1 Introduction
1.1 Product Introduction
iCS series is stepper motor integrated 14-bit absolute magnetic encoder and drive to solve the loss of step problems 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. At very compact size and with all
components integrated, the iCS can save mounting space, eliminate encoder connection & motor wiring time, reduce
interference, and cut/reduce cable and labor costs.
The iCS series is reliable and affordable and performs excellent in many industrial applications such as CNC, 3D printer, stage
equipment, medical, electronics, packaging...etc.
1.2 Features
No loss of step & no torque reservation & no hunting or overshooting & no tuning for easy setup
Enhance performance, especially at low speed application (<60RPM)
Soft-start with no "jump" when powered on
Low noise and vibration, smooth motion
Step&direction and CW&CCW control
3 digital inputs, 1 optically isolated digital output
14-bit single-turn absolute encoder
RS232 communication for Leadshine software connection
Over voltage, over current, position following error protections, etc.
1.3 Applications
The iCS series can be adopted in many low to median speed applications such as 3D printer, lab automation instruments,
plotters, medical equipment, electronic equipment, small packaging machines, etc.
