Communication protocol added to encoders

Heidenhain offers the use of Siemens Drive-CLiQ communication protocol in its ECN/EQN 1300 optical absolute encoders.

The Ethernet-based protocol interfaces with Sinamics control systems. It has a speed of 100 Mbit/sec. and a cycle time of 31.25 μs. Motion control system components with the protocol are configured automatically with each other, since every component has an electronic label.

Both the single-turn and rotary encoders have 24 bits of resolution. Part of the company’s Functional Safety encoder line, they qualify for SIL 2 designation according to EN 61508 and Category 3 PL d according to EN ISO 13849-1:2008.
