P2.04 Frequency lower limit deal mode
0: Run at Frequency lower limit
2: Stopping
Notes:

If setting is 0, when the reference frequency is lower than frequency lower limit, the inverter will run at
frequency lower limit instead of reference frequency. As shown in Figure. 5-2-3.
 Option 1: When the inverter runs at 0 frequency, if the set frequency is less than the lower limit frequency, the
inverter should run at the lower limit frequency, and run at 0 frequency after the delay time arrives at P3.30,
as shown in Fig. 5-2-4.
 Sleep function is enabled and the inverter is in sleep running, then no matter P2.04 is 0 or 1, the inverter
should be regarded as running at 0 frequency.
 Option 3: Reserve
