1. Introduction
The EM882S is a new digital stepper dr
ive based on Leadshine’s widely im
plemented DM stepper drives (10+ millions
of units in field). While retaining features of simple design, easy setup, high precision and reliability, Leadshine has
also upgraded it by adopting the latest stepper control technology and added additional advanced features for better
torque (10-25%), quicker response time, control command smoothing, motor selector, etc.
The EM882S is able to power 2 phase (1.8°) and 4 phase (0.9°) stepper motors smoothly with very low motor heating
& noise. It can take 20-80VDC supply voltage and output 0.5 to 8.2A current. All the micro step, output current
configurations and motor model selection can be easily done via built in DIP switches. Therefore, the EM882S is an
ideal choice for many applications requiring simple step & direction or CW/CCW control of NEMA 23, 24 and 34
stepper motors.

1.2 Applications
The EM882S stepper drive is designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA23, 24 and 34 hybrid stepper
motors. It can be adopted in many industries (CNC machinery
, electronics, medical, automation, packaging…) for
applications such as CNC routers, mills, plasma, laser cutters, factory assembly lines, vending machines, etc. Its
excellent performance, simple design, and easy setup features make EM882S ideal for many step & direction control
type applications.
