VFD Control Panel

The appearance of varying speed in a process may be straightforward when viewed on a computer screen; however, within a control cabinet, the quality of power, heat dissipation, harmonics, and cable arrangement are the criteria for whether or not the drive will operate as designed or cause a shutdown. Perfect Automation & Innovation manufactures VFD Control Panels with this reality of the field in mind; the end result is to provide stable control of a motor over the course of changing loads and not simply to contain a drive.

The structure of the control panel is designed with airflow pattern, separation of power/control, and provision for proper grounding continuity. Input protectors, line reactors, DC chokes, harmonic filters, braking units, and output reactors are selected based on the application of duty (pumps, HVAC, conveyors, compressors and very high inertia) to prevent nuisance tripping, therefore extending the life of the motor.

The arrangement of the wiring within the control panel is designed to allow for easy access for service technicians to trace signals quickly during commissioning or troubleshooting. Parameter access, bypass circuitry, and local/remote operation logic are set up based on the actual operation of the plant, not merely to meet the specifications of the demonstration. Connection to PLCs and Building Management Systems is clean and expandable.

Every VFD Control Panel is load tested, insulated checked, and functionally tested prior to shipment; the ultimate end result is to have a VFD Control Panel that will provide controlled ramp up, measurable savings in energy consumption, reduction in mechanical forces, and continuous performance of the process for the most demanding industrial and commercial applications.
