CT1 control
• If the operating current reaches I1, the operating frequency of the compressor decrease.
• After decreasing the operating frequency by 1step, if operating current is below I1 for 60 seconds continuous-
ly, the operating frequency of compressor increase by 1step.
■
CT2 control
• If the operating current of the appliance reaches I2, the compressor stop instantly and 2 minutes later the
compressor restart again.
• If CT2 occurs 5 times within 1hour, the appliance turn off and blinks 7 times(ERROR CODE7).
❇
I1:Current of operating frequency down
I2: Current of compressor cut off
cf. I1 is set the lowest level between intial value and in case dectection of dc paeak current.

DC Peak Current Error by a fault signal of IPM
• If the operating current of IPM reaches 35A ±3A, the compressor stop instantly.
• If DC PEAK occurs 5 times within 1 hour, the appliance turns off and blinks 6 times(ERROR CODE6).
■
DC Peak Current Error by the compressor lock
• If the DC LINK voltage below DC 140V occurs 5 times within 1 hour while the compressor is operating, the
