I have this VFD running a 1.5kw spindle on 220v. I'm not doing anything complicated, just hitting the run button and it takes about 20 seconds to spool up to 24K and about the same to stop rotating after hitting stop. this is a light spindle with a 1/4" router bit. I'd like to match a router spindle where it takes less then 5 seconds to do both.
I'm pretty sure this spindle can start a lot faster because when I change PD025 to one the spindle screams to 24000 in less then a second. the manual leaves clues about how these settings work but is not clear. I got the decel down to about 12 seconds, and have a resistor on P-Pr, but I don't think the resistor is doing anything.
Does anyone have recommend settings to start and stop this spindle under 5 seconds?
