FLIPSKY FSESC 75350 84V High Current 350A ESC User Manual

1. Introduction

This manual provides essential instructions for the safe and efficient use of the FLIPSKY FSESC 75350 84V High Current 350A Electronic Speed Controller (ESC). It is designed for applications such as e-foils, fighting robots, surfboards, and AGV robots. Please read all instructions carefully before installation and operation.

Important Safety Information

• Read all instructions before use. Improper use can lead to damage to the ESC, connected components, or personal injury.
• This device is intended for experienced users due to its high power capabilities.
• Ensure all connections are secure and correctly insulated to prevent short circuits.
• Always disconnect the power source before performing any maintenance or making connections.
• Firmware Warning: Phase filtering is not available for Flipsky ESC75100 and 75200. Please turn off the phase filter function and choose "false" in VESC_TOOL when using firmware version 5.3 or above (VESC_TOOL 3.01). Failure to turn off the phase filter will result in ESC damage. Do not restore the default parameters when using the wizard interface. It is recommended to keep firmware 5.2 from the factory; new firmware upgrades may damage the ESC.

• 1 x FSESC 75350 ESC Base On Vesc With Aluminum Case Water Cooling Enclosure

5. Setup

5.1 Physical Connections

Connect the ESC to your battery, motor, and control peripherals according to the diagrams below. Ensure correct polarity for battery connections and secure all motor phase wires.

5.2 Initial Configuration (Firmware)

The FLIPSKY FSESC 75350 is based on VESC technology and requires configuration using the VESC_TOOL software. It is crucial to follow these guidelines:

• Firmware Version: It is strongly recommended to keep the factory-shipped firmware version 5.2. Upgrading to newer firmware versions may cause damage to the ESC.
• Phase Filter: If you must use firmware version 5.3 or above (VESC_TOOL 3.01), you must disable the phase filter function. Set this option to "false" within the VESC_TOOL. Failure to do so will result in ESC damage.
• Default Parameters: Do not restore default parameters when using the VESC_TOOL wizard interface, as this may overwrite critical settings.

Refer to the official VESC documentation and community resources for detailed instructions on using VESC_TOOL for motor detection and parameter tuning.

6. Operation

Once configured, the FSESC 75350 provides precise control over your motor. The ESC supports various input sources and communication protocols for flexible integration:

• Input Sources: PPM (Pulse Position Modulation), ADC (Analog-to-Digital Converter), NRF (Nordic Radio Frequency), UART (Universal Asynchronous Receiver/Transmitter), PAS (Pedal Assist System).
• Communication Ports: USB (for VESC_TOOL connection), CAN (Controller Area Network for multi-ESC setups), UART, SPI (Serial Peripheral Interface), IIC (Inter-Integrated Circuit).

The ESC allows for configurable limits on RPM, current, voltage, and power to protect your system and ensure safe operation. Real-time data analysis is available through the communication ports, enabling monitoring of motor revolution, ampere-hour, and watt-hour counting.

7. Maintenance

Proper maintenance ensures the longevity and reliable performance of your FLIPSKY FSESC 75350.

• Cooling: The aluminum alloy case and water cooling enclosure are designed for efficient heat dissipation. Ensure the water cooling system is properly connected and free of obstructions, especially during high-current operation.
• Inspection: Regularly inspect all electrical connections for tightness and signs of wear or corrosion. Replace any damaged wires or connectors immediately.
• Cleaning: Keep the ESC clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Avoid using solvents or harsh chemicals.
• Storage: When not in use for extended periods, store the ESC in a dry, cool environment.

8. Troubleshooting

If you encounter issues with your FLIPSKY FSESC 75350, consider the following troubleshooting steps:

• No Power: Verify battery connections, battery voltage, and ensure the power switch (if any) is on. Check for blown fuses in the power circuit.
• Motor Not Spinning:
• Check motor phase wire connections.
• Ensure sensor wires (if used) are correctly connected.
• Connect to VESC_TOOL and perform motor detection.
• Review input source settings (PPM, ADC, etc.) and ensure your controller is sending a valid signal.
• ESC Damage After Firmware Update: As warned, new firmware versions can cause issues. If this occurs, attempt to re-flash the recommended factory firmware 5.2. If unsuccessful, the ESC may be permanently damaged.
• Overheating: Ensure the water cooling system is functioning correctly. Reduce load or improve airflow if operating in high ambient temperatures. Check for short circuits in motor windings.
• Unstable Operation: Check for loose connections. Re-run motor detection in VESC_TOOL. Verify that the phase filter is disabled if using firmware 5.3 or higher.

For persistent issues, utilize the real-time data logging features of VESC_TOOL to gather diagnostic information. Consult online VESC communities or FLIPSKY support for advanced troubleshooting.
