of home_mode control.
_8154_home_move
This function will cause the axis to perform a home return move
according to the _8164_set_home_config() function set-
tings. The direction of movement is determined by the sign of
velocity parameter (MaxVel). Since the stopping condition of
this function is determined by the home_mode setting, users
should take care in selecting the initial moving direction. Users
should also take care to handle conditions when the limit switch
is touched or other conditions that are possible causing the
axis to stop. For more detail description, see section 4.2.10
