EIB 3391Y
Interface Electronics
as Cable VersionApril 2017

EIB 3391Y• Interface electronics in D-sub connector housing• Input: EnDat22 interface for specific linear and angle encoder versions• Output: Yaskawa serial interface

The EIB 3391Y enables you to connect
specific linear and angle encoder versions
to the servo drives of the Sigma 7 series(series SGD7 and SGDV-0FA01A withv0021 firmware or higher) from Yaskawa.
Please note:• The encoder is adjusted without the EIB
directly over the EnDat interface at theencoder, e.g. with the PWM 20. Atpresent, the EIB 3391Y is supported onlyby the PWM 20.
• The zero set function (datum setting) is
not supported by the EIB• The encoder is powered over the EIB(note the encoder’s power consumptionPM)

Linear encoders
The EIB supports only the following LIC orLC encoders:• LIC 2100 with AK LIC 211 scanning headwith 50 nm or 100 nm measuring step
• LIC 4100 with AK LIC 411 scanning headwith 5 nm measuring step
• LC 115 with 10 nm measuring step
• LC 211 with 10 nm measuring step
• LC 415 with 10 nm measuring step
Please also note:• A special version of the EIB 3391Y isnecessary for every measuring step
• Maximum permissible measuring lengthMeasuring step 5 nm:<9mMeasuring step 10 nm:< 18 mAngle encoders
The EIB supports angle encoders withposition values/rev of 26 to 29 bits. There
are limitations to maximum shaft speed(see Connectable encoders in theSpecifications). The following angle
encoders are supported:• RCN 2x10
• RCN 5x10
• RCN 8x10
• ROC 2x10, ROC 7x10
• ECA 4x1x
An angle encoder can be used together
with the EIB in a “full closed” application
only for position measurement. It cannot
be used for a “direct drive” application,i.e. as a motor encoder for commutation.
The adjustment parameters for connection
to servo drives from Yaskawa are listed in
the S Specifications of the respectiveencoder.
