6.19.13 Trip at VI/II low level input mode
H : Trip at VI/II low level input mode
• Function
The inverter will trip if the VIA value remains below the specified value for about 0.3 seconds. In such
a case, "G" is displayed.
H=0: Disabled ........ The detection function is disabled.
H=1-100 ................ The inverter will trip if the VIA value remains below the specified value for about
0.3 seconds.

Note : The VIA input value may be judged earlier to be abnormal, depending on the degree of deviation of
the analog data detected.
6.19.14 Calculation for life alarms
H : Annual average ambient temperature (calculation for life 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 H, and that it will display and send out
an alarm through output terminals when each component is approaching the end of its useful life.

Note 1: Using Hѽ enter the annual average temperature around the inverter. Be careful not to enter the
annual highest temperature
Note 2: Set H at the time of installation of the inverter, and do not change its setting after the start of
use. Changing the setting may cause a life alarm calculation error.
