(n2) Pedal completely
Function
with
or
without
control panel
Parameter
Selectable pedal functions
(-Pd)
019
The effect of pedal actuation on the drive functions can be set using parameter
019
:
019 = 0
Pedal in pos. -1 blocked in the seam. But with pedal in pos. -2 sewing foot lifting is possible in the
seam (function active whenever the light barrier is On).
019 = 1
With pedal in pos. -1 sewing foot lifting is blocked in the seam.
019 = 2
With pedal in pos. -2 thread trimming is blocked (function active whenever the light barrier is On).
019 = 3
The functions “pedal in pos. –1” and “pedal in pos. –2” are active.
019 = 4
The functions “pedal in pos. –1” and “pedal in pos. –2” are blocked in the seam (function active
whenever the light barrier is On).
Function
with
or
without
control panel
Parameter
Speed stage graduation
(nSt)
019
The pedal characteristics (speed change from stage to stage) can be varied.
Possible characteristic curves:
- linear
-
progressive
-
highly progressive
7.25.2 Analog actuator
Function
with
or
without
control panel
Parameter
Characteristic of the "analog pedal"
(APd)
026
The effect of pedal actuation on the drive functions can be set using parameter
026
:
026
= 0
Analog function off
026
= 1
