Main Features and Advantages
Compact and Space‑Saving Design: The 25A‑D4P0N114 is built in Frame A size, the smallest in the PowerFlex 523 lineup, with dimensions of just 152 × 72 × 212 mm. Its compact footprint allows side‑by‑side mounting with only a 50 mm air‑flow gap required at the top and bottom, maximising cabinet space utilisation and simplifying integration into tight control panels.
Flexible Motor Control Modes: The 25A‑D4P0N114 supports both standard V/Hz control for basic applications and Sensorless Vector Control (SVC) for applications that demand higher torque performance at low speeds. This versatility allows the drive to handle a broad range of loads, from centrifugal fans and pumps to conveyors and positive displacement pumps where speed regulation accuracy is more critical.
Integrated EMC Filter and Brake Chopper: This model includes a built‑in EMC filter to minimise conducted emissions, simplifying compliance with electromagnetic compatibility requirements and reducing the need for external filtering components. Additionally, the integrated brake chopper enables fast deceleration of high‑inertia loads when paired with an external braking resistor, eliminating the need for a separate braking unit and saving both cost and panel space.
Flexible Communication and Easy Programming: The 25A‑D4P0N114 comes with an embedded RS485/DSI port that supports Modbus RTU protocol, providing a low‑cost networking solution for connection to PLCs and HMIs. A USB port is also provided for direct connection to a PC, allowing quick configuration, parameter backup, and firmware updates using Rockwell Automation’s Connected Components Workbench software—all without the need for a special programming cable.
Rich I/O and Application‑Specific Configuration: The 25A‑D4P0N114 offers 5 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output, providing ample connectivity for local control and feedback signals. The analog input can accept a 0–10V or 4–20mA signal for remote speed reference or PID control, making the drive well‑suited for closed‑loop pressure, flow, and temperature regulation in a wide range of process applications.
