Re: Spindle heats up
You have to set up the VFD for your spindle, would running it at 10 amp vs 5 on nameplate be a problem, yes. My guess you have already overheated the windings and its next stop could be the dump. Find your owners manual and set the parameters, or contact the people you purchased it from.
BTW is it air or water cooled and if water was it connected to same?
Running this spindle slower than 100 Hz can damage it and slower that 130 Hz if its air cooled will overheat it.
Mactec 54 can help you.
