2. FUNCTION EXPLANATION
FANUC AC SPINDLE MOTOR a series

DIRCT2-DIRCT1:
Setting of rotation direction at spindle orientation
DIRCT2 DIRCT1 Rotation direction at spindle orientation
0 0 By rotation direction immediately before
(It is CCW at the power on.)
0 1 By rotation direction immediately before
(It is CW at the power on.)
1 0 CCW (counterclockwise) direction looking from
shaft of motor
1 1 CW (clockwise) direction looking from shaft of motor
When ”By rotation direction immediately before” is set, ”rotation
direction immediately before” is determined to be the direction of rotation
performed at a level higher than the zero speed detection level (Output
signal SST = 0).
PCMGSL:
Selects the type of orientation.
Set this bit to 0 (orientation by a position coder).
PCPL2, PCPL1, PCPL0, PCTYPE:
Set a position coder signal.
Set these bits according to the type of detector being used. Set these bits
to ”0,0,0,0” when using a position coder.

EXTRF: Specifies whether an external one–rotation signal is used.
0: Not used.
1: Used.
RFTYPE: Specifies whether to invert the external one–turn signal.
0: The final signal is to be inverted.
1: The final signal is not to be inverted.
