A-B 2090-XNSM-M Servo Motor Cable

The Allen-Bradley 2090-XNSM-M is not a motor power cable or feedback cable. It is a Kinetix servo drive safety interconnect (Safe Torque Off / safety header cable) used in multi-axis servo drive systems.

Product Information

• Brand: Allen-Bradley (Rockwell Automation)
• Series: 2090 Kinetix accessories
• Part Number: 2090-XNSM-M
• Type: Safety Interconnect / Drive-to-Drive Header Cable
• Function: Safe Torque Off (STO) safety chain connection
• System: Kinetix multi-axis servo drive systems

Function (Simple Explanation)

This part is used to link safety circuits between multiple servo drives.

In a multi-axis system:

• One drive acts as the “first” safety node
• Middle drives use 2090-XNSM-M connectors
• Last drive uses a terminating version

So it ensures that when a safety stop occurs:
→ all drives enter Safe Torque Off (STO) state together

System Role

PLC / Safety controller
→ safety circuit
→ 2090-XNSM-M cable / header connection
→ multiple Kinetix servo drives
→ motors stop safely

It does not carry motor power or encoder signals.

Key Characteristics

• Used in multi-drive Kinetix safety configurations
• Supports drive-to-drive safety daisy chain
• Enables Safe Torque Off (SIL-rated safety function depending system design)
• Compact internal connector type (not a field cable like motor cables)
• Typically used with Kinetix 6000 / 6200 / 6500 / similar architectures

Typical Applications

• Multi-axis CNC machines
• Robotic systems with multiple servo axes
• Packaging lines with synchronized motion
• Industrial motion control systems requiring safety shutdown
• Kinetix rack-based servo drive cabinets

Key Features

• Ensures coordinated emergency stop across multiple drives
• Reduces external wiring complexity for safety circuits
• Supports industrial safety standards (SIL/PL depending system)
• Compact, reliable internal drive connection
• Designed specifically for Rockwell Kinetix systems

Precautions

• Not a motor cable (do not confuse with 2090 power/feedback cables)
• Only used in compatible Kinetix multi-axis safety architectures
• Incorrect installation can break STO safety chain
• Must follow Rockwell safety wiring manual
• Not interchangeable with standard servo cables
