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

I'm building a 2wd e-bike. For the rear motor I have S06S and for the front motor I have KT36ZWS. Both systems have individual batteries(36V) but share the signals of throttle, PAS and brakes. I'm using either two individual HC-05 bluetooth modules or just a single one with a manual dipswitch to cha...

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

I'm planning to put another motor to the front. I have S06S -controlling the rear DD motor and KT36ZWS controlling the front geared hub. I want to use separate batteries for each of them and share the signal wires from throttle, PAS and brake for both controllers. The instructions state that KT36ZWS...

Offroad mode can be activated by the brake lever as known or by a "magic" touch to the smarthphone screen
More info about the "magic" touch please if it's still implemented into the app. Thanks. ;)

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

:thumb: Is the motor still braking that hard, if you stop pedaling? Please try this on the road, as with wheel in the air, it is not representative. Ok. I took a spin outside with the bike and it feels a bit more responsive. The original problem didn't seem to change much or at all, though. I'm als...

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

Cal b seems to be correct. For a S06S Cotroller cal a has to be something about 100. Ok. Changed the battery cal a value to 100 and now the battery current and target current match very closely. I think your video is in Torque-Simulation mode with highest assist level?! Yes. I understood that torgu...

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

No, this seems to be a matter of the current cal b value, that is set automatically at startup. Please check battery current and current target, in the situation, when the motor should turn free. regards stancecoke Ok. So BluOSEC screen shows; Battery current = 0,2A(46/314) when standstill, and whe...

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

Hello. I'm having this annoying feature at the moment so that when I start pedaling, the motor assistance kicks in pretty close to my liking(about 1 sec). But when I stop pedaling and the assistance shuts off, my DD motor slows dramatically and makes the ride a bit like push and pull. What settings ...

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

What can I do? It is obvious that you are using a PAS with an internal direction detection. PAS pulses are only generated, when the pedals are turning in the right direction. Just turn your PAS disc on the bottom bracket shaft, so that the arrow on it points to the opposite spin direction. Then it ...

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

PAS threshold: Threshold for direction detection from the PAS signal. The value should be the arithmetic mean of the reciprocal of the duty cycle of the PAS-signal during forward and reverse rotation. The appropriate value can be determined by trial and error or by looking at the displayed values a...

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

I'm not sure why this is on in the first place, did you uncheck the "clear eeprom" checkbox? Better explanation of the checkbox function would be needed. This might be obvious but to make things clear, you have to leave it checked or uncheck it when flashing new settings to the controller?

Ok. After flashing the open source fw I'm not able to run the motor at all. I have tested the whole system before flashing so I know everything should work. What would be the best route to start troubleshooting my situation?

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

Lot of questions; Is the PAS assistant at the 0 assist lvl by default @ original kt s06s firmware? So, to get the PAS working I must either have a display with buttons to turn it on or configure the firmware? And for this, I must use the open source fw? So can I test PAS without display or just the ...

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

Matters only what current you set.. 25 should be ok as peak. But you can't still hold full throttle. Yes, I totally forgot that the firmware gives the option to lower the current from the controllers max draw, doh. What happens if I full throttle then? Even stock fw can be set to half the full curr...

Just for the clarification; is the S12S's 25A max current too much for these cells? I calculated the c...
