ABB ACS580MV Medium voltage AC drives ACS580MV-07-0021A-100

ACS580MV-07-0021A-100

Compared with other models in the ACS580MV series, the differences between ACS580MV-07-0021A-100 are mainly reflected in the following aspects:

### Power parameters

- **Rated current**: "0021A" in the model indicates that the rated current of the inverter is 21A. The rated currents of different models are different. For example, the rated current of ACS580MV - 07 - 0267A - 110 is 267A. Different rated currents determine the different motor powers it is suitable for. This model is suitable for relatively small power motors, while other high-current models can be adapted to high-power motors.

- **Applicable voltage level**: "100" may mean that this model is adapted to 10kV voltage level, while other models in the series may be adapted to different voltage levels such as 3.3kV, 6kV, 11kV, etc., to meet the voltage requirements of different power grids and motors.

### Application scenarios

- **Load type applicability**: Due to its relatively small rated current and power, it is more suitable for driving small constant torque loads (such as small conveyor belts) or variable torque loads (such as small fans, water pumps). Models with large rated current can be used for large industrial equipment, such as large mine hoists, large air compressors, etc.

- **System scale**: In some small industrial production systems or local process flows, ACS580MV-07-0021A-100 is sufficient to meet the motor drive and speed regulation requirements; for the whole plant automation system of large factories, other models with higher power and higher performance may be selected to drive key large equipment.

### Functional characteristics

- **Control accuracy and dynamic response**: Although the overall control performance of the ACS580MV series is good, the smaller power models may have slight differences in control accuracy and dynamic response speed from the higher power models. The higher power models may use more advanced control algorithms and hardware configurations to meet the requirements of large equipment for precise control and fast response.

- **Extended functions**: Some large models may have more extended function interfaces, which are convenient for connecting more sensors, actuators or other automation equipment for complex communication and collaborative control. However, this model may focus on meeting basic motor drive and speed regulation functions, and has relatively few extended functions.

### Physical characteristics

- **Size and weight**: Generally, the ACS580MV-07-0021A-100 with lower power is relatively small in size and weight, occupies less space, and is easy to install in places with limited space; the high-power model has larger internal electrical components and heat dissipation devices, so the size and weight will also increase accordingly.

- **Heat dissipation requirements**: The lower-power model generates relatively less heat and has relatively lower requirements for heat dissipation conditions. Simple air cooling may be sufficient; high-power models may require more complex heat dissipation systems, such as water cooling.
