According to the spec sheet I posted, wired as the middle variance, they are 8.96v if that is what you are referring to. Thanks

P is set wrong in the ini file. Its set for 10000 which will result in oscillations.
It should be set to 1/servo period or 1000 for a 1 ms (1000000 ns) servo thread
period.

Ok, can you clarify on how to fix this? Is this a setting in pncconfig or do I go into the .ini file adjust it? Thanks a lot, Andy
