In fig. 17 the block diagram of a closed loop system

is reported.

If the step execution is recognized by a movement

detector that uses either a slotted disk or the motor

velocity coils, two logic signals (x,y) like those re-

ported in fig. 18 are available.

Figure 17. Closed Loop System.

Figure 18. Signal Output of the Movement Detector.

Figure 19. Suggested Logic to Close the Loop.

It is possible, by using these two signals as inputs

(x, y) of the very simple and inexpensive logic circuit

reported in fig. 19, to detect the direction of rotation

and the step execution. The output of the circuit is

then used to condition the step enable input of the

GS-C module allowing the step clock pulse to be

issued only if the previous step has been executed.
