Page 2: Specifications
BLD-510S BLDC Driver Introduction This brushless motor driver is a driver independently developed by STEPPERONLINE to cooperate with the field of modern industrial automatic control. It mainly uses high-performance dedicated brushless DC motor driver chips, which have high integration, small size, complete protection, simple and clear wiring, and high reliability. The driver is suitable for driving small and medium-sized brushless DC motors with a rated power below 200W. - Page 3 BLD-510S BLDC Driver 2.3 Mechanical Specification (Unit: mm [1inch=25.4mm]) 2.4 Safety Precautions This product is professional electrical equipment and should be installed, debugged, operated and maintained by professional and technical personnel. Improper use will cause electric shock, fire, explosion and other dangers.

Page 8: Communication Method
BLD-510S BLDC Driver 5. Communication Method The communication mode uses the standard Modbus protocol, which complies with the national standard GB/T 19582.1-2008. It uses a dual-line serial communication based on RS485, and the physical interface adopts a conventional 3-pin 2.54 wiring terminal (A+, GND, B-) which is easy to connect in series. The transmission mode is RTU, and the verification mode is CRC, with the CRC starting word being FFFFH. - Page 9 BLD-510S BLDC Driver Addre Name Setting Range Defau First byte: Bit0: EN Bit1: FR Bit2: BK First byte: control bit state Bit3: NW NW=1: 485 control start stop speed regulation, $8000 Second byte: Hall angle NW=0: External IO control and number of pole pairs...
