„Press the P key to turn off the display of the programmer, and turn the power off and on again.
Since initial setting is done when the power is turned ON, turn the power off and on after writing
extended option output. In this case, the output No. 15 is initial-set to work as an extended option
not as the left work clamp.
…Read short sewing data that consists of around 10 stitches, set the DIP SW A No. 1 (the presser
foot does not rise at sewing finish) to ON, and carry out sewing.
If the left work clamp rises for 1 second and descends every time the feed returns to the sewing start
position, it proves that No. 15 has worked as programmed.
2-2 Modifying programmed data
Modify the data created in the previous procedure 2-1
One FD can store only one option program. (FD file name is “bas900. seq”)
•After checking that the FD written in 2-1 is in the operation panel, display the extended option output
home screen shown in the following.
‚Read the written data with FD read icon.
ƒDisplay the output setting screen, set the timer 1 to 0.5sec (500mS) and the timer 2 to 0.5sec
(500mS). Input as follows:
For the timer 2, move the cursor to “1000”, which has already been set, write “0500” over it.
„After overwriting the option program to the FD following the same step of ƒ and„ of 2-1, press the
P key to turn off the display of the programmer, and turn the power off and on again.
…Read the sewing data and carry out sewing. Check that the left work clamp does not rise soon after
the feed returns to the sewing start position (because the timer 1 was set from 0 to 0.5 sec.) and the
time of the work clamp rise has become short (because the timer 2 was set from 1 to 0.5 sec).
2-3 Programming ON and OFF separately
2-1 and 2-2 are examples that No. 15 automatically returns to OFF after it is ON during the set
time of the timer 2.
The following procedure is to create the program which enables the left work clamp automatically
to open at sewing start (option output No. 15: ON) and close at the same time of sewing start
