All,
Now that the lathe has a new bench, it's getting converted to 3 phase VFD before final positioning and leveling. The VFD is the ever-popular Huanyang 1.5kW VFD shown here: http://www.ebay.com/itm/BRAND-NEW-2...272?pt=LH_DefaultDomain_0&hash=item2c69b9a1c0
Here's the correct motor for the lathe matched to the power of the VFD: http://www.globalindustrial.com/p/m...ors/iec-metric-motor-90l-ip55-3ph-c90t17fz2cc EDIT: BTW, the motor is wireable for 2 speed but that's ignored for our purposes.
Last night, I programmed the VFD and tested an external pot and signal lines on a bench setup. As soon as I double check registers and test thoroughly, I'll post the settings here.
Also, here's how I'll probably rewire the control aspect of the unit. View attachment 1236 VFD Control Wiring.pdf
I might tweak this a little so, hang-on until I'm done being the guinea pig. I'm not sure if the native switches are normally open or close and I'll try to reuse as many as possible. The FWD and REV switches on the lathe are mechanically mutually exclusive. The JOG button is not so I'll need to see how the VFD reacts if JOG is asserted while either FWD or REV is active. ... thus, I may need to tweak things a tiny bit. Here's a quick sketch -about as simple as it gets...
