Function:
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:
Live Zero monitoring and can be used, for
example, if the analog outputs are used as part of
a decentral I/O system (e.g., when not part of any
adjustable frequency drive related control
functions, but feeding an external control system
with data).
Function:
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:
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).
