Variable Frequency Drive (VFD) for a Commercial Convection Oven

KB Electronics, Inc. Manufacturer of AC Drives, DC Drives & Variable Speed Controls

 

Application:

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.

KB Solution:

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.
