Outputs:
FL = Sewing foot lifting FL1 = Sewing foot lifting without pulsing
VR = Backtacking STV = Stitch condensing
FA = Thread trimmer FA1 = Thread trimmer pos. 1...1A
FA2 = Thread trimmer pos. 1A...2 FA1+2 = Thread trimmer pos. 1...2
FA-V = Thread trimmer forward FA-R = Thread trimmer backward
FAU = Bobbin thread trimmer FAO = Needle thread trimmer
FSPL = Thread tension release AH = Tape cutter
FW = Thread wiper AH1/AH2 = Fast scissors
ML/NK = Machine running / Needle cooling KS = Chain suction
RB = Chain blowing in opposite direction STB = Blow fabric onto stack
KB = Chain blowing KS+KB = Chain suction + blowing
MST = Machine at standstill HP/FF1 = High lift for walking foot /
PD≥1 = Pedal steps 1...12 flip-flop 1
PD=0 = Pedal step 0 PD≤-1 = Pedal steps –1 / -2
L-STL = Indicator lamp for stitch length PD-2 = Pedal step -2
FZ = Thread puller DR-UK = Reversal of motor direction
IMP = Impulse STS = Stitch lock
LFA = Top cover thread cutter BR = Hot thread chain cutting
2 Putting into Service
Before putting the control into service, the following must be ensured, checked and/or adjusted:
" The correct installation of the drive, position transmitter and accompanying devices, if necessary
"
The correct selection of the trimming operation by means of parameter 290
" If necessary, the correct adjustment of the direction of motor rotation by means of parameter 161
" The correct selection of the functions of keys (inputs) by means of parameters 240...249
" The setting of the transmission ratio between motor shaft and machine shaft by means of parameter 272
" The setting of the type of position sensor by means of parameter 270
"
If necessary, the setting of the number of angular degrees after the sensor position by means of parameter 271
" If necessary, the setting of the positions by means of parameter 171
(possible with all settings of parameter 270)
" The correct positioning speed by means of parameter 110
"
The correct maximum speed compatible with the sewing machine by means of parameter 111
" The setting of the remaining relevant parameters
"
Start sewing in order to save the set values
