Hello arshi; The screenshot below is based on the information from this document: https://inverterdrive.com/file/Siemens-Micromaster-Catalogue, p2-8 The MM420 has been discontinued for some time and Siemens has no catalgs available for these drives anymore. The information in this document is all I could find. Based on this limited data, a search on the Industry Mall has suggested these Sinamics V20 drives with similar configurations. https://mall.industry.siemens.com/mall/en/ca/Catalog/Producnts/10354448?tree=CatalogTree This Industry Mall link opens the Product Information section for V20 drives. What should be of interest to you are the paragraphs describiing the suggested applications for these drives, at the bottom of the page, you shoud verify that they correspond to the type of machine you need to control. You will find the suggested part numbers in the Ordering Data tab in the same link. I strongly suggest you validate any selection you decide on with a local Siemens rep (use the Contact & partners/Local partners link at the right of this page) before you proceed to a purchase. Hope this helps, |

Hello arshi; I do not feel at ease suggesting successor models for synchronous motors, there are oo many parameters to choose from. I propose you start by looking at the following document detailing the breakdown of 1FK7 2nd generation servo motors; use the information provided to start building the approximate part number your need for your replacement motor.: https://support.industry.siemens.com/cs/ww/en/view/55738520 Once you have determined the main model part number for the 1FK7 servo motors you need, compare them with the model entries for 1FK7 motors on section 8 of this Simotics catalog (starting at page 8/32) and select a complete part number for your replacement motors. Once you are confident you have selected the correct model for your application , confirm your selection with your local Siemens rep before moving to purchase. Hope this helps, |
