2.11.4.3
Positioning spindle during active synchronous spindle coupling
Function
A replacement subroutine can be called if the leading spindle of an active synchronous
spindle coupling is to be positioned with SPOS, SPOSA or M19. With the help of this
replacement subroutine
•
the coupling is triggered
•
the spindles involved in the coupling are positioned separately at the
position specified by the leading spindle
•
The coupling is closed again
Activation of the replacement for gear stage change
MD30465 $MA_AXIS_LANG_SUB_MASK, Bit 1 =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
The call of the replacement subroutine during spindle positioning with SPOS or SPOSA
always takes place at the block start. The programming of M19 depends on the call time, on
Bit 5, 6, 7 of the machine data
MD22080 $MC_AUXFU_PREDEF_SPEC[9]
Configured output response to the PLC.

Call of the replacement subroutine
before or during the movememt
At block start
after the movement
At block end
Application
Parallel processing of workpieces e.g., in double-spindle machine. The spindles in such a
machine are coupled with the help of a coupling factor not equal to one and must e.g., be
positioned at the same position due to a tool change. If the coupling is separated earlier,
then each spindle can be positioned at the tool change position separately.
