0: Spindl and motor are the same direction
1: Spindl and motor are the reverse direction
The rotation direction is judged from the same direction facing to the
motor Normally to the shaft of motor and the spindle.

0: The spindle and the position coder is the same direction
1: The spindle and the position coder is the reverse direction
The rotation direction of the position coder is judged facing to the
position coder shaft.
The rotation direction of the spindle is judged from the same direction
facing to the motor (Normally to the shaft).
(4) Set the parameter “Number of pulse of the position coder”

(5) Parameter setting relating to the system in which the position
coderis used.
When the gear ratio between the spindle and the position coder is 1:
2, 1: 4, and 1: 8.
Refer to each CNC operation manual about the relation between the
gear ratio and the parameter setting data.
