Description:
The EM882S 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, motor selector, etc.
The EM882S is able to 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 8.2A current. All the micro step, output current configurations and motor model selection can be easily done via built in DIP switches. Therefore, the EM882S is an ideal choice for many applications requiring simple step & direction or CW/CCW control of NEMA 23, 24 and 34 stepper motors.
Features:
• Step & direction (PUL/DIR) or CW/CCW (double pulse) control
• 20-80VDC supply voltage
• 200 KHz max pulse input frequency
• 16 microstep resolutions of 400-51,200 via DIP switches, or 200-51,200 via software (increase by 200)
• 8 output current settings of 2.1-8.2A via DIP Switches, or 0.5-8.2A via software (increase by 0.1)
• Configurable control command smoothing for reducing motor vibration
• Idle current reduction to 50% or 100% selection via SW4
• Sensor-less stall detection
• Auto-tuning and motor model selection to match wide-range stepper motors
• Anti-Resonance for optimal torque, extra smooth motion, low motor heating and noise
• Soft-start with no “jump” when powered on
• Fault output
• Over-voltage and over-current protections
Applications:
The EM882S 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 adopted in many industries (CNC machinery, electronics, medical, automation, packaging…) for applications such as CNC routers, mills, plasma, laser cutters, factory assembly lines, vending machines, etc. Its excellent performance, simple design, and easy setup features make EM882S ideal for many step & direction control type applications.
