MAINTENANCE AND INSPECTION

SPECIFICATIONS

Thank you for choosing this Mitsubishi Inverter. This Instruction Manual (applied) provides instructions for advanced use of the FR-F700 series inverters.

Incorrect handling might cause an unexpected fault. Before using the inverter, always read this instruction manual and the instruction manual (basic) [IB-0600176ENG] packed with the product carefully to use the equipment to its optimum.

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you have read through 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

The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed because these are important to personal safety.

1. Electric Shock Prevention

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.

WARNING

• 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, inspection or switching EMC filter ON/OFF

connector, power must be switched OFF. To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring, inspection or switching EMC filter ON/OFF connector 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.

• Setting 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 replace the cooling fan while power is on. It is

dangerous to replace the cooling fan while power is on.

• Do not touch the printed circuit board with wet hands. You may

get an electric shock.

• When measuring the main circuit capacitor capacity (Pr. 259

Main circuit capacitor life measuring = "1"), 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

CAUTION

• Inverter must be installed on a nonflammable wall without

holes (so that nobody touches the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.

• If the inverter has become faulty, the inverter power must be

switched OFF. A continuous flow of large current could cause a fire.

• Do not connect a resistor directly to the DC terminals P/+ and

N/-. Doing so could cause a fire.

3. Injury Prevention

CAUTION

• The voltage applied to each terminal must be the ones

specified 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 since the inverter will be extremely hot. Doing so can cause burns.

4. Additional Instructions

Also the following points must be noted to prevent an accidental failure, injury, electric shock, etc.

(1) Transportation and installation

CAUTION

• The product must be transported in correct method that

corresponds 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. This can result in breakdowns.

• When carrying the inverter, do not hold it by the front cover or

setting 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 flammable 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.

Surrounding air temperature

Ambient humidity 90% RH or less (non-condensing) Storage temperature -20°C to +65°C

Atmosphere

Environment

Altitude, vibration

*1 Temperature applicable for a short time, e.g. in transit. *2 2.9m/s

or less for the 185K or more.

-10°C to +50°C (non-freezing)

Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)

Maximum 1000m above sea level for standard operation. 5.9m/s2 or less at 10 to

55Hz (directions of X, Y, Z axes) *2

A-1

(2) Wiring

• Do not install a power factor correction capacitor, surge

suppressor or capacitor type filter 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) Test operation and adjustment

CAUTION

• Before starting operation, each parameter must be confirmed

and adjusted. A failure to do so may cause some machines to make unexpected motions.

(4) Operation

• Any person must stay away from the equipment when the retry

function is set as it will restart suddenly after trip.

• Since pressing key may not stop output depending on

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 confirmed 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 inverter.

WARNING

(5) Emergency stop

• A safety backup such as an emergency brake must be

provided 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 identified and removed before turning ON the power of the breaker.

• When any protective function is activated, appropriate

corrective action must be taken, and the inverter must be reset before resuming operation.

(6) Maintenance, inspection and parts replacement

CAUTION

• Do not carry out a megger (insulation resistance) test on the

control circuit of the inverter. It will cause a failure.

(7) Disposing of the inverter

CAUTION

• The inverter must be treated as industrial waste.

General instructions

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.

CAUTION

• The electronic thermal relay function does not guarantee

protection 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 filter 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 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.

Inverter and peripheral devices

Three-phase AC power supply

Use within the permissible power supply specifications of the inverter.

(Refer to page 294)

Programmable controller

Moulded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB), fuse

The breaker must be selected carefully since an in-rush current flows in the inverter at power on.

(Refer to page 4)

Magnetic contactor(MC)

Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shorten.

(Refer to page 4)

Reactor (FR-HAL, FR-HEL)

Reactors (option) should be used when power harmonics measures are taken, the power factor is to be improved or the inverter is installed near a large power supply system (1000kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. For the 55K or less, remove the jumpers across terminals P/+-P1 to connect to the DC reactor.

(Refer topage 4.)

RS-485 terminal block

The inverter can be connected with computers such as programmable controller. It supports Mitsubishi inverter protocol and Modbus-RTU (binary) protocol.

Inverter (FR-F700)

The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as possible within the permissible range. Especially when mounting the inverter inside an enclosure, take cautions of the surrounding air temperature. (Refer to page 10) Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit to protect them from noise.(Refer to page 14) Refer to page 15 for the built-in EMC filter.

Installation of the inverter and

enclosure design

1.4 Installation of the inverter and enclosure design

When an inverter enclosure is to be designed and manufactured, heat generated by contained equipment, etc., the environment of an operating place, and others must be fully considered to determine the enclosure structure, size and equipment layout. The inverter unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.

1.4.1 Inverter installation environment

As the inverter installation environment should satisfy the standard specifications indicated in the following table, operation in any place that does not meet these conditions not only deteriorates the performance and life of the inverter, but also causes a failure. Refer to the following points and take adequate measures.

Environmental standard specifications of inverter

Item Description

Ambient humidity 90% RH maximum (non-condensing)

Atmosphere Free from corrosive and explosive gases, dust and dirt

*1 2.9m/s2 or less for the 185K or more.

or less at 10 to 55Hz (directions of X, Y, Z axes) *1

5.9m/s

(1) Temperature

The permissible surrounding air temperature of the inverter is between -10°C and +50°C. Always operate the inverter within this temperature range. Operation outside this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following measures so that the surrounding air temperature of the inverter falls within the specified range.

1)Measures against high temperature

• Use a forced ventilation system or similar cooling system. (Refer to page 10.)

• Install the enclosure in an air-conditioned electrical chamber.

• Block direct sunlight.

• Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.

• Ventilate the area around the enclosure well.

2)Measures against low temperature

• Provide a space heater in the enclosure.

• Do not power off the inverter. (Keep the start signal of the inverter off.)

3)Sudden temperature changes

• Select an installation place where temperature does not change suddenly.

• Avoid installing the inverter near the air outlet of an air conditioner.

• If temperature changes are caused by opening/closing of a door, install the inverter away from the door.

(2) Humidity

Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical breakdown. The insulation distance specified in JEM1103 "Control Equipment Insulator" is defined as humidity 45 to 85%.

1)Measures against high humidity

• Make the enclosure enclosed, and provide it with a hygroscopic agent.

• Take dry air into the enclosure from outside.

• Provide a space heater in the enclosure.

2)Measures against low humidity What is important in fitting or inspection of the unit in this status is to discharge your body (static electricity) beforehand and keep your body from contact with the parts and patterns, besides blowing air of proper humidity into the enclosure from outside.

3)Measures against condensation Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outsideair temperature changes suddenly. Condensation causes such faults as reduced insulation and corrosion.

• Take the measures against high humidity in 1).

• Do not power off the inverter. (Keep the start signal of the inverter off.)

Installation of the inverter and

enclosure design

(3) Dust, dirt, oil mist

Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to moisture absorption of accumulated dust and dirt, and in-enclosure tempearture rise due to clogged filter. In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time. Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Countermeasures

• Place in a totally enclosed enclosure. Take measures if the in-enclosure temperature rises. (Refer to page 10.)

• Purge air. Pump clean air from outside to make the in-enclosure pressure higher than the outside-air pressure.

(4) Corrosive gas, salt damage

If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the relays and switches will result in poor contact. In such places, take the measures given in Section (3).

(5) Explosive, flammable gases

As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure. In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and has passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to avoid installation in such places and install the inverter in a non-hazardous place.

(6) Highland

Use the inverter at the altitude of within 1000m. If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric strength.

(7) Vibration, impact

The vibration resistance of the inverter is up to 5.9m/s2 (2.9m/s2 for the 185K or more) at 10 to 55Hz frequency (directions of X, Y, Z axes) and 1mm amplitude. Vibration or impact, if less than the specified value, applied for a long time may make the mechanism loose or cause poor contact to the connectors. Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.

Countermeasures

• Provide the enclosure with rubber vibration isolators.

• Strengthen the structure to prevent the enclosure from resonance.

• Install the enclosure away from sources of vibration.

enclosure design

1.4.2 Cooling system types for inverter enclosure

From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the permissible temperatures of the in-enclosure equipment including the inverter. The cooling systems are classified as follows in terms of the cooling calculation method.

1) Cooling by natural heat dissipation from the enclosure surface (Totally enclosed type)

2) Cooling by heat sink (Aluminum fin, etc.)

3) Cooling by ventilation (Forced ventilation type, pipe ventilation type)

4) Cooling by heat exchanger or cooler (Heat pipe, cooler, etc.)

• For replacing the cooling fan of the FR-F740-185K or more, 30cm of space is necessary in front of the inverter. Refer to page 284 for fan replacement.

(3) Inverter mounting orientation

Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.

(4) Above the 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.

(5) Arrangement of multiple inverters

When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown in the right figure (a). When it is inevitable to arrange them vertically to minimize space, take such

Inverter

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 enclosure

(a) Horizontal arrangement

size.

(6) Placement of ventilation fan and inverter

Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow. (Air passes through areas of low resistance. Make an airway and airflow plates to expose the inverter to cool air.)

CAUTION

· The power supply cables must be connected to R/L1, S/L2, T/L3. (Phase sequence needs not to be matched.) Never connect the power cable to the U, V, W of the inverter. Doing so will damage the inverter.

· Connect the motor to U, V, W. At this time, turning on the forward rotation switch (signal) rotates the motor in the counterclockwise direction when viewed from the motor shaft.

· When wiring the inverter main circuit conductor of the 250K or more, tighten a nut from the right side of the conductor. When wiring two wires, place wires on both sides of the conductor. (Refer to the drawing below.) For wiring, use bolts (nuts) provided with the inverter.

and a screw for earthing (grounding).

The line voltage drop can be calculated by the following formula:

WIRING

line voltage drop [V]=

3 × wire resistance[mΩ/m] × wiring distance[m] × current[A]

1000

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque reduction) in the low speed range.

CAUTION

· Tighten the terminal screw to the specified torque. A screw that has been tighten too loosely can cause a short circuit or malfunction. A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.

· Use crimping terminals with insulation sleeve to wire the power supply and motor.

(2) Notes on earthing (grounding)

z Always earth (ground) the motor and inverter.

1)Purpose of earthing (grounding) Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use. An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an insulating material that can shut off a leakage current completely, and actually, a slight current flow into the case. The purpose of earthing (grounding) the case of an electrical apparatus is to prevent operator from getting an electric shock from this leakage current when touching it. To avoid the influence of external noises, this earthing (grounding) is important to audio equipment, sensors, computers and other apparatuses that handle low-level signals or operate very fast.

2)Earthing (grounding) methods and earthing (grounding) work As described previously, earthing (grounding) is roughly classified into an electrical shock prevention type and a noise-affected malfunction prevention type. Therefore, these two types should be discriminated clearly, and the following work must be done to prevent the leakage current having the inverter's high frequency components from entering the malfunction prevention type earthing (grounding): (a) If possible, use (l) independent earthing (grounding) in figure below for the inverter. If independent earthing

(grounding) is not available, use (ll) joint earthing (grounding) in the figure below which the inverter is connected with the other equipment at an earthing (grounding) point. The (lll) common earthing (grounding) as in the figure below, which inverter shares a common earth (ground) cable with the other equipment, must be avoided. A leakage current including many high frequency components flows in the earth (ground) cables of the inverter and inverter-driven motor. Therefore, use the independent earthing (grounding) and separated the earthing (grounding) cable of the inverter from equipments sensitive to EMI. In a high building, it may be effective to use the EMI prevention type earthing (grounding) connecting to an iron structure frame, and electric shock prevention type earthing (grounding) with the independent earthing (grounding) together.

(b) 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.

indicated in the above table on the previous page.

(d) The earthing (grounding) point should be as near as possible to the inverter, and the earthing (grounding)

wire length should be as short as possible.

(e) Run the earth (ground) cable as far away as possible from the I/O wiring of equipment sensitive to noises

and run them in parallel in the minimum distance.

(ground) cable should be of not less than the size

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. Refer to page 53 for measures against deteriorated insulation.

CAUTION

· Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray capacitances of the wiring, leading to a malfunction of the overcurrent protective function or fast response current limit function or a malfunction or fault of the equipment connected on the inverter output side. If fast-response current limit function malfunctions, disable this function. (For Pr.156 Stall prevention operation selection, refer to page 77.)

· For details of Pr. 72 PWM frequency selection , refer to page 158. (When using an optional sine wave filter (MT-BSL/BSC) for the 75K or more, set "25" in Pr.72 (2.5kHz)).

Multi-speed can be selected according to the combination of RH, RM and RL signals.

Turn on the JOG signal to select Jog operation (initial setting) and turn on the start signal (STF or STR) to start Jog operation.

Turn on the RT signal to select second function. When the second function such as "second torque boost" and "second V/F (base frequency)" are set, turning on the RT signal selects these functions.

Turn on the MRS signal (20ms or more) to stop the inverter output. Use to shut off the inverter output when stopping the motor by electromagnetic brake.

Used to reset fault output provided when fault occurs. Turn on the RES signal for more than 0.1s, then turn it off. Initial setting is for reset always. By setting Pr.75, reset can be set to enabled only at fault occurrence. Inverter recovers about 1s after the reset is released.

Terminal 4 is valid only when the AU signal is turned on. (The frequency setting signal can be set between 0 and 20mADC.) Turning the AU signal on makes terminal 2 (voltage input) invalid.

AU terminal is used as PTC input terminal (thermal protection of the motor). When using it as PTC input terminal, set the AU/PTC switch to PTC.

When the CS signal is left on, the inverter restarts automatically at power restoration. Note that restart setting is necessary for this operation. In the initial setting, a restart is disabled.

Control circuit terminal

Terminals SD, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Do not earth(ground) these terminals. Avoid connecting the terminal SD and 5 and the terminal SE and 5. Terminal SD is a common terminal for the contact input terminals (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES, AU, CS) and frequency output signal (FM). The open collector circuit is isolated from the internal control circuit by photocoupler. Terminal 5 is a common terminal for frequency setting signal (terminal 2, 1 or 4) and analog output 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, SU, OL, IPF, FU). The contact input circuit is isolated from the internal control circuit by photocoupler.

(2) Signal inputs by contactless switches

The contacted input terminals of the inverter (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be controlled using a transistor instead of a contacted switch as shown on the right.

1) It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals.

If the cable gauge used is 1.25mm the cables are run improperly, resulting in an operation panel contact fault.

2) The maximum wiring length should be 30m (200m for terminal FM).

3) Use two or more parallel micro-signal contacts or twin contacts to prevent a contact faults when using contact inputs since the control circuit input signals are micro-currents.

4) 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).

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

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

EMC and leakage currents

3.1 EMC and leakage currents

3.1.1 Leakage currents and countermeasures

Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current. Therefore, take the following measures. Select the earth leakage circuit breaker according to its rated sensitivity current, independently of the carrier frequency setting.

(1) To-earth (ground) leakage currents

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

z Suppression technique

⋅ If the carrier frequency setting is high, decrease the Pr. 72 PWM frequency selection setting. Note that motor noise

increases.Selecting Pr. 240 Soft-PWM operation selection makes the sound inoffensive.

⋅ By using earth leakage circuit breakers designed for harmonic and surge suppression in the inverter's own line and

other line, operation can be performed with the carrier frequency kept high (with low noise).

z To-earth (ground) leakage currents

⋅ Take caution as long wiring will increase the leakage current. Decreasing the carrier frequency of the inverter

reduces the leakage current.

⋅ Increasing the motor capacity increases the leakage current. The leakage current of the 400V class is larger than

that of the 200V class.

(2) Line-to-line leakage currents

Harmonics of leakage currents flowing in static capacitances between the inverter output cables may operate the external thermal relay unnecessarily. When the wiring length is long (50m or more) for the 400V class small-capacity model (7.5K or less), the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to the rated motor current increases.

increases.Selecting Pr. 240 Soft-PWM operation selection makes the sound inoffensive. 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.

zInstallation and selection of moulded case circuit breaker

Install a moulded case circuit breaker (MCCB) on the power receiving side to protect the wiring of the inverter input side. Select the MCCB according to the inverter input side power factor (which depends on the power supply voltage, output frequency and load). Especially for a completely electromagnetic MCCB, one of a slightly large capacity must be selected since its operation characteristic varies with harmonic currents. (Check it in the data of the corresponding breaker.) As an earth leakage circuit breaker, use the Mitsubishi earth leakage circuit breaker designed for harmonics and surge suppression.

EMC and leakage currents

(3) Selection of rated sensitivity current of earth leakage circuit breaker

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

⋅ Breaker designed for harmonic and surge

suppression Rated sensitivity current: IΔn ≥ 10 × (Ig1 + Ign + Igi + Ig2 + Igm)

⋅ Standard breaker

Rated sensitivity current: IΔn ≥ 10 × {Ig1 + Ign + Igi + 3 × (Ig2 + Igm)}

PRECAUTIONS FOR USE OF THE INVERTER

EMC and leakage currents

3.1.2 EMC measures

Some electromagnetic noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices. Though the inverter is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques. Also, since the inverter chops outputs at high carrier frequency, that could generate electromagnetic noises. If these electromagnetic noises cause peripheral devices to malfunction, EMI measures should be taken to suppress noises. These techniques differ slightly depending on EMI paths.

1)Basic techniques

⋅ 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 pair shielded cables for the detector connection and control signal cables, and connect the sheathes

of the shield cables to terminal SD.

⋅ Earth (Ground) the inverter, motor, etc. at one point.

2)Techniques to reduce electromagnetic noises that enter and malfunction the inverter (Immunity measures) When devices that generate many electromagnetic noises (which use magnetic contactors, magnetic brakes, many relays, for example) are installed near the inverter and the inverter may be malfunctioned by electromagnetic noises, the following measures must be taken: ⋅ Provide surge suppressors for devices that generate many electromagnetic noises to suppress electromagnetic

noises.

⋅ Fit data line filters to signal cables. ⋅ Earth (Ground) the shields of the detector connection and control signal cables with cable clamp metal.

3)Techniques to reduce electromagnetic noises that are radiated by the inverter to malfunction peripheral devices (EMI measures) Inverter-generated electromagnetic noises are largely classified into those radiated by the cables connected to the inverter and inverter main circuits (I/O), those electromagnetically and electrostatically induced to the signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.

Propagation Path Measures

When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal cables are run near the inverter, the devices may be malfunctioned by air-propagated electromagnetic noises. The following measures must be taken: (1) Install easily affected devices as far away as possible from the inverter.

radiated noises. (6) Use shield cables as signal cables and power cables and run them in individual metal conduits to

produce further effects.

When the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction noises may be propagated to the signal cables to malfunction the devices and the following measures must be taken: (1) Install easily affected devices as far away as possible from the inverter.

When the power supplies of the peripheral devices are connected to the power supply of the inverter in the same line, inverter-generated noises may flow back through the power supply cables to malfunction

the devices and the following measures must be taken: (1) Set the EMC filter ON/OFF connector of the inverter to the ON position. (Refer to page 15) (2) Install the common mode filter (FR-BLF, FR-BSF01) to the power cables (output cable) of the inverter.

When a closed loop circuit is formed by connecting the peripheral device wiring to the inverter, leakage

currents may flow through the earth (ground) cable of the inverter to malfunction the device. In such a case, disconnection of the earth (ground) cable of the device may cause the device to operate properly.

3.1.3 Power supply harmonics

The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path. Take the following countermeasure suppression techniques. z The differences between harmonics and noises are indicated below:

Item Harmonics Noise

Environment To-electric channel, power impedance To-space, distance, wiring path

Quantitative understanding Theoretical calculation possible Random occurrence, quantitative grasping difficult

Measures

The harmonic current generated from the inverter to the input side differs according to various conditions such as the wiring impedance, whether a reactor is used or not, and output frequency and output current on the load side. For the output frequency and output current, we understand that they should be calculated in the conditions under the rated load at the maximum operating frequency.

The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by the high frequency 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. For power factor improvement, install a reactor on the inverter input side or in the DC circuit.

3.1.4 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 harmonic currents. The three-phase 200V input specifications 3.7kW or less are previously covered by "Harmonic suppression guideline for household appliances and general-purpose products" and other models are covered by "Harmonic suppression guideline for consumers who receive high voltage or special high voltage". However, the general-purpose inverter has been excluded from the target products covered by "Harmonic suppression guideline for household appliances and general-purpose products" in January 2004. Later, this guideline was repealed on September 6, 2004. All capacities of all models are now target products of "Harmonic suppression guideline for consumers who receive high voltage or special high voltage".

"Guideline for specific consumers" This guideline sets forth the maximum values of harmonic currents outgoing from a high-voltage or especially highvoltage 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:

6Active filter

Install an AC reactor (FR-HAL) on the AC side of the inverter or a DC reactor (FR-HEL) on its DC side or both to suppress outgoing harmonic currents.

The converter circuit is switched on-off to convert an input current waveform into a sine wave, suppressing harmonic currents substantially. The high power factor converter (FRHC, MT-HC) is used with the standard accessory.

When used with a series reactor, the power factor improving capacitor has an effect of absorbing harmonic currents.

Use two transformers with a phase angle difference of 30° as in - , - combination to provide an effect corresponding to 12 pulses, reducing low-degree harmonic currents.

A capacitor and a reactor are used together to reduce impedances at specific frequencies, producing a great effect of absorbing harmonic currents.

This filter detects the current of a circuit generating a harmonic current and generates a harmonic current equivalent to a difference between that current and a fundamental wave current to suppress a harmonic current at a detection point, providing a great effect of absorbing harmonic currents.

PRECAUTIONS FOR USE OF THE INVERTER

Installation of a reactor

3.2 Installation of a reactor

When the inverter is connected near a large-capacity power transformer (1000kVA or more) or when a power capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent this, always install the AC reactor (FR-HAL)

REMARKS

The wiring length between the FR-HEL and inverter should be 5m maximum and minimized. Use the same wire size as that of the power supply wire (R/L1, S/L2, T/L3). (Refer to page 20)

3.3 Power-off and magnetic contactor (MC)

(1) Inverter input side magnetic contactor (MC)

On the inverter input side, it is recommended to provide an MC for the following purposes.

(

Refer to page 4 for selection.)

1)To release the inverter from the power supply when the fault occurs or when the drive is not functioning (e.g. emergency stop operation). To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure

3)While the power is ON, inverter is consuming a little power even during inverter stop. 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 JEM1038-AC3MC for the inverter input side current when making an emergency stop during normal operation.

REMARKS

Since repeated inrush current at power on will shorten the life of the converter circuit (switching life is 100 million times (about 500,000 times for the 200V class 37K or more)), frequent starts/stops must be avoided. Turn on/off the inverter start controlling terminals (STF, STR) to run/stop the inverter.

• Inverter start/stop circuit example

As shown on the left, always use the start signal

To the

(ON or OFF of STF (STR) signal) to make a start

*1 When the power supply is 400V class, install a step-

down transformer.

*2 Connect the power supply terminals R1/L11, S1/L21

of the control circuit to the primary side of the MC to hold an alarm signal when the inverter's protective circuit is activated. At this time, remove jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21. (Refer to page 24 for removal of the jumper.)

(2) Handling of the inverter output side magnetic contactor

Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the magnetic contactor is turned on while the inverter is operating, overcurrent protection of the inverter and such will activate. When an MC is provided to switch to a commercial power supply, for example, it is recommended to use bypass operation Pr. 135 to Pr. 139 (Refer to page 233).

Inverter-driven 400V class motor

3.4 Inverter-driven 400V class motor

In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter, consider the following measures:

Measures

It is recommended to take either of the following measures:

(1) Rectifying the motor insulation and limiting the PWM carrier frequency according to the wiring length

For the 400V class motor, use an insulation-enhanced motor Specifically,

1)Specify the "400V class inverter-driven insulation-enhanced motor".

2)For the dedicated motor such as the constant-torque motor and low-vibration motor, use the "inverter-driven, dedicated motor".

3)Set Pr. 72 PWM frequency selection as indicated below according to the wiring length

50m or less 50m to 100m exceeding 100m

Pr. 72 PWM frequency selection 15(14.5kHz) or less 9(9kHz) or less 4(4kHz) or less

(2) Suppressing the surge voltage on the inverter side

Connect the surge voltage suppression filter (FR-ASF-H) to the 55K or less and the sine wave filter (MT-BSL/BSC) to the 75K or more on the inverter output side.

CAUTION

· For details of Pr. 72 PWM frequency selection , refer to page 158. (When using an optional sine wave filter (MT-BSL/BSC) for the or more, set "25" in Pr.72 (2.5kHz).)

· For explanation of surge voltage suppression filter (FR-ASF-H) and sine wave filter (MT-BSL/BSC), refer to the manual of each option.

PRECAUTIONS FOR USE OF THE INVERTER

Precautions for use of the inverter

3.5 Precautions for use of the inverter

The FR-F700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items.

(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.

(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 offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.

(4) Use cables of the 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. Refer to page 20 for the recommended cable sizes.

(5) The overall wiring length should be 500m maximum.

Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity of the wiring. Therefore, note the overall wiring length. (Refer to page 23.)

(6) Electromagnetic wave interference

The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, set the EMC filter valid to minimize

interference.

(7) Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side.

This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices is installed, immediately remove it.

(8) 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.

(9) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules.

· Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation resistance may damage the inverter modules.

· Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-on. Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.

(10) Do not use the inverter input side magnetic contactor to start/stop the inverter.

Always use the start signal (ON/OFF of STF and STR signals) to start/stop the inverter.

(11) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.

Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected incorrectly to short terminals 10E-5.

(Refer to page

15)

(Refer to page

14)

(12) Provide electrical and mechanical interlocks for MC1 and

MC2 which are used for bypass operation. When the wiring is incorrect or if there is an electronic bypass circuit as shown on the right, the inverter will be damaged when the power supply is connected to the inverter U, V, W terminals due to arcs generated at the time of switch-over or chattering caused by a sequence error.

Precautions for use of the inverter

(13) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the

inverter's input side 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.

(14) Instructions for overload operation

When performing an operation of frequent start/stop of the inverter, increase/decrease in the temperature of the transistor element of the inverter may repeat due to a continuous flow of large current, shortening the life from thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing bound current, starting current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and the inverter may not start. Therefore, increase the inverter capacity to have enough allowance for current.

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

(16) If electromagnetic noise generated from the inverter causes frequency setting signal to fluctuate and motor rotation

speed to be unstable when changing motor speed with analog signal, the following countermeasures are effective.

· Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.

· Run signal cables as far away as possible from power cables (inverter I/O cables).

· Use shield cables as signal cables.

· Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

PRECAUTIONS FOR USE OF THE INVERTER

Failsafe of the system which uses the

inverter

3.6 Failsafe of the system which uses the inverter

When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter

fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products,

provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when the

inverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter,

without using the inverter, is enabled even if the inverter fails.

(1) Interlock method which uses the inverter status output signals

By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be

detected.

1) Check by the output of the inverter fault signal

When the fault occurs and the inverter trips, the fault output

signal (ALM signal) is output (ALM signal is assigned to

terminal A1B1C1 in the initial setting).

Check that the inverter functions properly.

In addition, negative logic can be set (on when the inverter is

normal, off when the fault occurs).

2) Checking the inverter operating status by the inverter

operation ready completion signal

Operation ready signal (RY signal) is output when the

inverter power is on and the inverter becomes operative.

Check if the RY signal is output after powering on the

inverter.

3) Checking the inverter operating status by the start signal

input to the inverter and inverter running signal.

The inverter running signal (RUN signal) is output when the

inverter is running (RUN signal is assigned to terminal RUN

in the initial setting).

Check if RUN signal is output when inputting the start signal

to the inverter (forward signal is STF signal and reverse

signal is STR signal). For logic check, note that RUN signal

is output for the period from the inverter decelerates until

output to the motor is stopped, configure a sequence

considering the inverter deceleration time

4) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal.

The output current detection signal (Y12 signal) is output when the inverter operates and currents flows in the motor.

Check if Y12 signal is output when inputting the start signal to the inverter (forward signal is STF signal and reverse

signal is STR signal). Note that the current level at which Y12 signal is output is set to 120% of the inverter rated current

in the initial setting, it is necessary to adjust the level to around 20% using no load current of the motor as reference with

Pr.150 Output current detection level.

For logic check, as same as the inverter running signal (RUN signal), the inverter outputs for the period from the inverter

decelerates until output to the motor is stopped, configure a sequence considering the inverter deceleration time.

y When using various signals, assign functions to Pr. 190 to Pr.

the left.

CAUTION

⋅ Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions. Make

setting after confirming the function of each terminal.

(2) Backup method outside the inverter

Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure

status of the inverter itself. For example, when the inverter CPU fails, even if the interlock is provided using the inverter

fault signal, start signal and RUN signal, there is a case where a fault signal is not output and RUN signal is kept output

even if an inverter fault occurs.

Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the

backup system such as checking up as below according to the level of importance of the system.

1) Start signal and actual operation check

Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to

the inverter and detected speed of the speed detector or detected current of the current detector. Note that the motor

current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the

start signal turns off. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it is

recommended to check the three-phase current when using the current detector.

2) Command speed and actual operation check

Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command

and detected speed of the speed detector.

⋅ Use the second torque boost when changing the torque boost according to application or when using multiple

motors by switching between them by one inverter.

⋅ Pr. 46 Second torque boost is valid when the RT signal turns on.

REMARKS

⋅ The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 117) ⋅ The RT signal is assigned to the RT terminal in the default setting. By setting "3" to any of Pr. 178 to Pr. 189 (Input terminal function

selection), you can assign the RT signal to the other terminal.

CAUTION

⋅ Increase the setting when the distance between the inverter and motor is long or when motor torque is insufficient in the low-

speed range. If the setting is too large, an overcurrent trip may occur.

⋅ The Pr. 0 and Pr. 46 settings are valid only when V/F control is selected. ⋅ When using the inverter dedicated motor (constant-torque motor) with the 5.5K or 7.5K, set the torque boost value to 2%. If the

initial set Pr. 71 value is changed to the setting for use with a constant-torque motor, the Pr. 0 setting changes to the corresponding value in above.

⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Please

make setting after confirming the function of each terminal.

(2) Stall prevention operation signal output and output timing adjustment (OL signal, Pr. 157)

⋅ When the output current exceeds the stall prevention operation level and stall prevention is activated, the stall

prevention operation signal (OL signal) turns on for longer than 100ms. When the output current falls to or below the stall prevention operation level, the output signal turns off.

⋅ Use Pr. 157 OL signal output timer to set whether the OL signal is output immediately or after a preset period of time. ⋅ This operation is also performed when the regeneration avoidance function (overvoltage stall) is executed.

setting "3 (positive logic) or 103 (negative logic)" to any of Pr. 190 to Pr. 196 (output terminal function selection).

CAUTION

· If the frequency has fallen to 0.5Hz by stall prevention operation and remains for 3s, a fault (E.OLT) appears to shutoff the inverter output.

· Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions. Please make setting after confirming the function of each terminal.

400Hz Output frequency (Hz)

⋅ During high-speed operation above the rated motor frequency, acceleration may not be made because the motor

current does not increase. If operation is performed in a high frequency range, the current at motor lockup becomes smaller than the rated output current of the inverter, and the protective function (OL) is not executed if the motor is at a stop. To improve the operating characteristics of the motor in this case, the stall prevention level can be reduced in the high frequency range. This function is effective for performing operation up to the high-speed range on a centrifugal separator etc. Normally, set 60Hz in Pr. 66 and 100% in Pr. 23.

⋅ In Pr. 48, you can set the stall prevention operation level at the output frequency from 0Hz to that set in Pr. 49.

During acceleration, however, the operation level is as set in Pr. 22.

always set to "50Hz". Leaving the base frequency unchanged from "60Hz" may make the voltage too low and the torque insufficient. It may result in an inverter trip due to overload. Caution must be taken especially when Pr. 14 Load pattern selection = "1" (variable torque load).

⋅ When using the Mitsubishi constant-torque motor, set Pr. 3 to

60Hz.

(2) Set multiple base frequencies (Pr. 47)

Set the frequency when the motor rated torque is generated. (50Hz/60Hz)

Set the base frequency when the RT signal is on.

⋅ When you want to change the base frequency when switching two motors with one inverter, use the Pr. 47 Second V/F

(base frequency).

⋅ Pr. 47 Second V/F (base frequency) is valid when the RT signal is on.

REMARKS

⋅ The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 118) ⋅ In the initial setting, the RT signal is assigned to the RT terminal. By setting "3" to any of Pr. 178 to Pr. 189 (Input terminal function

selection), you can assign the RT signal to the other terminal.

V/F pattern

(3) Base frequency voltage setting (Pr. 19)

⋅ Use Pr. 19 Base frequency voltage to set the base voltage (e.g. rated motor voltage). ⋅ If the setting is equal to or less than the power supply voltage, the maximum output voltage of the inverter is as set in

Pr. 19.

⋅ Pr. 19 can be utilized in the following cases.

(a) When regeneration frequency is high (e.g. continuous regeneration)

During regeneration, the output voltage becomes higher than the reference and may cause an overcurrent trip (E.OC) due to an increased motor current.

(b) When power supply voltage variation is large

When the power supply voltage exceeds the rated voltage of the motor, speed variation or motor overheat may be caused by excessive torque or increased motor current.

CAUTION

⋅ When Pr. 71 Applied motor is set to "2" (adjustable 5 points V/F characteristic), the Pr. 47 setting becomes invalid. In addition, you

cannot set "8888" or "9999" in Pr. 19.

⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Make

setting after confirming the function of each terminal.
