6.14.9 Analog input disconnection detection

H

: Analog input disconnection detection

• Function

This parameter is used to detect a break in an analog signal to the VI/S3 terminal. If an analog signal is below the level set with H for 0.3 seconds (approx.), the inverter will assume the signal to be broken and it will trip and display the error message “G.” (The Analog input disconnection detection function is disabled if H is set to 0.0%.)

Title	Function	Adjustment range	Default setting
H	Analog input	0: Disabled	0
	disconnection detection	1~100%

settings

 : Permitted _____ EOQF and HOQF settings cannot be changed during operation. (Default)

 : Prohibited _____ All parameters are read/write-protected.

 : Permitted _____ EOQF and HOQF settings also can be changed during operation.

 : Prohibited _____ Frequency can be changed from the operation panel but all other

parameters are read/write-protected.

 : Permitted _____ The emergency stop function cannot be controlled from the operation panel

and EOQF and HOQF settings cannot be changed during operation.

 : Prohibited _____ The emergency stop function cannot be controlled from the operation panel

but all parameters are read/write-protected.

 : Permitted _____ The emergency stop function cannot be controlled from the operation panel

and EOQF and HOQF settings also can be changed during operation.  : Prohibited _____ The emergency stop function cannot be controlled from the operation panel,

frequency can be changed on the operation panel, but any other parameters are write/read-protected.

Note: Some parameters cannot be changed during operation, no matter how H is set. (See 4.1.4.)

■Canceling the setting

Only the setting of H can be changed anytime, no matter how it is set.
