   • Service robots with reliable motor performance

Key Guidelines:

1. Motor Specifications
   • Verify motor voltage and power parameters to ensure they are within the driver board's rated limits.
   • Exceeding specifications may cause permanent damage.
2. Hall Sensor Compatibility
   • Compatible with three-phase brushless DC motors equipped with 120° Hall sensor alignment.
   • Incompatible with motors using other Hall sensor angles (e.g., 60° or 180°).
3. Braking Function
   • Regenerative Braking: Converts kinetic energy into electrical energy for recycling.
   • Prohibition: Do not test braking function with a regulated power supply to avoid damage.
4. 5V Output Port
   • Provides <300mA current for microcontroller control.
   • Ensure total load does not exceed this limit to prevent overloading.
5. Thermal & Insulation Management
   • Ensure proper insulation of power components to avoid short circuits.
   • Implement effective heat dissipation measures (e.g., heatsinks, cooling fans) for prolonged operation.
6. Safe Start Function
   • Behavior: Speed control remains locked after power-on until reset.
   • Unlock Method: Reset via speed control or braking function.

Port Definitions & Functions:

1. Control Port (Left side), 2.0 mm Hole Pitch5V — The control board internally outputs 5V and can provide an external current of less than 300 mA.

2EL — Brake control port. It uses a reactive - free linear braking method with an energy - recovery function.

            The braking is controlled by an analog voltage ranging from 0 to 5V. When the rotational speed is constant,

            the higher the braking voltage, the greater the braking force (ranging from 0 to 100%).

2M — Rotational speed signal output port. The pulse frequency is proportional to the motor's rotational speed

           (the pulse ratio is related to the motor).

2Z/F — Forward and reverse rotation control port. It features hard commutation. Connecting it to 5V or leaving

             it floating makes the motor rotate in one direction, while connecting it to GND makes the motor rotate in

             the other direction.

2VR — Rotational speed control port. Speed regulation is achieved by an analog voltage ranging from 0V to

            5V (0 - 2.5V), with linear speed adjustment from low to high. When an external PWM signal is used

            for speed regulation, it needs to share the same ground with the driver board.

GND — Internal ground of the control board.

4. Control Port (Right side), 2.0 mm Hole Pitch

GND — Internal ground of the control board.

1VR — Rotational speed control port. Speed regulation is carried out by analog voltage from 0V to 5V (0 - 2.5V),

             with linear speed adjustment from low to high. When using an external PWM for speed regulation, it

             needs to share the same ground with the driver board.

1Z/F — Forward and reverse rotation control port. It has hard - commutation. Connecting to 5V or leaving it

             floating makes the motor rotate in one direction, while connecting to GND makes the motor rotate

             in the other direction.

1M — Rotational speed signal output port. The pulse frequency is proportional to the motor's rotational

            speed (the pulse ratio is related to the motor).

1EL — Brake control port. It is a reactive - free linear brake with an energy - recovery function. The analog

            voltage for braking ranges from 0 - 5V. When the rotational speed is constant, the higher the braking

            voltage, the greater the braking force (ranging from 0 - 100%).

5V — The control board internally outputs 5V and can supply an external current of less than 300mA.

5. Hall Port (Right side), 2.0 mm Hole Pitch

5V - Positive pole of the Hall power supply

1Ha - One of the motor Hall signals

1Hb - One of the motor Hall signals

1Hc - One of the motor Hall signals

6. Power Port (Right side)

P+ — Positive pole of the DC power supply

1MC — One of the three - phase motor wires

1MB — One of the three - phase motor wires

1MA — One of the three - phase motor wires

3. Note that the motor wires should not be too long. If they are too long, signal interference problems may occur.

4. When operating with continuous large - current, heat - dissipation issues should be noted.
