Terminal Specification Explanation

Type		Terminal Symbol	Terminal Name	Description
		R/L1, S/L2, T/L3	AC power input	Connect to the commercial power supply.
		U, V, W	Inverter output	Connect a three-phase squirrel-cage motor.
		R1/L11, S1/L21	Power supply for control	Connected to the AC power supply terminals R/L1 and S/L2. To retain the alarm display and
circuit			circuit	alarm output, apply external power to this terminal.
		P/+, N/-	Brake unit connection	Connect the brake unit (FR-BU, BU, MT-BU5), power regeneration common converter (FR-
				CV), power regeneration converter (MT-RC) or high power factor converter (FR-HC, MT-HC).
Main
		P/+, P1	DC reactor connection	For the 55K or less, remove the jumper across terminals P/+ - P1 and connect the DC reactor.
				(For the 75K or more, a DC reactor is supplied as standard.)
		PR, PX	Please do not remove or use terminals PR and PX or the jumper connected.
			Earth (Ground)	For earthing (grounding) the inverter chassis. Must be earthed (grounded).
		STF	Forward rotation start	Turn on the STF signal to start forward rotation and turn it off to	When the STF and STR
				stop.	signals are turned on
		STR	Reverse rotation start	Turn on the STR signal to start reverse rotation and turn it off to	simultaneously, the stop
				stop.	command is given.
		STOP	Start self-holding	Turn on the STOP signal to self-hold the start signal.
			selection
		RH, RM, RL	Multi-speed selection	Multi-speed can be selected according to the combination of RH, RM and RL signals.
		JOG	Jog mode selection	Turn on the JOG signal to select Jog operation (initial setting) and turn on the start signal (STF
				or STR) to start Jog operation.
		RT	Second acceleration/	Turn on the RT signal to select second acceleration/deceleration time.
			deceleration time	When the second function such as "second torque boost" and "second V/F (base frequency)"
			selection	are set, turning on the RT signal selects these functions.
		MRS	Output stop	Turn on the MRS signal (20ms or more) to stop the inverter output.
				Use to shut off the inverter output when stopping the motor by electromagnetic brake.
	input
				Used to reset alarm output provided when protective function is activated. Turn on the RES
		RES	Reset	signal for more than 0.1s, then turn it off.
	Contact			Recover about 1s after reset is cancelled.
			Terminal 4 input selection	Terminal 4 is made valid only when the AU signal is turned on. (The frequency setting signal
				can be set between 4 and 20mADC.)
		AU		Turning the AU signal on makes terminal 2 (voltage input) invalid.
			PTC input	AU terminal is used as PTC input terminal (thermal protection of the motor). When using it as
				PTC input terminal, set the AU/PTC switch to PTC.
signal
			Selection of automatic	When the CS signal is left on, the inverter restarts automatically at power restoration. Note that
		CS	restart after
input			instantaneous power	restart setting is necessary for this operation. In the initial setting, a restart is disabled.
			failure
circuit		SD	Contact input common	Common terminal for contact input terminal (sink logic) and terminal FM. Common output
			(sink)	terminal for 24VDC 0.1A power supply (PC terminal). Isolated from terminals 5 and SE.
Control			External transistor	When connecting the transistor output (open collector output), such as a programmable
			common,	controller (PLC), when sink logic is selected, connect the external power supply common for
		PC	24VDC power supply,	transistor output to this terminal to prevent a malfunction caused by undesirable currents. Can
			contact input common	be used as 24VDC 0.1A power supply. When source logic has been selected, this terminal
			(source)	serves as a contact input common.

				Inputting 0 to 5VDC (or 0 to 10V, 4 to 20mA) provides the maximum	output frequency at 5V
		2	Frequency setting	(10V, 20mA) and makes input and output proportional. Use Pr.73 to switch from among input 0

	Frequency			Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the maximum output frequency at 20mA
				(5V, 10V) makes input and output proportional. This input signal is valid only when the AU
		4	Frequency setting	signal is on (terminal 2 input is invalid). Use Pr.267 to switch between the input 4 to 20mA and 0
			(current)	to 5VDC, 0 to 10VDC (initial setting).
				Voltage input: Input resistance 10kΩ ± 1kΩ Maximum permissible voltage 20VDC
				Current input: Input resistance 250Ω ± 2% Maximum permissible current 30mA
			Frequency setting	Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal 2 or 4 frequency setting
		1		signal. Use Pr.73 to switch between the input 0 to ±5VDC and 0 to ±10VDC (initial setting).
