Fig.6-56 PLC start mode 1
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. 6-57.
 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.

power on.
1: Save the stage and frequency at the moment of power down
Record PLC running status upon power-down, including the stage of the power-down moment, running
frequency, and the running time. It shall be continued with the restart mode of interrupted PLC running
defined in the tens places after power-on.
