Yaskawa Servo drives?

I recall a couple comments in the last two weeks about the negative
aspects of Yaskawa servo drives and motors, Yaskawa in general etc
etc.

Id really like to know more about the plus's and negatives.
Particularly the Sigma series. A friend is considering swapping to the
Sigma drives/motors on his new line of machines as Baumuller is no
longer doing much inside the US. If this is a bad thing..he needs to
know ASAP.

I suggested originally going to Fanuc drives/motors..shrug. I think
the price scared him. No idea why thats not his first choice.

Any comments, suggestions etc would be greatly appreciated.

what cnc? if non fanuc, fanuc probably wont work anyway...the serial
encoders/amps are proprietary to fanuc.

If you need help/info on yaskawa, try calling a company in cleveland
ohio, called 'zesco' talk to tim sustersic. he sells/installs/setsup,
etc, yaskawa, delta-tau, and abb stuff, is extremely knowledgeable,
and will not give the normal sales crap you get from most people
involved with sales. he has been one of the most supportive
sales/engineering guys I've ever met & wont steer you wrong.

found a link to their website:
http://www.zescoinc.com/index.htm

good luck

Yaskawa has the biggest chunk of the market share in drives. And they have a
good product. We install them all the time. Tech support somethimes is a
little lacking though.

You never mentioned the application.

We have used this machining center about 5 yrs and this is the first drive
problem I'm aware of ... but their service dept sucks ... it seems if you
ask 3 different Yaskawa techs the same question you will get 3 different
answers.
The only thing all the techs agreed on was that Sigma 1 is not compatible
with Sigma 2 ... no one could tell me if the CNC cables were compatible or
would we need to get a new pinout from the Fagor if we went with Sigma 2.

Youy can use the same motor power cable but you will have to change the
encoder cable from motor to the drive. On CN1 to the control most of the IO
signals are the same (*Torque & speed monitor aren't available on the Sigma
II) But "probably " arent used by the control. You will also have to set the
parameters for the number of encoder pulses needed.

The upgrade is really straight forward.

PS Sigma I models are still in production & available.

I figger Kirk is just now starting to get his fingers loosened up. I
think he had a lot to do with these folks way way back.

They bought me off with an extra motor or two to make up for some
problems with their service. That says a little. . .at least they
acknowledged a problem and tried to address it.
