26-15 Term. X42/1 High Ref./Feedb. Value
Range: Function:
100.000 * [-999999.999 -
999999.999 ]
Enter the analog input scaling
value that corresponds to the high
voltage value set in
par. 26-11 Terminal X42/1 High
Voltage.
26-16 Term. X42/1 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 X42/1. 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.
26-17 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
part of the frequency converter control, rather than
being used as part of a decentral I/O system, such
as a Building Management System.

3.24.3 26-2* Analog Input X42/3
Parameters for configuring the scaling and limits for analog
input, terminal X42/3.
26-20 Terminal X42/3 Low Voltage
Range: Function:
0.07 V * [Application
dependant]
Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
par. 26-24 Term. X42/3 Low Ref./Feedb.
Value.
26-21 Terminal X42/3 High Voltage
Range: Function:
10.00 V * [Application
dependant]
Enter the high voltage value. This
analog input scaling value should
correspond to the high reference/
feedback value set in par. 26-25 Term.
X42/3 High Ref./Feedb. Value.
26-24 Term. X42/3 Low Ref./Feedb. Value
Range: Function:
0.000 * [-999999.999 -
999999.999 ]
Enter the analog input scaling value
that corresponds to the low voltage
value set in par. 26-20 Terminal X42/3
Low Voltage.
26-25 Term. X42/3 High Ref./Feedb. Value
Range: Function:
100.000 * [-999999.999 -
999999.999 ]
Enter the analog input scaling
value that corresponds to the high
voltage value set in
par. 26-21 Terminal X42/3 High
Voltage.
26-26 Term. X42/3 Filter Time Constant
Range: Function:
0.001 s * [0.001 -
10.000 s]

digital low pass filter time constant for
suppressing noise in terminal X42/3. A high

3.24.4 26-3* Analog Input X42/5
Parameters for configuring the scaling and limits for analog
input, terminal X42/5.
26-30 Terminal X42/5 Low Voltage
Range: Function:
0.07 V * [Application

Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
par. 26-34 Term. X42/5 Low Ref./Feedb.
