<strong>STEP</strong>-<strong>FOUR</strong> motor control unit <strong>SF</strong>-<strong>C2</strong><br />
Item number: 9085000530<br />
This unit constitutes the link between the control signals coming from the computer and the<br />
stepper motors for the axle movement of the mechanics. Basically, this unit includes a<br />
corresponding mains power supply and four power modules which convert the pulse and<br />
directional signals generated by the computer into the required current signals for the<br />
stepper motors. In addition, a processor communicates with various other devices, such as<br />
the milling transformer, the high-speed spindle interface, etc.<br />

How to control unipolar stepper motors:<br />
Type 1 causes less power consumption. The stepper<br />
motor looses torque at higher rpm.<br />
Type 2 causes higher power consumption. The stepper<br />
motor offers more torque at higher rpm.<br />
