I purchased the VSD-EX drive, the VSD breakout board, and BLD motor from you about a year ago while living in Mongolia. I have returned to the US and had some time to try and set this up on my test bench. I have read through all of the post and manuals and no luck getting the motor to rotate. This is a REV2 board. I am able to connect with the GD tools with no problems and I did a firmware update which worked with out a problem. I have checked and re-checked the wiring to the motor and nothing.

When I connect power to the board I get the solid blue light. I downloaded the motor config file for the 300 motor and when I hit test nothing happens for a 30 seconds and then the blue light blinks a couple of time and GD tools reports that no encoder counts occured.

If I reset the drive, the motor will rotate a few degrees in one direction and that is all. I can rotate the motor freely with or without power to the drive. If I rotate the motor by hand during the test GD tools reports that there is an encoder count that varies by how fast I turn it. I make one revoulution and I can get from app 4000 counts if I turn it slow to 300 counts if I rotate it faster.

I don't seem to have an issue with connections, I have power after the fues, a solid blue light. If I rotate the motor by hand the blue light goes out and the red light begins to blink. I am assuming that this indicates a count fault.

Any insight into what to look for would be greatly appreciated.

It's just probably a settings error. Please post saved .drc file from GDtool so I can check it.

Thanks for the reply. I am attaching the file that I was using. I see I did not include a lot of information about my test setup. My connections are the same as in the getting started guide. I have 12V input on the control and I have 30Vdc input to the HV+ and HV-. I think it is probably something simple but I don't know where to start.

I just discovered I cannot upload the file as is so I changed the extension to txt. Hope that works

Settings seem almost ok. One thing that might cause this is very low current limit values. Try putting at least 2 to 5A to all three current boxes and set fault current to 10A for instance.

Does motor shaft turn easily when blue is blinking at power on? Should not.

[2ndSteel]

Yes, the motor shaft turns without any resistance. I will try setting the current and let you know if it changes anything.

It is now working. I tried adjusting the current settings and some how got the blue light blinking which according to the manual means that the drive was disabled by the user. I could not get that to go off so I finally opened the original motor file and hit set and the drive reset and is now working.

Thanks,

Larry
