if there is anybody with exp with CSMIO/IP-A Ethernet Motion Controller (+/- 10V) 6 axis and or machmotion interpreter 1000 controller both of which are what I would like or very close!!! im just looking for any down sides. These will control siemens simodrive 611 rack with spindle as the main concern???? just wondering if the spindle can still be addressed as s 500 m3 when using one of the (6) +-10 volt signals??? xyz being three of them and spindle and C&B axis being the others> I do realize that the thread first started off on a vmc760 note... so I could really still use and ideas on the spindle not up to speed issues and wondering if there anybody with any numbers for all there peramiters for s axis feedback servo and differential gain encoder counts and resolution etc... and or guidance as to which section of the 900 page pdf for simodrive on tuning spindle???
