SEW-EURODRIVE MOVIDRIVE MDX60B/61B Series: Comprehensive Module Range and Technical Overview
The SEW-EURODRIVE MOVIDRIVE MDX60B and MDX61B series represents one of the most widely deployed variable-speed drive platforms in global heavy industry. Installed across petrochemical refineries, nuclear auxiliary systems, cement plants, steel mills, and offshore platforms, the MDX60B/61B line covers output power from 0.55 kW to 315 kW in 400 V and 500 V supply variants. Its modular architecture — separating the power section (MDX60B) from the application controller (MDX61B) — allows independent replacement of drive electronics without disturbing the mechanical installation, a critical factor in continuous-process environments where unplanned downtime carries direct production cost.
The Evolution of MOVIDRIVE MDX60B/61B Architecture
SEW-EURODRIVE introduced the MOVIDRIVE B generation as the successor to the MOVIDRIVE A (MDV60A/61A) platform, with production of the B-series commencing in the early 2000s. The architectural shift from A to B introduced a unified parameter structure (MOVITOOLS MotionStudio), improved EMC filtering, and a standardized fieldbus option card slot (SBus, PROFIBUS, DeviceNet, CANopen, EtherNet/IP, PROFINET) that replaced the fixed-protocol variants of the A-series.
The MDX60B designates the basic inverter unit (without integrated application controller), while MDX61B adds the onboard IEC 61131-3 application controller with 512 KB user program memory. Both share identical power hardware, enabling field upgrades from MDX60B to MDX61B by controller board replacement only. The series entered its mature/end-of-active-production phase, with SEW-EURODRIVE transitioning new designs toward the MOVI-DRIVE modular (MDX91A) platform. However, the MDX60B/61B installed base remains extensive, and SEW-EURODRIVE continues to supply spare parts and repair services. Third-party distributors such as DriveKNMS maintain independent stock of both current and discontinued variants to support long-term maintenance contracts.

Sourcing Hard-to-Find & Obsolete MOVIDRIVE MDX60B/61B Parts
As the MDX60B/61B series transitions from active production to long-term support status, procurement of specific power ratings, voltage variants, and option card combinations becomes progressively more difficult through standard distribution channels. SEW-EURODRIVE's own spare parts program covers the most common variants, but low-volume or regionally discontinued SKUs — particularly sub-1.5 kW units such as the MDX60A0055-5A3-4-00 and early A-suffix production runs — are frequently unavailable through OEM channels with lead times of 8–20 weeks.
DriveKNMS maintains an independent inventory of MDX60B/61B units sourced from decommissioned plant equipment, surplus OEM stock, and authorized repair channels. All units are tested to functional specification before dispatch. For facilities operating under long-term maintenance agreements or requiring guaranteed spare availability for 5–10 year horizons, DriveKNMS offers consignment stocking arrangements for critical MDX60B/61B variants.
Quality Control for the MOVIDRIVE MDX60B/61B Range
The MDX60B/61B power section integrates IGBT modules, DC bus capacitor banks, gate driver boards, and a control PCB communicating over an internal backplane. Each of these subsystems requires independent verification before a unit is classified as serviceable.
DriveKNMS applies the following test protocol to all MDX60B/61B units processed through its facility: (1) Visual inspection of IGBT module condition, bus bar integrity, and capacitor ESR measurement. (2) DC bus pre-charge circuit functional test. (3) Gate driver signal verification under no-load switching conditions. (4) Full parameter restore via MOVITOOLS MotionStudio with factory default verification. (5) Motor simulation load test at rated output current for minimum 30 minutes. (6) Fieldbus option card communication test (where fitted) against a reference PLC. Units that fail any stage are quarantined and not offered for resale. Test records are retained and available upon request.
