P2.04 Frequency lower limit deal mode

Range: 0,1【0】

0: Run at Frequency lower limit 1: Run at zero-speed.

Note:

◆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

Fig. 5-2-3.

◆If setting is 1, when reference frequency is lower than frequency lower limit, the

inverter will run at frequency lower limit first and last the delay time set by P3.22, then

run at zero-speed. As shown in Fig.5-2-4.

◆If standby function is enabled and the inverter is just in the standby operating mode,

regardless of the value of P2.04, the inverter will run at zero-speed.
