1.5.4 Rotary Axis Roll Over
Overview
The roll-over function prevents coordinates for the rotation axis from
overflowing. The roll-over function is enabled by setting parameter
ROAx (No. 1008#0) to 1.
For an incremental command, the tool moves the angle specified in
the command. For an absolute command, the coordinates after the tool
has moved are values rounded by the angle corresponding to one
rotation set in parameter No. 1260. The tool moves in the direction in
which the final coordinates are closest when parameter RABx (No.
1008#1) is set to 0. Displayed values for relative coordinates are also
rounded by the angle corresponding to one rotation when parameter
RRLx (No. 1008#2) is set to 1.

ROSx ROTx Meaning
0 0
Linear axis
(1) Inch/metric conversion is done.
(2) All coordinate values are linear axis type. (Is not rounded in 0 to 360
°)
(3) Stored pitch error compensation is linear axis type (Refer to parameter No.3624)
0 1
Rotation axis (A type)
(1) Inch/metric conversion is not done.
(2) Machine coordinate values are rounded in 0 to 360
°. Absolute coordinate values are rounded or not
rounded by parameter No.1008#0(ROAx) and #2(RRLx).
(3) Stored pitch error compensation is the rotation type. (Refer to parameter No.3624)
(4) Automatic reference position return (G28, G30) is done in the reference position return direction and the
move amount does not exceed one rotation.
1 1
Rotation axis (B type)
(1) Inch/metric conversion, absolute coordinate values and relative coordinate values are not done.
(2) Machine coordinate values, absolute coordinate values and relative coordinate values are linear axis
type. (Is not rounded in 0 to 360
°).
(3) Stored pitch error compensation is linear axis type (Refer to parameter No.3624)
(4) Cannot be used with the rotation axis roll over function and the index table indexing function (M series)
Except for the above. Setting is invalid (unused)
