Re: Question for Russ and other VFD ninja's

So it seems like sensorless vector conrtol is somewhere in the mid range of what VFD's can do? If thats right i'm quite pleased as it was the same price as Huan Yang's but does seem to be better - it having programmable outputs/inputs etc. Now onto getting my head around the braking resistor :?: :?:...

Page 24 of the manual does say it's there. Might try it later - see what happens :? Whats the worst that can happen?
Do you guys doubt because it's Chinese?

Re: Harrison m300 with acorn centroid control

I just need to know what to buy really size/type etc? The motor is 2.2Kw 3phase uk so its 230/240 volt. Manual is included here for VFD. Thanks an...

Re: Acorn Advanced Homing sequence to marker pulse
