Change of direction of rotation for connection at input CDATA−XIN
(see also chapter 3.2.3.2)
)
Note!
The direction of rotation of an absolute shaft encoder connected to input
CDATA−XIN (single−turn or programmable multi−turn) can only be reversed by
changing the attachment.
3.2.3.5 Profile changeover in the middle of the motion profile
By means of 5th order polynomials you can implement a jerk−free, path−controlled clutch function.
For this, motion profiles have to be changed over in the middle of a profile.
Requirements for trouble−free clutch function:
l The function can only be implemented with the absolute data model.
l The profiles between which the changeover is effected must be structured in the same
manner:
– Same clock pulse lengths in X direction
– Same number of interpolation points
– Same distribution of the interpolation points
– Same lift at the changeover point
Activation of the clutch function:
l Set CDATA−SEL−CAM−MODE = HIGH.
3.2.3.6 Activation of profiles stored in the controller
The 9300 cam profiler provides the possibility to use one or several stored profiles for processing a
product.
Depending on the profile(s) selected, the stored data is assigned to the actual master value position
and output.
