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 absolute encoder is mounted directly onto the
application shaft, without any coupling. Rotation of
the encoder is prevented by a torque rest. 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.
