Motor moves jerky

Hello,

 

I am using a remote control to regulate the output adc value and the motor seems to have a jerky start and later at the higher voltage it starts running smoothly. Can someone tell me how to fix this issue?

You didn't mention anything about your hardware or your configuration, what position sensors you use, etc. In senseless mode, a jerky start would be expected but there is no way to tell what's going without knowing you are running.

Hi there, I am using the VESC 6mkv and and have connected a led dimmer circuit connected to the ADC. the way i am trying to use is the outut of the led dimmer goes into the adc value and the input to the dimmer is VCC from the vesc. when I vary the output voltage of the dimmer using a remote. the motor seems to have a jerky movement at lower speeds. but at higher or max volatge the motor speed is constant.
