Description
By taking direct 110 / 120 or 220 / 230 VAC input, Leadshine ES-DH series high voltage easy servo
drives can power large NEMA 34 and 42 easy servo motors and offer huge torque to applications with
motion control systems.
Leadshine ES-DH series easy servo drives are based on the latest DSP technology and Leadshine's
advanced control algorithm of combing brushless servo and stepper systems. They are featured with
closed position loop, offering huge torque, excellent acceleration & quick response, no torque
reservation, high standstill stiffness, extra low noise & heating, smooth motor movement, no hunting,
no overshooting for almost zero settling time, and no tuning for almost all applications.

Applications
Due to combining the features of both brushless servo drives and stepper drives, Leadshine ES-DH
series easy servo drives are suitable for both upgrading conventional stepper systems, and replacing
brushless servo systems which have closed loop and high torque requirements.
Leadshine ES-DH series easy servo drives can also be implemented as high performance open loop
stepper drives with direct 110 / 120 and / or 220 /230 VAC input.
Leadshine ES-DH easy servo drives and matching easy servo motors have been successfully
implemented by many OEM clients in applications such as CNC routers, plasma, milling machines,
engravers, packaging machines, printing equipments.
