Configuration of the EIB 3001

In order for the EIB 3001 to operatecorrectly with the encoder, certain encoder
parameters must be stored in the EIB 3001
(e.g., the number of signal periods, nominal
increment of the reference marks, encoder
ID). This programming can be done only by
HEIDENHAIN. This information is also
printed on the ID label and can be read via
the EnDat interface.
Information on the ID label
The data interface designates the type ofinterface for transmission of the position
values at the output of the EIB.

The Encoder ID states the type ofconnectable encoder. For example, in thecase of EnDat:00 	Incremental linear encoder without
distance-coded reference marks
10 	Incremental linear encoder withdistance-coded reference marks
80 	Incremental rotary or angle encoder
without distance-coded referencemarks90 	Incremental rotary or angle encoderwith distance-coded reference marks
For the EnDat interface, this value is stored
in word 14 of the EnDat 2.1 parameters.

Line count or signal period
For rotatory encoders, the signal period isexpressed in the number of signal periods
per revolution. For linear encoders, thesignal period is shown in µm.

Line count orsignal period
Data interface

The nominal increment N of thereference marks is indicated in signal
periods if the connected encoder has
distance-coded reference marks (EnDat 2.2
encoder ID = 10 or 90)
Example:Information on the ID label for the connection of an ERM 280 (line count: 1024) tothe EnDat 2.2 interface via an EIB 3001:
Data interface: EnDat22
Encoder ID: 80

Connection information
Finding the absolute reference
Because incremental encoders areconnected to the EIB 3001, the device
provides relative position values
immediately upon switch-on, starting withthe switch-on position. The absolutereference is not established until thereference marks are traversed.
For encoders with distance-codedreference marks, two successive referencemarks must be traversed without a changein direction.

EIB 3001: requirements for the control
EnDat 2.2 permanently provides therelative position as Position 1. When theabsolute reference is found, the RM bit isset in the EnDat additional data, and theabsolute position value is transmitted asPosition 2. Before using the EIB 3001,
please check whether the subsequent
electronics support this EnDat 2.2 device
profile for incremental encoders.
Please note:
It is not possible to combine the EIB 3011
and interface electronics with the DRIVECLiQ interface (e.g., EIB 2391 S orEIB 3392 S), because these interface
electronics accept only absolute encoders.

EIB 3001: encoder mounting and online
diagnostics
The encoder is mounted with the help of
the testing and inspection devices fromHEIDENHAIN, but not with the EIB 3001.
After the encoder has been mounted, it
can be connected to the EIB 3001 and thedownstream electronics.
For checking encoder functionality, theEIB 3001 supports online diagnostics byoutputting valuation numbers for theincremental track and a valuation numberfor the sum evaluation of the reference
pulse. This allows the function reserve of
the connected encoder to be evaluated.
