(9)Holding time of lifting presser foot (Function setting No.47 T-FL)
Solenoid type presser foot lifter (No. 46 0) can adjust the holding time control of lifting presser foot.
This function automatically lowers the presser foot when the time set with the setting No. 47 has passed
after lifting the presser foot.
When the pneumatic type presser foot lifter (No. 46 1) is selected, the holding time control of lifting presser
foot is limitless regradless of the set value.
Setting range
10 to 600 sec <10 / sec>
(10) Compensation of timing of the actuator for reverse feed stitching (Function setting Nos.51
to 53 T-SON, T-SOFF, T-EOFF)
Actuator of SC-915 is the solenoid.
Actuator of SC-916 is the stepping motor.
When the normal and reverse feed stitches are not uniform under the automatic reverse feed stitching
action, this function can change the ON/OFF timing of the actuator for back tack and compensate the timing.
1) Compensation of on-timing of actuator for reverse feed stitching at the start of sewing (Function setting
No. 51)
On-timing of actuator for reverse feed stitching at the start of sewing can be compensated in the
increments of 10˚.
Adjusting range
– 36 to 36 <1/10˚>

2) Compensation of off-timing of actuator for reverse feed stitching at the start of sewing (Function setting
No. 52)
Off-timing of actuator for reverse feed stitching at the start of sewing can be compensated in the increments
of 10˚.
