ABB ASFC-01C

Product introduction

The ASFC-01C is a high-performance servo feedback converter module from ABB, designed to bridge different feedback signal protocols in precision motion control systems. As a critical interface between absolute encoders and servo drives, it converts EnDat 2.2 and SSI signals into a format compatible with ABB servo drives, enabling seamless communication and precise position control.

With support for high-resolution encoders (up to 32 bits), ASFC-01C ensures accurate motion feedback, which is essential for applications requiring tight positioning tolerances, such as robotics, CNC machining, and precision assembly systems. Its compact design allows integration into space-constrained control cabinets, while robust signal conversion capabilities minimize latency, ensuring real-time responsiveness in dynamic motion scenarios. Whether used in new servo installations or retrofitting legacy systems with modern encoders, ASFC-01C delivers reliable performance, enhancing the accuracy and efficiency of motion control systems.

Core advantages and technical highlights

Multi-protocol conversion

ASFC-01C supports both EnDat 2.2 and SSI protocols, eliminating the need for multiple converter modules in systems with mixed encoder types. In an automotive assembly robot cell, this capability allows a single module to convert signals from an EnDat 2.2 encoder on a welding arm and an SSI encoder on a material handling axis, simplifying system architecture and reducing component costs.

High-resolution signal handling

With support for up to 32-bit resolution, ASFC-01C preserves fine position details from high-precision encoders. In a CNC milling machine, this ensures the servo drive receives position updates with 0.0001 mm accuracy, enabling the machine to achieve tight tolerances on complex workpieces. The module’s high clock frequency (10 MHz for EnDat) ensures these detailed signals are transmitted without delay, even during high-speed motion.

Robust signal integrity

ASFC-01C features 2.5 kV AC isolation and noise filtering, ensuring reliable operation in electrically noisy industrial environments. In a factory with nearby high-power motors and welders, the module maintains stable communication between encoders and drives, preventing position errors that could lead to product defects or equipment damage. Its error detection capabilities also alert the control system to signal anomalies, enabling proactive maintenance.

Typical application scenarios

In a robotic palletizing system, ASFC-01C plays a key role in ensuring precise arm movement:

• Converts EnDat 2.2 signals from the robot’s joint encoders into a format compatible with the ABB ACS800 servo drive.
• Enables real-time position feedback (updates every 100 µs) to maintain smooth motion during pallet stacking.
• Works alongside SD834safety modules to monitor encoder signals for unexpected position jumps, triggering a safe stop if anomalies are detected.

In a precision textile machine, ASFC-01C supports high-speed thread positioning:

• Converts SSI signals from the yarn guide encoder (32-bit resolution) to control the servo drive.
• Ensures the guide moves with 0.01 mm accuracy, preventing thread breakage and ensuring uniform fabric quality.
• Its compact size allows integration into the machine’s control panel, which has limited space for additional electronics.

Installation, commissioning and maintenance instructions

Installation preparation

Before installing ASFC-01C, ensure the servo drive system is powered off. Verify that the operating voltage (5 V DC) matches the power supply output. Mount the module on a 35 mm DIN rail or secure it to a panel using M3 screws (torque to 0.5 Nm), ensuring a minimum of 10 mm clearance around the module for airflow. Use shielded twisted-pair cables for encoder connections, with a maximum length of 10 meters to maintain signal integrity. Connect the encoder to the input terminals (EnDat or SSI) and the servo drive to the output terminals, following the wiring diagram provided with ASFC-01C. Ground the cable shields at both ends to minimize electromagnetic interference.

Maintenance suggestions

Inspect ASFC-01C monthly by checking the power and communication status LEDs—steady green indicates normal operation, while flashing or red LEDs signal issues. Clean the module’s connectors quarterly with compressed air to remove dust. During troubleshooting, use an oscilloscope to verify encoder signal quality at the module’s input terminals. If communication errors persist, check for loose connections or damaged cables before replacing ASFC-01C. When replacing the module, ensure the new unit is configured with the same protocol settings as the original to maintain compatibility with encoders and drives.
