B&R 8AC120.60-1 ACOPOS EnDat 2.1 and SinCos Encoder Interface Module
| Place of Origin | Germany |
| Brand Name | B&R |
| Model Number | 8AC120.60-1 |
Product Overview
The B&R 8AC120.60-1 is an ACOPOS plug-in encoder interface module designed for evaluating EnDat 2.1 feedback devices and incremental encoders with sinusoidal input signals. It is installed in a compatible ACOPOS servo drive and provides the feedback interface required for closed-loop motor control and position measurement.
This module supports encoder monitoring, a synchronous RS485 serial interface and high-resolution sine/cosine signal evaluation. It is intended for ACOPOS installations where the original drive and motor use an EnDat 2.1 or compatible sinusoidal feedback configuration.
Main Features

Maintenance and Replacement Notes
Verify the complete model, ACOPOS drive model, installed slot, motor encoder protocol, encoder supply requirement, feedback cable and connector pin assignment. An EnDat 2.2, HIPERFACE, resolver or SSI interface module is not automatically interchangeable with the 8AC120.60-1.
Related Models
Related ACOPOS feedback modules include 8AC123.60-1 for incremental and SSI encoders, 8AC121.60-1 for HIPERFACE feedback and 8AC126.60-1 for EnDat 2.2 applications.
Inquiry and Supply Notes
