EFKA AB221A/AB321A + AB222A/AB322A (BA)

9.26.2 Start and End Counts

Function with or without control panel Parameter

End count (c2) at limited speed n4 until stop (c2) 000

Start count (c1) at limited speed n3 for chain suction (c1) 001

Count (c3) tape cutter at the start of the seam (c3) 002

End count (c4) for tape cutter at the seam end (c4) 003

Seam end in mode 7 through end count (c2) or (c4) (mhE) 191

Stitch counting speed at the start of the seam (n3) 112

Stitch counting speed at the seam end (n4) 113

The following settings are possible for determining the seam end using parameter 191:

191 = 0 Seam end after count c4 (tape cutter)

191 = 1 Seam end after count c2 (chain suction)

9.27 Function of Output Signal M8

Function with or without control panel Parameter

Functions of signal M8 (m08) 296

The following settings are possible using parameter 296:

296 = 0 Function signal M8 Off

296 = 1 Signal M8 “hemmer foot” is On at the start of the seam with pedal in pos. <0 and in the seam with signal

“machine running”.

296 = 2 Signal M8 “hemmer foot” is On at the start of the seam with pedal in pos. <0 and always in the seam.

296 = 3 Signal M8 enabled as “center cutter“.

296 = 4 Signal M8 is On with “needle up / down“.

296 = 5 Signal M8 alternates with M3 when set as “fast scissors“ on overlock machines (parameter 290 = 16 and

parameter 232 = 1).

9.28 Function of Output Signal M11

Function with or without control panel Parameter

Functions of signal M11 (m11) 297

The following settings are possible using parameter 297:

297 = 0 Function according to setting of parameter 290

297 = 1 Signal M11 is On whenever the light barrier is uncovered.

297 = 2 Signal M11 is On whenever the light barrier is covered.

297 = 3 Signal M11 is On only after light barrier uncovered or covered until seam end.

297 = 4 Signal M11 is On as with setting 3. Signal M5 (machine running), however, is Off while signal M11 is On.

297 = 5 Signal M11 is On from light barrier sensing, pedal in pos. –2 or hemmer foot signal off key onwards.

297 = 6 Signal M11 is On when the key on input in2 is open. Signal M11 is switched off after the section set using

parameter 007 has been executed, when the key on input in2 is closed. At drive standstill, signal M11 is switched

off immediately.

297 = 7 Signal M11 is issued whenever the operating hours counter reading (parameter 177) has reached the value of

service monitoring (parameter 217).

297 = 8 Signal M11 is issued whenever machine run blockage is enabled.
