Predefined functions

Predefined functions
Predefined functions are invoked by means of a function call. Function calls return a value.
They can be included as an operand in an expression.

Explanation
Translation: Zero offset
for multiple axes.
One axis identifier is
programmed at a time,
with its respective value
in the next parameter.
CTRANS can be used to
program offset for up to
8 axes.
Rotation: Rotation of the
current coordinate
system.
Maximum number of
parameters: 6 (one axis
identifier and one value
per geometry axis)
Scale: Scale factor for
multiple axes.
Maximum number of
parameters is 2*
maximum number of
axes (axis identifier and
value per axis).
One axis identifier is
programmed at a time,
with its respective value
in the next parameter.
CSCALE can be used to
program scale factors
for up to 8 axes.
Mirror: Mirror on a
coordinate axis
Frame calculation from 3
measuring points in
space
