6.17.9 Sewing foot high lift (Function module A)
Function with or without control panel
Parameter
High lift for walking foot with output A
High lift walking speed
high lift for walking foot ratcheting = 1 / temporary = 0
Run-out time of the high lift walking speed after high lift for walking foot is turned off.
Minimum stitch count with high lift for walking foot
If high lift for walking foot is on, the transport roller remains raised/lowered

When key A is pressed, output A and LED A are turned on and thus brought to the maximum sewing foot lift.
Turning on the solenoid valve is possible at any time. The maximum speed is limited to the high lift walking
speed (DB2000). If the momentary speed is higher than the high lift walking speed, the drive brakes to the high
lift walking speed before output A is turned on.
When maximum high lift is disabled, output A and LED A are turned off immediately, but the speed limitation is
only removed after a configurable amount of time (parameter 152).
Three different modes can be selected with parameters:
High Lift for Walking Foot Operational Mode Stored (parameter 138 = 1).
The first time key A or a knee switch is pushed, output A is turned on, and it is turned off on the second time.
High Lift for Walking Foot Operational Mode Not Stored (parameter 138 = 0, parameter 254 = 0).
Output A is turned on as long as key A or a knee switch is pressed.
High lift for walking foot with minimum stitch count (parameter 138 = 0, parameter 254 > 0).
When key A or a knee switch is pressed, output A is turned on and remains turned on until the configured stitch
count (parameter 254) has been counted down.
 When key A is pressed when the drive is not running, high lift is turned on, and remains turned on after
sewing starts at least for the configured stitch count.
 Extension of the activation time is possible if the key remains pushed down past the end of the stitch
counting.
 When the key is pressed during counting, counting is always started over.
Parameter 262 can be used to set the following function if the parameter 250 is set to "11" and 255 to "5", or
parameter 250 is set to "5" and 255 to "11".
262 = 0 The transport roller remains lowered if high lift for walking foot is turned on.
262 = 1 The transport roller is lifted when high lift for walking foot is turned on.
When using the V820\V850 control panel, direct access by means of the function key (key 9) is possible!
