12. APPLICATION OF FUNCTIONS
(a) Relation among the main shaft input axis, position data unit, and feed length multiplication setting
The parameters used to set the position data unit and feed length multiplication differ depending on
the setting of [Cam control data No. 30 Main shaft input axis selection].

(b) Synchronous encoder axis unit conversion gear setting
The input travel amount 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.
Synchronous encoder
axis travel distance
(after unit conversion)
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.
