The Teaching Operation; Pre-Heating Control - Mitsubishi PLK-E1008H Technical Manual

6-2. The teaching operation

Detail descriptions for pattern input are mentioned in TECHNICAL MANUAL <Operation Panel
Section>. As for the input method of PLK-B1008H, it is necessary to operate the peculiarity
compared with other PLK machines. Peculiar point is
STOP code [USTP] just after TRIM code is required for thermal trimming sequence.
There are two ways to put codes in the pattern data (Using Code Data Input method in the
Input Mode or Modifying code data method in the Modification mode).
Please refer to the [Code data input] or [Modifying code data] in the technical manual
[Operation Panel] for detail operation method.
If STOP code is not put just after TRIM code, the X-Y table and needle will move during
thermal trimming procedure and cause to damage the machine.

6-3. Pre-heating control

To secure the trimming, it is available to use pre-heating by input Function Code No.4 (FN4) in
the pattern data. Relationship between FN4 and pre-heating behavior is described as below.

When FN4 code is input once, pre-heater is continue to on until trim code is appeared.(ex.1)
When FN4 code is input twice, pre-heater is on at first code and off at second code.
Usually FN4 is better to put only 1 time.
If the residual heat time is short, sufficient heating to trim the thread may not be attained.
When sewing a pattern with few stitches, the heating time must be increased by slowing
the stitching speed, etc.
