Galil / Galil 2080 and E Stop
« on: April 23, 2010, 01:55:13 AM »
Hello,
First post here. I have recently aquired a set of Galil equipment for my cnc conversion. I'm working on the cnc conversion of a Bridgport Clone. This requires realtively heavy motors. I"m allready building myself the controllers (UHU servo controllers) that are controlled by step/dir.
I have allready installed a demo version of Mach and have the controller working and registered in Mach. The documentation is excellent and will give me most of the info I need to get things working. There are however a couple of question that remain.
- How do I hook up an estop circuit to Mach via the Galil. Due to the size of the motors and the resulting damage if something would go wrong, I have chosen to hardwire the entire estop ciruit using a Pilz Pnoz Estop relais. This means that all components (Inverters, servo drives, etc) are able to trip the e stop relais. This relais then stops motion and with a timed delay, powers down the complete powersection and discharges the capacitor bank. How can connect the signal (24V) to the Galil and how can I let the Galil tell Mach3 that there is an e stop?
- Does the charge pump still work?
- How safe are the limit switches in the Galil? Can I hook up the limit switches to the Galil and have it output a signal to my e stop circuit or do I need to "split" the signal. Or is the Galil safe enough to allow the limit switches to be omitted from the e stop circuit so that I can clear the limit switch using the Galil?
- I'd like to use an MPG to control the mill in "manual" mode. Can I use a selectorswitch to increase or decrease the resolution?
I hope someone here can shed some light.
