A variable frequency drive (VFD) is a critical component in motion control applications, providing a motor or load with a high level of speed control and diagnostics that an across-the-line motor starter or soft starter is unable to. The below flowchart, developed by AWC automation engineers and subject matter experts, can be used to easily identify the best Siemens VFD family for a particular application. Note: all rated HP values listed are based on Low Overload (Variable Torque applications)
The below table below provides an overview of each of Siemens’ SINAMICS VFD families included in AWC’s Design Assurance program. Please note that the attributes shown in the table are what are included within the scope of the Design Assurance program, not the complete range of the products.
