It is to set the beginning strength of the presser foot solenoid.
It is to set the time period the highest electric current passes through the solenoid.

Setting
Value
[Contents] In cases of electric solenoids, set the beginning strength of the presser foot by
adjusting the time period high current flows through (Full on time).
[Caution]
If set too low, the solenoid may not operate, and when set too high, too much
electric current may overheat and damage the solenoid and fuse.
[Reference] The operation time and strength of the actuators (presser foot, trimmer, wiper)
which use the solenoid, can be adjusted by adjusting the electric current of the
solenoid. Full on time is the period when the solenoid’s electric current is at the
highest point.
highest electric current
0~t1 : Full On Time (Period of highest electric current)
0~t2 : Solenoid operation time
t1~t2 : Period when electric current flows from duty
∗Duty is the rate of time the signal light is lighted during a
period of time. For example, when the duty is 50%,
Ton and Toff are the same.
