Note
For the slave axis, the actual value can be synchronized to the same value of the master
axis with PRESETON. For this purpose, permanent master/slave coupling must be
deactivated briefly to set the actual value of the unreferenced slave axis to the value of the
master axis with Power On. After that, the permanent coupling is restored.
The permanent master/slave coupling is activated with MD 37262:
MS_COUPLING_ALWAYS_ACTIVE = 1 and does not have any affect on the commands of
the temporary coupling.
Coupling characteristics for spindles, SW 6.5 and higher
For spindles in the speed control mode, the coupling characteristics for MASLON, MASLOF,
MASLOFS and MASLDEL are explicitly specified using the MD 37263:
MS_SPIND_COUPLING_MODE.
In the default setting with MD 37263 = 0, the coupling and separation of the slave axes are
performed only when the associated axes are stopped. MASLOFS corresponds to the
MASLOF.
For MD 37263 = 1, the coupling statement is performed immediately, and thus also in the
motion. The coupling will be closed immediately for MASLON and immediately separated for
MASLOFS or MASLOF . The slave spindles turning at this time will be automatically
decelerated for MASLOFS and for MASLOF retain their speed until a new speed
programming is made.
