4. Advanced Operation
PROGRAMMABLE AC POWER SOURCE 108
 Voltage change simulation
In this simulation, the 50 Hz 100 V power source repeats the voltage change three times at 10-second
intervals, while the voltage drops to 70 % and then linearly recovers in 0.5 seconds during one cycle
as shown in Figure 4-13. For this case, set so that the total of Normal 1 and Normal 2 Step Times
becomes 10 seconds and set the repeat count to 3. Set the Trans 1 Step Time to zero (Table 4-7).
