170 ● RE DMC-1400 Series Command Reference
RE
FUNCTION: Return from Error Routine
DESCRIPTION:
The RE command is used to end a position error handling subroutine or limit switch handling
subroutine. The error handling subroutine begins with the #POSERR label. The limit
switch handling subroutine begins with the #LIMSWI. An RE at the end of these
routines causes a return to the main program. Care should be taken to be sure the error or
limit switch conditions no longer occur to avoid re-entering the subroutines. If the
program sequencer was waiting for a trippoint to occur, prior to the error interrupt, the
trippoint condition is preserved on the return to the program if RE1 is used. RE0 clears
the trippoint. To avoid returning to the main program on an interrupt, use the ZS
command to zero the subroutine stack. No RE needed after ZS.
ARGUMENTS: RE n where
n = 0 or 1
0 clears the interrupted trippoint
1 restores state of trippoint

HINT: An applications program must be executing for the #LIMSWI and #POSERR subroutines to
function.
