Efka Variostop 3-Phase motor spins backwards

[Uwe]

I'm working on an Adler 467-FA373 with an Efka Variostop control box and 220V 3-Phase motor.  Everything seems to work fine except the motor spins backwards!

I've looked through the Efka manuals, but found nothing about reversing the motor rotation. Before I change the wiring on the plug or motor itself to swap two of the three power leads  (the standard way to reverse a 3-phase motor), I wanted to check with the Efka experts here in case I'm missing something ("Hey just flip this switch!")

I'm a little concerned that if I change the wiring to suit my current 220V 3-phase power outlet at TechShop, that my potential customer will plug the machine into their 3-phase outlet and the motor will not spin in the right direction.

I'm attaching a few picture of the machine and the Efka bits.

I'm no expert on the machines but I have worked plenty of 3 phase. Swapping any two leads on the main power supply will reverse the direction. If it is for a client you may need to ask them if the motor spins the right direction at his place. If so (after repairs are made), swap the leads back before returning it.

Uwe, assuming you didn't buy it new, could the previous owner have done just that - reversed the leads?

Reverse any two of the hot leads. The customer will have to do the same.

I received the machine as part of a larger inventory, So I don't have any history for it other than that it once sewed La-Z-Boy brand reclining chairs. 

In the U.S. there are at least six different plugs in use for connecting 220V 3-Phase power, so it's quite likely that the plug was changed at some point to accommodate a certain wall outlet.

Good grief!! At least we only have one "standard" for 3-phase power.

[Uwe]

Not to worry, after January 20th the U.S. will standardize on a"T" shaped plug without ground and only a 50% chance of electrocuting yourself when you plug it in.

My machines are all wired to the L15-30R plugs. My power all comes from feed rails with trolleys connected to the female  plugs on SJ cords. I have gates in my feed rail so I can change motor rotation by taking the trolley out and just reversing it in the rail. If a gate isn't close, I just reverse two leads in the fuse box.

Thanks Eric, I was hoping you'd chime in!

What's the model number of the control box, this may help us locate an owners manual for you.  See attached image.
