Motor won't start after Emergency Off which occurred while motor command was zero

Hi there,

we're using sbl1360 controllers and have a problem. The Controller is configured to use only serial command. If you start the motor, hit the emergency off button at the top right border of the roboteq control software, the motor stops as expected. If you press resume, the motor starts as expected.

But if you press the stop button, (Motor command = 0) then hit emergency off, resume and try to start the motor. It won't unless you acellerate it a bit per hand. The control software tells motor current -4A. It seems like there is a braking active.

It also seems that this only occurs, if the motor is standing still when emergency off gets triggered.

Could you explain that problem?

Thank you.

The controller is in open loop mode and doesn't issue any kind of fault.
I'm not using a script. I've attached my configuration.
I'm referring to the "Stop" button next to the "+" and "++" buttons in the "Command" Section.
Please take a look at the attached screenshots.

The controller doesn't issue any type of fault. Stall isn't triggered.

Should I create a video showing the issue?

I've created more screenshots.

The motor is quite sure in the correct UVW configuration. We connected the hall sensors 1:1 and then tried all 6 possible combinations for the motor phases. There were two working combinations. One for forward and one for backward. Exactly as the manual claimed there would be.

Additional I've discovered that the error only seems to occur, if emergency off was active for at least 4 seconds.

Hi,

I've tried this beta firmware successful. It works! When will the final version be released?

Initially, I've discovered the problem with this script, which allows free-wheeling if no motor command is supplied.
In our use-case the user presses a button, which sets motor command to 400. This seemed to work fine, unless the user pushed the button repeatedly.

This now also works perfectly.

Thank you!
