Function:
Enter the low voltage value. This analog
input scaling value should correspond
to the low reference/feedback value, set
in 6-24 Terminal 54 Low Ref./Feedb. Value.
Function:
Enter the high voltage value. This
analog input scaling value should
correspond to the high reference/
feedback value set in 6-25 Terminal 54
High Ref./Feedb. Value.
Function:
0.00 - Enter the low current value. This reference
signal should correspond to the low
reference/feedback value, set in
6-24 Terminal 54 Low Ref./Feedb. Value. The
value must be set at >2 mA in order to
activate the Live Zero Timeout Function in
6-01 Live Zero Timeout Function.
Function:
par. 6-22 - Enter the high current value
corresponding to the high reference/
feedback value set in 6-25 Terminal
54 High Ref./Feedb. Value.
Function:
Enter the analog input scaling
value that corresponds to the low
voltage/low current value set in
6-20 Terminal 54 Low Voltage and
6-22 Terminal 54 Low Current.
Function:
Enter the analog input scaling
value that corresponds to the
high voltage/high current value
set in 6-21 Terminal 54 High

Function:
Voltage and 6-23 Terminal 54 High
Current.
Function:
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.
Function:
This parameter makes it possible to disable the
Live Zero monitoring. For example, this to be
used if the analog outputs are used as part of a
de-central I/O system (e.g., when used not as part
of any adjustable frequency drive related control
functions, but for feeding a building management
system with data).
Function:
0.00 - par. Sets the analog input scaling value to
correspond to the low reference/
feedback value (set in 6-34 Term.
X30/11 Low Ref./Feedb. Value).
Function:
par. 6-30 - Sets the analog input scaling value to
correspond to the high reference/
feedback value (set in 6-35 Term.
X30/11 High Ref./Feedb. Value).
