ROTA1: Indicates the relationship between the rotation directions of spindle and
spindle motor.
0: Rotates the spindle and spindle motor in the same direction.
1: Rotates the spindle and spindle motor in the reverse direction.
Judge the spindle rotation direction in the same state as that when the
motor rotation direction was judged from the motor shaft direction.
POSC1: Indicates the mounting direction of position coder.
0: Rotates the spindle and position coder in the same direction.
1: Rotates the spindle and position coder in the reverse direction.
Judge by position coder rotation direction when position coder rotation
direction is viewed from position coder shaft. Judge by spindle
rotation direction in the same state as that when the motor rotation
direction was judged from the motor shaft direction.
