3.4.4 Camming
Camming is characterized by adynamic ratio between the leading and following
axes, and by the phase shift. The transmission ratio is described by a cam disk
(transfer function).
Scaling and offset of the cam disk used is possible on both the leading axis and the
following axis. This allows an individual adjustment of the cam disk definition and
range.
Synchronization to a position within the cam is also possible, as is a cam
changeover at the end of a currently active cam.
Response characteristics
The transmission characteristics of camming are determined by a cam disk (y =
f(x)).
Scaling and Offset
The scaling and offset of the cam function for camming can be set both at the
leading axis and at the following axis by means of the technology function for cam
synchronization. The configured cam disk is not modified by the call of the
"MC_CamIn" technology function.
