DEFRTO:
Indicates the number of position coder signal pulses of the other
spindle (spindle 1) in differential mode.
0: 1024 p/rev 4 (4096 p/rev)
1: 512 p/rev 4 (2048 p/rev)

Standard setting: 0 0 0 0 0 0 0 1
MRDY1:Determines whether the MRDYA signal (machine ready signal) is used
or not.
0: Not used. (The MRDYA signal should be always set to 1.)
1: Used.
POSC2: Determines whether the position coder signal is used or not.
0: Not used.
1: Used.
Set this bit to ”1” when using the following functions: servo mode
(rigid tap/spindle positioning etc.), spindle synchronization control and
position coder method spindle orientation.
Beware that if this bit is set to ”1” with no position coder signal input,
then the position coder disconnection alarm (AL-27) will occur.
MGSEN:Indicates the mounting direction of magnetic sensor.
0: Rotates the motor and magnetic sensor in the same direction.
1: Rotates the motor and magnetic sensor in the reverse direction.
CAXIS1:Determines whether the high-resolution magnetic pulse coder is used
or not.
The Power Mate does not have this function.
0: Not used.
1: Used.
CAXIS2:Also used in speed detection of the Cs contour control position
detection signal.The Power Mate does not have this function.
0: Not used. (when spindle and spindle motor are separated)
1: Used. (in case of built-in spindle motor)
CAXIS3:Indicates the mounting direction for the Cs contour control.
The Power Mate does not have this function.
0: Rotates the spindle and position detection in the same direction.
1: Rotates the spindle and position detection in the reverse direction.
