Terminal Name
AC power input Connect to the commercial power supply.
Inverter output Connect a three-phase squirrel-cage motor.
Power supply for control Connected to the AC power supply terminals R/L1 and S/L2. To retain the alarm display and
circuit alarm output, apply external power to this terminal.
Connect the brake unit (FR-BU, BU, MT-BU5), power regeneration common converter (FR-
Brake unit connection
CV), power regeneration converter (MT-RC) or high power factor converter (FR-HC, MT-HC).
For the 55K or less, remove the jumper across terminals P/+ - P1 and connect the DC reactor.
DC reactor connection
(For the 75K or more, a DC reactor is supplied as standard.)
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).
Turn on the STF signal to start forward rotation and turn it off to

stop.
Turn on the STR signal to start reverse rotation and turn it off to
Reverse rotation start
stop.
Start self-holding
Turn on the STOP signal to self-hold the start signal.
selection
Multi-speed selection Multi-speed can be selected according to the combination of RH, RM and RL signals.
Turn on the JOG signal to select Jog operation (initial setting) and turn on the start signal (STF
Jog mode selection
or STR) to start Jog operation.
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.
Turn on the MRS signal (20ms or more) to stop the inverter output.
Output stop
Use to shut off the inverter output when stopping the motor by electromagnetic brake.
Used to reset alarm output provided when protective function is activated. Turn on the RES
Reset signal for more than 0.1s, then turn it off.
Recover about 1s after reset is cancelled.
Terminal 4 is made valid only when the AU signal is turned on. (The frequency setting signal
Terminal 4 input selection can be set between 4 and 20mADC.)
Turning the AU signal on makes terminal 2 (voltage input) invalid.
AU terminal is used as PTC input terminal (thermal protection of the motor). When using it as
PTC input
PTC input terminal, set the AU/PTC switch to PTC.
Selection of automatic
restart after When the CS signal is left on, the inverter restarts automatically at power restoration. Note that
instantaneous power restart setting is necessary for this operation. In the initial setting, a restart is disabled.
failure
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.
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
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.
When connecting the frequency setting potentiometer at an initial

status, connect it to terminal 10.
supply
Change the input specifications when connecting it to terminal 10E.
Inputting 0 to 5VDC (or 0 to 10V, 4 to 20mA) provides the maximum output frequency at 5V
(10V, 20mA) and makes input and output proportional. Use Pr.73 to switch from among input 0

to 5VDC (initial setting), 0 to 10VDC, and 4 to 20mA.
(voltage)
Voltage input: Input resistance 10kΩ ± 1kΩ Maximum permissible voltage 20VDC
Current input: Input resistance 250Ω ± 2% Maximum permissible current 30mA
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
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
Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal 2 or 4 frequency setting

auxiliary
Input resistance 10kΩ ± 1kΩ, Maximum permissible voltage ± 20VDC
Frequency setting Common terminal for frequency setting signal (terminal 2, 1 or 4) and analog output terminal
common AM. Do not earth (ground).
