    Wrong Voltage whoops....

    OK I'm an idiot, I was doing some rewiring and I accidentally wired 120v with 240v and it blew a variristor. So I replaced the variristor and wired it properly but now the servo drives won't power up. Is there something I am missing it seems like everything else in the panel is fine.
    Any input would be greatly appreciated.
    Thanks Mike

    Check the parts with a meter, starting with the power circuits: fuse, diode bridge, output transistors. Measure the voltage on the big capacitors (very carefully). If everything is fine there, check the low voltage power supply.
