Functional Description 111
Communication information
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 over-
ride 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
characteristic.
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 sin-
gle 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 Auto-
set 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.
