Encoder: Absolute position measurement with scale tape linear design

Heidenhain LIC 4000 encoder provides high traverse speed and absolute position measurement at a resolution of 1 nanometer.


Heidenhain introduces its new LIC 4000 encoder, which applies absolute position measurement technology to a multi-substrate scale tape linear encoder design. According to the company, its specialized scanning technologies are “insensitive to contamination and therefore guarantee a high degree of equipment availability and a high traverse speed, while at the same time achieving a high resolution of 1 nanometer.”

Heidenhain LIC 4000 encoder applies absolute position measurement technology to a multi-substrate scale tape linear encoder design.

Absolute encoders, which provide the current position immediately upon switch-on, offer high technological reliability and safety because they can operate without the reference runs that would otherwise be necessary. Absolute encoders also are especially well suited for use on direct drives.
Together with the current position, the commutation offset is known immediately upon switch-on and the motor can immediately be provided with power and held in the control loop. Critical operating states, such as switching on a vertical axis with direct drive or retraction after an emergency stop, are controlled safely.
These encoders feature up to 27 meters of measuring length and use the fast, purely serial EnDat 2.2 interface. Their dimensions match those of Heidenhain’s existing Lida 400 incremental linear encoder. This makes it easy to retrofit existing machine tools, providing absolute measurement technology by just exchanging the encoders. Only the subsequent electronics must be adapted correspondingly.
Heidenhain’s exposed linear encoders also feature customer-friendly mounting tolerances, high traversing velocity, and low height of the scanning head. More information is available via e-mail .

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
