Application parameter group 10
PARAMETER DESCRIPTION 225
Note: 1. When the motor runs at 50Hz (or 60Hz), the commercial power supply will offer a more efficient operation than
the inverter will. Moreover, during the inverter maintenance/inspection period, the commercial power supply
circuit should be installed to prevent the motor from being stopped for too long.
2. To prevent the inverter from setting off the over-current alarm when changing between the inverter operation
and the commercial power supply operation, the interlock measure has to be taken. Once the motor stops, it will
be activated via the inverter. Switchover and interlock can be carried out through the inverter and a complicated
commercial power supply if commercial power supply switchover sequence function that can send out the signal
for electromagnetic contactor actions is used.
3. This function is only valid under the V/F mode 00-21(P.300)=0.
5.11.12 When input power fail stop function
 When the inverter power comes to a sudden failure, regenerative power can maintain the inverter output to
deceleration stop.
