(1) Synchronous encoder axis type
The following 2 types of synchronous encoders can be used for the synchronous
encoder axis.
Refer to Section 5.3.2 for the setting method for each synchronous encoder axis.

(2) Control method for synchronous encoder axis
The following controls can be executed for the synchronous encoder axis by
using [Rq.320] Synchronous encoder axis control request (M11601+4n) and
[Cd.321] Synchronous encoder axis control method (D14823+10n).

(3) Units for the synchronous encoder axis
The position units and speed units for the synchronous encoder axis are shown
below for the setting of [Pr.321] Synchronous encoder axis unit setting.

The synchronous encoder (P1 to 12) controlled by Motion CPU is used as the
synchronous encoder axis.
The encoder value is loaded via Motion CPU device.
Used to operate a gray code encoder that is connected to the input module as a
synchronous encoder axis.
[Md.320] Synchronous encoder axis current value (D13240+20n, D13241+20n)
and [Md.321] Synchronous encoder axis current value per cycle (D13242+20n,
D13243+20n) are changed based on the setting of [Cd.322] Synchronous
encoder axis current value setting address (D14824+10n, D14825+10n).
Input from the synchronous encoder is disabled.
Input from the synchronous encoder is enabled.
