Has anyone did this hookup yet. Been a long time here since setting up any ac servos. The sanyos use a straight up commutation 120 deg hookup  abc/abc on the old servo dynamics drives but the ABs use a different sequence.  Can't wrap my head around the change in sequence to make it work.

I keep getting commutation angle errors (;-)

What AB drives?

I see part of my problem the UltraMaster software ver 1.60 I have will NOT allow one to modify the motor files. So there is no way for me to setup this drive to a custom motor.

Hi Terry,

Open Ultra Master Help file and look for "Setting Ultra Master Advanced Mode". This will tell you how to access the advanced features of Ultra Master. Custom motor creating is one of them.

Change the shortcut target to C:\ULTRAMST\ULTRAMST.EXE /A then open UltraMaster from that shortcut and in File menu you will see Edit Parameter Files.
If however you  do not have any commutation signals on your motor you will not get very far.

HIYA Hood yes I found your software trick with a web search. The  /A switch did the trick.

Worked out the commutation problem . Now I am trying to test with vel mode testing but I get a overspeed fault. The input field for setting the rpm will not take any values keeps sayin to enter a value between 0.0 and 0.0 .  I ener 100 but it rejects it.

Auto setup does not do anything yet(;-) Clip on start but nothing happens yet(;-)

Working on it. The AB software is strange compared to the old servo dynamics setup program (;-)

What have you got set for the RPM, see pic.

HUM I don't remember that screen anywhere. Let me check again.
