E6581301

Voltage/current switching by means of an external terminal

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.

Frequency setting with operation panel and operation with terminal board

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.

Frequency setting and operation with operation panel:

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 RUN and STOP keys to perform operation control.

•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).

[Programmed value]
￿:	Terminal board operation	ON and OFF of an external signal Runs and stops operation.
￿:	Operation panel operation	Press the	RUN and STOP keys on the operation panel to Run and stop
		a run. (including LED/LCD option input)
￿:	2-wire RS485 communication operation		Run and stop commands are entered from the
			2-wire RS485 communications device.
			(Communication No.: FA00)
￿:	4-wire RS485 communication operation		Run and stop commands are entered from the 4-wire
			RS485 communications device.
			(Communication No.: FA04)
￿:	Communication option input enabled		Signals from an optional communication device are used to
			start and stop operation.

￿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 ￿￿￿￿, 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
