Product Overview

The Allen-Bradley 2094-BMP5-S​ is a Kinetix 6000 series multi-axis servo drive axis module manufactured by Rockwell Automation, designed to be installed in a 2094-series Kinetix 6000 rack alongside a 2094 Power Supply Module (such as 2094-PS1 or 2094-PS2) and a 2094 Interface Module (such as 2094-EN02-S or 2094-ENETCAT) to form a complete integrated motion control solution for ControlLogix® or CompactLogix™ platforms using SERCOS® II (IEEE-1393) or EtherNet/IP™ with the appropriate interface. The 2094-BMP5-S​ provides a continuous output current of 5.0 Arms (7.0 A DC equivalent on 400 V DC bus typical) and a peak current of 10.0 Arms for acceleration/deceleration periods, suitable for driving Allen-Bradley MP-Series (MPM, MPL, MPA) and TL-Series permanent magnet brushless servo motors in the corresponding power range. The module accepts the regulated DC bus from the shared 2094 power supply module (nominally 360–528 V DC derived from 230/460 V AC 3-phase or 1-phase input at the supply module) and synthesizes a PWM voltage output to the servo motor via the integral shielded bulkhead male connector (typically mating with 2090-XXNPMP-… servo motor power/feedback cable).The 2094-BMP5-S​ communicates motion commands, feedback data, and drive status over the SERCOS optical ring (when paired with a SERCOS interface module such as 2094-EN02-S) or indirectly via the rack’s backplane when used with an EtherNet/IP interface—allowing the Logix controller to execute coordinated motion instructions (MAM – Motion Axis Move, MAG – Motion Axis Gear, MAS – Motion Axis Stop, etc.) with sub-millisecond determinism. The axis module includes built-in brake control output, an auxiliary 24 V DC logic input for Safe Torque Off (STO) when used with the appropriate option card or system design, and comprehensive drive-level diagnostics accessible through Studio 5000 Logix Designer’s drive properties and through PanelView™ terminals on the same network. Front-panel LEDs indicate module status (OK/FLT), bus voltage presence, and SERCOS ring activity. The 2094-BMP5-S​ is a key building block of the Kinetix 6000 multi-axis architecture—where one power supply feeds multiple BMP axis modules in a single 2094 chassis—delivering space-efficient, cost-effective distributed servo control for packaging lines, converting machinery, assembly test stands, and material handling systems requiring 2–8 coordinated axes from one DC bus. Although the Kinetix 6000 family has been succeeded in new designs by Kinetix 5700 (2198), the 2094-BMP5-S​ remains extensively stocked for MRO, legacy system support, and sparing of installed Kinetix 6000 bases worldwide.

Technical Specifications

Main Features and Advantages

The Allen-Bradley 2094-BMP5-S​ provides the power stage and local intelligence for one servo axis within the Kinetix 6000 multi-axis rack, delivering several differentiating benefits that made the Kinetix 6000 platform the de facto standard for integrated Logix-based motion.Shared DC bus efficiency in multi-axis systems: Unlike standalone single-axis drives, the 2094-BMP5-S​ draws from a common DC bus supplied by a single 2094-PSx power supply module. In multi-axis machines (e.g., a packaging machine with two feed axes, a rotary indexer, and a pick-place Z-axis), regenerative energy from decelerating axes is returned to the DC bus and reused by simultaneously accelerating axes—reducing total input power requirement and minimizing heat dissipation. A single 2094-BMP5-S​ axis module occupies only 1.5 slots in the 2094 chassis, allowing up to 4 axis modules (plus power and interface) in a standard 3-slot-width 2094 rack configuration, or more with the extended chassis—maximizing axis density per cabinet volume.Seamless Logix integration via SERCOS or EtherNet/IP: When paired with a 2094-EN02-S (SERCOS II fiber ring) or 2094-ENETCAT (EtherNet/IP with CIP Motion®) interface module, the 2094-BMP5-S​ is automatically discovered by RSLinx and appears in Studio 5000 Logix Designer as a motion axis object. Engineers configure motor/drive parameters (or auto-tune online), set up cam tables, software travel limits, homing methods, and gain scheduling—all within the same project that contains the machine’s sequential logic. The Kinetix 6000 motion instruction set (MAM, MAG, MAS, MAH, MATC, etc.) executes with the same deterministic performance as the Logix PAC’s boolean/analog I/O scan, unifying motion and sequential control in one controller without a separate motion card or proprietary language.Built-in brake control and safety options: The 2094-BMP5-S​ contains an internal 24 V DC brake relay driver that automatically applies/removes the servo motor’s holding brake according to axis state (e.g., brake released when servo-enabled and in closed-loop position, brake engaged on disable or fault). No external brake relay is needed for properly specified brakes. When the optional Safe Torque Off (STO) terminal is wired and activated (either via a safety relay or a GuardLogix safety output), the 2094-BMP5-S​ removes torque-producing current from the motor while maintaining feedback and communication—supporting SIL 3 / PL e machine safety stops per EN ISO 13849-1and IEC 61508without disconnecting the main contactor, reducing wear and restart time.Comprehensive diagnostics and tuning tools: The module’s status LEDs (OK, FLT, BUS, SERCOS Link) give at-a-glance health indication. Through Studio 5000’s Drive Properties or the web server on newer interface modules, technicians can view real-time bus voltage, output current (RMS and peak), motor temperature (if motor has thermistor/KTY84), feedback integrity, and fault history with timestamp and parameter snapshot. The integrated auto-tune function of the Kinetix 6000 system can be run via the software to optimize position/speed loop gains for the connected mechanical load—a critical time-saver during machine commissioning. All drive faults propagate to the controller as motion group faults, enabling centralized alarm handling in the PLC program.Wide motor and feedback compatibility: The 2094-BMP5-S​ works with Allen-Bradley’s MPL (low-inertia), MPM (food-grade / stainless), MPA (absolute encoder) and TL-Series servo motors, as well as legacy and some third-party servos provided the feedback type (Hiperface DSL, EnDat 2.1/2.2, resolver) is supported by the Kinetix 6000 platform and the motor’s voltage/current ratings fall within the 5 A continuous / 10 A peak envelope. This flexibility allows OEMs to standardize on the 2094-BMP5-S​ across multiple machine variants differing only in motor frame size.
