CSMIO IP-M how to connect emergency stop ... help please

[JAZZCNC]

See new drawing.

Regards the Limit switches I just want to make you aware that can use just one switch that moves with the axis and sense targets at each end of travel. This lowers the number of switches required to one for each axis and less wiring required which means lower chance of faults.

Each switch can also share the homing and limit switch dutys.
.If want to use this method then wire limits like in my first drawing. Set Limits and homes for each axis to same pin number in mach3 and then go to general config and turn off Home SW safety option.

In this new drawing the VFD is stopped if E-stop occurs. Also VFD will tell the controller if VFD faults. For this to work you will need to enable Spindle fault detection and set the Input # used.
