General discussion

Hi guys. I'm new here :-)

I'm about to integrate a VESC in my scooter conversion project.

For material protection and safety, I'd like to disable the throttle while braking. 
Is there such an interface and function in the VESC 100/250?

Thx for your help.

planning to use a regular ebike throttle (hall). Do I connect it to the comm port - ground, ADC1 & VCC (is the vcc 3,3v?)?

the bluetooth module is connected also to the comm port via Tx, Rx, ground & 5v? that means the throttle & bluetooth module share ground. is this OK? 

Hi,

Today for the second time I burned a maytech 75_300  with:

12S liions

Motor Hacker Q80 8M 8m

drived via pwm

freq at 50Khz or 60KHz

Ctrl : pid speed no reverse

Current limits set to +-160A

erpm final consign at 100360erpm

no breaking 

the pwm from my autopilot increase from low duty to high duty cycle in on step, i'm using a 40 seconds rise up inside the pwm app to have a smooth ramp.

can anyone point me to the place where the blink codes for the VESC are described? My new setup is blinking 5 times red when connecting the HAL sensors and I would really like to know what the error is - in the tool I see no error (Fault: NONE)

Hi,

I'm trying to migrate from castle creation BLDC to vedder Maytech 75_300 FOC but not without any problems. I'm using 2x 12S8P li-ion batteries in // and a hacker Q80 28 motor (kv180, 5500W in burst).

Without blades, it seems working to run to the consign (speed pid without reverse, or current, foc or bldc). But with small air drag test blades an oscillation arrives during the increase and vesc stop abort increase. I need to increase to 105000ERPM. I set the frequency to 50KHz.

Hi, let's say someone (maybe me) made their own VESC based hardware and was so dumb to mess up the pins from the stm32 to the gate driver... so now STM-L -> GateDriver-H and STM-H -> GateDriver-L same for phase U ,V and W.

I don't want to make a new PCB if there is a chance to swap the pins in software or maybe it's sufficient to change the ADC timer from Up to down Count ?

We’re controlling the VESC HD60T with PPM now.

But when running the motor, the output dips on the CAN status interval.

Setting the CAN Status 1-5 to Active on a frequency of 1Hz, we can hear and see the motors being interrupted for a short time.

It almost looks like the VESC can’t control the motor while sending the Status?

Is there a way to fix this, or prioritize the PPM before CAN?

hi guys

very frustrated with this vesc tool

cant understand why its so unfriendly

tried download 3 free different version that i found online 1.1  ,  2.1  ,  3.2  i think was not able to connect them to my flipsky fsesc 75200

claiming too old version and at the same time don't allow me to update the firm work.

the 3.2 version claim i didn't read all of the interaction? and didn't allow me to continue installing the window version on my laptop.

Hello,

Please see image below. Sensored-BLDCs for RC cars allow you to adjust/tune the hall-sensor's angle. I wonder if someone can point me in the right direction on how to calculate the sensor angles. There are some electronics/analizers that determine the Sensor's angle but I will like to do it with a VESC. 

I honestly can't find any information online on how to do it; but I've been doing some testing and I think is all about timing comparision between the commutation and phase voltage. Does anyone know if I'm on the right track? 

Hi,

Is is possible to use FOC without any braking current (like in other bldc controler)

I mean when I set braking current to 0A, engine never stops ? I do'nt understand since there is some fiction behind the motor so it cannot continue to turn without eating current !!!

Nota : My battery BMS is not reversible... how can I do ?

Thanks in advance,
