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.

The connected host requests the current actual position value via a remote transmission request telegram. The absolute
encoder reads in the current position, calculates all parameters that have been set and sends back the process actual
value through the same CAN identifier.
The absolute encoder sends the current actual process value cyclically, without being prompted by the host. The cycle
time can be programmed in milliseconds for values between 1 ms and 65536 ms.
After the sync telegram has been received by the host, the absolute encoder sends the current actual process value. If
multiple nodes should respond to the sync telegram, the individual nodes report one after the other according to their
CAN identifier. There is no programming of an offset time. The sync counter can be programmed so that the rotary
encoder does not transmit until after a defined number of sync telegrams.
The direction of rotation (complement) can be specified by parameter as the operating parameter. This
parameter determines the direction of rotation in which the output code will ascend or descend.
The "Resolution" parameter is used to program the rotary encoder so that a desired number of steps can be
implemented in reference to one revolution.
This parameter indicates the desired number of measurement units of the entire travel length. This value must
not exceed the overall resolution of the absolute encoder.
The preset value is the desired position value that must be achieved for a specific physical setting of the axis.
The preset value parameter is used to set the actual position value to the desired actual process value.
A total of two positions can be programmed. The absolute encoder sets one bit to high state in the 32 Bit
actual process value if a value falls outside the range between these two positions.
Up to 8 position values can be programmed as cams. By reaching these values bits in object 6300h Cam state
register are set.
