26-16 Term. X42/1 Filter Time Constant
Range: Function:
NOTICE
0.005 s [0.005 - 10
*
s]
This parameter cannot be adjusted
while the motor is running.
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.
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 the frequency converter control,
rather than being used as a decentral I/O system,
such as a building management system.
