Switchover
Switchover to a new transmission ratio is performed immediately by means of NewConfig. From a technological
viewpoint, the associated mechanical switchover process takes some time, since, in mechanical terms, a
different intermediate gear with rotating tool is being installed.

16.4.6 Nonacknowledged gear step change
Mode change
A gear step change that has not been acknowledged cannot be interrupted by a change in operating mode (e.g.,
switchover to JOG).
The switchover is delayed by the maximum period entered in machine data:
MD10192 $MN_GEAR_CHANGE_WAIT_TIME
.
If the gear step change is not acknowledged within this time, the NC will output an alarm:
Further events
Events that initiate reorganization will also wait until a gear step change is completed.
The time entered in machine data:
MD10192 $MN_GEAR_CHANGE_WAIT_TIME
determines how long the control waits before executing the gear step change.
If this time elapses without the gear step change being completed, the NC responds with an alarm.
The following events have an analog response:
• User ASUB
• Mode change
• Delete distance-to-go
• Axis replacement
• Activate PI user data
• Enable PI service machine data
• Switch over skip block, switch over Dry Run
• Editing in the modes
Note
At zero speed, switchover is jerk-free. The user is therefore responsible for taking
appropriate precautions.
Applications in which switchover takes place during motion and which require smoothed or
soft speed transition can be handled using existing setpoint speed filters.
