Hi, I'm a bit lost... the max speed I get with the BluOSEC app or in diagnostics mode is 66km/h and the max speed is 37km/h with the KT-LCD3... as if the display interferes with the controller. I spent days trying to find a solution but I didn't find anything... Does anyone have an idea? Have...

Hi, the speed when unloaded is the same (35km/h). When I reach 35km/h the current decreases and I have no power anymore. The max current doesn't change anything.

Hi, I have a problem with my fatbike. The max speed I got with a 48V battery was 35km/h. I decided to get a 72V controller with a 72V battery to increase the max speed, but it doesn't work at all. The max speed remains at 35km/h. Does anyone have an idea? Here is my config.h Another problem ...

I have read it for a long time and I don't want to bother you stancecoke. Thanks a lot.

Thank you stancecoke for your patience... and for sharing your experience. I can't change the duty cycle of the PAS signal. Do I have to create an additional circuit? That's weird. I'm going to put a non-inverter follower circuit between the controller and the torquesensor. Regards.

Hi, how to activate this driving mode? PAS sensor with torque simulation and reverse step detection In this mode, I just need a PAS. No Torque sensor, no Thumb Throttle. Am I wrong? What are the most important parameters in this mode? Regards

Hi, is there a way to use the firmware without a throttle and without a torque sensor? My torque sensor is the problem of my system. The PAS works well but the torque sensor signal is dead. I don't want to use a thumb throttle. I'd like to know if it's possible to use my bike without a thumb...

I got it. You can limit you battery current to 50 amps, it's no matter for the 18fet KT. Each mosfet supports 150 amps and there are 3 mosfets in parallel. But it could be damaging to your motor. Regards

There are something wrong with your table : speed = radius times angular velocity (speed in m/s radius in meter and angular velocity in rad/s) With your values : 26 inch wheel : speed = 27.4 m/s = 98 km/h !!! Mechanical power = torque times angular velocity (power in W, torque in N.m and...

Hi, I don't know what kind of motor you have, but 20 amps in a motor winding is already a lot. If your motor is a 1000W, a 16S battery provides 60V power = voltage times current => current = power / voltage = 1000/60 = 16.7A I would start testing 15 amps max for the battery current. If the...

Hi, I had the same issue : ui32_SPEED_km_h and ui8_control_state don't exist. Have a good day.

Yes I did. I think I was pretty accurate. Ok. I thought the firmware used the current sensor because the value is read in the program. It's only used for the zero crossing. Thank you. Have a great day.

Thanks stancecoke, I measured currents and printed out their adc values. For ui16_BatteryCurrent I obtain the equation: ui16_BatteryCurrent = 2.68 x I_batt + 315 For ui16_adc_read_phase_B_current I obtain the equation: ui16_adc_read_phase_B_current = 2 x I_phase_B + 511 I'd like to limit the...

Hello, in diagnostic mode, when I print out ui16_control_state, ui16_BatteryCurrent, ui16_current_cal_b I get : 28 316 315 without pedalling, weird??? when I pedal and brake, only ui16_BatteryCurrent increases. Is that normal? It doesn't seem correct. To tell the truth, I'm a bit lost... I...

Thank you stancecoke.
