Reached The End Of My Rope With This

[Hockeymender]

I have a Consew 227-R-2 that has for a very long time been on an off the arm table with a speed reducer and a Goldstar GBSM550S servo motor with a needle positioner. I purchased a new table (same type just much nicer) and moved everything to the new table. When I get everything together, the needle positioner refuses to work. The motor stops when the pedal is released, but the machine runs till it has expended all its energy. I have tried different motors (have several of this type), syncronizers and control boxes, all with the same result. The only way the needle positioner will work is if I bypass the reducer and go motor to machine (which is to fast). Cannot figure out what happened between tables to produce this issue. Open to any ideas.

Is the pedal rod too short now?

No. Everything was sized according to the setup on the new table. Everything lines up correctly.

Joe, you are close to Toledo, give Bob a call at Toledo industrial sewing machines. Number is in the suppliers section. I am sure he can help you.

The only reason why the machine may keep spinning after you shut off the motor is that the brake clutch in the motor is not engaged.

Is the brake applied if you remove the rod connecting motor lever with the pedal?

The machine doesn't keep spinning after the motor is shut off. When the machine is in use and the pedal is released to its resting position, the machine continues to go till it runs out of its own energy. The lever on the control box is in the up position but there is no braking action. None of this occurs when the reducer is bypassed. Every function works exactly right with no reducer. All worked on the old table, this issue once everything was moved.

Go Blackhawks! Played in that organization once upon a time.

Sorry Bob.

Sounds like one of the V belts in the reducer is slipping?

That's what I thought. Tried several different belts in both positions and like everything else I tried, didn't make a difference.

If it all worked before, i.e. the only difference is the new table, then the logical thing is to put everything back as it was, on the old table, and see what happens. If you still have problems then it's obvious that you've changed something else in the process. If it works fine on the old table then obviously your new table has a curse on it.

I'm also at a loss to understand how it keeps running, if the motor has stopped.

[Constabulary]

I guess you mean when you step off the pedal the motor is still running and that spins the machine right?

Check if the plug of the needle positioner sensor is properly plugged in. I remember when I installed my 1st servo I had a similar problem.

Next thing I´d check it the sensor / magnet lever alignment in the accelerator unit - you probably have to adjust the internal lever a little bit.
