Replacement of spindle functions

9.15.3.1

General

Function
When a coupling is active the following spindle functions can be replaced for leading spindles:
• M40: Automatic gear stage change
• M41 ... M45 Programmed gear stage change
• SPOS, SPOSA and M19: Spindle positioning
Boundary conditions
• To replace a spindle function, the following conditions must be met:
- The programmed spindle must be the leading spindle of an active coupling.
- Leading and following spindle are located in the same channel. This is only detected if the leading spindle
is located in the channel in which the coupling was closed. If the leading spindle is changed to another
channel, a gear stage change or positioning of this spindle does not call the replacement subprogram.
- A programmed gear stage change must result in a real gear stage change. For this purpose, the
programmed and active gear stage must differ.
• In a block, only one spindle function can be replaced. Multiple replacements lead to the termination of the
program processing. The spindle functions, which are to be replaced, must then be distributed over several
blocks.
