DMC-40x0 Command Reference #LIMSWI • 151
#LIMSWI
FUNCTION: Limit switch automatic subroutine
DESCRIPTION:
Without #LIMSWI defined, the controller will effectively issue the STn on the axis when it’s limit
switch is tripped. With #LIMSWI defined, the axis is still stopped, and in addition, code is
executed. #LIMSWI is most commonly used to turn the motor off when a limit switch is
tripped (see example below). For #LIMSWI to run, the switch corresponding to the direction
of motion must be tripped (forward limit switch for positive motion and negative limit switch
for negative motion). #LIMSWI interrupts thread 0 when it runs.
