9-2-5 Cam Tables
cam table start position The absolute position of the master axis that corresponds to the cam start point
(phase = 0).
master following dis-
tance
The master start distance where the slave axis starts cam operation represented as
either an absolute position or relative position. The relative position is based on the
cam start point position.
start mode A specification of whether to represent the master following distance as an absolute
position or relative position.
null cam data Cam data that can be set after the end point where the phase and displacement are 0.
connecting velocity The connecting velocity that is used to connect cam profile curves. The connecting
velocity cannot be specified for some curves.
connecting acceleration The acceleration rate that is used to connect cam profile curves. The connecting
acceleration cannot be specified for some curves.
phase pitch The width when dividing the cam profile curve by phases (horizontal axis). The points
after dividing the curve into the phase pitch correspond to the cam data in the cam
table. You must specify the phase pitch for each cam block.
