Input possibilities
End point coordinates
Soft keys
Known data
Cartesian coordinates X and Y
Polar coordinates referenced to FPOL
Example
7 FPOL X+20 Y+30
8 FL IX+10 Y+20 RR F100
9 FCT PR+15 IPA+30 DR+ R15
Direction and length of contour elements
Soft keys
Known data
Length of a straight line
Gradient angle of a straight line
Chord length LEN of an arc
Gradient angle AN of an entry tangent
Center angle of an arc
NOTICE
Danger of collision!
Incremental gradient angles
IAN
are referenced by the control to
the direction of the previous traversing block. NC programs from
previous control models (including iTNC 530) are not compatible.
There is danger of collision during the execution of imported NC
programs!
Check the sequence and contour with the aid of the graphic
simulation
Adapt imported NC programs if required
Example
27 FLT X+25 LEN 12.5 AN+35 RL F200
28 FC DR+ R6 LEN 10 AN-45
29 FCT DR- R15 LEN 15
