HardStop
This command is internally triggered when an electrical
problem is detected in one or both coils, leading to switch
off the H-bridges. If this problem is detected while the
motor is moving, the <StepLoss> flag is raised allowing
warning the Master that steps may have been lost at the
next GetStatus command. The Master for some safety
reasons can also issue a HardStop command.

ResetPosition
This command is provided to the circuit by the Master to
reset
ActPos
and
TagPos
registers, in order to allow a
positioning for an initialisation of the stepper motor
position.

ResetToDefaults
The Master provides this command to the circuit in order to
reset the whole Slave node into the initial state.
R
esetToDefaults
will for instance
overload the RAM
with the Reset state of the Registers parameters. This is
another way for the Master to initialise a slave node in case
of emergency, or simply to refresh the RAM content.
