I have an AMC1280USB with a version 4 extension board. AEAT-6012-A06 sensors are hooked up correctly and I swapped out the UDN2981chips to the ULN2803 chips and moved the 2 jumper settings. Motor max speed set to 100% and minimum to 0%. Controller set to 8 bit analog output. Inverter is a WEG 10 and also hooked up correctly. When I power up the inverters with the controller running I get no reading on the display for the sensors and the motors start turning at lowest RPM without stopping. Changing directions on the sensors makes no difference. PID settings are good. Running firmware version 3.5 and using the hexpod 6DOF software. If I choose "Connect to Hardware" the motors accelerate to 100% and then gradually reduce speed to minimum RPM again. I have no idea where to go from here. My platform is ready and I cannot get it to work. Any help would be greatly appreciated.

To your issues, can you verify you fixed the little issue with the missing trace when using the SSI 12 bit sensors? If not see these videos please: www.youtube.com/watch?v=Djyzk-HAaKwwww.youtube.com/watch?v=9KIUbUZwfHQAlso can you tell me if you selected the 12bit analog input option in the LCD menu and if you choose 180 or 360 degrees range? Other options you should have set: Output as 8bit Analog Output type as Bi-directional Thanks Thanos

Hi Thanos,
Thank you so much for your reply. I guess I have the newer version of the board as the trace was already there and I have rechecked all of the connections. The output is set to 8 bit analog and bidirectional. I know I have the sensor set as 12bit SSI but the input I'm not too sure about as the platform is assembled at my shop and I won't be there until tomorrow morning. I do have them set at 360 degrees. I did, however, find a post on another site where there was a similar problem to mine and increasing the motor offline percentage to over 40% solves the problem of the motors continuously turning. I don't recall having seen the setting available on my unit. I have Maximum Motor and Minimum Motor percentage. They are set to 100% and 0%. I noticed pictures and information on the older boards from your manual that say it is required to provide a separate 15volt supply for the signals but on my board the 15volt jumper is not traced and there is no place for a 15 volt input. The other pictures of the newer boards show the 24volt jumper in place. Not sure which way to go with this. I have checked both boards and there does not appear to be anything wrong with the chips or any of the connections but when connected to the 6DOF program I'm not seeing any 0-10 volts signals going to the inverter. I know I'm rambling as I try to explain everything I have tried but I'm kind of at a dead end on what to try next.
Thank you so much.
