Note: 1. Output frequency is limited by the upper and lower frequency limits in triangular wave operation.
2. If the values of amplitude compensation 10-25(P.236) and 10-26(P.237), are too large, overvoltage trip and stall
prevention protection will trigger.
3. This function is only valid in V/F mode (00-21(P.300)=0).
5.11.11 Switch to commercial power supply function
 Inverter has built-in switch to commercial power supply function. Magnetic contactor for switching can be
conveniently used by inputting start, stop and automatic switching signal.

After switching from inverter operation to commercial power
supply operation, after inverter start command (STF/STR) is
OFF, switch to inverter operation, and slow down to stop.
Switch to commercial supply function

10-31(P.249) sets the frequency for switching from inverter operation to commercial supply. From start-up to
10-31(P.249) inverter operation, the output frequency is above 10-31(P.249) value, automatically switching to
commercial supply. 10-31(P.249) set to 99999, without automatic switching.

If 10-32(P.250)≠99999, 10-31(P.249)≠99999 will be valid at automatic switching operation. After switching from
inverter operation to commercial supply, if frequency command is lower than (10-31(P.249)~10-32(P.250)), it will
