KT48SVPRK-ff01L controller with TF-01U display = noisy?

[vwrado]

I recently got a KT controller model KT48SVPRK-ff01L and using it with the TF-01U display. Both have minimal instruction manual. I am using it with a 3000w direct drive motor and even though it works, it doesn't work smootly. The motor is noisy. Does these controller have auto tuning capabilities? I read online that some KT controllers have 2 white wires that connects to each other when auto tuning. I do not have these wires. I also heard that some displays can activate auto tune but I am not sure how. Does anyone know what the parameters are for this controller (meaning P1-P4 and C1-C15)?

you'd have to check other KT threads, but I don't think KT has autolearn.

So you'd need to manually determine the hall/phase combination for your specific motor, swapping phases to get the direction you want, then halls to make it run smoothly at the lowest no-load current at the right rpm.

I've installed a mess of KT controllers with LCD1, LCD3, LCD4, and LCD11 displays, and none of them had learn wires or a learn mode in the parameters. The phase and Hall wire hokey pokey isn't all that fun, but it's not a big deal.

All the ones that used Higo or Julet sealed plugs (which I usually avoid) worked without revision, but none of the ones with JSTs and bullet connectors were fully color matched between phase and Hall wires on motor and controller.

It is known, that the Kuntengs have a resonance issue with big cheap direct drives. There are several reports here in the forum.
But first you should check, that you are using the right Hallsensor- phase wire combination.

Never bought the big units, but none of the 17A-25A models I used had self-learning. Their higher power square wave models are often sensorless though.

If you have a noisy motor, and have the discrete Hall/phase wire connectors. you might look at this chart.
