Figure 5.1.2.1: Moving inside a menu ......................................................................................................................................2
Figure 5.3.6.1: Above: Actual spd; Below: Motor current. Speed P too low. ..........................................................................45
Figure 5.3.6.3: Above: Actual spd; Below: Motor current. Speed I too high. ..........................................................................45
Figure 5.3.6.2: Above: Actual spd; Below: Motor current. Speed P too high. ..........................................................................45
Figure 5.3.6.4: Above: Actual spd; Below: Motor current. Speed P and Speed I set correctly. ...............................................45
Figure 5.3.6.5: Above: Flux reference; Below: Flux current. The regulator behavior is not good. Jumps are due to field chan-

ging. ..................................................................................................................................................................................46

Figure 5.3.6.7: Above: Flux reference; Below: Flux current. The increment in the field current has no jump. Variation compa-

red to Fig. 4.5.7: Increase of Flux P from 2 to 10%. Flux I = 5%. ......................................................................................46

Figure 5.3.6.6: Above: Flux reference; Below: Flux current. The reduction of the field current depends on the field time con-

stant. The reg has no influence. ........................................................................................................................................46

Figure 5.3.6.8: Above: Flux; Below: Output voltage. After a speed change the field current (Flux) has some jumps. Voltage P

= 10%, Voltage I = 80%. .................................................................................................................................................48

Figure 5.3.6.10: Above: Flux; Below: Output voltage. After a short transient, the field current and armature voltage are con-

stant. Voltage P = 40%, Voltage I = 50%. ........................................................................................................................48

Figure 5.3.6.9: Above: Flux; Below: Output voltage. The gain is too low. The armature voltage increases. Voltage P = 3%,

Voltage I = 5%. .................................................................................................................................................................48

Figure 5.3.7.2: Blocks diagrams of field current regulator ......................................................................................................50
Figure 5.3.7.3: Above: Actual spd; Below: Motor current jumps with the speed changes due to a high moment of inertia. The

function Speed-up is not active. ........................................................................................................................................51
