11.42 Signal Output 512 Impulses per Rotation
!
Transistor output with open collector
!
Signal whenever a generator slot of the position transmitter is sensed
!
512 impulses per rotation of the handwheel
!
Independent of sewing, thus also when turning the handwheel manually
!
Suitable e. g. for the connection of a counter
!
An inverted signal is issued at socket ST2/22
11.43 Actuator
The commands for the sewing operation are input by means of the actuator, which is connected to the pedal. Instead of the
built-on actuator another actuator can also be connected to socket B80.

Parameter
Selectable pedal functions
(-Pd)
019
Parameter 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).
Parameter 019 = 1
With pedal in pos. -1 sewing foot lifting is blocked in the seam.
Parameter 019 = 2
With pedal in pos. -2 thread trimming is blocked (function active whenever the light barrier is On).
Parameter 019 = 3
The functions “pedal in pos. –1” and “pedal in pos. –2” are active.
Parameter 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).
