OK found it it is at 3000 rpm which is the upper limit on the servo motor by spec.

I will study this some more. I am not positive the commutation error is total fixed.

I worked out the sequence from an example of both sequences  and do not get the error on start up. But still have not gotten it to move yet.

Thanks for the help, (;- )TP

Use the Encoder alignment option to see.

HUM still missing something here, No luck.   Th epahsing seems simple enought BUT the halls do not exactly line up so there is an offset but how much? That is the $100 question.

OH well maybe AB will have some insight, Yea right

Soes the encoder alignment tool not tell you the offset you are needing? I think in the older drives (ones youhave) you can then tell the drive to offset it automatically.
If you want to align the encoder properly you can do it either via that tool or you can do it with a dual trace scope. I prefer the scope method personally. If you want to now the scope method give me a shout as I should have the info here somewhere, sure AlTheMan on the zone told me it years ago.

Fiddle some more with it and seem to have the commutation correct and the encoder show zero offset. So maybe that part is right now.

Still no movement when using the control panel to test . something in the motor file is preventing it from accepting a vel number . I can load an odd file (not for that motor and the vel number show up in the test panel.

I hack at it some more tommorrow.

I am suely missing wsome just have not figured out what yet )(;-)

OK no luck so far. ANY AB drive experts out there?

I have the spec sheets for both components BUT not enough brains to work it out.

You've got Hood here, Terry ;) Can't think of someone with more experience with AB drives around here.

I am more used to the newer drives but have used the DDM's and actually currently have one on the Conects spindle.
Post your details of the motor and maybe screenshots of your custom motor setup.

Here are the specs on the Sanyo Denki P5 motors.

What I can't get straight is the proper commutation AND maybe an offset of the Hall setup.

The Ultra software is on the shop puter so I do not have  a screenshot.  I have tried various combinations all failed to work (;-).

I presume you have U connected to pin 13 on the drives J1 connection , V to 14 and W to 15 and have left the U- V- and W-  unconnected?
Red motor wire to R on drive, White to S ,  Black to T and have the Yellow/Green to Gnd on the drive?
