HEIDENHAIN EIB 3391Y Yaskawa Signal Converter
The HEIDENHAIN EIB 3391Y connects specific linear and angle encoders with an EnDat22 interface to Yaskawa servo drives. The interface electronics are integrated into a D-sub connector housing. Each encoder measuring step requires a matching EIB version.

Compatibility and configuration
The product information specifies Yaskawa Sigma 7 servo drives in the SGD7 series and SGDV-0FA01A with firmware v0021 or higher. Supported linear encoders are LIC 2100 with AK LIC 211 at 50 nm or 100 nm, LIC 4100 with AK LIC 411 at 5 nm, and LC 115, LC 211 and LC 415 at 10 nm. Maximum measuring length is less than 9 m at a 5 nm measuring step or less than 18 m at a 10 nm measuring step.
Supported angle encoders include RCN 2x10, RCN 5x10, RCN 8x10, ROC 2x10, ROC 7x10 and ECA 4x1x with 26-bit to 29-bit position values per revolution. Maximum shaft speed is less than 1600 rpm at 27 bits, less than 800 rpm at 28 bits and less than 400 rpm at 29 bits. Angle encoders are for position measurement in a full-closed application, not direct-drive motor commutation.
The zero-set function is not supported. Encoder adjustment is performed directly through the encoder's EnDat interface without the EIB; the product information specifies PWM 20 support. Confirm the combination of servo drive, EIB version and encoder before ordering.
