Software Stroke Limit

In the "software stroke limit function", an address is set as the movable range. Even if a movement command to the address
outside the setting range is issued, the command will not be executed. By not executing the command outside the movable
area, even if an incorrect command or unexpected operation occurs, the system will not operate out of the movable area and
damage to the machine can be prevented.
In the motion system, the "set position" and "feed machine position" are used as the addresses indicating the current value.
However, in the "software stroke limit function", which address is used to carry out the limit check is designated in
AxisName.Pr.SwStrokeLimit_Target.
