26-16 Terminal 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 Terminal 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.

26-20 Terminal X42/3 Low Voltage
Range:
Function:
0.07 V
*
[0.00 - par. 26-21]
Enter the low voltage value. This analog input scaling value should correspond to the low reference/feedback
value set in par 26-24.
26-21 Terminal X42/3 High Voltage
Range:
Function:
10.0 V
*
[Par. 26-20 - 10.0 V]
Enter the high voltage value. This analog input scaling value should correspond to the high reference/feedback
value set in par 26-25.
26-24 Terminal X42/3 Low Ref./feedb. Value
Range:
Function:
0.000 Unit
*
[-100000.000 - par.
26-25]
Enter the analog input scaling value that corresponds to the low voltage value set in par 26-20.
26-25 Terminal X42/3 High Ref./feedb. Value
Range:
Function:
100.000 Unit
*
[Par. 26-24 -
1000000.000]
Enter the analog input scaling value that corresponds to the high voltage value set in par 26-21.
26-26 Terminal X42/3 Filter Time Constant
Range:
