Overcurrent fault

Submitted by tomriddle425 on Fri, 2022-09-09 06:48

I am using a flipsky dualfsesc 6.6, 12s 12c lipo (2 6s in series), on an electric mountainboard. I've been having a few symptoms that I believe may be due to an overcurrent fault, I'll start with the symptoms while riding, when motors are under load there seems to be a great deal less torque than there should be with 70 phase/motor amps per side, this issue is only while accelerating rather than braking, still recieving full brake torque.

Motor parameters constantly changing.

Hi all, 

I'm wondering what is a normal amount for motor parameters (particularly coil resistance) to change on each detection. If I repeatedly click the detect parameter button on the FOC page, the coil resistance may change from 85 to 87 mOhms, which I'm guessing is normal, however occasionally it may jump up to say 95, or even as high as 120. I'm pretty sure it isn't a temperature thing, because it isn't like it happens right after I've been running the motor a lot. Might I have a hardware problem with my Vesc or motor, or is this just normal? 

VESC 100/250 Voltage spikes?

Submitted by LondonNight on Mon, 2022-09-05 08:21

Hey, I'm new to the forum. I'm looking to buy the Trampa VESC 100/250, and it says on the product page that the controller is rated for 100V max, and that "Voltage spikes may not exceed 100V!", but I'm really not sure what that means. I'm not sure how I would go about figuring out whether this controller is suitable for the motor I have. I have a VEVOR 72V 3kW BLDC motor that goes to 4900RPM... and its pretty big in size! What would be the best way of figuring out whether that will or will not induce big enough voltage spikes to fry the controller?

un-commanded reverse pulse

Strange behaviour on my Trampa VESC 6 MKV.

I'm using PPM input with Duty Cycle control and when I am going forwards and brake suddenly (release the stick), it goes into reverse for about half a second.

If you look the data, the duty cycle ramps up to about 55% (in the opposite direction for which you were going).

Only happens in one direction e.g. if it happens when you are going forward and brake, then it doesn't happen when going in reverse.

Running at 12S (approx 50V), motor is a 6880 (16 mOhms).

Looking for any ideas on why this thing keeps just dying. Temp is fine, voltage is fine, it's registering duty cycle but not pushing anything to the motor. Issue areas in yellow. I can let it sit all day at full throttle after this and it will do nothing. Have to bring it back to neutral for ~5s, then it'll go again. Almost like it's rebooting, but I don't have any way to log this data other than the graphs.

FSESC 4.20 Tuning for RC ESC?

Submitted by Abcc123 on Thu, 2022-09-01 04:41

Hey everyone I need some help on how to tune my FSESC 4.20. I am doing a project with my son and we have to use 20v drill batteries, that cannot change. We are using an RC ESC right now and its flying, but when I go to the FSESC 4.20 it stutters really bad. I was able to tune it so well that it was snappy and responsive w/o load, but once a load is applied it bogs and says under voltage error. I changed A settings to motor/battery but the torque grunt was not there.

VESC 6 EDU: Motor Wizard - Detection failed

Submitted by Navigator_PJE on Mon, 2022-08-29 16:12

Hello,

We have got a problem getting our VESC 6 EDU running. The motor wizard of the VESC Tool terminates with a detection failed message:

Detection Result

Detection failed.

Reason: Flux linkage detection failed

Typing fault in the VESC terminal results in the following error code: FAULT_CODE_PHASE_FILTER

On the VESC 6 EDU a red LED is flashing.

Any ideas?

Are all VESC based ESCs within the same generation standardized in their sensors and data payloads?

Submitted by pearlgreymusic on Sat, 2022-08-27 11:43

Hi, I am working on a telemetry logging system for a combat robot.

I can't find information on most manufacturer's websites or product descriptions about if their ESCs have accelerometers inside of them.

I know that VESC compatible HW can have accelerometers on them, my question is if ALL HW4 and/or HW6 variants require accelerometers and other sensors, or if SOME include them and SOME do not.
