CS1-D507S & CS1-D503S Closed Loop Stepper Drive User Manual
Page | 1
1. Introduction
Leadshine CS1-D507S & CS1-D503S are closed loop stepper drives 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 CS1-D507S &
CS1-D503S are highly reliable and affordable and performs excellent in many industrial applications such as CNC,
medical, electronics, packaging...
The CS1-D507S & CS1-D503S can power 2-phase NEMA 8, 11, 14, 17, 23, and 24 stepper motors with incremental
encoders. Compared with traditional open loop stepper systems, the CS1-D507S & CS1-D503S 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…
