Adapting Sc-380 To Dnu-1541-7 - JUKI DNU-1541 Engineer's Manual

(3) Adapting SC-380 to DNU-1541-7

When using SC-380 for DNU-1541-7, it is necessary to set the parameters below.
However, the manufacturing No. (Mfg. No.) of SC-380 is :
In case of "********* A" (in case there is "LU51" of the model LU-1510 is in the table of simplified setting value
for JUKI sewing machine of SC-380) and in case of "*********" (in case there is no "LU51" of the model LU-
1510 in the table of simplified setting value for JUKI sewing machine of SC-380), the contents to be set are
different. So, be careful.
1) In case the manufacturing No. (Mfg. No.) is "********* A" :
1. Select LU-1510 (LU51) from the table of simplified setting value for JUKI sewing machine. (Select
program mode [1] :
2. Change the parameters below.
For the selection of each program mode from the normal mode and the details of functions, refer to the
Engineer's Manual for the SC-380.
1 P mode (selection :
Function name
Thread trimming mode
Presser lifter output duty
2 C mode (selection :
Function name
Change-over of input
signal function
(Caution) 1. In case of the machine head with DL device, set as I2 = IO1.
(Caution) 2. In case of the machine head with 2-pitch device, set as IF = IO4, IFA = ON and OB = OT4.
3 D mode (selection :
Function name
No. of stitch compensation
for tacking
2) In case the manufacturing No. (Mfg. No.) is "*********" :
1. Select LU-22*0 (LU2S) from the table of simplified setting value for JUKI sewing machine. (Select
program mode [1] :
(Caution) Do not select LU2v. The alternate vertical movement amount device does not work
normally with LU2v.
2. Change the parameters below.
For the selection of each program mode from the normal mode and the details of functions, refer to the
Engineer's Manual for the SC-380.
