Makerbase MKSESC 84200HP VESC Instruction Manual

1. Introduction

The Makerbase MKSESC 84200HP is a high-performance Electronic Speed Controller (ESC) designed for demanding applications such as E-Foils, Fight Robots, Surfboards, and AGV Robots. It features a robust design with an aluminum alloy shell for enhanced heat dissipation and protection.

This ESC incorporates a three-phase splitter and an adjustable Current/Voltage filter. It utilizes an ultra-precision bidirectional current detection amplifier (INA241A) for accurate phase line current sampling, ensuring reliable motor data detection. A built-in Bluetooth module allows for convenient configuration, monitoring, and control via the VESC TOOL on both PC and mobile devices.

2. Safety Warnings and Precautions

• WARNING: Do not connect or disconnect interface devices (USB, encoder, etc.) or power-related components (motor, power supply, etc.) while the system is powered on. This may cause electrical surges or short circuits, potentially damaging the motherboard.
• ADC Signal Note: The ADC interface can only accept 3.3V signals, not 5V signals. When connecting a throttle handle to the ADC interface, ensure the positive pole of the power supply is connected to 3.3V, not 5V.
• AUX Function Note: The AUX function interface of the MKSESC 84200HP is temporarily unavailable. Do not connect the SIG pin to the battery control terminal.
• For enhanced heat dissipation, a generous application of thermal grease is used during assembly. You may notice some thermal grease around the housing seams. This is normal and will not impact the product's performance or safety.

Key Connections:

• BATTERY: Connect your battery to the BAT+ (red) and BAT- (black) terminals.
• MOTOR: Connect the three motor phase wires (A, B, C) to the corresponding terminals.
• ANTENNA: Connect the Bluetooth antenna for wireless communication.
• USB: Use the Type-C USB port for PC connection and configuration.
• PPM: For RC servo control signals.
• CAN: For CAN bus communication.
• SWD: For debugging and firmware updates.
• COMM: Communication interface for various peripherals.
• AUX: (Currently unavailable, do not connect SIG pin to battery control terminal).
• SENSE: For sensor input (e.g., Hall sensors, AS5047, AS5048A).

Switches:

• VCC Switch: Selectable sensor interface VCC voltage.
• DC-DC Switch:
  • KEEP ENABLE: Maintains power-on mode; the power supply is not controlled by the 'Shutdown' pin.
  • SHUTDOWN: Enables 'Shutdown' control mode; the power supply can be started and shut down through the motor and the 'Power Switch' pin.

4. Operating Instructions

4.1 Software Configuration

The MKSESC 84200HP can be configured and monitored using the VESC TOOL software. This tool is available for both PC and mobile devices (via the built-in Bluetooth module).

For detailed step-by-step lessons on software configuration and usage, please refer to the official Makerbase GitHub repository and YouTube channel:

4.2 Basic Motor Control (Demonstration)

Once configured, you can control the motor using the VESC TOOL. The demonstration video below illustrates basic forward and reverse motor control.

In the VESC TOOL interface, you will typically find 'FWD' (Forward) and 'REV' (Reverse) buttons to control the motor's direction.

5. Maintenance

The MKSESC 84200HP is designed for durability and performance. Its aluminum alloy shell serves to increase heat dissipation and extend the service life of the ESC, while also providing effective protection against foreign objects.

Regularly inspect all wiring connections for wear or damage. Keep the unit clean and free from dust and debris. Ensure that the operating environment allows for adequate heat dissipation, especially during high-current operation.

6. Troubleshooting

If you encounter issues with your MKSESC 84200HP, consider the following:

• No Power/No Response: Check all power connections, including battery and main power switch. Ensure the DC-DC switch is set correctly (KEEP ENABLE or SHUTDOWN with external switch).
• Motor Not Spinning: Verify motor phase wire connections. Check sensor connections if using sensored mode. Ensure the VESC TOOL configuration is correct for your motor type (BLDC, FOC, etc.).
• Incorrect Motor Direction: Use the FWD/REV buttons in the VESC TOOL to test and adjust motor direction.
• ADC Input Issues: Double-check that any throttle or analog input connected to the ADC interface is providing a 3.3V signal, not 5V, as specified in the warnings.
• Communication Problems: Ensure the USB cable is securely connected or the Bluetooth module is paired correctly with your mobile device. Check VESC TOOL firmware compatibility.
• Over-current/Over-voltage Protection: If the ESC shuts down unexpectedly, check for potential short circuits, motor stalls, or battery voltage exceeding the specified range (14V-84V).
