Glossary
Scaling
Component of a → frame that implements axis-specific scale modifications.
Serial RS-232-C interface
A serial RS-232-C interface is available on the PCU for the data input/output. Machining
programs and manufacturer and user data can be loaded and saved via this interface.
Setting data
Data which communicates the properties of the machine tool to the NC, as defined by the
system software.
Softkey
A key whose name appears on an area of the screen. The choice of softkeys displayed is
dynamically adapted to the operating situation. The freely assignable function keys
(softkeys) are assigned defined functions in the software.
Software limit switch
Software limit switches limit the traversing range of an axis and prevent an abrupt stop of the
slide at the hardware limit switch. Two value pairs can be specified for each axis and
activated separately by means of the → PLC.
Spline interpolation
With spline interpolation, the control can generate a smooth curve characteristic from only a
few specified interpolation points of a set contour.
SRT
Gear ratio
Standard cycles
Standard cycles are provided for machining operations which are frequently repeated:
● Cycles for drilling/milling applications
● For turning technology
● For grinding technology
The available cycles are listed in the <Technology> menu in the "Program" operating area.
Once the desired machining cycle has been selected, the parameters required for assigning
values are displayed in plain text.
