Functionality
Machine tools of conventional design require a gear step change of the spindle in oscillation mode.
If the machine data configuration is:
MD35010 $MA_GEAR_STEP_CHANGE_ENABLE = 1
the following sequence is implemented:
• Deceleration of the spindle.
The braking action corresponds to an M5 movement.
• Output of VDI interface signals:
DB31, ... DBX84.6 (Oscillation mode)
DB31, ... DBX82.3 (Change gear)
DB31, ... DBX82.0-82.2 (Set gear step A to C).
If position control has been enabled, it is disabled:
DB31, ... DBX61.5 = 0.
• The load gearbox can now "disengage".
• NC/PLC IS:
DB31, ... DBX18.5 (Oscillation enable)
can be set by the PLC.
The spindle motor then performs an oscillation motion with preset values.
The oscillation motion is designed to facilitate and accelerate the re­engaging of the gear wheels.
• Writing of NC/PLC IS:
DB31, ... DBX16.0-16.2 (Actual gear step A to C)
by the PLC.
• Once the PLC has sent:
DB31, ... DBX16.3 (Gear changed)
to the NCK, the last movement to be active is continued, if available.
For indirect encoders (motor encoders), the homing status is cleared:
DB31, ... DBX60.4/5 = 0.
Block change
If the spindle is switched to oscillation mode
with NC/PLC IS:
DB31, ... DBX82.3 (Change gear)
, the processing of the part program remains suspended.
A new block is not executed.
If oscillation mode is terminated with NC/PLC IS:
DB31, ... DBX16.3 (Gear changed)
, the processing of the part program is resumed.
A new block is executed.
