SEW MCF40A0015‑5A3‑4‑00 AC Inverter Unit

Module Feature

MCF40A0015‑5A3‑4‑00 belongs to SEW MOVIDRIVE Compact MCF series inverter. It adopts VFC open‑loop control for asynchronous motors, power 1.5kW, 400V three‑phase input. Without fieldbus interface, controlled by analog and binary I/O. Built‑in brake chopper and multiple protection functions. Widely used for conveyors and general automation equipment.

Working principle

AC mains is rectified to DC voltage. IGBT module outputs variable‑frequency variable‑voltage AC for motor. VFC control adjusts output frequency and voltage to change motor speed. Brake chopper handles regenerative energy during deceleration.

Onboard components

Rectifier unit, DC‑bus capacitors, IGBT power module, control board, binary/analog I/O terminals, brake chopper, cooling fan, metal housing.

LED indicators

Status LED for power, running and fault alarm. Fault codes displayed on local operation panel.

Hardware self‑diagnosis

Read fault codes, monitor DC‑bus voltage, check fan running status, verify input power and I/O signal status.

Programming software

Parameter setup via SEW MOVITOOLS software or local keypad panel.
