TROUBLESHOOTING
INVERTER CONTROLLER BOARD Connector Location
1. Inrush Current protecting area : It prevents an instant inrush of current generated in condenser when plug in.
2. PCB Power Source : Power source (HYBRID IC). It supplied DC15V and 5V to MICOM.
3. Location sensing resistance area : It senses motor location through the current detected.
4. Current sensing area : It senses the current from the SHUNT resistance and controls PWM DUTY.
5. COMP operating SIGNAL area : It receives COMP operating signal from MAIN PCB and conduct it.
6. BOOTSTRAP live part : Charging circuit that 1GBT of SPM can On/Off securely.
