1.13 Cam Profiling
Note: The following functionality applies only to OC950s with
Enhanced Firmware. Standard OC950s are are not capable of
cam profiling.
Definition
In the 950, a ‘cam’ is a cyclic, generally non-linear relationship
between master encoder position and slave (motor) position.
That is, the relationship between slave counts and master
counts is no longer a constant ratio, but changes as a function
of master counts. As in electronic gearing, once a ‘cam’ has
been made active, the program no longer needs to do anything
special to maintain it - the motion profile is repeated
indefinitely until the cam is deactivated.
In camming terminology, a master is typically an external
encoder. The encoder is wired into the SC950 encoder input
port (connector J4 pins 21-24). It is also possible to use the
SC950’s virtual (internal) encoder.
