Delete synchronism correction and NC reset

Variable $AA_COUP_CORR[Sn] returns the value zero for different situations in which the
synchronism correct is deleted:
● Once a synchronized spindle coupling has been activated for the following in question
● A synchronism correction active during NC reset but not at the parts program end is
● At M30, an existing synchronism correction is retained
● At the user end, the correction value can also be deleted at any early point by describing

Special points regarding start-up of a synchronous spindle coupling

Spindle start-up
The leading and following spindles must be started up initially like a normal spindle. The
corresponding method is described in

Requirements
The following parameters must then be set for the synchronous spindle pair:
● The machine numbers for the leading and following spindles
● required coupling mode (setpoint, actual value or speed coupling)
● select the gear stage(s) of FS and LS for synchronous operation
