Safety precautions

Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance and inspection. Ensure you have sound knowledge of the device and familiarize yourself with all safety information and precautions before proceeding to operate the inverter.

Safety precautions are classified into the following two categories in this manual.

Failure to heed the information indicated by this symbol may lead to dangerous conditions, possibly resulting in death or serious bodily injuries.

Failure to heed the information indicated by this symbol may lead to dangerous conditions, possibly resulting in minor or light bodily injuries and/or substantial property damage.

Failure to heed the information contained under the CAUTION title can also resu lt in s erious consequences. These safety precautions are of utmost importance and must be observed at all times.

Operation

 Be sure to install the terminal block cover before turning the power on. Do not remove the

cover while power is applied. Otherwise electric shock could occur.

 Do not operate switches with wet hands.

Doing so could cause electric shock.

 If the retry function has been selected, the inverter may automatically restart and drive

the motor depending on the cause of tripping. (Design the machinery or equipment so that human safety is ensured after restarting.)

 If the stall prevention function (current limiter), automatic deceleration, and overload

prevention control have been selected, the inverter may operate at an acceleration /deceleration time or frequency different from the set ones. Design the machine so that safety is ensured even in such cases.

Otherwise an accident could occur.

 The STOP key is only effective when function setting (Function code F02) is established

to enable the STOP key. Prepare an emergency stop switch separately. If you disable the STOP key priority function and enable operation by external commands, you cannot emergency-stop the inverter using the STOP key on the built-in keypad.

 If an alarm reset is made with the operation signal turned on, a sudden start will occur.

Ensure that the operation signal is turned off in advance.

Otherwise an accident could occur.

1. Operating Environment

Install the inverter in an environment that satisfies the requirements listed in

Table 1.1 Environmental Requirements

Table 1.2 Output Current Derating Factor

in Relation to Altitude

2. Installing the Inverter

(1) Mounting base

The temperature of the heat sink may rise up to approx. 90°C during operation of the inverter, so the inverter should be mounted on a base made of material that can withstand temperatures of this level.

Install the inverter on a base made of metal or other non-flammable material.

A fire may result with other material.

(2) Clearances

Ensure that the minimum clearances indicated in Figure 2.1 are maintained at all times. When installing the inverter in the panel of your system, take extra care with ventilation inside the panel as the temperature around the inverter tends to increase.

(Note 1)

When inverters are mounted side-by-

side without any gap between them, the ambient temperature should be within the range from -10 to +40°C.

(Note 2)

Do not install the inverter in an

environment where it may be exposed to cotton waste or moist dust or dirt which will clog the heat sink in the inverter. If the inverter is to be used in such an environment, install it in the panel of your system or other dustproof containers.

(Note 3)

If you use the inverter in an altitude

above 1000 m, you should apply an output current derating factor as listed in Table 2.2.

When mounting two or more inverters When mounting two or more inverters in the same unit or panel, basically lay them out s ide by

side. As long as the ambient temperature is 40°C or lower, inverters can be mounted side by side without any clearance between them. When the inverters necessarily mounted one above the other be sure to separate them with a partition plate or the like so that any heat radiating from an inverter will not affect the one(s) above.

(3) Mounting direction

Secure the inverter to the mounting base with four screws or bolts (M4) so that the FVR-Micro logo faces outwards. (FVR0.4AS1S-7 and

FVR0.75AS1S-7 use t wo screws or bolts.) Tighten those

screws or bolts perpendicular to the mounting base. (Maximum torque is 0.6N∙m)

Do not mount the inverter upside down or horizontally. Doing so will reduce the heat dissipation efficiency of the inverter and cause the overheat protection function to

operate, so the inverter will not run.

Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink.

This may result in a fire or accident.

3. Wiring

Follow the procedure below. (In the following description, the inverter has already been installed.)

3.1 Removing and mounting the terminal block covers

(1) Loosen the screw securing the control circuit terminal block cover. (2) Insert your finger in the cutout (near "PULL") in the bottom of the control circuit terminal

block cover, and then pull the cover towards you.

(3) Hold both sides of the main circuit terminal block cover between thumb and forefinger and

slide it towards you.

(4) After performing wiring, mount the main circuit terminal block cover and control circuit

terminal block cover in the reverse order of removal.

3.4 Wi ring for main circuit terminals and grounding terminals

Follow the procedure below. Figure 3.1 illustrates the wiring procedure with peripheral equipment.

Wiring procedure

①

Grounding terminal G*

② Inverter output terminals (U, V, and W) and grounding terminal G*1 ③ Braking resistor connection terminals (P and DB)*2 ④ Main circuit power input terminals (L1/R, L2/S and L3/T) or (L1/L and L2/N)

Use either one of these two grounding terminals on the main circuit terminal block.

Perform wiring as necessary.

Figure 3.1 Wiring procedures for Peripheral Equipment

Page 9

The wiring procedure for the FVR0.75AS1S-4 is given below as an example. For other inverter types, perform wiring in accordance with their individual terminal arrangement.

①

Grounding terminal ( G)

Be sure to ground either of the two grounding terminals for safety and noise reduction. It is stipulated by the Electric Facility Technical Standard that all metal frames of electrical equipment must be grounded to avoid electric shock, fire and other disasters.

Grounding terminals should be grounded as follows:

1) Ground the inverter in compliance with the national or local electric code.

2) Connect a thick grounding wire with a large surface area. Keep the wiring length as short as possible.

②

Inverter output terminals, U, V, W and grounding terminal ( G)

1) Connect the three wires of the three-phase motor to terminals U, V, and W, aligning phases each other.

2) Connect the grounding wire of terminals U, V, and W to the grounding terminal ( G).

 The wiring length between the inverter and motor should not exceed 50 m. If it exceeds

50 m, it is recommended that an output circuit filter (option) be inserted.

 Do not use one multicore cable to connect several inverters with motors.



Do not connect a phase-advancing capacitor or surge absorber to the inverter’s output

lines (secondary circuit).

 If the wiring length is long, the stray capacitance between the wires will increase,

resulting in an outflow of the leakage current. It will activate the overcurrent protecti on, increase the leakage current, or will not assure the accuracy of the current display. In the worst case, the inverter could be damaged.

 If more than one motor is to be connected to a single inverter, the wiring length should

be the total length of the wires to the motors.

Page 10

 Driving 400 V series motor

 If a thermal relay is installed in the path between the inverter and the motor to protect

the motor from overheating, the thermal relay may malfunction even with a wiring length shorter than 50 m. In this situation, add an output circuit filter (option) or lower the carrier frequency (Function code F26: Motor sound (Carrier frequency)).

 If the motor is driven by a PWM-type inverter, surge voltage that is generated by

switching the inverter component may be superimposed on the output voltage and may be applied to the motor terminals. Particularly if the wiring length is long, the surge voltage may deteriorate the insulation resistance of the motor. Consider any of the following measures.

- Use a motor with insulation that withstands the surge voltage.

- Connect an output circuit filter (option) to the output terminals (secondary circuits) of the inverter.

- Minimize the wiring length between the inverter and motor (10 to 20 m or less).

③

Braking resistor terminals, P and DB

1) Connect terminals P and DB of a braking resistor (option) to terminals P and DB on the main circuit terminal block.

2) Arrange the inverter and braking resistor to keep the wiring length to 5 m or less and twist the two wires or route them together in parallel.

④

Main circuit power input terminals, L1/R, L2/S, and L3/T ( for thre e-phase volta ge input) or

L1/L and L2/N (for single-phase voltage i nput )

1) For safety, make sure that the molded case circuit breaker (MCCB) or magnetic contactor (MC) is turned off before wiring the main circuit power input terminals.

2) Connect the main circuit power supply wires (L1/R, L2/S and L3/T or L1/L and L2/N) to the input terminals of the inverter via an MCCB or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)*, and MC if necessary.

It is not necessary to align phases of the power supply wires and the input terminals of the inverter with each other.

* With overcurrent protection

It is recommended that a magnetic contactor be inserted which can be manually

activated. This is to allow you to disconnect the inverter from the power supply in an emergency (e.g., when the protective function is activated) so as to prevent a failure or accident

from causing the secondary problems.

4. Names and Functions of Keypad Components

As shown in the figure at right, the keypad consists of a four-digit 7-segment LED monitor, a potentiometer (POT), and six keys. The keypad allows you to start and stop the motor, monitor running status, configure the function code data, check I/O signal states, and display maintenance information and alarm information.

(Note 1) Install a recommended molded case circuit breaker (MCCB) or a residual-current-

perated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent

prot

ection) in the primary circuit of the inverter to protect wiring. Do not use an MCCB or

RCD/ELCB whose capacity exceeds the recommended rated current.

(Note 2) A magnetic contactor (MC) should, if necessary, be mounted independent of the MCCB or

ELCB to

cut off the power fed to the inverter. MCs or solenoids that will be installed close to

the inverter require surge absorbers to be connected in parallel to their coils.

(Note 4)

(Note 6)

For the wiring of the control

circuit, use shielded or twisted wires. When shielded wires are

9. Function Code Tables

Function codes enable the FVR-Micro of inverters to be set up to match your system requirements. Each function code consists of a 3-letter alphanumeric string. The first letter is an alphabet that

identifies its group and the following two letters are numerals that identify each individual code in the group. The function codes are classified into seven groups: Fundamental Functions (F codes), Extension Terminal Functions (E codes), Control Functions (C codes), Motor 1 Parameters (P codes), High Performance Functions (H codes), Application Functions (J codes) and Link Functions (y codes). To determine the property of each function code, set data to the function code.

(This manual only shows F functions, refer to the instruction on website for more functions,)

Changing, validating, and saving function code data when the motor is running

Function codes are indicated by the following based on whether they can be changed or not when the inverter is running:

Notation Change when running Validating and saving function code data

Possible

If the data of the codes marked with Y* is changed, the change will immediately take effect; however, the change is not saved

into the inverter's memory. To save the change, press the (Function/Data) key. If you press the (Program/Reset) key without pressing the (Function/Data) key to exit the current

state, then the changed data will be discarded and the pre vious

data will take effect for the inverter operation.

Possible

The data of the codes marked with Y can be changed with the

or keys regardless of whether the motor is running or not.

Pressing the (Function/Data) key will make the change

effective and save it into the inverter's memory.

N Impossible

—

Using negative logic f or programmable I/O terminals The negative logic signaling system can be used for digital input terminals and transistor output

terminals by setting the function code data specifying the properties for those terminals. Negative logic refers to the inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An active-ON signal (the function takes effect if the terminal is short-circuited.) in the normal logic system is functionally equivalent to active-OFF signal (the function takes effect if the terminal is opened.) in the negative logic system. An active-ON signal can be switched to active-OFF signal, and vice versa, with the function code data setting.

To set the negative logic system for an input or output terminal, enter data of 1000s (by adding 1000 to the data for the normal logic) in the corresponding function code.

Example: "Coast to a stop" command BX assigned to any of digital input terminals [X1] to [X3] using any of function codes E01 through E03.

Function code data BX

7 Turning BX ON causes the motor to coast to a stop. (Active ON)

1007 Turning BX OFF causes the motor to coast to a stop. (Active OFF)

10. Compliance with standards

10.1 Conformity to the Low Voltage Directive in the EU

If installed according to the guidelines given below, inverters marked with CE are considered as compliant with the Low Voltage Directive in Europe.

1. The ground terminal G should always be connected to the ground. Do not use only a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)* as the sole method of electric shock protection. Be sure to use ground wires whose size is greater than power supply lines.

* With overcurrent protection.

2. When used with the inverter, a molded case circuit breaker (MCCB), residual-currentoperated protective device (RCD)/earth leakage circuit breaker (ELCB) or magnetic contactor (MC) should conform to the EN or IEC standards.

3. When you use a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) for protection from electric shock in direct or indirect contact power lines or nodes, be sure to install t ype B of RCD/ELCB on the input (primary) of the inverter if the power source is three-phase 200/400 V. For single-phase 200 V power supplies, use typ e A.

When you use no RCD/ELCB, take any other protective measure that isolates the electric

equipment from other equipment on the same power supply line using double or reinforced insulation or that isolates the power supply lines connected to the electric equipment using an isolation transformer.

4. The inverter should be used in an environment that does not exceed Pollution Degree 2 requirements. If the environment conforms to Pollution Degree 3 or 4, install the inverter in an enclosure of IP54 or higher.

5. I nstall the inverter, input or output filter in an enclosure with minimum degree of protection of IP2X (Top surface of enclosure shall be minimum IP4X when it can be easily accessed), to prevent human body from touching directly to live parts of these equipment.

6. To make an inverter with no integrated EMC filter conform to the EMC directive, it is necessary to connect an external EMC filter to the inverter and install them properly so that the entire equipment including the inverter conforms to the EMC directive.

7. Do not connect any copper wire directly to grounding terminals. Use crimp terminals with tin or equivalent plating to connect them.

8. When using inverters at an altitude of more than 2000 m (6600 ft), note that the basic insulation applies to the insulation degree of the control circuitry. At an altitude of more than 3000 m (9800 ft), inverters cannot be used.

9. The power supply mains neutral has to be earthed for the three-phase 400 V class inverter.

10. The inverter has been tested with EN61800-5-1 5.2.3. 6.3 Shor t-circuit Current Test under the following conditions.

Short-circuit current in the supply: 5 kA Maximum 240 V

Maximum 480 V

10.1 Conformity to the Low Voltage Directive in the EU (Continued)

Use wires listed in IEC60364-5-52.

MCCB: Molded case circuit breaker

RCD: Residual-current-operated protective device

ELCB: Earth leakage circuit breaker

*1 The frame size and model of the MCCB or RCD/ELCB (with overcurrent protection) will vary,

depending on the power transformer capacit y. Refer to the related technical documentation for details.
