Feature: 1. Reliable Working: Using 32 bit DSP technology and optical isolation differential signal input, the stepper motor driver has ultra low vibration noise. 2. Microstep Design: Built in 500 times frequency high subdivision, greatly improving balance and noise under low subdivision. The subdivision setting range is 2-128, 2.5-50. 3. Easy Setting: The current setting can be arbitrarily selected between rated values, and the current automatically halves when stationary. The pulse response frequency can get up to 200KHz. 4. High in Safety: Equipped with overvoltage protection, undervoltage protection, short circuit protection and other protection functions, offline input ENA protection function, alarm output function I/O port. 5. Great Efficiency: The driver integrates automatic parameter tuning function internally, which can automatically adjust the optimal operating parameters for different motors, maximizing the performance of the motor.
