VESC and T500 Thruster - Problems obtaining right speed

Submitted by SIGURD on Tue, 2022-12-13 13:45

Dear all,

I hope that someone can help clarify some things for me regarding the use of the VESC. 

I am using the HD60 VESC and the newest firmware (6.0). 

I am powering it at 24 V from a mean well DPU3200 power supply.

I am using the VESC for an ROV project where I would like to obtain some feedback from the ESC, this is provided by the VESC, which also allows me to use CAN as communications which is also preferred. 

Balancing Throttle

Submitted by kstuck on Mon, 2022-12-12 22:31

Thanks to everyone who makes the VESC possible.

It never ceases to amaze me the things I find that a VESC can control and the commnunity around the VESC project is amazing.

I was wondering if there been any thought to adding throttle control in balance mode?

This is not needed if you are doing a one wheel type skateboard but makes thing much easier if you are building larger diameter balancing wheeled vehicles that you sit on and ride.

Kill Function - Analogue Input

Submitted by austrobots on Sat, 2022-12-10 12:19

Hello. I am intending to use the analogue input as a kill switch for my VESCs. I was hoping to pull AD1 low with a 5k resistor to ground an then enable it with a 5V input from an Arduino (via a safety lanyard switch).  I can not see in any documentation what the "high" value is for the analogue input. Will 5V be high enough to pull it "High"?

Bldc generator voltage control

Submitted by Gsorter on Fri, 2022-12-09 23:52

I am building a hybrid drone, using a VESC controlled Flipsky 80100 7kw motor as a generator. I hope to generate 5kw of useful power. I have a 12s1p  35 amp 4000 mah Lion battery (in parallel with the load and with the VESC output) to both buffer the power for big manuevering surge loads, and provide an emergency source should my gas engine die.

I plan on using FOC control, but need to ensure my generator voltage never, ever goes above 50.4 volts (12x4.2v). So, with that in mind, 

Why is my VESC Speed (in MPH) half what it should be?

Hi all.

I've just installed an FSESC 4.20 Dual 100A in a WowGo AT2 and everything is running really nice so far.

The only thing I can't figure out is why my MPH speed display is halved... 

Im using a Maytech MTSKR2005WF controller over UART. On this controller you can have it display the data its getting over UART, like Speed, Voltage, Mosfet Temps, Distance traveled, etc...

Power cutoff without any warning

Submitted by TylerWilson on Fri, 2022-12-09 06:37

So I have recently built an euc from scratch and I decided to use a flipsky 75100 running off a 13s battery. Well my first problems arose instantly when I couldn't get the motor to turn with keyboard controls only it making god awful sounds. Well I managed to get it to work with the balance app usign a mpu6050 external gyro/accel. Then I started having issues of it randomly starting to tip over and when I got this to happen while connected to my computer the live gyro reading were showing the angle was way out of wack and the accel was reading -8 g's in each direction.
