When I was turning the spindle at 300 rpm today, in one of the short moments the alarm didn't trip I could notice the spindle was a little weird, like it couldn't kept the 300 rpm, and tried to stop, a few seconds later the alarm tripped again. Sometimes I can use it with no problems, but then again the alarm. I don't know if the pulse generator is inside the motor, because there's a timing pulley driving what I believe is a tachometer just over the spindle. This is what the lathe uses for threading and measuring spindle speed. > abit more info might help alot more in this error state. does it happen > when you turn the main power on? or when you release the machine from > estop? In general the alarm showed at the moment you turn on the machine, but this time it happened even after I started to work. -- *Leonardo Marsaglia*. ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
