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%.)
