The thread tension release signal can be turned on with a delay relative to the thread trimmer. The delay is
entered as an angular value in parameter 192. Shut-off takes place in position 2. However, the signal can be
extended by the configurable time in parameter 191.
Should position 2 not be reached due to mechanical error, the output is turned off after 10 sec. This protects a
solenoid with a low permitted activation time from destruction.
6.21.1 Coupling of sewing foot, thread tension release, and thread tension reduction.
Function with or without control panel
Parameter
Coupling of sewing foot, thread tension release, and thread tension reduction.
(kFn)
196
Parameter 196 can be used to set the coupling of sewing foot, thread tension release, and thread tension reduction.
196 = 0
Coupling of the sewing foot to the thread tension release and thread tension reduction in the seam and after
thread trimming off.
196 = 1
Thread tension release and thread tension reduction in the seam during sewing foot lift on.
196 = 2
Thread tension release and thread tension reduction after thread trimming during sewing foot lift on.
196 = 3
Thread tension release and thread tension reduction in the seam and after thread trimming during sewing
foot lift on.
When parameter 250, 255 is set and/or 275 = 7, thread tension reduction can be turned on/off at any time. The key functions
are latching.
6.21.2 Coupling of thread tension reduction, high lift for walking foot, and Speedomat
Function with or without control panel
Parameter
Coupling of thread tension reduction, high lift for walking foot, and Speedomat
(kFh)
197
Parameter 197 can be used to set the coupling of thread tension reduction, high lift for walking foot , and
Speedomat.
197 = 0
Coupling of thread tension reduction with high lift for walking foot and with the Speedomat off.
197 = 1
The key on socket A/7 is used to turn off thread tension reduction and turn on high lift for walking
foot. The Speedomat has no effect.
197 = 2
When the high lift speed is reached by adjustment of the Speedomat, thread tension reduction is
turned off. The key on socket A/7 has no effect
197 = 3
When the high lift speed is reached by adjustment of the Speedomat, thread tension reduction is
turned off.
The key on socket A/7 has the same effect as for Setting 1.
When parameter 250, 255 is set and/or 275 = 7, thread tension reduction can be turned on/off at any time. The
key functions are latching.
6.22 Speed-dependent thread tension
Function with or without control panel
Parameter
Function of output M14 (ST2/26
Switching point for speed-dependent thread tension
(MML)
(nFS)
198
143
The "motor running" output (M14, socket A (ST2)/26) can be programmed for the function "Speed-dependent
thread tension". The switching point depends on the speed selected with parameter 143.
198= 1
Motor running
198= 2
Thread tension on if the speed is higher than that set with parameter 143.
Thread tension off if the speed is lower than that set with parameter 143.
198= 3
Thread tension on if the speed is lower than that set with parameter 143.
Thread tension off if the speed is higher than that set with parameter 143.
