DC Servo Driver (RS485)

RS485 DC Servo Drivers for Networked OEM Motion

Runcin RS485 DC servo drivers provide compact motion control for low-voltage automation systems. The series supports servo motors from 100W to 750W. Therefore, machine builders can select a suitable drive for compact instruments and higher-output motion axes.

These drivers combine a 32-bit DSP platform with optimized PID control. They manage position, speed and torque through full digital control. In addition, the RS485 interface supports Modbus RTU commands and single-axis motion functions. This structure simplifies communication with compatible PLCs, HMIs and industrial controllers.

RS485 Servo Control for 100W to 400W Motors

The RD-R 100/200/400 low-voltage DC servo driver matches 100W, 200W and 400W motors. It accepts DC 24–50V input and works with a 2500-line incremental encoder. Rated current options include 5A, 7A and 10A. Maximum output reaches 15A, 21A or 30A according to the selected power.

The compact housing measures 134 × 83 × 33mm. As a result, engineers can integrate the drive into machines with limited cabinet space.

750W Control and Application Selection

The RD-R750 low-voltage DC servo driver extends the RS485 range to 750W applications. It uses the same digital control approach and supports Modbus RTU communication. Therefore, it suits equipment that needs more motor output while retaining networked control and encoder feedback.

Typical applications include engraving, wire stripping, marking and cutting machines. The range also supports laser equipment, plotters, medical devices, CNC machine tools and automated assembly systems.

Before selecting a driver, confirm motor power, supply voltage, encoder type and current demand. Also review the Modbus RTU settings, controller compatibility and mechanical load.
