Sequence for switchover
If the new gear step is preselected, the following sequence is implemented:
NC/PLC interface signals:
DB31, ... DBX82.0-82.2 (Set gear step A to C)
and
DB31, ... DBX82.3 (Change gear)
are set.
In accordance with the point at which NC/PLC IS:
DB31, ... DBX18.5 (Oscillation speed)
is set, the spindle decelerates to a standstill at the acceleration for oscillation or at the
acceleration for speed control/position control.
Oscillation can be activated at the latest when the spindle reaches a standstill
(NC/PLC IS: DB31, ... DBX61.4 (Axis/Spindle stationary)
with NC/PLC IS:
DB31, ... DBX18.5
(Oscillation speed).
In principle, the new gear step can also be engaged without oscillation
When the new gear step is engaged,
the NC/PLC interface signals DB31, ... DBX16.0-16.2 (actual gear step A to C)
and
DB31, ... DBX16.3 (Gear changed)
are set
by the PLC program.
End of gear step change
The gear step change is considered completed ("oscillation" spindle mode is deselected)
and the spindle is switched to the servo and interpolation parameter set of the new actual
gear step.
NC/PLC IS:
DB31, ... DBX82.3 (Change gear)
is reset by the NCK,
which causes the PLC program to reset NC/PLC IS:
DB31, ... DBX16.3 (Gear changed).
NC/PLC IS:
DB31, ... DBX16.3 (Gear changed)
tells the NC that the new gear step applies with NC/PLC IS:
DB31, ... DBX16.0-16.2 (Actual gear step A to C)
and oscillation mode is terminated.
In this case, it does not matter whether NC/PLC IS:
DB31, ... DBX18.5 (oscillation mode)
is still set.
The actual gear step, which should correspond to the set gear step, is relevant
for selecting the parameter set.
If this is not the case, machine data setting:
MD11410 $MN_SUPPRESS_ALARM_MASK, Bit 3 = 0
triggers alarm 22010.
