Absolute dimensions
A destination for an axis movement is defined by a dimension that refers to the origin of the
currently active coordinate system. See -> incremental dimension.
Acceleration with jerk limitation
In order to optimize the acceleration response of the machine whilst simultaneously
protecting the mechanical components, it is possible to switch over in the machining program
between abrupt acceleration and continuous (jerk-free) acceleration.
Access authorization
The CNC program blocks and data are protected via a 7-stage access authorization
procedure.
• three password levels for system manufacturers, machine manufacturers and users, plus
• four keyswitch positions, which can be evaluated via the PLC.
Address
An address is the identifier for a certain operand or operand range, e.g., input, output, etc.
Analog input/output module
Analog input/output modules are signal formers for analog process signals.
Analog input modules convert analog measured values into digital values, which can be
processed in the CPU.
Analog output modules convert digital values into analog output signals.
Approach machine fixed-point
Approach motion towards one of the predefined -> fixed machine points.
Archiving
Reading out files and/or directories to an external memory device.
