Hi everybody, I'm new to this forum. There seems to be some very knowlageable folks here.
I receintly moved my shop home and I,m still trying to get everything smoothed out. I,m running 2 Kiamura Mycenter 1"s and a 10 screw aircomp from a phase perfect 30 hp digital, with a 32volt buck on the single phase side. Phase perfect claims balanced voltage and delivers between the legs, however, as with RPC's it still has a hi manufactured leg when checking back to ground. My Fanuc OM controled My1 has no problem but the Yasnac I80 control ocationaly goes into a hi voltage input alarm on the spindle drive. It only does so during starting or stopping, never when cutting. I have the hi leg wired to T3. Kitamura says it it the hi leg causing the problem and recomended a that I install an isolation transformer, claiming that will calm down the hi leg while maintaining phase voltage balance. I have no problem doing so If that is the right way, however I am interested if there are any more simple, cheaper ways. I have a good friend who runs 3 Yasnac I80 controls from Rpc's and he has never had this problem. Opinions please.
Thanks, Matt
