Selecting The Phase Sequence For A Linear Servomotor - YASKAWA SGD7S Product Manual

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 motor, the motor may
not operate or it may run out of control. Always confirm these items before you operate the
motor.
