Hello,

I am using Roboteq controllers since a long time and I have an issue with your new software.
I am using SBL 2396S controller and with I was working with the FW 1.8d without any big issue (except one the motor does not run quite well in both direction) so I have updated the FW to the new 2.0 version and now after few second the driver detect a short circuit.
So I cannot use anymore your controller as I can't go back to the 1.8d revision.

Do you know how I can solve this issue?

Have you been able to get this issue fixed yet? I have been having the same issue. I'm using an HDC2460, and it's my channel 2 when giving a negative command it starts detecting a short almost immediately. I have tried changing the motor leads and it still happens with negative motor commands. I also tried switching my motor 1 and 2 and the channel 2 still shorts with a negative command.

Hi DPosterick,
No I haven't found the right solution, in the past on SW 1.8d there were no issues but now it seems that this protection/detection is more sensitive in newer SW version.

I had this same issue yesterday with a GBL2660E after the same firmware update, found your post, and contacted customer support.
They gave me the following commands to disable the ethernet controller and it resolved the problem

>>> The possible option is to disable Ethernet capability on the controller. To achieve that we have to send in the Console tab the following three commands in a row

^LEG 1
%CLSAV 321654987
%RESET 321654987
After the restart the controller should be recognized as the GBL2660 (no Ethernet capability).

Hey Craig, thanks for sharing the solution. It seems that we perform bitwise oepration to change LEG register. What is this LEG register for? Is there any documentation for it, I could not found them in the datasheet.

Thanks Craig for your post

I have a question for the support guys, can we use this solution even if our controller does not have the Ethernet capability (SBL 2396S)?

So this procedure is not working on a SBL2396S with SW 2.0
