Define/change coupling on user-specific basis
Activate coupling. The following spindle synchronizes to the leading spindle
based on the actual speed
Coupling when activating with previous programming of M3 S...
or M4 S....
A difference in speed for the following spindle is transferred immediately.
Deactivate coupling.
● with immediate block change:
COUPOF(<S2>,<S1>)
● Block change only after <POSFS> or <POSLS> deactivation position(s) has
(have) been crossed:
COUPOF(<S2>,<S1>,<POSFS>)
COUPOF(<S2>,<S1>,<POSFS>,<POSLS>)
Deactivating a coupling with stop of following spindle.
Block change as quickly as possible with immediate block change:
COUPOFS(<S2>,<S1>)
Block change only after passing the switch-off position:
COUPOFS(<S2>,<S1>,<POSFS>)
Reset coupling parameters to configured MD and SD
Delete user-defined coupling
Wait for synchronized run condition
(NOC are increased to IPO during block changes)
Designation of following spindle
Designation of main spindle
Specification with spindle number: e.g. S2, S1
Transformation ratio between FS and LS.
<ZFS>/<NLS> = numerator/denominator
Default setting: <ZFS> / <NLS> = 1.0 ; specification of denominator optional
