Configuration of the EIB 192

In order for the EIB 192 to operate correctlywith the encoder, certain encoder
parameters must be stored in the EIB 192(e.g., the number of signal periods, thenominal increment of the reference marks,
or the encoder ID). This programming canbe done only by HEIDENHAIN.

Line count or signal period
Important in the case of rotatory encoders
is the number of signal periods perrevolution, and in the case of linear
encoders, the signal period in micrometers.

Connection
information

Information about the EnDat interface

Establishing the absolute reference
After switch-on, the EIB 192 delivers
relative position values starting with theswitch-on position because the device isconnected to incremental encoders. Theabsolute reference is not established until
the reference marks have been traversed.

Requirements for the control
EnDat 2.2 continuously 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 you use the EIB 192,
please check whether the downstream
electronics support this EnDat 2.2 device
profile for incremental encoders.

Please note:
For encoders with distance-codedreference marks, two successive referencemarks must be traversed without a changein direction.

If the connected encoder has distancecoded reference marks, then the nominal
increment N of the reference marks
must be provided in signal periods.

Electronic ID labelWith the EnDat interface, the configuration
can be read out via the interface.

Please note:
It is not possible to combine the EIB 192
and interface electronics with the DRIVECLiQ interface (e.g., EIB 2391 S or
EIB 3391 S), because these interface
electronics accept only absolute encoders.
Online diagnostics
The EIB 192 supports the online
diagnostics of EnDat 2.2 and providesvaluation numbers for the incremental
track.

The encoder ID indicates the type ofencoder that can be connected (e.g.,EnDat22):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.
