Note
Set Pr. 267 and a voltage/current input switch correctly, then input an analog signal in accordance with the setting. Applying
a voltage with voltage/current input switch in "I" position (current input is selected) or a current with switch in "V" position
(voltage input is selected) could cause component damage of the inverter or analog circuit of output devices.
The inverter will be damaged if power is applied to the inverter output terminals (U, V, W). Never perform such wiring.
indicates that terminal functions can be selected using Pr. 178 to Pr. 182, Pr. 190, Pr. 192 (I/O terminal function selection).
Terminal names and terminal functions are those of the factory set.
Connect to the commercial power supply. Keep these terminals open when using the high 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.
Connect a three-phase squirrel-cage motor.
Connect a brake resistor (FR-ABR, MRS type, MYS type) across terminals P/+ and PR.
(The brake resistor can not be connected to the 0.1K and 0.2K.)
Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV) or high power
factor converter (FR-HC).
Remove the jumper across terminals P/+-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.
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. When the STF and STR signals
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.
Common terminal for contact input terminal (sink logic) and terminal FM.
When connecting the transistor output (open collector output), such as a programmable controller,
when source logic is selected, connect the external power supply common for transistor output to this
(source)
terminal to prevent a malfunction caused by undesirable currents.
Common output terminal for 24VDC 0.1A power supply (PC terminal).
Isolated from terminals 5 and SE.
When connecting the transistor output (open collector output), such as a programmable controller,
when sink logic is selected, connect the external power supply common for transistor output to this
terminal to prevent a malfunction caused by undesirable currents.
Can be used as 24VDC 0.1A power supply.
Used as power supply when connecting potentiometer for frequency setting
supply (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 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 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 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).
Common terminal for the frequency setting signals (terminals 2 or 4). Do not earth (ground).
For connecting PTC thermistor output.
When PTC thermistor protection is valid (Pr. 561 ≠ "9999"), terminal
2 is not available for frequency setting.
1 changeover contact output indicates that the inverter fault occurs.
Fault: discontinuity across B-C (continuity across A-C), Normal: continuity across B-C (discontinuity
across A-C) Contact capacity 230VAC 0.3A (power factor = 0.4) 30VDC 0.3A
Switched low when the inverter output frequency is equal to or
higher than the starting frequency (initial value 0.5Hz). Switched
high during stop or DC injection brake operation.
(Low is when the open collector output transistor is ON (conducts).
High is when the transistor is OFF (does not conduct).)
Select one e.g. output frequency from monitor items. (Not output
For meter during inverter reset.) The output signal is proportional to the
magnitude of the corresponding monitoring item.
With the PU connector, RS-485 communication can be made.
· Conforming standard: EIA-485 (RS-485)
PU connector · Transmission format: Multi-drop link
· Communication speed: 4800 to 38400bps
· Overall extension: 500m
S1/S2 are safe stop signals for use with in conjunction with an approved external safety unit. Both S1/
S2 must be used in dual channel form. Inverter output is shutoff depending on shorting/opening
between S1 and SC, S2 and SC.
Remove the shorting wire before using between S1, S2 and SC terminals.
This is a status signal for the safety related input signals.
Low indicates 'safe state' and high is 'drive enable or fault detected'. If high is indicated when both S1 and S2 are
open, refer to Safety stop function instruction manual (BCN-A211508-000) for diagnostics and repair action.
(Low is when the open collector output transistor is ON (conducts). High is when the transistor is OFF
(does not conduct).)
