Symbol
Terminal Name Description
Main circuit
R/L1, S/L2,
T/L3 *
AC power input
Connect to the commercial power supply. Keep these terminals open when using the high
power factor converter (FR-HC) or power regeneration common converter (FR-CV).
When using single-phase power input, terminals are R/L1 and S/L2.
U, V, W Inverter output Connect a three-phase squirrel-cage motor.
P/+, PR Brake resistor connection
Connect a brake resistor (MRS type, MYS type, FR-ABR) across terminals P/+ and PR.
(The brake resistor can not be connected to the 0.1K or 0.2K)
P/+, N/-
Brake unit connection
Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV) or high
power factor converter (FR-HC).
DC power input
Connect the plus side of the power supply to terminal P/+ and minus side to terminal N/-.
P/+, P1 * DC reactor connection
Remove the jumper across terminals P/+ and P1 and connect a DC reactor. Single-phase
100V power input model is not compatible with DC reactor.
Terminal P1 is not available for single-phase 100V power input model.
Earth (Ground) For earthing (grounding) the inverter chassis. Must be earthed (grounded).
Control circuit/input signal
Contact input
STF Forward rotation start
Turn ON the STF signal to start forward rotation and turn it OFF
to stop.
When the STF and STR
signals are turned ON
simultaneously, the stop
command is given.
STR Reverse rotation start
Turn ON the STR signal to start reverse rotation and turn it OFF
to stop.
RH, RM, RL Multi-speed selection
Multi-speed can be selected according to the combination of RH, RM and RL signals.
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.
RES Reset
Used to reset alarm output provided when protective circuit is activated. Turn ON the RES
signal for more than 0.1s, then turn it OFF. Initial setting is for reset always. By setting Pr. 75,
reset can be set to enabled only at fault occurrence. Recover about 1s after reset is cancelled.
SD
Contact input common
(sink) (initial setting)
Common terminal for contact input terminal (sink logic) and terminal FM.
External transistor
common (source)
Connect this terminal to the power supply common terminal of a transistor output (open
collector output) device, such as a programmable controller, in the source logic to avoid
malfunction by undesirable current.
24VDC power supply
common
Common output terminal for 24VDC 0.1A power supply (PC terminal).
Isolated from terminals 5 and SE.
PC
External transistor
common
(sink) (initial setting)
Connect this terminal to the power supply common terminal of a transistor output (open
collector output) device, such as a programmable controller, in the sink logic to avoid
malfunction by undesirable current.
Contact input common
(source)
Common terminal for contact input terminal (source logic).
24VDC power supply Can be used as 24VDC 0.1A power supply.
Frequency setting
10
Frequency setting power
supply
Used as power supply when connecting potentiometer for
frequency setting (speed setting) from outside of the inverter.
5VDC
permissible load current 10mA
2
Frequency setting
(voltage)
Inputting 0 to 5VDC (or 0 to 10V) provides the maximum output
frequency at 5V (10V) and makes input and output
proportional. Use Pr. 73 to switch between input 0 to 5VDC
(initial setting) and 0 to 10VDC input.
Input resistance 10k ± 1k
Permissible maximum voltage
20VDC
4
Frequency setting
(current)
Inputting 0 to 20mADC (or 0 to 5V / 0 to 10V) provides the
maximum output frequency at 20mA and makes input and
output proportional. This input signal is valid only when the AU
signal is ON (terminal 2 input is invalid). To use terminal 4
(initial setting is current input), set "4" to any of Pr.178 to Pr.184
(input terminal function selection), and turn AU signal ON. Use
Pr. 267 to switch among input 4 to 20mA (initial setting), 0 to
5VDC, and 0 to 10VDC. Set the voltage/current input switch in
the "V" position to select voltage input (0 to 5V/0 to 10V).
Voltage input:
Input resistance 10k ± 1k
Permissible maximum voltage
20VDC
Current input:
Input resistance 233 ± 5
Maximum permissible current
30mA.

Frequency setting
common
Common terminal for the frequency setting signals (terminals 2 and 4). Do not earth (ground).
