Application & Fault Scenarios
Suitable for 400 V three-phase motors on extruders, centrifuges, hoists, heavy conveyors, mixers, packaging lines and machine tools needing adjustable speed and torque control.

Check motor insulation, input voltage, acceleration time, braking resistor and communication wiring before replacing the drive.

FAQ
Q1: What is the Emerson UNI4401?
A legacy Unidrive AC drive, 45 kW / 60 HP, 400 V three-phase, large-frame panel-mount inverter for heavy industrial use.
Q2: Can UNI3405 replace UNI4401?
No. UNI3405 is rated for 37 kW, so it is too small for a 45 kW UNI4401 application unless the load and current are reduced.
Q3: Does UNI4401 support servo or vector control?
Yes. Depending on configuration, it supports V/f, open-loop vector, RFC and servo modes.
