Terminal Name
Connect to the commercial power supply.
Do not connect anything to these terminals when using the high power factor converter (FR-
AC power input
HC2) or power regeneration common converter (FR-CV).
To use Filterpack, connect the R, S, and T cables of Filterpack.
Inverter output
Connect a three-phase squirrel-cage motor or a dedicated IPM motor.
Connect a brake resistor (FR-ABR, MRS type, MYS type) across terminals P/+ and PR.
Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV) or high
Brake unit connection
power factor converter (FR-HC2).
Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
DC reactor (Filterpack)
To use Filterpack, remove the jumper across the terminals P/+ and P1, then connect the P and
connection
P1 cables of Filterpack.
For earthing (grounding) the inverter chassis. Must be earthed (grounded).
Earth (Ground)
To use Filterpack, connect the GND cable of Filterpack.
Commercial power
Connect to the commercial power supply.
supply input
Earth (Ground)
For earthing (grounding) the Filterpack. Must be earthed (grounded).
Inverter power supply
Connect to R/L1, S/L2, and T/L3 of the inverter.
DC reactor terminal
Remove the jumper across terminals P/+ and P1, and connect to the terminals P/+ and P1 of the inverter.
Inverter earth (ground)
Connect to the earth (ground) terminal of the inverter.
connection
Turn ON the STF signal to start forward rotation and turn it
Forward rotation start
OFF to stop.
Turn ON the STR signal to start reverse rotation and turn it
Reverse rotation start
OFF to stop.
Multi-speed selection
Multi-speed can be selected according to the combination of RH and RM signals.
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.
Contact input common
Common terminal for contact input terminal (sink logic) and terminal FM.
(sink) (initial setting)
Connect this terminal to the power supply common terminal of a transistor output (open
External transistor
collector output) device, such as a programmable controller, in the source logic to avoid
common (source)
malfunction by undesirable current.
24VDC power supply
Common output terminal for 24VDC 0.1A power supply (PC terminal).
common
Isolated from terminals 5 and SE.
External transistor
Connect this terminal to the power supply common terminal of a transistor output (open
common (sink)
collector output) device, such as a programmable controller, in the sink logic to avoid
malfunction by undesirable current.

Contact input common
Common terminal for contact input terminal (source logic).

24VDC power supply
Can be used as 24VDC 0.1A power supply.
Frequency setting power
Used as power supply when connecting potentiometer for
supply
frequency setting (speed setting) from outside of the inverter.
Inputting 0 to 5VDC (or 0 to 10V) provides the maximum
Frequency setting
output frequency at 5V (10V) and makes input and output
(voltage)
proportional. Use Pr. 73 to switch between input 0 to 5VDC
input (initial setting) and 0 to 10VDC.
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
Frequency setting
only when the AU signal is ON (terminal 2 input is invalid).
(current)
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).
Frequency setting
Frequency setting signal (terminal 2 or 4) common terminal. Do not earth (ground).
common
For connecting PTC thermistor output.
PTC thermistor input
When PTC thermistor protection is valid (Pr. 561 "9999"),
terminal 2 is not available for frequency setting.

are turned ON simultaneously,
the stop command is given.
