Programming of Seams
Um häufig vorkommende Nähabläufe komfortabel einstellen und abrufen bzw. verschiedene Nähte mit unterschiedlichen
Einstellungen aneinanderreihen zu können, ist die Naht-Programmierung möglich.
A maximum of 8 patterns with a total of 40 seams can be established.
Programming is possible only if a code number has not been input after powering on!
The functions “start backtack”, “end backtack”, “stitch counting”, “thread trimming” and “sewing foot lift” can
be assigned individually to each seam.
For all 8 patterns, different numbers of start and end backtacking stitches can be programmed.
The maximum number of stitches for the forward or backward section is limited to 15 stitches.
It is possible to “teach in” seams with stitch counting by executing the desired sections.

The angular positions necessary on the machine, e.g. for “needle down position” or “thread lever up position”, are stored in
the control as numerical or angular values. In order to establish a relationship between electrical position transmitter
information and actual mechanical position, a reference position is needed.
5.3.1 Setting the Reference Position
The angular positions necessary on the machine e.g. “needle down position“ or “thread lever up position“ are stored in the
control. A reference position is needed in order to establish a relationship between position transmitter information and
actual mechanical position.
The reference position must be set:
for initial operation
after replacing the position transmitter
after replacing the microprocessor
Reference position = Needle point at the height of the needle plate, from downward movement of the
needle in the direction of rotation of the motor shaft.
Note
If a different needle position (other than reference position) is set, the values of the signal and stop positions (Pos1 and
Pos2) preset by the manufacturer are no longer valid and must be reset.

EFKA DA82GA3312
The sewing foot pressure consists of a basic value generated by spring power and a value generated pneumatically. After
power On, the sewing foot always works at full pressure. The sewing foot pressure can be reduced by pressing the key
connected to socket D/4-15. The sewing foot pressure output is disabled. It is enabled by pressing the key again. The
reduced sewing foot pressure is indicated by a light emitting diode. At reduced sewing foot pressure the speed is limited
depending on parameter 146. Speed limitation DB2000 or DB3000 can be selected using parameter 146. Moreover, it is
possible to select inverted sewing foot pressure reduction. Normal sewing foot pressure can be enabled by pressing the key
again. The key can be pressed at any time except during automatic seams or seam sections. The sewing foot lift does not
have influence on the sewing foot pressure.

The start backtack starts by pressing the pedal forward at the beginning of the seam. From lifted sewing foot the backtack is
delayed by the time t3 (start delay after disabling the sewing foot lift signal). The start backtack is executed automatically
at speed n3. If softstart is running parallel, the respective lower speed is prevailing.
Whether or not an interruption of the start and end backtack is possible can be determined with parameter 284. It does not
work with the ornamental backtack.
Parameter 284 = ON
Backtack can be interrupted by pedal position 0 (neutral). A separate speed using parameter
125 is available for this purpose.
Parameter 284 = OFF
Automatic backtack cannot be interrupted
By pressing the pedal forward after an interrupted start backtack, the backtack can be continued; by half heelback (-1), the
the sewing foot can be lifted, or, by full heelback (-2), trimming without end backtack can be completed. The sewing foot is
not automatically lifted when interrupting the backtack.
The start backtack stitch length is set with the following parameter:
Parameter 137 = ON
Backtack is performed with normal stitch length.
Parameter 137 = OFF

The end backtack starts by heelback, in a seam with stitch counting at the end of counting, or, from the light barrier seam at
the end of the light barrier compensating stitches. The stitch regulator is immediately enabled from machine standstill.
After lowering the sewing foot, the switch-on point of the stitch regulator is delayed by the time t3 (start delay after
disabling the sewing foot lift signal). The first leading edge of position 1 counts as 0 stitch whenever the function is not
started in position 1. Counting and disabling the stitch regulator is synchronized to position 1. From full machine run, the
signal will be switched in only after having reached the end backtack speed n4 and synchronization to position 2.
Whether or not an interruption of the start and end backtack is possible can be determined with parameter 284. It does not

6.19.1 Manual High Lift for Walking Foot – Speed Limitation
The high lift during sewing can be set on a handwheel intended for this. The high lift shaft in the machine is hereby turned.
The position of the high lift shaft is queried by means of a turn switch, which limits the maximum machine speed to
DB3000 in position 1 and to DB2000 in position 2.
6.19.2 Maximum High Lift for Walking Foot by Using a Key
By pressing the key connected to socket A/7-33 or D/6-15 (parameter 149 = 1) or B/1-2, high lift for walking foot and a
light emitting diode are enabled. The maximum speed is limited to the high lift walking speed (DB2000). If the actual
speed is higher than the high lift walking speed, the drive slows down to high lift walking speed before the output “high lift
for walking foot“ is enabled. When high lift for walking foot is disabled, the speed limitation remains On for the time set
using parameter 152. 3 operational modes are possible: not stored, stored and not stored with a minimum number of
stitches.
6.19.3 High Lift for Walking Foot Operational Mode Not Stored
(Pa. 138 = OFF, Pa. 184 = 0)
By pressing the key “high lift for walking foot“, the output “high lift for walking foot“ is enabled depending on the actual
speed until the key is released.
6.19.4 High Lift for Walking Foot Operational Mode Stored (Pa. 138 = ON)
By pressing the key “high lift for walking foot“, the output “high lift for walking foot“ is enabled depending on the actual
speed. The output is disabled when the key is pressed again. This function is independent of the set minimum number of
stitches (parameter 184).
6.19.5 High Lift for Walking Foot Operational Mode Not Stored with Minimum Number
of Stitches (Pa. 138 = OFF, Pa. 184 = >0)
By pressing the key “high lift for walking foot“, the output “high lift for walking foot“ is enabled depending on the actual
speed until the key is released or the stitches set using parameter 184 have been executed.
When the key is pressed at machine standstill, the high lift for walking foot is enabled and remains On after the start of
sewing, at least for the set minimum number of stitches. Prolongation of the ON period is possible by keeping the key
pressed down until after stitch counting.
Note
If several speed limitations are activated at the same time, the maximum speed is limited to the lower value.
When using the V820 control panel, direct access is possible by means of the function key (key 9)!

The speed is limited to 2000 RPM or 3000 RPM using the control inputs on A/9 (DB2000) and A/10 (DB3000). The speed
limitations can be varied using parameters 117 and 289. When changing the switching state of the control inputs, the
respective speed limitation is delayed by approx. 50 ms or is released.
Note
If several speed limitations are activated at the same time, the maximum speed is limited to the lower value.
6.20.2 Analog Speed Limitation
The maximum speed can be limited by an analog voltage on input A/3. The analog voltage is generated by a potentiometer
which functions as voltage divider. If no potentiometer is connected, the maximum voltage is applied to the input. A
potentiometer for speed limitation on the control is also possible.
6.20.3 Analog Speed Limitation Speedomat
The speedomat function enables a speed limitation depending on the set sewing foot high lift (21 levels). The actual value
of the high lift is transmitted to the control by the position of a potentiometer (10kΩ) with an angle of rotation of 60°,
which is coupled with the high lift shaft. The maximum angle of rotation of the high lift shaft is 48°. Thus the setting range
of the potentiometer is from 9kΩ (nmax = 4.5V on socket A/3) to 1kΩ (nlim. = 0.5V on socket A/3).
Potentiometer connections see chapter "Connection Diagram".

Parameter 140/144 = 1: Needle up
When the key is pressed, the drive runs from position 1 to the reverse position. This does not depend on whether reverse
motor rotation is On or Off. If parameter 180 is set to 0, the drive stops in position 2. If the drive is outside the slot position
1, it does not move for safety reasons. The function is blocked after power On until sewing is started.
Parameter 140/144 = 2: Needle up/down
When the key is pressed, the drive runs from position 1 to the reverse position or from the reverse position to position 1.
This does not depend on whether reverse motor rotation is On or Off. If parameter 180 is set to 0, the drive stops in position
2. If the drive is outside the slot between position 1 and 1A or position 2 and 2A, it runs to the next possible position. After
power On, the drive runs to the next position identified.
Parameter 140/144 = 3: Single stitch
When the key is pressed, the drive performs one rotation from position 1 to position 1. If the drive is in the reverse position,
it runs to position 1 when pressing the key and from position 1 to position 1 each time the key is pressed again.
Parameter 140/144 = 4: Single stitch with normal stitch length
When the key is pressed, the drive performs one rotation from position 1 to position 1. If the drive is in the reverse position,
it runs to position 1 when pressing the key and from position 1 to position 1 each time the key is pressed again. At the same
time, the output “switch stitch length” on socket A/30 is enabled and the corresponding light emitting diode on socket A/29
disabled.
Parameter 140/144 = 5: Needle in position 2
When the key is pressed, the drive runs to position 2 or reverse position, independently of its present position. This function
is also possible after power On.
Parameter 140/144 = 6: Machine stop in position 2
After the key has been pressed, the drive stops in position 2 and the sewing foot is lifted. The machine run blockage symbol
blinks on the V820 and “stop” on the V810, respectively. The drive functions are blocked. Only after power Off/On is the
drive again ready for operation.
