Efka variostop motor and motor control box

Description

Efka variostop motor and motor control box.
This is from a used industrial Yamato coverstitch machine. I now use the machine for personal use and have converted the machine to a 110 servo motor and hand controls.
I’ve never used the motor or controller, sewing machine tech told me the motor and controls worked perfectly. I did not have a 220 service to try out the machine.
