    Freqrol FR-Z200-UL (Meldes M320LC-V - Cincom E25JII)

    Hi all.
    I have Cincom E25JII, with Meldas M320LC-V controller. It has 2 tool turrets and both have live tools.
    My problem is when I want to put rotation on the live tools I get the following alarm on the Freqrol Z200-UL inverters: EOVT: Braking regenerative power from motor exceeded the regeneraive overvoltage limit.
    On one of the turrets I sometimes get rotation, and sometimes the error, on the second turret I have never been able to get rotation of the live tools.

    Any able to explain to me what the problem could be?

    Thanks!!

    Did I ask this question in the wrong section, or can no one help?

    Looks like something may be wrong with the inverter. These are quite old units and Mits does not even repair them anymore. You can upgrade to a replacement unit from Mits.

    Transistor on one of the boards (the bottom one) of this inverted went bad. Your best option is to find a used or new of a newer style - A520 series.
