MM4005 CR — Define radius for an
arc of circle = ƒ (CR, CA)
Usage  IMM  PGM  MIP
Syntax CRnn
Parameters
Description nn
[double] — Radius for an arc of circle.
Range nn — 1.0 E
-12
to 1.0 E
100
.
Units nn
— Defined motion units.
Defaults nn Missing: Error C.
Out of range: Error C.
Description This command defines to the controller the radius for an element of trajec-
tory of the type: arc of circle = ƒ (CR, CA). Unless the case of successively
builded with the same radius (r, θ) arcs, we have specified the radius by
this command every time before the CA command.
Returns None.
Errors C — Parameter out of limits.
V — Too long trajectory.
] — Trajectory: Arc (r,
θ) radius is too small.
^ — Trajectory: Arc (r,
θ) radius is too big.
e — Trajectory: Units not translationnal or not identical.
Rel. Commands CA — Define sweep angle and build an arc of circle = ƒ (CR, CA).
XE — Tell the last element.
Example NT | Clear trajectory.
CR10 | Define radius of an arc of circle = ƒ (r, θ).
CA90 | Define sweep angle an build an arc of circle = ƒ (r, θ).
XE | Tell last element.
XE, Arc (r,
θ), 10, 10, 90 | Controller tells the built element.
