3.7.3 6-2* Analog Input 54
Parameters for configuring the scaling and limits for
analog input 54 (terminal 54).
6-20 Terminal 54 Low Voltage
Range:
Function:
0.07 V
*
[0 -
10 V]
Enter the voltage (V) that corresponds to the
low reference value (set in
). The value must be set at >1
V to activate
6-01 Live Zero Timeout Function
.
6-21 Terminal 54 High Voltage
Range:
Function:
10 V
*
[0 - 10 V] Enter the voltage (V) that corresponds to the
high reference value (set in
).
6-22 Terminal 54 Low Current
Range:
Function:
4 mA
*
[0 -
20 mA]
Enter the low current value. This reference
signal should correspond to the low reference/
feedback value, set in
. The value must be set at >2 mA to
activate the Live Zero Timeout Function in
6-01 Live Zero Timeout Function
6-23 Terminal 54 High Current
Range:
Function:
20 mA
*
20.00 mA

Enter the high current value
corresponding to the high
reference/feedback value set in
6-25 Terminal 54 High Ref./Feedb.
Value
6-24 Terminal 54 Low Ref./Feedb. Value

Enter the reference or feedback value that
corresponds to the voltage or current set in
6-25 Terminal 54 High Ref./Feedb. Value

*
[-4999 -
4999 ]
Enter the reference or feedback value
that corresponds to the voltage or
current set in
.
6-26 Terminal 54 Filter Time Constant
Range:
Function:
0.01 s
*
[0.01 -
10 s]
Enter the time constant. This is a first-order
digital low pass filter time constant for
suppressing electrical noise in terminal 54. A
high time constant value improves dampening
but also increases the time delay through the
filter.

3.7.4 6-7* Analog/Digital Output 45
Parameters for configuring the scaling and limits for
analog/digital output Terminal 45. Analog outputs are
current outputs: 0/4-20 mA. Resolution on analog output is
12 bit. Analog output terminals can also be setup as digital
output.
