The TRT is avialable in two congfigurations, Brush and Brushless motors. The Servo Controller and the Soft-
ware is different between the two. The following steps are for TRTs with Brushless motors. If you have the
Brush version go to section 3.

YSTEM
The layout of the A and B axes on the HAAS five-axis control are depicted below. The A axis is rotary motion
about the X axis, while the B axis determines rotary motion about the Y axis. The right hand rule can be used
to determine axis rotation for the A and B axes. When placing the thumb of the right hand along the positive X
axis, the fingers of the right hand will point in the direction of tool movement for a positive A axis command.
Likewise, when placing the thumb of the right hand along the positive Y axis, the fingers of the right hand will
point in the direction of tool movement for a positive B axis command. It is important to remember that the right
hand rule determines direction of tool movement and not the table movement direction. For the right hand rule,
the fingers will point opposite of the positive rotary table movement. Refer to the following figures.

NOTE: The previous figures represent one of many possible machine tool and table
configurations. You may have different table movements for positive direc-
tions, depending on the equipment, parameter settings, or five-axis software
being used.
