Three-wire Interface Operation

The 3-wire interface is an industry standard motor control interface. This function uses two inputs for momentary contact start/stop control, and a third for selecting forward or reverse direction. To implement the 3-wire interface, assign 20 [STA] (Start), 21 [STP] (Stop), and 22 [F/R] (Forward/Reverse) to three of the intelligent input terminals. Use a momentary contact for Start and Stop. Use a selector switch, such as SPST for the Forward/Reverse input. Be sure to set the operation command selection A002=01 for input terminal control of motor.

If you have a motor control interface that needs logic-level control (rather than momentary pulse control), use the [FW] and [RV] inputs instead.

	Option	Terminal	Function Name	State	Description
	Code	Symbol	Function Name	State	Description
	Code	Symbol
	20	STA	Start Motor	ON	Start motor rotation on momentary contact (uses
					acceleration profile)
				OFF	No change to motor operation
	21	STP	Stop Motor	ON	No change to motor operation
				OFF	Stop motor rotation on momentary contact (use
					deceleration profile)
	22	F/R	Forward/Reverse	ON	Select reverse direction of rotation
				OFF	Select forward direction of rotation

Valid for inputs:	C001~C005
Required settings	A002 = 01
Notes:

•The STP logic is inverted. Normally the switch will be closed, so you open the switch to stop. In this way, a broken wire causes the motor to stop automatically (safe design).

•When you configure the inverter for 3-wire interface control, the dedicated [FW] terminal is automatically disabled. The [RV] intelligent terminal assignment is also disabled.

Example (default input configuration shown—see
page 3–49):	STP STA
F/R	STP STA

See I/O specs on page 4–6.

Operations and Monitoring

The diagram below shows the use of 3-wire control. STA (Start Motor) is an edge-sensitive input; an OFF-to-ON transition gives the Start command. The control of direction is level- sensitive, and the direction may be changed at any time. STP (Stop Motor) is also a level- sensitive input.
