3. MANUAL OPERATION
325
In manual handle feed or jog feed, the following types of feed operations
are enabled in addition to the conventional feed operation along a
specified single axis (X--axis, Y--axis, Z--axis, and so forth) based on
simultaneous 1--axis control:
D Feed along a tilted straight line in the XY plane (M series) or ZX plane
(T series) based on simultaneous 2--axis control (linear feed)
D Feed along a circle in the XY plane (M series) or ZX plane (T series)
based on simultaneous 2--axis control (circular feed)

NOTE
The X-- axis and Y--axis (M series) or Z-- axis and X-- axis (T
series) must be the first contro lled axis and second
controlled axis, respectively. The following description
applies to the X-- Y plane for the M Series. For the T Series,
read the X--Y plane as the Z--X plane.
A line or circle definition is not required for axial feed. For linear or
circular feed, however, a line and circle must be defined, using the
interface described later. (For circular feed, for example, the center and
radius of the circle must also be specified.)
The R area of the PMC--SB/SC is used partly for line and circle
definitions. Set the necessary data in this area, using the PMC or macro
executor. See the following descriptions for what data is to be set at each
address.
