VESC 4.12 - Current limited at 100A

Hi All,

I used to run my VESC 6 with a motor current of 120A to power my e-bike without any problems. Currently I'm experimenting with a oil cooled VESC 4.12 to use the same current. But for some reason I can't set the value for ''battery current max'' or ''motor current max'' higher than 100A when connected to the 4.12 in VESC Tool. It just sets itself back to 100A when I write the motor configuration.

Does anyone know if this is a safety feature? And if so, is there a workaround?

UART Safety Feature

Hi Everyone!

I'm wondering why UART Mode only doesn't have any Safety Feature that comes with PPM Mode. Like Timeout Brake Current, Throttle Curve, mapping and so on.

UART is definately a more reliable communication type than PPM because of the CRC check.

ERPM scaling / Maximum motor speed / RPM

Hi All,

Newbie here so be gentle !

 

I am configuring a FlipSky FSESC 6.6 and 772KV 4 pole motor with the VESC Tool.  I am running in FOC mode using a 13.8V power supply.

I am unable to achieve more than 17,000 ERPM at 100% Duty.

I'm told the same motor has run at higher speeds using a different manufacturers controller in BLDC mode.

 

My question is...

Is the relationship between Duty and ERPM purely a function of KV or is there another scaling factor in play ?

 

VESC Tool Android - Real-Time Data per controller or combined?

Title, basically. Couldn't find precise information so I thought I'd ask a quick question:

 

In a two-controller setup with a CAN connection, are the values from the realtime tab inside the VESC Mobile app combined data from multiple controllers or just from the currently connected controller? E.g. should I read the power draw as is or should i multiply by two if i run two VESCs? And what about Ah drawn? Fault Codes?

vesc tool crashing on 29aug19 - website down/link?

hello all - i tried using my free copy of the vesc tool from two devices yesterday, to try and discern why it was crashing about a minute after starting - both installations exhibited the same behaviour, and when i tried connecting to this website in case there was a known issue, i discovered that the website itself was down - is the free version phoning home (authenticating against the website)?  i would like to contribute to the platinum version and recognise this great tech gifted to the community - i notice that the platinum build is a later version as well, so perh

Wrong Motor detection values after STM swap dual vesc 6

IMG-20190817-WA0006.jpegHi, after a short on one site of my dual vesc6 3.3v rail, i managed to swap the stmF4 and one 3.3v LDO. Chip is one of my Flight controller from my Fpv mini quad The green lights working again using stlink v2 But the motor detection gives to high values. Resistance on the bad side is, Motor R =950mohm while the other working side is 9mohm. The values for Motor L are fine. Motor flux linkage sometimes 0 mWb on bad side.
