Setup and Wiring
Careful wiring is essential for the safe and correct operation of the FSESC 75200. Refer to the wiring diagram below for proper connections.

Connection Points:
- Battery Connection: Connect your battery pack (3-16S, 14-75V) to the main power cables (typically 10AWG). Ensure correct polarity.
- Motor Connection: Connect the three phase wires from your motor to the corresponding outputs on the ESC (typically 8AWG).
- UART 2 (1): For serial communication, e.g., Bluetooth module, screen display.
- PPM (2): For Pulse Position Modulation input, typically from a receiver for remote control.
- USB (3): For connecting to a computer for configuration via VESC_TOOL.
- SWD (4): For debugging and advanced firmware development.
- CAN (5): For CAN bus communication, allowing multiple VESC-based devices to communicate.
- SENSE (6): Sensor input for motor feedback (e.g., Hall sensors, ABI).
- COMM (7): General communication port.
- AUX (8): Auxiliary power or signal port.
Physical Dimensions:
The FSESC 75200 is available with different enclosures. Consider the dimensions for your installation space.


Operation and Configuration
The Flipsky FSESC 75200 is programmable via the VESC_TOOL software. This tool allows for detailed configuration of motor parameters, control modes, and protection settings.
Firmware and VESC_TOOL Usage:
- Current Firmware: The ESC ships with Firmware 5.02. Firmware upgrades are available.
- Critical Note for Firmware 5.03 and Newer: If upgrading to firmware version 5.03 or any newer version (e.g., using VESC_TOOL 3.01 or later), it is absolutely critical to turn off the phase filter function. In VESC_TOOL, set the phase filter option to "false". Failure to do so will result in ESC damage.
- Wizard Interface Caution: When using the VESC_TOOL wizard interface, do NOT restore the default parameters if you have upgraded to firmware 5.03 or newer and disabled the phase filter. Restoring defaults will re-enable the phase filter, potentially damaging the ESC.
- Configuration: Use VESC_TOOL to set up motor detection, input mapping (PPM, ADC, etc.), battery limits, and other operational parameters according to your specific application.
Maintenance
To ensure the longevity and reliable performance of your FSESC 75200, follow these general maintenance guidelines:
- Regular Inspection: Periodically inspect all connections for signs of wear, corrosion, or loose contacts. Ensure all wires are securely fastened.
- Cleanliness: Keep the ESC clean and free from dust, dirt, and moisture. If using the water-cooling enclosure, ensure the cooling lines are clear and free of blockages.
- Temperature Management: Monitor operating temperatures. While the ESC has built-in over-temperature protection, prolonged high temperatures can reduce lifespan. Ensure adequate airflow or proper water cooling if applicable.
- Storage: Store the ESC in a dry, cool environment when not in use.
Troubleshooting
If you encounter issues with your FSESC 75200, consider the following common problems and solutions:
- ESC Damage After Firmware Update (5.03+):
Symptom: ESC malfunctions or is damaged after updating firmware to version 5.03 or newer.
Solution: This is likely due to the phase filter being enabled. Ensure the phase filter function is turned OFF ("false") in VESC_TOOL when using firmware 5.03 or newer. Do not restore default parameters via the wizard after disabling the phase filter.
- No Power/Intermittent Power:
Symptom: The ESC does not power on, or power is intermittent.
Solution: Check all battery connections for secure contact and correct polarity. Verify battery voltage is within the 14-75V (3-16S) range. Inspect power cables for damage.
- Motor Not Spinning/Incorrectly Spinning:
Symptom: Motor does not spin, spins erratically, or in the wrong direction.
Solution: Perform motor detection in VESC_TOOL. Check motor phase wire connections. Verify sensor connections (if using sensored mode). Ensure input source (PPM, etc.) is correctly configured and calibrated.
- Overheating:
Symptom: ESC becomes excessively hot during operation.
Solution: Check for proper cooling (airflow or water cooling). Reduce load on the motor or adjust VESC_TOOL settings (e.g., current limits). Ensure motor and battery are appropriately matched to the ESC's capabilities.

User Tips
No specific user tips were available from customer reviews or Q&A for this product at this time. However, general best practices for ESCs include:
- Always perform a bench test before full deployment to verify all settings and connections.
- Keep firmware updated to benefit from improvements, but always review release notes for critical changes like the phase filter setting.
- Ensure your battery and motor are well-matched to the ESC's voltage and current ratings to prevent damage and ensure efficiency.
