Settings necessary for speed limitation n11
Assign the function "speed limitation n11" to the key using one of the parameters
240...249 =22
. This function
has a flip-flop effect.
Determine using
parameter
186
whether signal M10 for speed limitation n11 shall be inverted or non inverted.
186 = 0
Speed limitation n11 On/Signal M10 On or Speed limitation n11 Off/Signal M10 Off.
186 = 1
Speed limitation n11 Off/Signal M10 On or Speed limitation n11 On/Signal M10 Off.
Determine using
parameter
187
whether signal M10 is issued at socket ST2/29 after "power on".
187 = 0
Signal M10 not active after "power on"; speed limitation n11 according to setting of parameter
186
(inverted/non-inverted)
187 = 1
Signal M10 active after "power on"; speed limitation n11 according to setting of parameter
186
(inverted/non-inverted)
7.11 Disabling of flip-flop functions at the seam end
Function
with
or
without
control panel
Parameter
Disabling of flip-flop functions at the seam end On/Off
(FFm)
183
Determine using
parameter
183
whether signals M6 and/or M10 shall be switched off at the seam end.
If
183 = 0
, the signals can be switched off only using the appropriate keys.
183 = 0
Signal M6 (flip-flop 1) and signal M10 (flip-flop 2) are not switched off at the seam end.
183 = 1
Signal M6 (flip-flop 1) disabled at the seam end.
183 = 2
Signal M10 (flip-flop 2) disabled at the seam end.
183 = 3
Signal M6 (flip-flop 1) and signal M10 (flip-flop 2) are switched off at the seam end.
7.12 Bobbin thread monitor
7.12.1 Bobbin thread monitoring with sensors
Function
with
or
without
control panel
Parameter
Mode of bobbin thread monitoring via sensor
Number of stitches for the bobbin thread stitch count
(PFw)
(cPF)
835
836
Bobbin thread monitoring can be programmed for 1 or 2 sensors., The mode is selected using parameter
835
.
Connecting the sensors:
Sensor 1 to ST2/13 (In9), parameter 248 = 57.
Sensor 2 to ST2/5 (In5), parameter 248 = 56.
If one of the sensors detects that the bobbin thread amount has been reached, the bobbin thread monitoring
process is initiated. The LED in the multifunction key on the machine head starts to flash and thread stitch
counting is started.
When the stitch counting end is reached, the LED lights with a steady light. The further process is determined
by the setting selected by parameter
835
.
835 = 1
The drive stops. After the pedal is released and pressed again, the seam can be run to the end.
835 = 2
The drive does not stop, and the seam can run to the end.
835 = 3
Like mode 1, but for two bobbin thread monitoring sensors.
835 = 4
Like mode 2, but for two bobbin thread monitoring sensors.
In either case, after the thread is trimmed, restart is blocked until the bobbin replacement is confirmed by
pressing the 8 key on the control panel. The LED is turned off and the reset sequence for the sensor emitted.
Acknowledgement is also possible using the F1/F2 key if the parameter
293/294
has been programmed to 19.
If parameter 835 > 0 when power is turned on, or if it is changed later (to a value other than 0), a reset
sequence for the sensor is output on M7 (ST2/21).
