Whether you manage pumps, conveyors, or general machinery, the Allen-Bradley PowerFlex 40P series provides a strategic balance of performance, scalability, and affordability—all in a compact, rugged design.

Flexible Power Options for a Range of Applications

The Allen-Bradley PowerFlex 40P series supports a wide range of voltage classes and horsepower ratings, helping you reduce the need for multiple drive models across your facility. This makes it easier to standardize control systems and reduce inventory complexity.

• 200–240V AC drives handle 0.4 to 7.5 kW (0.5 to 10 HP), supporting 2.3 to 33 Amps—great for small machines and localized motor control.

• 380–480V AC options provide 0.4 to 11 kW (0.5 to 15 HP) and 1.4 to 24 Amps—ideal for mid-range operations.

• 500–600V AC models deliver 0.75 to 11 kW (1 to 15 HP) and 1.7 to 19 Amps—perfect for high-demand equipment such as pumps, compressors, or material handling systems.

This range allows engineers to choose a drive that fits their needs without overpaying for unneeded power, making the Allen-Bradley PowerFlex 40P series a practical solution for OEMs and plant managers.

Advanced Input/Output Capabilities

The Allen-Bradley PowerFlex 40P supports a variety of control options and I/O configurations that reduce the need for external relays or complex wiring:

• Two semi-programmable digital inputs streamline setup for start/stop control.

• Five fully programmable digital inputs allow for customization to meet specific application logic.

• Two opto outputs and a programmable Form C relay output enable real-time motor feedback and status indication.

• Analog input/output options (0–10V or 0–20mA) are selectable via DIP switch and provide accurate control signals for automation systems.

These I/O capabilities simplify integration and give users more flexibility in tailoring drive behavior for different control environments.

Built-In Industrial Communication Options

The Allen-Bradley PowerFlex 40P series supports modern industrial networks and protocols without requiring extra hardware in most cases:

• Optional communication cards provide native support for DeviceNet, EtherNet/IP, ControlNet, PROFIBUS DP, and LonWorks.

• Wireless Bluetooth access through the DSI Wireless Interface Module (WIM) for remote monitoring and adjustment.

With seamless connectivity to PLCs and HMIs, the Allen-Bradley PowerFlex 40P helps reduce downtime and engineering overhead while enabling faster commissioning and diagnostics.

Energy Management and Feedback Control

The Allen-Bradley PowerFlex 40P series is designed to handle dynamic loads and ensure consistent motor performance while improving energy efficiency:

• Auto-detecting encoder feedback with 5V, 12V, or 24V DC line driver signals for accurate speed and position control.

• PWM frequency up to 250 kHz for smooth, noise-free operation.

• Ride-through functionality using half-DC bus operation to keep motors running during short power disturbances.

• DC bus sharing and pre-charge control, improving energy use across multiple drives in shared bus systems.

These features make the Allen-Bradley PowerFlex 40P not just cost-effective but also energy-conscious—a key factor for facilities pursuing sustainability goals.

Built for Harsh Industrial Environments

The Allen-Bradley PowerFlex 40P series is engineered for durability and flexibility in the field:

• Integrated brake resistors support rapid load deceleration in hoisting or conveyor applications.

• Compact frames like the 22D-B3P0N104 run up to 50°C ambient without additional cooling.

• Flexible mounting options, including DIN rail and enclosures ranging from NEMA 1/IP30 to NEMA 4/IP66.

• Optional IP30 conduit boxes improve protection in rugged environments.

For space-constrained or heat-sensitive setups, the Allen-Bradley PowerFlex 40P offers a high-performance drive in a footprint-efficient package.

Versatile Motor Control Capabilities

The Allen-Bradley PowerFlex 40P supports both open-loop and closed-loop control methods, offering flexibility across motion control needs:

• Closed-loop control with encoder feedback for high-precision speed regulation.

• Local Position Control (StepLogic) for basic motion profiles, with up to 8 steps stored in the drive.

• Zero-cross performance optimization for smooth motion transitions in bipolar mode.

• Multiple speed references from analog signals or network commands, useful for coordinated drives.

These built-in features allow the Allen-Bradley PowerFlex 40P series to handle everything from basic V/Hz control to more complex positioning tasks without expensive add-ons.
