be

done, the

same

as with the FR-PUO3. Note that the function assigned to the

@

key on the FR-ARW03 dif-

fers

from that on the FR-PUO3.

With the FR-ARW03

it

is possible to read

the

inverter parameters set for individual applications

collectively and to copy them to other inverters.

Note: 1.

Do

not copy the parameters between differing voltage classes or differing capacities.

If

the parameters are copied between differing voltage classes or differing capacities,

the motor rotation may become unstable, unexpected alarms may occur, or the

inverter‘s performance may

be

acheved. Contact Mitsubishi if the parameters are

copied by mistake.

2.

If

copying the parameters from old version to new version, the set value of Pr.31 and

Pr.81 changes. After parameter copy from old version to new version, manually set

“0”

to Pr.31 and set

‘9999”

WIRING

6.1

Precautions

When wiring, consider the following items to avoid erroneous operation, damage or incorrect

usage to the inverter.

Cautions on Wiring

(1)

Do

not connect the power supply wires to the output terminals

(U,

V,

W)

01

the inverter.

If

they are connected to these terminals,

it

will damage the inverter.

(2)

Terminals P and

PR

are used for connection

01

the optional brake resistor (refer to

page

131).

Never short circuit or connect anything other than the brake resistor across

these terminals.

(3)

Use sleeved

solderless

terminals for the connection

of

the power supply and the motor.

(4)

Common terminals

SD,

5,

and

SE

in

the terminal block for the control circuit are not

at the same potential.

Do

not connect or ground these terminals.

(5)

Use only shielded or twisted caMes to connect the control circuits. These wires must

be

routed as far as possible from the main power and AC relay logic circuits.

(6)

During wiring, close the

slots

on

the top of the inverter with a cover

so

that cut pieces

of

wire

will

not

enter

the

inverter.

(7)

If

modilkation

of

the

wiring

OT

other work becomes necessary aiter operating the in-

verter, do not touch the wire or terminals until power is disconnect and the POWER

CHARGE indicating lamp is extinguished for at least

two

minutes.

(8)

Any pekon who is involved in the wiring

of

this equipment should

be

fully competent

to carry out the work.

be reduced due to voltage drop in the motor cable, especially when the motor is

operating at low frequencies. Select the wire size

so

that voltage drop is

less

than

2%.

(2)

At extreme distances. the charging current generated due to floating capacity between

the wires may trigger the current limit function. To avoid this problem, the maximum

wiring distance should be limited

to

the values given in the following table. If the ap-

plication

requires wiring longer than the permissible lirnlts, refer to page

OPERATION

11.1

Operation

Modes

The operation mode

of

the inverter is classified into the following three modes

-

the external

operation mode in which the inverter operation is controlled by the external signals, the

PU

opera-

tion mode in which the inverter operation is controlled by the parameter unit, and the combined

operation mode in which the inverter operation is controlled by both

the

externals signals and the

parameter unit.

Factory-set operation

mode

When power is turned

ON

or

when the in-

verter is reset, the operation mode is set to

"operation using external input slgnals".

Therefore, the inverter can be operated using

the external signals when

it

is tumed

ON.

The

inverter starts operating if the start signal

(STF/STR and

SD)

is turned

ON

in this state.

A

speed reference signal is also required for

motor rotation.

To

fix the operation

mode

it is possible to set the operation mode which

is established when power is turned

ON.

For

example, if the inverter needs to

be

operated

only in the PU operation mode, it is possible

to set the PU operation mode as the mode to

be

estaMished when power is tumed

ON.

In

OPERATION

Note:

After turning

ON

the

MRS

terminal, if the setting for Pr.79

is

changed to any value other

than '7" in the PU operation mode, the

MRS

terminal functions as the ordinary

MRS

terminal (mechanical reset terminal) instead

of

the edit enable signal terminal. Then the

operation

mode

is changed according to the new setting for Pr.79.

When mode changed is attempted between the external operation mode to the PU

operation mode with the

MRS

terminal

ON,

the mode change will not occur

if

the STF

or STR terminal is

ON.

In the setting

of

Pr.79

=

7 with the

MRS

terminal

ON,

if the

MRS

terminal is turned OFF

while in the PU operation mode, the operation

mode

is changed to

the

external opera-

tion

mode

independent

of

the OWOFF status of the terminal (STF,

STR).

Therefore,

if

the

MRS

terminal

is

turned OFF while either the STF or STR terminal

IS

ON,

the motor

is controlled in the external operation mode.

During the operation in the PU operation mode, the ordinary

MRS

function does not

work.

When the mode is changed from the PU operation mode to the external operation

mode forcibly, the parameter unit is internally reset once

to

secure the monitor screen.

If an alarm has occurred, the inverter can be reset by pressing the stop key in the PU

operation mode. Resetting

of

the inverter in the external operation mode is not possible.

Therefore, resetting the inverter always changes the mode to the PU operation mode.

function:

(1)

If

the parameter unit is not connected at the start of operation, an alarm does not occur.

(2)

This function recognizes "disconnection" when the parameter unit is disconnected for more

(3)

To restart the inverter operation after the occurrence of the disconnection alarm, confirm the

connection of the parameter unit and reset the inverter. (refer

to

(4)

If the inverter is operated without selecting the parameter unit disconnection detection func-

tlon, inverter operation is continued even after the parameter unit is disconnected from the

inverter, which will create a hazardous situation. Therefore, to ensure safe operation, it

is

recommended

that

the parameter unit disconnection detection function

SELECTING GENERAL-PURPOSE MAGNETIC FLUX VECTOR CONTROL

The general-purpose magnetic flux vector control can be selected by setting the motor capacity

and

type

of motor.

The general-purpose magnetic flux vector control is effective for applications where greater start-

ing torque or more than

VF

mode

torque at low speed is required. or the load is varying.

(1) Conditions for selecting the general-purpose magnetic flux vector control

The general-purpose magnetic flux vector control can be effectively used only when the foi-

lowing conditions are satisfied. If

the

general-purpose magnetic flux vector control is selected

while any of these conditions is not satisfied, it will cause insufficient torque, irregular rotation,

and other problems. In which

case,

should

be

selected.

Conditions

INSPECTION AND MAINTENANCE

The general-purpose inverter is

static

equipment mainly consisting of semiconductor devices. To

prevent problems occurring due

to

environmental conditions such as high temperature, humidity,

dust, and vibration, or aging of the component parts, inspection at regular intervals is necessary.

23.1

Precautions on Inspection and Maintenance

After the power is turned

olf,

the smoothing capacitor remains charged at high voltage for a while.

Remove the front cover and wait until the POWER indicating lamp (refer

to

circuit board

goes

off.

Start inspection or maintenance several minutes affter

the

INSPECTION AND MAIN'TEMNCE

23.3

Replacing

Pam

The inverter consists of a number of electronic component

parts

such

as

semiconductor

devices.

Due

to their

physical

properties,

it

is anticipated that the following component

patts

will deteriorate

with time,

kadw

to troubles or hered performance of the inverter. They should

be

rephced

at regular Intervals for preventive maintenance.

(1)

Cooling fan

A cooling fan is used to cool heat generating parts such as semiconductor devices in the

main circuit. Although the service life

of

the bearing used in the cooling fan is, under normal

operating conditions,

20,000

hours, it will vary in the range of

10,OOO

to

35,000

hours

depending on ambient temperatures.

Therefore, if the system

is

continuously operated, it is necessary to replace the cooling fan

assembly every

two

to three years. Beside this regular replacement, if abnormal noise or

vibration is detecled during inspection, the cooling fan assembly should

be

replaced imme-

diately.

A

large capacity aluminum electrolytic capacitor for smoothing the current is

used

in me direct

current circuit

in

the main circuit.

The

performance of the capacitor

is

degraded due to the

influence of ripple, etc. Although the service life

of

the capacitor varies depending on the am-

bient temperatures and operating conditions, the capacitor should be replaced every five

years assuming that the parameter unit is used within specified environmental limits.

Since the deterioration of a capacitor accelerates over lime, it should be checked at least

once a year. As it approaches the end of service life, it should be checked every six months

or at shorter intenals. The inspection items and defects which require the capacitor to be

replaced are summarized below.

1)

Case conditions: Expansion

of

the case at the side and bottom

2)

Sealing conditions: Excessive curvature or cracks

3)

Safety valve conditions: Excessive expansion

of

the valve or an actuated valve

4)

Others:

(2)

Smoothing

wpncltor

Check for cracks, discoloration, leakage, or other defects. Measure the capacity.

If

measured capacity is less than

85%

of rated, the capacitor should

be

replaced.

(3)

Relays

Relay contacts deteriorate with use. Relays should be replaced according to the total number

of

makebreak operations (service life).

The following table shows the part replacement intervals. In addition to the parts given in this

table, lamps and other component parts having shorter service life should be inspected at

regular intervals.

There are two

types

of noises-external mises which cause malfunctioning

of

the inverter and

those radiated from the inverter to cause malfunctioning of a peripheral device. ARhough the in-

verters are designed not to

be

influenced by noises, the following general measures must be

taken siree the inverter is an electronic device which handles weak signals. In addition, since the

inverter chops the output by high carrier frequency, the inverter itsel is a source of noise genera-

tion. If peripheral equipment is affected by the noise generated by the inverter, noise suppressing

measures must also be taken. The noise suppressing measures differ depending on noise

propagation route.

To protect

it

is

necessary

to

install a fuse or

no-

fuse breaker (NFB).

The

NFB must

be

selected with regard to the power factor at the power

supply side of inveqer (will vary according to power supply voltage,

output

frequency, and

load). For selection, refer

to

the table above. Especially, when a NFB of electromagnetic type

is used, the operating characteristics vary due to high hamnic currents. This means that the

NFB which is one rank above the proper

size

must

be

selected.
