First Angle Encoders with Mechanical Fault Exclusion on the Market
HEIDENHAIN CORPORATION is pleased to announce the first and only angle encoders on the market to have a Fault Exclusion for Loosening of the Mechanical Connection. This is a primary prerequisite for encoders meeting Functional Safety standards required for any machines shipped to Europe.
Safety-related position measuring systems
HEIDENHAIN offers encoders that can be used in safety-related applications. These encoders operate as single-encoder systems with purely serial data transmission via EnDat 2.2. Reliable transmission of the position is based on two independently generated absolute position values and on error bits. These are then provided to the safe control.
Minimize Risks During Normal Or Impaired Machine Or Facilities Operation
The goal of functional safety is to minimize or even eliminate risks that can occur during normal or impaired operation of machines or facilities. HEIDENHAIN offers a purely serial, single encoder solution for safety-related position measuring systems in safety-oriented applications in accordance with EN 61 508 and EN 13 849. This means that safety applications can now take advantage of all the benefits of serial data transfer, such as optimization of costs, diagnostic possibilities, automatic commissioning and rapid formation of the position value.
Safety-Related Control Technology for Machine Tools
Safety is becoming increasingly important in machine and plant construction. These high requirements mainly serve to protect human beings, but material assets and the environment are also receiving more consideration. The goal of functional safety is to minimize or even eliminate risks that can occur during normal or impaired operation of machines or facilities. This is achieved primarily with redundant systems. For example, axes that are moved in safety-oriented applications require redundant position information and dual-channel safety systems in order to perform the corresponding safety functions.
EnDat 2.2 – Bidirectional Interface for Position Encoders
Digital drive systems and feedback loops with position encoders for measured value acquisition require fast data transfer with high transmission reliability from the encoders. Further data, such as drive-specific parameters, compensation tables, etc. must also be made available. For high system reliability, the encoders must be integrated in routines for error detection and have diagnostic capabilities.
