Minimum Pre-Alarm Action [4131]
Setting of the alarm behaviour when a “Minimum Pre-
Alarm” has been detected.
Minimum Pre-Alarm Level [4132]
The value of the minimum pre-alarm level is given as a
percentage of the nominal motor power [223]. When the
actual shaft power (shown within brackets in the display) falls
to a value below this level, the “Minimum Pre-Alarm Delay”
timer, menu [4133], will start counting down. When the
delay time has elapsed, an alarm will be generated according
to the selected “Minimum Pre-Alarm Action” in menu
[4131].
This menu can be set manually to the required alarm level, or
it can be set indirectly, by performing an “Autoset”. See
further information in Fig. 40, page 57.

The “Min Pre-Alarm Level” is set to 40%. This means that
when the shaft power falls to a value below 40% of the
nominal motor power, the alarm delay timer starts counting
down.
