Jon, yes, good point on brake. I also want to let the vfd to stop the spindle, and will use the brake for speed changes.

Sorry, flip-flop. a mechanism that sets to one logic value on a particular trigger, and stays in that state until a different trigger clears it. In hal, that is the flipflop component, for more info use : man flipflop on your EMC machine. In this case, you would not use the D or clk input, only the set and reset inputs and the out output. I don't use the brake, except when changing tools. I let the VFD do the braking. But, if your brake is pneumatic, you might need the solenoid valve hooked up anyway for tool changes.
