Y Series Closed Loop Stepper Driver 0-8.5A 20-80VAC/30-110VDC for Nema 34 Stepper Motor

This Y Series closed loop stepper driver 0-8.5A 20-80VAC/30-110VDC for Nema 34 stepper motor. Using a new generation of 32-bit DSP control technology and power angle, vector control technology, the maximum speed can reach more than 3000rpm. And the high-speed torque attenuation is much lower than that of the ordinary open-loop driver, which can greatly improve the high-speed performance and torque utilization rate of the stepping motor, thereby improving the processing efficiency and accuracy of the machine. Load-based current control technology can effectively reduce motor heating and extend motor life. The built-in alarm output signal of the driver is convenient for monitoring and control by the host computer. The position error alarm function ensures the safe operation of the processing equipment.
