AC power input
Connect to the commercial power supply.
Do not connect anything to these terminals when using the high power factor converter (FR-
HC2) or power regeneration common converter (FR-CV).
To use Filterpack, connect the R, S, and T cables of Filterpack.
U, V, W
Inverter output
Connect a three-phase squirrel-cage motor or a dedicated IPM motor.
P/+, PR
Brake resistor connection Connect a brake resistor (FR-ABR, MRS type, MYS type) across terminals P/+ and PR.
P/+, N/-
Brake unit connection
Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV) or high
power factor converter (FR-HC2).
P/+, P1
DC reactor (Filterpack)
connection
Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
To use Filterpack, remove the jumper across the terminals P/+ and P1, then connect the P and
P1 cables of Filterpack.
Earth (Ground)
For earthing (grounding) the inverter chassis. Must be earthed (grounded).
To use Filterpack, connect the GND cable of Filterpack.

Earth (Ground)
For earthing (grounding) the Filterpack. Must be earthed (grounded).
R, S, T
Inverter power supply
Connect to R/L1, S/L2, and T/L3 of the inverter.
P, P1
DC reactor terminal
Remove the jumper across terminals P/+ and P1, and connect to the terminals P/+ and P1 of the inverter.
GND
Inverter earth (ground)
connection
Connect to the earth (ground) terminal of the inverter.

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
Multi-speed selection
Multi-speed can be selected according to the combination of RH and RM signals.
AU
Terminal 4 input selection
The terminal 4 function is available only when the AU signal is ON. (the operation with the
frequency setting signal of 4 to 20mA DC is available)
Turning ON the AU signal disables the terminal 2 (voltage input) function.
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 power
supply
Used as power supply when connecting potentiometer for
frequency setting (speed setting) from outside of the inverter.
5VDC
permissible load current 10mA

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
input (initial setting) and 0 to 10VDC.

4
Frequency setting
(current)
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum output frequency at 20mA and makes input and
output proportional. The input signal to terminal 4 is valid
only when the AU signal is ON (terminal 2 input is invalid).
Use
Pr. 267
to switch from 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).
