_LF
FUNCTION: Forward Limit Switch Operand
DESCRIPTION:
The _LF operand contains the state of the forward limit switch for the specified axis.
The operand is specified as: _LFn where n is the specified axis.
Note: This operand is affected by the configuration of the limit switches set by the command CN:
For CN -1:
_LFn = 1 when the limit switch input is inactive*
_LFn = 0 when the limit switch input is active*
For CN 1:
_LFn = 0 when the limit switch input is inactive*
_LFn = 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 in the User's Manual for further details.
