SINUMERIK 840D/840Di/810D Operator's Guide HMI Advanced (BAD) – 03.04 Edition
Logical unit of the -> NCK which determines intermediate values for
the movements to be traversed on the individual axes on the basis of
destination positions specified in the parts program.
Interrupt routines are special -> subroutines which can be started by
events (external signals) in the machining process. The parts program
block being processed is aborted and the axis position at the instant
of interruption is stored automatically.
On SINUMERIK FM-NC and 840D controls, it is possible to program
the time required to traverse the path of a block instead of the
feedrate speed for the axis movement (G93).
Control system operating mode (setup): The machine can be set up in
Jog mode. Individual axes and spindles can be jogged by means of
direction keys. Other functions in Jog mode are -> reference point
approach, -> Repos and -> Preset -> (set actual value).
1. S7-300: The keyswitch is the mode selector switch on the
-> CPU. The keyswitch is operated by means of a removable key.
2. 840D/FM-NC: The keyswitch on the -> machine control panel has
4 positions which are assigned functions by the operating system
of the control. There are also three keys of different colors
belonging to the keyswitch that can be removed in the specified
positions.
Transmission Ratio
Servo gain factor, control variable of a control loop
The user interface texts, system messages and alarms are available
in five system languages (floppy disk):
English, French, German, Italian and Spanish.
The user can select two of the listed languages at a time in the
control.
Compensation of mechanical inaccuracies in a leadscrew involved in
the feed motion. Errors are compensated by the control based on
stored deviation measurements.
