Hi Guys,

I'm currently in the process of swapping my 380v 6.5kw 400Hz spindle over to an ATC version which is 380v 5.5kw 800Hz.

I'm running a Rexroth 5610 VFD and setup everything to suit the new 800Hz Spindle....or so I thought.

At this point I'm not sure why the VFD never took the settings and it ran up at 400Hz. It took me 10 mins of it running before I noticed the temp sensor inside the spindle was reading 30 degrees c. I was watching the water temp which was only 15 degrees Cand thought all was well. I should of new better but it was a long day.I switched it off right away when I clocked the internal temp reading.

Will this of damaged my new spindle guys? I need to go back tomorrow to find out why the VFD never saved down the new settings correctly.

Thanks
Paul
