Description

Absolute rotary encoders deliver an absolute

step value for each angle setting.

On account of the high number of measuring

steps, this type of absolute rotary encoder can

be used to divide very long linear distances into

small measuring steps.

The Ethernet interface of this absolute encoder

supports the Powerlink V2 protocol. An integra-

ted hub allows wiring in a line structure (daisy

chain). In addition to various functions like reso-

lution adjustment, rotation direction, node num-

ber setting or limit switch adjustment, the

following operation modes can be selected:

•

Polled mode

•

Multiplexed mode

•

Poll response chaining

The device is mounted directly onto the applica-

tion shaft, without any coupling. Rotation of the

absolute encoder is prevented by a torque rest.
