Product Description

ES-D508 Series Closed-loop Stepper Drive + Motor System

(Drive+ Motor/Encoder: ES-D508 + ES-M32320)

 

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 ES-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 ESD stepper drives is optimised - changing based on load position.

 

FEATURES

  • No tuning required and easy to use
  • Close-loop control eliminating loss of steps
  • Stepper drive supply voltage from 20 to 50 Vdc with peak current of 8.0A
  • Programming with RS232
  • Broader operating range – higher torque and higher speed
  • Reduced motor heating and more efficient smooth motion and super-low motor noise
  • Do not need a high torque margin
  • Fast response, no delay and almost no settle time
  • High torque at starting and low speed, high stiffness at standstill
  • Matched 3-phase NEMA 23 motors with 0.9Nm or 2Nm holding torque
  • Internal optical encoder (1000 lines) for accurate position control
