By actively controlling current through the step motor phases the motor is controlled as a high-pole-count Brushless servo. 

The result is an extremely affordable servo system.

 Copley offers easy-to-use and cost-effective solutions for single and multi-axis applications.
