s = Slot number for the SLC Servo Module

01 – Homing to a
Marker, (10=0, 9=1),

Specifies that the axis is homed by moving to a
marker. The two parameters,

Final Move to Which

Marker? and Final Move to Marker?, specify which marker
to move to and whether the final move to the marker is
required or not.

10 – Homing to a Limit
Switch (10=1, 9=0),

Specifies that the axis is homed only using a limit
switch and markers are not used for homing. This
can result in a final home position that can be
inaccurate as markers are not used for homing.

11 – Homing to a Limit
Switch and Marker
(10=1, 9=1)

Specifies that the axis is homed using both the limit
switch and marker. When the limit switch is found
and a move is made to go off the limit switch, the
home sequence is identical to home to marker. As a
result, the two parameters,

Final Move to Which

Marker? and Final Move to Marker?, specify which marker
to move to and whether the final move to the marker is
required or not.

Marker Nearest Start Position (0) configures the axis
to move to the nearest marker from the start position
of the final move to the marker of the homing
sequence. Move to one (1) revolution of the
feedback device in the direction and at the speed
specified by the Home Axis command, then stop. The
axis then moves to the nearest marker.

Final Move to Marker?
(Homing)

M0:s.0/12

Yes (1) / No (0)

Yes

If set, the axis performs the final move to the marker
specified by

Final Move to Which Marker?. Otherwise,

the axis does not perform the final move to the marker
specified by

Final Move to Which Marker?, but instead

assigns the current position of the axis to the configured
Home Position ± the distance to the nearest marker. Refer
to

Homing to a Limit Switch in this manual for alternate

usage.

Enable Incremental
Position Command
(System)

M0:s.0/13

Yes (1) / No (0)

If the incremental position command is enabled, the
SLC Servo Module does not execute blend profile
moves and the appropriate error messages are
generated when a profile move is commanded.
