Switching between remote and local (different frequency commands) can be performed by turning on or off the S3 terminal.
In that case, apply a voltage via the RR/S4 terminal and a current via the VI/II terminal.
S3-CC OFF: The frequency is set according to the voltage applied to the RR/S4 terminal.
S3-CC ON: The frequency is set according to the current applied to the VI/II terminal.
In sink logic mode: ST-CC ON: Standby (ON (short-circuited) by default), F-CC ON: Forward run, R-CC ON: Reverse run.
This setting is used to set the frequency using the operation panel and to perform operation control using the terminal
board.
Use the and keys to set the frequency.
In sink logic mode: ST-CC ON: Standby (ON (short-circuited) by default),
F-CC ON: Forward run, R-CC ON: Reverse run.
This setting is used to set the frequency and to perform operation control, using the operation panel.
Use the and keys to set the frequency.
Use the and keys to perform operation control.

For details, refer to Instruction Manual (E6581281,
E6581343, E6581288) specified in Section 6.42.
* There are two types of function: the function that conforms to commands selected by EOQF, and the function that
conforms only to commands from the terminal board.
Refer to the table of input terminal function selection in Section 7.2.
* When priority is given to commands from a linked computer or terminal board, they have priority over the setting of
EOQF.
Voltage/current switching by means of an external terminal
Frequency setting and operation with operation panel:
• Function
These parameters are to program which command to the inverter (from operation panel, terminal board, remote
input device or options) will be given priority in running/stopping the operation and in frequency setting (speed).
