Here's a breakdown of the model number and its meaning:

ACS580: This indicates the series or product family of the inverter. In this case, it's the ACS580 series.

01: This part of the model number refers to the hardware variant or frame size of the inverter. Different frame sizes may have different physical dimensions and power ratings.

088A: The '088' typically represents the nominal current rating of the inverter, which suggests that this model is designed to handle a maximum current of 88 amperes. The 'A' may indicate additional features or options specific to this variant.

4: This digit usually specifies the voltage rating of the inverter. Without additional information, it's difficult to determine the precise voltage rating. But generally, '4' could indicate a voltage rating suitable for three-phase AC power systems like 380-480 volts.

The ACS580 series of inverters are commonly used in various industrial applications for controlling the speed and torque of AC motors. These inverters provide energy efficiency, precise control, and protective features to ensure reliable and efficient operation of motor-driven systems.
