CG Drives & Automation,01-5326-01r5 163
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”.
Normal Load [41B]
Set the level of the normal load. The alarm or pre alarm will
be activated when the load is above/under normal load ±
margin.
Communication information
Load Curve [41C]
The load curve function can be used with any smooth load
curve. The curve can be populated with a test-run or the
values can be entered or changed manually.
Load Curve 1-9 [41C1]-[41C9]
The measured load curve is based on 9 stored samples. The
curve starts at minimum speed and ends at maximum speed,
the range in between is divided into 8 equal steps. The
measured values of each sample are displayed in [41C1] to
[41C9] and can be adapted manually. The value of the 1st
sampled value on the load curve is displayed.
