Servo Axis Module | Allen-Bradley 2094-AMP5-S Kinetix 6000

The 2094-AMP5-S is a 200 V class Kinetix 6000 single-axis inverter module designed for multi-axis motion control applications. Operating on a 200/230 V AC nominal bus system, it delivers 1.2 kW of continuous output power with a 5 A inverter current rating. The module features integrated Safe Torque-Off (STO) functionality, permitting safe access to machine work zones by removing rotational torque from the motor without dropping main control power.

Power Rail Architecture & Bus Integration

The 2094-AMP5-S mounts directly onto a Bulletin 2094 power rail, receiving DC bus voltage and 24 V DC control power from the system's Integrated Axis Module (IAM). This modular bus architecture eliminates individual AC line power wiring for downstream axes, streamlining enclosure layout and reducing connection points across multi-axis drive configurations.

Integrated Safe Torque-Off Operation

The internal Safe Torque-Off circuitry (-S variant) meets SIL 3 / Category 3 safety requirements by hardwiring safety control signals directly to the drive output stage. When activated by an external safety relay or interlock, the STO hardware instantly gate-disables the output power transistors. This prevents the connected servo motor from generating rotational torque while retaining drive logic power, enabling fast machine restarts once the safety loop is cleared.

Installation Guidelines

Mount the axis module onto a clean, unpainted 2094 power rail position, ensuring the mounting hardware is torqued securely to maintain ground integrity and high-frequency EMI shielding. Maintain a minimum 50 mm clearance above and below the module assembly to facilitate natural convective air cooling across the heatsink structure.

Frequently Asked Questions

Q: How does the 2094-AMP5-S receive AC line power within a multi-axis assembly?A: It does not connect directly to AC line mains. Instead, it draws shared DC bus and control power through the Bulletin 2094 power rail from a leader Integrated Axis Module (IAM).

Q: What is the main operational benefit of the Safe Torque-Off feature?A: Safe Torque-Off disables drive output power to stop motor torque generation while keeping drive control electronics powered, avoiding long reboot delays after opening safety gates.
