Just learning and thinking about possible catastrophes. (I callem cat-a$$-trophys)
1995 Fadal 4020HT with 88HS (1400-4 board) control, 10k spindle, rigid tap, TSC.
I could see a couple different things happening... and I realize the damage that occurs is variable depending on whats in the spindle, and whats youre doing... but my question is really more about what the control sees, and then does.
So, for the sake of an example... No tool in the spindle, not cutting anything, running a program for the fun of watching the machine move on its own.... and the spindle belt breaks. Maybe it wedges in and stops the spindle, or maybe it coasts down.
Does the control monitor the spindle speed and error out if it falls noticeably below the specified speed?
Does the control only monitor the spindle motor via the drive, so as long as the motor itself is spinning, the control thinks all is well?
Does the control notice a drop in spindle load and error out?
Or, does it not pay any attention and just keep on trucking through the program with the spindle off?
Just trying to wrap my head around what the control might do. I guess some of it has to do with planning maintenance, change a belt when it breaks, or a more proactive approach of changing it every X number of hours of spindle on time.
Thanks in advance.
