DMG 50T TNC426/430 Error C3B0

[Ozcad]

Hi All

I have a Deckel Maho dmg 50t year 2000 running a Heidenhain TNC 426 control. On start up without trying to move any of the Axis the power on Y Axis goes high and I get a C3B0 Error.
I have had a Heidenhain tech look at it who found there seemed to be current leakage to earth in the cables so I replaced these with genuine cables but the Error still comes up .
I removed the Inverter and had it tested by the tech on his bench, it appears fine.
Any help with this issue would be appreciated

Regards
Nick
