Automatic Rotary Shear
In the application of rotary shears, KNX5100C software provides four methods
to build rotary shear curves:
• Rotary shear - without sync zone
• Rotary shear - fixed sync zone
• Rotary shear - adjustable sync zone
• Rotary shear - printing machine
The difference between methods is in the phase interval of the master axis and
the slave axis in the same speed zone. Select different speed zones depending on
the machined tool type and the required motion behavior. The automatic rotary
shear with intermittent printing machine is a curve-specific creation method for
printing presses. Alternatively, application macros #6 and #7 can be used to create
the electronic cam curve of the flying shear.
Rotary Shear - Without Sync Zone
This method of creating E-Cam curve is only applicable to the sharp knife
application and is created by using KNX5100C software.
1.
Set the gear number (A) of the motor and the gear number (B) of the
cutter.
2.
Set the number of cutters based on the application.
3.
Set the diameter of cutter based on the application.
This value does not change if the number of cutters changed. The
KNX5100C software automatically calculates the perimeter.
4.
Set the diameter and single-turn pulse number of the master axis encoder.
Based on these two parameters, you can calculate the command resolution.
If the gear ratio of the master axis is known, then the diameter and single-
turn pulse number of encoder is no longer needed. You must directly input
the value of ID371 (P5.083) and ID372 (P5.084).
5.
Set the number of PUUs that the motor runs one revolution with the
electronic gear ratio (ID151 (P1.044) / ID152 (P1.045)).
6.
Set the length of cutting.
To prevent creating unreasonable rotary shear curves, the software
automatically limits the length by the ratio of the cutting length (L) to the
edge spacing (a): (R = L / a), R = 0.3…3.
