26-15 Term. X42/1 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
26-11 Terminal
X42/1 High Voltage .
26-16 Term. X42/1 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 X42/1. 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.
26-17 Term. X42/1 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.

3.20.3 26-2* Analog Input X42/3
26-20 Terminal X42/3 Low Voltage
Range: Function:
0.07 V
*
[ 0 - par.
6-31 V] Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
26-24 Term. X42/3 Low Ref./Feedb. Value .
26-21 Terminal X42/3 High Voltage
Range: Function:
10 V
*
[ par. 6-30 -
10 V] Enter the high voltage value. This analog
input scaling value should correspond to
the high reference/feedback value set in
26-25 Term. X42/3 High Ref./Feedb. Value .
26-24 Term. X42/3 Low Ref./Feedb. Value
Range: Function:
0

[ 0 - par.
6-31 V] Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
