The S-123H 3BHB030479R0512 is a high performance stepper driver from ABB with the following features:

Suitable motor: The driver is suitable for driving any two-phase or four-phase hybrid stepper motor below 2.0A or 3.5A phase current.

Features: With a single power supply, optical isolation input, subdivision precision optional features.

Subdivision function: Step Angle subdivision function can make the motor run smoother, reduce vibration and noise, improve accuracy, users can easily set the subdivision accuracy, up to 128 subdivisions (25600 steps/turn).

Automatic current reduction: with static automatic current reduction function, when the motor stops, the output current automatically reduces, reducing the heat of the motor and the driver.

Dip switch: The driver side is equipped with eight-bit dip switch group, the user can easily set the dynamic operating current (total 8 levels), static current reduction and subdivision accuracy.

Input voltage: can accept AC input (10-29VAC) or DC input (12-42VDC).

Control and protection: with start-stop and steering control, over current, over voltage, overload and other protection functions.

Speed regulation and braking: Support external analog speed regulation, braking quick stop.

Signal output: with fault alarm output and speed signal output function.

Sensor compatibility: Suitable for motor drives with position sensor (Hall) signal output.

Designed with a focus on performance and user convenience, this drive is suitable for industrial applications that require high precision and reliability
