Delta VFD-EL-W AC Motor Drives

WOOLARS supplies Delta VFD-EL-W AC drives for machine projects and replacement inquiries. Before approving a cabinet layout, identify the exact frame and installation arrangement. A compact drive still needs the clearances and cooling conditions specified for its model.

VFD-EL-W model and frame lookup

The following 10 complete references are covered on this page. Use the frame to locate the applicable drawing, then check the full model code against the purchase specification.

Source: Delta VFD-EL-W user manual, sections 1-3 and 1-6. The manufacturer lists these references using W(-1) notation. This page retains the W codes assigned to it; keep any additional suffix shown on your actual nameplate when requesting a quote.

Three cabinet details to settle before ordering

1. Distinguish side-by-side from zero-stack installation

Delta’s manual permits zero-stack installation for frame B, but not frames A1 or A2. A frame-B arrangement therefore cannot be applied to an A1 drive simply because both belong to VFD-EL-W.

Mark the proposed mounting positions on a cabinet sketch. Include neighboring equipment and the space above and below each drive. Use the drawing and clearance table for that exact arrangement before fixing the backplate layout.

2. Use the temperature limit for the intended arrangement

For the listed frame-B models, Delta’s installation table gives 50°C without derating for single-drive and spaced side-by-side arrangements, versus 40°C for zero-stack installation. These are conditional limits, not permission to use every layout at the same temperature.

Include the expected temperature around the drive inside the cabinet in your inquiry. Record the enclosure ventilation and nearby heat sources, particularly if an existing cabinet is being expanded.

3. Record the cooling provision on VFD007EL21W

The instruction sheet gives a specific cooling-fan condition for VFD007EL21W. Without a cooling fan, its stated maximum ambient-temperature limits decrease by 10°C. Confirm the actual fan provision rather than applying a general series temperature figure.

For a replacement, send a clear photograph of the installed drive and available airflow space. Identify any proposed change to the fan arrangement for review.

What to include in a VFD-EL-W inquiry

Send WOOLARS the complete model, quantity and destination using Get A Quote or Live Chat. For a new Delta VFD-EL-W inverter installation, add the supply, motor nameplate and cabinet sketch. For a replacement Delta VFD-EL-W AC drive, include the existing nameplate and any accessories to retain or replace.

A frame match helps locate an installation drawing. Electrical ratings, control requirements and any alternative model still need a separate check.
