Thank you for choosing this Mitsubishi Transistorized inverter. This instruction manual (detailed) provides instructions for advanced use of the FR-S500 series inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this instruction manual and the instruction manual (basic) [IB-0600026] packed with the product carefully to use the equipment to its optimum. This instruction manual uses the International System of Units (SI). The measuring units in the yard and pound system are indicated in parentheses as reference values.

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you have read through the instruction manual (basic) and appended documents carefully and can use the equipment correctly. Do not use the inverter until you have a full knowledge of the equipment, safety information and instructions. In this instruction manual, the safety instruction levels are classified into "WARNING" and "CAUTION".

WARNING

CAUTION

Note that even the CAUTION level may lead to a serious consequence according to conditions. Please follow the instructions of both levels because they are important to personnel safety.

1. Electric Shock Prevention

While power is on or when the inverter is running, do not open the front cover. You may get an electric shock. Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock. 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 starting wiring or inspection, check for residual voltages with a meter etc. more than 10 minutes after power-off. Earth the inverter. Any person who is involved in wiring or inspection of this equipment should be fully competent to do the work. Always install the inverter before wiring. Otherwise, you may get an electric shock or be injured. Perform setting dial and key operations with dry hands to prevent 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. When you have removed the front cover, do not touch the connector above the 3-digit monitor LED display. You will get an electric shock.

Assumes that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Assumes that incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause physical damage only.

WARNING

A-1

2. Fire Prevention

CAUTION

Mount the inverter to incombustible material. Mounting it to or near combustible material can cause a fire. If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire. Do not connect a resistor directly to the DC terminals P(+), N(−). This could cause a fire.

3. Injury Prevention

Apply only the voltage specified in the instruction manual to each terminal to prevent damage etc. Ensure that the cables are connected to the correct terminals. Otherwise, damage etc. may occur. Always make sure that polarity is correct to prevent damage etc. While power is on and for some time after power-off, do not touch the inverter or brake resistor as they are hot and you may get burnt.

4. Additional instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc. (1) Transportation and installation

When carrying products, use correct lifting gear to prevent injury. Do not stack the inverter boxes higher than the number recommended. Ensure that installation position and material can withstand the weight of the inverter. Install according to the information in the Instruction Manual. Do not operate if the inverter is damaged or has parts missing. When carrying the inverter, do not hold it by the front cover or setting dia l; it may fall off or fail. Do not stand or rest heavy objects on the inverter. Check the inverter mounting orientation is correct. Prevent screws, wire fragments, other conductive bodies, oil or other flammable substances from entering the inverter. Do not drop the inverter, or subject it to impact. Use the inverter under the following environmental conditions:

Ambient temperature Ambient humidity 90%RH or less (non-condensing) Storage temperature

Ambience

Environment

Altitude, vibration

*Temperatures applicable for a short time, e.g. in transit.

-10°C to +50°C (14°F to 122°F) (non-freezing)

-20°C to +65°C * (-4°F to 149°F) Indoors (free from corrosive gas, flammable gas,

oil mist, dust and dirt) Maximum 1000m (3280.80feet) above sea level for standard operation. After that derate by 3% for every extra 500m (1640.40feet) up to 2500m (8202.00feet) (91%).

5.9m/s

CAUTION

or less (conforming to JIS C 0040)

A-2

(2) Wiring

CAUTION

Do not fit capacitive equipment such as power factor correction capacitor, radio noise filter or surge suppressor to the output of the inverter. 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

Check all parameters, and ensure that the machine will not be damaged by a sudden start-up. When the load GD2 is small (at the motor GD2 or smaller) for 400V from 1.5K to

3.7K, the 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 frecuency 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

CAUTION

WARNING

When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop. The [STOP] key is valid only when the appropriate function setting has been made. Prepare an emergency stop switch separately. Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly. 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. Do not modify the equipment.

CAUTION

The electronic overcurrent protection does not guarantee protection of the motor from overheating. Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected. Take measures to suppress harmonics. Otherwise power harmonics from the inverter may heat/damage the power capacitor and generator. When a 400V class motor is inverter-driven, it should be insulation-enhanced or surge voltages suppressed. Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. When parameter clear or all clear is performed, each parameter returns to the factory setting. Re-set the required parameters before starting operation. The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor and machine. In addition to the inverter's holding function, install a holding device to ensure safety. Before running an inverter which had been stored for a long period, always perform inspection and test operation.

A-3

(6) Maintenance, inspection and parts replacement

CAUTION

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

(7) Disposing of the inverter

CAUTION

Treat as industrial waste.

(8) General instructions

Many of the diagrams and drawings in this instruction manual show the inverter without a cover, or partially open. Never operate the inverter like this. Always replace the cover and follow this instruction manual when operating the inverter.

Wiring length 100m (328.08feet) maximum. (50m (164.04feet) maximum for the FR-S540-0.4K.)

CAUTION

• When the wiring length of the 0.1K or 0.2K is 30m (98.43feet) or more, use the carrier frequency to 1kHz.

• Use the carrier frequency of 1kHz when the wiring length of the FR-S540-0.4K,

0.75K is 30m (98.43feet) or more.

• The wiring length should be 30m (98.43feet) maximum when automatic torque boost is selected in Pr. 98 "automatic torque boost selection (motor capacity)". (Refer to page 109)

.5.2 Wiring instructions

1) Use insulation-sleeved crimping terminals for the power supply and motor cables.

2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.

3) After wiring, wire off-cuts must not be left in the inverter. Wire off-cuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling a control box etc., take care not to let wire off-cuts enter the inverter.

4) Use cables of the recommended size to make a voltage drop 2% maximum. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency.

5) For long distance wiring, the fast-response current limit function may be reduced or the devices connected to the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity of wiring. Therefore, note the maximum overall wiring length.

6) Electromagnetic wave interference The input/output (main circuit) of the inverter includes harmonic components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, install the optional FR-BIF radio noise filter (for use in the input side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.

7) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF option) in the output side of the inverter. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are connected, remove them. (When using the FR-BIF radio noise filter with a single-phase power supply, connect it to the input side of the inverter after isolating the T <L

8) Before starting rewiring or other work after performing operation once, check the voltage with a meter etc. more than 10 minutes after power-off. For some time after power-off, there is a dangerous voltage in the capacitor.

.5.4 Leakage current and installation of eart h leakag e ci r cui t br eaker

Due to static capacitances existing in the inverter I/O wiring and motor, leakage currents flow through them. Since their values depend on the static capacitances, carrier frequency, etc., take the following counter measures.

(1) To-ground leakage currents

Leakage currents may flow not only into the inverter's own line but also into the other line through the ground cable, etc. These leakage currents may operate earth leakage circuit breakers and earth leakage relays unnecessarily.

Counter measures

If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of the inverter. Note that motor noise increases. Selection of Soft-PWM control (Pr. 70) will make it unoffending. (Factory setting) By using earth leakage circuit breakers designed for harmonic and surge suppression (e.g. Mitsubishi's Progressive Super Series) in the inverter's own line and other line, operation can be performed with the carrier frequency kept high (with low noise).

(2) Line-to-line leakage currents

Harmonics of leakage currents flowing in static capacities between the inverter output cables may operate the external thermal relay unnecessarily.

Counter measures

Use the electronic overcurrent protection of the inverter. Decrease the carrier frequency. Note that motor noise increases. Selection of Soft-PWM (Pr. 70) makes it unoffending. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.

Installation and selection of no-fuse breaker

On the power receiving side, install a no-fuse breaker (NFB) to protect the primary wiring of the inverter. Which NFB to choose depends on the power supply side power factor (which changes with the power supply voltage, output frequency and load) of the inverter. Especially as the completely electromagnetic type NFB changes in operational characteristic with harmonic currents, you need to choose the one of a little larger capacity. (Check the data of the corresponding breaker.) For the earth leakage circuit breaker, use our product designed for harmonic and surge suppression (Progressive Super Series). (Refer to page 13 for the recommended models.)

breaker

When using the earth leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency:

Progressive Super Series (Type SP, CF, SF, CP) Rated sensitivity current: I∆n ≥ 10 × (lg1+Ign+lg2+lgm) Conventional NV series (Type CA, CS, SS produced prior to '91) Rated sensitivity current: I∆n ≥ 10 × {lg1+lgn+3 × (lg2+lgm)} lg1, lg2 : Leakage currents of cable

Ig1 Ign Ig2 Igm

CAUTION

• The earth leakage circuit breaker should be installed to the primary (power supply) side of the inverter.

• In the

connection neutral point grounded system, the sensitivity current becomes worse for ground faults in the inverter secondary side. Hence, the protective grounding of the load equipment should be 10Ω or less.

• When the breaker is installed in the secondary side of the inverter, it may be unnecessar ily oper at ed by har m onics if the effe ct ive v alu e i s le ss than the rat ing. In th is case, do not insta ll the brea ker since th e eddy curre nt and hy steresis loss in crease and the temperature rises.

Inverter Start/Stop Circuit Example

(1) Inverter's primary side magnetic contactor (MC)

On the inverter's primary side, it is recommended to provide an MC for the following purposes (Refer to page 13 for selection.):

1) To release the inverter from the power supply when the inverter's protective function is activated or when the drive is not functioning (e.g. emergency stop operation).

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

3) To rest the inverter for a long time. The control power supply for inverter is always running and consumes a little power. When stopping the inverter for a long time, switching inverter power off saves power slightly.

4) To separate the inverter from the power supply to ensure safety of maintenance/inspection work. As the inverter's primary MC is used for the above purposes, it is equivalent to the standard duty and select the one of class JEM1038-AC3 for the inverter input side current.

5.6 Regarding the installation of the power factor improvi ng reactor

When the inverter is installed near a large-capacity power transformer (500kVA or more at the wiring length of 10m (32.81feet) or less) or the power capacitor is to be switched, an excessive peak current will flow in the power supply input circuit, damaging the converter circuit. In such a case, always install the power factor improving reactor (FR-BEL or FR-BAL).

REMARKS

* When connecting the FR-BEL, remove the jumper across terminals P<+>-P1.

The wiring length between FR-BEL and inverter should be 5m (16.40feet) maximum and as short as possible. Use the cables which are equal in size to those of the main circuit. (Refer to page

11)

.5.7 Regarding noise and the installation of a noise filter

Some noise enters the inverter causing it to malfunction and others are generated by the inverter causing the malfunction of peripheral devices. Though the inverter is designed to be insusceptible to noise, it handles low-level signals, so it requires the following general counter measures to be taken.

General counter measures

Do not run the power cables (I/O cables) and signal cables of the inverter in parallel with each other and do not bundle them. Use twisted shield cables for the detector connecting and control signal cables and connect the sheathes of the shield cables to terminal SD. Ground the inverter, motor, etc. at one point. Capacitances exist between the inverter's I/O wiring, other cables, earth and motor, through which leakage currents flow to cause the earth leakage circuit breaker, earth leakage relay and external thermal relay to operate unnecessarily. To prevent this, take appropriate measures, e.g. set the carrier frequency in Pr. 72 to a low value, use an earth leakage circuit breaker designed for suppression of harmonics and surges, and use the electronic overcurrent protection built in the inverter.

Noise reduction examples

Install filter on inverter's input side.

Use the thickest possible ground cable. Use the cable whose size is equal to or

greater than that indicated in the following table, and minimize the cable length. The grounding point should be as near as possible to the inverter.

CAUTION

The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by the harmonic components of the inverter output. Also, since an excessive current flows in the inverter to activate overcurrent protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is driven by the inverter. To improve the power factor, insert a power factor improving reactor in the inverter's primary side or DC circuit. For full information, refer to page 18.

.5.10 Japanese power harmonic suppression guideline

Harmonic currents flow from the inverter to a power receiving point via a power transformer. The harmonic suppression guideline was established to protect other consumers from these outgoing harmonics.

1) [Harmonic suppression guideline for household appliances and general-purpose products] The "harmonic suppression guideline for household appliances and general-purpose products" issued by ex-Ministry of International Trade and Industry (present Ministry of Economy, Trade and Industry) in September, 1994 applies to the FR-S500 series other than the three-phase 400V class. By installing the FR-BEL or FR-BAL power factor improving reactor, this product complies with the "harmonic suppression techniques for transistorized inverters (input current 20A or less)" established by the Japan Electrical Manufacturers' Association.

2) "Harmonic suppression guideline for specific consumers" This guideline sets forth the maximum values of harmonic currents outgoing from a high-voltage or specially high-voltage consumer who will install, add or renew harmonic generating equipment. If any of the maximum values is exceeded, this guideline requires that consumer to take certain suppression measures.

1) Calculation of equivalent capacity (P0) of harmonic generating equipment The "equivalent capacity" is the capacity of a 6-pulse converter converted from the capacity of consumer's harmonic generating equipment and is calculated with the following equation. If the sum of equivalent capacities is higher than the limit in Table 3, harmonics must be calculated with the following procedure:

P0=Σ (Ki× Pi) [kVA]

Ki: Conversion factor (refer to Table 2) Pi: Rated capacity of harmonic

generating equipment* [kVA]

circuit type

*Rated capacity: Determined by the

capacity of the applied motor and found in Table 5. It should be noted that the rated capacity used here is used to calculate a generated harmonic amount and is different from the power supply capacity required for actual inverter drive.

2) Calculation of outgoing harmonic current Outgoing harmonic current = fundamental wave current (value converterd from

received power voltage) × operation ratio × harmonic content

.6.2 Wiring instructions

1) Terminals SD, SE and 5 are common to the I/O signals. These common terminals must not be earthed.

2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits (including the 200V relay sequence circuit).

3) The input signals to the control circuit are micro currents. When contacts are required, use two or more parallel micro signal contacts or a twin contact to prevent a contact fault.

.6.3 Changing the control logic

The input signals are set to sink logic for the Japanese and NA version, and to source logic for the EC version. To change the control logic, the connector under the setting dial must be moved to the other position.

Change the connector position

using tweezers, a pair of longnose pliers etc. Change the 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 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.

.7.1 Run (start ) and stop (STF, STR, STOP)

To start and stop the motor, first switch on the input power supply of the inverter (switch on the magnetic contactor, if any, in the input circuit during preparation for operation), then start the motor with the forward or reverse rotation start signal.

Power supply

Forward

Reverse

direction. Switch on both or switch off the start signal during operation to decelerate the inverter to a stop.

2) The frequency setting signal may either be given by entering 0 to 5VDC (or 0 to 10VDC) across frequency setting input terminal 2-5 or by setting the required values in Pr. 4 to Pr. 6 "multi-speed setting" (high, middle, low speeds). (For multi-speed operation, refer to page 32.)

Across STF-SD (STR)

3) After the start signal has been input, the inverter starts operating when the frequency setting signal reaches or exceeds the "starting frequency" set in Pr. 13 (factory-set to 0.5Hz). If the motor load torque is large or the "torque boost" set in Pr. 0 is small, operation may not be started due to insufficient torque until the inverter output frequency reaches about 3 to 6Hz. If the "minimum frequency" set in Pr. 2 (factory setting = 0Hz) is 6Hz, for example, merely entering the start signal causes the running frequency to reach the minimum frequency of 6Hz according to the "acceleration time" set in Pr. 7.

4) To stop the motor, operate the DC injection brake for the period of "DC injection brake operation time" set in Pr. 11 (factory setting = 0.5s) at not more than the DC injection brake operation frequency or at not more than 0.5Hz. To disable the DC injection brake function, set 0 in either of Pr. 11 "DC injection brake operation time" and Pr. 12 "DC injection brake voltage". In this case, the motor is coasted to a stop at not more than the frequency set in Pr. 10 "DC injection brake operation frequency" (0 to 120Hz variable) or at not more than 0.5Hz (when the DC dynamic brake is not operated).

5) If the reverse rotation signal is input during forward rotation or the forward rotation signal is input during reverse rotation, the inverter is decelerated and then switched to the opposite output without going through the stop mode.

(2) Three-wire type connection (STF, STR, STOP)

(

A three-wire type connection is shown on the right. Assign the start self-holding signal (STOP) to any of the input

Power supply

terminals. To make a reverse rotation start, set Pr. 63 to "- - -"

factory setting).

1) Short the signal STOP-SD to enable the start self-holding function. In this case, the forward/reverse rotation signal functions only as a start signal. (Note) Assign the stop signal to any of

Pr. 60 to Pr. 62 (input terminal function selection).

2) If the start signal terminal STF (STR)SD are shorted once, then opened, the start signal is kept on and starts the inverter. To change the rotation direction, short the start signal STR (STF)-SD once, then open it. (Note) Assign the stop signal to any of

Pr. 60 to Pr. 62 (input terminal function selection).

3) The inverter is decelerated to a stop by opening the signal STOP-SD once. For the frequency setting signal and the operation of DC dynamic brake at a stop time, refer to paragraphs 2) to 4) in (1) Two-wire type connection. The right diagram shows 3-wire type connection.

4) When the signal JOG-SD is shorted, the STOP signal is invalid and the JOG signal has precedence.

5) If the output stop signal MRS-SD is shorted, the self-holding function is not deactivated.

.7.2 Connection of frequency setting potentiometer and output

frequency meter (10, 2, 5, 4, AU)

The analog frequency setting input signals that may be entered are voltage and current signals. For the relationships between the frequency setting input voltages (currents) and output frequencies, refer to the following diagram. The frequency setting input signals are proportional to the output frequencies. Note that when the input signal is less than the starting frequency, the output frequency of the inverter is 0Hz. If the input signal of 5VDC (or 10V, 20mA) or higher is entered, the output frequency does not exceed the maximum output frequency.

.7.4 Indicator connection and adjustment

(1) Japanese version (FM)

The output frequency, etc. of the inverter can be indicated by a DC ammeter of 1mA full-scale deflection and maximum 300Ω internal resistance or a commercially available digital indicator which is connected across terminals FM-SD. The indicator can be calibrated from the operation panel or parameter unit. Note that the reading varies according to the wiring distance if the indicator is placed away from the inverter. In this case, connect a calibration resistor in series with the indicator as shown below and adjust until the reading matches the operation panel or parameter unit indication (indicator monitoring mode). Install the indicator within 200m (656.16feet) (50m (164.04feet) for the digital indicator) of the inverter and connect them by at least 0.3mm cables.

REMARKS

* Not needed when calibration is made using the calibration parameter C1 "FM

terminal calibration". This resistor is used when calibration must be made near the frequency meter for such a reason as a remote frequency meter. Note that the needle of the frequency meter may not deflect to full-scale when the calibration resistor is connected. In this case, use both the resistor and calibration parameter "C1".

CAUTION

• Refer to page 111 for the procedure of indicator adjustment.

Output waveform of terminal FM

The output signal of terminal FM has a pulse waveform as shown in the table below and the number of its pulses is proportional to the inverter output frequency. The output voltage (average voltage) is also proportional to the output frequency.

To adjust the reading of an analog indicator (ammeter), turn the calibration resistor to change the current. When using the operation panel or parameter unit for adjustment, change the pulse width of the output waveform (calibration parameter "C1") (adjust the current through the adjustment of the output voltage) to adjust the reading. (For details, refer to page

111.)

REMARKS

It is not recommended to use a voltage type indicator because it is easily affected by a voltage drop, induction noise, etc. and may not provide correct reading if the wiring distance is long.

Digital indicator

Since the digital indicator counts and displays the number of pulses, adjust it from the operation panel or parameter unit. The inverter output, at which the reference pulses of 1440 pulses/s are output, can be set in Pr. 55 when frequency monitoring is used as reference, or in Pr. 56 when current monitoring is used as reference.

[Example] 1. To set the output across FM-SD to 1440 pulses/s at the inverter output

frequency of 120Hz, set "120" (Hz) in Pr. 55. (Factory setting: 60Hz)

2. To set the output across FM-SD to 1440 pulses/s at the inverter output current of 15A, set "15" (A) in Pr. 56. (Factory setting: rated inverter current)

(2) NA and EC version (AM)

A full-scale 5VDC analog signal can be output from across terminals AM-5. The analog output level can be calibrated by the operation panel or parameter unit (FR-PU04). Terminal AM function selection can be set in Pr. 54 "AM terminal function selection". Terminal AM is isolated from the control circuit of the inverter. The cable length should not exceed 30m (98.44feet).

The output signal from terminal AM delays about several 100ms in output and therefore cannot be used as a signal for control which requires fast response.

Adjustment

Set the reference output value of the inverter which outputs the full-scale voltage 5VDC. Set it in Pr. 55 for frequency monitoring reference, or in Pr. 56 for current monitoring reference. Use the terminal AM output calibration parameter C1 to adjust the output voltage. [Example] 1. To set the output across AM-5 to 5VDC at the inverter output frequency

of 90Hz, set 90Hz in Pr. 55. (Factory setting: 50Hz)

2. To set the output across AM-5 to 5VDC at the inverter output current of 20A, set 20A in Pr. 56. (Factory setting: rated inverter current)

CAUTION

• Refer to page 113 for the procedure of indicator adjustment.

.7.5 Control circuit common terminals (SD, 5, SE)

Terminals SD, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL) and frequency output signal (FM). Terminal 5 is a common terminal for the frequency setting analog input signals and indicator terminal "AM". It should be protected from external noise using a shielded or twisted cable. Terminal SE is a common terminal for the open collector output terminal (RUN).

REMARKS

Terminal FM is provided for the FR-S520-0.1K to 3.7K (-R) (-C), FR-S520S-0.1K to

1.5K (-R) and FR-S510W-0.1K to 0.75 (-R), and terminal AM is provided for the FR-S520-0.1K to 3.7K-NA, FR-S520S-0.2K to 1.5K-EC (R) and FR-S510W-0.1K to

0.75K-NA.

.7.6 Signal inputs by contactless switches

If a transistor is used instead of a contacted switch as shown on the right, the input signals of the inverter can control terminals STF, STR, RH, RM, RL.

External signal input using transisto

REMARKS

1. When using an external transistor connected with the external power supply, use terminal PC to prevent a malfunction from occurring due to a leakage current. (Refer to page 25.)

Remote setting (RL, RM, RH signals): Setting "0, 1, 2"

By entering frequency commands into the RL, RM, RH and REX signals and turning on/off the corresponding signals, you can perform multi-speed operation (15 speeds). (For details, refer to page 32.) If the operation panel is away from the control box, you can perform continuous variable-speed operation with signal contacts, without using analog signals. (For details, refer to page 86.)

.8.5 Output shut-off (MRS signal): Setting "6"

Short the output stop terminal MRS-SD during inverter output to cause the inverter to immediately stop the output. Open terminals MRS-SD to resume operation in about 10ms. Terminal MRS may be used as described below:

(1) To stop the motor by

mechanical brake (e.g.

Motor coasted to stop

electromagnetic brake)

Terminals MRS-SD must be shorted when the mechanical brake is operated and be opened before motor restart.

Output frequenc y

(2) To provide interlock to disable

operation by the inverter

After MRS-SD have been shorted, the inverter cannot be operated if the start signal is given to the inverter.

Across MRS-SD Across STF-SD (STR)

(3) To coast the motor to stop

The motor is decelerated according to the preset deceleration time and is stopped by operating the DC injection brake at 3Hz or less. By using terminal MRS, the motor is coasted to a stop.

.8.6 External thermal relay input: Setting "7"

When the external thermal relay or thermal relay built in the motor is actuated, the inverter output is shut off and an alarm signal is given to keep the motor stopped to protect the motor from overheat. If the thermal relay contact is reset, the motor is not restarted unless the reset terminal RES-SD is shorted for more than 0.1s and then opened or power-on reset is performed. The function may therefore be used as an external emergency stop signal input.

.8.8 Reset signal: Setting "10"

Used to reset the alarm stop state established when the inverter's protective function is activated. The reset signal immediately sets the control circuit to the initial (cold) status, e.g. initializes the electronic overcurrent protection circuit. It shuts off the inverter output at the same time. During reset, the inverter output is kept shut off. To give this reset input, short terminals RES-SD for more than 0.1 second. When the shorting time i s lo n g, the operation panel or parameter unit displays the initial screen, which is not a fault. Operation is enabled after terminals RES-SD are opened. The reset terminal is used to reset the inverter alarm stop state. If the reset terminal is shorted, then opened while the inverter is running, the motor may be restarted during coasting (refer to the timing chart below) and the output may be shut off due to overcurrent or overvoltage. Setting either of "1" and "15" in reset selection Pr. 75 allows the accidental input of the reset signal during operation to be unaccepted. (For details, refer to page 94.)

.10 Design Information

1) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for commercial power supply-inverter switch-over. When there is a commercial power supply-inverter switch-over circuit as shown below, the inverter will be damaged by leakage current from the power supply due to arcs generated at the time of switch-over or chattering caused by a sequence error.

2) If the machine must not be restarted when power is restored af ter a power failure, provide a magnetic contactor in the inverter's primary circuit and also make up a sequence which will not switch on the start signal. If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the power is restored.

3) Since the input signals to the control circuit are on a low level, use two or more parallel micro signal contacts or a twin contact for contact inputs to prevent a contact fault.

4) Do not apply a large voltage to the contact input terminals (e.g. STF) of the control circuit.

5) Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp etc.

6) Make sure that the specifications and rating match the system requirements.

.3 Explanation of Functions (Parameters)

.3.1 Torque boost

Increase this value for use when the inverter-to-motor distance is long or motor torque is insufficient in the low

voltage

speed range (stall prevention is activated).

Motor torque in the low-frequency range can be adjusted to the load to increase the starting motor torque.

Assuming that the base frequency voltage is 100%, set the 0Hz voltage in %. Use the RT signal to switch between two different torque boosts. (Turn on the RT

signal to make Pr. 46 valid(*).)

REMARKS

* The RT signal acts as the second function selection signal and makes the other

second functions valid.

When using an inverter-dedicated motor (constant-torque motor), make setting as indicated below.

• FR-S520-0.1K to 0.75K ..... 6%, FR-S520-1.5K to 3.7K ..... 4%

• FR-S540-0.4K, 0.75K ..... 6%, FR-S540-1.5K ..... 4%,

FR-S540-2.2K, 3.7K ..... 3%

• FR-S520S-0.1K to 0.75K ..... 6%, FR-S520S-1.5K ..... 4%

• FR-S510W-0.1K to 0.75K ..... 6%

If you leave the factory setting as it is and change the Pr. 71 value to the setting for use of the constant-torque motor, the Pr. 0 setting changes to the above value.

CAUTION

Selecting automatic torque boost control makes this parameter setting invalid.

•

A too large setting may cause the motor to overheat or result in an overcurrent

•

trip. The guideline is about 10% at the greatest.

Use Pr. 1 to set the upper limit of the output frequency. If the frequency of the frequency command entered is higher than the setting, the output frequency is clamped at the maximum frequency.

Use Pr. 2 to set the lower limit of the output frequency.

REMARKS

When using the potentiometer (frequency setting potentiometer) connected across terminals 2-5 to perform operation above 60Hz <50Hz>, change the Pr. 1 and Pr. 38 (Pr. 39 when using the potentiometer across terminals 4-5) values.

CAUTION

When the Pr. 2 setting is higher than the Pr. 13 "starting frequency" value, note that the motor will run at the set frequency by merely switching the start signal on, without entering the command frequency.

Setting is enabled when Pr. 30 = "1".

In Pr. 3 and Pr. 47, set the base frequency (motor's rated frequency). Use the RT signal to switch between these two different base frequencies. (Turn on the RT signal to make Pr. 47 valid.) (*)

When running the standard motor, generally set the "base frequency" to the rated frequency of the motor. When running the motor using commercial power supplyinverter switch-over operation, set the base frequency to the same value as the power supply frequency.

When the frequency given on the motor's rating plate is only "50Hz", always set the "base frequency" to "50Hz". Leaving the base frequency unchanged from "60Hz" may make the voltage too low and the torque insufficient, resulting in an overload trip. Special care must be taken when "1" is set in Pr. 14 "load pattern selection".

Set the base voltage (e.g. rated voltage of motor) in Pr. 19.

CAUTION

1. Set 60Hz in Pr. 3 "base frequency" when using a Mitsubishi constant-torque motor.

2. When automatic torque boost is selected, Pr. 47 is invalid. When automatic torque boost is selected, setting "- - -" or "888" in Pr. 19 uses the rated output voltage.

REMARKS

* The RT signal serves as the second function selection signal and makes the

other second functions valid.

.3.4 Multi-speed opera t ion

Used to switch between the predetermined running speeds.

Any speed can be selected by merely switching on/off the corresponding

contact signals (RH, RM, RL, REX signals).

By using these functions with Pr. 1 "maximum frequency" and Pr. 2 "minimum

frequency", up to 17 speeds can be set.

This function is valid in the external operation mode or in the combined

operation mode which is available when Pr. 79 = "3" or "4".

Set the rated current [A] of the motor. (Normally set the rated current at 50Hz if the motor has both 50Hz and 60Hz rated current.)

Setting "0" in Pr. 9 disables electronic thermal O/L relay (motor protective function). (The protective function of the inverter is activated.)

When using a Mitsubishi constant-torque motor, first set "1" in Pr. 71 "applied motor" to choose the 100% continuous torque characteristic in the low-speed range. Then, set the rated motor current 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 overcurrent protection. Install an external thermal relay to each motor.

• When the difference between the inverter and motor capacities is large and the setting is small, the protective characteristics of the electronic overcurrent protection will be deteriorated. In this case, use an external thermal relay.

• A special motor cannot be protected by the electronic overcurrent protection. Use an external thermal relay.

.3.12 Stall prevention function and current limit function

You can make settings to disable stall prevention caused by overcurrent and to disable the fast-response current limit (which limits the current to prevent the inverter from resulting in an overcurrent trip if an excessive current occurs due to sudden load variation or ON-OFF, etc. in the output side of the running inverter).

•Stall prevention If the current exceeds the limit value, the output frequency of the inverter is automatically varied to reduce the current.

•Fast-response Current limit

If the current exceeds the limit value, the output of the inverter is shut off to prevent an overcurrent.

CAUTION

•* When "Operation not continued for OL signal output" is selected, the "OLT" alarm code (stopped by stall prevention) is displayed and operation stopped. (Alarm stop display "

• If the load is heavy, the lift is predetermined, or the acceleration/deceleration time

is short, the stall prevention may be activated and the motor not stopped in the preset acceleration/deceleration time. Therefore, set optimum values to the Pr. 21 and stall prevention operation level.

• When the fast-response current limit has been set in Pr. 21 (factory setting),

torque will not be provided at the Pr. 22 setting of 170% or higher. At this time, make setting so that the fast-response current limit is not activated.

• In vertical lift applications, make setting so that the fast-response current limit is

not activated. Torque may not be produced, causing a gravity drop.

CAUTION

Always perform test operation. Stall prevention operation performed during acceleration may increase the acceleration time. Stall prevention operation performed during constant speed may cause sudden speed changes. Stall prevention operation performed during deceleration may increase the deceleration time, increasing the deceleration distance.

.3.13 Stall prevention

Set the output current level at which the output frequency will be adjusted to prevent the inverter from stopping due to overcurrent etc.

During high-speed operation above the rated motor frequency, acceleration

may not be made because the motor current does not increase. To improve the operating characteristics of the motor in this case, the stall prevention level can be reduced in the high frequency region. This function is effective for performing operation up to the high speed range on a centrifugal separator etc. Normally, set 60Hz <50Hz> in Pr. 28 "stall prevention operation reduction starting frequency" and 100% in Pr. 23.

REMARKS

When the fast-response current limit is set in Pr. 21 "stall prevention function selection" (factory setting), do not set any value above 170% in Pr. 22. The torque will not be developed by doing so. If the Pr. 22 value is set to higher than 170%, make setting in Pr. 21 to disable the fast-response current limit.

Acceleration is made to the set frequency linearly. (Factory setting)

For machine tool spindle applications, etc. Used when acceleration/deceleration must be made in a short time to a high-speed region of not lower than the base frequency. Acceleration/deceleration is made in a pattern where fb (base frequency) acts as the inflection point of an S shape, and you can set the acceleration/deceleration time which matches the motor torque reduction in the constant-output operation region of not lower than the base frequency. For conveyor and other load colla pse preven tion applications, etc. Since acceleration/deceleration is always made in an S shape from f2 (current frequency) to f1 (target frequency), this function eases shock produced at acceleration/deceleration and is effective for load collapse prevention, etc.

Restart voltage rise time

Pr. 58 setting

Generally, this setting will pose no problems.

CAUTION

Automatic restart operation after instantaneous power failure is a reduced voltage starting system in which the output voltage is risen gradually at the preset frequency independently of the coasting speed of the motor. It is a system which outputs the output frequency before an instantaneous power failure, unlike the motor coasting speed detection system (speed search system) used by the FR-E transistorized inverters. Hence, if the instantaneous power failure time is 0.2s or longer, the frequency before an instantaneous power failure cannot be stored in memory and the inverter restarts at 0Hz. The SU and FU signals are not output dur ing a re st art. Th ey are output after the restart cushion time has elapsed.

CAUTION

When automatic restart after instantaneous power failure has been selected, the motor and machine will start suddenly (after the restart coasting time has elapsed) after occurrence of an instantaneous power failure. Stay away from the motor and machine. When you have selected automatic restart after instantaneous power failure, apply in easily visible places the CAUTION seals supplied to the instruction manual (basic).

• The frequency can be varied by RH (acceleration) and RM (deceleration) between 0 and the maximum frequency (Pr. 1 setting).

• When the acceleration or deceleration signal switches on, the set frequency varies according to the slope set in Pr. 44 "second acceleration/deceleration time" or Pr. 45 "second deceleration time". The output frequency acceleration and deceleration times are as set in Pr. 7 "acceleration time" and Pr. 8 "deceleration time", respectively. Therefore, the longer preset times are used to vary the actual output frequency.

• If the start signal (STF or STR) is off, turning on the acceleration (RH) or deceleration (RM) signal varies the preset frequency.
