The EM542S 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, easy self-test, etc.


The EM542S is able to power 2 phase and 4 phase stepper motors smoothly with very low motor heating & noise. It can take 20-50VDC supply voltage and output 1.0 to 4.2A current. Its control type (step & direction or CW/CCW) and command smooth filtering time can be easily configured via DIP switches. Therefore, the EM542S is an ideal choice for many applications requiring simple step & direction or CW/CCW control of NEMA 17, 23, and 24 stepper motors.
