The CAN open bus open-loop stepper driver is a stepper motor driver based on the CAN open communication protocol. It can achieve open-loop control of the stepper motor, that is, without the need for position feedback mechanism, it directly drives the motor to rotate based on input control signals (such as pulse signals, direction signals, etc.). The following is a detailed introduction to the CAN open bus open-loop stepper driver:


Technical features

CAN open communication protocol: CAN open is a standard for distributed industrial control technology based on CAN bus (Controller Area Network), jointly developed by manufacturers and users, with high flexibility and scalability. The CAN open protocol supports multiple device types and communication methods, which can meet the needs of different industrial applications.

Open loop control: The CAN open bus open-loop stepper driver adopts an open-loop control method, which does not require additional position feedback devices (such as encoders, sensors, etc.), reducing system costs and complexity. However, it should be noted that open-loop control may not achieve the same high position accuracy and stability as closed-loop control.

High performance: Despite being an open-loop control, CAN open bus open-loop stepper drivers typically have high-performance drive circuits and control algorithms, enabling high-speed and high-precision stepper motor control.
