    Default Hitachi Seiki TF15

    Hi Folks,

    I have Hitachi Seiki TF15 with 2 alarms on the screen:

    906 PCU Circuit protector in the 3rd axis is in OFF position,
    890 Regenerative Resistor in the 3rd axis overheated,

    I followed schematic in maintenance manual and cannot see a standalone unit identified as PCU. All units/ drives seems to be NEC ADU.

    I noticed the black plastic switch under spindle drive unit was OFF. When moved to ON position I got 802 alarm.

    Not sure where to go next? I have attached solutions as per manual.

    Hopefully someone can put me in a right direction
