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 con-
nector to the connector pin of the desired control logic.
The jumper connector is in the sink logic (SINK) when shipped from the factory.
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)
CAUTION
Make sure that the jumper connector is installed correctly.
Never change the control logic while power is ON.
2.4.5 When supplying 24 V external power to the control circuit
Connect a 24 V external power supply across terminals +24 and SD. Connecting a 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 converter unit's main circuit power supply. When the main circuit power supply is
turned ON, the power supply changes from the 24 V external power supply to the main circuit power supply.
During the 24 V external power supply operation, the ALARM lamp of the accessory cover flickers. When the operation
panel (FR-DU08) is installed, "EV" flickers.
