Description

Absolute encoders deliver an absolute step value

for each angle setting. All these values are

represented by code samples on one or more code

disks which are sampled by a photoelectric array.

The absolute encoder has a maximum basic

resolution of 65536 steps per revolution (16 Bits). In

the multiturn design, additional up to

16384 revolutions (14 Bits) can be resolved. This

results in a total maximum resolution of

1073741824 steps (30 Bits).

The encoders integrated CAN bus interface

supports all CANopen functions. The following

operating modes can be programmed, and can be

selectively turned on or off:

•

Polled mode

•Cyclic mode

•Sync mode

The device is designed for shaft assembly and is

available in servo flange or clamping flange design.

The bus electronics module is integrated into the

removable housing cover. This makes it possible to

mount or replace the encoder and the bus

electronics separately during installation or service.
