＊ Do not change the set values with asterisk (*) mark as they are functions for maintenance. If the standard set value set at
the time of delivery is changed, it is in danger of causing the machine to be broken or the performance to be deteriorated. If
it is necessary to change the set value, please purchase the Engineer's Manual and follow the instructions.
Description
Stitch alignment can be carried out by changing the timing
of actuating the reverse feed stitching solenoid at the time of
overlapped stitching. When the set value for this parameter is
increased, the length of stitch at the end of A (C) process is
increased and the length of stitch at the beginning of B process
is decreased.
Stitch alignment can be carried out by changing the timing
of releasing the reverse-feed stitching solenoid at the time of
overlapped stitching. When the set value for this parameter
is increased, the length of stitch at the end of B process is
increased and the length of stitch at the beginning of C process
is decreased.
The first current value (ON duty) for the thread clamp is set with
this function setting item.
* Refer to the "explanation of the thread clamp solenoid oper-
ation" in the Engineer's Manual for details.
This parameter is used to display the current value of the
thread trimming counter.
This function rotates the main shaft in the reverse direction of
sewing to bring the needle bar to the highest position.
ON: Reverse-revolution operation is in the ON state
OFF: Reverse-revolution operation is in the OFF state
The minimum sewing speed of the sewing machine by operat-
ing the pedal is set with this function setting item.
Sewing speed to be used when performing thread trimming is
set with this function setting item.
The operation of the presser foot when the back part of pedal is
depressed is set with this function setting item.
0: Presser foot does not operate even when the back part of
pedal is depressed.
1: When the back part of pedal is depressed, the presser foot
goes up to its upper position.
This parameter is used to set the time at which the work clamp
lifting solenoid is turned ON.
The maximum sewing speed is set with this function setting
item.(The MAX value differs with the type of machine head.
S: 5000; H: 4500)
Machine head type is selected with this function setting item.
2: DDL-7000AS-7
3: DDL-7000AH-7
* When you select the corresponding machine head and
press the enter switch, all existing data are initialized to the
initial values for the machine head you have selected.
The BT solenoid ON timing at the end of sewing is set with this
function setting item.
* This parameter applies only to the free stitching.
ON-angle of the thread clamp is set with this function setting
item.
OFF-angle of the thread clamp is set with this function setting
item.
The largest value that the bobbin counter can count is set with
this function setting item. When the counter reaches that value,
it stops counting.
The correction stitching function when turning the pulley by
hand upon completion of the constant-dimension stitching is set
with this function setting item.
0: Correction sewing function is enabled
1: Correction sewing function is disabled
* This parameter is enabled in the case "P11 Selection of
operation of BTSW" is set to "1: Needle up/down correction
switch".
The thread trimming operation after turning the pulley by hand
to move the sewing machine from the upper and lower posi-
tions is set with this function setting item.
0: Thread trimming operation is not carried out after turning
the pulley by hand.
1: Thread trimming operation is carried out after turning the
pulley by hand
The operation of the needle up/down switch after thread trim-
ming is set with this function setting item.
0: Needle up/down operation is carried out
1: One-stitch operation is carried out
Operation of the presser foot when the power is turned ON is
selected with this function setting item.
0: The presser foot does not operate (It operates when the
back part of the pedal is depressed.)
1: The presser foot goes up after automatically retrieving the
origin
2: The presser foot comes down after automatically retrieving
the origin
