  • Control unit for multiple variable frequency drives
    Patent number: 11391486
    Abstract: A control unit is communicatively coupled to multiple variable frequency drives. The control unit includes a controller, and each variable frequency drive may have a respective controller. The controller of the control unit may be communicatively coupled to each variable frequency drive controller and manage and/or configure the multiple variable frequency drives by sending instructions and/or receiving information from the variable frequency drive controllers. In some embodiments, the control unit may be implemented as a part of a mobile computing device, such that the controller may wirelessly and communicatively couple to each variable frequency drive controller. In this manner, managing or changing settings and/or control parameters of multiple variable frequency drives may be performed via a single control unit, avoiding the tedious, repetitive, and inefficient process of using multiple control units.
