[Pr.320] Synchronous encoder axis type
Set the synchronous encoder type to be generated of the input value for the synchronous encoder axis.
Setting value
0: Invalid
1: Incremental synchronous encoder
101 to 116: Synchronous encoder via servo
amplifier
(Connectable servo amplifier: Axis 1 to axis 16)
201: Synchronous encoder via CPU
[Pr.321] Synchronous encoder axis unit setting
Set the position and speed unit of the synchronous encoder axis. Refer to the following for details.
Page 32 Units for the synchronous encoder axis
[Pr.322] Synchronous encoder axis unit conversion: Numerator
The input movement amount 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.

The movement amount corresponding to "[Pr.323] Synchronous encoder axis unit conversion: Denominator" is set in "[Pr.322]
Synchronous encoder axis unit conversion: Numerator" in synchronous encoder axis position units (Page 32
Synchronous encoder axis position units). The input movement amount can be reversed by the setting negative values.
Set "[Pr.323] Synchronous encoder axis unit conversion: Denominator" based on encoder pulse units from the synchronous
encoder. Set a value within the range from 1 to 2147483647.

[Pr.324] Synchronous encoder axis length per cycle
Set the length per cycle for the synchronous encoder axis current value per cycle.
The current value of synchronous encoder axis is stored in "[Md.321] Synchronous encoder axis current value per cycle" at
ring counter based on the setting value.
The unit settings are in synchronous encoder axis position units (Page 32 Synchronous encoder axis position units).
Set a value within the range from 1 to 2147483647.
Details
Synchronous encoder axis is invalid.
Generate the input value based on the incremental synchronous encoder input.
Generate the input value based on the synchronous encoder input via servo amplifier connected to the
specified servo amplifier (axis 1 to axis 16).
Generate the input value with the value set in the buffer memory by the CPU module as the encoder value.
