Lenze EVF9328-EHV100 AC Drive – Obsolete EVF Series Spare Part

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Electrical parameters (rated power, input/output voltage, current rating) vary by sub-variant. Contact DriveKNMS with your full nameplate data for confirmation before ordering. No parameters are assumed or fabricated.

Solving the Discontinued Hardware Crisis

For plant managers operating under capital expenditure freezes or facing pressure to defer line modernization, the EVF9328-EHV100 represents a targeted, low-cost intervention. A single verified replacement unit — properly installed and commissioned — can extend the operational life of an existing drive system by 5 to 10 years. That window is sufficient to align a controlled modernization with a planned capital cycle, rather than forcing an emergency retrofit at the worst possible moment.

For plant engineers searching: how to extend Lenze EVF 9300 drive life, EVF series replacement without rewiring, keep legacy Lenze drive running, avoid PLC migration cost by replacing VFD — DriveKNMS specializes in sourcing exactly these components.

Condition & Reliability Assurance

Every EVF9328-EHV100 unit processed by DriveKNMS passes a structured 5-step quality assurance protocol before it is offered for sale:

Step 1 – Electrolytic Capacitor Assessment: DC bus capacitors and filter capacitors are inspected for physical swelling, leakage, and ESR degradation. Units with compromised capacitors are either recapped with equivalent-spec components or removed from saleable inventory.

Step 2 – Firmware Version Verification: The installed firmware version is documented and cross-referenced against known compatibility requirements for the EVF 9300 platform. Mismatched firmware is a common source of parameter restore failures after replacement.

Step 3 – Terminal and Pin Corrosion Inspection: All control terminals, power terminals, and communication interface pins are inspected under magnification for oxidation, corrosion, and mechanical damage.

Step 4 – Functional Power-On Test: Where test bench infrastructure permits, units are powered on and basic drive response is verified. Results are documented.

Step 5 – Packaging and ESD Protection: Units are packaged in anti-static materials with desiccant. Storage and shipping conditions are controlled to prevent moisture ingress.

Condition grades (New, Refurbished-Tested, Used-Tested) are disclosed at point of sale. No unit is represented as new unless it is confirmed factory-sealed.

Key Features for System Maintenance

The EVF9328-EHV100 is a direct drop-in replacement for the same model position within the EVF 9300 Series:

No rewiring required: Power and control terminal layouts are identical to the original installation. Physical mounting dimensions are unchanged.

No PLC reprogramming required: The replacement drive communicates over the same Lenze system bus protocol. Existing PLC logic, parameter sets, and communication addresses remain valid — provided firmware versions are compatible, which DriveKNMS verifies prior to shipment.

No engineering redesign: A qualified maintenance technician with the original parameter backup can restore the drive to service without engaging a systems integrator.

Cost avoidance: Avoiding a forced migration from the EVF platform to a current-generation drive family eliminates engineering costs, commissioning costs, and the risk of process disruption during changeover.

Q: Can you help me retrieve my original parameter set if I lost the backup?
A: DriveKNMS can advise on parameter recovery options. Contact our technical team with your application details.
