It seems you have see the function 'Automatic restart' in action. I.e. armature supply voltage drops below treshold (P351) for the time not longer than P086. You may read about it in themanual, chapter 9.17. |

Hello. Ok, what type of drive you have? Simoreg DC-Master or Simoreg CM? When the drive stays in o4.0 for long time? Only after switch-on (ON command) or during operation? How long is this time? If this happen only after switch-on and takes not more than P089 (2 sec) - its normal. |

And you didn't get the fault F004 or F006? May you disable it in P820, please check this. I may recommend you to check the connections of gating pulses cables from board A7002 to the power section (X11-X16 and X21-X26). Or may be you can reset your drive to the factory settings (P051=21) and make a new comissioning. |
