Function:
Enter the analog input scaling value
that corresponds to the high voltage
value set in parameter 26-21 Terminal
X42/3 High Voltage.
Function:
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.
NOTICE
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
of the frequency converter control, rather than
being used as of a decentral I/O system, such as a
Building Management System.
Function:
Set the function of terminal X42/7 as an
analog voltage output.

Function:
[0 - 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 parameter 26-42 Terminal X42/7 Max.

Output Min Scale.
Function:
[0 - 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:
