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

999999.999 ]
26-16 Term. X42/1 Filter Time Constant
Range: Function:
0.001 s [0.001 - Enter the time constant. This is a first-
*
10.000 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. 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.
