I continue to work on my new tool change design, and in order for it to work, I need the logic to do things it is not (yet) designed to do. Having said that, I was hoping to get answers on a few things.
1) I think having a separate tool up and down IOs will help, but I am unclear on how this Type 2 Tool Tray logic works during a tool change. I would appreciate it if someone has an example of a tool tray that is controlled this way that they can share or link to. The document makes mention of a second valve controlled by Tool Changer - Output 5 (Tool Tray Down), but I don't have any experience beyond using a single solenoid and IO for an up/down action. Is this where a double 5/2 solenoid is used?
2) I have a number of 'creative' ways planned for forcing the Tool Tray to retract between tool pick-up - something I need to have happen for my design to work.
Currently the logic has the tool tray stay up until the new tool has been clamped and the spindle moves up.
My question is, if I force the tool tray to retract (between tool drop off and pickup), and the Tool Changer - Input 4 (Tool tray UP OK) then goes from HIGH to LOW, will the controller signal an error and stop the tool change cycle?
3) Related to #2 above, If I can get the Tool Tray Logic - Type 2 IOs to work, will calling for the Tool Tray to retract using the IOs #5, at a time when the tool change logic does not expect it to, cause an error?
I am working on assembly a mock-up of my design to better illustrate what I am trying to get the logic to do.
As always any help and insights are greatly appreciated.
