3.8 Parameters 6-** Analog In/Out
3.8.1 6-0* Analog I/O Mode
Parameter group for setting up the analog I/O congu-
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.
6-00 Live Zero Timeout Time
Range: Function:
10
s*
[1 -
99 s]
Enter the live zero timeout in s. Live zero timeout
time is active for analog inputs, that is 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
parameter 6-01 Live Zero Timeout Function is
activated if the input signal on terminal 53 or 54
is below 50% of the value 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.
The function can also be activated for a time
period dened in parameter 6-00 Live Zero
Timeout Time. If several timeouts occur simulta-
neously, the frequency converter prioritizes the
timeout functions as follows:
6-01 Live Zero Timeout Function
Option: Function:
1. Parameter 6-01 Live Zero Timeout
Function.
2. Parameter 8-04 Control Word Timeout
Function.

on analog inputs is lower than 50% of the
low value for a time period dened in
parameter 6-00 Live Zero Timeout Time.
