Registration mark on PMAC

[jcarrasco]

Hello, 

I want to implement a register control in a packaging machine with PMAC VMEbus controller. I would like to know if there is a special function in the PMAC programming to do it or any alternative way.

Please describe in greater detail what you mean by “register control”?

Hell Mr. Milici

Usually, printing and packaging machines have to  be re-registered due to stretching, slippage, or uneven spacing of the material.

A registration sensor is  used to capture the positon of a mark in the film, so it can be used for position control and to coordinate the separation and cutting of webs of packaing material. 

I was wondering if the PMAC has any function to do that.

Possibly you could use your "registration sensor" as a home input, depending on the electrical characteristic of your sensor.
If it's similar to a limit switch, that approach could be used.

Of course, it would also be possible to implement a PLC to execute the actions for that.
For example, move then motors until find your mark.

Also...see the section of the User Manual titled "SYNCHRONIZING POWER PMAC TO EXTERNAL EVENTS"

Several techniques are described there for doing the kind of thing you are describing.

Thank Mr. Martins and Mr.Barnett for your sugestions. I will have look to the documentation and let you know.
