I used two g2 24v13 motor drivers Pololu G2 High-Power Motor Driver 24v13 connected to two 24V motors (use 0.55A at no load, 3.55 A at max load, and 15A stall current).
And when I started up the motor drivers, one of my 24v13 drivers seemed to have fried or short-circuited itself.
I believe the reason was that the power supply that I connected to the two drivers was a 24V 15A power supply, and so when I tried to start both motors at the same time, they would draw 30A in total which would be too much, and apparently that was too much for the pololu 24v13 motor driver board as well.
The fault flag is now active for the board which as the info sheet says means that the fault is due to over heating, under voltage, or a short circuit. It’s definitely not over heating since the temperature hasn’t increased on the board, and I don’t think it’s under voltage since I turned off everything and started it again and the motor driver does show 24V via my multimeter. So I think something inside the board has short circuited (everything external to the board is fine).
Is there any way to reset the fault flag now and have the board work again? (the board motor outputs are all 0 since it’s in the fault mode). I tried pulling the sleep pin low, but that only seems to temporarily disable the fault pin. When I set the sleep pin high again, the fault flag is active again and the board doesn’t move the motor.
Also is my only solution for next time I try the motors again to use two separate power supplies, one for each driver, or is there something else I can do with the motor drivers that will prevent them from breaking?
