CS-D808 Closed Loop Stepper Drive User Manual
Page | 1
1. Introduction
Leadshine CS-D808 is a closed loop stepper drive designed to solve the loss of step problem in open loop stepper
control systems, thus increase system reliability at minimal cost increase. It implements advanced control algorithm of
Leadshine based on its tens of years’ experience in stepper and servo controls. The CS-D808 is highly reliable and
affordable and performs excellent in many industrial applications such as CNC, medical, electronics, packaging...
The CS-D808 can power 2-phase NEMA 34 stepper motors with incremental encoders. Compared with traditional
open loop stepper systems, a CS-D808 adopted closed loop step system can eliminate potential loss of step, make
real-time position error correction, and do not need torque reservation (100% torque implementation). Also it can
power the driven stepper motor with reduced heating, lower noise, low vibration…
1.1 Features

1.2 Applications
When a CS-D808 closed loop stepper drive is implemented with a compatible stepper motor with encoder, the closed
stepper system can be adopted in many small to median 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.
