The OEM750X has two dedicated hardware end-of-travel
limits—clockwise (CW) and counterclockwise (CCW). When
you apply power to the OEM750X, these inputs are enabled—
the default active state is
high
. To test the OEM750X without
connecting the CW and CCW limits, you must disable the
limits with the
LD3
command. You can use the Limit Switch
Status Report (
RA
) and Input Status (
IS
) commands to moni-
tor the limits’ status, and the
OSA
command to change the
active level of the inputs. The figure represents a typical
configuration of these inputs.
