6. Setting of 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 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 reset (see section 6.3) all parameter values can
be set up back to the pre-set values.
