SAFETY PRECAUTIONS

:$51,1*

Always read these precautions

before using this equipment.

Before designing your system, make sure to read the related manuals of your

products to ensure that you exercise appropriate caution with regards to safety.

Take the following precautions and use the equipment correctly when practicing

and learning the material.

The Mitsubishi general-purpose inverter FR-E700 series is used for this training. If

the equipment in your actual environment is different, make sure to read the specif-

ic manual for your device as operation methods and parameter type differ depend-

ing on the specic model of inverter.

Training precautions

● Do not touch the terminals when the power is on to prevent electric shock.

● Before opening the cover, either turn off the power or ensure that it is safe to open the cover.

● Do not insert your hands into moving parts.

This section is specically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you have read through the Instruction Manual and appended documents carefully and can use the equipment correctly. Do not use this product until you have a full knowledge of the equipment, safety information and instructions. In this Instruction Manual, the safety instruction levels are

classied into "WARNING" and "CAUTION".

Incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.

The according to conditions. Both instruction levels must be followed

because these are important to personal safety.

level may even lead to a serious consequence

1. Electric shock prevention

● While power is ON or when the inverter is running, do not

open the front cover. Otherwise you may get an electric shock.

● Do not run the inverter with the front cover or wiring cover removed. Otherwise you may access the exposed high voltage

terminals or the charging part of the circuitry and get an electric shock.

● Even if power is OFF, do not remove the front cover except for wiring or periodic inspection. You may access the charged inverter circuits and get an electric shock.

● Before wiring or inspection, power must be switched OFF.

To conrm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in

wiring or inspection shall wait for at least 10 minutes after the

power supply has been switched OFF and check that there

are no residual voltage using a tester or the like. The capacitor

is charged with high voltage for some time after power OFF,

and it is dangerous.

● This inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety

regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.

● Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.

● The inverter must be installed before wiring. Otherwise you may get an electric shock or be injured.

● M Dial and key operations must be performed with dry hands to prevent an electric shock. Otherwise you may get an electric shock.

● Do not subject the cables to scratches, excessive stress,

heavy loads or pinching. Otherwise you may get an electric

shock.

● Do not change the cooling fan while power is ON.

It is dangerous to change the cooling fan while power is ON.

● Do not touch the printed circuit board with wet hands. Otherwise you may get an electric shock.

● When measuring the main circuit capacitor capacity, the DC voltage is applied to the motor for 1s at powering OFF. Never touch the motor terminal, etc. right after powering OFF to

prevent an electric shock.

2. Fire prevention

● Inverter must be installed on a nonammable wall without holes (so that nobody touches the inverter heatsink on the rear side,

etc.). Mounting it to or near ammable material can cause a re.

● If the inverter has become faulty, the inverter power must be switched OFF. A continuous ow of large current could cause a re.

● When using a brake resistor, a sequence that will turn OFF power when a fault signal is output must be congured. Otherwise the brake resistor may excessively overheat due to damage of the brake transistor and such, causing a re.

● Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing so could cause a re.

3. Injury prevention

● The voltage applied to each terminal must be the ones specied in the Instruction Manual. Otherwise burst, damage, etc. may occur.

● The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur.

● Polarity must be correct. Otherwise burst, damage, etc. may occur.

● While power is ON or for some time after power-OFF, do not touch the inverter as they will be extremely hot. Doing so can cause burns.

4. Additional instructions Also the following points must be noted to prevent an ac-

cidental failure, injury, electric shock, etc.

(1)

Transportation and mounting

● The product must be transported in correct method that cor- responds to the weight. Failure to do so may lead to injuries.

● Do not stack the boxes containing inverters higher than the number recommended.

● The product must be installed to the position where withstands the weight of the product according to the information in the Instruction Manual.

● Do not install or operate the inverter if it is damaged or has parts missing.

● When carrying the inverter, do not hold it by the front cover or M Dial; it may fall off or fail.

● Do not stand or rest heavy objects on the product.

● The inverter mounting orientation must be correct.

● Foreign conductive bodies must be prevented to enter the inverter. That includes screws and metal fragments or other

ammable substance such as oil.

● As the inverter is a precision instrument, do not drop or subject it to impact.

● The inverter must be used under the following environment.

Otherwise the inverter may be damaged.

(2) Wiring

&$87,21

:$51,1*

&$87,21

● Do not install a power factor correction capacitor or surge sup- pressor/capacitor type lter on the inverter output side. These

devices on the inverter output side may be overheated or burn out.

● The connection orientation of the output cables U, V, W to the motor affects the rotation direction of the motor.

(3) Trial run

● Before starting operation, each parameter must be conrmed and adjusted. A failure to do so may cause some machines to

make unexpected motions.

(4) Usage

● Any person must stay away from the equipment when the retry function is set as it will restart suddenly after trip.

● Since pressing the function setting status, separate circuit and switch that

make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.

● OFF status of the start signal must be conrmed before resetting the inverter fault. Resetting inverter alarm with the

start signal ON restarts the motor suddenly.

● The inverter must be used for three-phase induction motors. Connection of any other electrical equipment to the inverter

output may damage the equipment.

● Do not modify the equipment.

● Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the product.

key may not stop output depending on

● The inverter can be easily set for high-speed operation. Before changing its setting, the performances of the motor and machine must be fully examined.

● Stop status cannot be hold by the inverter's brake function. In addition to the inverter’s brake function, a holding device must be installed to ensure safety.

● Before running an inverter which had been stored for a long period, inspection and test operation must be performed.

● For prevention of damage due to static electricity, nearby metal must be touched before touching this product to eliminate static electricity from your body.

● If you are installing the inverter to drive a three-phase device while you are contracted for lighting and power service, consult your electric power supplier.

(5) Emergency stop

● A safety backup such as an emergency brake must be provid- ed to prevent hazardous condition to the machine and equipment in case of inverter failure.

● When the breaker on the inverter input side trips, the wiring

must be checked for fault (short circuit), and internal parts of the

inverter for a damage, etc. The cause of the trip must be identi-

ed and removed before turning ON the power of the breaker.

● When any protection function is activated, appropriate cor- rective action must be taken, and the inverter must be reset before resuming operation.

(6) Maintenance, inspection and parts replacement

● Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.

(7) Disposal

● The electronic thermal O/L relay function does not guarantee pro- tection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection.

● Do not use a magnetic contactor on the inverter input for

frequent starting/stopping of the inverter. Otherwise the life of

the inverter decreases.

● The effect of electromagnetic interference must be reduced

by using a noise lter or by other means. Otherwise nearby

electronic equipment may be affected.

● Appropriate measures must be taken to suppress harmonics.

Otherwise power supply harmonics from the inverter may heat/

damage the power factor correction capacitor and generator.

● When driving a 400V class motor by the inverter, the motor must be an insulation-enhanced motor or measures must be taken to suppress surge voltage. Surge voltage attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.

● When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations because all parameters return to the initial value.

● The inverter must be treated as industrial waste.

General instruction

Many of the diagrams and drawings in this Instruction Manual show

the inverter without a cover or partially open for explanation. Never

operate the inverter in this manner. The cover must be always reinstalled and the instruction in this Instruction Manual must be followed when operating the inverter.

Brief description of inverters

Inverter basics

As we will cover in more detail throughout this document, "inverters" are devices

used to control motor speed.

While this is not a term often heard in typical conversation, inverters are used in

many of the devices used on a daily basis.

Inverters are used in trains, for example. "Inverters" control the speed of motors in

trains to control the speed of the train itself to ensure safe operation.

This chapter describes the fundamentals of "inverters".

1-1

1.1 What is an inverter?

1.1.1 Basic functions of the inverter

◎Inverter

Motors are used to operate many of the devices and products we use on a daily basis. The reason devices do not suddenly start to operate when power switches are turned on is because the inverter controls the speed of motors.

In basic terms, the inverter is a device that changes the speed of standard motors without restriction.

1.1.2 Benets of the inverter

The inverter can freely changes the speed of standard motors. They can be

also connected to the already-installed standard motors.

3 4

The inverter can drive standard motors at a set speed regardless the power supply frequency.

The inverter can save energy (electricity).

The inverter can improve productivity by changing the standard motor speed to match the application.

The inverter can perform smooth start and stop operations by reducing the starting current of standard motors.

1-2

1.1.3 Familiar examples where inverters are used

Belt conveyors used in factories

☆Improve efciency of work, braking at specic positions, automatic operation

● The inverter improves efciency of work and enable conveyors to be stopped at specic positions.

● Conveyor speeds can be optimally adjusted depending on the work conditions.

● Soft starts and stops prevent products from moving around and falling off the conveyor.

● Conveyor acceleration and deceleration can be controlled such that shock to machines is reduced or removed completely.

1.2 Motor drive force

1.2.1 Motor and frequency

Motor speed is changed by varying the frequency of current owing through motors.

Frequency is discussed in more detail in this section.

◎Frequency

Outlets in homes, for example, supply power at 100V/50Hz and 200V/60Hz specications. "V" represents voltage and "Hz" represents the frequency. Frequency values are usually shown in a graph like this. For example, frequency 60Hz means that there are 60

waves between positive and negative per second.

1.2.2 Principles of the motor

When a motor is connected to a source of power, current ows through the stator winding, or stator coil, within the motor, which creates a rotating magnetic eld. This rotating magnetic eld causes the stator (rotor) to rotate.

Motor speed is proportional to the frequency of the power source. Basically, the motor rotates by electromagnetic force.

1.3 Changing frequency

1.3.1 Structure of the inverter

The inverter is generally comprised of 3 sections: converter section, inverter section, and control circuit.

◎Converter section

The converter section converts an AC of an AC power supply into a DC, and then smooths out the pulses of current by the smoothing capacitor.

◎Inverter section

The inverter section converts the DC converted by the converter section into a pulsed current of alternating current having variable frequency.

* Pulsed current refers to current that ows intermittently for short periods of time.

◎Control circuit

The control circuit controls the converter and inverter sections.

Arrangement of multiple inverters

Arrangement of the ventilation fan and inverter

Heat is blown up from inside the inverter by the small fan built in the unit.

Any equipment placed above the inverter should be heat resistant.

Arrangement of multiple inverters

When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown below in the gure (a). When it is inevitable to arrange them vertically to minimize space, take such measures as to provide guides

since heat from the bottom inverters can increase the temperatures in the top inverters, causing inverter failures.

When mounting multiple inverters, fully take caution not to make the surrounding air temperature of the inverter

higher than the permissible value by providing ventilation and increasing the panel size.

2.4.2 Troubleshooting

When a fault occurs in the inverter, the inverter trips and the PU display automatically changes to one of the following fault or alarm indications.

◎Retention of fault output signal

When the magnetic contactor (MC) provided on the input side of the inverter is opened when a fault occurs, the inverter's control power will be lost and the fault output will not be held.

◎Fault or alarm indication

When a fault or alarm occurs, the operation panel display automatically switches to the fault or alarm indication.

◎Resetting method

When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the inverter cannot restart.

When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation. Not doing so may lead to the inverter fault and damage.

Inverter fault or alarm indications are roughly categorized as below.

Error message

A message regarding operational fault and setting fault by the operation panel and parameter unit

(FR-PU04 /FR-PU07) is displayed. The inverter does not trip.

Warning

The inverter does not trip even when a warning is displayed. However, failure to take appropriate

measures will lead to a major fault.

Minor failure

The inverter does not trip. You can also output a minor failure signal by making parameter setting.

Major fault

Refer to Appendix 2 as it contains a list of fault displays and the appropriate troubleshooting steps to resolve the issue.

When a fault occurs, the inverter trips and a fault signal is output.

Parameters

Inverter basics

You must have an understanding of parameters in order to congure "inverters".

We will use the belt conveyor example described in Chapter 1 again here. If the motor

moving the belt conveyor is not rotated smoothly, items on the belt conveyor could

fall off and break. The motor must be started slowly to ensure that the conveyor

moves smoothly.

The motor can be rotated smoothly in such a manner by conguring inverter parameters.

This chapter will introduce typically used parameters.

This chapter describes external connections that make using inverters even easier

to use.

5.1 Connecting GOT with the inverter

This document describes the procedure to establish a peer-to-peer connection with Mitsubishi general-purpose

inverter FR-E700 series and Mitsubishi GOT2000 series GT2708. Refer to specic manuals for information on connecting other inverters and GOTs.

5.1.1 Function overview

GOT is an acronym for Graphic Operation Terminal.

Hardware switches and lamps installed to a conventional control panel have been replicated in software and combined with a touch panel display device to enable viewing of information and device operation via the

monitor screen. The GOT can connect and send commands to up to 31 inverters via RS-485 communication. The GOT is equipped with USB ports located in the front so that doors do not have to be opened when performing inverter maintenance. The USB port on the GOT can be used to connect inverters without USB ports to PCs and use FR Congurator. Parameter conguration backups to SD cards can be performed with GOT2000

or later devices, which enables you to replace your Mitsubishi general-purpose inverter of the same type and

restore the conguration saved on the SD card to the new inverter. This backup and restore functionality also signicantly reduces time to load data into devices and equipment used for mass production.
