6.1.3 Values of parameters specific for LP 2971, LP 2974
Parameter change for machines with gear rate of 28/28 teeth
Parameter Original value New value Parameter description
290* 0 3 Class of the machine
111 - - Max. sewing speed
170 - - Reference position (see chapter 6.2.2)
Parameter change for machines with gear rate 18/28 teeth
Parameter Original value New value Parameter description
290* 0 4 Class of the machine
111 - - Max. sewing speed
170 - - Reference position (see chapter 6.2.2)
* The parameter must be entered first.
Attention : to set up parameters higher as 200, it is necessary to enter
the control with a programmer’s level (via code 3112).
6.2 Setting of machine positioning
6.2.1 Position definition
Position 1
The needle is down at the stopping in the seam. The angle 225° is on
the hand wheel scale.
Position 2
The needle is up after trimming. The angle 35° is on the hand wheel
scale.
6.2.2 Setting the machine positioning for DC1550/DA321G drive
For the needle and other elements positioning the incremental sensor
located on the hand wheel is applied which gives 512 impulses
(increments) /value in ° is displayed on the display/ and one additional
impulse per rotation. In general, the particular position is defined by
the angle between this position and the reference position. The angle
is set by the corresponding parameter value (it is not, however,
identical with the parameter value). The position parameter values
have already been set – see chapter 6.1.3. The reference position still
remains to be set.
The reference position is defined by the angle 105° on the hand wheel
scale.
After dismantling, mounting, or replacement of the motor drive the
reference position must be set again.
A reference position setting is described in the operating manual of the
motor manufacturer Efka.
