Hello, The vector control dose not work below ~ 3-4Hz, below that frequency the inverter switches automatically to V/f-characteristic. Maybe you need a boost - P1310 - to have more power between 0 – 5 Hz http://support.automation.siemens.com/WW/view/de/26483328 http://support.automation.siemens.com/WW/view/en/22095333 |

Sorry I didn´t get this point. What do you parametrized in P1300? It should be 21 (may be 23) There is a number of posibilitys / parameters descirbed in P1300 to adjust the closed loop control well, pls have a look into it. http://support.automation.siemens.com/WW/view/en/23708204 |

Found the problem, The drive was set to skip frequency of 0Hz but with a 2Hz hysterisis so would not work from 0-2 Hz |
