The following functions are possible using parameters 293 and 294:
293/294 = 0
Input function blocked
293/294 = 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 preselected basic
position.
293/294 = 2
Needle up:
Upon pressing the key, the drive runs from position 1 to position 2.
293/294 = 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.
293/294 = 4
Full stitch:
Upon pressing the key, the drive performs a full rotation depending on the stop
position.
293/294 = 5
Needle to position 2:
If the drive is not in position 2, it runs to position 2 upon pressing the key.
293/294 = 6...12
No function
293/294 = 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 pressed down, and the drive runs with speed limitation (n10).
293/294 = 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.
293/294 = 15
Tape cutter or fast scissors (mode 6/7):
Upon pressing the key, the tape cutter will be enabled
for a preset time.
293/294 = 16
Intermediate backtack:
Upon pressing the key, the backtack will be enabled anywhere in the
seam and at standstill of the drive.
293/294 = 17
Backtack suppression / recall:
Upon pressing the key, the backtack will be suppressed or
recalled once.
293/294 = 18
No function
293/294 = 19
Reset bobbin thread monitor:
After inserting a full bobbin, the stitch counter is set to the value
determined by means of parameter 031.
11.36 Functioning of Handwheel when Pressing a Key
Function
with
or
without
control panel
Parameter
Selection of handwheel increments carried out when the key is pressed once
(ihr)
260
Speed for the handwheel
(nhr)
261
Delay time until the key is pressed down causing the handwheel to rotate continuously
(ihP)
262
The handwheel can be set in motion by pressing a key. Select the key by means of one of the parameters 240...249.
Parameters 240...249 = 20
Direction of rotation of the handwheel according to the setting of parameter 161.
Parameters 240...249 = 21
Direction of rotation of the handwheel opposite to that set by means of parameter 161.
Parameter 260
Selection of the number of increments to be performed after pressing a key.
Parameter 261
Setting the speed for the handwheel.
Parameter 262
Setting the delay time. When pressing the key briefly, i.e. no longer than the time set by
means of 262, the increments set by means of parameter 260 are performed at the speed set
by means of parameter 261. When keeping the key pressed down, the handwheel runs
continuously until the key is released at the speed set by means of parameter 261.
11.37 Speed Limitation by means of External Potentiometer
Function
with
or
without
control panel
Parameter
Speed limitation by means of external potentiometer (maximum value)
(toP)
124
Speed limitation by means of external potentiometer (minimum value)
(bot)
125
Function “speed limitation with external potentiometer”
(Pot)
126
A speed limitation can be set by means of external potentiometer using parameters 124 and 125. The external potentiometer
can be connected to sockets ST2/2, ST2/3 and ST2/4.
