_8158_set_home_config:
Configures the home return mode, origin(ORG) and index sig-
nal(EZ) logic, EZ count, and ERC output options for the
home_move() function. Refer to section 4.2.10 for the setting
of home_mode control.
_8158_home_move:
This function will cause the axis to perform a home return move
according to the _8164_set_home_config() function settings.
The direction of movement is determined by the sign of velocity
parameter (MaxVel). Since the stopping condition of this func-
tion 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
