EM Stepper Drives

High performance, Open-loop, Current up to 8.2A
The Leadshine EM Series stepper drives (also known as miscrostepping drives) provide precise, smooth, and reliable motion control for modern automation systems. Designed from over 20 years of stepper drive experience, they combine advanced control technology with simplicity, high reliability, and low noise operation. The EM Series stepper drives can be paired with 2-phase (1.8°) and 4-phase (0.9°) motors, in NEMA size 8, 11, 15, 17, 23, 34, and 42, offering flexible control for a wide variety of applications.
The CANOpen models (EM522-CAN & EM556-CAN) support the CANOpen standard protocol DS301 V4.02 and DSP402 V2.01, providing enhanced reliability, super-low stepper noise, anti-resonance, and low-speed ripple smoothing. With CANopen, these drives support operating modes including Profile Position (PP), Profile Velocity (PV), Homing (HM), and can form CANOpen networks up to 127 nodes, making them ideal for fieldbus applications that demand high reliability and superior performance.
Key Features
- Step & Direction (PUL/DIR) or CW/CCW control
- 200 kHz maximum pulse input frequency (500 kHz optional)
- 16 microstep resolutions (200–25,600 via DIP switches; up to 51,200 via software)
- Configurable command smoothing for reduced vibration
- Idle current reduction (50% or 90%)
- Convenient self-test and auto-tuning for wide-range motors
- Anti-resonance for optimal torque, smooth motion, and low heating/noise
- Soft-start without motor “jump” at power-on
- Optically isolated inputs (5V or 24V)
- Fault and brake output
- Over-voltage and over-current protection
- CE certified and RoHS compliant
Applications:
EM Series drives are ideal for CNC machines, packaging systems, laboratory automation, semiconductor equipment, and other applications requiring reliable, high-precision stepper motor control.
