The EM542S is a new versatile, digital stepper drive based on Leadshine's widely implemented DM stepper drives (10 millions + units in the 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 up to +50 VDC supply voltage and output 0.5 to 4.2 A current. All the micro step and output current configurations can be easily done via built in DIP switches. Its control type (step & direction or CW/ CCW) and command smooth filtering can also be 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, NEMA 23 and NEMA 24 stepper motors.
