NOTE :
When the data does not match
that of the mootor, satisfactory
characteristics may not be
obtained during the sensorless
vector running.
The full performances may
not be demonstrated if the
rating of a motor used is tow or
less than the maximum
applicable rating when
the sensor-less vector function
is used.
The sensor-less vector opera-
tion is disabled when two or
more motors are running.
Set this data properly according
to the motor used if its rating is
not the same as the maximum
applicable rating in V/f
operation.
