Detailed description2.1 Speed/torque coupling, master-slave (SW 6 and higher)Special functions: Speed/Torque Coupling, Master-Slave (TE3)14 Function Manual, 11/2006, 6FC5397-2BP10-2BA0Control system responseThe control system response on POWER ON, mode changes, RESET, block searches andRepos is as follows:• A master-slave coupling activated via PLC or MASLON instruction is retained after a modechange, RESET or end of part program.• MASLON / MASLOF/ MASLOFS becomes effective on block search. Changes in thepositions of coupled slave axes and spindle speeds must be computed separately by theuser (see "Block search", Chapter "Response in conjunction with other functions").2.1.7 Response on activation/deactivationActivating/deactivating during axis standstillActivation/deactivation is not active until the axis next comes to a standstill. If thespecification is changed, the sequence is the same as for axis replacement. The coupling isclosed when the axis comes to a standstill. The coupled axes must be in feedback controlmode.$[LVVSLQGOHVWDWLRQDU\'%'%;0DVWHUVODYHDFWLYH'%'%;0$6/210$6/2)0DVWHU6ODYH21'%'%;Figure 2-7 Activation procedureBlock stepping is halted for MASLON until the coupling has actually been closed. During thistime, the associated channel operating message "Master-slave switchover inactive" isdisplayed on the MMC/HMI.Activation/deactivation during motion, SW 6.4 and higherActivation/deactivation of the coupling in motion has been implemented only for spindles inspeed control mode. For axes and spindles in positioning mode, switchover is still carried outwhen the axis is at a standstill.
