Y Series Modbus RS485 Closed Loop Stepper Driver 0-5.0A 20-50VDC for Nema 17, 23, 24 Stepper Motor

This is a closed-loop stepper driver support standard Modbus RTU protocol. It delivers superior performance with a current range of 0–5.0A and an operating voltage of 20–50VDC, making it ideal for Nema 17, 23, 24 stepper motors.
The next-generation 32-bit DSP-based closed-loop stepper driver combines high performance, stability, and cost efficiency with ultra-low noise and vibration. With versatile I/O interfaces, it supports position/speed control, homing, and single-axis motion functions, while allowing users to adjust current, subdivision settings, and monitor real-time motor status via bus commands.

Key Features

• Next-generation 32-bit DSP technology delivers exceptional cost-performance ratio, superior stability, and ultra-quiet operation with minimal vibration
