Conformal-Coated Control Boards

Optional features, such as conformal-coated drive control boards, are becoming standard—protecting equipment from dust, corrosion and other environmental conditions. This clear material is applied directly over the electronic circuitry of the control boards and can greatly extend drive life.

Onboard Communication

Onboard communication—which enables communication between the drive and other devices within the system and reduces the software configuration setup time—is also quickly becoming standard in modern VFDs.
Ethernet IP, Modbus transmission control protocol (TCP)/remote terminal unit (RTU) and building automation and control network (BACnet) are becoming the default communication protocols included in industrial VFD products.
These communication protocols reduce wiring time when compared to traditional input/output designs and also provide more control and monitoring capabilities. The pre-programmed firmware is configured for ease of setup and the ability to easily interface with other manufacturer’s components and programmable logic controllers.

Conclusion

A proven technology, the modern capabilities of VFDs are redefining motor control. VFD technology available today continues to generate more economic and flexible motor control solutions which can result in less expensive electric bills and more reliable operations. Additionally, these solutions are engineered with the end user in mind to make system installation, setup and commissioning easier and more cost-effective.
