Setting of Efka positioning motor
The function of the positioning motor is determined by its program,
setting of the motor parameters and the machine stop positions.
If the sewing machine is supplied as disassembled, the motor setting
must be performed by the purchaser. If the sewing machine is supplied
as complete, the motor is already set by the sewing machine
manufacturer.
6.1 Setting of positioning motor parameters
Setting of the motor parameters is carried out in two steps. In the first
step, parameters for a group of classes of sewing machines are set by
means of the “autoselect” function. In the second step, some of the set
parameters change to adjust to the particular class.
6.1.1 Setting of parameters through “autoselect” function
The motor control system is equipped with the “autoselect" device
identifying which sewing machine was connected to the motor (with the
connecting cable). At the motor switch-on, the resistance value of the
resistor, for this purpose located inside the machine head, is
automatically measured. On this base, required parameter values are
automatically set up. If the control system is not capable of identifying
the valid resistance, the motor control will run only with so-called
safety operating functions to prevent the sewing machine damage.
6.1.2 Setting of Efka motor parameters
Attention!
Change of the parameter values must be performed responsibly and
with consideration. A wrongly set control may cause the machine
damage!
Warning!
Through the so-called master-reset (see section 6.3) all parameter
values can be set up back to the pre-set values.
