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)!
