9 MAJOR POSITIONING CONTROL
9.2.8 3-axis fixed-feed control (interpolation)
In "3-axis fixed-feed control" ("
Da.2
Control system" = fixed-feed 3), three motors are
used to carry out fixed-feed control in a linear path while carrying out interpolation for
the axis directions set in each axis.
In fixed-feed control, any remainder of the movement amount designated in the
positioning data is rounded down if less than that required for control accuracy to
output the same amount of pulses. (The remainder of the movement amount with an
accuracy below the control accuracy does not affect the regular controls.)
(Refer to Section 9.1.6 "Interpolation control" for details on interpolation control.)
