    Default Need Help! Error SV5136 & SP1220 & not activated MCC

    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.

    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.Need Help! Error SV5136 & SP1220 & not activated MCC-img_1364-jpg
