EM806 Digital Stepper Driver with Stall Detection

By implementing advanced DSP current control algorithm, Leadshine EM806 is a advanced high performance 2-phase digital stepper drive. It takes step & direction control commands, and is very simple to implement in OEM applications.

Without an external sensor such as an encoder, the EM806 stepper drive can automatically identify 100% of stall of driven motors at 300 RPM or above, and send fault signals back to motion controller or other devices The EM806 stepper drive also adopts advanced features like electrical damping, anti-resonance, start-up smoothing, multi-stepping... With the input voltage of 20 - 80 VDC and output current of 0.5 - 8.2A, 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 EM806 stepper drive is easy to setup and configure via DIP switches. There are 15 resolution settings from 400 - 25600, and 7 output current settings from 2.7 - 8.2. 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 the EM806 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 EM806 will automatically load the pre-setting optimized settings for best performance.

For driving a non-Leadshine stepper motor, a user can use the 'Motor Auto Identification and Configuration' feature of the EM806 to get optimized performance.

For advanced users, 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 0.5 - 8.2A (increased by 0.1A); and idle current of 1-100% of output current.
