(NOTE 23) Setting is enabled when Function No. 63 is set to “1”.
(NOTE 24) Setting is enabled when Function No. 22 or No. 26 is set to “1”.
(NOTE 25) Setting is enabled when Function No. 68 is set to “1”. The stopping position is the angle after the need up signal
turns on.
(NOTE 26) Setting is enabled when Function No. 68 is set to “1”. The reverse feed mechanism switches at the stopping
position.
When the stopping time has elapsed, the sewing machine restarts automatically.

・
If the values are set to values that are less than the initial value (- direction), the quick reverse solenoid on/off timing
becomes faster. If the seam length immediately before switching occurs is short, change the setting to a value in the -
direction.
・
If the values are set to values that are greater than the initial value (+ direction), the quick reverse solenoid on/off timing
becomes slower. If the seam length immediately after switching occurs is short, change the setting to a value in the +
direction.
