IO Control Stepper Driver (2 Phase)

2-Phase I/O Stepper Drivers for Standalone Automation

Runcin 2-phase I/O stepper drivers provide direct motor control without requiring a fieldbus network. The series includes five models for compact and higher-power stepper systems. Therefore, machine builders can select a driver according to motor frame, voltage, peak current and command method.

The range includes analog-input and switch-controlled versions. In addition, ARM control technology and PID parameter auto-tuning help each driver match different motors. These functions support smooth motion with reduced motor noise.

Analog and Switch-Controlled Driver Options

The R2D1725PS I/O stepper driver is designed for smaller 35, 39 and 42 series motors. It accepts DC 18–36V input and provides up to 2.5A peak current. Moreover, users can select preset speed and current levels through simple I/O signals.

For 57-frame systems, the R2D2342P analog stepper driver supports a 0–5V analog speed command, with a 0–10V option available. It accepts DC 20–50V and delivers up to 4.2A peak current. Meanwhile, the R2D2342PS driver supports direction-plus-pulse or dual-pulse modes.

Higher-Power Drivers for Larger Motors

The R2D3472P I/O stepper driver suits larger 86-frame motors. It supports DC 24–110V or AC 18–80V input and reaches 7.2A peak current. Its analog input allows speed adjustment from a potentiometer, PLC output or compatible controller.

Alternatively, the R2D3472PS driver provides the same voltage range and peak current while supporting selectable pulse control modes. Therefore, engineers can choose between analog speed control and digital pulse control within the same power class.

These drivers suit feeders, conveyors, packaging machines and cutting equipment. They also support electronic processing systems and automated assembly stations.

Before selecting a model, compare motor current, supply voltage, control signal and speed range. Also confirm installation space and protection needs.
