Descriptions
ES-D508 is one of the models in Leadshine ES-D series easy servo drives which can take 20-45 VDC operating voltage
and output 0.5 - 8.0 A continuous load-based current. It is capable of driving NEMA 17, 23, 24 and 34 (1-2 stacks)
easy servo motors (stepper motors with encoders) with the position loop closed in real time.
Based on latest DSP technology and adopting Leadshine's advanced control algorithm, ES-D508 easy servo drive
applies servo control on easy servo motors. When adopted with an easy servo motor, it combines features of both
open loop steppers & brushless servo systems, and offers many unique advances features for excellent motion
control system performance.
When an ES-D508 easy servo drive is implemented with a Leadshine ES-M series easy servo motor, there is No
Configuration Needed for almost all applications. The factory setting of the resolution is 4000 pulses per revolution
(equal to 20 microstep in 2-phase stepper systems). With Leadshine configuration software, ProTuner, an advanced
user can also set custom settings of resolution, current & position loop parameters, idle current percentage, etc.

Applications
With many unique advanced features, Leadshine ES-D508 easy servo systems are ideal for many industries to
upgrade stepper performance or replace brushless servo systems in many applications.
Leadshine OEM clients have successfully implemented ES-D508 driven easy servo systems in applications such as
desktop CNC routers, small CNC mills, laser cutters / engravers, dental mills, electronic assembly & inspection
equipments, labeling equipments, pick & place machines, X-Y tables, scientific instruments.
