The functions of the keys/switches connected to socket connectors ST2, B18 and B22 can be selected for
inputs in1...in13 using parameters

Input function blocked
1
Needle up/down:
Upon pressing the key, the drive runs from position 1 to position 2 or from position 2 to
position 1. If the drive is not in the stop position, it runs to the pre-selected basic position.
2
Needle up
Upon pressing the key, the drive runs from position 1 to position 2.
3
Single stitch (basting stitch):
Upon pressing the key, the drive performs one rotation from position 1 to
position 1. If the drive is in position 2, it runs to position 1 upon pressing the key and from position 1 to
position 1 each time the key is pressed again.
4
Full stitch:
Upon pressing the key, the drive performs a full rotation depending on the set stop position.
5
Needle to position 2:
If the drive is not in position 2, it runs to position 2 upon pressing the key. After
power On the drive runs until it has been synchronized.
6
Machine run blockage effective with open contact:
Upon opening the switch, the drive stops in the pre-
selected basic position.
7
Machine run blockage effective with closed contact:
Upon closing the switch, the drive stops in the pre-
selected basic position.
8
Machine run blockage effective with open contact (unpositioned):
Upon opening the switch, the drive
stops immediately unpositioned.
9
Machine run blockage effective with closed contact (unpositioned):
Upon closing the switch, the drive
stops immediately unpositioned.
10 Run at automatic speed (n12):
Upon pressing the key, the drive runs at automatic speed. The pedal is
not used. (This input function is inverted in mode 9.)
11 Run at limited speed (n12):
Upon pressing the key, the drive runs at limited speed (function of the key
according to setting of parameter
266
). The pedal must be pressed forward.
12 Sewing foot lifting with pedal in position 0 (neutral)
13 High lift for walking foot operational mode not stored:
The signal “high lift for walking foot” is issued as
long as the key is held down, and the drive runs with speed limitation (n10). Set parameter 137 to On.
14 High lift for walking foot operational mode stored (flip flop 1):
The signal “high lift for walking foot” is
issued upon briefly pressing the key, and the drive runs with speed limitation (n10). The operation is
disabled upon pressing the key again. Set parameter 137 to On.
15 No function
16 Intermediate backtack / intermediate stitch condensing:
Upon pressing the key, the backtack or stitch
condensing will be enabled anywhere in the seam and at standstill of the drive.
17 Stitch Regulator Suppression/Recall:
Upon pressing the key, the backtack or stitch condensing
operation will be suppressed or recalled once.
18 No function
19 Reset bobbin thread monitor:
After inserting a full bobbin, the stitch counter is set to the value
determined by means of parameter
031
.
20 Move to target position in direction of rotation:
Upon pressing the key, the drive runs in the direction of
rotation according to the setting of parameter
161
.
21 Move to target position against direction of rotation:
Upon pressing the key, the drive runs in the
opposite direction of rotation according to the setting of parameter
161
.
22 Speed limitation n11 (flip flop 2):
Upon pressing the key in the seam, the speed limitation n11 is enabled,
and a signal is issued at the output ST2/29. The speed limitation will be disabled upon pressing the key
again, and the signal at the output is no longer issued.
23 No function
24 Stop function:
For this function, the red key S8 is provided in the multiple-function key bar on the machine
head. However, any other input may also be programmed with this function. (see chapter Stop function)
25 Speed limitation with external potentiometer:
Upon pressing the key, the external speed limitation
becomes effective. Parameter
126
must be set at 2.
26 No function
27 No function
28 External light barrier:
In this mode it is possible to initiate the seam end using a key, not the light barrier.
But the light barrier function must be On.
29 No function
