This concludes the procedure to write the motor parameters.
After you write the motor parameters, you can use a monitor function to confirm that the
motor parameters are in the encoder.
If the motor parameters have not been written, no information on the Servomotor will be
displayed.

6.8 Selecting the Phase Sequence for a Linear Servomotor
You must select the phase sequence of the Linear Servomotor so that the forward direc-
tion 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
following items.
n Confirm that the signal from the linear encoder is being received normally.
n Make sure that the forward direction of the Linear Servomotor and the count-up direc-
tion 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 Servomotor may not operate or it may run out of control.
Always confirm these items before you operate the motor.
