999999.999 ] value that corresponds to the high
voltage value set in 26-21 Terminal
X42/3 High Voltage.
26-36 Term. X42/5 Filter Time Constant
Range: Function:
0.001 s [0.001 - 10 Enter the time constant. This is a first-
*
s] 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.

Function:
[0 - Scale the minimum output of the selected

200 %] 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.

Function:
[0 - Scale the maximum output of the selected analog
200 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:
