By implementing advanced DSP current control algorithm, Leadshine EM503 is a advanced high performance 2-phase digital stepper drive. It takes step & direction or CW/CCW control commands, and is very simple to implement in applications.
Without an external sensor such as an encoder, the EM503 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 EM503 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 EM503 stepper drive is easy to setup and configure via DIP switches. 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 EM503 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 EM503 will automatically load the pre-setting optimized settings for best performance. For driving a non-Leadshine stepper motor, the user can use the 'Motor Auto Identification and Configuration' feature of the EM503 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 to 4.20 A and idle current of 1-100% of output current.
