Efka dc1550 - Stitch Counting with Light Barrier; Free Seam and Seam with Light Barrier

Instruction Manual
- 38 -
Speed control for stitch counting can be selected using parameter 141.
141 = 0
Execution at pedal controlled speed
141 = 1
Execution at fixed speed n12, when pressing the pedal forward (position >1)
141 = 2
Execution at limited speed n12, when pressing the pedal forward (position >1)
141 = 3
Automatic execution at fixed speed after having pressed the pedal once. The procedure can be
interrupted by "heelback (-2)".
141 = 4
Automatic execution at fixed speed n1 after having pressed the pedal once. The procedure can
be interrupted by "heelback (-2)".
266 = 0
Speed n12 is activated when key is closed.
266 = 1
Speed n12 is activated when key is open.
The sewing speed is reduced in each stitch depending on the actual speed (max. 11 stitches before the end of
stitch counting), in order to be able to stop exactly at the end of counting. When the light barrier is on, free
sewing will be performed after stitch counting.

Speed control for the free seam and the seam with stitch counting can be selected using the speed mode.
142 = 0
Execution at pedal controlled speed
142 = 1
Execution at fixed speed n12, when pressing the pedal forward (position >1)
142 = 2
Execution at limited speed n12, when pressing the pedal forward (position >1)
142 = 3
Only for the seam with light barrier:
- Automatic execution at fixed speed after having pressed the pedal once.
- The seam end is initiated by light barrier.
- The procedure can be interrupted by heelback (-2).
- If the light barrier is not on, speed as with parameter setting 142 = 0.
When using a control panel, the maximum speed is displayed after power on and thread trimming and can be
varied directly using the +/- keys on the control panel. The setting range lies between the values of parameters
111 and 121.
