!Terminal functions are as follows. (Default setting)

Terminal S1 ··············· Input terminal function selection 5 (S1) ￿￿￿￿=￿￿ (S1) Terminal S2 ··············· Input terminal function selection 6 (S2) ￿￿￿￿=￿￿ (S2) Terminal S3 ··············· Input terminal function selection 7 (S3) ￿￿￿￿=￿￿ (S3) Terminal RR/S4 ········ Input terminal function selection 8 (S4) ￿￿￿￿=￿￿ (S4)

!The RR/S4 terminal is set by default as an analog voltage input terminal. To use it as an input terminal for preset speed operation, turn the SW3 switch to the S4 position.

3)Using other speed commands with preset speed command

When no preset speed command is issued, the inverter accepts an input command from the operation panel or another analog input device.

Preset			Other speed commands
	Frequency setting signals from the operation			Analog signal input command

		panel		(VI/II, RR/S4, RX, AI1 and AI2)

	Entered		Not entered	Entered	Not entered

	command valid		command valid	command valid	command valid

	command valid

!The preset speed command is always given priority when other speed commands are input at the same time. !To use the RR/S4 terminal as an analog input terminal, turn the SW3 switch to the RR position. Note that this

makes it impossible to use the function assigned to S4.
