Descriptions
Leadshine’s iES-2320 integrated easy servo motor is a NEMA 23 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-2320 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-2320 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-2320 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.
