The CNC programming language is based on DIN 66025 with
high--level language expansions. The --> CNC programming
language and --> high--level language expansions support the
definition of macros (sequenced statements).
Numerical control component for the implementation and
coordination of communication.
Command axes are started from synchronized actions in response
to an event (command). They can be positioned, started and
stopped fully asynchronous to the part program.
Axis having a setpoint or actual value modified by the compensation
value.
Table of interpolation points. It supplies the compensation values of
the compensation axis for selected positions of the base axis.
Difference between the axis position measured by the position
sensor and the desired, programmed axis position.
Connecting cables are pre--assembled or user--assembled 2--wire
cables with a connector at each end. They are used to connect the
--> CPU via the --> multipoint interface (MPI) to a --> programming
device or to other CPUs.
The purpose of continuous--path control mode is to prevent
excessive deceleration of the --> path axes at the part program
block limits that could endanger the operator or the control, machine
or other assets of the plant and to effect the transition to the next
block at as uniform a path speed as possible.
Outline of a --> workpiece.
The following error is monitored within a definable tolerance band as
a measure of contour accuracy. Overloading of the drive, for
example, may result in an unacceptably large following error. In
such cases, an alarm is output and the axes stopped.
