Hi All, I do understand the idea of : - each axis as a ref sensor - 1st axis does homing alone, then 2nd one - then gearing, and here we go ... ... But what if : both axis are linked together via a solid mechanical part ? What we would like to do is : 1/ - each axis NOT geared : move manually each one so that they become aligned 2/ - install the solid mechanial part that link both axis 3/ - push a button on HMI to validate the gearing (mechanical and electrical) 4/ - master axis is enabled to do a homing (searching reference sensor), and slave follows it , and receives the same "zero" so that it don't try to reach suddenly the "zero" when master receives it, or goes in "following error" trying to do it 5/ - of course for maintenance purpose, it is always possible to break gearing , in order to set ... unmount the mechanical part... etc ; then go back to 1/ Thx ------------------------------------------------------------------------------------------ |

Hello, when the coupling is "gantry" you have to use Gearing and in this case absolute encoder are recommended, because thre is no need of a homing procedure after power on. When there isa stiff coupling (tooth wheel or same shaft or ,,, ) you need load sharing. https://support.industry.siemens.com/cs/ww/en/view/109774232 https://support.industry.siemens.com/cs/ww/en/view/38470057 |

Hello, there are application example only for V16. V90 Load sharing for two SINAMICS V90PNs https://support.industry.siemens.com/cs/ww/en/view/109794290 You can use the following example for S210, or for all other drives using technology objects.
