Compensation memory
Data storage area in the control system, in which the tool offset data are stored.
Compensation table
Table of interpolation points. It delivers the offset values of the offset axis for the selected
positions of the basic axis.
Connecting cables
Connecting cables are either pre-assembled cables or cables that are pre-assembled, ready-
to-use two-wire cables that have a connector at both ends. Connecting cables are used to
connect the -> CPU to a -> programming device or another CPU with use of a -> multipoint
interface (MPI).
Continuous-path mode
The purpose of the continuous path mode is to avoid an excessive acceleration of the ->
path axes at the block limits of part programs, which may affect the operator, the machine or
other assets of the plant. The continuous-path mode is expected to influence the transition to
the next block in the NC program and to maintain the path velocity as uniformly as possible.
Contour
Contours of a workpiece.
Contour monitoring
The following error is monitored as a measure for contour precision within a defined
tolerance range. Thus, for instance, an overloading of the drive can lead to a sequential fault,
which is no longer acceptable. An alarm is output and the axes are stopped in this case.
Correction value
The distance between the axis position and the desired programmed axis position measured
with a position encoder.
CPU
Central Processor Unit -> programmable logic control system
Cycle
Protected subprogram for executing machining operations, which are always repeated at the
-> workpiece.
