Product Introduction
The Magnetek GPD506V-B004 is a general-purpose AC variable speed drive rated for 460 VAC, 3-phase input and a 5.1 A output across a 0–400 Hz frequency range. It’s part of the GPD-506 platform, cross-referenced directly to the Yaskawa CIMR-P5M41P51F, which tells you this drive shares its core design with Yaskawa’s industrial VFD line from that era.
This exact model shows up consistently across multiple industrial surplus and repair channels with matching electrical ratings, which is a decent trust signal on its own — GPD-506 drives from this generation are common enough that dedicated repair-and-exchange programs exist for them, so replacement parts and rebuild services aren’t hard to find if a unit does fail down the road.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Drive won’t power up, no display | Incoming 380–460 VAC power loss or blown input fuse | ✅ High | Measure input line voltage at the drive’s input terminals | Confirm incoming power before suspecting the drive itself |
| Motor won’t run despite drive showing “ready” | Wiring fault between drive output and motor, not a drive fault | ❌ Low | Check output terminal continuity and motor lead connections | Isolate motor wiring before condemning the drive |
| Drive trips on overcurrent fault | Motor load exceeds the 5.1 A output rating, or a motor-side short | ✅ Moderate | Measure actual motor current draw against the drive’s 5.1 A rating | If load consistently exceeds rating, this is a sizing mismatch, not necessarily a drive defect |
| Output frequency doesn’t match commanded speed | Parameter/configuration mismatch, not usually a hardware fault | ❌ Low | Check drive’s programmed frequency reference source and acceleration/deceleration settings | Review configuration parameters before assuming hardware failure |
| Drive runs but display shows intermittent fault codes | Loose control wiring or a cooling/thermal issue | ✅ Moderate | Inspect control terminal wiring; check for adequate ventilation/cooling around the drive | Address wiring and thermal environment before replacing the unit |
If you’re still stuck, send us the exact fault code shown on the drive’s display along with the motor nameplate data — that combination tells a repair tech quickly whether this is a drive-level issue or a motor/load mismatch.

Frequently Asked Questions (FAQ)
Is this actually a Magnetek product, or is it a rebadged Yaskawa drive?
Good question to ask before you buy. The GPD-506 platform cross-references directly to the Yaskawa CIMR-P5M41P51F, and one listing we found even lists Yaskawa as the underlying “make.” Magnetek marketed and sold this drive platform, but the core engineering traces back to Yaskawa — worth knowing if you’re hunting for compatible manuals or parameter sheets, since Yaskawa’s CIMR-P5 documentation may be easier to find than Magnetek-specific literature.
Can I get this repaired instead of replacing it outright?
Yes — there’s an established repair-and-exchange market for this exact model, which tells you it’s common enough that rebuild parts and expertise aren’t hard to come by. If your unit fails, a repair/exchange service is a real alternative to a full replacement, and worth comparing on cost and turnaround time.
Is this new or used, and does it matter for reliability?
Both circulate for this part number, often from the same reseller at different price points. New-in-box units obviously carry lower risk of hidden wear, but used-tested units from a reputable seller with a stated warranty are a reasonable option for a drive this common — just get the condition and test status in writing.
What motor size is this drive good for?
Match your motor’s full-load amp rating against this drive’s 5.1 A continuous output rating, with margin — don’t run it at the ragged edge of its rated output on a continuous-duty application. If your motor’s FLA is close to or above 5.1 A, you need a larger frame drive, not this one.
Can I hot-swap this drive while the motor is running?
No. Kill input power and allow the DC bus to fully discharge before disconnecting or connecting this unit. VFDs hold stored energy on the bus capacitors after power-down — treat that like a real hazard, not a formality.
Why do prices for the “same” unit vary so much between sellers?
Partly condition (new vs. used), partly warranty length, and partly how each reseller sources their stock. The specs themselves — 460 VAC, 5.1 A output, CIMR-P5M41P51F cross-reference — are consistent across every listing we checked, so the electrical identity of the part isn’t in question. The price spread is a seller/condition issue, not a sign you’re looking at different hardware.
