CS-D508 Closed-loop Stepper Drive / Motor System 

(Drive+ Motor/Encoder: CS-D508 + CS-M Motors)

Traditional stepper motor drive systems operate open loop providing position control without feedback. However, because of this, loss of synchronisation can occur between commanded and actual steps. Monitoring position using an optical encoder can help but only highlights position loss rather than correcting it! An application requiring real-time, closed-loop performance throughout the move has previously required engineers to choose much higher cost/complexity servo systems which in many applications lack the high torque feature of stepper motors. Hence, expensive planetary gearboxes have to be added.

Our new CS-D508 series closed-loop stepper drives and motors system overcome this weakness by using high resolution encoders to update the motor position every 25 micro-seconds, ensuring controlled, real-time position accuracy without losing steps. Different from the constant current output of an open-loop stepper system, output current in CS-D stepper drives is optimised - changing based on load position.

DRIVE FEATURES

• No loss of step
• No torque reservation
• No hunting or overshooting
• No tuning for easy setup
• A configurable digital output for the option of Fault Output, In Position, or Brake Control
• Low noise and vibration, smooth motion
• Enhance performance at low speed application( <60RPM)
• 20-50VDC supply voltage, max 8A output current
• Max 200 KHz input frequency
• 15 micro step settings of 800-51,200 via DIP switches, or 200-51,200 via software (increase by 200)
• Protections for over voltage, over current and position following error
• CE certified and RoHS compliant
