Toshiba VF-AS1 instruction manual Functions of input terminals in case of sink logic, LI1~LI8

! E6581301

7.2Applied operation with input and output signals (operation by terminal board)

7.2.1Functions of input terminals (in case of sink logic)

Use the above parameters to send signals from an external programmable controller to various control input terminals to operate and/or set the inverter.

The desired contact input terminal functions can be selected from 120 types. This gives system design flexibility. [Control terminal board]

■Setting of contact input terminal function

	Terminal	Title		Function			Adjustment	Default setting
	symbol						range
	-	￿￿￿￿ [Note 5],		Always ON function selection 1~3				￿￿(No function is
		￿￿￿￿, ￿￿￿￿￿						assigned)
	F	￿￿￿￿￿		Input terminal function selection	1	(F)		￿￿(Forward run)
	R	￿￿￿￿￿		Input terminal function selection	2	(R)	￿~￿￿￿	￿￿(Reverse run)
	ST	￿￿￿￿ [Note 6], ￿￿￿￿￿		Input terminal function selection	3	(ST)		￿￿(Standby)
	RES	￿￿￿￿￿		Input terminal function selection	4	(RES)	￿ Refer to	￿ (Reset)
	S1	￿￿￿￿￿		Input terminal function selection	5	(S1)	Section	￿￿ (Preset speed 1)

	S2	￿￿￿￿￿		Input terminal function selection	6	(S2)	7.2.1.	￿￿￿(Preset speed 2)
	S3	￿￿￿￿￿		Input terminal function selection	7	(S3)		￿￿￿(Preset speed 3)
	RR/S4	￿￿￿￿￿		Input terminal function selection	8	(RR/S4)		￿￿￿(Preset speed 4)￿
	LI1~LI8	￿￿￿￿~￿￿￿￿￿		Input terminal function selection	9~16			￿
	B12~B15	￿￿￿￿~￿￿￿￿		Input terminal function selection 17~20				￿￿
	Note 1:RR/S4 terminal become enable when SW3 is switch to S4.
	Note 2: When ￿￿￿￿, ￿￿￿￿ and ￿￿￿￿ (Always ON function selection 1~3) are selected, selected function is
		generally activated regardless of positive or negative logic.
	Note 3: ￿￿￿￿~￿￿￿￿ is for use of expansion terminal board option unit.
	Note 4: ￿￿￿￿~￿￿￿￿ is not supported (for options).
	Note 5: VFAS1-****-WN, HN		Note 6: VFAS1-****-WP

■Connection method (An example of the connection of terminals: SW1 set to sink logic)

1) In case of positive logic (a-contact) input

￿ Inverter A-contact switch

Input terminal

CC

!This function is activated when the input terminal and CC (common) are short-circuited. Use this function to specify forward/reverse run or a preset speed operation.

2) In case of negative logic (b-contact) input

￿Inverter
		B-contact switch
	Input terminal

CC

!This function is activated when the input terminal and CC (common) are open-circuit. Use this function to specify operation standby signal or reset signal.
