8. ELECTRIC MECHANISM
<Memory switches 00 - 0F>
Switch
At the end of sewing, the feed plate will be returned to the sewing start point via
memo-00
mechanical home position.
Work clamp (button clamp) will move to the sewing start point, and then will be
lifted.
memo-01
(For models with solenoid specifications other than the KE-434*, the work
clamp rises at the final stitch to enable quick taking out of the workpieces.)
Feed will move automatically to the next starting point at the same time as a
memo-02 user program is switched.
(Normally it moves to the starting point after sewing starts.)
When sewing using programs, the programs which have been set will be sewn
memo-03
in numerical order. (Cycle sewing mode is set.)
The sewing speed will be fixed at the minimum speed for the maximum pitch of
memo-04 the sewing data. (Set this to ON if you are concerned that variations in pitch
may cause changes in the sewing speed.)
Increases the presser solenoid lifting force
memo-05
(Set to ON when using the optional spring for extra-heavy material)
memo-06 Enlargement and reduction ratio settings for X and Y become the same.
memo-07 The inner clamping device can be used with pneumatic specifications.
memo-08 Test feeding is carried out stitch by stitch when the foot switch is depressed.
The sewing start point becomes the reference point for enlargements and
memo-09 reductions. (The reference point for enlargements and reductions is normally
the center of the sewing frame.)
memo-0A Work clamp does not close. (KE-432*)
memo-0b Work clamp closes when the machine starts. (KE-432*)
Needle stops in up position during emergency stop.
memo-0c (EMERGENCY STOP switch is available as an option except for KE-434*, 435*,
484C)
The bar tacking stitches (with a pitch of less than 1 mm) are also enlarged and
memo-0d reduced. (Normally stitches with a pitch of less than 1 mm are not enlarged or
reduced.)
Test feeding will be performed at the same speed as that for actual sewing.
memo-0E
(This is used for checking feeding operation.)
After sewing is finished, the work clamp automatically opens and closes once
memo-0F
(practice operation).
*1 ON for KE-434B, 434C, and "--" at other times
*2 ON for solenoid/heavy material specifications of KE-434B, 434C, and "--" at other times
*3 ON when the inner clamping device is being used, and "--" at other times
*4 ON for BE-438B, 438C, and "--" at other times
<Memory switches 10 - 1F>
Switch
The optional emergency stop switch can be used. (KE-430*, 431*, 432*, 433B,
memo-10
BE-438*)
On when a two-stage tensioner is used. (Special order device that outputs from
option output No. 1)
memo-11
(Normally the tension opens when output is OFF, and the tension closes when
option output No. 1 is ON)
Pneumatic wiper can be used. (Special order device except for KE-484C that
memo-12
outputs from option output No. 2)
The inner clamping device moves forward at the 1/4-way mark and returns at
the 3/4-way mark for the pattern being sewn.
memo-13
(The device does not retract at this time, regardless of the setting for
memo-15.)
Solenoid wiper can be used (available as an option except for KE-434*
memo-14
pneumatic specification and KE-435*).
*5 ON for KE-484C, and "--" at other times
