the inverter will be run after power resumes normal.
Note: To ensure this function is valid under terminal operating command reference mode, please do not
change the status of operating command terminal during shutdown.
When the inverter operates, the function can response the setting of reference channel for other
frequencies after using the pre-set frequency as the setting frequency and keeping the time as pre-set
frequency operating time Pb.18.

Fig. 6-35 Upper and lower limit of zero frequency operation
This function supports sleep function and energy saving operation. After running, the inverter will start
when the setting frequency
≥Pb.19. During operation, the inverter operates at zero frequency
when the
setting frequency
≤Pb.20. Proper setting of limit value of zero operation can avoid the inverter starting
and stopping frequently. If the inverter is often used for work situations such as air condition and fan,
change the analog signal of temperature sensor to setting frequency to control automatic starting or
stopping of inverter. See Fig. 6-35.
