26-35 Term. X42/5 High Ref./Feedb. Value
Range:
Function:
100
*
[-999999.999 -
999999.999 ]
Enter the analog input scaling
value that corresponds to the high
voltage value set in
.
26-36 Term. X42/5 Filter Time Constant
Range:
Function:
0.001 s
*
[0.001 - 10
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.
NOTE
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 of the frequency converter control, rather
than being used as of a decentral I/O system,
such as a Building Management System.

26-41 Terminal X42/7 Min. Scale
Range:
Function:
0 %
*
[0 -
200 %]
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
Range:
Function:
100
%
*
[0 -
200
%]
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 10 V at full
scale; or 10 V at an output below 100% of the
maximum signal value. If 10 V 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% = 10 V. If a voltage between 0
and 10 V 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 %
