Function:
[ 0 - par. 6-31 Enter the low voltage value. This
analog input scaling value should
correspond to the low reference/
feedback value set in
parameter 26-24 Term. X42/3 Low
Ref./Feedb. Value.
Function:
[ par. 6-30 - Enter the high-voltage value. This
analog input scaling value should
correspond to the high reference/
feedback value set in
parameter 26-25 Term. X42/3 High
Ref./Feedb. Value.
Function:
[-999999.999 Enter the analog input scaling value
that corresponds to the low-voltage
value set in
parameter 26-20 Terminal X42/3 Low
Voltage.
Function:
[-999999.999 Enter the analog input scaling value
that corresponds to the high-
voltage value set in
parameter 26-21 Terminal X42/3 High

[0.005 - 10 s]
This parameter cannot be
adjusted while the motor is
running.
Enter the time constant. This is a
first-order digital low-pass filter
time constant for suppressing noise
in terminal X42/3. A high time
constant value improves
dampening, but also increases the
time delay through the filter.

3.24.4 26-3* Analog Input X42/5
Parameters for configuring the scaling and limits for analog
input, terminal X42/5.

Range:
0.07 V

26-35 Term. X42/5 High Ref./Feedb. Value
Range:
100
*
Function:
This parameter makes it possible to
enable the live zero monitoring, for
example, where the analog input is
the frequency converter control,
rather than being used as a
decentral I/O system, such as a
building management system.
