Mode Types And Mode Type Change - Siemens SINUMERIK 840D sl Function Manual

Effect
Effect on the channels of mode group:
● Part program preparation (preprocessing) is stopped.
● All axes and spindles are decelerated to zero speed according to their acceleration curves
without contour violation.
● Any auxiliary functions not yet output to the PLC are no longer output.
● The preprocessing pointers are set to the interruption point, and the block pointers are set
to the beginning of the appropriate part programs.
● All initial settings (e.g. the G functions) are set to the parameterized values.
● All alarms with "Channel reset" criterion are canceled.
If all the channels of the mode group are in reset state, then:
● All alarms with "Mode group reset" cancel criterion are canceled.
● The NC/PLC interface indicates completion of the mode group Reset and the mode group's
readiness to operate:
DB11 DBX6.7 (all channels in the reset state)
DB11 DBX6.3 = 1 (mode group ready)

Mode types and mode type change

Unique mode
All channels of a mode group are always in the same mode:
● AUTOMATIC
● JOG
● MDI
If individual channels are assigned to different mode groups, a channel switchover activates
the corresponding mode group. This allows mode changes to be initiated via a channel
switchover.
Modes
The following modes are available:
● AUTOMATIC
Automatic execution of part programs:
– Part program test.
– All channels of the mode group can be active at the same time.
● JOG in Automatic
JOG in AUTOMATIC is an extension of AUTOMATIC mode intended to simplify use. JOG
can be executed without leaving AUTOMATIC mode if boundary conditions so permit.
