ABB S-123H 3BHB030479R0512 is a high-performance stepper driver with the following characteristics:
Driving Capability
It can drive two-phase or four-phase hybrid stepper motors with phase currents below 2.0A or 3.5A, offering a wide application range to meet the driving needs of various stepper motor specifications.
Power Supply Characteristics
Supports multiple power input modes, accepting both 10–29VAC alternating current and 12–42VDC direct current. When using AC input, only a tens-of-watt transformer is required, allowing users to flexibly choose the power supply method according to actual conditions, which saves costs and ensures convenient operation.
Functional Features

  • Step Angle Subdivision: The subdivision accuracy is optional, up to 128 subdivisions (25,600 steps/revolution), effectively improving motor operation smoothness, reducing vibration and noise, and enhancing motion control accuracy.

  • Automatic Current Reduction in Standby: When the motor stops, the output current automatically drops to a lower value, reducing heat generation of the motor and driver and extending equipment service life. This function can be flexibly enabled or disabled via DIP switches.

  • DIP Switch Configuration: An eight-bit DIP switch group on the driver's side allows users to easily set dynamic operating current (8 levels), static current reduction, and subdivision accuracy, featuring simple operation and easy configuration.

Protection Functions
Equipped with multiple protection functions such as overcurrent, overvoltage, and overload, it enables real-time monitoring during equipment operation. In case of abnormalities, it rapidly responds to protect the driver and motor from damage, improving system stability and reliability.
Application Scenarios
Suitable for motor drives with position sensor (Hall) signal output, it is widely used in industrial automation fields requiring high-precision position control, such as production line control and robot control, as well as in equipment with high requirements for motor control accuracy and stability.
