*If
the voltage boost value
is
set too high, the motor will be overexcited, and
an
OL or OC trip may occur.
In
some cases, this may also shorten the life of the inverter.
* The
voltage boost value is automatically initially set for the max. applicable motor according to the
inverter capacity.
If a standard motor matching the inverter capacity is used, the value does not
necessarily need to be adjusted. Even when readjusting, setting to within
+2%
of the initial setting
value
is
recommended.
