Ok, one last one then I'll leave you alone for a little while I swear.
How can I find out what the max RPM of the machine should be (belt/motor configuration or something I'm guessing) and then how do I match it up to what the machine thinks its doing.
Looking at the programs left in memory they bump around the speeds between 3 and 8k (that one might be a fluke) like they thought they meant something, but the machine currently thinks its maxing out at 2400. The VFD readout is stating Frequency Ref U1-01 = 207.00 hz (the vfd is a big white box with a JVOP-130U interface)
That seems like a logical max, but that spindle is really booking at the high end and I find it hard to believe its only doing 2k.
I think the Ad said 7K spindle but its been 4 months since then so the memory is fuzzy.
I sent a info request to milltronics with the serial number etc.
