3.8 Main Menu - Analog In/Out - Group 6

3.8.1 6-0* Analog I/O Mode
3 3
Parameter group for setting up the analog I/O configu-
ration.
The Adjustable frequency drive is equipped with 2 analog
inputs: Terminal 53 and 54. The analog inputs can freely
be allocated to either voltage (0‒10V) or current input
(0/4‒20mA)
NOTE!
Thermistors may be connected to either an analog or a
digital input.

6-01 Live Zero Timeout Function
Option:
3-54
Function:
Enter the Live Zero Timeout time period. Live Zero
Timeout 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.
Function:
Select the timeout 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 timeouts
occur simultaneously, the Adjustable frequency
drive prioritizes the timeout functions as
follows:
1. 6-01 Live Zero Timeout Function
2. 8-04 Control Timeout Function
The output frequency of the adjustable
frequency drive can be:
•
[1] frozen at the present value
•
[2] overruled to stop
•
[3] overruled to jog speed
