EFKA AB221A/AB321A + AB222A/AB322A (BA)

New start after machine run blockage

Function with or without control panel Parameter

New start after machine run blockage (Pdo) 234

Parameter 234 determines how a new start is possible after closing and/or opening the switch.

234 = 0 New start after disabling machine run blockage without influence by the pedal. This setting is applicable, for

example, to automats.

234 = 1 New start after disabling machine run blockage only if the pedal is in position 0 (neutral).

9.15 High Lift for Walking Foot Signal Output M6 / Flip-Flop 1

Function with or without control panel Parameter

High lift for walking foot On/Off (hP) 137

Signal “high lift for walking foot M6” when key is closed/open (ihP) 263

High lift for walking foot is effective only if input function 13 or 14 has been selected using parameters 240...249 and

parameter 137 = 1. With all other settings high lift for walking foot is ineffective. The signal “machine at standstill” is

issued at the corresponding output (M6). Select using parameter 263 whether the key is to be active when open or when

closed.

263 = 0 Signal “high lift for walking foot M6” is issued when key is closed

263 = 1 Signal “high lift for walking foot M6” is issued when key is open

9.15.1 High Lift Walking Speed

Function with or without control panel Parameter

High lift walking speed (n10) 117

9.15.2 High Lift Walking Speed Run-Out Time

Function with or without control panel Parameter

High lift walking speed run-out time (thP) 152

9.15.3 High Lift Walking Stitches

Function with or without control panel Parameter

Number of high lift walking stitches (chP) 185

Upon pressing the external key “high lift for walking foot” depending on the setting of parameters 240...249, 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.

9.15.4 High Lift for Walking Foot Operational Mode Not Stored

(Parameters 240...249 = 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.
