Hi,
applied to HLFB+ and HLFB- needs to attached to GND on an input terminal of my B.O.B. in order for my motors to enable.
No HLFB is the fault signal. There are a few options how you program when the HLFB operates inside the servo but the most useful
one is 'In Position'. So when the servo is in position and correctly following the input commands the signal will be active.
Thus if you have 5-24V on HLFB+ under normal circumstances 5-24V will appear on HLFB-. If however the servo can't keep up
with its commanded input then HLFB- will be 0V.
You will want Mach to monitor this signal and if the servo faults then it will probably Estop. You could use a Brain in Mach3 or you could
attach it to a limit switch so that if the servo faults Mach equates that with a limit switch event and turns off.
To enable your servo attach 5-24V to Enable+ and 0V to Enable-.
