Terminal Name
Connect to the commercial power supply. Keep these terminals open when using the high power
AC power input
factor converter (FR-HC2) or power regeneration common converter (FR-CV).
Drive unit output
Connect a PM motor.
Brake resistor
Connect a brake resistor (MRS type, FR-ABR) across terminals P/+ and PR.
(The brake resistor can not be connected to the 0.1K or 0.2K)
connection
Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV) or high power
Brake unit connection
factor converter (FR-HC2).
DC power input
Connect the plus side of the power supply to terminal P/+ and minus side to terminal N/-.
DC reactor connection
Remove the jumper across terminals P/+ and P1 and connect a DC reactor
Earth (Ground)
For earthing (grounding) the drive unit chassis. Must be earthed (grounded).
Turn ON the STF signal to start forward rotation and turn it OFF to
Forward rotation start
stop.
Turn ON the STR signal to start reverse rotation and turn it OFF to
Reverse rotation start
stop.
Multi-speed selection
Multi-speed can be selected according to the combination of RH, RM and RL signals.
Turn ON the MRS signal (20ms or more) to stop the drive unit output.
Output stop
Use to shut off the drive unit output when stopping the motor by electromagnetic brake.
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.
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 collector
External transistor
output) device, such as a programmable controller, in the source logic to avoid malfunction by
common (source)
undesirable current.
24VDC power supply
Common output terminal for 24VDC 0.1A power supply (PC terminal). Isolated from terminals 5 and
SE.
common
External transistor
Connect this terminal to the power supply common terminal of a transistor output (open collector

(sink) (initial setting)
Contact input common
Common terminal for contact input terminal (source logic).
(source)
24VDC power supply
Can be used as 24VDC 0.1A power supply.
Speed setting power
Used as power supply when connecting potentiometer for speed
supply
setting from outside of the drive unit.
Inputting 0 to 5VDC (or 0 to 10V) provides the maximum rotation
speed at 5V (10V) and makes input and output proportional. Use
Speed setting (voltage)
Pr.73 to switch between input 0 to 5VDC (initial setting) and 0 to
10VDC input.
Inputting 4 to 20mADC (or 0 to 5V / 0 to 10V) provides the
maximum rotation speed 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
Speed setting (current)
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).
Speed setting common
Common terminal for the speed setting signals (terminals 2 and 4). Do not earth (ground).
