Rotation
Component of a → frame that defines a rotation of the coordinate system around a particular
angle.
Rounding axis
Rounding axes rotate a workpiece or tool to an angular position corresponding to an
indexing grid. When a grid index is reached, the rounding axis is "in position".
RS-232-C
Serial interface for data input/output. Machining programs as well as manufacturer and user
data can be loaded and saved via this interface.
Safety functions
The controller is equipped with permanently active monitoring functions that detect faults in
the → CNC, the → PLC, and the machine in a timely manner so that damage to the
workpiece, tool, or machine is largely prevented. In the event of a fault, the machining
operation is interrupted and the drives stopped. The cause of the malfunction is logged and
output as an alarm. At the same time, the PLC is notified that a CNC alarm has been
triggered.
Scaling
Component of a → frame that implements axis-specific scale modifications.
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.
