Allen-Bradley 22D-D4P0N104 PowerFlex 40P AC Drive – 2HP (1.5kW) 480V 3-Phase VFD with Sensorless Vector Control

Product Overview

The 22D-D4P0N104​ is Allen-Bradley’s (Rockwell Automation) PowerFlex 40P series adjustable frequency AC drive, purpose-engineered to deliver 2 HP (1.5 kW) of variable speed motor control for pumps, fans, conveyors, packaging machines, textile machinery, and HVAC applications. As a member of the renowned PowerFlex 40 family, the 22D-D4P0N104​ combines a compact Frame B design with an IP20 NEMA Type Open enclosure, making it ideal for panel-mount installation inside industrial control cabinets where space is at a premium. The drive accepts a wide 342-528 VAC three-phase input (48-63 Hz) and delivers 0-460 VAC output at 4.0 A continuous current, driving 2 HP / 1.5 kW three-phase induction motors with precision and efficiency.At its core, the 22D-D4P0N104​ features dual control methodologies: traditional V/Hz (volts per hertz) control and advanced sensorless vector control (SVC). The sensorless vector algorithm estimates motor flux to deliver high starting torque and superior speed regulation even at low frequencies and under varying load conditions—without requiring a physical encoder feedback device. This makes the 22D-D4P0N104​ particularly effective for conveyor applications with fluctuating loads, pump systems requiring precise flow control, and fan arrays demanding energy-efficient speed modulation. The drive’s integrated process PID controller, StepLogic positioning capability, and DC injection braking further enhance its application flexibility, allowing it to function as an independent position controller or execute rapid deceleration cycles without mechanical wear.The 22D-D4P0N104​ is equipped with a built-in RS-485 communication port (DSI protocol) supporting Modbus RTU, enabling seamless integration with ControlLogix and CompactLogix PLC platforms via analog speed reference (0-10 VDC or 4-20 mA) or serial parameter access. Optional communication modules (22-COMM-D for DeviceNet, 22-COMM-E for EtherNet/IP) mount directly to the drive’s peripheral port, making the 22D-D4P0N104​ visible as a network node in Studio 5000 Logix Designer projects, with support for ControlNet, Profibus DP, BACnet, and LonWorks protocols. The operator interface consists of an integral LCD keypad with 4-digit display and 10 status LEDs, enabling quick parameter configuration, real-time monitoring of frequency and current, and local start/stop/jog control without external software.With 7 digital inputs (5 fully programmable, 2 partially programmable), 2 Form C relay outputs, 1 opto-isolated output, 1 analog input, and 1 analog output, the 22D-D4P0N104​ provides exceptional I/O flexibility for complex automation tasks. The drive achieves Category 3 Safe Torque Off (Series B) functional safety, integrated IGBT dynamic braking for high-inertia loads, and built-in motor overload protection with ground fault detection. Operating reliably across 0°C to +50°C ambient temperature, the 22D-D4P0N104​ meets or exceeds IEC 61800-9-2 IE2 energy efficiency requirements and carries UL Listed, cUL, CE (with external filter), C-TICK, and RoHS certifications. Although the PowerFlex 40P series was officially discontinued by Rockwell Automation (end-of-production June 30, 2025), the 22D-D4P0N104​ remains in high demand worldwide as new-surplus and tested-takeout inventory for lifecycle support of existing installations, serving as the recommended upgrade replacement for earlier PowerFlex 4 series drives such as the 22A-D4P0N104.
