MANUAL RANDOM FEED
—
1ST AXIS MOVEMENT DATA
[Function]
This data specifies the amount of movement or positioning point in manual random feed mode.
[Operation]
"Manual random feed 1st axis movement data" is for the axis whose number is specified by
"Manual random feed 1st axis axis number (CX11~CX116)".
"Manual random feed 1st axis movement data" (R914, R915) means differently depending on the
statuses of the "MC/WK (CXS5)" and "ABS/INC (CXS6)" signals.
(1) When the ABS/INC (CXS6) signal is ON:
This file register (R914, R915) specifies the amount of movement (increment).
(2) When the "ABS/INC (CXS6)" signal is OFF, it depends on the status of the "MC/WK (CXS5)"
signal as follows:
1) When the MC/WK (CXS5) signal is OFF:
This file register (R914, R915) specifies a coordinate value (positioning point) of the
machine coordinate system.
2) When the MC/WK (CXS5) signal is ON:
This file register (R914, R915) specifies a coordinate value (positioning point) of the
modal workpiece coordinate system.
This file register (R914, R915) is written in binary notation with a sign. The unit of the specified
value matches that of data entered.
Ex.: When (R915, R914)=1 is specified in micro meter system, axis motion is one µm (at
incremental specification).
[Caution]
MANUAL RANDOM FEED 1ST AXIS MOVEMENT DATA forms a data item by R914 and R915 or
R1014 and R1015. Handle negative data carefully.

2ND AXIS MOVEMENT DATA
[Function] [Operation]
"Manual random feed 2nd axis movement data" is for the axis whose number is specified by
"Manual random feed 2nd axis axis number (CX21~CX216)."
The other conditions are the same as for "Manual random feed 1st axis movement data" explained
in the previous section.
