How to Programme the Frequ...
6-26 Terminal 54 Filter Time Constant
Range: Function:
0.001 s [0.001 - Enter the time constant. This is a first-order
*
10.000 s] digital low pass filter time constant for
suppressing electrical noise in terminal 54.
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.
6-27 Terminal 54 Live Zero
Option: Function:
This parameter makes it possible to disable the Live
Zero monitoring. E.g. to be used if the analog
outputs are used as part of a de-central I/O system
(e.g. when not as part of any frequency converter
related control functions, but feeding a Building
Management System with data).
