Error Calibrating Motor Zero Current
« on: January 01, 2025, 10:50:26 PM »
Been installing a lot during the holidays and got an LM-3s installed in a Proto 2000 GP-7, sound works, front and rear lights work but the locomotive does not move forwards or backwards. I wanted first to determine if it was actually the locomotive so I disconnected my PWR-56 from the 24" piece of test track I have. I then removed the LM-3s from the 9 pin and 6 pin harness and brought out a regular DC transformer. Turned it on and set it at about 50% speed and touched the two wires to where the orange and grey harness wires connect to the motor and the locomotive moved. So I know it is not the motor but needed to see if there was a problem with the wiring harness. All my solder splices are sound and I have shrink tube over all splices. I inserted the two wires from the DC transformer to the 9 pin where it connects to the LM-3s 3 in from each side where the orange and grey wires attach and the locomotive motor moved so I know that the wire harness is good too. This narrows it down to either something in the LM-3s that is not working properly or something in my motor control settings that are not allowing current to go to the motor. Any suggestions I might try? I have not done the speed test yet as I usually first connect up the wire harness to the locomotive with sound (brown wires), the power in and the motor connections then connect up the lighting wires. When I check the "Information" section I get "Error Calibrating Motor Zero Current".  When I touch this part of the screen it suggests returning the module to Ring for Repair.

I missed this post. Sorry Coupe633. Did you get this sorted yet?

It's definitely not an error I've seen before. From the error message it sounds like an issue with the motor but then you say it suggests returning the LM to Ring for repair which kind of puts paid to that thought. I'm guessing this was a hardwire install?
