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.
6.3 Efka drive The drive parameter setting is realized in two steps. As the first step, parameters are set for a group of sewing machine classes by means of the function “auto select“. This is done automatically according to the connected cable or switchboard where the so-called auto select resistor is contained. As the second step, the particular sub-class is selected at the parameter <290>, by means of which the parameters specific for this sub-class are automatically uploaded.
