7.4 Unlocking the Chain (Mode 5/6/7)
Function
Parameters
Number of run-out stitches when unlocking the chain
Function “unlock the chain” in modes 5, 6 and 7
(c6)
(mEk)
184
190
Upon unlocking the chain at the seam end, the functions
thread trimming
and tape cutter/fast scissors are
automatically suppressed. When setting parameter
190 = 3
, the function
tape cutter/fast scissors
is however
possible. After pressing the key "unlocking the chain" and with pedal in position 0 (neutral), the drive always
stops in position 1.
Settings necessary for the operation “unlocking the chain”:
Set “unlock the chain” using parameter
190 =1 / 2 / 3 / 4
(
190 =0
“unlock the chain” off)
Set
switch-on delay
using parameter
181
and
reversing angle
using parameter
180
Determine the
function of the key “unlock the chain”
using one of the parameters
240...246
If parameter
290
is set at“
190 =0
Unchaining switched off
190 =1
Sequence with pedal in position -2 from machine run or from position 2:
- Press key "unlock the chain"
- Run at positioning speed to position 1
- Sequence of reversing angle at positioning speed after a switch-on delay that can be set
190 =1
Sequence with pedal in position -2 from standstill in position 1:
- Press key "unlock the chain"
- Run at positioning speed to position 1
- Sequence of reversing angle at positioning speed after a switch-on delay that can be set
190 =2
Automatic sequence with light barrier at the seam end without tape cutting / pedal in
position
–2 according to the setting of parameter 019
- Press key "unlock the chain"
- Run to position 1 after light barrier sensing
- Sequence of reversing angle at positioning speed after a switch-on delay that can be set
190 =3
Automatic sequence with light barrier on the seam end with tape cutter and run-out
stitches(Only possible in mode 7 and if parameter 018 =0 )
- Press key "unlock the chain"
- After light barrier detection, sequence of the compensation stitches and end count up to tape
cutting
- Run-out stitches up to unlocking the chain, adjustable with parameter 184
- Sequence of reversing angle at positioning speed after a switch-on delay that can be set
190 =4
Sequence with pedal in position
–2 / no unlocking of the chain if seam end with light
barrier, cutting and run-out stitches is set:
- Press the pedal to position -2
- Run at positioning speed to position 1
- Sequence of reversing angle at positioning speed after a switch-on delay that can be set
- No unlocking of the chain at the seam end with light barrier
-
Reverse motor rotation is suppressed when the drive stops. The signals “blow fabric onto stack”,
M2 and “sewing foot lift” will be issued.
