Programming

7.3.3.1

Activate skew angle transformation (TRAANG)

The oblique angle transformation (TRAANG) is activated in the part program or synchronized
action using the TRAANG statement.

<value> Meaning
0.0 The acceleration margin is determined by the NC depending on the angle of the
inclined axis and the acceleration capability of the inclined and the longitudinal axis
so that the same acceleration limitation results in the direction of the longitudinal axis
and of the associated perpendicular (virtual) axis.
> 0.0 Acceleration margin = <value> * (MD32300 $MA_MAX_AX_ACCEL of the longitudi‐
nal axis)
WARNING
No M code is output.
The values 0 to 6, 17 and 30 are not output to the PLC.
