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.

H

•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.

Title	Function	Adjustment range	Default setting
		1: -10 to +10°C
	Annual average ambient temperature	2: 11 to 20°C
H		3: 21 to 30°C	3
	(For parts replacement alarms)	4: 31 to 40°C
		5: 41 to 50°C
		6: 51 to 60°C

+Display of part replacement alarm information

Part replacement alarm information (⇒ See page H-3) in the Status monitor mode allows you to check on the time of replacement.

An example of display: O___

+Output of part replacement alarm signal

Assign the part replacement alarm function (function No. 44 or 45. ⇒ See page K-18) to an output terminal.

An example of setting: To assign the function to the RY-RC terminal 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.
