Today was a good day for the most part. I got the floater, draw bar, and 42 new washers put in. Cleaned all the top end up. Tightened the orientation cylinder and organized the wiring and hoses. Lots of loose brackets and parts on this machine. Motor tension cable and bracket was all loose and missing bolts so I fixed that and adjusted it. I wonder who their maintenance company / person was?
I got tired of pushing the solenoid button constantly and just wrote a program to cycle the lube pump for ON 2 minutes, OFF 30 seconds and just let it run and do it's thing all morning while I jacked with everything else. Finally purged all the lines and had a good coat of oil everywhere. Oh, I used an Arduino with Relay shield to cycle the solenoid valve.
I was having issues when doing a M19. In low speed, it would orientate perfectly, but in high gear, it would move too fast and just rock back and forth 1/4 turn on each side of the magnet. The Diagnostics was showing the Orientation Switch (hall sensor) was indeed registering, but the motor kept overshooting it. I finally turned the factory orientation rpm factor down from 10 to 5 and now it slowly moves over and locks in perfect each time. I'm not sure why the factory setting wasn't or isn't working.
Still looking for detailed information on the Fadal Baldor VFD parameters. I played with lots of VFD's but I take it this one is custom done for Fadal or I just not familiar with Baldor.
RPM is kind of off. I have to do some sort of tuning to try and get the low speed and high speed RPM's a little closer to what I tell it since it will affect some of my tapping feeds. I don't understand why we have an orientation hall sensor on the spindle pulley but nobody is reading it for actual RPM? That would be perfect for RPM PID control and also fro tapping feeds with a T/C tap holder.
Later. Happy new years to all.
