3.8 Parameters: 6-** Analog In/Out

3.8.1 6-0* Analog I/O Mode

The analog inputs can freely be allocated to be either
voltage (FC 301: 0..10V, FC 302: 0..+/- 10V) or current (FC
301/FC 302: 0/4..20mA) input.
NOTE!
Thermistors may be connected to either an analog or a
digital input.
6-00 Live Zero Timeout Time
Range: Function:
10 s [1 - Enter the Live Zero Timeout time period. Live Zero
*
99 s] 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.

6-01 Live Zero Timeout Function

Option: 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.
