ABB ACS880-01-07A4-7

Let's delve into a detailed introduction of the **ABB ACS880-01-07A4-7** frequency converter.
First and foremost, this is an **AC variable frequency drive (VFD)** belonging to ABB's flagship ACS880 series. Unlike the previously introduced high-power cabinet-type or wall-mounted models, this product falls into a more compact category structurally.
We can break down this model number to understand its key information:
*   **ACS880**: **Product Series**
*   **01**: **Mechanical Construction/Product Type**
*   **07A4**: **Rated Output Current**
*   **7**: **Voltage Level**
### 1. Product Series: ACS880
The ACS880 is a **fully compatible, modularly designed standard AC drive series** launched by ABB. It is the core of ABB's drive product line, renowned for its flexibility, powerful features, and excellent performance.
**Core features of the ACS880 series include:**
*   **Universal Platform:** Unified firmware and user interface simplify selection, design, commissioning, and maintenance.
*   **Modular Design:** Users can easily add various optional functional modules, such as I/O extension cards, fieldbus adapters, encoder interface cards, etc., to meet specific application needs.
*   **High-Performance Control:** Supports **DTC (Direct Torque Control)** technology, providing outstanding dynamic speed and control accuracy, high starting torque, and extremely fast torque response.
*   **Comprehensive Safety Functions:** Standard integrated **Safe Torque Off (STO)** function meets SIL 3/PL e safety levels, eliminating the need for additional safety relays.
*   **Powerful Communication Capabilities:** Supports almost all mainstream industrial networks (e.g., Profinet, EtherNet/IP, Modbus TCP, EtherCAT) via adapter modules.
*   **User-Friendly:** Unified **PC tool (Drive composer)** and **hand-held control panel** provide intuitive parameter setting, monitoring, and diagnostics.
### 2. Model Code详解: ACS880-01-07A4-7
Now, let's analyze the subsequent codes one by one:
*   **01**:
    *   This refers to the drive's **product type or mechanical construction**. The code **`-01`** is crucial; it indicates that this drive is a **single drive module (often referred to as a "book-type" module)** within the ACS880 series.
    *   This means it is not a complete, self-contained unit with an enclosure, but rather a **compact power module designed for installation inside a control cabinet**. It typically requires additional auxiliary equipment, such as an external circuit breaker, contactor, cooling fan, and a separate control unit (e.g., the ACS880-UX control panel adapter module), to form a complete drive system.
*   **07A4**:
    *   This part indicates the drive's **rated output current**. This is the most critical performance parameter.
    *   `07A4` needs to be interpreted as a code. According to ABB's naming convention, it corresponds to a **rated output current of 10.7 Amps**.
    *   This current value determines the size of the motor it can drive. For a 400V voltage level, a 10.7A drive can typically drive a standard four-pole AC motor rated around **5.5 kW / 7.5 HP** (please consult the official selection guide for specifics).
*   **7**:
    *   This number represents the **input voltage level**.
    *   `7` corresponds to **400V** three-phase AC power (-7 denotes 400V class, -5 denotes 500V class, -3 denotes 690V class). This means the drive module is designed for standard **380V/400V/415V, 50/60Hz** industrial power grids.
### 3. Summary and Application
**The ABB ACS880-01-07A4-7 can be summarized as:**
> A single drive power module of type 01 within the ACS880 series. It has a rated output current of 10.7A and is designed for 400V AC motors. It is a compact core power component that needs to be integrated into a control cabinet and used alongside an external control unit.
**Typical Application Areas:**
Due to its compact modular design, it is highly suitable for integration into OEM (Original Equipment Manufacturer) machinery or complete control cabinets. Application areas include:
*   **Packaging Machinery:** Filling machines, labeling machines, packaging machines.
*   **Material Handling:** Small conveyor belts, sorting systems.
*   **Food and Beverage Industry:** Small mixers, extruders.
*   **General Industrial Machinery:** Various automated equipment requiring compact design and flexible integration.
**Important Notes:**
1.  **Not Standalone:** This is a power module and **cannot be used alone**. It must be installed inside a distribution cabinet and combined with a control unit, circuit breakers, fuses, and other auxiliary components to form a complete system.
2.  **Cooling Requirements:** The module itself usually relies on the cabinet's air duct or forced air cooling for heat dissipation; its cooling requirements must be considered during cabinet design.
3.  **Professional Integration:** Installation and system integration must be performed by qualified electrical engineers following ABB's installation guidelines.
4.  **Accurate Information:** For project selection or procurement, always refer to the latest official selection guide, as current codes may be updated.
