Motor rated power at the base speed.
480.
This is the rated motor voltage, which
can not be set to a larger value than the
input voltage set in B00-0.
The Automatic Voltage regulator DC-
AVR does not operate when is set to 39.
(then the output voltage equals the input
voltage at the base frequency.)
When "B00-1" is a value other than 0,
440.0
these values will be rewritten with the
440.0
data set in B00-1

The noise can be lowered by
changing the PWM carrier frequency
and control method, which affects to
the sound generated from the motor.
This can be changed while running.
1.0 to 15.0: Monotone sound
method (Carrier frequency: 1.0 to
15.0kHz)
15.1 to 18.0: Soft sound method 1
