With palrameters 40 to 43, linear corrections of individual axes can be programmed. Correction either affects
an extension of the measuring distance or a shortening .
directiorl change for
"tapping cycle"
With parameter 67, a dwell time can be programmed such, that a change of rotating direction during spindle
retraction is prevented.

The adv,anced switchpoint refers to the reaching of the end position of the thread. With the aid of parameter 73,
retraction of the spindle can be compensated after the M 05 command.
Constant contouring
speed on external
corners
With parameter 91 an angle can be determined on corners on which the control can traverse at constant
speed. 2' should be considered as maximum: with greater angles, either the mechanical loading can be too
high or the drive demagnetised.

With machining cycles "pocket milling" and "circular pocket" the number of cuts required are calculated by
the cont.rol. The maximum pecking depth can be determined with machine parameter 93
The entered value is multiplied by the mill radius for the max. pecking depth in mm (not applicable
to variable contour pockets).
