 Repeat (Repeat)
You can set to repeat the simulation in a series from the Normal 1 step to the Normal 2 step. Specify
the ON or OFF of repeat and the repeat count. When Repeat is set to ON, the simulation repeats for
the specified count. The simulation in a series is repeated for the repeat count + 1. Setting the repeat
count to zero (0) means an infinite count. When Repeat is set to OFF, this product executes the
simulation only once and finishes it without performing the repeat operation.
4.3.3 Output Examples Using Simulation Function
 Voltage dip simulation
In this simulation, the 50 Hz 100 V power source repeats a 70 % voltage dip for 0.5 seconds three
times at 10-second intervals as shown in Figure 4-12. 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 and Trans
2 Step Times to zero (Table 4-6).
