Read the encoder value of the gray code encoder with a sequence program, and update "[Cd.325] Input value for
synchronous encoder via device (R: D42326+16n, D42327+16n/Q: D14826+10n, D14827+10n)" of the synchronous encoder
axis 4 at every time.

The synchronous encoder current value that is restored for the synchronous encoder connection gets restored into a
converted value from the following range based on the synchronous encoder travel value on disconnection.

Multiple CPU advanced synchronous control
Used to operate the servo input axis, command generation axis, and synchronous encoder axis of the master CPU as the
synchronous encoder axis.
By setting the input axis type of the master CPU in "[Pr.320] Synchronous encoder axis type" to the following, the change from
the master CPU is used as the input value for operating the synchronous encoder axis.
Refer to selection of slave CPU input axis type for details on the setting method. (Page 191 Selection of slave CPU input

Range of restored synchronous encoder current value
- (Resolution of synchronous encoder via device ÷ 2) to + (Resolution of synchronous encoder via
device ÷ 2 - 1)[pulse]
*: If the resolution of a synchronous encoder via device is an odd number, round down a negative
value after the decimal point, round up a positive value after decimal point.
