First steps with Pololu drivers. I have a setting with jrk G2 driving big 24V wiper motors controlled in position. I have to but quite low deceleration ration (around 10/20) to use it or the switching PS I use trips and I have to power cycle it (24V 300W PS but same problem with a 24V 700W PS or my lab PS). Works fine on batteries or with a discreet PS. I am thinking of putting flyback diode to kill the deceleration surge. Will it work ? Do I have better to put it on the jrk side or on the PS side to gain the cable resistance ?
Thanks for your answers,
I am answering to myself. Flyback diode doesn’t do any difference. I guess the current surge of the motor when turned on or off is too high for the switching power supply, causing them to turn their protection on. I have put two 38Ah batteries in series with a trickle charger and it works fine.
