There are various setting possibilities with the following parameters in the overlock mode (mode 7).
018 =0
Sequence with stop.
018 =1
Sequence without automatic stop at the seam end. When the command “run” is given, the drive
runs at the pre-selected speed. The program switches to the next start of a seam without issuing
signals M1/M2, when the pedal is in pos. 0 (neutral) or the light barrier is covered.
018 =2
Sequence as with setting 1. But with pedal in pos. 0 signals M1/M2 will be issued, and the
program switches to the next start of a seam.
018 =3
Sequence as with setting 1. But with pedal -2 signals M1/M2 will be issued, and the program
switches to the next start of a seam. Intermediate stop and sewing foot lifting with pedal in pedal -
1 is possible.
018 =4
If the light barrier is covered during the end count for chain suction, the program switches
immediately to the next start of a seam. If the end count has been completed and the light barrier
remains uncovered, the drive stops immediately.
018 =5
Tape cutting at the start of the seam with stop.
022 =0
The chain suction signal at the seam end is disabled after count c2.
022 =1
The chain suction signal at the seam end remains on until pedal in pos. 0 (neutral).
022 =2
Chain suction until the drive is at standstill and the switch-off delay (Parameter 237) has elapsed.
The switch-off delay will be disabled whenever a new seam is started.
025 =0
Start counting for thread tension release at the start of the seam.
025 =1
Start counting for thread tension release when the light barrier is covered.
193 =0
Thread tension release and chain suction after the light barrier compensating stitches.
193 =1
Chain suction from light barrier uncovered onwards and thread tension release after the light
barrier compensating stitches.
199 =0
Thread tension release On at the seam end until pedal in pos. 0 (neutral).
199 =1
Thread tension release On at the seam end or at the start of the seam.
199 =2
Thread tension release On at the seam end or at the start of the seam and after “power On“.
267 =0
Start count cancellation by light barrier uncovered impossible.
267 =1
Start count cancellation by light barrier uncovered.
Chain suction or tape cutting at the start of the seam are cancelled whenever the light barrier
senses “uncovered”, and the seam end will be initiated.
It is possible to select the speed function for stitch counting at the start of the seam and at the seam
end using the following parameters.
143 =0
Speed controllable by the pedal up to the set maximum speed (Parameter 111).
143 =1
Fixed speed (Parameter 112) without an affect by the pedal. Stop with pedal in pos. 0.
143 =2
Limited speed (Parameter 112) controllable by the pedal up to the set limit.
143 =3
At fixed speed (Parameter 112), can be cancelled or interrupted depending on the setting of parameter
019.
144 =0
Speed controllable by the pedal up to the set maximum speed (Parameter 111).
144 =1
Fixed speed (Parameter 113) without an affect by the pedal. Stop with pedal in pos. 0.
144 =2
Limited speed (Parameter 113) controllable by the pedal up to the set limit.
144 =3
At fixed speed (Parameter 113), can be cancelled or interrupted depending on the setting of parameter
019.
