Hello,
are an Italian boy and are looking desperately for help, I hope someone can help me.
I own a CNC lathe with Samsung PL25A samsung cnc, lathe l 'I used about two years ago and problems 0.
Yesterday I was working a post I get allarm 012 unit spindle motor .... I try to reset but the engine does not stop immediately.
I go to the electrical panel and hit reset on the inverter and the spindle stops, the inverter monitors the alarm was F100 (INVERTER OUTPUT CURRENT EXCEDEES THE VALUE )
I do not understand what might have happened, never had problems with the engine, I restarted the spindle several times and noticed that goes into alarm when I exceed 1000 rpm, at low rpm nn nothing happens.
In your dirt deposited in the channels of cooling of the engine can cause such alarm?
Instead of manual lathe, it shows me as an overcurrent alarm 012 on supply of 2.5V.
Where can I measure this overhang on the electrical system?

The inverter is a Yaskawa 626vm3

The rating plate of the motor:

Yaskawa UAASKA-15CZ3N
3 PHASE 4 POLES
15/11 KW
RATING 30MIN / CONT
RPM 400/4800
AMP 88/67


sorry for the English but I'm using google translator


thanks a lot
