6-3 Block-B parameters
The Block-B parameters are divided into the basic functions, extended functions and software option
functions.

7. 1. 7. Select the rated input voltage from the
following table.
When this data is changed, the
output voltage data will be changed
to the same value.
1 Max./base frequency

1. 0 9 Select the output frequency rating
from the combination below.
2 Motor rated output kW Inverter

0.10 500.00 Motor rated power at the base speed.
3 Rated output voltage V 200
/400.
39. 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.)
4 Max. frequency Hz 50.0 3.0 440.0
5 Base frequency Hz 50.0 1.0 440.0
When "B00-1" is a value other than 0,
these values will be rewritten with the
data set in B00-1

7 Carrier frequency 17.0 1.0 21.0 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.
