Description
SEW MDX61B0015-5A3-4-0T | 1.5 kW MOVIDRIVE Inverter
Product Introduction
The SEW-EURODRIVE MDX61B0015-5A3-4-0T is a size-1 MOVIDRIVE B application inverter intended for industrial motor control. Unlike a basic fixed-function VFD, the MDX61B platform supports multiple control methods, including U/f, VFC, CFC, and servo control, making the MDX61B family suitable for both asynchronous and synchronous motion applications.
This specific 0015 configuration is rated for 1.5 kW motor power, with 3 × 380–500 VAC supply and a 4.0 A rated output current. The -0T designation is important: SEW documentation lists it as the application/technology version, rather than the standard MDX61B -00 version. The technology version provides additional application functionality, including electronic cam and internal synchronous operation capabilities.

Application Scenarios & Pain Points
Legacy MOVIDRIVE B Replacement
The MDX61B0015-5A3-4-0T is particularly relevant when maintaining an existing MOVIDRIVE B installation where the drive’s exact application version matters.
Replacing it with a physically similar MDX61B standard version can remove application functions that the machine control system expects.
Conveyor and Material-Handling Equipment
The 1.5 kW configuration is appropriate for smaller industrial drive applications where controlled acceleration, deceleration, speed regulation, or positioning functions are required.
The drive supports multiple motor-control strategies rather than being restricted to simple scalar control.
Synchronous Motion Systems
MOVIDRIVE B supports servo-oriented control in addition to asynchronous motor control. This makes the platform relevant to machines where coordinated motion or internal synchronization is part of the control architecture.
Electronic Cam Applications
The -0T technology version is significant for machines using application-level motion functions. Documentation for the technology version identifies electronic cam and internal synchronous operation as additional integrated capabilities.
QA & Live Testing SOP
Step 1 — Exact Identity Check
Before energization, record:
- MDX61B0015-5A3-4-0T
- SEW part number 08279756
- MOVIDRIVE B family
- Size 1
- Technology/application version
- Option-card configuration
- Firmware/version information
Do not treat MDX61B0015-5A3-4-00 as automatically interchangeable with the -0T version.
Step 2 — Visual Inspection
Inspect the enclosure, cooling surfaces, terminal blocks, DC-link area, fan, control board, option slots, connectors, and grounding points.
Look for:
- Burn marks
- DC-link capacitor leakage or swelling
- Corrosion
- Contaminated cooling channels
- Damaged terminals
- Cracked connectors
- Previous repair evidence
- Missing covers or hardware
Step 3 — Power-Up Test
Use an appropriately protected test panel with the correct three-phase supply.
Confirm:
- Normal initialization
- Display/keypad operation
- No immediate hardware fault
- Correct DC-link charging
- Cooling-fan operation where applicable
- No abnormal current draw
Step 4 — Motor Test
Connect a compatible motor and appropriate feedback arrangement if the test configuration uses closed-loop control.
Verify:
- Drive-to-motor communication
- Motor identification/configuration
- Direction
- Low-speed operation
- Acceleration/deceleration
- Current behavior
- Fault handling
A successful display startup is not sufficient acceptance evidence for an industrial drive.
Step 5 — Technology-Function Verification
Where the required test equipment permits, verify the application functions associated with the technology version.
For a machine using synchronized motion, specifically verify the relevant synchronization and electronic-cam functions rather than testing only basic speed control. The -0T technology version is documented with these additional application capabilities.
Step 6 — Packaging
Use ESD-conscious handling for the control electronics. Protect terminal blocks, keypad/display surfaces, connectors, and cooling components against mechanical impact.
Field Engineer’s Pitfall Guide
❗ Do not substitute the standard -00 version without checking the machine application.
SEW explicitly distinguishes MDX61B0015-5A3-4-0T as an application/technology version. The technology version includes additional application functionality.
❗ Do not size the drive from motor kW alone.
The documented output rating is 4.0 A. Motor full-load current, overload requirements, control method, acceleration profile, and application duty must all be checked before approving a replacement.
❗ Check option cards and firmware before commissioning.
MOVIDRIVE B installations can depend on the installed option hardware and configured application functions. A replacement basic drive may power up normally while still being unsuitable for the machine.
❗ IP20 means this is cabinet-mounted equipment.
Do not treat the as a standalone field-enclosure drive. The installation needs appropriate electrical enclosure, cooling, clearances, grounding, and protection.
Intent-Driven FAQ
Q1. What is the ?
It is a SEW-EURODRIVE MOVIDRIVE B application/technology inverter, size 1, intended for industrial motor-control applications.
Q2. What is the rated motor power?
The 0015 configuration is rated for 1.5 kW under the standard constant-load recommendation. SEW also lists a higher motor-power recommendation for variable-torque or constant-load applications without overload reserve, so application duty must be checked.
Q3. What input voltage does it use?
The drive accepts 3 × AC 380–500 V, with a 50–60 Hz ±5% line-frequency range.
Q4. What is the output current?
The rated output current is 4.0 A.
Q5. What is the difference between and MDX61B0015-5A3-4-00?
The -0T designation identifies the MDX61B technology/application version. SEW documentation lists the -00 unit as the standard design and the -0T unit as the application version.
Q6. What motor-control methods are supported?
The MOVIDRIVE B platform supports U/f, VFC, CFC, and Servo control methods. The exact available functions depend on the drive configuration and application.
Q7. What is the SEW part number?
The exact technology-version part number is 08279756.
Procurement Note
For an exact replacement, specify , not simply “MDX61B 1.5 kW.” The -0T technology designation and option configuration are part of the engineering identity of the drive and should be checked against the existing machine before purchase.
