I just completed installing a VFD to a table saw with a 3 ph. 3HP motor.
After a bit of tinkering with parameters, saw appears to run fine. But when I check amps it shows 3.6, whereas the motor is rated 7.4
It's an older saw and the nameplate doesn't have FLA, or LRA, just 7.4 Amp
I can't check it under load because owner is retooling cast iron top. I told owner I believe saw will run at or near
nameplate amps when it is being used to actually saw lumber, and not just spin the blade.
Would appreciate your educated opinions on this, thanks.
