SEW‑EURODRIVE MOVIDRIVE MDX61B0008-5A3-4-0T – Compact 400 V Vector Inverter for Precise Motion on 3 kW‑class Drives

The MDX61B0008-5A3-4-0T is part of SEW‑EURODRIVE’s MOVIDRIVE B family—typically used where you need reliable speed/torque control and simple positioning on conveyors, packaging machines, indexing tables, and light gantry axes. What stands out, in many cases, is the consistent handling across the MDX61B range: once you’ve commissioned one with MOVITOOLS, the next one goes fast. You might notice that even in tighter cabinets, this “0008” frame stays compact while still offering robust 380–500 V three‑phase performance.

Key Features

• 380–500 V three‑phase (5A3) – Suited for global 400 V class mains, 50/60 Hz.
• Approx. 8 A output rating – Typically applied to motors around 3.0 kW at 400 V, depending on duty and cooling.
• High‑performance vector control – Stable speed at low frequencies and better torque response for conveyors, winders, and position moves.
• Integrated technology functions (IPOSplus) – Handy for simple positioning, camming, or sequence logic without a separate PLC in many cases.
• Flexible I/O – 24 V digital I/O plus analog input support (0–10 V / 4–20 mA) for quick integration with PLCs and sensors.
• Fieldbus-ready – Optional cards for PROFINET, PROFIBUS, EtherNet/IP, EtherCAT, and more; service access via RS‑485.
• Booksize cabinet mounting – IP20, forced‑air cooling; easy to line up multiple axes with clean wiring top/bottom.
• Energy handling – External braking resistor connection for dynamic stops; useful on vertical axes or fast indexing.
• Fast commissioning – Parameter backup, keypad support, and MOVITOOLS MotionStudio make repeats painless.

Technical Specifications

Related or Supporting Products

• MDX61B0011-5A3-4-0T – Higher current rating (~11 A) for ~4 kW motors at 400 V.
• MDX61B0008-5A3-4-0T with fieldbus option cards – Add one of the following as needed:
  • DFP21B (PROFIBUS DP)
  • DFS21B (PROFINET)
  • DFE33B (EtherNet/IP)
  • DFE24B (EtherCAT)
  • DMC21B (DeviceNet)
• DBG60B keypad – Local display/commissioning and quick parameter copy.
• Braking resistor (SEW matched type for MDX61B 0008) – For dynamic deceleration and vertical loads.
• Line reactor / EMC filter – Improves mains quality and compliance in noise‑sensitive installations.
• SEW geared motors with encoders (e.g., helical‑bevel series) – Closed‑loop operation for precise speed/positioning.

From my experience, pairing this drive with a PROFINET or EtherNet/IP card cuts integration time when you’re standardizing on a single PLC platform. Maintenance teams also like the DBG60B for quick swaps—copy parameters, power up, and you’re back online in minutes.

Installation & Maintenance

• Cabinet & ventilation – Mount vertically in an IP54/Type 12 cabinet; allow top/bottom clearances for airflow; avoid dust/oil mist and excessive vibration.
• Wiring – Use properly sized shielded motor cables; bond shields 360° at the drive; keep control wiring separate from power; ground the DC‑link and chassis points solidly.
• Braking – Size an external braking resistor when rapid stops or overhauling loads are present; follow SEW’s resistor/thermal guidelines.
• Commissioning – Run motor ID if applicable; verify direction and encoder polarity; save a parameter backup after acceptance testing.
• Routine care – Inspect fans/filters periodically; clean heat‑sinks; check terminal torque; review fault logs; update firmware via MOVITOOLS when recommended.
• Environment – Operate within 0…+40 °C (derate above); keep humidity non‑condensing; ensure mains quality within the specified tolerance.

Quality & Certifications

• CE compliance for EMC and Low Voltage directives
• UL/cUL listing for North American installations (typical for MOVIDRIVE B series)
• RoHS conformity
• Manufactured under ISO 9001 quality systems
• Manufacturer’s warranty support; our supply warranty: 365 days

One thing I appreciate is how forgiving the MDX61B tends to be during retrofits—parameter sets are portable, and the option slot strategy means you only add what you really need. If you’re replacing an older MDX61A/60A, this unit usually slots in with minimal rewiring, as long as you verify fieldbus and encoder options beforehand.
