■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].

■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 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 machine to be controlled.
Synchronous encoder axis travel distance
(after unit conversion)
The travel distance in numbers 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.
