"dummy" applications program is being executed.

Now, when a forward limit switch occurs on the X axis, the #LIMSWI subroutine will be
executed.
Notes regarding the #LIMSWI Routine:
1)
The RE command is used to return from the #LIMSWI subroutine.
2)
The #LIMSWI subroutine will be re-executed if the limit switch remains active.
The #LIMSWI routine is only executed when the motor is being commanded to move.

Now, if the position error on the X axis exceeds that specified by the ER command, the #POSERR
routine will execute.
NOTE: The RE command is used to return from the #POSERR subroutine
NOTE: The #POSERR routine will continue to be executed until the position error is cleared (is
less than the ER limit).
