4.4 Using the Sequence Function
EC1000SA 4-40
4.4.6 Example of sequence operation settings
The following describes the steps for setting a new sequence operation, based on the sequence transition
example described in
Table4-12
. The time unit is seconds (s). (
See “5.6.5 Time unit setting”
to
change the time unit.)

Step Number 1 2 3 4 5 6
Step time (TIME) 0.1 0.2 0.1 0.2 0.2 0.3
DC voltage (DC VOLT) 25. 0 75. 0 75. 0 50. 0 100. 0 0.0
DC voltage operation type SWEEP KEEP CONST SWEEP SWEEP SWEEP
Step end (STEP TERM) CONT CONT CONT CONT CONT STOP

Jump times (JUMP NUM) 1 1 1 1 1 1
Branch 0 (BRANCH0) 0 0 0 0 6 0
Though the DC voltage of step 2 is set to 75.0 V, the output DC voltage will be 25.0 V which is succeeded
from the previous step (step 1) because the DC operation type of step 2 is set to KEEP. After executing
step 4, the sequence will jump to step 2 because the jump step of step 4 is set to 2 (<1> in
Figure 4-13
).
The output DC voltage will be kept to 50.0 V coming from the previous step (step 4) because the DC
operation type of step 2 is set to KEEP. The jump times of step 4 is set to 1, so the sequence will move to
the next step (= step 5) after jumping once and executing step 4 (<2> in
Figure 4-13
). The step time of
step 5 is set to 0.2 s and the branch 0 jump step of step 5 is set to step 6, so the sequence will immediately
move to step 6 when the branch 0 is input within the step time (<3> in
Figure 4-13
).
