26-10 Terminal X42/1 Low Voltage
Range: Function:
0.07 V* [0.00 - par. 6-31 V] Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value set in par.26-14
Term. X42/1 Low Ref./Feedb. Value .
26-11 Terminal X42/1 High Voltage
Range: Function:
10.00 V* [par. 6-30 - 10.00 V] Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par.26-15
Term. X42/1 High Ref./Feedb. Value .
26-14 Term. X42/1 Low Ref./Feedb. Value
Range: Function:
0.000 N/A* [-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the low voltage value set in par.

26-15 Term. X42/1 High Ref./Feedb. Value
Range: Function:
100.000 N/
A*
[-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the high voltage value set in par.

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, for example where the analog
input is a part of the adjustable frequency drive control, rather than being used as part of a decentral
I/O system, such as a building management system.

26-20 Terminal X42/3 Low Voltage
Range: Function:
0.07 V* [0.00 - par. 6-31 V] 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* [par. 6-30 - 10.00 V] Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/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 N/A* [-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the low voltage value set in par.
