Basic FunctionsFunction Manual 09/2011, 6FC5397-0BP40-2BA0 1753GlossaryAbsolute dimensionsA destination for an axis movement is defined by a dimension that refers to the origin of the currently activecoordinate system. See → Incremental dimensionAcceleration with jerk limitationIn order to optimize the acceleration response of the machine whilst simultaneously protecting the mechanicalcomponents, it is possible to switch over in the machining program between abrupt acceleration and continuous(jerk-free) acceleration.AddressAn address is the identifier for a certain operand or operand range, e.g. input, output etc.AlarmsAll → messages and alarms are displayed on the operator panel in plain text with date and time and thecorresponding 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 PLCAlarms and messages for the machine can be displayed in plain text from the PLC program. No additionalfunction block packages are required for this purpose.ArchiveReading out of files and/or directories on an external memory device.Asynchronous subroutinePart program that can be started asynchronously to (independently of) the current program status using aninterrupt signal (e.g. "Rapid NC input" signal).AutomaticOperating mode of the control (block sequence operation according to DIN): Operating mode for NC systems inwhich a → subprogram is selected and executed continuously.
