4.4 Electromagnet performance adjustment
According to the typical configuration, parameters of 260 to 1, showed that the No.
1 electromagnets are set to cut the line electromagnet, the No. 1 electromagnet set
parameter 270~273 is cutting line electromagnet set parameters. Parameters of 261 to 3,
showed that the No. 2 electromagnet is set to reverse stitching electromagnet, the No. 2
electromagnet set parameter 274~277 is reverse stitching electromagnet set parameters.
Parameters of 262 to 4, showed that the No. 3 electromagnets are set to the presser foot
lifting electromagnet, the electromagnet is No. 3 set parameter
278~27B is the presser foot lifting electromagnet set parameters.
· electromagnetic speed adjustment
If the solenoid pull slow, inadequate. Can increase the electromagnet full output time, such
as increase of parameter 270, which increases the shear line electromagnet full output time,
so as to improve the shear line pull speed, increased shear line. If the electromagnet voice
is too large, may be appropriate to reduce the output time.
· electromagnet easily fever
Can reduce the duty ratio, the appropriate chopper opening time parameters (such as
271) or reduce the closing time parameters (such as 272) increased (Note: if the opening
time of the solenoid pull state may lead to inadequate or even ahead of the release ratio
adjustment is too small,).
· the solenoid pull weakness, how to adjust the operating state dynamics (how to
increase the pull strength when state
Can increase the duty ratio, the appropriate chopper opening time parameters (such as 275)
increased, or the closing time parameters (such as 276) decreases (Note: if the opening
time ratio adjustment is too large, easy to make the electromagnet
heating)
