Protection Function
Excessive High or Low Voltage
for Inverter Excessive Low Voltage at a Voltage is lower than 350V
Excessive High Voltage at a Voltage is higher than 750V
Abnormality of Current Sensor Stoppage at a current of compressor smaller than 0.5A
When the frequency is 15~18Hz after starting.
Cause of Abnormality: Failure of current Sensor
Failure of transistor module
Failure of compressor
Disconnected wiring
NOTE:
Characteristics are fluctuated by the current minimize control.
