Function
DMC_SwitchSoftLimit controls the software limit switch. When Switch is TRUE and the instruction execution
is completed, the software limit switch turns ON. When Switch is FALSE and the instruction execution is
completed, the software limit switch turns OFF.
Also, users could set the switch by clicking Network Configuration-> Motion->Axis Configuration->General in
the software without using the instruction.
The maximum position and minimum position need be set through the software.
After the software limit switch is ON, an error will occur if the axis position which is being controlled by motion
instructions exceeds the software limit range.
