Operation Manual

6 Basic adjustment of the positioning drives

The function of the positioning motor is determined by its program,

setting of the motor parameters and stop positions of the sewing

machines. If the sewing machine is supplied in a disassembled

condition, the motor should be set by the purchaser. If the sewing

machine is supplied in an assembled condition, the motor has already

been set by the sewing machine manufacturer.

Attention!

The parameter value must be changed with consideration and

responsibility. A wrong setting of the control can cause the damage of

the sewing machine!

6.1 DAC basic/classic drive

The sub-class of this drive type has already been pre-set in the

purchased control unit on c ondition that the sub-class is known to the

manufacturer; i. e. a complete sewing machine and a drive have been

purchased. This can be changed either by a new software installation

by means of a D AC Dongle device and by a s ubsequent selection of

the sub-class, which is done when a separate control unit DAC has

been bought. Another possibility is the installation of the parameter

set by connecting a s o-called sewing machine identification (Masch.ID)

with the existing parameter set of the particular sub-class to the DAC

unit. This possibility can be made use of if the client has already owned

the same sewing machine with the DAC drive, and when the client

wants to copy the parameter set from that.

After the parameter set installation it is necessary to set the reference

position for the correct positioning (usually, the needle tip at the level

of the throat plate) at the parameter t0810, and then to adjust, if

needed, the maximum sewing speed at the parameter t0800.

Detailed information and a detailed description of the parameter

setting is included in the publication “Operating instructions DAC

basic/classic” enclosed by the drive manufacturer, “Parameter sheet

DAC basic/classic”, which is specific for the particular sub-class, or at

the website w w w.duerkopp-adler.com.

6.2 DAC eco drive

The same rules are applicable to the DAC eco drive for the sub-class

selection, and the software installation is the same as for the DAC

basic/classic drives. Only the hardware manufacture of the units is

different, and that is why the interface for the DAC Dongle device is

common with the control pedal interface, and the parameter setting is

realized by means of the pushbuttons on the control box front panel.

Detailed information with a detailed description of the parameter

setting is included in the publication “Operating instructions DAC eco”

enclosed by the drive manufacturer, or at the website
