Title: VFD
Post by: ADI on September 08, 2016, 12:43:29 PM

I just ordered the 107 from Steve last week for my Bridgeport it is a 2hp. I have access to a new 3hp VFD from a buddy here local. My question is would that be compatible with my Bridgeport? I just want to make sure there wouldn't be any type of tuning problems. Thanks

Using a 3 HP inverter to run a 2 HP spindle motor would be fine. If you want to
be fussy about it, you might check to see if the inverter has programmable
overload (of the motor current) sensing to protect the motor from overheating,
and set that for the smaller motor.

If it is a used inverter, you might start by resetting all parameters to factory
default in case the previous user had done any strange setups.

Also pay attention to the operational voltage. There are a lot of 460 VAC
industrial surplus inverters that are likely not suitable for use at home.
