Terminal Name
Connect to the commercial power supply. Keep these terminals open when using the high
AC power input
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.
Inverter output
Connect a three-phase squirrel-cage motor.
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)
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/-.
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).
Turn ON the STF signal to start forward rotation and turn it OFF
to stop.
Turn ON the STR signal to start reverse rotation and turn it OFF
to stop.
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 inverter output.
Output stop
Use to shut off the inverter output when stopping the motor by electromagnetic brake.
Used to reset alarm output provided when protective circuit is activated. Turn ON the RES
Reset 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.
Common terminal for contact input terminal (sink logic) and terminal FM.
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.
Common output terminal for 24VDC 0.1A power supply (PC terminal).
common Isolated from terminals 5 and SE.
Connect this terminal to the power supply common terminal of a transistor output (open
common collector output) device, such as a programmable controller, in the sink logic to avoid
malfunction by undesirable current.
Common terminal for contact input terminal (source logic).
(source)
Can be used as 24VDC 0.1A power supply.
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 output
frequency at 5V (10V) and makes input and output
(voltage)
proportional. Use Pr. 73 to switch between input 0 to 5VDC
(initial setting) and 0 to 10VDC input.
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
(current)
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).
Common terminal for the frequency setting signals (terminals 2 and 4). Do not earth (ground).
