6-36 Term. X30/11 Filter Time Constant
Range: Function:
0.001 s* [0.001 - 10.000 s]
A 1
st
order digital low pass filter time constant for suppressing electrical noise on terminal X30/11.
Par. 6-36
Term. X30/11 Filter Time Constant cannot be changed while the motor is running.
6-37 Term. X30/11 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 decentral I/O system (e.g. when not part of any frequency converter
related control functions, but feeding a Building Management System with data).
