Hello Vial, There are a few ways to accomplish your task of specifying inverters by amps; however, the basics are as follows. Select an inverter which has base load current matching the full load amps of the motor that will be controlled. The inverter must be then able to support overload of 150% of the full load amps of the motor for 60 seconds every 300 seconds for load cycle period. By definition of the SINAMICS S120 drives base load current IH allows for an 150% overload current for 60 seconds every 300 seconds for load cycle period. See attachment from Siemens PM 21 2013 Selection Catalog. As a tool, you could use SIZER for Siemens Drives tool and specify a load current matching the full load amps of motorwith an150% overload current for 60 seconds every 300 seconds for load cycle period. https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objid=10804987&nodeid0=10804987&DataKey=10804987&treeLang=en&lang=en&extranet=standard&viewreg=WW&u=NDAwMDAxNwAA&siteID=cseus PRODIS Entry:
