[Pr.320] Synchronous encoder axis type
Set the synchronous encoder type to be generated of the input value for the synchronous
encoder axis.
0: Invalid .........................................................Synchronous encoder axis is invalid.
1: Incremental synchronous encoder ...........Generate the input value based on the
101 to 116: Synchronous encoder via servo amplifier

(Note-1): The range from axis 1 to 2 is valid in the 2-axis module, from axis 1 to 4 is valid in the 4-axis module,
from axis 1 to 8 is valid in the 8-axis module, and from axis 1 to 16 is valid in the 16-axis module.
[Pr.321] Synchronous encoder axis unit setting
Set the position and speed unit of the synchronous encoder axis. Refer to Section 2.2.1 for
details.
[Pr.322] Synchronous encoder axis unit conversion: Numerator,
[Pr.323] Synchronous encoder axis unit conversion: Denominator
The input travel value of synchronous encoder is configured in encoder pulse units.
The units can be arbitrarily converted through unit conversation with setting [Pr.322] and
[Pr.323]. Set [Pr.322] and [Pr.323] according to the controlled machine.

synchronous encoder axis position units (Refer to Section 2.2.1).
The input travel value can be reversed by the setting negative values.
