Behavior during presetting

Presetting in a rotary axis has

the same effect as an axis offset.

The offset is also effective for

kinematics calculations and for

tilting the working plane.
The machine parameter

CfgAxisPropKinn-

>presetToAlignAxis is used to

define whether the axis offset is

to be taken into account internally

after zero setting.
Independently of this, an axis

offset has always the following

effects:

An axis offset always

influences the nominal position

display of the affected axis (the

axis offset is subtracted from

the current axis value).
If a rotary axis coordinate is

programmed in an L block, then

the axis offset is added to the

programmed coordinate.

Rotary axis offsets defined by

machine parameters do not

influence the axis positions that

were defined in the Tilt working

plane function.
MP7500 bit 3 defines whether

the current rotary axis position

referenced to the machine datum

is taken into account, or whether

a position of 0° is assumed for

the first rotary axis (usually the C

axis).

Definition of feed-rate limitation

Feed-rate limitation can be

defined separately for linear and

rotary axes

Only one feed-rate limitation can

be defined for linear and rotary

axes
