Spindle Index pulse and safty.

[ellik]

I have been wondering if there is a way to add an extra safety option in Mach in case the spindle does not turn on or does stop for one reason or the other using the spindle index pulse. If Mach has the spindle turned on but no index signals generated within a certain time interval an e-stop is raised stopping the system.

A "Spindle Inhibit" input signal could be beneficial as well, e.g. when using a probe one can have a 4 pin plug where 2 of the pins close the inhibit signal loop preventing the spindle to turn on and potentially damaging the probe, when plugged in.

Regards.

I had a macropump that would compare the commanded speed with the true speed and if not within 10% it would E-Stop, unfortunately it wouldnt run properly with the ModBUS I had for my PLC so I never used it. Now I dont need it anyway as I have a Servo on the spindle and if it faults then Mach faults.
