Memory; File (Save) And Calling Keys; Disengagement Of Main Shaft - ELNA E9020 Service Manual

Memory

1) When a pattern or a letter is selected, it is automatically stored in memory.
2) The maximum number that can be stored in memory is 120. For the embroidery patterns, the number of patterns to be sewn changes in accordance with the size of
the frame or the size of the patterns stored in memory, and the limit ofthe number of patterns stored in memory is automatically computed and set.
3) The one-point pattern stitching pattern cannot be stored in memory or retained as the continuous pattern mode or the pattern mode.
Pattern selection + continuous key + pattern selection
Pattern selection + continuous key + retaining key
* For the retaining key, refer to the next page.
4) The vertical writing mode can be used for kana letters, Chinese characters and numerals. The embroidery patterns are effective for all patterns stored in memory.

File (save) and calling keys

1) The saving function saves a series of patterns stored in memory after the power to the machine is turned OFF. Once the power is re-turned ON, the saved patterns
can be called for sewing.
Turn ON the pattern case key to select
and the combined patterns for the embroidering are stored in the file of the specified No. in non-volatile memory (flash memory), and the data are saved even after
the power to the machine is turned OFF.
The condition of patterns which has been simultaneously stored in memory with the patterns such as inversion, increase, decrease, two colors, small letter, vertical
writing, vertical setting, rotation, letter interval, layout condition, etc. and the kind of embroidery frame are saved.
The file that has been saved once cannot save other patterns until the patterns saved in the file are erased.
2) If the embroidery frame installed on the machine, when calling the pattern with the calling key, is smaller than the one when it has been saved in the memory, editing
can be performed by the edit screen. Sewing cannot be performed, however, unless re-editing is peformed so that the pattern can enter inside the frame. In this case,
the error message will appear on the display.
3) Saving and calling under the embroidering mode is effective regardless of the patterns, kind of the embroidery card, built-in patterns or card patterns.

Disengagement of main shaft

1) Disengagement of the main shaft is performed by actuating the main shaft disengaging link by means of the needle throwing STM to disengage the rotation power
to the main shaft.
2) When the data of disengagement of main shaft occurs (70˚), the needle throwing STM starts driving from 287˚ and completes the motion by 0˚.
3) By the step 2) motion, the main shaft disengaging link moves to the disengaging position. (The STM completes the motion by 0˚.)
4) When the main shaft turns in the normal direction in the state that the main shaft disengaging link is in the disengaging position, the main shaft disengaging cam
slides by the main shaft disengaging link. The main shaft hand wheel and the main shaft are disengaged from each other, and the rotation power is cut.
: In this case, error message is given.
and turn ON the save key. Then the patterns that have been stored in memory for the patterns other than embroidering
