Syntax
FENDNORM
G62 G41
G621
Meaning
FENDNORM: Automatic corner deceleration OFF
G62: Corner deceleration at inside corners when tool radius compensation is active
G621: Corner deceleration at all corners when tool radius compensation is active
G62 only acts on inner corners with active tool radius compensation G41/G42 and active
continuous-path mode G64/G641.
The corner is approached at a reduced feedrate, which is calculated as follows:
F * (override for feed rate reduction) * feed rate override
The maximum possible feed rate reduction is attained at the precise point where the tool is to
change directions at the corner, with reference to the center path.
G621 acts analogously to G62 at each corner of the axes defined using FGROUP.
3.7.11 Programmable end of motion criteria (FINEA, COARSEA, IPOENDA, IPOBRKA,
ADISPOSA)
Similar to the block change criterion for path interpolation (G601, G602, and G603) it is also
possible to program the end-of-motion criterion for single-axis interpolation in a part program or
in synchronized actions for command/PLC axes.
The end-of-motion criterion set will affect how quickly or slowly part program blocks and
technology cycle blocks with single-axis movements are completed. The same applies for PLC
via FC15/16/18.
