Success driving Panasonic Minas S (MUMS) brushless motors

Please excuse a short commercial plug....

Dave Engvall gave me a Panasonic brushless motor at the CNC Workshop to 
see if I could figure out how to run it.
It took me a LONG time to get around to figure it out, but I have 
finally got it!  It has a serial output that contains the commutation 
signals, so I have to add a little decoder for that signal.  Otherwise, 
i have gotten it to work with my Universal PWM Controller and brushless 
PWM Servo amp.
It works quite smoothly, better than a number of other brushless motors 
I've tried.

The motor I have is a Panasonic MUMS042A1A, but I would assume all the 
motors in that "Minas S" series would work as well.

The Panasonic encodes the 3 commutation signals with a UART, sending 
8-bit serial bytes at 1 Mbit/second.
So, that was quite easy to decipher and design a simple gizmo to convert 
back to the standard UVW commutation signals.
These motors have traditional ABZ position encoders.

On the proprietary Yaskawa motors made for their own drives, the encoder 
only has 3 channels, and encodes position AND commutation all in those.  
A and B are normal, but the C channel flips the phase relationship 
between it and the other two to give commutation and index pulse 
encoding.  I got the general idea, but I can't say I understand how it 
works.

Jon and Dave,
That seems to be a nice small motor/ drive combo. I have 4 of them.
I have one of the drive/motors running on a Motenc lite board. Other work pulled me away from it. I need to get
back to it and tune the drive.
