Parameter Description

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 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.
6-00 Live Zero Timeout Time
Range: Function:
10 [1 - Enter the live zero timeout in s. Live zero timeout
s 99 s] 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 defined in parameter 6-00 Live Zero
Timeout Time. If several timeouts occur simulta-
neously, the frequency converter prioritizes the
timeout functions as follows:
