HEIDENHAIN Announces EnDat 3 Encoder Interface

So please consider turning off your ad blocker for our site.

Like all the versions of EnDat, the new EnDat 3 is bidirectional, so it can support monitoring and diagnostics. This means it can be used for preventive maintenance, for example, alerting the CNC when a fault is detected.

The new interface supports an increased number of temperature sensors to monitor temperatures anywhere, from a robotics arm to inside a cabinet. It has also added support for multidimensional encoders, which enables easier installation and simplifies the downstream calculation that’s involved with using multiple reader heads on a single cable.

Faster and more robust, with black channel support for functional safety

EnDat 3 uses a 200 kHz clock frequency, compared to the 16 kHz of previous versions, and has doubled its supported bandwidth, from 12.5 to a 25 Mb/s. This means that data can be transferred much more quickly.

HEIDENHAIN has simplified functional safety aspects of the interface, and EnDat 3 now leverages the industry standard for functional safety: black channel. This makes implementation much easier for OEMs.

Milton Willis, machine tool product specialist at HEIDENHAIN, says, “We’ve listened to feedback from machine tool manufacturers and their end users, as well as OEMs, and have responded by making EnDat 3 faster, more robust, and more fully featured than any competitive product.”
