6.17.13 Trip at VIA low level input mode
H : Trip at VIA 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.
6.17.14 Parts replacement alarms
H : Annual average ambient temperature (For 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 H, and that it will display and send out
an alarm through output terminals when each component is approaching the time of replacement.

H =
Note 1: Using H 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 parts replacement alarm calculation error.
