(2) Wiring

CAUTION

z Do not fit capacitive equipment such as power factor correction capacitor, radio

noise filter (option FR-BIF(-H)) or surge suppressor to the output of the inverter.

z The connection orientation of the output cables U, V, W to the motor will affect the

direction of rotation of the motor.

(3) Trial run

CAUTION

z Check all parameters, and ensure that the machine will not be damaged by a

sudden start-up.

z When the load GD

output current may vary when the output frequency is in the 20Hz to 30Hz range. If this is a problem, set the Pr.72 "PWM frequency selection" to 6kHz or higher. (When setting the PWM to a higher frequency, check for noise or leakage current problem and take countermeasures against it.)

(4) Operation

is small (at the motor GD or smaller) for 400V from 1.5K to 3.7K, the

WARNING

z When you have chosen the retry function, stay away from the equipment as it will

restart suddenly after an alarm stop.

z Since the [STOP] key is valid only when functions are set (refer to page 55),

provide a circuit and switch to make an emergency stop (power off, mechanical brake operation for emergency stop, etc) separately.

z Make sure that the start signal is off before resetting the inverter alarm. A failure to

do so may restart the motor suddenly.

z The load used should be a three-phase induction motor only. Connection of any

other electrical equipment to the inverter output may damage the equipment.

z Do not modify the equipment. z Do not perform parts removal which is not instructed in this manual. Doing so may

lead to fault or damage of the inverter.

A-3

CAUTION

z The electronic thermal relay function does not guarantee protection of the motor

from overheating.

z Do not use a magnetic contactor on the inverter input for frequent starting/stopping

of the inverter.

z Use a noise filter to reduce the effect of electromagnetic interference. Otherwise

nearby electronic equipment may be affected.

z Take measures to suppress harmonics. Otherwise power supply harmonics from

the inverter may heat/damage the power capacitor and generator.

z When a 400V class motor is inverter-driven, please use an insulation-enhanced

motor or measures taken to suppress surge voltages. Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.

z When parameter clear or all clear is performed, reset the required parameters

before starting operations. Each parameter returns to the factory setting.

z The inverter can be easily set for high-speed operation. Before changing its

setting, fully examine the performances of the motor and machine.

z In addition to the inverter's holding function, install a holding device to ensure safety. z Before running an inverter which had been stored for a long period, always

perform inspection and test operation.

(5) Emergency stop

CAUTION

z Provide a safety backup such as an emergency brake which will prevent the

machine and equipment from hazardous conditions if the inverter fails.

z When the breaker on the inverter primary side trips, check for the wiring fault (short

circuit), damage to internal parts of the inverter, etc. Identify the cause of the trip, then remove the cause and power on the breaker.

z When any protective function is activated, take the appropriate corrective action,

then reset the inverter, and resume operation.

(6) Maintenance, inspection and parts replacement

CAUTION

z Do not carry out a megger (insulation resistance) test on the control circuit of the

inverter.

(7) Disposing of the inverter

CAUTION

z Treat as industrial waste.

Use the optional FR-CB2 . When the parameter unit (FR-PU04) is used, operation from the operation panel is not accepted. ( is valid)

(2) RS-485 communication

Using the RS-485 connector, you can perform communication operation from a personal computer etc. By connecting the RS-485 connector to computers such as personal computer and FA with a communication cable, you can run/monitor the inverter and read/write parameter values using a user program. For further details, refer to the instruction manual (detailed).

CAUTION

Do not plug the connector to a computer LAN board, fax modem socket, telephone modular connector etc. As they are different in electrical specifications, the inverter may be damaged.

Control circuit

3.3.4 Changing the control logic

The input signals are set to sink logic. To change the control logic, the jumper connector under the setting dial must be moved to the other position.

Change the jumper connector position using tweezers, a pair of long-nose pliers etc. Change the jumper connector position before switching power on.

CAUTION

•Make sure that the front cover is installed securely.

•The front cover is fitted with the capacity plate and the inverter unit with the

rating plate. Since these plates have the same serial numbers, always replace the removed cover onto the original inverter.

•The sink-source logic change-over jumper connector must be fitted in only one of those positions. If it is fitted in both positions at the same time, the inverter may be damaged.

3.3.5 Power-off and magnetic contactor (MC)

(1) Inverter input side magnetic contactor (MC)

On the inverter's input side, it is recommended to provide an MC for the following purposes. (Refer to page 3 for selection)

1) To release the inverter from the power supply when the inverter protective function is activated or the drive becomes faulty (e.g. emergency stop operation)

2) To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure

3) To rest the inverter for an extended period of time The control power supply for inverter is always running and consumes a little power. When stopping the inverter for an extended period of time, powering off the inverter will save power slightly.

4) To separate the inverter from the power supply to ensure safe maintenance and inspection work The inverter's input side MC is used for the above purpose, select class JEM1038AC3 for the inverter input side current when making an emergency stop during normal operation.

REMARKS

The MC may be switched on/off to start/stop the inverter. However, since repeated inrush currents at power on will shorten the life of the converter circuit (switching life is about 100,000 times), frequent starts and stops must be avoided. Turn on/off the inverter start controlling terminals (STF, STR) to run/stop the inverter.

As shown on the right, always use the start signal (ON or OFF across terminals STF or STR-SD) to make a start or stop.

*1. When the power supply

is 400V class, install a step-down transformer.

(2) Handling of output side magnetic contactor

In principle, do not provide a magnetic contactor between the inverter and motor and switch it from off to on during operation. If it is switched on during inverter operation, a large inrush current may flow, stopping the inverter due to overcurrent shut-off. When an MC is provided for switching to the commercial power supply, for example, switch it on/off after the inverter and motor have stopped.

Stall prevention is a function designed to suspend a frequency increase during acceleration, decrease frequency during constant speed or suspend a frequency decrease during deceleration if the preset current (0 to

200%) is exceeded, in order to

prevent an overcurrent alarm. Pr. 21 allows you to select whether to use stall prevention or not according to the acceleration/deceleration status. Since the high response current limit value

170%, torque will not be developed if Pr.

170%.

In that case, set "1" in Pr. 21. Used to reduce the stall prevention level at

ERRORS AND PROTECTIVE FUNCTIONS

Precautions for maintenance and inspection

7.7 Precautions for maintenance and inspection

The inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent any fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors.

7.7.1 Precautions for maintenance and inspection

For some short time after the power is switched off, a high voltage remains in the smoothing capacitor. When accessing the inverter for inspection, wait for at least 10 minutes after the power supply has been switched off, and then make sure that the voltage across the main circuit terminals P-N of the inverter is not more than 30VDC using a tester, etc.

7.7.2 Inspection item

(1) Daily inspection

•Basically, check for the following faults during operation.

1)Motor operation fault

7.7.5 Replacement of parts

The inverter consists of many electronic parts such as semiconductor devices. The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced performance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically.

Part Name

Cooling fan 2 to 3 years Replace (as required)

Main circuit smoothing

capacitor

On-board smoothing

capacitor

Relays — Replace as required

10 years * Replace the board (as required)

Description

* The design life of electrolytic capacitor is about ten years (36000h) if used for 10

hours a day and 365 days a year in the average yearly ambient temperature of 40°C (104°F).

CAUTION

For parts replacement, consult the nearest Mitsubishi FA Center.

ERRORS AND PROTECTIVE FUNCTIONS

Precautions for maintenance and inspection

(1) Cooling fan

The cooling fan is used to cool heat-generating parts such as the main circuit semiconductors. The life of the cooling fan bearing is usually 10,000 to 35,000 hours. Hence, the cooling fan must be replaced every 2 to 3 years if the inverter is run continuously. When unusual noise and/or vibration is noticed during inspection, the cooling fan must be replaced immediately.

Inverter Type Fan Type

FR-S520E-1.5K, 2.2K, 3.7K-NA MMF-06D24DS BKO-C2461H07 FR-S540E-1.5K, 2.2K, 3.7K-NA MMF-06D24ES-FC4 BKO-CA1027H09

zRemoval

1) Remove the front cover and wiring cover. (Refer to page 1.)

2) Unplug the fan connectors. The cooling fan is connected to the cooling fan connector beside the main circuit terminal block of the inverter. Unplug the connector and separate the inverter from the cooling fan.

3) Remove the cooling fan cover. Disengage the fixing hooks pointed by arrows to remove the cooling fan cover.

4) Remove the cooling fan and cooling fan cover. The cooling fan is secured by the fixing hooks. Disengage the fixing hooks to remove the cooling fan and cooling fan cover.

AIR FLOW

zReinstallation

1) After confirming the orientation of the fan, reinstall the fan so that the arrow on the left of "AIR FLOW" faces up.

CAUTION

Installing the fan in the opposite air flow direction can cause the inverter life to be shorter.

2) Reinstall the fan cover to the inverter. Run the cable through the wiring groove to prevent it from being caught between the chassis and cover.

3) Reconnect the cable to the connector. (Refer to "Removal" for the position of the connector.)

4) Reinstall the wiring cover.

Precautions for maintenance and inspection

(2) Smoothing capacitors

A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics are deteriorated by the adverse effects of ripple currents, etc. The replacement intervals greatly vary with the ambient temperature and operating conditions. When the inverter is operated in airconditioned, normal environment conditions, replace the capacitors about every 10 years. When a certain period of time has elapsed, the capacitors will deteriorate more rapidly. Check the capacitors at least every year (less than six months if the life will be expired soon). The appearance criteria for inspection are as follows:

1) Case: Check the side and bottom faces for expansion

2) Sealing plate: Check for remarkable warp and extreme crack.

3) Check for external crack, discoloration, fluid leakage, etc. Judge that the capacitor has reached its life when the measured capacitance of the capacitor reduced below 85% of the rating.

(3) Relays

To prevent a contact fault, etc., relays must be replaced according to the cumulative number of switching times (switching life).

impedances (including those of the input reactor and cables). *6. For single-phase 100V power input, the application of motor load reduces the output

voltage about 10 to 15%. Therefore, the load must be reduced when a general-purpose

motor is used.

other protection may be activated at power restoration. (in the external operation mode) *2. The braking torque indicated is a short-duration average torque (which varies with motor

loss) when the motor alone is decelerated from 60Hz in the shortest time and is not a

continuous regenerative torque. When the motor is decelerated from the frequency higher

than the base frequency, the average deceleration torque will reduce. Since the inverter

does not contain a brake resistor, use an optional brake unit (BU) when regenerative energy

is large. *3. Compatible with only the product having the built-in cooling fan. *4. Available for the FR-S520E-0.4K to 3.7K-NA only. *5.

Appendix 1 Instructions for compliance with the

European Directive

(The products conforming to the Low Voltage Directive carry the CE mark.)

(1) EMC Directive

1)Our view of transistorized inverters for the EMC Directive A transistorized inverter is a component designed for installation in an enclosure and for use with the other equipment to control the equipment/device. Therefore, we understand that the EMC Directive does not apply directly to transistorized inverters. For this reason, we do not place the CE mark on the transistorized inverters. (The CE mark is placed on inverters in accordance with the Low Voltage Directive.) The European power drive manufacturers' organization (CEMEP) also holds this point of view.

2)Compliance

We understand that the transistorized inverters are not covered directly by the EMC Directive. However, the EMC Directive applies to machines/equipment into which transistorized inverters have been incorporated, and these machines and equipment must carry the CE marks. Hence, we prepared the European Standardcompliant noise filters and the technical information "EMC Installation Guidelines" (information number BCN-A21041-202) so that machines and equipment incorporating transistorized inverters may conform to the EMC Directive more easily.

3)Outline of installation method Install an inverter using the following methods:

* Use the inverter with an European Standard-compliant noise filter. * For wiring between the inverter and motor, use shielded cables or run them in a

metal piping and ground the cables on the inverter and motor sides with the

shortest possible distance. * Insert a line noise filter and ferrite core into the power and control lines as required. Full information including the European Standard-compliant noise filter specifications are written in the technical information "EMC Installation Guidelines" (BCN-A21041-202). Please contact your sales representative.

(2) Low Voltage Directive

1) Our view of transistorized inverters for the Low Voltage Directive Transistorized inverters are covered by the Low Voltage Directive (Standard to conform to: EN50178).

2) Compliance We have self-confirmed our inverters as products compliant to the Low Voltage Directive and place the CE mark on the inverters.

3) Outline of instructions

* For the 400V class inverter, the rated input voltage range is three phase 380V to

415V 50Hz/60Hz.

* Do not use an earth leakage circuit breaker as an electric shock protector without

connecting the equipment to the earth. Connect the equipment to the earth securely.

* Wire the earth terminal independently. (Do not connect two or more cables to one

terminal.)

* Use the cable sizes on page 10 under the following conditions.

·Ambient temperature: 40°C (104°F) maximum

·Wire installation: On wall without ducts or conduits

If conditions are different from above, select appropriate wire according to EN60204 ANNEX C TABLE 5.

* Use the no-fuse breaker and magnetic contactor which conform to the EN or IEC

Standard.

* Use the breaker of type B (breaker which can detect both AC and DC). If not,

provide double or enhanced insulation between the inverter and other equipment, or put a transformer between the main power supply and inverter.

* Use the inverter under the conditions of overvoltage category II and contamination

level 2 or higher specified in IEC664.

* On the input and output of the inverter, use cables of the type and size set forth in

EN60204 Appendix C.

* The operating capacity of the relay outputs (terminal symbols A, B, C) should be

30VDC, 0.3A. * Control circuit terminals on page 11 are safely isolated from the main circuit. * Environment

Appendix 2 Instructions for UL and cUL

(Standard to comply with: UL 508C, CSA C22.2 No.14)

1. Installation

The S500E is UL-listed as a product for use in an enclosure. Design the enclosure so that the ambient temperature, humidity and ambience of the inverter will satisfy the above specifications. (Refer to page 80)

Branch circuit protection

For installation in the United States, branch circuit protection must be provided in accordance with the National Electrical Code and any applicable local codes. For installation in Canada, branch circuit protection must be provided in accordance with the Canada Electrical Code and any applicable provincial codes.

2. Wiring of the power supply and motor

For wiring the input (R, S, T) and output (U, V, W) terminals of the inverter, use the UL-listed copper wires (rated at 75 crimping terminals with the crimping tool recommended by the terminal maker.

°C) and round crimping terminals. Crimp the

3. Short circuit ratings

Suitable For Use in A Circuit Capable Of Delivering Not More Than 100kA rms Symmetrical Amperes.

4. Motor overload protection

These inverters provide solid state motor overload protection. Set Pr. 9 using the following instructions, (Pr. 9 "electronic thermal O/L relay").

•Set the rated current [A] of the motor in Pr. 9.

•Setting "0" in Pr. 9 disables electronic thermal relay function (motor protective func-

tion). (The protective function of the inverter is activated.)

•When using a Mitsubishi constant-torque motor, first set "1" in Pr. 71 "applied motor".

(This provides a 100% continuous torque characteristic in the low-speed range.) Then, set the rated current of the motor in Pr. 9 "electronic thermal O/L relay".

CAUTION

When two or more motors are connected to the inverter, they cannot be protected by

•

the electronic thermal relay function. Install an external thermal relay to each motor.

•When a difference between the inverter and motor capacities is large and the setting

becomes less than half amount of the inverter rated current, the protective characteristics of the electronic thermal relay function will be deteriorated. In this case, use an external thermal relay.

•A special motor cannot be protected by the electronic thermal relay function.

Use an external thermal relay.
