I’ve been using a jrk 12v12 motor controller to drive a windshield wiper motor, with great success. It worked very well, and never pulled too much current. But the motor was a little too light, with a poor shaft interface to work with.
So I bought a heftier motor with a stronger shaft and gearbox. But that does not work as well. I had the current limit set at 15 Amps, and it got triggered. I boosted the current limit up to 29 Amps, and no longer get any current limit errors.
But I do sometimes get Error 0.0004 Motor driver error. That happens even when the motor is moving normally, far from stall current or startup surges. And the controller seems to be getting hot, even though I’ve tried to monitor (using the JRK Configuration Utility) the continuous current being drawn and it seems to be below 10 Amps.
Could the “Motor driver errors” be caused by too much continuous current being pulled? What else could cause those errors? As mentioned, they do not happen when a lot of current is being pulled in a surge. Quite the opposite. They happen as the motor is running normally.
If the new motor is just too big for the jrk 12v12 motor controller, do you have any suggestions? I use the feedback feature and the PID tuning. Your motor controller is very nicely done. I don’t know what I’ll be able to use as a substitute.
