Attention Points when you receive the controller Please:
- When you receive the controller, please test without load and do not connect motor, first check if the controller can successfully connect to your computer, if ok, then connect to motor and you can start to adjust parameters.
- Do not use switching power supply, the instant voltage when switching power supply connect to controlleris very high, which would easy damage the controller.
- Do not push the throttle too hard when test without load, gently and slowly speed up.
- Be cautious when adjust parameters, if parameters set mistake, would also easy damage the controller.
- Do not recommend to work with BLDC mode, please use FOC mode.
- If you use UART port, the wire better do not over 0.5m or even shorter, and better use Stranded wire.
Above notices are only suggestions based on the experience of our engineers. how to actually operate is up to you. Parameters for different setup is also different, please noted.
