Installing a variable speed drive allows direct control of the motor output speed to meet the application demands. As the speed is reduced, the power required decreases. By operating the system at the lowest possible speed required for the application, energy consumption is reduced. For example, at 80 percent speed, only 51 percent of full load power is required to drive a pump or a fan.
A convection oven utilizes a stirring fan to circulate heated air which substantially reduces cooking time. The customer was purchasing an expensive drive manufactured in Europe which they desired to replace with a low cost drive manufactured in the USA.
In the application, the drive receives serial communication commands from a PLC that provides the user with various cooking recipes. A standard drive could not be used because the communication protocol, although similar to Modbus, was unique and proprietary.
The low cost KBVF Series VFD, with the DIDF Serial Communications Module, was chosen for this application. KB engineers were able to decode the proprietary serial communications protocol and reprogram the standard DIDF Communications Module.
The result was exactly what the customer desired-a low cost VFD assembled in the USA with proprietary serial communications.
