Can't program bricked Vesc 6 over SWD

Submitted by Rc 44 on Thu, 2019-06-20 02:16

I’m making a build with two Vesc 6’s that was working okay until I went to update the firmware. One worked flawlessly but the other one got its power disconnected in the process. Now I’m with one Vesc functional and the other one only with the blue light on, and I can’t connect to it with the usb port, which means it’s probably bricked.

Fault: FAULT_CODE_HIGH_OFFSET_CURRENT_SENSOR_3 on VESC 6

Submitted by Jackl on Tue, 2019-05-28 14:48

Hi there!

I am running a VESC 6 on a dynamometer with different Motors. Very small ones up to kind of large motors.
Power supply is two beefy 12V Lead Acid Batteries in series, so we are around 24V. Motors are run in sensorless FOC, with currents up to 60Amps.

Now, my Inverter suddenly stopped working and I get the Fault: FAULT_CODE_HIGH_OFFSET_CURRENT_SENSOR_3 on startup.

It does not help, if I disconnect the motor.

Hub motor e-bike not recognized

Submitted by olivierskypullc... on Tue, 2019-04-16 11:06

Hello everyone,

I have an e-bike whose controller is broken so I am thinking to replace it with a VESC 6 I have. The problem is I cannot get it pass detection. In BLDC auto detection it stutters, then beep and I get a detection failed error. The motor is an ABB 3-permanent magnet AC synchronous motor, wired in star configuration. I connected the neutral to the - of the battery. Its nominal power is 250W.

What can I do to make it pass detection ? I tried increasing duty cycle and current, it didn't worked.

Thanks in advance !

Good afternoon, I have made enquiry through the website but have not received a confirmation email. I am unable to proceed with purchase through the website as I get an error "warning ERROR GETTING RATES FROM UPS: FAILURE 111557 HARD UNABLE TO DETERMINE DESTINATION FOR TIME IN TRANSIT INFORMATION." on the website and cannot proceed to payment screen. Could someone please advise me on how to proceed as I am keen to get my order underway as soon as possible.

Many Thanks,

Jeremy

Iron less Axialflux Motor

Submitted by tobiokanobi on Sat, 2019-03-30 12:11

Dear Forum,

I've build a 3D printed Axial Flux Motor (okay the rotor is already made out of aluminum). The Motor has 24 stator coils (3x8) and 32 poles. (since the arrangement is a little different to radial flux it is really 32 poles (vs 16 pole paires). One stator drives two rotors (each has 32 poles). The diameter is about 160 mm. The windings are 3x0.8mm copper with 9 windings per coil.

VESC6 Issues: Battery current inaccurate, positive ramp time, motor current max.

Submitted by ESCam on Thu, 2019-03-21 22:50

Hello, I am experiencing some issues with my VESC6. Has anyone else seen these?

It seems to measure the battery current lower than the actual current to the VESC. I have verified with a power supply that the values in the RC benchmark window are accurate. The screenshot below is at max throttle, but it is inaccurate throughout the range.
