EFKA AB221A/AB321A + AB222A/AB322A (BA)

The speed limitation can be switched on by pressing a key on any of the inputs in1...i10 and switched off by pressing the
key again. A signal output which can be programmed individually (inverted/non-inverted) is provided for the speed
limitation. Furthermore, the function of signal output M10 can be determined after “power on”.
Settings necessary for speed limitation n11
Assign the function "speed limitation n11" to the key using one of the parameters 240...249 = 22. This function has a flip-
flop effect.
Determine using parameter 186 whether signal M10 for speed limitation n11 shall be inverted or non inverted.
186 = 0 Speed limitation n11 On/Signal M10 On or Speed limitation n11 Off/Signal M10 Off.
186 = 1 Speed limitation n11 Off/Signal M10 On or Speed limitation n11 On/Signal M10 Off.
Determine using parameter 187 whether signal M10 is issued at socket ST2/29 after “power on”.
187 = 0 Signal M10 not active after "power on"; speed limitation n11 according to setting of parameter 186
(inverted/non-inverted)
187 = 1 Signal M10 active after "power on"; speed limitation n11 according to setting of parameter 186
(inverted/non-inverted)
9.19 Disabling of Flip-Flop Functions at the Seam End
Function with or without control panel Parameter
Disabling of flip-flop functions at the seam end On/Off (FFm) 183
Determine using parameter 183 whether signals M6 and/or M10 shall be switched off at the seam end. If 183 = 0, the
signals can be switched off only using the appropriate keys.
183 = 0 Signal M6 (flip-flop 1) and signal M10 (flip-flop 2) are not switched off at the seam end.
183 = 1 Signal M6 (flip-flop 1) is switched off at the seam end.
183 = 2 Signal M10 (flip-flop 2) is switched off at the seam end.
183 = 3 Signal M6 (flip-flop 1) and signal M10 (flip-flop 2) are switched off at the seam end.
9.20 Bobbin Thread Monitor
Function with or without control panel Parameter
Bobbin thread monitor On/Off (rFw) 030
Number of bobbin thread monitor stitches (cFw) 031
For bobbin thread monitor operation a number of stitches depending on the length of the bobbin thread has been preset
using parameter 031. After the execution of these stitches the drive stops and a visual signal appears on the display. If a
control panel is connected, an acoustic signal is also issued if parameter 127 is set accordingly. This signals that the bobbin
thread will run out. After pressing the pedal again, the seam can be continued and the thread can be trimmed. After
inserting a full bobbin and pressing the ENTER key, a new sewing operation can be started.
Enable bobbin thread monitor:
Select parameter 030 = 1...3.
• Input the desired maximum number of stitches in parameter 031 (input value x 100 = number of stitches,
e. g. 80 x 100 = 8000).
• For starting the counter set the A or B key at “19” using parameter 293 or 294.
When using a control panel, an acoustic signal can also be enabled using parameter 127.
Start the sewing operation.
Bobbin thread monitor in operation:
030 = 0: Bobbin thread monitor is off.
030 = 1: The drive stops after the stitch counter has run out. The message "A7" appears on the control, and the bobbin
thread monitor symbol blinks on the V810/V820 control panel, respectively. There will be an acoustic signal if a
V820 is connected and parameter 127 is set at “1“.
030 = 2: The drive stops after the stitch counter has run out. The message "A7" appears on the control, and the bobbin
thread monitor symbol blinks without stopping automatically on the V810/V820 control panel, respectively.
There will be an acoustic signal if a V820 is connected.
030 = 3: The drive stops after the stitch counter has run out. Thread trimming is possible with pedal in pos. –2. The start
is blocked. The message "A7" appears on the control, and the bobbin thread monitor symbol blinks on the
V810/V820 control panel, respectively. There will be an acoustic signal if a V820 is connected and parameter
127 is set at “1“.
