Here's my setup:
I have a KBIC board controlling the spindle speed. This is currently set up with a pot on the p1, p2 and p3 pins, but for testing I set up the G540 connected as seen here: http://pminmo.com/g540-vfd (the version straight from the G540 to the KBIC board) I have a spindle on/off relay set up on parallel pin 17 for start top (works just fine). What I would like to do is press the start button for the spindle (I'm using Axis by the way), have the spindle start at a set speed and I can press the + and - buttons from here to control the actual RPM of the spindle, or even enter a value into a field to command a specific RPM. I'll do this in the Gcode later on.. but this is just for testing right now. I'd also like to have a display in Axis that shows the "commanded" RPM as well for reference (later I'll attach a Tach that will send data back to the HAL from an Arduino controller). What happens now.... I press the spindle start (the little circular arrow), the spindle starts at a slow speed. I can press the + and - buttons in the interface all I want and nothing changes. I've looked at the HAL configuration and pins while I'm testing and since I'm not sure what I'm looking for, or what I'm missing.. I don't know if it's right or wrong. The following is my .hal file. I set it up according to the spindle control examples on the EMC web site.. but something is still not right. Not knowing exactly how everything in the HAL goes together is probably most of the issue here as I can't diagnose what's right/wrong in the HAL. :( I've tried tweaking values from some of the clues I've run across.. but again.. I don't "know" what they're for so I should stop before I let out the magic smoke.. Maybe someone here can help me with it? What am I missing? Can someone point me in the right direction? Can anyone Help?
