In/Out
3.8.1 6-0* Analog I/O Mode
3 3
Parameter group for setting up the analog I/O configu-
ration.
The frequency converter is equipped with 2 analog inputs:
•
Terminals 53
•
Terminals 54
The analog inputs can be allocated freely to either voltage
(0–10 V) or current input (0/4–20 mA).
NOTICE
Thermistors may be connected to either an analog or a
digital input.

associated with the selected current input drops
below 50% of the value set in
For a time period longer than the time set in
parameter 6-00 Live Zero Timeout Time, the function
selected in parameter 6-01 Live Zero Timeout
Function is activated.

or for a time period defined in
parameter 6-00 Live Zero Timeout Time. If several
time-outs occur simultaneously, the frequency
converter prioritises the time-out functions as
