Hi all,
I have a question regarding the spindle speed setting in EMC.
Is it possible to get the required spindle speed as a digital value out of EMC to apply some logic to it either for instructing the operator or set the gearbox automatically?
In my case, I have a CNC lathe form 1977 with dual speed motor, motor controlled variator gear and a fixed reduction gear box. I would like to control these elements with EMC.
The same problem appears if you have to change the gears manually and you like to prompt the operator to change gears and let it acknowledge.
Any idea how to do this in EMC?
Regards
Tom

Is another part of the puzzle, I suspect.
For the manual version, I would use a custom M-code before the spindle speed request in the G-code to bring up a prompt in a programming language of my choice.

There is a HAL component for this.In my case, I have a CNC lathe form 1977 with dual speed motor, motor controlled variator gear and a fixed reduction gear box. I would like to control these elements with EMC.
