In 840d controller We have ball screw arrangement in X axis & pitch of this screw is 16 mm ( MD 31030- 16mm/rev ), Now we want to replace this ball screw with 10mm pitch. If it’s possible please explain.Awaiting your early response. Thanking you.

If it’s possible please explain.Awaiting your early response. Thanking you.  Replace is posible. Perhaps: You must additionary reduct you speed.  !    (Please check it) As example   maxinal speed  16m/min   with ball screw 16mm. maxinal speed  10m/min   with ball screw 10mm. (The Motor and mechanic  must be faster if you want the old speed, possible) Do you have a measuring System on this axis  ? If yes, you must additionl change other parameters. Greatings Karl   Karl

Which is the additional parameter wants to be modify
