Fig. 6-63 PLC continuous cycle mode
Tens place: The restart mode selection for interrupted PLC running
0: Restart from the first section
If it is stopped (caused by stopping command, fault or power down) during operation, it will operate from
the first section after restarting.
1: Continue to run from the stage frequency of the stop (fault) moment
If it is stopped (caused by a stopping command or fault) during operation, the drive will automatically
record the running time of the current stage and enter this stage after restarting, and it will complete the
remaining running time at the set frequency of this stage, as shown in Fig. 6-64:

2: Continue to run from the running frequency of the stop (or fault) moment
If it is stopped (caused by a stopping command or fault) during operation, the drive will not only
automatically record the current running time but also the running frequency of the stop moment, when
restarted, it will be restored to the running frequency of the stop moment, and then continue the
remaining running time, as shown in Fig. 6-65.
Note
The difference between the mode 1 and 2 is that latter can record the running frequency of the stop moment,
and continue to run from this frequency after restarting.
