Symbol Terminal Name Description

Input signals

Frequency

setting input

common

Common terminal for the frequency setting signals

(terminals 2, 4) and indicator connection (terminal AM).

Isolated from terminals SD and SE. Do not connect this

terminal to the ground.

Alarm output

1 contact output which indicates that the

protective function of the inverter is

activated to stop output. 230V 0.3A AC,

30V 0.3A DC. No conduction across B-C

(conduction across A-C) when alarm

(error) state.

Conduction across B-C (no conduction

across A-C) when normal. (*6)

Open collector

RUN Inverter running

Low when the inverter output frequency

is the starting frequency or higher

(factory-set to 0.5Hz and changeable),

and High during stop or DC injection

brake operation (*2). Permissible load

24V 0.1A DC

The terminal

function

changes with the

setting of output

terminal function

selection

(Pr. 64, Pr. 65).

(*5)

Open collector

common

Common terminal for inverter running terminal RUN.

Isolated from terminals 5 and SD.

Pulse

For meter

Factory setting of output item:

Frequency

Permissible load current 1mA

1440 pulses/s at 60Hz

Output signals

Indicator

Analog

<NA, EC>

Analog signal

output

One selected from output

frequency and motor

current is output.

The output signal is

proportional to the

magnitude of each

monitoring item.

Factory setting of output item:

Frequency

Output signal 0 to 5VDC

Permissible load current 1mA

Communication



RS-485

connector

(*3)

Using the parameter unit connection cable (FR-CB201 to

205), the parameter unit (FR-PU04) can be connected.

Communication operation can be performed using RS-485.

*1. Do not connect terminals SD and PC each other or to the ground.

For sink logic, terminal SD acts as the common terminal of contact input. For source

logic, terminal PC acts as the common terminal of contact input.

*2. Low indicates that the open collector output transistor is on (conducts). High indicates

that the transistor is off (does not conduct).

*3. Compatible with only the type having the RS-485 communication function. For details,

refer to the separately available instruction manual (detailed).

*4. RL, RM, RH, RT, AU, STOP, MRS, OH, REX, JOG, RES, X14, X16, (STR) signal

selection

*5. RUN, SU, OL, FU, RY, Y12, Y13, FDN, FUP, RL, LF, ABC signal selection

*6. For compatibility with the European Directive (Low Voltage Directive), the operating

capacity of relay output (A, B, C) should be 30V, 0.3A DC.
