The pedal characteristics (speed change from stage to stage) can be varied.
Possible characteristic curves: - linear
- progressive
- highly progressive
6.33 Acoustic Signal
Functions Parameter
Acoustic signal when machine run blockage or thread monitor is On (AkS) 127
An acoustic signal which sounds in the following cases can be enabled using parameter 127:
Parameter 127 = 0 Acoustic signal Off.
Parameter 127 = 1 Acoustic signal from stop after execution of the stitches to pressing key 8.
Parameter 127 = 2 The drive stops after execution of the stitches. Sewing is possible up to the seam end. Then
the acoustic signal sounds until key 8 is pressed.
Parameter 127 = 3 The drive stops after execution of the stitches, and the acoustic signal sounds 5 times. Sewing
is possible up to the seam end. Then the acoustic signal sounds until key 8 is pressed.
