_LR*
FUNCTION: Reverse Limit Switch Operand (Keyword)
DESCRIPTION:
*The _LR operand contains the state of the reverse limit switch.
Note: This is not a command.
NOTE: This operand is affected by the configuration of the limit switches set by the
command CN:
For CN-1:
_LRx = 1 when the limit switch input is inactive*
_LRx = 0 when the limit switch input is active*
For CN 1:
_LRx = 0 when the limit switch input is inactive*
_LRx = 1 when the limit switch input is active*
* The term “active” refers to the condition when at least 1 ma of current is flowing through
the input circuitry. The input circuitry can be configured to sink or source current to
become active. See Chapter 3 of product manual for further details.
EXAMPLES:
MG _LR Display the status of the reverse limit switch
JP#A,_LR=0 Jump to label, #A, when reverse limit switch is activated
*This is an Operand – Not a command.
