Drive selection memo — ACS580-01, 90 kW normal duty
The 3ABD00046023-D: Efficiency class is IE2. If your project or region mandates IE3 or IE4 for motor-drive combinations, this unit may not meet code without additional measures — verify local regulations before specifying.
Normal-duty 169 A (In) is the continuous output current for typical variable-torque loads like pumps and fans. Heavy-duty 145 A (IhD) is the continuous current for constant-torque or high-starting-torque loads — conveyors, crushers, extruders. The drive's overload capability is built around these two curves; selecting the wrong duty class undersizes the drive for the load profile. WEEE category 4 (Large Equipment) applies for end-of-life disposal compliance in EU markets.
