Temporarily disable Efka EPS?

[JSLeathercraft]

Hey all.

I've been toying with the idea of trying my Ferdco Pro 2000 with Efka 1600 Vario DC without the EPS.  Is it as simple as temporarily unplugging the sensor from the controller or will I have to do some crazy re-calibrating if I want to plug it back in?  :-)

~Thanks!

I believe if you unplug the synchronizer, you'll get an error code E1. It won't hurt anything, it just won't sew.

The EPS is more of control box thing. The DC1600 is really the motor, which is often combined with the AB60D control box. The manual for the AB60D boggles the mind with nearly 300 parameters you can set. I glanced at it hoping to find some position sensor on/off parameter, but no such luck. 

My vintage Viking 6570 still has the best needle position control interface I've seen - a simple three-position switch with Up/Off/Down settings.

Uwe - forgot to mention control box is AB60A.

Thanks Eric....do you think it is impossible to use this without the EPS?

Looking at the Efka AB60A Manual  it appears you are out of luck. It boils down to "Thou shalt not use this setup without the positioner" unless I'm missing something.

The synchronizer is a critical component in your system. It tells your control box what's going on with your machine head which in turn tells the motor what to do. I have at least 20 different models of control boxes including Efka. None of them have the option of using the machine as if it had a clutch motor. The newer ones will control everything you can think of, but I suppose if you didn't want the control, you'd just use a clutch motor. I have lots of machines where I prefer a clutch. 

What's your reasoning for wanting this ability?

My rather simple JACK servos have an option for using them with and without NPS. I´m using them without as I´m rather slow sewing and simply don´t need it and they do not work in combination with a speed reducer. Just wanted to have this mentioned..

There are times when less is definitely more, no question. For my own use, I prefer a clutch so when I need to freewheel, I can put the motor in neutral and do what I want. It offers the least amount of resistance as well as letting me slip the clutch while applying pressure to the hand wheel. I have noticed in the factory that almost every operator that has sewn their finger did so as the needle positioned down.

Sewing fingers hurts and is not heathy in the long view

JSLEATHERCRAFT why don't you want to use the eps? Is it because you want the needle to stop wright before it enters the workpeace pherhaps?

If so, is it possible to offset the synchronizer? My old efka stops to high or to low when I turn the synchronizer. The bracket that holds the synchronizer in place is missing. So sometimes I have to re adjust it.

Maybe you could tune it the way you want it to stop.
