Have a chance to get a Mits 2KW servo with the super encoder on it. Was thinking of using it for a servo spindle. Problem is it has a brake on. Is it possible to remove the brake or will the servo have a longer shaft than usual to accomadate the brake. If it can be removed will the encoder need realigning. Presuming the encoder is not pinned for location.

Thanks John

You could remove the brake spring and pad, if it is that design.
All the Mits. encoders I have encountered on AC servo's have a keyed coupling.
This is in order to change an encoder in the field.
Some times a spindle brake is handy, you can set it up automatic or manual usually.
e.g. energise in auto when a M3/M4 is issued.

Thanks Nosmoking that might work. Was  worried about disturbing the encoder but if it's keyed that would be good.

I was thinking the break would be fine if it disabled on power up but as it's just a holding break I thought it might be damaged if I had to hit power stop at the full 3000rpm!

Plus putting tools in might be a problem or if I needed to rotate the spindle to check inserts.

Sounds doable though.

Quick question on the Galil ICM. I have a ICM1900/amp, is this the older version of the ICM2900 or something different?

Not sure what the "amp" refers too.

Thanks, John

The /Amp is an on board feature of included servo drives (amps), the only problem is they are usually rated for Galil supplied brushed motors.
So you have to use other  motors within these specs.
Galil typically have used A-M-C drives, just relabled, the /AMP usually uses these.

Ok thanks. All there seems to be on the unit is rows of terminals and one connector for the Galil 100 pin cable from the motion card.
There are labels XYZ and W but no power conectors for motors.

Usually the /amp version has power connectors depending on how many drives are included, (up to four).
If there are drives, you should be able to see them under the board.

re the 2kw servo. is it definately the s encoder and not the ose encoder?  i have one here with ose encoder which is 1 million counts/rev, but cant find a drive for it.

i have new 2kw j2s drives and motors here if you want to spend money...lol

beware as well. the bigger drives require 3 phase @ 220 volts (not 380v as we have in the uk) so you either require 3 phase tansformer or a 4series drive for our voltage.
you can run up to 750 watts off single phase ok
if its not broken yet, fit more gadgets!

Yes it's an S encoder. Has the blue S sticker on the back. Noticed the Mits MR-J2S-350A 3.5KW will accept single or 3 phase.
