Description
B&R 8AC120.60-1 Encoder Interface Plug-in Module
Product Dimensions:
The B&R 8AC120.60-1 is a high-performance plug-in module designed for use with B&R’s ACOPOS servo drive series. Specifically, it is an encoder module that allows the drive to interface with various feedback systems, ensuring high-precision motion control.
1. Product Description
The 8AC120.60-1 is an interface module that provides support for EnDat 2.1 encoders. It is designed to be inserted into the expansion slots of ACOPOS multi or ACOPOS servo drives. This module enables the drive to read position data from motors equipped with EnDat encoders, which are industry standards for high-resolution absolute position feedback.
2. Technical Parameters

3. Key Advantages
-
High Precision: Supports 1 Vpp sinusoidal signals, allowing for high interpolation and extremely smooth motion at low speeds.
-
Absolute Positioning: By using the EnDat protocol, the system knows the exact position of the motor upon power-up without requiring a homing run.
-
Plug-and-Play: Easily integrates into existing B&R ecosystems via the standard ACOPOS slot system.
-
Robustness: Designed for industrial environments with high resistance to electromagnetic interference (EMI).
4. Important Considerations (Precautions)
-
Electrostatic Discharge (ESD): This module contains sensitive electronic components. Always use an ESD wrist strap during installation.
-
Power Down: Never insert or remove the module while the servo drive is powered on. This can damage both the module and the drive.
-
Cable Shielding: Ensure that the encoder cable is properly shielded and grounded to prevent signal noise, which can cause “Encoder Fault” errors.
-
Compatibility: Verify that the motor’s encoder version is EnDat 2.1; while some EnDat 2.2 encoders are backward compatible, always check the motor datasheet first.
5. Typical Applications
The 8AC120.60-1 is utilized in industries requiring synchronized, high-speed, and high-accuracy movements:
-
CNC Machining: For precise axis positioning and path control.
-
Packaging Machinery: Synchronizing multiple axes for high-speed wrapping and labeling.
-
Robotics: Providing feedback for multi-joint robotic arms.
-
Semiconductor Manufacturing: Handling delicate components where vibration-free motion is critical.
