Rotary axis
Rotary axes rotate a workpiece or tool to a defined angular position.
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".
Safety functions
The control is equipped with permanently active montoring 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 malfunction, the machining sequence
is interrupted and the drives are stopped and the cause of the malfunction is saved and
displayed as an alarm. At the same time, the PLC is informed that a CNC alarm is pending.
Scaling
Component of a → frame that implements axis-specific scale modifications.
Serial V.24 interface
For data input/output, the PCU 20 has one serial V.24 interface (RS232) while the
PCU 50/70 has two V.24 interfaces. Machining programs and manufacturer and user data
can be loaded and saved via these interfaces.
Services
Control operating area
Setting data
Data that communicate properties of the machine tool to the NC control in a manner defined
by the system software.
Softkey
A key whose name appears on an area of the screen. The selection of keys displayed is
adapted dynamically to the operating situation. The freely assignable function keys
(softkeys) are assigned defined functions in the software.
