The full performances may
not be demonstrated if the
rating of a motor used is tow or
less than the maximum
applicable rating when
1 the sensor-less vector function
is used.
Initial
The sensor-less vector opera-
tion is disabled when two or
value
more motors are running.
Set this data properly according
