Looking to run some alpha amplifier modules from straight DC - Can anyone confirm this will work?

I have an LR Mate 200iB (A05B-1138-B201) with no controller.

I've found an R-J3iB controller (A05B-2442-B160) for it.

The controller contains the amplifier modules A06b-6114-H302. These are designed to run off of the rectified DC from a three phase supply. I do not have three phase where this robot is going to be installed, only single phase 220 (30A).

I understand rectified single phase is nowhere near clean enough and will throw errors, possibly burn out parts.

I have a dc supply capable of delivering the required 283-339V DC the amplifiers want. Specifically I was hoping to use AIF04ZPFC-01L modules, which can be turned down to a healthy 311V.

Two questions:

1. Is this robot compatible with this controller?

2. Will I have to trick it into thinking 3 phase supply is available, or will it just accept that there's perfect DC at the units? Is there any reason pure DC wouldn't work?

Thank you all, this is a wonderful community.

This is the same controller

There's some good pictures of it inside.

The beta modules are like that, but everything I have ever read about the alpha servo amplifiers says it won't run on single phase. Only the control components are capable of that.

I believe you are referring to the power supply for the controls equipment, which is indeed single phase. This isn't connected to the motor amplifiers.

The motor connector isn't CX1A, but the L1, L2, and L3 pins at the bottom of the card (much heavier screw terminals, under the gray cover)
