Programming
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 setup screen. 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 screen. 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.

Synchronized Jog with Manual Phase Adjustment
The motor controls a lugged conveyor belt which is synchronized to another lugged conveyor belt. Jog.0 is configured as a “Synchronized” jog using the setup software. The program first homes the follower and then waits for an input from a sensor on the master axis lugs. When the input comes on the follower starts the synchronized jog. If the home is setup correctly the follower will be in perfect phase when it gets up to speed. If the follower gets out of phase with the master the operator can manually bring the it back into phase using “Advance” and “Retard” inputs. The program adjusts the phase of the follower axis by adjusting the jog velocity (Jog.0.Vel) when the operator hits one of the phasing inputs.
