When supplying 24 V external power to the control circuit
Connect a 24 V external power supply across terminals +24 and SD. Connecting a 24 V external power supply enables I/O terminal ON/OFF operation, operation panel displays, control functions, and communication during communication operation even at power-OFF 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
• When the 24 V external power is supplied while the main circuit power supply is OFF, 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
. (For the details of Pr.30
, refer to the FR-F800 Instruction Manual (Detailed).))
Confirming the 24 V external power supply input
• During the 24 V external power supply operation, the 24 V external power supply operation (EV) signal 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.
