I had ZERO issues on 23.46, DIYd a temperature thermister on some motor and then I observed some throttle glitchyness…
Alan had the same… @drone001 had the same issues… he turned off temp sensor throttling and now zero issues…
I could do the same or upgrade to V5 beta… but I’m going to attempt to wrap the sensor wire around the phase wire runs to clean up the noise caused by long runs of parallel phase and sensor wires… and maybe copper foil shield the sensor wire… FIRST
just wanted to add that i had a friend whos board was saved by the thermal throttles this week.
he was out riding and started to loose power. stopped to check everything and one motor was scalding hot.
Turns out one of his gearbox’s shifted somehow and was causing loads of extra friction. but thanks to the thermal throttle no lasting damage was caused.
I usually stop when I smell burning enamel and grease… hahahaha but this is a valid point! @DEEIF hand check your motor temps, especially on a new build, until you get a feel how they run…
I have been running FW 23.46 without issues on some TBDD’s. I generally don’t hit my temp limit unless I’m doing repeated drags on 80 amps so I rarely have a chance for temp throttling glitches. Also, this is the first I am hearing of this so it’s news to me. Lightweight, flat roads FTW!
I would start with checking your connections, make sure nothing is shorting out. Sometimes it’s a bad connection that causes issues with detection. Is it the motor making the odd noise? If so, I would swap the motor to the other side to confirm it’s the motor and not one side of the Unity acting up.
If your comfortable, you could also check the PCB underneath the orange cover of the Unity. You could also reflash the firmware but make sure to follow everything carefully so you don’t brick your Unity.
Start with your connections first, no sense in messing with something that doesn’t need to be messed with!
This is what’s happening and like I tried almost everything and one thing good is that my motors are not the problem. Its the focbox. Apparently one side of the motors can calibrate and the other side could not.
Sooooo… i got everything hooked up for the 4wd setup via can with a 10ohm resistor on the 5v. Turns on fine, but when I try to turn it off I get a DRV error, red light flashes 3 times pause, 3 times pause for about a minute and then the board turns off. Any ideas?
