Hi jazz
Thanks a lot for your reply, The motors are running in opposite direction right from the control board, s therefore I do not need to slave it anymore. But on the issue of second switch, sounds interesting please explain, particularly on Index pulse, how this can be done?
Also another challenge is placing the switch itself, which must be in exact position of the other one.
regards

Think you misunderstand what slaving is about. It's nothing to do with running motors in opposite directions. It's about two separate Motor outputs working as one unit. The way you have it wired you are using just one output which is sharing it's pulses between two drives. This can lead to timing issues between those drives because cannot gaurantee they will both see pulse exactly at same time. Pulse timing is critical.
Also like mentioned it also affects homing because only using one switch.
Regards using the Index pulse then this depends on your Drives and if they have Index pulse output and allow Home to index feature. Most servo drives do, in this case you can tell the drives to home to index by using one of it's inputs then when at home position it turns on it's Index output which then tells controller at home location.
