Basic Functions
1308 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
• 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.
16.4.7 Gear step change with oscillation mode
What is oscillation?
Oscillation in this context means that the spindle motor rotates alternately in the clockwise and counterclockwise
directions. This oscillation movement makes it easy to engage a new gear step.
Oscillation mode
NC/PLC IS:
DB31, ... DBX82.3 (Change gear)
displays that a gear step change is required.
In principle, the new gear step can also be engaged without oscillation
1. MD35010 $MA_GEAR_STEP_CHANGE_ENABLE must be set to 1.
2. NC/PLC interface signals DB31, ... DBX84.6 (oscillation mode) is set.
3. The acceleration is set in the machine data:
MD35410 $MA_SPIND_OSCILL_ACCEL
