Load Monitor and Process Protection [400]
Section 11-4
Ramp Alarm [413]
This function inhibits the (pre) alarm signals during acceleration/deceleration
of the motor to avoid
false alarms.
Communication information
Alarm Start Delay [414]
This parameter is used if, for example, you want to override an alarm during
the start-up procedure.
Sets the delay time after a run command, after which the alarm may be given.
•
If Ramp Alarm=On. The start delay begins after a RUN command.
•
If Ramp Alarm=Off. The start delay begins after the acceleration ramp.
Communication information
Load Type [415]
In this menu you select monitor type according to the load characteristic of
your application. By selecting the required monitor type, the overload and
underload alarm function can be optimized according to the load characteris-
tic.
When the application has a constant load over the whole speed range, i.e.
extruder or screw compressor, the load type can be set to basic. This type
uses a single value as a reference for the nominal load. This value is used for
the complete speed range of the VSD. The value can be set or automatically
measured. See Autoset Alarm [41A] and Normal Load [41B] about setting the
nominal load reference.
The load curve mode uses an interpolated curve with 9 load values at 8 equal
speed intervals. This curve is populated by a test run with a real load. This
can be used with any smooth load curve including constant load.
