Main circuit
R/L1, S/L2, T/L3 AC power input Connect these terminals to the commercial power supply.
U, V, W Inverter output Connect a three-phase squirrel-cage motor to these terminals.
P/+, N/- Brake unit connection
Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV), or high power
factor converter (FR-HC2) to these terminals.
Earth (ground) For earthing (grounding) the inverter chassis. Be sure to earth (ground) the inverter.

STF
∗1
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
∗1
Reverse rotation start
Turn ON the STR signal to start reverse rotation and turn it
OFF to stop.
RH, RM, RL
∗1
Multi-speed selection Multi-speed can be selected according to the combination of RH, RM and RL signals.

Contact input common
(sink)
Common terminal for the contact input terminal (sink logic).
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.
24 VDC power supply
common Common terminal for the 24 VDC power supply (terminal PC).
Isolated from terminal 5.
PC
External transistor common
(sink)
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).
24 VDC power supply Can be used as a 24 VDC 30 mA power supply.

Frequency setting power
supply Used as the power supply for an external device such as a
frequency setting potentiometer or digital panel meter. 5 VDC (±0.2 VDC),
permissible load current: 10 mA
2 Frequency setting (voltage)
Inputting 0 to 5 VDC (or 0 to 10 VDC) provides the
maximum output frequency at 5 V (or 10 V) and makes
input and output proportional. Use
Pr.73 to switch
between input 0 to 5 VDC (initial setting) and 0 to 10 VDC.
Input resistance: 10 k Ω (±1 k Ω ),
Maximum permissible voltage: 20 VDC.
4 Frequency setting (current)
Inputting 4 to 20 mADC (or 0 to 5 V, 0 to 10 V) provides
the maximum output frequency at 20 mA and makes input
and output proportional. This input signal is valid only
when the AU signal is ON (terminal 2 input is invalid). Use
Pr.267 to switch among input 4 to 20 mA (initial setting), 0
to 5 VDC, and 0 to 10 VDC. Set the voltage/current input
switch in the "V" position to select voltage input (0 to 5 V /
0 to 10 V).
For voltage input,
input resistance: 10 k
Ω (±1 k Ω ),
maximum permissible voltage: 20 VDC.
For current input,
input resistance: 249
Ω (±5 Ω ),
permissible maximum current: 30 mA.
5 Frequency setting common
Common terminal for the frequency setting signal input
(via terminal 2 or 4). Do not earth (ground).
