We’ve been working on shore power robots recently.
Recently I found a problem, that is, when I use the handle to control the robot, I increase the thrust to 100%, and the current is relatively large at this time. At this time, if I suddenly release the control button of the handle, the propeller will stop running immediately, causing the excessive current to the propeller to flow back to the power supply, thus triggering the short-circuit protection mechanism of the power supply.
However, when I tested some thrusters, I found that when I suddenly released the handle control button, the thrusters did not stop running immediately, but stopped slowly, and this part of the thrusters did not return to the power supply ( It may be possible to continue the residual current to make the blade rotate a few more times). Why is this?
Can I change some parameters so that the propeller doesn’t stop immediately when I release the control button, but it makes two more turns and stops slowly?
