EDSVS9332K−EXT EN 4.0

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.
