3.8 Main Menu - Analog In/Out - Group 6
3.8.1 6-** Analog In/Out
Parameter group for configuration of the analog input and
output.
3.8.2 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:
Terminal 53 and 54. The analog inputs can freely be
allocated to either voltage (0-10 V) or current input (0/4-20
mA)
NOTE
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 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 falls
below 50% of the value set in 6-10 Terminal 53
Low Voltage, 6-12 Terminal 53 Low Current,
6-20 Terminal 54 Low Voltage or 6-22 Terminal 54
Low Current for a time period longer than the time
set in 6-00 Live Zero Timeout Time, the function
selected in 6-01 Live Zero Timeout Function will be
activated.
6-01 Live Zero Timeout Function
Option: Function:
Select the time-out function. The function
set
in 6-01 Live Zero Timeout Function will be
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 6-22 Terminal 54 Low Current for a time
period defined in 6-00 Live Zero Timeout
Time. If several time-outs occur simulta-
neously, the frequency converter prioritises
the time-out functions as follows
1.

Option: Function:
The function set in 6-01
Live Zero Timeout
Function will be activated if the input signal
on analogue inputs is below 50% of the
value defined in parameter groups 6-1* to
6-6* "Terminal xx Low Current” or “Terminal
xx Low Voltage" for a time period defined in
6-00 Live Zero Timeout Time.
