Y Series Modbus RS485 Stepper Driver 0-4.0A 24-50VDC for Nema 23, 24, 34 Stepper Motor

This is a stepper driver support standard Modbus RTU protocol. It delivers superior performance with a current range of 0–4.0A and an operating voltage of 24–50VDC, making it ideal for Nema 23, 24, 34 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 control technology delivers exceptional cost-performance ratio, superior stability, and ultra-quiet operation with minimal vibration
