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.
