Descriptions
Leadshine’s iES‐1706 integrated easy servo motor is a NEMA 17 stepper motor integrated with a 1,000‐line (4,000
PPR) encoder and an easy servo drive. At very compact size and with all components integrated, the iES‐1706 can
save mounting space, eliminate encoder connection & motor wiring time, reduce interference, and cut/reduce cable
and labor costs.
By adopting Leadshine’s latest easy servo control technology, the easy servo drive of the iES‐1706 can drive the
stepper motor with high staring torque, high precision, smooth movement, and extra low noise at low speed
movement with no obvious resonance area. Different from constant‐output‐current output from a drive to a stepper
motor in normal open‐loop stepper controls, output current of the iES‐1706 is dynamic and changes depending on
load condition, same as servo controls. Therefore, it can significantly reduce motor heating and increase motor
lifetime. The drive takes step & direction input commands, and is capable of outputting in‐position and fault signals
back to a motion controller or external devices, for complete system controls.
