It could be done that way, personally I would prefer to do it automatically to avoid human error.
The MO command could be burnt into the default parameters this will set the output AEN enable signals and used to turn the amps off, the brake could be activated this way also if the watch dog timer activates for a card failure, it also sets the AEN output.
Once Camsoft is running, the SH command turns the axis on and brake off.
This could also be integrated with the E-Stop circuit, either hardware, software or both.
