MM4005 CA — Define sweep angle and build an
arc of circle = ƒ (CR, CA)
Usage IMM PGM MIP
Syntax CAnn
Parameters
Description nn
[double] — Sweep angle for an arc of circle.
Range nn — -1.7 E
304
to -1.0 E
-12
.
and 1.0 E
-12
to 1.7 E
304
.
Units nn — Defined motion units.
Defaults nn Missing: Error C.
Description This command defines to the controller the sweep angle and tells to the
controller to build an element of trajectory of the type:
Arc of circle = ƒ(CR, CA).
NOTE
The convention for the sweep angle is the following:
• Sweep angle > 0 then it is used as Counter Clock Wise.
• Sweep angle < 0 then it is used as Clock Wise.
Returns
None.
Errors C — Parameter out of limits
H — Calculation overflow.
V — Too long trajectory.
\ — Type error (arc expected).
] — Trajectory: Arc (r,
θ) radius is too small.
^ — Trajectory: Arc (r,
θ) radius is too big.
_ — Trajectory: Arc (r,
θ) sweep angle is too small.
Rel. Commands CR — Define radius for 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 | Build an arc of circle = ƒ (r = 10 units, θ = 90°).
CA480 | Build an arc of circle = ƒ (r = 10 units, θ = 480°).
XE | Tell last element.
XE, Arc (r,
θ), 10, 10, 90 | Controller tells the built element.
