Rotation
Component of a -> frame which defines a rotation of the coordinate
system through a specific angle.
Rounding axis
Rounding axes cause the workpiece or tool to rotate to an angle
position described on a graduated grid. When the grid position has
been reached, the axis is "in position".
S
S7 Configuration
S7 Configuration is a tool for parameterizing modules. S7
Configuration is used to set a variety of
-> parameter blocks of the -> CPU and the I/O modules on the
-> programming device. These parameters are uploaded to the CPU.
S7-300 bus
The S7-300 bus is a serial data bus which supplies modules with the
appropriate voltage and via which they exchange data with one
another. The connection between the modules is made by means of
-> bus connectors.
Safety functions
The control includes continuously active monitoring functions which
detect faults in the -> CNC, the programmable controller (-> PLC) and
the machine so early that damage to the workpiece, tool or machine
rarely occurs. In the event of a fault, the machining operation is
interrupted and the drives stopped. The cause of the malfunction is
logged and an alarm issued. At the same time, the PLC is notified that
a CNC alarm is pending.
Scaling
Component of a -> frame which causes axis-specific scale alterations.
Serial RS-232 interface
For data input / output, one serial RS-232 interface is available on the
MMC module MMC100, and two serial RS-232 interfaces on the MMC
modules MMC101 and MMC102. Machining programs and
manufacturer and user data can be imported and exported via these
interfaces.
Services
Control operating area
Setting data
Data which provide the control with information about properties of the
machine tool in a way defined by the system software.
Simulator module
A simulator module is a module,
· on which, via control elements, digital input values can be
simulated and
· digital output values are displayed.
