Chapter 1：Introduction
This connection tester is a support tool for driving a 3-phase BLDC motor with
KE-KA44143A evaluation board.
Power of this connection tester is supplied from a PC via USB. The connection
between the KE-KA44143A evaluation board and the motor can be determined
by connecting the 3-phase terminal and the Hall signal terminal of the motor to
the tester and rotating the motor manually.
The test result can be confirmed by the LED on the tester. If the connection are
correct, the blue color PASS LED will light up. If the connection is incorrect, the
red color FAIL LED lights up. The yellow color Error LEDs indicate the details of
the connection error, so the incorrect connection can be corrected easily.
