[How do I?] Looking for advice on power requirement on a VFD for PM-1440GT and PM-949TV ?

[Golden Guns]

I have just purchased a PM-1440GT Lathe 3 phase and looking if anyone out there has ran a VFD on there lathe. I have also purchase a PM-949TV milling machine 3 phase and looking if anyone is running a VFD and if so What size Of VFDS? Any help would be great.

You might review some of the previous posts on this subject for both the 1440GT as well as the PM-935 and PM-949. Parts and programming for the Hitachi WJ200-022SF have been previously posted, but if there is some specific's or you are looking for something let me know. On the mill I have some simple designs, I usually include a tach and ring light housing. I believe a few people have also 3D printed holder for the ring light/tach sensor for the 935, but should not be difficult to adapt it to the PM-949. On the 1440GT many forum members have done what I call the basic VFD install which strips out the high voltage to the forward/reverse contactors and uses them for the low voltage inputs to the VFD. These designs are VFD specific, not interchangeable with other VFD's w/o modifications and different programming.

PM-1440GT Basic Wiring Changes for using the Contactors to switch the VFD inputs

I previously outlined the use of new contactors to use to switch the VFD inputs when doing a basic 3 phase VFD lathe conversion, this retains the same functions (and interlocks) as the stock lathe and should operate the same. The VFD adds speed control, and acceleration deceleration control. In...

PM 949 Rec'd and Waiting for Power

Finally received my PM 949 in late June (I had originally ordered the 935 primarily 'cause I thought space would be an issue but it really isn't) Thanks to some hints from Chevy about handling it with an engine hoist and a rented fork truck it went in to my shop relatively easily. . The...

PM-949TS VFD Full Build Control System with Auto Reverse and Back Gear Sensors

Normally I do not like to do full VFD build systems, they take way too much time and cost. But I was asked to do two full system builds one for a PM-949TS mill and an second for PM-1440GT lathe. I kinda of caved, figuring I hadn't done builds for either machine and I wanted to see what I could...

Received my PM949 and PM1340GT!!!

They are finally here!!!! :D I place an order with Matt for these two machines late December 2016 and finally had them delivered to me last Thursday. Their trip was long (Taiwan-->USA-->Trinidad and Tobago) but they arrived in perfect condition. The service I received from QMT was great. Matt...

PM 935TS ordered. Need guidance on VFD components and installation.

Ordered the 935TS with a 3 phase motor and need to get things ordered for the VFD installation. AC electrical is a definite weak point of mine so help is needed. I did the VFD install on my PM-1340GT a couple years ago with help from this forum and especially Mark Jacobs. That project went well...
