Any help would be greatly, no massively helpful. Cheers!
Check that PAS is not "0".
Try to activate "6KM / H power assistant push function"
Try turning on the controller without a display. (A jumper in the connector).
Check the pins in the display connector.

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

How did you measured this currents? Measured Tektronix A622, current in green or battery (13s) wire. The voltage is about 50-52V. I loaded the wheel with a disc brake, in time it is a couple of seconds and the controller turns off the motor (8fan bpm 10t). Pictures for the initially locked wheel an...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

Thanks. I expected it around 50-60A max. Perhaps in the original, it can give out more than 70-80A, but it will surely get hot even from lower currents. C5, but I didn't watch it. I don't understand the simulator. In my understanding, there are 3 phases in the motor .... if you count the rms, then ...

Do you know in what range is the phase current of these controllers with the original KT firmware? Like 2.5x the battery current or so?
I had a phase current amplitude of 70-80A.

You need to read the kt-lcd3 manual or from another kt-lcd.

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

Hello. Can the "wheelsize" value in the KT LCD protocol be calculated (does it mean something)? Or just decrypt according to the table?

Also what is L1? lcd8 manual: "L Parameter Setting 1. L1 parameters are applicable to the automatic under-voltage controller.

The final xor 2 required in the crc calculation varies, even for exactly the same message but at different sessions/times - sometimes an even number in the final xor is required and sometimes an odd number.
CRC = (xor B1,B2,B3,B4,B6,B7,B8,B9,B10,B11)

Hi
How to check supports stock controller sensor temperature of the motor?
Perhaps you have a stock controller circuit supporting a motor temperature sensor?

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

I bought this same controller from topbikekit. Have you used it yet? Any results? Did not touch the waterproof fill. Therefore, I use it in stock. Bike and I are about 100kg. Motor bafang BPM 10t 26 ". 48V. It starts moving away if the gas is lightly pressed, otherwise the current exceeds and switc...

I have a similar controller with 9 * K150e09NE. At the start, turns off the motor when the battery current is 20A. In motion with a battery current of approximately 25A.
Phase currents up to 80A.

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

Hi
I got KT48SVPRM-XFCF06 (board KTE-9S5-J5). It has 9 transistors K150E09NE. Processor STM8S105C6T6. Current sensor acs711 (QFN).
Is it compatible with this OpenSource firmware?

What are the extra 3 transistors doing?
