COM
Component of the NC control for the implementation and coordination of communication.
Compensation axis
Axis with a setpoint or actual value modified by the compensation value
Compensation memory
Data range in the control, in which the tool offset data are stored.
Compensation table
Table containing interpolation points. It provides the compensation values of the
compensation axis for selected positions on the basic axis.
Compensation value
Difference between the axis position measured by the encoder and the desired, programmed
axis position.
Connecting cables
Connecting cables are pre-assembled or user-assembled 2-wire cables with a connector at
each end. This connecting cable connects the → CPU to a → programming device or to other
CPUs by means of a → multi-point interface (MPI).
Continuous-path mode
The objective of continuous-path mode is to avoid substantial deceleration of the → path
axes at the part program block boundaries and to change to the next block at as close to the
same path velocity as possible.
Contour
Contour of the → workpiece
Contour monitoring
The following error is monitored within a definable tolerance band as a measure of contour
accuracy. An unacceptably high following error can cause the drive to become overloaded,
for example. In such cases, an alarm is output and the axes are stopped.
Coordinate system
