Axis couplings
11.5 Synchronous spindle
Note
The transformation ratio can also be changed on-the-fly (when the coupling is active and the
spindles are rotating).
Block change behavior NOC, FINE, COARSE, IPOSTOP
The following abbreviated notation can be used when programming the block change
behavior:

Type of coupling
Note
The coupling type may only be changed when the coupling is deactivated.
Activate synchronous mode COUPON, <POSFS>
● Activation of coupling with any angular offset between LS and FS:
● Activation of coupling with angular offset <
Note
The angular offset can also be changed when the coupling is active.
Position the following spindle
Even with activated synchronous spindle coupling, the FS can be positioned in the range
±180° independently of the LS.
● Spindle positioning of the FS with
