sorry for my english (I'm from Italy) Last week, one of my customers asked me to retrofit an old milling machine with servo drives problems. Motors are AEG Gettys (M235-Y60A-900R) drived by Gould CLX A242 drives. I suppose they are DC motors/drives but I can not find any information or datasheets about them. I need, al least, to change drives and CNC. Could you suggest how find these information and, if you know Gould/Gettys product, sone valid substitution?
