WIRING

• Precautions for wiring

Pay attention to the

following

items

during

wiring

to prevent mistaken

wiring

and mistaken usages.

,------------

Precautions

for

wirlng-------------..

(1)

When the power supply is applied on the inverter

output

terminals

CU,

Vand

W), the inverter will be damaged. Never wire the power

supply

to these

terminals.

(2)

Use a shield or twisted wire for the wiring to the control circuit

terminal,

and separate the

wires

from

the

main

circuit

or power

distribution

circuit

(200V

relay

sequence

circuit, etc.).

(3)

Cover

the

slits

on the inverter so

that

the

wire

waste

does

not

enter

the

inverter

during

wiring.

(4)

Confirm

that

the

display

lamp

on the key pad has gone out before changing

the

wiring

after

operation,

and

wait

at

least

two

minutes

before

starting

the

wiring.

(It

takes

more

than

one

minutes

for

discharge

of

the

internal

capacitors

after

disconnecting

loop

Details to be checked in wiring planning

(1) When

the

circuit has current loop in the power supply

due to a mistaken connection as well as to a commercial

selector circuit as shown on the right, the inverter will

be damaged. Always create an electrical and mechanical
interlock

for

MCl and MC2.

(2) If a power failure occurs and the

start signal

(start

switch)
is retained. the inverter will automatically resume operation when the power is restored.
If the machine must be prevented from restarting with power restoration, install a magnetic

ccntector

MC on the primary side of the inverter, and design a sequence to prevent the

start

signal from turning ON.

(3) Use

two

contacts

in parallel or a twin contact to prevent an imperfect

contact

for the input

signal of the control circuit.

(4) Do not input a voltage on the

contact

input terminal (STF, etc.) of the control circuit.

(5) Do not apply the voltage directly

onto

the alarm

output

signal terminal

(8,

C). Pass the

voltage

through

a relay coil or ramp.

(6) When directly connecting the open collector

output

such as

that

from a sequence controller

into the inverter input terminal. make sure

that

a backflow current does not occur.

-15-

Countermeasures
(1)

Insert a diode to prevent

the backflow current.

(2) Use an

all-point

isolated

type output unit.

(Ex.

AY40A,

etc.)

(3) The external power supply

voltage must be
higher than the inverter's
control power supply.

(1)

When setting the PWM

carrier

Ireq uenoy

(Pr

.72) to 7.1kHz or

more

to lower the

motor

acoustic

noise, the rated

output

should

be derated as

shown

on the right.

Also change the electronic

thermal

relay

(Pr.

(2)

If the PWM

carrier

frequency

is increased, the

acoustic

noise from the

motor

will
lower, but the noise qenerated
by the inverter

and

the leakage

current

will increase.

2. Noise
Thereisnoise

that

enters

from

outside

and

causes

the inverter to

malfunction

and

that

which is

generated

from

the

inverter

and

causes

the

peripheral

equipment

to

malfunction.

The inverter is

designed

so

that

it is not

easily

affected by noise.

but

as it is

an

electronic

device which

handles

weak

signals.

the

following

general

countermeasures

will be

required.

+General

countermeasures

• Avoid

laying

the

inverter's

power

cables

(input/output)

in

parallel

with

the

signal

wires

and

avoid

bundling

the

power

cables

and

signal

wires.

• Use

twisted

pair

shield

wires

for

the

connection

wires

with

the

sensor

and

for

the

control

signal

wires.

Connect the

sheath

of the

shield

wire

to

terminal

SO.

• Use

one-point

grounding

for

the inverter

and

motor.

etc.

+Example

of noise

countermeasures

Motor

Use a s-ecre cable for the
motor power cable, and use
one wire for the grounding.

Install a filter (FR·BSFOl)

Do not ground the shield,

3. Leakage

current

Leakage

current

will

flow

through

stray

capacity

which

exists

between the

ground

and

a cable,

motor,

etc. The

value

of the

leakage

current

depends

on the

cable

length,

wiring

method

and

inverter

carrier

frequency, and will

increase

when

using

a

low-acoustic

noise inverter, so use the

following

countermeasures.

(1)

Leakage

current

to the

ground

The

leakage

current

will not

affect

only

the

inverter

but

may

pass

into

other

equtpments

through

the

grounding

cables

and

may

cause

a

leakage

breaker

or

relay

unnecessary

trip.

_Countermeasures

Route

of

leakage

current

•

Lower

the

inverter's

carrier

frequency

(Pr.

72). Note

that

this

will

increase

the

motor

acoustic

noise

.

• Use a

leakage

breaker

that

corresponds

to high

harmonics

and

surges

(Mitsubishi

New

Super

NV Series,

etc.)

for the inverter

or

other

lines

when

using

the

low-acoustic

noise model

(with

high

carrier

frequency).

-43-

(2)

Leakage

current

across

the line

The

harmonics

of leakage

current

which flows

through

stray

capacity

across

the

inverter output lines

may

cause an external

thermal

overload protector trip.

When the cable length is long (50m or more), the

ratio

of leakage

current

to the

motor's

rated

current

becomes large.

and

trip

is liable to occur.

• Countermeasures

• Use the electronic

thermal

relay on the inverter.

• Lower the

carrier

frequency.

Note

that

this will increase

the

motor

noise.
