26-36 Term. X42/5 Filter Time Constant
Range:
Function:
0.001 s
*
[0.001 -
10.000 s]
Enter the time constant. This is a first-order
digital low pass filter time constant for
suppressing noise in terminal X42/5. 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.
26-37 Term. X42/5 Live Zero
Option:
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.

%
*
[0.00 -
200.00 %]
Scale the minimum output of the selected
analog signal at terminal X42/7, as a
percentage of the maximum signal level. E.g.
if a 0 V (or 0 Hz) is desired at 25% of the
maximum output value. Then programme
25%. Scaling values up to 100% can never be
higher than the corresponding setting in
26-42 Terminal X42/7 Max. Scale

26-42 Terminal X42/7 Max. Scale
Range:
Function:
100.00
%
*
[0.00 -
200.00
%]
Scale the maximum output of the selected analog
signal at terminal X42/7. Set the value to the
maximum value of the voltage signal output.
Scale the output to give a voltage lower than 10V
at full scale; or 10V at an output below 100% of
the maximum signal value. If 10V is the desired
output current at a value between 0-100% of the
full-scale output, programme the percentage
value in the parameter, i.e. 50% = 10V. If a voltage
between 0 and 10V is desired at maximum
output, calculate the percentage as follows:
(
10
V
desired maximum voltage
)
x 100 %
i.e.
5
V : 10V
5
V × 100 % = 200 %
