2.6.6 When supplying 24 V external power to the control circuit
Connect the 24 V external power supply across terminals +24 and SD to turn the I/O terminal ON/OFF operation, keep the
operation panel ON, and carry out communication with other devices even at power-OFF state of inverter's main circuit power
supply. When the main circuit power supply is turned ON, the power supply source changes from the 24 V external power
supply to the main circuit power supply.

 Starting and stopping the 24 V external power supply operation
• Supplying 24 V external power while the main circuit power is OFF starts the 24 V external power supply operation.
Likewise, turning OFF the main circuit power while supplying 24 V external power starts the 24 V external power supply
operation.
• Turning ON the main circuit power stops the 24 V external power supply operation and enables the normal operation.
NOTE
• During the 24 V external power supply operation, the inverter operation is disabled.
• In the initial setting, when the main power supply is turned ON during the 24 V external power supply operation, a reset is
performed in the inverter, then the power supply changes to the main circuit power supply. (The reset can be disabled using
Pr.30. (Refer to page 553.))
 Confirming the 24 V external power supply input
• During the 24 V external power supply operation, the alarm lamp flickers.
• During the 24 V external power supply operation, the 24 V external power supply operation signal (EV) is output. To use
the EV signal, set "68 (positive logic) or 168 (negative logic)" in one of Pr.190 to Pr.196 (Output terminal function
selection) to assign function to an output terminal.
