10.6.4 Function of the additional thread tension depending on the stroke
adjustment (HP) and the Speedomat
Parameter Stroke adjustment (HP) max.
adjustment via knee switch
F-197 = 0
F-197 = 1
F-197 = 2
F-197 = 3
(*) When the max. stroke adjustment (HP) is switched on via knee switch and the
HP-speed of parameter F-117 is reached by the "Speedomat", the additional thread
