2.11.4.2
Gear step change in active synchronous spindle coupling
Function
If a gear stage change is pending for the leading spindle of an active synchronous spindle
coupling, the a replacement subroutine can be called for the transmission of the gear stage
change. With the help of this replacement subroutine
•
the coupling is triggered
•
the gear stage change of the spindles involved in the coupling is executed
•
The coupling is closed again
Activation of the replacement for gear stage change
MD30465 $MA_AXIS_LANG_SUB_MASK, Bit 0 =1
The system variable
$P_SUB_AXFCT
delivers a bit mask that corresponds to machine data
MD30465 $MA_AXIS_LANG_SUB_MASK. A set bit provides information about the spindle-
related replacement that is currently active.
Call time of the replacement subroutine
While programming the gear stage change with M41 to M45, the output response of this
auxialiary function to the PLC depends on bits 5, 6, 7 of the machine data:
MD22080 $MC_AUXFU_PREDEF_SPEC[12] to
MD22080 $MC_AUXFU_PREDEF_SPEC[16]
References

Output of M41 to M45
Call of the replacement subroutine
before or during the movememt
At block start
after the movement
At block end
Note
The call always takes place at the block start during automatic gear stage change with M40.
Application
Machines with parallel processing of workpieces such as e.g., a double spindle machine
