2.4.4 Control logic (sink/source) change
Change the control logic of input signals as necessary.
To change the control logic, change the jumper connector position on the control circuit board. Connect the jumper connector to
the connector pin of the desired control logic.
O
The control logic of input signals is initially set to the sink logic (SINK) for the FM type.
O
The control logic of input signals is initially set to the source logic (SOURCE) for the CA type.
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)
2.4.5 When supplying 24 V external power to the control circuit
Connect the 24 V external power supply across ter24 and SD. The 24 V external power supply enables I/O terminal ON/
OFF operation, operation panel displays, control functions, and communication during communication operation even during
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.
During the 24 V external power supply operation, "EV" blinks on the operation panel.

CAUTION
O
Make sure that the jumper connector is installed correctly.
O
Never change the control logic while power is ON.
