The 485 bus-type open/closed-loop stepper driver is a newly launched digital hybrid hybrid stepper servo driver with serial port debugging function. It integrates the MODBUS-RTU standard protocol specification, and the communication network port adopts a standard RJ45 interface. Users can set various parameters such as subdivision, current, speed, and working mode through the upper computer debugging software, which greatly enriches the practical functions of the product and can meet the application needs of most occasions. The 485 bus-type open/closed-loop stepper driver adopts servo-like control principles, combining the dual advantages of open-loop stepper and servo systems. It uses the latest 32-bit DSP control technology, which greatly improves the performance of the stepper system. It has excellent stability and ultra-low noise at medium and low speeds, and the high-speed torque has also been greatly improved, expanding the speed application range of stepper motors. The smooth and precise pure sine current vector control technology effectively reduces motor heat generation. Moreover, it has strong compatibility and high cost performance, and can meet the application needs of most occasions.

The integrated pulse-type stepper motor is a new motor-driver integrated actuator newly launched by GRMOT Technology Co., Ltd. It adopts the latest dedicated motor control digital signal processor, which enhances the motor's overall performance, reduces its heat generation and minimizes vibration. The integrated design of the motor and driver ensures a more compact installation and reduces external interference. This integrated motor comes with a serial port debugging function and uses a MINI USB interface for communication. Users can set various parameters such as subdivision, current and working mode through the upper computer debugging software, greatly enriching the product's practical functions and enabling it to meet the application needs of most occasions.
