Detailed Description
2.3 Configurable gear adaptation
Spindles (S1)
2-38 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Block change
When programming the gear step change in the part program, the gear step change set
remains active until the gear step change is aborted by PLC. (Same effect, as if NC/PLC IS:
DB21, ... DBX6.1 (Read-in enable) is set.)
Specification of gear step via PLC with FC18
The gear step change can also be performed by function block FC18 during a part program,
in the reset state or in all operating modes.
If the speed and direction of rotation is specified with FC18, the NC can be requested to
select the gear step as appropriate for the speed. This corresponds to an automatic gear
step change with M40.
The gear step is not changed if the spindle is positioned by FC18 or if traversing in axis
mode.
For more information about function block FC18, please refer to:

Specification of gear step with synchronized actions
The gear step change can be requested by synchronized actions:
• In the event of automatic gear step change for M40 with S
or
• When specifying gear steps 1 to 5 with M41 to M45.
The gear step is not changed if the spindle is positioned by synchronized actions or if
traversing in axis mode.
Manual specification of a gear step
Outside a part program that is running, the gear step can also be changed without a request
from the NC or the machine. This is the case, for example, when a gear step is changed
directly by hand.
To select the appropriate parameter sets, the NC must be informed of the current gear step.
For this to work, the control or the part program must be in the reset state.
Supplementary conditions
Transfer of the gear step to the NC is initiated when
NC/PLC IS:
DB31, ... DBX16.0-16.2 (actual gear step 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 step A to C)
to the PLC.
