7.8.1 High lift for walking foot signal output M16 (flip flop 1)
The high lift for walking foot function can only be executed if it has been activate (parameter 137 = 1).
The function is triggered by a key assigned to which input function 13 or 14 has been assigned.
If the high lift for walking foot function is deactivated (parameter 137 = 0) the "Machine idle" signal appears on
output M16.
7.8.2 High lift for walking foot operational mode not stored
The high lift for walking foot function is in operational mode Not Stored if input function 13 has been
programmed for the corresponding key.
Pressing the key turns on high lift for walking foot speed limitation. High lift for walking foot is turned on when
the speed falls below the limit.
When the key is released, high lift for walking foot is turned on.
The minimum number of stitches and run-out time influence the process.
7.8.3 High lift for walking foot operational mode stored (flip flop 1)
The high lift for walking foot function is a ratchet effect if input function 14 has been programmed for the
corresponding key.
On the first actuation of the key, the high lift for walking foot function is turned on with the same operation as
described in the section "High lift for walking foot operational mode not stored", and turned off on the second
actuation.
Any minimum number of stitches is not taken into consideration, but the run-out time is.
7.8.4 Minimum number of stitches for high lift for walking
The high lift for walking minimum number of stitches only applies if the function "High lift for walking foot
operational mode not stored" is programmed.
After high lift for walking foot is turned on, the magnet stays turned on until the number of stitches programmed
in parameter 185 is reached.
This is particularly useful, since if the key is pressed for a short time the high lift for walking foot remains in
effect for a minimum number of stitches,
7.8.5 High Lift Walking Speed Run-Out Time
If high lift for walking foot is turned off, the speed remains limited for the time configured with parameter 152.
7.8.6 Speed Limitation Depending on High Lift
Speed limitation depending on high lift depends on the setting of the handwheel on the machine arm. It may be
activated or deactivated using parameter 503.
Deactivated. The speed limitation n10 set with parameter 117 is in effect.
Activated. The speed limitation corresponds to a value dependent on the lift height configured.
