P8 – Simple PLC and Multispeed parameters
P8-00
Program run
mode
0: Disabled
1: Program stops after running for one cycle
2: Program runs for one cycle and
then continues at last operating frequency
3: Circulatory running of the program
Default: 0
1: The program runs once and then the operation stops.
3: The program runs in a cyclic sequence continuously till deliberately stopped.
This parameter selects how the Simple PLC program will run0: Simple PLC operation is disabled.
2: The program runs once and then continues operating at the last
frequency in the sequence.

These parameters determine the time for which the frequencies set in P8-01 to P8-07 will be running.
The operation is as shown in the timing diagram below.
