10.3.2 Setting the Motor Direction and the Machine Movement
Direction
You must set the motor direction and the machine movement direction. To perform fully-closed
loop control, you must set both Pn000 = n.X (Direction Selection) and Pn002 = n.X
(External Encoder Usage).
Pn000
(2000 hex)
=n.X
(Direction
Selection)
• Phase B leads in the divided pulses for a forward reference regardless of the setting of Pn000
= n.X.
• Forward direction: The direction in which the pulses are counted up.
• Reverse direction: The direction in which the pulses are counted down.
Related Parameters
 Pn000 = n.
Refer to the following section for details.
5.4 Motor Direction Setting on page 5-14
 Pn002 = n.X
When you perform fully-closed loop control, set Pn002 to n.1 or n.3.

Determine the setting of Pn002 = n.X as described below.
• Set Pn000 to n.0 (Use the direction in which the linear encoder counts up as the for-
ward direction) and set Pn002 to n.1 (The external encoder moves in the forward
direction for CCW motor rotation).
• Manually rotate the motor shaft counterclockwise.
• If the fully-closed feedback pulse counter counts up, do not change the setting of Pn002
(Pn002 = n.1).
• If the fully-closed feedback pulse counter counts down, set Pn002 to n.3.

Meaning
Do not use an external encoder.
External encoder moves in forward
direction for CCW motor rotation.

tion for CCW motor rotation.
