[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.
