By doing so, the programmer is able to create advanced motion routines in addition to the simple start and stop features.

However, a much more practical approach is to add the drive to a private network which includes a Programmable Logic Controller. These drives can be easily wired to start and stop from push buttons through direct inputs. Their reliability as well as ease of use, especially within the Rockwell Automation ecosystem, has allowed them to become popular all over the world.Ĭomissioning a PowerFlex 525 VFD is straightforward. The PowerFlex 525 series of Variable Frequency Drives from Allen Bradley are an excellent choice & have been an industry standard for several years. VFDs are flexible, provide additional control and data in every application. Based on this phenomenon, it’s now recommended to utilize a VFD over a contactor in every application. Over the last decade, these devices have become increasingly cheaper. Variable Frequency Drives are used within the automation industry to drive induction motors with added precision over a simple contactor.
