LT — Extended list of the trajectory
Usage IMM PGM MIP
Syntax xxLT
Parameters
Description xx [int] — Element number.
Range xx — 1 to 100.
Units xx — None.
Defaults xx Missing: 0.
Out of range: Error C.
Description This command retrieves from the controller the extended form of an ele-
ment of trajectory.
NOTE
When the element number is 0 or absent, all elements of the trajectory
will be listed.
Returns The returned value is dependent of the element type and is as follow, when
element is:
• ƒ (LX):
xxLTaa, X=xx, Y=yy, A=tt
• ƒ (LY): xxLTbb, X=xx, Y=yy, A=tt
• ƒ (MX, MY): xxLTcc, X=xx, Y=yy, A=tt
• ƒ (CX, CY): xxLTdd, X=xx, Y=yy, A=tt, R=rr, B=ss, S=ww
• ƒ (CR, CA): xxLTee, X=xx, Y=yy, A=tt, R=rr, B=ss, S=ww
where:
aa — Line (x, θ ).
bb — Line (y,
θ
).
cc — Line (x, y).
dd — Arc (x, y).
ee — Arc (r, θ ).
xx — X end position of the element.
yy — Y end position of the element.
tt — Angle of the tangent at the end position.
rr — Radius of the circle.
ss — Start angle for a circle.
ww — Sweep angle for a circle.
Errors C — Parameter out of limits.
S — Communication time-out.
Rel. Commands XT — Tell number of elements in the trajectory.
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
).
1LT | Extended list of a trajectory.
1LT, Arc (r, θ ), X=10, Y=10, A=90, R=10, B=270, S=90
| Controller tells the built element.
