as the title suggests this vfd runs fine but puts out only about 75% of the proper voltage. To make things interesting he included manual is only in Chinese! Why do they even bother? There is a table of parameters and it shows units and default values and from that I managed to change the frequency to 60 from 50 and speed up the acceleration. So the thing does work. But I can’t imagine why it would put out such an odd voltage.
it is a zw g2 2t 3, whatever that means. It says on the case that it outputs 220v at 3 kw. Any idea what parameter could be changed? Any idea where I might find a manual?
Right now it is just hooked to a 600v 3phase doall vertical bandsaw but given that it shows 400v at the transformer output and 175v at the transformer input I don’t want to try turning on the saw. could the vfd be interacting with the transformer in a way that I don’t understand? I understand just the basics of electricity. Start talking about power factors and back emf and my eyes glaze over.
any advice appreciated
