Voltage callout of 200/1/60

[rslaback]

I noticed this voltage spec on a piece of automation equipment tonight. Am I correct in assuming that since we are looking at 200 and not 220/240 that this equipment is expected to be wired in using a wild leg of a 240V 3phase?

Possibly equipment of Japanese origin.

You may need a buck-boost xformer if it truly is 200v.

A single leg of 480Y system to neutral will provide 277v. That won't work.

Post the equipment specs. It could be a typo.

THIS ^ x2…………… 200 volts is a common voltage in Japan.

Equipment for 208v service is commonly rated at 200v. Using two lines of a three phase service gives you single phase.

Negative on that. If it is truly 208 equipment, that would be the rating or more typically 208/240. 200/1/60 is for sure Western Japan spec.

Now, running that equipment could very well work at 208 supply. Well within +/- 10% which is typical on industrial equipment.

 

[rslaback]

It is indeed a Japanese robot. In their power spec is the 200 a single hot to ground/neutral or 2 hots 180 degrees out of phase?

 

[manwithtools]

200V in Japan is line to line. We would frequently run Japanese robots on 208V three phase using two legs line to line. Check the spec on the robot, betting they allow +/- 10%. Is it Fanuc, Kawasaki, Epson?

no. no equipment is ever spec'd to run on a wild leg of a 240D.

motors rated to run on 208Y systems will have their voltage listed as 200v

or youll see 200/230/460

 

[wyliesdiesels]

If it is truly 208 equipment, that would be the rating or more typically 208/240.

guess youve never seen a motor nameplate thats listed for 200/230/460v, 200v being the rating for 208Y service

you could run it on a 208Y service. line to line is 208v 1Ø 60hz

I've seen plenty that list 208/230/460. But you all like to argue that it's 240 and 480, so...

Yushin

Wiki states Japan uses 100/200v split phase similar to the US 120/240vac.

I would assume the center tap is the neutral and bonded to ground as well.

What voltage do you have available: 208, 240, 480?

 

[Norcal]

200 volts is the rated voltage of equipment intended to be used with a 208V supply. I have a couple of Rockwell machines with 200V 3Ø motors dating back to the early 1970's, both the shaper & 7" grinder were former school machines & they both run off a 240V 1Ø supply with VFD's.

 

[manwithtools]

One thing to remember in this instance, the nameplate is a Machine Name Plate, not a single motor nameplate. As a result it should specify the following:

• Model Number
• Serial Number
• Manufacturing Date (MFG)
• Program No. (if applicable)
• Electrical Specifications: Rated voltage, number of phases, frequency, and full-load current (FLA)

OP, I'd call the tech support number for Yushin and inquire about your particular robot if you don't have the manual which should show the electrical connections and voltage tolerance.

I dont think anyone here has ever argued that motor nameplate ratings are 240 and 480v. motors have always been rated for less voltage than the system voltage. youre mixing up topics

I've hooked up a pretty fair number of 3Ø 200 volt motors to 208 volt systems.

The smaller ones are 3 lead, larger ones usually have 6 leads and are suitable for Y-∆ starting.

Have you seen my keys? Been carrying this for decades.

VERY TRUE ^ ….. I was not going to post a map of Japan showing locations of areas that I could not pronounce.
There are maps (on the net) of ALL countries that show transmission voltages so just look up the area and you will see the voltages.

BTW! Thanks for being the " Official GJ Geographic Police Officer"

 

[TRWham]

Japan has both 50 Hz (east) and 60 Hz (west) service depending on location. I understand this is because both US and European equipment were used to rebuild after war.

 

[mike93lx]

200v is common in all of Japan. It's the frequency that changes

 

[manwithtools]

No, all of Japan is 200 volts. It's the frequency that is different (West vs East).

You think they have a movie over there where the guy says "50-Herutsu demo 60-herutsu demo, hitsuyōnara nandemoī"?
