• 1: Maintain the final value after single cycle of PLC operation. The inverter will maintain the run
frequency and direction of the last step after completing one operating cycle.
• 2: Cycle operation. The inverter will operate with a new cycle from Step 1 automatically after
completing one operating cycle until receiving the stop command.
Tens: PLC operation restart mode selection after pause
• 0: Start from step 1.
• If the inverter stops during PLC operation due to the stop command, fault or power failure, the
PLC operation will start from the Step 1 next time.
• 1: Continue to operate from the step where
the inverter pauses.
• If the inverter stops during PLC operation
due to the stop command or fault, it will
record the uptime.
• When it restarts, the inverter will continue
operation from the step where it pauses
as shown in figure.
• 2: Continue to operate at the frequency
when the inverter pauses.
• When the inverter stops during PLC
operation due to the stop command or
fault, it will record not only the operated
time but also the current frequency.
• It will continue to operate at the recorded
frequency upon restart.
Note: The difference between Mode 1 and Mode 2 is that Mode 2 also memorizes the running
frequency when the inverter pauses, and the inverter will continue to operate at the frequency
upon restart.
