Rotary Table with “Calibrated” Stop Positions

Home the axis, wait for an input and then index to 3 different stop positions (absolute positions), wait for an input between

indexes. The InPosn output function could be assigned to an output to indicate when the axis has completed the index and the

following error is less than a specified amount. Since the indexes are to absolute positions they can be adjusted to “calibrate”

the stop positions to account for mechanical non-linearity in the particular rotary table. A rollover position of 360.00 degrees

would be entered into the setup view so that the system would take the shortest path (across the rollover) during the last move.

Flying Cutoff/Shear

Flying cutoff or flying shear application to perform synchronized out and return indexes which repeat every 100 inches of

master travel.

Part Length = 100 inches

Knife Travel Distance = 20 inches

PLS.0 is used to initiate Index.0 every 100 inches. PLS.0 has an “ON” point at 0.000 inches and an “OFF” point at 90.000

inches. PLS.0 has a rollover position of 100.000 inches. The rollover position is used to set the part length. The source for

PLS.0 is the master axis. The PLS is configured in the PLS view. The PLS output does not necessarily need to be connected

to an output line on the drive or module because it is used within the program to initiate an index.

An Index PLS is used to fire the cutoff knife. The Index PLS is connected to Output #1 on the drive. The Index PLS is

configured in the index setup view. The Index PLS for Index.1 has an “ON” point 2.000 inches into the index and an “OFF”

point 18 inches into the index.

Home.0.Initiate ‘Sensor,Offset=1.000in,Vel=-5.0 in/s

PLS.0.Enable=ON ‘Turn on PLS.0

Wait For DriveInput.1=ON ‘Input 1 is used as a “hold” input.

If PLS.0.Status = ON Then ‘If the PLS is already on you are too late.
