Haas Next Generation and Classic Controls 111
Haas Next Generation and Classic Controls compares the two versions of control panels from Haas Automation®, Inc. While the two control panels look and function similarly, some key differences separate the Next Generation Control (NGC) and Classic Haas Control (CHC). Operators switching between using CHC and NGC machines must adjust to differences in hardware and software as well as changes to the control keypad and display screen. Additionally, the NGC uses updated cybersecurity features with which operators must familiarize themselves.
In order to successfully navigate the operational nuances of the CHC and NGC, it is vital for operators to develop a comprehensive understanding of the differences between the two control panels. After taking this class, users will be able to distinguish between many of the distinct features of the CHC and NGC.
