Parameter Description
26-15 Term. X42/1 High Ref./Feedb. Value
Range: Function:

999999.999 ] that corresponds to the high voltage
value set in parameter 26-11 Terminal
X42/1 High Voltage.
26-16 Term. X42/1 Filter Time Constant
Range: Function:
0.001 s [0.001 - Enter the time constant. This is a first-
*
10 s] 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.
NOTICE
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.

26-20 Terminal X42/3 Low Voltage
Range: Function:
0.07 V [ 0 - par. Enter the low voltage value. This analog

the low reference/feedback value set in
parameter 26-24 Term. X42/3 Low Ref./Feedb.
Value.
26-21 Terminal X42/3 High Voltage
Range: Function:
10 V [ par. 6-30 Enter the high voltage value. This analog

high reference/feedback value set in
parameter 26-25 Term. X42/3 High Ref./Feedb.
