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 converter unit 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 converter unit, then the power supply changes to the main circuit power supply.
Confirming the 24 V external power supply input
• During 24 V external power supply operation, the ALARM LED of the accessory cover blinks. When the operation panel
(FR-DU08) is installed, "EV" blinks.

POWER ALARM
• During 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 any of Pr.190 to Pr.195 (Output terminal function selection)
to assign the function to the output terminal.
Operation while the 24 V external power is supplied
• Fault records and parameters can be read and parameters can be written using the operation panel keys.
• During the 24 V external power supply operation, the monitor items and signals related to inputs to main circuit power
supply, such as input current and converter output voltage, are invalid.
• The alarms, which have occurred when the main circuit power supply is ON, continue to be output after the power supply
is changed to the 24 V external power supply. Perform the converter reset or turn OFF then ON the power to reset the
faults.
