The EM882S is a new digital stepper drive based on Leadshine’s widely implemented 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, alarm and brake output, etc.

The EM882S is able to power 2 phase and 4 phase stepper motors smoothly with very low motor heating & noise. It can take 20-80VDC supply voltage and output 0.5 to 8.2A current. Its control type (step & direction or CW/CCW) and command smooth filtering can also be configured via Leadshine ProTuner. 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.
