Detailed description2.1 Speed/torque coupling, master-slave (SW 6 and higher)Special functions: Speed/Torque Coupling, Master-Slave (TE3)20 Function Manual, 11/2006, 6FC5397-2BP10-2BA0Weight counterbalanceThe additional torque for the electronic weight counterbalanceMD32460 $MA_TORQUE_OFFSETis computed in the slave axis irrespective of the coupling status.Gear stage change with active master-slave couplingAn automatic gear stage change in a coupled slave spindle is not possible and can only beimplemented indirectly using the master spindle. The point in time at which the gear stage ischanged is then derived from the master spindle. The oscillating motion of the coupled slavespindle is generated implicitly via the oscillating motion of the master spindle.in contrast to the master spindle, the associated parameter block must be explicitly selectedin the coupled slave spindle. To enable the parameter block to be specified, the followingmachine data must be set to the value 2:MD35590 $MA_PARAMET_CHANGE_ENABLEIn the event of a gear stage change for the master/slave spindle, the associated parameterset index can be activated by the PLC via the VDI interface.NoteFor more information about gear stage change and parameter sets for changes in spindlemode, see:References:/FB1/ Description of Functions, Basic Functions; Spindles (S1)/FB1/Function Manual Basic Functions; Various Interface Signals (A2)Interface signals from/to axis/spindleAxis containerIf a coupled slave axis is configured in an axis container, alarm "4025 Switch axis container%3 not permitted: Master-slave active channel %1 Axis %2" is output. The axis containermay not be advanced because the coupling is active.SW 6.4 and higherIn the event that masters change, dynamic configuration can be used to match the relevantspindle the master spindle following a rotation of the axis container. Both master and slavespindles can be container spindles.For a coupling to be closed after container rotation using a different spindle in each case, theold coupling must be disconnected before the rotation, the configuration deleted and the newcoupling closed after the rotation.
