Create the curve for this alternative master clock distance and you will get ad
drift free curve operation.
the input field will become inactive, if motion sequences were already created
in the CamDesigner. The alternative clock distance can also be manipulated in
the header data mask of the CamDesigner.
Example:
Master: Direct-driven indexing table with 7 work stations;
Path/revolution = 360°
Reset distance = 360°
Slave: One of the work stations
Path/revolution = 360/7° master degree; cannot be displayed as clock resp.
master reset distance (drift)!
Better: alternative clock distance e.g. 360 slave degrees.
4 Selection of the signal source which is used as default value for the master
source (Input AXIS_REF_Local_Cam on the IEC block C3_MasterControl). An
entry is required.
You can choose between configured signal sources.
The source can be changed afterwards with the input master of the IEC block
C3_MasterControl.
5 The maximum speed is used as axis dimensioning for the display of the motion
profile as well as a limit value for the motion sequence..
At +/-10V as signal source, the value 10V is used (the entry field is
deactivated).
This value can also be manipulated in the header data mask of the
CamDesigner.
Please note: The value is converted into steps/min by the CamDesigner;
therefore a slight difference in this value caused by rounding is possible after
the return from the CamDesigner.
6 If the licence file is installed: Switching between Advanced and Basic version of
the CamDesigner.
7 Interpolation point reduction
deactivated: The curve is stored in equidistant interpolation points
(corresponding to the stated number of interpolation points)
Activation: The equidistant interpolation points are reduced (resulting in the
creation of not equidistant interpolation points).
The interpolation points are removed so that the resulting error is smaller than
the interpolation tolerance stated (linear interpolation is respected).
8 Interpolation tolerance (see 7).
9 Maximum number of interpolation points per curve. Value range 18..3600.
Without activated interpolation point reduction, a curve has this number of
interpolation points.
If the reduction is activated, the actual number of interpolation points may
(depending on the tolerance selected) be smaller. Please respect that this
value also constitutes the "basic grid" for the interpolation point reduction.
The number of interpolation points can also be manipulated in the header data
mask of the CamDesigner.
10 Here the dwell-to-dwell interpolation method is selected. The following motion
laws are possible in the BasicVersion of the CamDesigner:
• 3 Sloping Sine Line according to Helling-Bestehorn
• 4 5th order polynomial
• 5 Modified acceleration trapezoid
• 6 Modified Sine Line according to Neklutin
• 7 Simple sine (disadavantageous jerk)
• 11 11th order polynomial
• 12 Squared parabola (disadvantageous jerk)
• 28 8th order polynomial (disadvantgeous jerk)
• 30 low-noise cosine combination
• 31 3th order polynomial (disadvantgeous jerk)
• 32 4th order polynomial
• 33 6th order polynomial (disadvantgeous jerk)
• 34 7th order polynomial
• 38 mirrored sine
