2.3.3 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
Compensation block alarms
Overstore
Rapid retraction with G33, G34, G35
Subroutine level abort, subroutine abort
Response after POWER ON
The active gear step on the machine can be specified by the PLC control after POWER ON
and in the RESET state.
The NCK will then select the appropriate parameter set
and check back the NC/PLC interface signals:
DB31, ... DBX82.0-82.2 (Set gear step A to C)
to the PLC.
