Description
This function setting number is enabled when the sewing machine is operated with the foot
pedal (except for the full automatic mode). It is used for setting whether or not the presser foot
is automatically lifted when the foot pedal is returned to its neutral position. (0: OFF / 1: ON)
It is possible to select the type of presser foot lifting operation to be carried out when the back
part of the foot pedal is fully depressed or depressed by half of its depressing depth.
(0: Lifting the presser foot by depressing the back part of pedal by half-depth or by fully de-
pressing the back part of pedal / 1: Lifting of the presser foot is OFF / 2: Lifting the presser foot
by fully depressing the back part of pedal)
This function setting number is enabled when the function setting number P066 is set to "1:
Front lifter" or "3: Front and rear lifters". It is used for setting the time that elapses from lifting to
lowering of the presser foot. (Unit: ms)
This function setting number is enabled when the function setting number P066 is set to "2:
Rear lifter" or "3: Front and rear lifters". It is used for setting the delay time that elapses before
the presser foot lifting operation starts. (Unit: ms)
The presser foot lifting time should be entered when the solenoid valve is used. It is an extend-
ed parameter for future use. (Not used)
This function setting number is used for setting the time during which the presser foot lifter is
held in the ON state. (Unit: s)
It is possible to adjust the output intensity of the front sensor (light projecting side). (Unit: %)
* This parameter cannot be changed to the initial value that has been factory-set at the time of
shipment.
It is possible to adjust the output intensity of the intermediate sensor (light projecting side).
(Unit: %)
* This parameter cannot be changed to the initial value that has been factory-set at the time of
shipment.
This function setting number is enabled only in the case "DD23" is selected with the function
setting number "P125 Model selection".
It is possible to adjust the output intensity of the rear sensor (light projecting side). (Unit: %)
* This parameter cannot be changed to the initial value that has been factory-set at the time of
shipment.
This is the threshold of detecting the presence / absence of the material with the front sensor.
* This parameter cannot be changed to the initial value that has been factory-set at the time of
shipment.
This is the threshold of detecting the presence / absence of the material with the intermediate
sensor.
* This parameter cannot be changed to the initial value that has been factory-set at the time of
shipment.
This function setting number is enabled only in the case "DD23" is selected with the function
setting number "P125 Model selection".
This is the threshold of detecting the presence / absence of the material with the rear sensor.
* This parameter cannot be changed to the initial value that has been factory-set at the time of
shipment.
The correction value set with this function setting number applies to the threshold of detecting
in the case "0: Transparent fabric" is selected with the function setting number P088.
