Product Description

1.Introduction

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.

Component features:

• Step & Direction (PUL/DIR) or CW/CCW (double pulse) control
• Supply voltage: 20-80VDC
• Output current: 0.5-7.0A via software or 1.4-7.0A via DIP switches
• Max pulse input frequency: 200kHz
• 5V / 24V control signal voltage setting by DIP switch, default is 24V
• 16 microstep settings of 200-51.200 via software or 200-25.600 via DIP switches
• Configurable control command smoothing time to reduce motor vibration
• Automatic idle current reduction to 50% or 90% via SW4
• Convenient self-test for easy diagnosis
• 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 and Brake output
• Over-voltage and over-current protections
• Compatible with ND/M/DM series
• Performance improved by 10%-25%
• CE certified and RoHS compliant
