6.18.13 VI analog input break detection
: VI analog input break detection level
Function
The inverter will trip if the VI value remains below the specified value for about 0.3 seconds. In such a
case, "" is displayed.
=0: Disabled....Not detected.

6.18.14 Parts replacement alarms
: Annual average ambient temperature (Parts replacement alarms)
Function
You can set the inverter so that it will calculate the remaining useful lives of the cooling fan, main
circuit capacitor and on-board capacitor from the ON time of the inverter, the operating time of the
motor, the output current (load factor) and the setting of , and that it will display and send out
an alarm through output terminals when each component is approaching the time of replacement.

Note 1: Using enter the annual average temperature around the inverter. Be careful not to enter the
annual highest temperature
Note 2: Set at the time of installation of the inverter, and do not change its setting after the start of
use. Changing the setting may cause parts replacement alarm calculation error.
