General discussion

Hello,

I am building an electric surfboard using the vesc6 controller.

I am looking for a simple solution to have the power shut off when I fall off. The idea being to minimize the likelihood that I get sliced by the propeller when I fall in. 

I was thinking of having a switch on the input power from the batteries. 

I am worried though that a sudden input power shut off may damage the vesc or parts downstream?

Would that be the case, any recommendations?

Thank you

hi

is there anyway in a dual vesc setup. to turn one off to save power (eco mode type of thing) ??

thanks

For my application, the VESC is buried in an enclosure and is being commanded by a microcomputer via CAN. I often need to replace the wheels and it is not ideal to have to disassemble to the robot and break waterproof seals in order to re calibrate the VESC to a new motor. Has anyone tried to calibrate their VESC  without a PC running VESC tool? It would be convenient if the steps could be commanded over CAN from a micro controller. 

I have HW 4.12 SW 3.40 VESC from maytech.

using it with pxhawk, I, controlling it with PPM signal, the vesc and pixhawk looks OK, but the signal read at VESC is not correct.

the px4 is sending 1.5ms(checked it.)

but the vesc is reading around 1.3ms~

I can change the start and End value, but the real problem is that

I want to control 3 vesc with 1 pixhawk output pin, and it changes when I connect multi VESCs.

anyone can guess why this happening?

I’m running my VESC6 with Hall throttle by using COMM 5V ADC1. Unfortunately, VESC tool can map only up to 3.3V, so I can’t use full range of my throttle.

On my other setup with VESC 4.12 and BLDC TOOL I can map and set Max. V to match my throttle at about 3.85V and use full range.

It looks like VESC tool is limited in that respect.

Can VESC TOOL be brought to the same level as BLDC TOOL?

Hey guys,

I want to ask you if it is possible to detect the position of the rotor with a resolver technique. I did not find any possibilities in VESC tool.

If it is not possible: Can I transfer the actual position (from a Resolver to Digital Converter) to the VESC, so it can regulate the position?

I've got a vesc6 running the latest firmware, in my E-bike (DD hub) using 2 hall sensor throttles on ADC 1 & 2 for brakes and throttle. (No reverse). A nrf51xxx Bluetooth adapter wired into Rx and TX. 

I'm trying to connect the android version of the vesc tool.  I see the bluetooth adapter and it initally connects but then gives the error "could not read firmware version..."

I've tried changing the baudrate from the default to 9600. And tried switching the Rx & TX cables on both baudrates. The error was the same. 

hi

recently the ackmaniac app kind of stopped working , it connects but would only read the min and max settings but received no other info like battery voltage, motor current,speed.

i updated to firmware 3.40  now it does nothing other than connect .

anyone have any ideas as to whats broken ?

Hi guys,
Does anyone know how to translate hall sensor values from BLDC to FOC?
For example, my current hall sensor values under BLDC is: -1, -1, -1, -1, 1, 3, 6, 4 and I want to input this value into the hall sensor table under FOC mode in such a way that it would understand. Based off of some research, I know that a -1 or 0 value in BLDC is equivalent to 255 in FOC. But what about for other values like 3, 6, 4, etc?? Is there a conversion table available to show which values in BLDC corresponds to values in FOC?

I've connected vesc to my laptop and I tried to update hardware to 410&411&412 version. I thought that everythink was all right, becouse laptop was connected (serial) to COM5 and it was written Fw:3.40, Hw 410. So I tried to set up motor setting wizard. I clicked bldc type after that I set up motor current limits, battery current limits. I choose voltage limits. After, I choose no hall sensor. And I tried to detect bldc parameters. I saw that motor is not spinning and then in my computer was written that detection failed. After that vesc is not working.
