    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Hello, does the tsdz frimware can be used for other motor such as XF motor ? 36v250w TS controller XF motor run smoothly with original firmware.u/v/w phase wires ,hall wires,throttle wires were connected,but without the LCD3 display and pas . I downloaded the KT-LCD3-v0.18.2.hex and...

    Hi， When I start to ride under PAS mode, the motor works intermittently, with a creaking sound. Yet when I speed the pedaling up, the abnomal sound disappear and it goes smoothly.Do I have to worry about parameters？ PAS magnets：5 timeout：3125 ramp end ：1500 or 18750（10rpm） ramp start：64000 pas...

    FOC was disable and the waveform was still asymmetrical.i tested other brands of controllers，there were all the same. maybe it is normal. what is the angle interpolation used for? #define DO_INTERPOLATION 1 #if DO_INTERPOLATION == 1 ........ is the angle used to adjust the rotor position...

    I can recongnize a obvious resistance while riding or pushing my bike(the controller was powered on) . i exchanged another controller and the motor without resitance(the controller was powered on). So i choose “diagnosis” mode to konwn the controller state，when the controller was powered on...

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

    the controller was powered off，rotating motor was easy. the controller was powered on, i felt resistance when i rotated motor by hand , so i think the motor should be rotated smoothly without resistance even thought the controller was powered on（didnot rotate throttle）. I had tested,but...

    I pedaled a little hard when the controller was turned on ， without throttle and PAS. the motor maybe working,are there some setting to avoid that? :D

    it was sinosodial controller.And there was a strange phenomenon the throttle was full but the motor kept standstill，just like the motor stopped at special position，the motor couldnot be started.

    on the road when i turn the throttle to the end，the motor may take a 3-4 seconds and increase slowly to the max speed,not a quick response.do you?

    Hi casainho ， Could you tell me the relationship between Phase A（SPWM） with Phase Asv（SVPWM）？and how to calculate them？ the numbers in ‘Phase Asv ’column are different with the firmware，are they be suitable for use？

    Thanks. I'v changed the hall order in the code three times，(such as 1-3-2-6-4-5,2-6-4-5-1-3,4-6-2-3-1-5) and also exchanged the wire combination,so motor was forward(cw）and quiet every situation，but the hall order was still counterclockwise on the APP.It's strange.when the hall order...

    Maybe my direct motor hall order is counterclockwise .when the order was clockwise on app,the motor run reverse even though exchange the phase wrie or “motor.c"--hall order.
