PITMIX said:@John61ct, Yes he's doing FOC.
@Andrewrich On PID regulator, You can decrease the KPi setting to 100.
Did you set the number of poles correctly ?
Did you do the last update?

PITMIX said:Look at the version you have, the latest update is V.7.18 for the controller parameters and v 0.60B for the display. Updates are not mandatory, but they are so good that it can improve the functioning of your engine. setting of Dci ki important in FW mode. http://nucularelectronics.wikidot.com/en:firmware

PITMIX said:The number of poles is important to display the speed as a function of the engine rpm. It is also necessary to adjust the transmission ratio in the case of a mid drive engine. But if it is a Hub motor then the number of poles is sufficient.
It's the integral constant in the PID loop. If it is set too high, it can cause oscillations.DanGT86 said:Im having a similar stuttering issue with the small LMX motor which is similar to a cyclone. I'll check my DCi Ki setting.
Can anyone explain what that is?
When changing it from 500 to 100, is there some significance to the value of 100 or is decreasing incrementally until the stutter is gone a better idea than blindly picking 100?
DanGT86 said:I was just hoping to understand what it was since integral constant in PID loop doesn't mean anything to me at this point.
I did try changing it to 100 it was at 200 as shipped from Vasiliy. The motor is still stuttering really bad at full unloaded RPM in FOC mode. I did notice there was an FOC Ki in that menu. Its set to 130. I wonder if that has something to do with it. I'll ask on the telegram chat if he hasn't checked in on either thread soon. I don't really have time to go road test at the moment anyway.
