5.8 Selecting the Phase Sequence for a Linear Servomotor
You must select the phase sequence of the Linear Servomotor so that the forward direction of
the Linear Servomotor is the same as the encoder’s count-up direction.
Before you set the Linear Servomotor phase sequence (Pn080 = n.X), check the follow-
ing items.
• Confirm that the signal from the linear encoder is being received normally.
• Make sure that the forward direction of the Linear Servomotor and the count-up direction of
the linear encoder are in the same direction.

If you do not confirm the above items before you attempt to operate the Servomotor, the Servo-
motor may not operate or it may run out of control. Always confirm these items before you oper-
ate the Servomotor.
