Glossary
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
See → Machine coordinate system, → Workpiece coordinate system
CPU
Central processing unit, see → PLC
