ECOVARIO 414AN-BV-000-000 Servo Amplifier Drive

Description

Product Introduction & Engineering Value

The 414AN-BV-000-000 is designed to sit between a motion controller and servo motor, handling the power-stage functions required for controlled motor operation. Its published specifications identify a 7.1 A rating, 10 A RMS figure, 230 VRMS motor supply, 24 VDC control supply, and IP20 enclosure.

For maintenance teams, the key issue is replacement compatibility rather than simply finding another ECOVARIO drive. Motor type, feedback arrangement, controller interface, operating parameters, and the exact ECOVARIO configuration should be compared before commissioning. The part is also listed as discontinued by the manufacturer, making verified surplus or professionally refurbished inventory particularly relevant for legacy machines.

Technical Specifications

The 7.1 A, 10 A RMS, 230 VRMS, 24 VDC, 40°C, and IP20 values above are specifically reported for this part number by Radwell.

Interface and Motor Compatibility

Some third-party descriptions attribute a broad interface set to the ECOVARIO 414 family, including EtherCAT, CANopen, PROFIBUS, PROFINET, RS232, RS485, and Ethernet, and describe support for several motor technologies. These claims are not sufficiently specific to the 414AN-BV-000-000 ordering code to use as a guaranteed procurement specification. Confirm the actual interface and motor-feedback configuration from the unit nameplate, manual, or machine documentation before substitution.

Field Application & the “Trench” Experience

A typical legacy-machine problem starts with a servo axis that begins faulting during acceleration. The motor itself checks out. The feedback cable tests correctly. A replacement controller does not solve the problem. Eventually, the drive is found to have an intermittent power-stage fault.

With an older ECOVARIO installation, the first maintenance priority should be identifying the exact drive configuration. Installing another 414-series amplifier without checking the motor data and stored parameters can produce a drive that powers up normally but cannot correctly control the original axis.

The 414AN-BV-000-000 has been listed in the industrial replacement market as a servo drive and has documented repair history, making it a realistic candidate for legacy-machine restoration rather than a current-generation motion-system upgrade.

Specific application scenarios

Precision positioning equipment
Single-axis motion control where repeatable acceleration, speed, and positioning are required.

Semiconductor and electronics machinery
Servo-controlled stages, handling mechanisms, and positioning axes in older production equipment.

Machine-tool auxiliary axes
Rotary or linear positioning mechanisms where the existing control architecture was engineered around an ECOVARIO drive.

Legacy automation retrofit
Replacement of a failed servo amplifier without redesigning the complete motion-control system.

Transparency SOP: QA & Testing

A meaningful test of this drive should cover more than a visual inspection.

1. Identity verification
Confirm the complete 414AN-BV-000-000 designation and photograph the nameplate before testing.

2. Physical inspection
Inspect the enclosure, terminals, connectors, cooling surfaces, PCB condition, and signs of overheating.

3. Power-stage check
Test for abnormal resistance or short conditions before applying power.

4. Control-power test
Verify correct 24 VDC control supply behavior and startup response.

5. Motor simulation / test motor
Where suitable equipment is available, operate the amplifier with a compatible motor and feedback arrangement.

6. Current and fault monitoring
Check idle current, acceleration response, fault codes, and thermal behavior.

7. Final functional report
Record the part number, serial number, test configuration, operating results, and any replaced components.

For refurbished inventory, distinguish clearly between bench-tested, load-tested, and machine-tested. Those are not equivalent levels of verification.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Assuming 414-series drives are interchangeable.

Do not substitute based only on the ECOVARIO 414 family name. The complete ordering code should match. A similar enclosure does not guarantee identical power ratings, feedback interfaces, or control functions.

⚠️ Trap #2 — Forgetting the motor data.

A replacement amplifier may power up perfectly while still being incorrectly configured for the connected motor. Verify motor current, voltage, feedback type, acceleration limits, and controller parameters before enabling the axis.

⚠️ Trap #3 — Ignoring the discontinued status.

Radwell explicitly identifies the 414AN-BV-000-000 as discontinued by the manufacturer. That means procurement should focus on traceable remaining inventory, repair capability, and long-term spare strategy rather than assuming normal OEM availability.

PRO TIP: If this drive is supporting a production-critical axis, buy the replacement before the installed unit fails completely. For discontinued servo hardware, an unexpected failure can turn a routine drive replacement into a machine-level recovery project.

Dynamic FAQ

What is ECOVARIO 414AN-BV-000-000?

It is a Jenaer Antriebstechnik ECOVARIO servo amplifier / servo drive intended for single-axis motion control.

What is the current rating?

The published specification lists 7.1 A, with a 10 A RMS current figure.

What motor voltage is specified?

The available specification identifies 230 VRMS. The exact motor and feedback configuration should still be verified against the installed machine.

Is this ECOVARIO drive discontinued?

Yes. Radwell explicitly lists 414AN-BV-000-000 as discontinued by the manufacturer.

Is New Surplus the same as factory-new OEM stock?

No. New Surplus normally means unused inventory held outside the manufacturer’s current normal distribution channel. For a discontinued drive, request photographs of the actual unit, complete nameplate information, serial number, packaging condition, and available functional-test records.

Can a refurbished unit be used as a direct replacement?

Potentially, provided the exact part number and machine configuration match. The drive should be functionally tested, and the replacement should be commissioned using the original motor, feedback, and controller parameters rather than assuming factory defaults are correct.

What warranty should I request?

Warranty is supplier-specific. Current service providers list their own warranty terms; for example, Lektronix states a 12-month warranty for its repair and supplied replacement service for this model. That is a supplier warranty, not proof of an OEM factory warranty.
