Hey Christopher,
yes this looks like the correct variant Hitachi WJ200-022SF, which MikeH presented here, that also more forum members run (here, here) and which is identical to the Omron MX2 that I own.
Here you see my VFD’s nameplate, and below, Michael’s @MikeH nameplate:
Here you can also see that the Omron offers 580 Hz while the Hitachi only 400 Hz, but this only matters if you want to run spindles with more than 24,000 rpm (e.g. these ones). With 400 Hz, you can run the usual 24,000 rpm spindles.
I would look for the matching EMI filter and the brake resistor too.
-
As per the Omron MX2 manual, SECTION 5: Inverter System Accessories, for the 200 V class single-phase input 2.2 kW model, it is
- as braking resistor, for 3% braking duty, Part No. AX-REM00K2070-IE (70 Ω), and for 10% braking duty Part No. AX-REM00K4035-IE (35 Ω) (180 % braking torque),
- the EMI filter is Part No. AX-FIM1024-RE for the Rasmi brand and Part No. AX-FIM1024-SE-V1 for the Schaffner brand.
-
As per the Hitachi WJ200 User’s Manual,
- for the EMI filter, for the 200 V class single-phase input 2.2 kW model, it is on page D-2, Part No. FS24828-27-07 for the Schaffner brand, and
- as for the braking resistor, on page 5-2, the Part Nos. are SRB-xxx-x, JSB-xxx-x, HRB-x, NSRBx00-x, NJRB-xxx (see page 5-5, but page seems missing
)
These EMI filters match the Omron/Hitachi VFDs as they are “footprint” filters which means you can mount them on the back of the matching VFD model, between VFD and the mounting plate of your control cabinet. The VFD and the EMI filter are properly grounded this way. Of course you can also mount the EMI filter separately:
