Operating modes, program operation (K1)

10.1

Brief description

Program operation
The execution of part programs or part program blocks in "AUTO" or "MDA" mode is referred to as program operation.
During execution, the program sequence can be controlled by PLC interface signals and commands.
Channel
A channel constitutes a unit in which a part program can be executed.
A channel is assigned an interpolator with program processing by the system. A certain mode is valid for it.
The SINUMERIK 808D/SINUMERIK 808D ADVANCED control system has one channel.

Operating modes

10.2.1 Operating modes
Activating
The required operating mode is activated by the interface signals in the DB3000.DBB0000. If several modes are selected at
the same time the priority of the operating modes is as follows:
● JOG (high priority): The axes can be traversed manually with the handwheel or the traversing keys. Channel-specific
signals and interlocks are not observed.
● MDA: Program blocks can be processed
● AUTO (lower priority): Automatic processing of part programs
Feedback signal
The active operating mode is displayed by the interface signals in the DB3100.DBB0000.
Possible machine functions in JOG
The following machine function can be selected in "JOG" operating mode:
REF (reference point approach)
The required machine function is activated with IS "REF" (DB3000.DBX0001.2). The display is visible in the IS "active
machine function REF" (DB3100.DBX0001.2).
Stop
A stop signal can be issued with the following interface signals
● IS "NC stop" (DB3200.DBX0007.3)
● IS "NC stop axes plus spindles" (DB3200.DBX0007.4)
● IS "NC stop at block limit" (DB3200.DBX0007.2)
Depending on the interface signal used, either only the axes or in addition the spindles of the channels are stopped or the
axes at block end.
RESET
The active part program is aborted by the IS "Reset" (DB3000.DBX0000.7).
The following actions are executed when the IS "Reset" is triggered:
● Part program preparation is stopped immediately.
● Axes and spindles are stopped.
● Any auxiliary functions of the current block not yet output, are no longer output.
