SBL 1360, does not stop when motor does not move

1 year 11 months ago #29533897 by ahmedrghazi
For my application I am using the SBL 1360 motors for a differential drive system. I have the problem that after a certain time to use, (approximately 50-60 minutes), I end up in a situation where the motor controller is being given a command velocity, and it keep generating a current even if the motor does not move and no error is reported. If the command velocity is removed and is given a command to move in the other direction then the motor moves again. Why it might be the case and what can I do to detect the error and fix the issue?

I'm having a bit of a hard time following your issue. You say it gives a motor command and then generates current, but the motor will not move? This should generate a stall condition, but it is possible that you have stall detection disabled.

Let me know what kind of motor you have and how you are driving it. The two settings I am mostly interested in are the switching mode and the operating mode.

I have elmo brush-less motor and am controlling it using the ROS roboteq driver.

"The node works by downloading a MicroBasic script to the driver, which then publishes ASCII sentences at 10Hz and 50Hz with the data corresponding to the Status and per-channel Feedback messages published by the driver."

You should check to make sure the messages are being properly received by our controller by connecting to it in Roborun+.

That part is working well.

Do you think you could create a log of the motor command, motor power, motor amps, and motor speed values? You should be able to do this from the run tab of Roborun+. It will help me see what is going on.
