Operation When Using External 24 V Power Supply
To operate the drive, de-energize the main circuit power supply and connect an external 24 V power supply to
terminals PS-AC.

*1 When you use an external 24 V power supply, the operation of the data log function is different for different drive software versions.
On drives with software versions PRG: 09015 and later, you can continue the data log function.
Note:
The "PRG" column on the nameplate on the right side of the drive identifies the software version. You can also use U1-25
[SoftwareNumber FLASH] to identify the software version.
*2 When you use MFDI and a Digital Input option (DI-A3), wire the terminals as shown in
Wiring Digital Input Option (DI-A3) on page
*3 When you use an external 24 V power supply, the operation of the MFDO terminals are different for different drive software
versions.
Note:
The "PRG" column on the nameplate on the right side of the drive identifies the software version. You can also use U1-25
[SoftwareNumber FLASH] to identify the software version.
• Drive software versions PRG: 01028 and later
When the main circuit power supply of the drive turns off, and you remove the cause of a fault and do a fault reset from the
keypad, the fault relay output terminals and the MFDO terminals set for H2-xx = E, 10E [Fault] will change status.
• Drive software versions PRG: 01027 and earlier
When the main circuit power supply of the drive turns off, remove the cause of a fault and do a fault reset from the keypad. The
fault relay output terminals and the MFDO terminals set for H2-xx = E, 10E [Fault] will keep the same status as before the main
circuit power supply of the drive turned off. The fault code shown on the keypad will disappear.

Operation
The keypad operates the same as when the main circuit power supply
is ON. The drive will not detect oPr [Keypad Connection Fault].
The data log function operates the same as when the main circuit
power supply is ON.
The operation is different for different drive software versions.
Communication operates the same as when the main circuit power
supply is ON.
MFAI operates the same as when the main circuit power supply is
ON.
MFAO operates the same as when the main circuit power supply is
ON.
MFDI does not operate when the main circuit power supply of the
drive is OFF.
MFDO operates the same as when the main circuit power supply is
ON.
The operations of MFDO terminals and fault relay output terminals
set for H2-xx = E [Fault] are different for different drive software

Pulse train input operates the same as when the main circuit power
supply is ON.
Pulse train output operates the same as when the main circuit power
supply is ON.
Encoder options do not operate when the main circuit power supply of
the drive is OFF.
The operation to detect encoder option-related faults is different for
different software versions.
Analog input options operate the same as when the main circuit power
supply is ON.
Analog output options operate the same as when the main circuit
power supply is ON.
The operation is different for different drive software versions.
