Hello kakil; Yes you can use the MM440 as a single-phase drive. Look at the considerations from this document:
Siemens Micromaster 440 Quick Start Guide: files.ua.prom.st/315722_siemens_microm__tart_guide.pdf IMPORTANT NOTICE: Operation with 1-ph 230V AC line With the SW 2.08 and higher it is possible to supply the inverter 3 AC 200 V- 240V also by an single-phase 230V line. The following restrictions have to be considered: - The devices can only operate with maximum 50% of the rated output current (VT). - The resulting output current is also possible in CT-operation. - An overload capability is not possible in both duty types. - In both of these cases, there is no longer an overload capability available. If the output current exceeds this limit, the drive unit shuts down,depending on the magnitude of the output current, in seconds with Fault "F0020" (phase failure). When utilizing the 50 % limit of the VT output current, the following input voltage range should be maintained: For Frame Sizes D and E: 230 V +15% -5% For Frame Size F: 230 V +15% -10% And the connections diagrams attached below are taken from the following manual: MM440 operating instructions: https://support.industry.siemens.com/cs/ww/en/view/24294529 If you plan on using a single-phase motor look at this FAQ: 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
