It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case)
Suggest you in the inverter power installed a frequency converter input filter, try it, feel a bit like electromagnetic interference caused by frequency converter mistakenly stop ah.
Has the frequency converter been used for a long time? The inverter power placed on the two day, and then open, put the line inside the head plug again, and then boot general can solve the problem, new don't try
