Table of Contents

Computerized Numerical Control: includes the components → NCK, → PLC, HMI, → COM.

Component of the NC for the implementation and coordination of communication.

Compensation axis

Axis with a setpoint or actual value modified by the compensation value

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 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

Central processing unit, see → PLC
