Function:
Enter the analog input scaling
value that corresponds to the
high voltage value set in
26-11 Terminal X42/1 High
Voltage.
Function:
Enter the time constant. This is a first-order
digital low pass filter time constant for
suppressing noise in terminal X42/1. A high
time constant value improves dampening
but also increases the time delay through
the filter. This parameter cannot be
adjusted while the motor is running.
Function:
This parameter makes it possible to enable the Live
Zero monitoring. E.g. where the analog input is a
part of the frequency converter control, rather than
being used as part of a decentral I/O system, such
as a Building Management System.
Function:
Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
26-24 Term. X42/3 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 26-25 Term. X42/3
High Ref./Feedb. Value.
Function:
Enter the analog input scaling
value that corresponds to the low
voltage value set in 26-20 Terminal
X42/3 Low Voltage.
