    Shop argument! Must have metric ballscrew on cnc lathe to make metric threads?

    This is rather nonsensical reply. You can just as well say: "Consider the fact that a inch screw machine can not make an exact 1 in move. Why, because everything is done inside in counts (integers). 1in is 1.0000000000 so one can not hit it perfectly as the control cannot see partial counts...

    Phase Converter Help

    I disagree with other answer: I say go for it with your 7.5hp RPC and do not waste money on new/bigger one until you try your present one and prove it is too small. My reasoning is: 1) that machine nametag actually seems to show your "5HP" motor is really only 1.5HP and the 5hp shown is the...

    46" ballscrew, 5/8" dia, 1/4" lead - almost free?

    I have not sold a ballscrew in 20 years (semi-retired servo distributor here) so have no clue the value. I have been loading stuff up outside the warehouse to take to the metal shredders for the last year; this was in the batch so rusty. Came out of a linear slide (I have the aluminum housing...

    Reforming Capacitors For A V.F.D.

    Ya, it is all relative... We can spend well in excess of $1000 easily for new caps for large spindle VFDs so they ain't necessarily cheap... Getting to them generally is not a problem on VFD and servo drives as the bus terminals are generally readily accessable. If not, sending AC or DC...

    1hp VFD for a 1.5hp motor?

    Yes, this has been done and works. Strongly suggest against buying the chinese junk for many reasons. You shold be able to beat that price with Hitachi, Teco, etc. If you want a Teco, ask them.

    Likewise, more free time here; so I enjoyed reading your post and had to reply too! I supplied the servos and drives for all 3 of these machines you worked on. We used brushless Harowe size 11 resolvers in the back of the motors - geared to the motor shaft so 0.200" of slide motion = 1...

    Yes, wouild have been nice if it Farrand to encoder unit could be backfed! But alas, not in the cards. Besides, the Inductosyn is ua or milli amp level signals, not like resolvers. No one has ever needed a encoder or analog signal replacement for a resolver in the past I guess. We did for...

    Hahahaha! Knowing WHERE to smack it was worth its weight in gold! Friend and I developed an encoder to resolver converter a year ago; we use it to use encoders now to run into older controls and drives that required resolvers. No one else has such a thing.

    Howdy! How about this, reviving a thread from 2009! I have N350 manual but not N360, even tho we have at least 1 N360 still on the warehouse shelf. A friend asked me for a manual to help him with a problem and I am embarassed to not have one. Might you still have a N360 manual you could send?

    Fanuc AC spindle motor with Emerson SP unidrive?

    Baron, I would strongly recommend you ask Motion Guru for assistance and this retrofit will go as smoothly as possible... For instance, without accepting his expert advice, you will have a hard time figuring out the proper base speed VOLTAGE rating for this motor; Fanuc typically had very low...

    Sizing VFD for Yaskawa Spindle Motors

    With six gear ranges, you're 25 amp VFD will be fine. You will not need to watch the motor temperature, as you will not have /over 29 amps continuous available to harm it. Sent from my SM-G900V using Tapatalk
