4-3-4. Sensing Current Area

1) It is the circuit which senses the current from the SHUNT resistance and controls PWM DUTY and the

converted value as voltage (about 0.5V) is applied to the MICOM PIN #18.

TROUBLESHOOTING

4-3-3. Location Sensing Resistance Area

1) The circuit makes an AD conversion from MICOM for about 3.3V that divides the Motor Back EMF voltage

(DC300V) by 3 of 300K resistance and 10K resistance.
