To operate the drive, de-energize the main circuit power supply and connect an external 24 V power supply to terminals PS-AC.

 

Function

Operation

Solution

Keypad

The keypad operates the same as when the main circuit power supply is ON. The drive will not detect oPr [Keypad Connection Fault].

-

Data Log

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. 1

-

Communications by Communication Option or MEMOBUS/Modbus Communication Terminals

Communication operates the same as when the main circuit power supply is ON.

-

MFAI

MFAI operates the same as when the main circuit power supply is ON.

-

MFAO

MFAO operates the same as when the main circuit power supply is ON.

-

MFDI

MFDI does not operate when the main circuit power supply of the drive is OFF.

Connect the external 24 V power supply to MFDI selection common terminal (SC). 2

MFDO

Multi-Function Photocoupler Output

Fault Relay Output Terminal

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, 10E [Fault] are different for different drive software versions 3

-

Pulse Train Input

Pulse train input operates the same as when the main circuit power supply is ON.

-

Pulse train output

Pulse train output operates the same as when the main circuit power supply is ON.

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: 01015 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.

When you use MFDI and a Digital Input option (DI-A3), wire the terminals as shown in Wiring MFDI Terminals.

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: 01013 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: 01012 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.
