Designation of main spindle;
Specification with spindle number: e.g. S2, S1
, T Speed ratio parameters for FS = numerator and LS = denominator
LS
Default setting = 1.0; specification of denominator optional
Block change method; Block change is implemented:
Immediately
At "Synchronism fine"
At "Synchronism coarse"
in response to IPOSTOP (e.g. after setpoint-based synchronism)
(presetting)
The block change method is modal
Coupling type: Coupling between FS and LS
Setpoint linkage (default)
Actual value coupling
Speed coupling
The coupling type is modal.
Angle offset between leading and following spindles
FS
, POS Switch-off positions of following and main spindles

"The block change is enabled once POS
crossed"

;Leading spindle = master spindle =
;spindle 1
;Following spindle = spindle 2
;Master spindle rotates at 3000 rpm
;following spindle at 500 rpm
;Def. of coupling, can also be configured
;Include master spindle in position control
;(setpoint coup.)
;Include slave spindle in position control
;On-the-fly coupling to offset position =
