Wiring diagram
1) PT2+,PT- is the PT100 terminal of the motor, please short connect when not connected, otherwise it will report the motor overheating fault.
2）S3 is the PTC terminal of the motor. If it is not connected, please short-circuit it with COM or set P4.02 to 0, otherwise it will also report the motor overheating fault.
