constant for suppressing electrical noise
on terminal X30/12.
NOTE
This parameter cannot be changed while the motor is
running.
6-47 Term. X30/12 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 of a decentral I/O
system (e.g. when not of any frequency converter
related control functions, but feeding a Building
Management System with data)
