With the single stitch / full stitch function, it is possible to enable the execution of a stitch though pedal forwards actuation.
For this it is necessary to move the pedal forward only far enough so that the percentage portion (e.g., 40%) of the maximum
possible pedal travel (100%) set by the parameter 042, is not exceeded.
The execution is done as single stitch (Parameter 041 = 1) or full stitch (Parameter 041 =2)
If the travel set with parameter 042 is exceeded within the time set with parameter 051, the drive runs with the speed
specified by the respective pedal setting, even when under the threshold.
First after pedal 0-position can the special pedal function be actuated again.
The single/full stitch is executed in the speed set with parameter 122. To ensure that only a single stitch is executed,
the setting 300 rpm must not be exceeded.
041 =0
Special pedal function Off
041 =1
Single stitch:
The performs one rotation from position 1 to position 1. If it is standing in position 2, it runs to
position 1 the first time and then each time from position 1 to position 1.
041 =2
Full stitch:
The drive executes a complete rotation corresponding to its starting position.
7.30 Signal “Machine Running“
Function
Parameters
Mode "machine running"
Switch-off delay for signal "machine running"
(LSG)
(t05)
155
156
Set activation of signal “machine running” using parameters 155/156 .
155 =0
Signal "machine running" Off.
155 =1
Signal "machine running" will be issued whenever the drive is running.
155 =2
The signal "machine running" will be issued whenever the speed is higher than 3000 RPM
155 =3
Signal "machine running" will be issued whenever the pedal is not in position 0 or neutral.
155 =4
Signal "machine running" will be issued only after motor synchronization (one rotation at
positioning speed after power On).
156
Delay of switch-off time.
7.31 Signal Output Position 1
 Transistor output with open collector (max. +40 V, I
max
10 mA)
 Signal whenever the needle is in the slot between position 1 and 1A
 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
7.32 Signal Output Position 2
 Logic level output (+5 V, I
max
5 mA)
 Signal whenever the needle is in the slot between position 2 and 2A
 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 B18/9
7.33 Signal Output 512 Impulses per Rotation
 Logic level output (+5 V, I
max
5 mA)
 Signal whenever a generator slot of the position transmitter is sensed
 512 impulses per rotation of the handwheel
