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.

motor may not operate or it may run out of control. Always confirm these items before you oper-
ate the Servomotor.
