6 Adjustment of Efka positioning motor (drive)
The function of the positioning motor (drive) is defined by its program,
drive parameter setting, and the machine stopping positions. If the
machine is supplied in the disassembled condition, the drive setting
must be carried out by the purchaser. If the sewing machine is supplied
in assembled condition, the drive is already set by the sewing machine
manufacturer.
6.1 Setting of positioning motor (drive) parameters
The setting of the drive parameters is carried out in two steps. In the
first step, the parameters for the family of sewing machine class
groups are set by the function “autoselect“. In the second step, some
of the set parameters are changed to be adjusted to the particular
class.
6.1.1 Setting of parameters by the “autoselect” function
The drive control system is equipped with the “autoselect“ device,
which is able to identify what sort of the sewing machine was
connected to the drive (with a connection cable). At the drive switching
on, the value of the resistance of the resistor located inside the sewing
machine head for this purpose is measured automatically. As a result
of this, the required parameter values are set automatically. If the
control system is not able to identify the valid resistance, the drive
control will run with so-called safety operation functions only to avoid
the sewing machine damage.
6.1.2 Setting of Efka drive parameters specific for LP 2971, LP 2974
Caution!
Change of the parameter value must be performed with consideration
and in a responsible way. A false setting of the control may cause the
machine damage!
Warning!
By the so-called master-reset (see chapter 6.3) it is possible to reset
all parameter values back to the preset values again.
For a detailed description of the various parameters of the control unit,
please consult the enclosed current issue of the instructions of the
motor manufacturer (see also
www.efka.net ).
