12-6
▶ Function
- Inverter control of DD motor
- Detect motor rpm using Hall_IC in the DD_MOTOR
- Detect DC_LINK voltage
- Detect condition (such as excess current) of motor control part
▶ Description
- PWM output will be available at PIN no. 10~15 with reference to active high when using INVERTER control of
DD_MOTOR
- IPM will give Lo signal to 16 PIN on the MICOM through F0 for abnormal cases such as over 16A is generated in the
IPM or upper phase current is controlled less than 10.5V.
- Depending on the ON/OFF condition of HALAL_IC inside the DD_MOTOR, High/Low signal will be put through PIN 19
and 20 on the MICOM, and ROTOR position of DD_MOTOR and rpm will be detected
- 10% of DC_LINK voltage will be put into PIN 28, and will detect A/D function DC_LINK voltage inside the MICOM
