Configuration of the EIB 1500

In order for the EIB 1500 to function correctly
together with the encoder, certain encoder
parameters must be stored in the EIB 1500
(such as the number of signal periods,nominal increment of the reference marks,encoder ID, etc.). Only HEIDENHAIN canprogram this information. This informationis also printed on the ID label. It can beread out via the EnDat interface.

The encoder ID indicates the type ofencoder that can be connected, e.g.
EnDat 22:80 	Rotational encoders without distancecoded reference marks
90 	Rotational encoders with distancecoded reference marks
For the EnDat interface, this value is stored
in word 14 of the EnDat 2.1 parameters.

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 nominal increment N of the reference marks is indicated in signal periods
if the connected encoder has distance-­coded reference marks (EnDat 2.2 encoder
ID = 90).

For rotatory encoders the number ofsignal periods per revolution is indicated.

ExampleConnection of two ERA scanning heads(line count 16 384) over EIB 1512 to theEnDat-2.2 interface.
Information on the ID label

Connection information
Establishing the absolute reference
The EIB 1500 must be connected only toincremental encoders with distance-codedreference marks. Immediately after switchon it provides relative position values thatbegin with the position upon switch-on.
The absolute reference is not establisheduntil the reference marks are traversed.
Both scanning heads have to move overtwo successive reference marks withoutchanging direction.

Product Information EIB 1500   9/2014

EIB 1512: Requirements for the control
EnDat 2.2 permanently provides the relative
position as Position 1. When the absolutereference is established, the RM bit is set
and the absolute position value is transmitted
in the EnDat additional data as Position 2.
Before you use the EIB 1512, please check
whether the subsequent electronics
support this EnDat 2.2 device profile forincremental encoders.
Please note:
It is not possible to combine the EIB 1512
and EIB 2391S, because the EIB 2391S
accepts only absolute encoders.

EIB 1512: Online diagnostics
The EIB 1512 supports the online diagnostics
of EnDat 2.2 and provides valuation numbers
for the incremental track, reference pulse
width and reference pulse position. In eachcase, the lower value of the two connectedencoders is applied. This provides informationon the functionality of the total system, but
it allows no direct analysis of a single
scanning head.
