Description
ON : Reverse-revolution operation is in the ON state
OFF : Reverse-revolution operation is in the OFF state
0: Operation is conducted at the first thread trimming speed.
10 to 500: The speed in the latter half is set when the thread trimming
speed is decreased in the latter half.
0 : Presser foot does not operate even when the back part of pedal is
depressed.
1 : Presser foot goes up to the 1st presser-foot lifting position when the
back part of pedal is depressed by half of the depth. It goes up to the
2nd presser-foot lifting position when the back part of the pedal is
further depressed.
2 : Presser foot does not operate even when the back part of pedal is
depressed. It goes up to the 2nd presser-foot lifting position when the
back part of the pedal is further depressed.
0 : Not detected
1 : Error is detected in the case the signal is LOW
2 : Error is detected in the case the signal is HIGH
