2-4. How to Control Voltage (during abnormal operation)
1) Voltage Control
①
Normal Voltage
DC-link voltage after wave rectification is directly impressed to IPM as 310 ~ 330V.
When motor starts operation, DC voltage changes with energy consumed by motor and/
or counter electromotive force of motor.
②
Identifying Abnormal Voltage
A. Occurrence of counter electromotive force
☞
In case of 450V or higher
B. Instant power failure and excessive energy consumption
☞
In case of 185V or lower
2-5. How to Control Current (during abnormal operation)
1) Current Abnormality Detection
①
Abnormal if DC current flowing through IPM measured during high-speed motor rotation is
10A~12A or higher
②
Detection of abnormal current to be carried out by saving higher value among instant current values
and updating the data
