The S-123H 3BHB030479R0512 High performance stepper driver  is a high-performance stepper driver produced by ABB. The following is an introduction to its functions and usage:

Feature

S-123H 3BHB030479R0512 High performance stepper driver Motor drive capability: Suitable for driving any two-phase or four-phase hybrid stepper motor with 2.0A or 3.5A phase current below, providing a stable drive signal for the motor to ensure normal operation of the motor.

Multiple power supply options: AC input (10-29VAC) and DC input (12-42VDC) are acceptable. When using AC input, the user only needs to connect a transformer of dozens of watts, and there is no need to buy a self-made DC power supply, which saves cost and is convenient to use.

S-123H 3BHB030479R0512 High performance stepper driver Step Angle subdivision function: it can make the motor run smoothly, reduce vibration, reduce noise, and improve accuracy. The subdivision accuracy can be easily set by the user up to 128 subdivisions (25,600 steps/turn).

Static automatic current reduction function: When the motor is stopped, the output current can be automatically reduced to a lower value, thereby reducing the heat of the motor and the driver, extending the service life of the equipment and reducing energy consumption.

Dip switch setting function: The driver side is equipped with a row of eight-bit dip switch group, the user can easily set the dynamic working current (a total of 8 levels), static current reduction and subdivision accuracy through the dip switch, convenient and flexible configuration according to actual needs.

Protection function: With over current, over voltage, overload and other protection functions, can effectively protect the drive and motor from abnormal damage, improve the stability and reliability of the system.

Other functions: Support external analog speed regulation, brake quick stop, fault alarm output, speed signal output and other functions, but also suitable for motor drive with position sensor (Hall) signal output, to meet the needs of a variety of application scenarios.

Usage method

Installation and connection: Install the driver in a position that is well ventilated, vibration-free, and away from strong electromagnetic interference sources. Connect the power supply, motor, and other related equipment according to the instructions. Pay attention to the correctness and firmness of the wiring to avoid equipment damage caused by incorrect wiring.

Parameter setting: According to the motor parameters used and the actual application requirements, the dynamic working current, static current reduction and subdivision accuracy of the driver are set through the dip switch. If you need to use functions such as external analog speed regulation and braking quick stop, you also need to connect the corresponding external devices and make relevant Settings.

Operation and monitoring: After the drive is powered on, the running state of the motor is monitored in real time, including speed, current, temperature and other parameters. If there are abnormal conditions, such as overcurrent, overvoltage, overload, etc., the driver will automatically trigger the protection function and output the fault alarm signal. In this case, you need to rectify the fault in a timely manner before restarting the drive.

Maintenance and maintenance: Regularly check the connection of the driver and the motor to ensure that the wiring is firm. Clean dust and debris from the driver surface to maintain good heat dissipation. If the driver or motor is found to have abnormal wear or damage, the relevant parts should be replaced in time to ensure the normal operation of the system.
