Autoset function with alarm margins
See Fig. 41. The quickest way to adapt the monitor to
different load situations is to use the “Autoset” function,
which automatically applies four “Alarm Margins” to a
registered “Normal Load” level whilst the motor is running.
The “Alarm Margins” are set as a percentage added to or
subtracted from the “Normal Load”, which is the shaft
power during normal operation conditions. See calculations
in Table 28, page 101. The “Normal Load” is expressed as a
percentage of the nominal motor power (i.e. 100% normal
load equals the motor power set in menu [223]).
The “Alarm Margins” are set under menu [417], and
“Normal Load” is automatically registered when activating
the autoset function in menu [4175] AutoSet Alarm. The
actual “Normal Load” value can then be viewed in menu
[4176].
Every time a new “Autoset Alarm” command is executed, the
actual shaft power value will be updated as the “Normal
Load” value, with the alarm levels following this.
Autoset can also be activated using a remote signal (edge-
triggered) by setting the function of any digital input to
“Autoset”.

NOTE: A manual change of any of the “Alarm Levels” in
[411] - [414] will override the “Autoset” monitor
settings, and the “Normal Load” will be reset to “Off”.
NOTE: When “Autoset” is used, set Alarm Levels will be
overwritten in the menus [4112], [4122], [4132] and
[4142].
