Upon pressing the external key “high lift for walking foot” depending on the setting of parameters 240...246, the
speed is limited to high lift walking speed. The solenoid for high lift for walking foot is switched on if the speed 
high lift walking speed. It is possible to program run-out stitches using parameter 185. This way, high lift for
walking foot remains on until stitch counting has been completed. The speed limitation remains effective during
run-out time after the solenoid for high lift for walking foot has been switched off.
7.14.4 High Lift for Walking Foot Operational Mode Not Stored (Parameters 240...246 = 13)
The following function is performed if "0" run-out stitches have been programmed using parameter 185:
 Press the key “high lift for walking foot”; signal “high lift for walking foot” is On.
 Release the key“ high lift for walking foot”; signal “high lift for walking foot” turns off.
The following function is performed if ">0" run-out stitches have been programmed using parameter
185:
 When pushing the “high lift foot for walking” key for the first time at a drive stand still: The “high lift foot for
walking” switches on and remains on after the button is released.
 When pressing the “high lift foot for walking” key again at drive standstill: The “high lift foot for walking”
signal switches off again.
If the signal “high lift for walking foot” is On when starting the drive, the speed will be limited. The signal turns off
after the run-out stitches have been executed, and the speed limitation will be disabled after the run-out time
(Parameter 152). If the key is held down until after counting, high lift for walking foot remains On. If the key is
pressed only briefly, counting takes priority.
While the drive is running, if ">0" run-out stitches have been programmed using parameter 185:
 Pushing the “high lift foot for walking” key while the drive is running: The “high lift foot for walking” signal and
“high lift foot for walking” speed switch on.
 Release the “high lift foot for walking foot” key while the drive is running: The signal “high lift foot for walking
foot” switches off and depending on the run-out time (Parameter 152) the speed limit is disabled again.
7.14.5 High Lift for Walking Foot Operational Mode Stored /Flip-Flop 1 (Parameters
240...246 = 14)
 Upon first actuation of the “high lift foot for walking” key while the drive is running: The “high lift foot for
walking” signal and “high lift foot for walking” speed switch on.
 By repeatedly pushing the “high lift foot for walking” key while the drive is running: Signal “high lift foot for
walking” switches off immediately and after the run-out time (Parameter 152), speed limiting is released.

The lift-dependent speed limitation depends on the position of the adjustment wheel for the lift, which is coupled
with a potentiometer It may be activated or deactivated using parameter 126.
126 =0
Deactivated. The maximum speed n10 set with parameter 117 is in effect.
