6.24.4 2nd Thread Tension Release (FSPL2)
Functions Parameter
Function of output B5/6 “motor running” (mmL) 198 = 1
Function of output B5/6 “thread tension release depending on speed” 198 = 2
Function of output B5/6 “thread tension release depending on speed” 198 = 3
Parameter 198 = 1 Motor running
Parameter 198 = 2 If the actual speed is higher than the speed set using parameter 120, FSPL2 is On.
If the actual speed is lower than the speed set using parameter 120, FSPL2 is Off.
Parameter 198 = 3 If the actual speed is lower than the speed set using parameter 120, FSPL2 is On.
If the actual speed is higher than the speed set using parameter 120, FSPL2 is Off.
Special feature if parameter 198 = 2 or 3 (function “2nd thread tension release”):
Parameter 198 = 2 Parameter 198 = 3
During start or end backtack FSPL2 = Off FSPL2 = On
Output “thread tension release On
(ST2/36)
FSPL2 = On FSPL2 = Off
Output sewing foot lifting On
(ST2/35)
FSPL2 = On FSPL2 = Off
6.24.5 Thread Tension Reduction
Functions Parameter
Thread tension reduction , function of the key on socket D/3 (Fc3) 147 = 1
Thread tension reduction , function of the key on socket D/6 (Fc6) 149 = 2
Thread tension can be reduced by pressing a key connected to D/3 or D/6, depending on the programming of parameters
147 and 149. Thread tension reduction is indicated by a light emitting diode.
6.24.6 Coupling Thread Tension Release with the Sewing Foot
Functions Parameter
Coupling thread tension release / reduction with sewing foot lifting (kFn) 196
Parameter 196 = 0 Thread tension release and thread tension reduction “Off” during sewing foot lifting.
Parameter 196 = 1 Thread tension release and thread tension reduction “On” during sewing foot lifting in the seam.
Parameter 196 = 2 Thread tension release and thread tension reduction “On” during sewing foot lifting after thread
trimming.
Parameter 196 = 3 Thread tension release and thread tension reduction “On” during sewing foot lifting in the seam
and after thread trimming.
If parameter 147 = 1 (key on socket D/3) or parameter 149 = 2 (key on socket D/6), thread tension reduction can be enabled
at any time. The operational mode of the keys is stored. Furthermore, the function can be assigned to key A or B on the
control panel using parameters 293 and 294.
6.24.7 Coupling Thread Tension Reduction with High Lift for Walking Foot / Speedomat
Functions Parameter
