Glossary

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.
Address
An address is the identifier for a certain operand or operand range, e.g. input, output etc.
Alarms
All → messages and alarms are displayed on the operator panel in plain text with date and time and the
corresponding symbol for the cancel criterion. Alarms and messages are displayed separately.
1. Alarms and messages in the part program:
Alarms and messages can be displayed in plain text directly from the part program.
2. Alarms and messages from PLC
Alarms and messages for the machine can be displayed in plain text from the PLC program. No additional
function block packages are required for this purpose.
Archive
Reading out of files and/or directories on an external memory device.
Asynchronous subroutine
Part program that can be started asynchronously to (independently of) the current program status using an
interrupt signal (e.g. "Rapid NC input" signal).
Automatic
Operating mode of the control (block sequence operation according to DIN): Operating mode for NC systems in
which a → subprogram is selected and executed continuously.
