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:
[-999999.999 - Enter the analog input scaling
value that corresponds to the
high voltage/high current value
set in 6-21 Terminal 54 High
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. E.g. to be used if the
analog outputs are used as of a de-central I/O
system (e.g. when not as of any frequency
converter related control functions, but feeding a
Building Management System with data).
