Function:
Enter the analog input scaling value that corresponds to the high voltage/high current value set in
Terminal 54 High Voltage and par. 6-23 Terminal 54 High Current .
par. 6-21
Function:
Enter the time constant. This is a first-order 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.
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 con-
verter related control functions, but feeding a Building Management System with data).
Function:
Select the function of Terminal 42 as an analog current output. A motor current of 20 mA corre-
sponds to I .
