True servo performance based on stepper technology, without the traditional issues of resonance, heating, and loss of step, inherent in conventional stepper systems. The CMMS-ST controller differentiates itself from conventional controllers by eliminating resonance, heating and loss of step – performance issues inherent in stepper motor systems. The CMMS-ST controller's "true" closed loop performance makes the controller an ideal replacement for servo systems where high speed dynamics are not required.
