installed a 220 mono on a 3phase 220 motor (1.8 hp ) with a vfd (2.2 KW) it is a 2 speed engine .
when i connect it to the low speed it pick up to 50 hz (euro) with no problem
when i conect it to the high rpm side ofthe motor it work great in 1-2 gear but 3th gear it takes 2x the time to go to 50 hz
and in 4TH gear it takes nearly 30 sec to reach 50 hz.
is the (cheap ) vfd to weak ? some where a rong setting ?
max engine A is 5.4 and i a got the A setting to 6A
ramp time is set 1.5-2.5-3.5-4.5 sec
it is thise VFD
