1. Overview

DS860H is a two-phase digital stepper driver with serial port debugging function newly launched by Gree IoT Technology Co., Ltd. It adopts the latest 32-bit DSP control technology and integrates MODBUS-RTU standard protocol specifications. Users can set multiple parameters such as subdivision and working mode within 200-40000 through the upper computer debugging software, greatly enriching the practical functions of the product and meeting the application needs of most occasions.

The DS860H driver adopts a servo like control principle, integrating vector control technology, built-in micro segmentation technology, and adaptive filtering technology, greatly optimizing the performance of the stepper motor. It runs smoothly at low, medium, and high speeds with low noise. The precise and smooth pure sine current vector control technology effectively reduces motor heating.

The driving voltage range of DS860H driver is AC20V~80V, suitable for two-phase hybrid stepper motors with peak current below 7.2A and outer diameter of 57-110mm.
