Spindle behavior at the end of gear step change
End of gear step change
• NC/PLC IS:
DB31, ... DBX16.3 (Gear changed)
tells the NC that the new gear step
(NC/PLC IS DB31, ... DBX16.0-16.2 (Actual gear step A to C))
applies 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 should correspond to the set gear step.
The actual gear step signaled is relevant for selection of the parameter set.
• Once the gear step change (GSW) has been acknowledged via the PLC (DB31, ...
DBX16.3), the spindle is in speed control mode (DB31, ... DBX84.7 = 1).
If a direction of rotation (M3, M4, M5 or FC18: "Start spindle rotation") or a spindle speed
(S value) was programmed before the gear step change, then the last speed and
direction of rotation will be reactivated after the gear step change.
2.1.3 Spindle oscillation mode
Operating principle
Oscillation mode is activated for the spindle during the gear step change.
