18.2 Setting the “Speedomat” function
For the “Speedomat” function the following values must be set.
–
The maximum speed of the machine at minimum stroke height is
set with the parameter F-111 (n2 - see parameter sheet).
–
The speed at maximum stroke height is set with the parameter
F-117 eingestellt (n10 - see parameter sheet).
–
The upper “speed breaking point” is the Speedomat step up to
which the maximum speed F-111 is effective. The speed limitation
begins with the next step. The adjustment is effected with the
parameter F-188.
–
The low er “ speed breaking point” is the Speedomat step from
which the speed is limited to F-117 (n10). The adjustment is
effected with the parameter F-188.

Minimum sewing foot stroke = no speed limitation = maximum speed n2
Maximum sewing foot stroke = maximum speed limitation = speed n10
The difference between maximum speed and speed at maximum stroke
adjustment is automatically and regularly distributed to the remaining
steps between the upper and the lower speed breaking point by the
control.
18.2.1 Setting the “Speedomat” f unction by means of control panel V810
The programming of the automatic speed adaptation is done by the
competent technicians.
The adjustment of the upper and the lower speed breaking point is
effected with the parameter F-188.
Base for the settings are :
F-111 = 3500; F-117 = 2000; breaking point preset-value 10 + 19
–
Set maximum speed with parameter 111 (3500 min
-1
).
–
Set stroke adjustment speed with parameter 117 (2000 min
-1
).
–
Input of parameter F-188.
–
Press key “E”.
The current Speedomat step (e.g. 9) and the matching speed
limitation (e.g. 3500) are indicated.
–
Press key “>>”.
The current values for the upper speed breaking point (e.g. 10) and
the lower speed breaking point (e.g. 19) are indicated.
–
Press key “>>”.
The current Speedomat step (e.g. 9) and the matching speed
limitation (e.g. 3500) are indicated.
–
Set new value for the upper speed breaking point (e.g. 12) by
means of the potentiometer, e.g. by turning the setting wheel.
–
Press key “>>”.
The current values for the upper speed breaking point (e.g. 10) and
the lower speed breaking point (e.g. 19) are indicated.
–
Press key “E”.
The new value (e.g. 12) for the upper speed breaking point is taken
over.
