Radius Specification
Axis name: J01 to J32
Note (1) Word data is extended to long word data with a sign in the MC Unit.
(2) Figures below the decimal point are to be omitted.
(3) The actual value is determined by the setting value of the parameter
[P5AA02: Position command decimal point position].
(4) The actual value is determined by the setting value of the parameter
[P00M10: Interpolation feed decimal point position].
Description • The MOVEC command executes positioning with circular interpolation at
the speed specified with [interpolation feed rate] to the position specified
by [horizontal axis position command value] and [vertical axis position
command value].
• The rotation direction is clockwise when Q = 1, and counter-clockwise
when Q = -1.
• The circular arc center and radius are specified either by the center value
or by the radius value.
• For the center position specification, [horizontal axis center command]
and [the vertical axis center command] are handled as shown below by
the parameter [P00004.bit01: Circular arc interpolation center position].
• When specifying the radius, [radius] is always treated as the distance to
be moved from the present position.
• The unit system of the horizontal axis is used for the radius.

P00004.01 Handling of I/J
0: (ABL specification
disabled) The value in I or J is always treated as the travel distance
from the present position.
1: (ABL specification
enabled) The value in I or J is treated as travel distance from spec-
ified position or present position depending on ABL/INC
specification.
