2-4. How to Control Voltage (During abnormal operation)

1) Voltage Control

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.

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

Abnormal if DC current flowing through IPM measured during high-speed motor rotation is

10A~12A or higher

Detection of abnormal current to be carried out by saving higher value among instant current values

and updating the data
