How to set delay for spindle ramp down? (Resolved)

Post by carboncymbal »

I looked around for this couldn't find the information. I'm sure that I overlooked it somewhere. Could someone please tell me how I can set the delay for the M5 (Spindle off) command? For example, if my spindle takes 5 seconds to ramp down from 24,000 rpms, how can I ensure that the machine pauses for long enough before attempting a tool change? I do not have any additional inputs that I can spare to detect zero speed from the VFD.

Thanks,
Clay

Gary beat me to it.....again, just add G4 P5 in your M6 macro right after the M5 command line.

M5 ;Turn off spindle
G4 P5 ;pause for 5 seconds (where "5" is the number of seconds you want to pause)
