Re. 6SE6440-2AB23-0CA1 Can this unit work with a 1 phase (240VAC) supply ? |

Hello Haggis; Normally, theMM4 (and Sinamics) drives are designed for motors that run minimum 3-phase 240V AC; but under certain confditions (and parameters) they will run with single phase power. After all, Siemens provides demo cases for training purposes that integrate small MM4 or Sinamics drives with motors that will operate on single phase 230 V/50 Hz or 120 V/60 Hz. See this presentation for example: https://support.industry.siemens.com/cs/ww/en/view/109772205
- MICROMASTER 4 (MM4), SINAMICS V20 , SINAMICS G120 (CU2x0x): Operating single-phase motors. https://support.industry.siemens.com/cs/ww/en/view/12519917 Hope this helps, Daniel Chartier |

For clarity then..... one just connects Live to the L1 input, Neutral to L2 and the unit will at least power up ? |

Hi, if it is Your intention to drive any kind of load, then You have no chance. I read your question as only wanting to retrieve parameters. I'm afraid You are stuck here, any amount of firmware flashing isn't going to help, and as the unit is a single block - frame size C, then it would require a complete new unit. If that is Your course of action, then You would be better off upgrading to a Sinamics V20 or G120 as the Micromaster is practically obsolete - See the SIOS page HERE Regards, Graeme |
