C2-00
Simple PLC running mode
Default
0
Setting
Range
0
Stop after the Frequency inverter runs one cycle
1
Keep final values after the frequency inverter runs one cycle
2
Repeat after the frequency inverter runs one cycle
0: Stop after the frequency inverter runs one cycle
The frequency inverter stops after running one cycle, and will not start up until receiving another command.
1: Keep final values after the frequency inverter runs one cycle
The frequency inverter keeps the final running frequency and direction after running one cycle.
2: Repeat after the frequency inverter runs one cycle
The frequency inverter automatically starts another cycle after running one cycle, and will not stop until receiving the
stop command.
Simple PLC can be either the frequency source or V/F separated voltage source.
When simple PLC is used as the frequency source, whether parameter values of C1-00 ~ C1-15 are positive or
negative determines the frequency inverter running direction. If the parameter values are negative, it indicates that the
frequency inverter runs in reverse direction.

PLC record of power failure indicates that the frequency inverter memorizes the PLC running stage and running
frequency before power failure, and frequency inverter will continue to run from the memorized stage after it is
powered on again. If the unit's digit is set to 0, the frequency inverter restarts the PLC process after it is powered
