3: consecutive circulation. As shown in Fig.6-24，the inverter start next
circle automatically after finishing a circle，until there is stop command.

nd
bit:
0: start from first step. Stop during running caused by stop command,
failure or power off，after restarting the inverter will run from first step.
1: continue to run from step frequency of interruption moment. When
stop during running caused by stop command or failure，the inverter will record
current step used time automatically and enter into this step automatically after
restarting，continue to run for residual time according to defined frequency of this
step, as shown in Fig.6-25. The inverter will rerun from first step after restarting if
power off.

bit : PLC run time unit
0: second；1: minute
This unit is only effective to PLC run step time，for accelerating decelerating
time of PLC run period, their unit selection is determined by F0.07.

bit
0: power off no memory
1: the inverter still in the memory running state when the power off, it needs
renew run (terminal control exceptional) when power on without automotive start.
Make memory of the simple PLC running segments, speed and running time
before power off. Automotive read the state of the power off when restart, but the
inverter doesn’t run directly, (control commands except for the terminal mode),
