3.8 AN-## Analog In/Out
Parameter group related to the Analog Inputs and
Outputs.
3.8.1 AN-0# Analog I/O Mode
Parameters to configure the Analog Inputs and Output
time out period for lost signals.
AN-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 AN-10 Terminal 53
Low Voltage , AN-12 Terminal 53 Low Current ,
AN-20 Terminal 54 Low Voltage or AN-22 Terminal
54 Low Current for a time period longer than the
time set in AN-00 Live Zero Timeout Time , the
function selected in AN-01 Live Zero Timeout
Function will be activated.
AN-01 Live Zero Timeout Function
Option: Function:
Select the time-out function. The function set
in AN-01 Live Zero Timeout Function will be
activated if the input signal on terminal 53 or
54 is below 50% of the value in
AN-10 Terminal 53 Low Voltage , AN-12 Terminal
53 Low Current , AN-20 Terminal 54 Low Voltage
or AN-22 Terminal 54 Low Current for a time
period defined in AN-00 Live Zero Timeout
Time . If several time-outs occur simultaneously,
the frequency converter prioritises the time-
out functions as follows:
1. AN-01 Live Zero Timeout Function
2. O-04 Control Word Timeout Function

[20] Coast Coast: Overruled to Coast
[21] Coast and

Coast and trip: Overruled to Coast with
subsequent trip.
3.8.2 AN-1# Analog Input 53
Parameters to configure the scaling and limits for Analog
Input 1 (terminal 53)
AN-10 Terminal 53 Low Voltage
Range: Function:
0.07 V
*
[-10.00 - par.
AN-11 V]
Enter the low voltage value. This analog
input scaling value should correspond to
the minimum reference value, set in
AN-14 Terminal 53 Low Ref./Feedb. Value .
See also the section Reference Handling .
AN-11 Terminal 53 High Voltage
Range: Function:
10 V
*
[par. AN-10 -
10 V]
Enter the high voltage value. This analog
input scaling value should correspond to
the high reference/feedback value set in
AN-15 Terminal 53 High Ref./Feedb. Value .
AN-12 Terminal 53 Low Current
Range: Function:
0.14
mA
*
[0 - par.
AN-13 mA]
Enter the low current value. This
reference signal should correspond to the
minimum reference value, set in
F-52 Minimum Reference . The value must
be set at >2 mA in order to activate the
Live Zero Time-out Function in AN-01 Live
Zero Timeout Function .
AN-13 Terminal 53 High Current
Range: Function:
20 mA
*
[par. AN-12 -
20 mA]
Enter the high current value
corresponding to the high reference/
feedback set in AN-15 Terminal 53
High Ref./Feedb. Value .
AN-14 Terminal 53 Low Ref./Feedb. Value
Range: Function:
0
*
[-999999.999 -
999999.999]
Enter the analog input scaling value
that corresponds to the low
voltage/low current set in
AN-10 Terminal 53 Low Voltage and
AN-12 Terminal 53 Low Current .
AN-15 Terminal 53 High Ref./Feedb. Value
