Frequently Asked Questions

• How long is this feedback cable? This model is 20 meters long, designed for extended-distance installations.
• What types of signals does it carry? It carries only encoder feedback signals (SIN/COS or resolver), not motor power.
• What is the drive-end connection? It features flying leads (individual wires) for connection to the drive's terminal block.
• Is this suitable for dynamic flexing applications? No, it is a standard (non-flex) cable for fixed or minimally flexing installations.
• Which Rockwell drives is it compatible with? It is designed for use with the Allen-Bradley Bulletin 2090 series of servo drives.
