Parameter 190 = 4: Sequence with pedal in position –2 / no unlocking of the chain if seam end with light barrier,
cutting and run-out stitches is set:
!
Press pedal to position –2
!
Run at positioning speed to position 1
!
Sequence of reversing angle at positioning speed after a switch-on delay that can be set
!
No unlocking of the chain at the seam end with light barrier
!
Reverse motor rotation is suppressed when the drive stops. The signals “blow fabric onto
stack”, M2 and “sewing foot lift” will be issued.
