Current turning capabilities status

I will try to find a 230V as it would be on the safe side. If I can't then I will thing in another possibility.
Thanks. Again.

I received a quote for a Mitsubishi

FR-F720-00770-NA

Less than 1800€. I must double check if it is flux-vector, but it seams that the work is not industry standard, so they may call it a different thing.
Thank you.

Just to update.
The Mitsubishi that I referred is not "fully suited" for vector flux control, only the A series. The price is also higher for the 15Kw motor and with a 1 month delivery time, so for peace of mind I ordered a smaller one (3.7Kw) to test on the motor before I buy the big one.
I hope that the smaller one is only not capable of delivering the full range of Amps and it would be enough to get the motor running and to tell me that it would be safe to buy the larger.

I've run large motors with small VFD's for no load testing, but found that the VFD needs to be tuned so that it won't alarm. I think I needed to lower the voltage to RPM map, but I'm not sure.

You can also lower the output voltage to run a 220 Volt motor from 440 Volt mains, but you may need to derate the VFD specs.

I doubt you will be able to get a VFD to run well enough for a C axis. Indexing for tool changing should be okay. My impression is that a separate motor and positioning system is geared or clutched in for C axis function.

I will keep the forum updated.
Both the VFD are for 220V, so not problem there. And both VFD are intended to work with an encoder. I have no personal experience using a VFD in closed loop, but lets see what it will turn out.
My first objective is to use the current motor, even without C axis.

This Saturday I was able to access the motor and clean it.
The motor indeed have an encoder attached, but the encoder is optical, working on a slotted disc. I can see from the electrical schematic that the encoder is 12VDC. This will not be suitable to the Mitsubishi drive that I bought, so I also ordered a TTL encoder with 2500ppr and index.
Accordingly to the Mitsubishi manual I must use a TTL encoder with ppr between 1000ppr and 4000ppr. I must also buy a separated card to the Mitsubishi where the encoder will be connected, so the total price is high.

While I am expecting the material (it will take a while to receive all) I have questions that are confused to me, and I could not found anyone that made this before:

1) If the VFD will receive the encoder signal how will linuxcnc know where the spindle is?
2) How will I control the spindle to make, lets say a movement of 5º?

Anyone made this before? Used a flux vector drive?
Thank you

Converting the 12V to TTL I think I could (simple voltage divider no?)

>>> How does the drive accept position information when it has encoder feedback?
I will get back to Mitsubishi dealer.

Andy: You are very friendly and helpful. Thank you.
