Function Of The Additional Thread Tension Depending On The Stroke Adjustment (Hp) And The Speedomat - DURKOPP ADLER 767 Instructions Manual

2.3 Function of the additional thread tension depending on the
stroke adjustment (HP) and the Speedomat
Parameter Stroke adjustment (HP) max. Stroke adjustment
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 tension is switched on
automatically.
1 = Additional thread tension is engaged
(= mechanically closed)
0 = Additional thread tension is not engaged
(= mechanically opened)
–
If the additional thread tension is closed, it remains closed during
the stroke adjustment.
–
When the machine is switched off, the previously set status of the
additional thread tension is maintained via the net.
