(b) Synchronous encoder axis unit conversion gear setting
The input travel distance of the synchronous encoder is in encoder pulse units. You can convert the
unit into a desired unit through unit conversation by setting [Cam control data No. 15 Synchronous
encoder axis unit conversion: Numerator] and [Cam control data No. 16 Synchronous encoder axis
unit conversion: Denominator].
Set [Cam control data No. 15] and [Cam control data No. 16] according to the control target
machine.

The travel distance (number of pulses) set in [Cam control data No. 16] is set in [Cam control data
No. 15] in synchronous encoder axis position units.
Set [Cam control data No. 16] in encoder pulse units of the synchronous encoder.
