3.7 AN-## Analog In/Out
3.7.1 AN-## Analog In/Out
Parameter group for configuration of the analog input and
output.
3.7.2 AN-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.
AN-00 Live Zero Timeout Time
Range:
Function:
10
s
*
[1 -
99 s]
Enter the live zero timeout in s. Live zero timeout
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 AN-10 Terminal 53 Low Voltage
•
Parameter AN-12 Terminal 53 Low Current
•
Parameter AN-20 Terminal 54 Low Voltage
•
Parameter AN-22 Terminal 54 Low Current
For a time period longer than the time set in
parameter AN-00 Live Zero Timeout Time
, the function
parameter AN-01 Live Zero Timeout
is activated.
AN-01 Live Zero Timeout Function
Option:
Function:
Select the timeout function. The function set in
parameter AN-01 Live Zero Timeout Function
is
activated if the input signal on terminal 53 or 54
is below 50% of the value in:
•
Parameter AN-10 Terminal 53 Low
Voltage
.
•
Parameter AN-12 Terminal 53 Low
Current
.
•
Parameter AN-20 Terminal 54 Low
Voltage
.
AN-01 Live Zero Timeout Function
Option:
Function:
•
Parameter AN-22 Terminal 54 Low
Current
.
The function can also be activated for a time
period defined in
. If several timeouts occur simulta-
neously, the frequency converter prioritizes the
timeout functions as follows:
1.
Parameter AN-01 Live Zero Timeout
Function
.
2.
Parameter O-04 Control Word Timeout
Function
.

speed
Overruled to maximum speed.
[5]
Stop and
trip
Overruled to stop with subsequent trip.
AN-02 Fire Mode Live Zero Timeout Function
Option:
Function:
Select the time-out function when Fire mode
is active. The function set in this parameter is
activated if the input signal on analog inputs
is lower than 50% of the low value for a time
period defined in
[0]
*
Off
[1]
Freeze
output
Frozen at the present value.
[2]
Stop
Overruled to stop.
[3]
Jogging
Overruled to jog speed.
[4]
Max. speed
Overruled to max. speed.
