AX2550

I have a Roboteq AX2550 and it was in worling order when tested. I believe it was using version 1.7 or 1.7a firmware at the time.

I have updated the controller to version 1.9 and now after reconnection the control does not seem to work.

Checking Roborun i am not able to make the driver drive the motors(2). Everyhting seems ok except for one item and that is the BatVolt which seems to read in the 0-3.0v range. I have checked batteries and they are delivering 24.00 volts. Internal volatage is listed as 11.6V

As i try to make the motors move the BatVolt drops to 0

Is the controller damaged? Please advise where i can get it repaired, and is there a location in australia that can do the repairs?

regards,

Rob.

The battery voltage reading you indicate means that the 24V is not making it to the controller somehow.

Are you powering the controller through the yellow wire as well? If the controller turns on and reports 11V internal voltage, while you have 0V on Vmot, this would be the case.

The V battery reading is done practically where the wires come into the controller. There isnt much damage that I can think of that would cause it to read 0 if the controller was properly connected to power.

After reading your post i went back and checked all the connections again. This time i checked at the controller itself and there was indeed only low volateg.
Seems the power connectors i was using while connected were not mating properly in the plugs - refit and reconnected sorted all the issues - thanks very much for your help.
