The ND 200 series DROs hosts multiple inputs, is flexible in its configuration, is suitable for future absolute length gages and features comprehensive functions. The new single-axis DROs come in two variants—the ND 280 featuring standard functions to fulfill many measuring tasks and the ND 287, which is modular in design and allows up to four inputs. This feature allows toggling between multiple gages, sensors and encoders to be done easily.

 

Within the ND 287, three additional axis modules are incorporated. Two of them are analog, which permit the connection of analog sensors, and purely serial EnDat 2.2 units that allow for the connection and full use of absolute encoders. Also, this DRO can be integrated into the Ethernet facilitating remote monitoring.

 

Statistical Process Control is now also available on the company’s ND 287, allowing the ability to write as many as 10,000 measured values to an internal memory and evaluate them statistically.

 

The ND 280 and ND 287 both come equipped with a card for gage hookup and are an improvement from past Heidenhain single-axis DROs as they sport new features. Among these are the ability to design functional equations to manage interconnected operations of multiple axes and soft keys, which provide many benefits with regard to operation and parameter setting. These units can display both linear and angle/rotary encoders, as well as reading distance-coded reference marks. Encoders with EnDat 2.2 can be connected to both.
