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%.)
