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%.)
