EM402 Digital Stepper Driver with Stall Detection
The EM402 is an advanced stepper motor driver with features including electrical damping, anti-resonance, start-up smoothing, multi-stepping and sensorless stall detection. 20 to 40 VDC powered with output current up to 2.2 A peak.
By implementing advanced DSP current control algorithm, Leadshine EM402 is a advanced high performance 2-phase digital stepper drive. It takes step & direction control commands, and is very simple to implement in applications.
Without an external sensor such as an encoder, the EM402 stepper drive can automatically identify the stall of driven motors at 300 RPM or above, and send fault signals back to motion controller or other devices The EM402 stepper drive also adopts advanced features like electrical damping, anti-resonance, start-up smoothing, multi-stepping. It is capable of driving a wide range of 2-phase stepper motors with high precision at extra smoothness, quietness, and very low motor heating. Its Multi-Stepping feature allows a low resolution step input to produce a much higher microstep output for smoother & quiet motor movement, and much lower motor heating. This will significantly improve the performance of your stepper control systems.
The EM402 stepper drive is easy to setup and configure via DIP switches. There are 3 resolution settings from 400 to 1600, and 3 output current settings from 0.70 to 2.20. Also, a user can simply set the idle current to full (100%) or 50% of the output current via a DIP switch. Its motor auto identification and drive self-configuration feature allows quick and easy setup for various motors at optimal performance.
Leadshine also offers matched stepper motors for EM402 with their optimized configurations stored in the stepper drive. The user only needs to use the motor rotary switch to select the right motor, and the EM402 will automatically load the pre-setting optimized settings for best performance.
For driving a non-Leadshine stepper motor, user can use the 'Motor Auto Identification and Configuration' feature of the EM402 to get optimized performance.
For advanced use, Leadshine offers tuning software for performance fine-tuning. The user can tune a stepper motor's three resonance areas (usually around 1 rps, 2 rps, and 4 rps) to reduce noise and vibration, set microstep resolution to any value from 200 to 104,000 (increase by 200), and configure output current to any value of 0.30 to 2.20A (increased by 0.1A); and idle current of 1-100% of output current.
