SEW-EURODRIVE MDX61B0040-5A3-4-0T MOVIDRIVE B Application Inverter

Overview

The SEW-EURODRIVE MDX61B0040-5A3-4-0T is a MOVIDRIVE B series application inverter for 4.0kW three-phase asynchronous and synchronous servo motors. The SEW-EURODRIVE MDX61B0040-5A3-4-0T supports vector control, closed-loop encoder feedback and positioning functions, and can be fitted with optional communication cards for PROFIBUS-DP, EtherCAT and other fieldbus connections. It adopts four-quadrant operation with built-in brake chopper, suitable for lifting, conveyor and packaging machinery with frequent acceleration and deceleration. The SEW-EURODRIVE MDX61B0040-5A3-4-0T is widely stocked as spare replacement for industrial automation control cabinets.

Features

The SEW-EURODRIVE MDX61B0040-5A3-4-0T delivers stable 4.0kW rated power under 380V to 500V three-phase AC supply. It supports U/f, VFC vector control and CFC servo control modes, and can realize high-precision speed and position control with encoder feedback. The SEW-EURODRIVE MDX61B0040-5A3-4-0T reserves one expansion slot for optional bus interface cards and encoder evaluation cards. It integrates comprehensive protection functions including overcurrent, overvoltage, undervoltage, over-temperature, motor overload and earth fault detection. The SEW-EURODRIVE MDX61B0040-5A3-4-0T uses standard vertical cabinet installation and MOVITOOLS MotionStudio software for parameter setting, backup and diagnosis.

Specs

Device Type: MOVIDRIVE B application inverter Model: SEW-EURODRIVE MDX61B0040-5A3-4-0T Rated Power: 4.0 kW Input Voltage: 3 × 380 V AC to 500 V AC, 50/60 Hz Output Frequency: 0 Hz to 400 Hz Control Mode: U/f, VFC vector control, CFC servo control Built-in Function: Integrated brake chopper, 4-quadrant operation Expansion: Optional fieldbus card, encoder card Programming Software: MOVITOOLS MotionStudio Mounting: Vertical installation inside control cabinet Protection Grade: IP20 Application: Conveyor system, packaging machine, lifting equipment, material handling, process automation

Principle

The SEW-EURODRIVE MDX61B0040-5A3-4-0T receives setpoint commands from PLC or HMI via terminal signals or fieldbus. The internal control unit calculates the output voltage and frequency according to the control algorithm, and drives the IGBT power stage to output PWM waveform for the motor. When the motor runs in generator state, the brake chopper consumes regenerative energy on the brake resistor. The inverter continuously monitors current, voltage and temperature. When abnormal working conditions are detected, the SEW-EURODRIVE MDX61B0040-5A3-4-0T triggers fault alarm or safe shutdown and records fault codes.

Applications

The SEW-EURODRIVE MDX61B0040-5A3-4-0T is used for variable speed drive of conveyors, packaging machines and lifting equipment in factory automation lines. It serves speed regulation and positioning control for pump and fan feeders with high dynamic requirements. The SEW-EURODRIVE MDX61B0040-5A3-4-0T applies to spare stock and emergency repair of existing MOVIDRIVE B drive systems. It also supports retrofit and upgrade projects of old SEW drive cabinets.
