Hello. Rated armature voltage of motor is set via P101, also check all start-up procedure (including optimization runs) in the manual, chapter 7.5. |

Did you make speed controller optimization (P051=26) after P051=25? |

May be you need to make manual optimization of speed controller to remove fluctuations. 3. Did you check P115? 4. By default in 6RA70 P082=2 (standstill field after line contactor drop). Check the value of P257 or use P082=1 or 3. |

check the actual Field Resistance after removing motor terminals using meter. |
