[Appendix] Operation of Drive and Options during Operation of the External 24 V Power Supply
The following table summarizes operation of the drive and options when the main circuit power supply is OFF and
external 24 V power supply is being provided to terminals PS-AC.
Can be operated in the same way as when the main
circuit power supply is ON.
Note that oPr [Keypad Connection Fault] is not
detected.
Operates in the same way as when the main circuit
power supply is ON.
Operation differs according to the software version.
Communications by
Communication Option,
MEMOBUS/Modbus
Communication Terminal
Operates in the same way as when the main circuit
power supply is ON.
Multi-Function Analog Input
Operates in the same way as when the main circuit
power supply is ON.
Multi-Function Analog Output
Operates in the same way as when the main circuit
power supply is ON.
Multi-Function Digital Input
Does not operate when the main circuit power supply
of the drive is OFF.
Provide the external 24 V
power supply to the
multi-function input
selection common terminal
(SC).
*1
Multi-Function Digital Output
Operates in the same way as when the main circuit
power supply is ON.
Operation of the multi-function digital output terminal
and fault relay output terminal to which fault [H2-xx
= E, 10E] is set differs according to the software
version.
Multi-Function Photocoupler
Output
Fault Relay Output Terminal
Operates in the same way as when the main circuit
power supply is ON.
Operates in the same way as when the main circuit
power supply is ON.
PG Option Speed Detection
(PG-B3, PG-X3, PG-F3,
PG-RT3)
Does not operate when the main circuit power supply
of the drive is OFF.
PG option-related fault detection operation differs
according to the software version.
Turn ON the main circuit
power supply of the drive
when using a PG option.
Operates in the same way as when the main circuit
power supply is ON.
