New Start Energy

VSD and VFD repair engineers across the UK.

Independent VSD and VFD fault assessment, workshop repair, parameter recovery, retrofit planning, installation and commissioning across the UK.

A fault code starts the investigation.

First, NSE reviews the equipment, application, operating risk and required timescale.

Information to send

Next, send the full fault code, drive and motor nameplates, application details, photographs and any available parameter backup.

Choose the safest practical route.

NSE then selects bench assessment, on-site repair, replacement or upgrade from the evidence, risk and parts availability.

Discuss this requirement with NSE.

Finally, share the equipment, application, operating risk and timescale. The engineering team can then identify the right next action.

VSD repair with a route back to service

A useful repair decision starts with the application, failure evidence and condition of the complete drive, not just the visibly damaged component.

Initial assessment

Confirm type code, rating, application, fault history, contamination, cooling and visible damage.

Component and board repair

NSE assesses power-stage, control-board, fan, capacitor, power-supply and ancillary defects. We then repair them where technically sound.

In-house testing

After repair, NSE electrically checks and functionally tests the equipment before recommissioning.

Parameter and software recovery

Where possible, NSE preserves or reconstructs available backups, option-card settings, motor data and application parameters.

Site commissioning

Next, NSE proves the drive with its motor, controls, process and safety arrangements.

When repair is not the answer

However, condition, obsolescence or risk may make repair unsuitable. In that case, NSE defines hire, replacement or engineered upgrade options.

Repair, prove, learn

The completed work should explain the likely cause, confirm the recovery, and identify any cooling, supply, motor or process issue that could cause a repeat failure.

Workshop capability

Component-level assessment backed by functional testing.

Drives, soft starters, power supplies, HMIs, PLC hardware, PCBs and selected control assemblies.

A practical repair decision: inspection, cleaning, component replacement, cooling service, parameter recovery and functional testing are agreed from the evidence and available parts.

Practical answers before you enquire.

Can a variable speed drive be repaired instead of replaced?

Often, but the decision depends on fault evidence, age, condition, parts availability, application risk and recovery time. NSE compares repair, replacement and temporary-hire routes.

What information helps with a repair assessment?

Send the manufacturer, complete model code, serial number, motor rating, supply voltage, fault message, application, photographs, available backup, postcode and timescale.

Does a VSD fault code prove the drive has failed?

No. A trip can be caused by the supply, motor, cabling, cooling, control signals, communications or process as well as the drive itself.
