Glossary
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.
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 → Programmable logic control.
Cycles
Protected subroutines for implementing a repetitive machining operation on the → workpiece.
Data Block
Data unit of the → NC: Data modules contain data definitions for global user data. These
data can be initialized directly when they are defined.
Data word
Two-byte data unit within a → data block.
