EM870S Digital Stepper Drive (80VDC input, 7.0A)
Motion Control Products Ltd (MCP) newly launched EM870S digital stepper drive which is based on Leadshine’s widely implemented DM stepper drives. While retaining features of simple design, easy setup, high precision and reliability, it has been also upgraded by adopting the latest stepper control technology with additional advanced features for better torque (10-25%), quicker response time, control command smoothing and easy self-test, etc.
The EM870S digital 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 20-80VDC supply voltage and output 0.5 to 7.0A 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 EM870S is an ideal choice for many applications requiring simple step & direction or CW/CCW control of NEMA 23, NEMA24 and NEMA 34 stepper motors with up to 4.5Nm torque.
Features
- Step & direction (PUL/DIR) or CW/CCW (double pulse) control
- 20-80VDC supply voltage
- 200 KHz (500KHz optional) max pulse input frequency
- 16 microstep resolutions of 200-25,600 via DIP switches, or 200-51,200 via software (increase by 200)
- 8 output current settings of 1.4 -7.0A via DIP Switches, or 0.5-7.0A via software (increase by 0.1)
- Configurable control command smoothing for reducing motor vibration
- Idle current reduction to 50% or 90% selection via SW4
- Convenient self-test for easy diagnosis
- Auto-tuning to match wide-range NEMA 23, 24, 34 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 with 5V or 24V
- Fault and Brake output
- Over-voltage, over-current and motor cable error protections
- CE certified and RoHS compliant
Applications
The EM870S digital 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 used in many industries, such as CNC machinery, electronics, medical, automation and packaging. Its excellent performance, simple design, and easy setup features make EM870S ideal for many step & direction control type applications including CNC routers, mills, plasma, laser cutters, factory assembly lines, vending machines etc.
