Autoset Alarm [41A]
The Autoset Alarm function can measure the nominal load
that is used as reference for the alarm levels. If the selected
“Load Type [415]” is Basic it copies the load the motor is
running with to the menu “Normal Load [41B]”. The
motor must run on the speed that generates the load that
needs to be recorded. If the selected “Load Type [415]” is
Load Curve it
performs a test-run and populates the “Load
Curve [41C]” with the found load values.
The default set levels for the (pre)alarms are:
These default set levels can be manually changed in menus
[416] to [419]. After execution the message “Autoset OK!” is
displayed for 1s and the selection reverts to “No”.
