Manual specification of a gear stage
Outside a part program that is running, the gear stage can also be changed without a request from the NC or the
machine. This is the case, for example, when a gear stage is changed directly by hand.
To select the appropriate parameter set, the NC must be informed of the current gear stage. For this to work, the
control or the part program must be in the reset state.
Boundary conditions
Transfer of the gear stage to the NC is initiated when
NC/PLC IS:
DB31, ... DBX16.0-16.2 (Actual gear stage A to C) changes.
These three bits must be set continuously during operation.
Successful transfer is acknowledged with NC/PLC IS:
DB31, ... DBX82.0-82.2 (Set gear stage A to C)
to the PLC.
NC/PLC IS:
DB31, ... DBX16.3 (Gear changed)
must not be set.
If position control is active when a new gear stage is specified by PLC with DB31,...DBX16.0-16.2, then it is
switched off for the duration of this changeover sequence.
Note
For further details, please refer to the section "Specification of a gear stage in part
program".
Exception:
The block change is not affected by the specification of a gear stage in synchronized
actions.
