• a serial RS-232-C interface on the MMC module MMC100, and on
• the MMC modules MMC101 and MMC102 two RS-232-C interfaces
are available. Machining programs and manufacturer and user data can be loaded and
saved via these interfaces.
Services
Control operating area
Set
A section of a -> parts program terminated with a line feed. A distinction is made between ->
main blocks and -> subblocks.
Setting data
Data, which communicate properties of the machine tool to the NC control in a way defined
by the system software.
Simulator module
A simulator module is a module
• on which digital input variables can be simulated via control elements and
• digital output variables can be displayed.
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.
Software limit switch
Software limit switches limit the traversing range of an axis and prevent the slide from
striking the hardware limit switch. 2 pairs of values can be assigned on each axis, which can
then be activated separately via the -> PLC.
Spindle
The spindle functionality is divided into two power ranges.
1. Spindles: Speed- or position-controlled spindle drives, digital (SINUMERIK 840D)
2. Auxiliary spindles: speed-controlled spindle drives, "auxiliary spindle" function package,
e.g., for driven tools.
Spline interpolation
Using spline interpolation, the control can obtain a very smooth curve from just a few defined
interpolation points along a set contour.
