Chapter 6 Troubleshooting - 79 -
Figure 41 illustrates the alignment of phases U, V, and W with Halls 1, 2, and
3 as viewed from the front of the shaft. The illustration assumes the following:
• Hall signals that are High equal
TRUE signals.
• Hall 1 is the least significant bit (LSB).
• Hall 3 is the most significant bit (MSB).
• There is one hall cycle and one electrical cycle per pole pair on the
motor.
