EM422S Stepper Drive
36VDC, 2.2A
As the next generation of DMD422 drive, the EM422S model is a newer 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, this drive is upgraded 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 EM422S stepper drive can power 2 phase (1.8°) and 4 phase (0.9°) stepper motors smoothly with very low motor heating & noise. It can take 18-36VDC supply voltage and output 0.3 to 2.2A current. Micro step, output current, control type (step & direction or CW/CCW) and self-test can be easily done via built in DIP switches. It is an ideal choice for many applications requiring simple step & direction or CW/CCW control of NEMA 8, 11, 14 and 17 stepper motors.
EM422S Stepper Drive Features
- Step & direction (PUL/DIR) or CW/CCW (double pulse) control
- 18-36VDC supply voltage
- 70 KHz max pulse input frequency
- 8 micro step settings of 200-25,600 via DIP switches, or 200-51,200 via software (increase by 200)
- 8 output current settings of 0.3 – 2.2A via DIP Switches, or via software (increase by 0.1)
- Configurable control command smoothing for reducing motor vibration
- Automatic idle current reduction to 50%
- Convenient self-test for easy diagnosis
- Automatic self-configuration to match wide-range NEMA 8, 11, 14 and 17 stepper motors
- Anti-Resonance for optimal torque, extra smooth motion, low motor heating and noise
- Soft-start with no “jump” when powered on
- Optically isolated inputs
- Fault output
- Over-voltage and over-current protections
- CE certified and RoHS compliant
Typical Applications
The EM422S stepper drive is designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA 8, 11, 14 and 17 hybrid stepper motors or Permanent magnetic stepper motor (7.5° or 15°). It can be adopted in many industries (CNC machinery, electronics, medical, automation, packaging…) for applications such as 3D printer, automation machines, medical machines, laser cutters, X-Y tables, labeling machines, pick-place devices, etc. Its excellent performance, simple design, and easy setup features make EM422S ideal for many step & direction control type applications.
