OK, you don't use the latest version of the java configurator from github?!
No. But now I think I should update. :D

EDIT: Which I did just now, flashed again but it didn't change anything :(

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

is like russian roulette :-) have you checked the voltage of the brake-signal wire? It has to have 5V (pullup from processor) otherwise the processor stops during booting. regards stancecoke Brake= vin 4.5V, signal 4.95V Hall= vin 4.5V, signal 4.95V PAS= vin 4.5V, signal 4.95V Throttle= vin 4.5V, s...

I'm afraid I don't have any other places for you to check. Thank you for helping me. I guess buying these controllers from Aliexpress is like russian roulette. You hit or you miss. :?

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

Did this soldering extended legs to pcb and used external 12V input. The output pin gave 4.99V so the chip seems to be fine. OK, then check if the LM317 IC is working properly by applying 20v on its Vin pin and checking if: - The LM317 output reaches 13-15V - The 78L05 outputs 5V properly again (in...

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

It's 4.5V without sensors connected and with sensors it drops to 4.2V. Well, then I suggest you checking the 78L05 IC in a separate circuit, if possible, to check if the chip can generate the 5V properly.

What's the reading of the 5V rail with the Hall sensors disconnected? Is it near 5V?

Have you tried to use the BlueOSEC app without the hall sensors connected?
I have. No difference whatsoever. Blu OSEC doesn't read anything. The hall sensor output is 25mA if that's relevant https://components101.com/a3144-hall-effect-sensor.

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

Hm, what do you mean with Vin? Just a voltage measurement from the controller power cables, when battery is not connected to those. Probably irrelevant. Charged caps, right? If you connect the battery and short red to blue at the display connector, the voltage between the red and the black wire of ...

If I want more power to S06S, can I just replace my 36V battery to 48V(52V) and change the undervoltage limit from OSEC? Anything else I need to consider before doing this? Specs at the signature.

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

With a blocked motor, the phase current limitation will be active. You could check the control state, to be sure. Use the brake of the bike to keep the speed at e.g. 10 km/h with full throttle, then you will see full amps. If not, you have to check your throttle settings throttle_min and throttle_m...

Should the BluOSEC show 15A at the screen when full throttle is applied and the wheel is blocked from turning? Does it ever get to the S06S maximum of 15A? If it should go there mine shows only 11.9A? Obviously then something is wrong here. Either my controller is not delivering the full power or my...

The motor is 36V Shengyi Hybrid Brushless DD motor. I don't know why it showed 11amps. Now its back to 1,7amps. I haven't soldered any sensors to the pcb. The controller is S06S from bmsbattery.

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

No update, technical restriction on how "not set" == 0 is handled in eeprom settings. I see no practical use case where 1km/h is a problem that would justify a complete refactoring. So I have to use the Java tool and put 0 to the "Without PAS" -section, flash again and I'm set?

No, please don't do that. It's clearly stated in the wiki as well. For every additional watt you pull out of the 5V rail the linear voltage regulator inside the controller has to !burn! ~5 watts (depending what kind of resistor the poor chinese guy had at hand botching together your very controller...
