Need Help! Error SV5136 & SP1220 & not activated MCC

[liqvidator]

Hello.
I have a problem with 3rd axial milling center on Fanuc 0i-Mate-MD. I see two troubles after machine power on:
SP1220 (S)
SV5136 FSSB: Current is insufficient
Also servo amplifier A06B-6164-H343#H580 indicated the ALM status lights up after power on CNC-controller.
And doesn't come to the coil of the main electromagnetic actuator 110V (MCC).
I check the voltage between phases tension 223V, and concerning grounding 150V, 136V, 114V.
What need I do now for checking and repair machine?

did you measure voltage between all phases R-S S-T R-T?

Yes. 223V between all phases after transformer, but between phase and ground other voltage: 150V, 136V, 114V.

what's on the drive's led display inside the control cabinet?

what's on the drive's led display inside the control cabinet?

Yesterday I made a replacement management card for verification. I removed the board A20B-2101-0711 / 06DR and supplied the A20B-2101-0711 / 02AR. The machine worked stably for 1 hour.
Then I changed the boards again. The system started up and booted and worked for 3 minutes. Then again, the indication greed & red on the servo amplifier and the error on the display SYS_ALM_120 FSSB DISCONNECTION MAIN.

I would change all electrolitic capacitiors on PCBs. at least in servo drives

I have a problem i feel is in the same area of the servo amplifiers, MCC, and emergency stop that is tied into this circuit

I have a 1985 Amada OCTO 334 with Fanuc System 6M Series M31 Version 03 controller. Monday morning came to turn the machine on and it has a external alarm 14: Emergency/Reset. Did some testing in the area of it being a problem with the EMG switch or circuit( tested relays, changed switched etc .) I was suggested by amada service in CA to jump 205 with any common 200.(205=*WEM emergency stop switch) when i did this the machine no longer had code 14, but then a code 401 Servo.: The ready signal (VRDY) for velocity control of X-,Y-,or T-axis is off.

So from what i have learned so far is that , the code 14 is a builders alarm , based off a initial system check , NC is not ready . My guess something to do with the servo's since when i jump 205 it then gives me 401 alarm. So i started with basics. i cleaned the brushes and cleaned out the dust. then topped off the fluid.
a bit more information.
The servo amplifiers(and if i have this correctly are also the velocity control unit ) have two led green lights. on the boards it says RDY with a small v slightly above it but could possibly belong to something else on the board, and the other light has PRDY(positional control). . Only the RDY light is lit on all X-,Y-,Z(T)and C the auto-index.

Behind all these PCB is several components like two breakers,terminal boards,MCC, thermal relay etc. the magnetic contactor is supposed to send the signal to the servos and then recieve a ready signal back, right? Well it looks like these MCC's don't suck the center tab in like a much bigger magnetic contactor on the input signal board does when i turn on the power . Wonder if that is telling me anything or if they aren't activating because the problem could be before the signal even gets that far .

Help would be greatly appreciated
Thanks

SV 5136 is number of AMPLIFIERS is small. The amps reporting to the control and the FSSB settings dont match. Lots of times the fiber optic cable is broken from COP10B - COP10A.

I second 'freakycnc' comment. Check fiber cables first.
Plus its easier than the capacitors on the first pass unless you already have it opened up.

the same problem if any one can help

That seems that the Spindle Amplifier isn't working.
