0 0 0 General Purpose Input
The input is not used in any of the functions of the
SMD23E2 or SMD24E2, but it’s status is reported in the
Network Data. This allows the input to be used as a dis
-
crete DC input to the host controller.
0 0 1 CW Limit Input defines the mechanical end point for CW motion.
0 1 0 CCW Limit Input defines the mechanical end point for CCW motion.
0 1 1 Start Indexed Move
Starts the move that is currently located in the output reg-
isters.

Capture Encoder Value
When the encoder is enabled on an SMD23E2 or
SMD24E2, the encoder position value is captured when
-
ever this input transitions. An inactive-to-active state tran-
sition will also trigger an Indexed Move if one is pending
in the SMD23E2 or SMD24E2.

Capture Encoder Value
When the encoder is enabled on an SMD23E2 or
SMD24E2, the encoder position value is captured when
the input triggers a controlled stop to a Jog or Registration
move.
1 0 1 Emergency Stop
All motion is immediately stopped when this input makes
an inactive-to-active transition.
1 1 0 Home Used to define the home position of the machine.
1 1 1 Invalid Combination This bit combination is reserved.
