There is a problem with the motor. Check your connections of wiring and such to make sure they are secure. The problem might be the brushes or might be the circuit board to the motor. Look for signs of damage or wear on that main circuit board. If found, replace the board. If the problem is not then resolved, you might contact Juki customer support. This is not an inexpensive machine. https://jukiamericas.com/pages/support
