Key Specifications
- Input Voltage: DC 9V – 36V
- Current: 3A continuous
- Sensor Type: Hall sensor
- Drive Modes: FOC (vector) / Square Wave — freely switchable
- Control Loops: Position, Speed & Torque (three closed-loop)
- Control Interfaces: RS-485 Modbus RTU, Potentiometer, Analog voltage, PWM, Pulse, RC/Aircraft signal, Frequency
Main Functions
1. Position Control
- Pulse Position Servo: Same principle as stepper/AC servo — one pulse = one step.
- RS-485 Modbus RTU: Send position targets via communication bus; motor automatically navigates to the designated position.
- Potentiometer / Analog: Rotate a pot or adjust analog voltage to set motor position.
- Switch Position: Each switch input maps to a preset position; trigger = auto-run.
- RC/PWM/Frequency: Use pulse width, PWM duty cycle, or frequency to command position.
2. Speed Control
- Potentiometer / Analog: Adjust pot or analog voltage to set target RPM.
- RS-485 Modbus RTU: Send speed commands; controller holds stable at target speed.
- Switch Speed: Map multiple preset speeds to switch inputs.
- RC Signal: Control speed and direction via RC pulse width.
- PWM / Frequency / Pulse: Fine-tune speed via duty cycle, frequency, or pulse count.
3. Torque Control
- Potentiometer, analog voltage, RS-485, switch inputs, or PWM/frequency/pulse — all supported for torque target setting.
- Four-quadrant drive capability: generates braking force opposite to rotation — ideal for downhill conveyors or lift applications without stalling.
4. User Programming (Custom Control Logic)
Use the included PC programming software to perform secondary development. Freely switch between position/speed/torque modes and implement custom control logic. Supports assignment, jump, operation, and interrupt instructions. Includes 5 programmable input ports and 1 programmable 3.3V output port. Free engineering case source code provided (C++ Builder, MCU C language Modbus RTU).
5. Additional Features
- Phase sequence learning — connect three-phase and Hall lines in any order
- Positive / negative rotation limits
- Long-duration stall torque output; reverse torque supported
- Travel learning; power-on reset to origin; power-on travel learning
- Power-down position memory
- Commutation pulse output, fault alarm, position-complete, torque-up, and stop signal outputs
- Shutdown phase-lock function (motor lock); adjustable phase-lock current
- Three analog voltage detection channels (0 mV – 10,000 mV range, freely configurable)
- Free PC debugging & configuration software
6. Protection Features
- Reverse polarity, over-voltage & under-voltage protection
- Stall, over-current & overload protection
- Abnormal phase sequence & communication-interruption protection

Frequently Asked Questions
Q: What drive modes does this brushless motor controller support?
A: The board supports both FOC (Field-Oriented Control / vector) and square-wave drive modes, which can be freely switched at any time. FOC provides smoother, more efficient motor operation, while square-wave mode is simpler and suitable for less demanding applications.
Q: What communication interfaces are available for controlling this drive board?
A: The controller supports a wide range of interfaces including RS-485 Modbus RTU serial communication, potentiometer, analog voltage (0–10V), PWM, pulse, RC/aircraft model signal, and frequency input — making it compatible with PLCs, microcontrollers, RC receivers, and PC-based systems.
Q: Can this board be used for lifting or downhill conveyor applications?
A: Yes. The four-quadrant drive architecture allows the board to generate braking torque in the direction opposite to rotation, preventing runaway in downhill or load-lowering scenarios without stalling the motor.
Q: Is custom programming supported, and is software included?
A: Yes — the board supports secondary development via the included PC configuration and debugging software. Users can write custom control logic with support for assignment, jump, operation, and interrupt instructions. Free source code examples for C++ and MCU C language Modbus RTU are also provided at no extra cost.
