New purchase spindle and VFD

Hey Tammy,

@Briantammy

I know we will need to purchase a VFD separately, does anyone have suggestions?

@Aiph5u

I would always recommend a VFD that has Sensorless Vector Control which is the case e.g. with the Hitachi WJ200, the Omron MX2, the Hitachi S1, and the Invertek E-3, and with many serious VFDs more.

If you choose the Hitachi WJ200 or the Omron MX2, which are excellent VFDs, you got to know that they are both practically identical. All the settings and options are identical and also the manuals have the same content (with extremely little exceptions) (Omron MX2 User’s Manual, Hitachi WJ200 User’s Manual).

The right model for single-phase 200-240 V input for driving a 2.2 kW motor is called either

• Omron 3G3MX2-AB022-E

and the WJ200 equivalent is called

• Hitachi WJ200-022SF

Be careful to choose the right model if you have split-phase electricity (240 V), since you got to buy these models which receive their power over one single phase.

I would always avoid considering 110 V VFDs/spindles except if you stay with 0.75 kW mechanical motor output at maximum, because with higher power, with 100 V class you need too big wires/fuses. In the U.S. you usually have split-phase electricity which means you can use a 240 V outlet (e.g. a NEMA 6 or NEMA 14) for higher power devices like VFDs/spindles.

Be aware that when you buy a spindle, …

on chinese spindles, the power rating is often wrong.
