It is pretty much the same as the PM-1440GT (it is the same manufacturer, the specs are vendor specific). I would go with the basic VHD 1440GT wiring directions posted previously. The directions are based on using the WJ200-022SF VFD, it can be purchased from Eisen or https://www.driveswarehouse.com/ . You will need a braking resistor, this and VFD enclosure suggestions are in the attached document, availability my be different in Canada. This is a general guidance as well as the suggestions for the basic VHD1440GT wiring directions. If you are unsure on any of the electrical's, get an electrician to check your work. Also in Canada, there are different code requirements, if I recall they require a power disconnect at the machine/VFD enclosure along with proper fusing.
I am constantly tweaking the VFD parameter files, when you get ready to program the VFD, send me a PM and I will send the current iteration for the WJ200.
Be aware that when rewiring the lathe with a VFD, the motor must be directly connected to the VFD, contactors are not used. The VFD motor output will sense overload/short conditions. The VFD input power should be fused along with a power disconnect. You need to provide 240VAC power to the lathe control box for the transformer power and for the coolant pump, but you could reduce the size of the control box fuses since they are no longer supplying power to the motor via the contactors. Single phase power to the lathe control board for the transformer per your schematic would be connected to terminals R and S which go on to connect power to the transformer. On the coolant pump power would be supplied through the contactor, you would need to see which terminals the overload relay is connected to and which coolant motor wires are connected (should be R and S).
You need a dual pole brake switch to replace the stock one, so when depressed it breaks power to the contactors and the other pole issues a free run command to the VFD. Otherwise the VFD will fight the foot brake when applied.
This all assumes you have some basic familiarity with electrical wiring and know what you are doing.
This is the PM-1440GT control board, you can see it is the same, the earlier models had a cartridge fuse holder.
