3.8 Parameters: 6-** Main Menu - Analog
In/Out
3.8.1 6-0* Analog I/O Mode
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.

[1 -
99 s] Enter the live zero time-out time period. Live zero
time-out time is active for analog inputs, i.e.
terminal 53 or terminal 54, used as reference or
feedback sources. If the reference signal value
associated with the selected current input drops
below 50% of the value set in
•
Parameter 6-10 Terminal 53 Low Voltage .
•
Parameter 6-12 Terminal 53 Low Current .
•
Parameter 6-20 Terminal 54 Low Voltage .
•
Parameter 6-22 Terminal 54 Low Current .
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.
6-01 Live Zero Timeout Function
Option: Function:
Select the timeout function. The function set in
6-01 Live Zero Timeout Function is activated, if
the input signal on terminal 53 or 54 is below
50% of the value in
•
6-10 Terminal 53 Low Voltage .
•
6-12 Terminal 53 Low Current .
•
6-20 Terminal 54 Low Voltage .
•

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
follows:
