What it is and what it runs
The ACS880-MU-Z-AINL4 listing tags an ABB ACS880-01-014A-5+E200 inverter drive rated 14 A and 7.5 kW / 10 HP. Mains side accepts 0 – 440 / 480 V three-phase at 47 – 63 Hz. Output frequency runs 0 – 500 Hz, which covers the high-speed spindle and process-pump cases without dropping into a larger frame.
Onboard I/O and thermal ceiling
On the control board you get 2 analog inputs, 2 analog outputs, 6 digital inputs and 2 digital outputs — enough to land a reference speed, run permissive, two feedback signals and a couple of status outputs without adding an FIO module. Thermal ceiling is max. 40 °C ambient; above that the output current has to be derated per the ACS880-01 curve, so cabinet ventilation and clearances are not optional in a warm panel. The enclosure is IP21, wall-mounted, sized 9.8 x 6.1 x 16 inch, weighing 7,82 kg.
Reading the listing — what's a 'Memory Card' doing on a drive line?
Type field reads Memory Card while Type of Product is Inverter Drive; the ACS880-MU-Z-AINL4 maps to the ACS880-01-014A-5+E200 inverter, so the Type line is a cataloguing quirk — the drive ships as the listed product.
Sourcing posture
The ACS880-MU-Z-AINL4 shares its catalog string with the ACS880-01-014A-5+E200 reference drive, so a panel specified around the E200 variant accepts this listing as a drop-in.
