Product Description

ES-D808 Stepper Drive

30 -80 VDC Inputs | 8.0A peak

 

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-D series stepper drives is designed to be used alone or together with our M-series stepper motors as a closed-loop stepper system to overcome this weakness. By using high resolution encoders to update the motor position every 25 micro-seconds, our ES-D808 drive ensures controlled, real-time position accuracy without losing steps. Different from the constant current output of an open-loop stepper system, output current in ES-D stepper drives is optimised - changing based on load position.

Our CS-D closed-loop stepper drive system can be used to upgrade open loop stepper systems or replace some servo systems, especially in many small-and-medium-speed applications such as CNC routers, CNC mills, CNC laser cutters, CNC plasmas, lab automation instruments, plotters, medical equipment, electronic equipment, small packaging machines etc.
