Hey good people
I see most of you are expert, hope I not offend anyone , but I am loosing my mind.....I am new
Quick story , bought 2 Fsesc 4.12 for Gokart project and new wheel's hub 800W 13S
On the bench I am use PWM controller, to do proper adjust , because in Gokart I will use my Arduino project with PWM output
So finally I am able to run both way my motor hub, but it always run full speed or stop
PWM mapping see proper movement of PWM signal , max , middle , min
Not a big different when I remove sensor , change FOC to BLDC not help
I was try to make speed up delay , or change speed curve , but range of low speed is very minimum, and after that motor speed up to max
is not smooth / fluent operation
Did a motor detection, also did a manual settings , not big different
who can help me ? not asking for free help of course .
Thx guys
If you are using Current control mode in the APP settings, then this is expected with no load. When you have it attached to the gocart it will behave correctly.
If you just want to control the speed, not the acceleration / torque output. Then use Duty cycle control mode in APP settings and it will work as you expect.
Hi
thank you for feedback
hmm.... In RC models , if not work on the ground, will not fly in sky ;)
I am old date guy who must test all first
asap I will try mount wheels and do drive test with fully load
Still discover more function in that ESC , and I am supprise of that , but some function should work stright away
t.b.c

Ok guys,
all seems to be sorted.
only one issue with PWM
I use 2 esc over Y cable
because in a futire i want to control independent both , but now - I use one output and Y cable
one ESC detect PWM little higher then other
mapping is fine , both can speed up maximum.
but when they slow down - one slow down faster , because PWM neutral is different than other one
Any idea how to fix it ?

Either the mapping is not exactly the same or there is some variability in the hardware between two controllers. You can try to compensate for that with slightly different mapping on one of the controllers.
