Connection Guide
The ESC features multiple connection options, including PWM throttle, CAN communication, and fault signal outputs. The black wire serves as the ground, while the white, yellow, and blue wires are for throttle signal, fault signal, and RPM signal, respectively.
RPM Conversion Formula:
- M (Motor Speed) = E (Motor Electrical Frequency) × 60 / P (Number of Magnets on Motor)
Troubleshooting Guide
| Issue | Alarm | Cause | Solution |
|---|---|---|---|
| Motor won’t start | Quick beep | Throttle not at zero | Set throttle stroke to minimum |
| Motor won’t start | Beep every second | No throttle output from receiver | Check sender & receiver conditions |
| Voltage too low | Beep every second | Battery voltage below 16V | Use a fully charged battery |
| Voltage too high | Beep every second | Battery voltage above 80V | Use an appropriate battery |
| High Temperature | Beep every second | ESC overheating (>125°C) | Allow ESC to cool in a ventilated area |
