MC/WK
[Function]
This signal selects a machine coordinate system or a modal workpiece coordinate system on which
positioning is done in manual random feed mode.
[Operation]
The "MC/WK (CXS5)" signal becomes valid when the "ABS/INC (CXS6)" signal explained later is
OFF in manual random feed mode.
(1) When the "MC/WK" signal is OFF:
"Manual random feed nth axis movement data" set in a file register (R) is used for positioning on
the machine coordinate system.
Amount of motion =
Manual random feed nth movement data- Coordinate value on machine coordinate system
(2) When the MC/WK signal is ON:
"Manual random feed n-th axis movement data" set in a file register (R) is used for positioning
on the modal workpiece coordinate system.
Amount of motion =
Manual random feed nth movement data-

ABS/INC
[Function]
This signal selects whether motion data is given in an absolute value or incremental value for
manual random feed.
[Operation]
(1) When the ABS/INC (CXS6) signal is OFF:
"Manual random feed n-th axis movement data" set in a file register (R) is handled as an
absolute value. For details, see the "Descriptions on the MC/WK (CXS5)" signal explained
before.
(2) When the ABS/INC signal is ON:
"Manual random feed n-th axis movement data" set in a file register (R) is handled as a real
movement value.
