Tired that setting again no luck. I am going to try all the offsets next with those settings.

One thing if I test the encoder offsets it will move slightly to find the encoder then falut with a commutation error. BUT I have also tried all 6 combos of the hall seqence and it stays the same.

OK all leads together you get smooth drag no cogging. Any 2 leads together  and you get 4 clogs.

The motors are

Sanyo Denki  P50B08100VCKS7  1kw  Serial  06119001

There is VERY little info out there that I can find.

SHould be 8 poles if I am not mistaken BUT I have tried all the  pole settings as well. I am waiting on confirmation from Sanyo Denki of that value.

On the old servo drives (SDs) 2000 was the count and it worked fine as well in the MACH3 setup.

But I agree a wrong encoder count will cause the motor to jump(clog) on startup.

OK broke out a new one and same results. I have tried all 4 drives and same results so it has to be a setting somewhere.

The motor was new out of the box. AND I have 3 more new and 4 older ones off the mill. 

I will go out and open a nother new box(;-) and try that.

I will create a new file and try again.  The best I can do with testing is make the motor jump about 60 degs with auto tune and toggling back an forth with forward and reverse.

That seems to indicate a commutation error but there are ONLY 6 possible combinations to try and I have tried all of them as well.

I am thinking MAYBE it is a HALL offset problem . To my eye it seems the commutation is off by 120 degs but that is just my looking at the sequincing and I could be wrong. BUT I have tried 0/60/120/240/300 deg hall offsets ,all failed as well.

The drive ONLY stores 1 custom motor config, but in the software you can create as many as you like and reload .

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 (;-).
