Guideline for Suppressing Harmonics in Home Electric and General-purpose Appliances

Our three-phase, 208 V class series inverters of 5 HP or less (FRENIC-Eco series) were the products of which were restricted by the "Guideline for Suppressing Harmonics in Home Electric an d General-purpose Appliances" (established in September 1994 and revised in October 1999) issued by the Ministry of Economy, Trade and Industry.

The above restriction, however, was lifted when the Guideline was revised in January 2004. Since then, the inverter makers have individually imposed voluntary restrictions on the harmonics of their products.

We, as before, recommend that you connect a reactor (for suppressing harmonics) to your inverter. As a reactor, select a "DC REACTOR" introduced in this manual. For use of the other reactor, please inquire of us about detailed specifications.

Japanese Guideline for Suppressing Harmonics by Customers Receiving High Voltage or Special High Voltage

Refer to this manual, Appendix B for details on this guideline.

Safety precautions

Read this manual and the FRENIC-Eco Instruction Manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance and inspection. Ensure you have sound knowledge of the product 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 result in serious consequences. These safety precautions are of utmost importance and must be observed at all times.

This product is not designed for use in appliances and machinery on which lives depend. Consult your Fuji Electric representative before considering the FRENIC-Eco series of inverters for equipment and machinery related to nuclear power control, aerospace uses, medical uses or transportation. When the product is to be used with any machinery or equipment on which lives depend or with machinery or equipment which could cause serious loss or damage should this product malfunction or fail, ensure that appropriate safety devices and/or equipment are installed.

 Precautions for Use

Driving a 460 V general-purpose motor

When driving a 460 V general-purpose motor with an inverter using extremely long wires, damage to the insulation of the motor may occur. Use an output circuit filter (OFL) if necessary after checking with the motor manufacturer. Fuji motors do not require the use of output circuit filters because of their reinforced insulation.

In running generalpurpose motors

Torque characteristics and temperature rise

Vibration

Noise

Explosion-proof motors

Submersible motors and pumps

When the inverter is used to run a general-purpose motor, the temperature of the motor becomes higher than when it is operated using a commercial power supply. In the low-speed range, the cooling effect will be weakened, so decrease the output torque of the motor.

When an inverter-driven motor is mounted to a machine, resonance may be caused by the natural frequencies of the machine system.

Note that operation of a 2-pole motor at 60 Hz or higher may cause abnormal vibration.

* The use of a rubber coupling or vibration dampening rubber is

recommended.

* Use the inverter's jump frequency control feature to skip the resonance

frequency zone(s).

When an inverter is used with a general-purpose motor, the motor noise level is higher than that with a commercial power supply. To reduce noise, raise carrier frequency of the inverter. Operation at 60 Hz or highe r can also res ult in hig her level of wind roaring sound.

When driving an explosion-pro of motor with an inverter, use a combination of a motor and an inverter that has been approved in advance.

These motors have a higher rated current than general-purpose motors. Select an inverter whose rated output current is higher than that of the motor.

These motors differ from general-purpose motors in thermal characteristics. Set a low value in the thermal time constant of the motor when setting the electronic thermal overcurrent protection (for motor).

In running special motors

Brake motors

Geared motors

Synchronous motors

Single-phase motors

For motors equipped with parallel-connected brakes, their braking power must be supplied from the inverter’s primary circuit. If the brake power is connected to the inverter's output circuit by mistake, the brake will not work.

Do not use inverters for driving m otors equippe d with series -connected brakes. If the power transmission mechanism uses an oil-lubricated gearbox or speed

changer/reducer, then continuous m otor operation at low speed may cause poor lubrication. Avoid such operation.

It is necessary to take special measures suitable for this motor type. Contact your Fuji Electric representative for details.

Single-phase motors are not suitable for inverter-driven variable speed operation. Use three-phase motors.

iii

Environmental conditions

Installation location

Installing an MCCB or RCD/GFCI

Installing an MC in the secondary circuit

Use the inverter within the ambient temperature range from -10 to +50°C (14 to 122°F).

The heat sink and braking resistor of the inverter may become hot under certain operating conditions, so install the inverter on nonflammable material such as metal.

Ensure that the installation location meets the environmental conditions specified in Chapter 8, Section 8.4 "Operating Environment and Storage Environment."

Install a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/ground fault circuit interrupter (GFCI) (with overcurrent protection) in the primary circuit of each inverter to protect the wiring. Ensure that the circuit breaker capacity is equivalent to or lower than the recommended capacity.

If a magnetic contactor (MC) is installed in the inverter's output (secondary) circuit for switching the motor to commercial power or for any other purpose, ensure that both the inverter and the motor are completely stopped before you turn the MC on or off.

Remove a surge killer integrated with the magnet contactor in the inverter's output (secondary) circuit.

Combination with peripheral devices

Installing an MC in the primary circuit

Protecting the motor

Discontinuance of power-factor correcting capacitor

Discontinuance of surge killer

Reducing noise

Do not turn the magnetic contactor (MC) in the primary circuit on or off more than once an hour as an inverter failure may result.

If frequent starts or stops are required during motor operation, use (FWD)/(REV) signals or the RUN/STOP key.

The electronic thermal feature of the inverter can protect the motor. The operation level and the motor type (general-purpose motor, inverter motor) should be set. For high-speed motors or water-cooled motors, set a small value for the thermal time constant.

If you connect the motor thermal relay to the motor with a long wire, a high-frequency current may flow into the wiring stray capacitance. This may cause the thermal relay to trip at a current lower than the set value. If this happens, lower the carrier frequency or use the output circuit filter (OFL).

Do not connect power-factor correcting capacitors to the inverter’s primary circuit. (Use the DC reactor to improve the inverter power factor.) Do not use power-factor correcting capacitors in the inverter’s output (secondary) circuit. An overcurrent trip will occur, disabling motor operation.

Do not connect a surge killer to the inverter's output (secondary) circuit.

Use of a filter and shielded wires is typically recommended to satisfy EMC Directives.

Refer to Appendices, App. A "Advantageous Use of Inverters (Notes on electrical noise)" for details.

If an overvoltage trip occurs while the inverter is stopped or operated under

Measures against surge currents

light load, it is assumed that the surge current is generated by open/close of the phase-advancing capacitor in the power system.

* Connect a DC reactor to the inverter. When checking the insulation resistance of the inverter, use a 500 V megger

Megger test

and follow the instructions contained in th e FRENIC-Eco Instructio n Manual, Chapter 7, Section 7.5 "Insulation Test."

Wiring

Control circuit wiring length

Wiring length between inverter and motor

Wire size

When using remote control, limit the wiring length between the inverter and operator box to 66ft (20 m) or less and use twisted pair or shielded wire.

If long wiring is used between the inverter and the motor, the inverter may overheat or trip due to overcurrent because a higher harmonics current flows into the stray capacitance between each phase wire. Ensure that the wiring is shorter than 164ft (50 m). If this length must be exceeded, lower the carrier frequency or install an output circuit filter (OFL).

Select wires with a sufficient capacity by referring to the current value or recommended wire size.

Selecting inverter capacity

Transportation and storage

Wir e type

Grounding Securely ground the inverter using the grounding terminal.

Driving general-purpose motor

Driving special motors

When transporting or storing inverters, follow the procedures and select locations that meet the environmental conditions listed in the FRENIC-Eco Instruction Manual, Chapter 1, Section 1.3 "Transportation" and Section 1.4 "Storage Environment."

Do not share one multi-core cable in order to connect several inverters with motors.

Select an inverter according to the applicable motor ratings listed in the standard specifications table for the inverter.

When high starting torque is required or quick acceleration or deceleration is required, select an inverter with a capacity one size greater than the standard. Refer to Chapter 7, Section 7.1 "Selecting Motors and Inverters" for details.

Select an inverter that meets the following condition: Inverter rated current > Motor rated current

1.1 Features

Chap. 1

Default functions for fans and pumps

 Switching motor pow er between commercial lines and inverter outputs

The FRENIC-Eco series of inverters is equipped with built-in sequence control logic that supports starting of the motor via the commercial lines by using an external sequence and switches the motor power between commercial lines and inverter outputs. This feature simplifies the user’s power control system configuration.

In addition to this Fuji’s standard switching sequence, an auto-switching sequence is also available upon occurrence of an inverter alarm.

The schematic diagram below shows a typical sequence control circuit externally configured for an effective application of the sequence control logic.

GFCI or MCCB

Refer to function codes E01 to E05 in Section 9.2.2 "E codes" and J22 in Section 9.2.6 "J codes."



 Full PID control functions

The PID control has the "slow flowrate stop" and "de viation alarm/absolute value alarm outp ut" functions. It also supports a variety of manual speed (frequency) commands to make a balance-less and bump-less switching available that automatically adjusts the output frequency against the frequency command.

Further, the PID control has an anti-reset wind-up function for prevention of overshooting, as well as supporting PID output limiter and integration hold/reset signals, facilitating the adjustment necessary for PID control.

BOUT FRENIC-Eco

Refer to the PID Frequency Command Generator in Section 4.8, function codes E01 to E05, E20 to



E22, E24, and E27 in Section 9.2.2 "E codes," and J01 to J06, J10 to J13, and J15 to J19 in Section

9.2.6 "J codes."

1-1

 Slow flow rate stop function

A new function called slow flowrate stop is now added to the low limiter for securing the minimum operation speed of a fan and pum p, etc., whereby the o peration w ill st op if the fl owrate dro ps and rem ains below the low limit for a certain length of time. This, combined with PID control, contributes to more energy-saving operation.

Refer to function codes E20 to E22, E24, and E27 in Section 9.2.2 "E codes" and J15, J16, and J17 in



Section 9.2.6 "J codes."

 Command loss detection

The analog frequency command is monitored an d when an abnormal condi tion is detected, an alarm signal is output. Further, if in a critical system such as an air conditioner for an important facility, an abnormal condition is detected in the circuit handling the analog frequency command source, the system will be stopped or will continue its operation at the specified speed (at the specified percentage of the command just before the detection of the abnormal condition).

Refer to function codes E20 to E22, E24, E27, and E65 in Section 9.2.2 "E codes."



1-2

 Low output torque detection

A low output torque detection signal is asserted in the event of sudden decrease in torque as a result of an abnormal condition such as the belt being broken between the m otor and t he load (e .g., a belt- driv en fan). This signal, which indicates abnormal condi tion s occu rring in the facility (load), can therefore be used as maintenance information.

 Continuous operation at momentary power failure

You can choose either tripping or automatic restart in the event of a momentary power failure. You can choose starting at the frequency at the momentary power failure occurrence or starting at 0 Hz, according to the requirement. Further, you can choose a control mode to prolong the running time utilizing the kinetic energy due to the load’s moment of inertia during the momentary power failure.

 Auto search for idling motor's speed

The auto search feature helps the idling motor start smoothly, by setting an auto search frequency. When the motor is in idling state due to natural con vection, momentary power failure or other similar situations, the inverter can automatically search for the current motor speed and direction and start/restart the motor smoothly from the frequency that can be harmonized with the current motor speed and rotation, without stopping it. For restart after a recovery from the momentary power failure, you hav e a choice of two frequencies--the frequency saved at the power failure and the starting frequency.

1.2 Control System

This section gives you a general overview of inverter control systems and features specific to the FRENIC-Eco series of inverters.

As shown in Figure 1.4, the converter s ection converts the i nput commercial power to DC power by means of a full-wave rectifier, which is then used to charge the DC link bus capacitor (reservoir capacitor). The inverter portion modulates the electric energy charged in the DC link bus capacitor by Pulse Width Modulation (PWM) and feeds the output to the motor. (The PWM switching frequency is called the "Carrier Frequency.") The voltage applied to the motor terminals has a waveform shown on the left-hand side ("PWM voltage waveform") of Figure 1.3, consisti ng of alternati ng cycles of po sitive pulse tra ins and negative pulse trains. The current running through the motor, on the other hand, has a fairly smooth alternating current (AC) waveform shown on the right-hand side ("Current waveform") of Figure 1.3, thanks to the inductance of the motor coil inducta nce. The c ontrol lo gic section c ontrols the PWM so as to bring this current waveform as close to a sinusoidal waveform as possible.

PW M voltage waveform Current waveform

Figure 1.3 Output Voltage and Current Waveform of the Inverter

For the frequency command given in the control logic, the accelerat or/decelerator processor cal culates the acceleration/deceleration rate required by run/stop control of the motor and transfers the calculated r esults to the 3-phase voltage processor directly or via the V/f pattern generator whose output drives the PWM block to switch the power gates.

Refer to Section 4.7 "Drive Command Controller" for details.



The FRENIC-Eco series features simplified magnetic flux estimation integrated in the V/f pattern generator section. This feature automatically adjusts the voltage applied to the motor according to the motor load so as to make the motor generate more stable and higher torque even during low speed operation.

The control logic section, which is the very brain of the inverter, allows you to customize the inverter's driving patterns throughout the function code data settings.

Chap. 3 OPERATION USING THE MULTI-FUNCTION KEYPAD

 Switching the operation mode betw een remote and local

The inverter can be operated either in remote mode or in local mode. In remote mode, which applies to normal operation, the inverter is driven under the control of the data settings held in it, whereas in local mode, which applies to maintenance operation, it is separated from the system and is driven manually under the control of the keypad.

Remote mode: The sources for setting run and frequency commands is determined by various

setting means switching signals such as fun ction codes, switch ing of run command 1/2, and link priority function.

Local mode: The sources for setting run and frequency commands is the keypad, regardless of

the settings specified by function codes. The keypad takes precedence over the setting means specified by the run command 1/2 or the link priority function.

What follows shows the setting means of run command using the keypad in the local operation mode.

3-3

Table 3.2 Run Commands from the Keypad in the Local Operation Mode

If function code F02 is set to: Setting means of the run command 0: Keypad You can run/stop the motor using the / / key on the keypad. 1: External signal 2: Keypad (forward) You can run/stop the motor using the / key on the keypad.

You can run the motor in forward direction only. (The

3: Keypad (reverse) You can run/stop the motor using the / key on the keypad.

You can run the motor in reverse direction only. (The

key has been disabled.)

The source for setting run and frequency commands can be switched between Remote and Local modes by the

key on the keypad. (This key is a toggle switch: Each time you press it for more than 1 second , the

mode switches from Romote to Local or vice versa.) The mode can be switched also by an external digital input signal. To enable the switching you need to

assign (LOC) to one of the digital input terminals, which means that the commands from the keypad are given precedence (one of function codes E01 to E05, E98, or E99 m ust be se t to " 35"). By fact ory default, (LOC) is assigned to [X5].

You can confirm the current mode on the indicators (REM: Remote mode; LOC: Local mode). When the mode is switched from Remote to Local, the frequency settings in the Remote mode are

automatically inherited. Further, if the inverter is in Running mode at the time of the switching from Remote to Local, the Run command is au tomatically turned ON so t hat all the necess ary data settin gs will be carried over. If, however, there is a discrepancy between the settings on the keypad and those on the inverter itself (e.g., switching from reverse rotation in the Remote mode to forward rotation in the Local mode using the keypad that is for forward rotation only), the inverter automatically stops.

The paths of transition between Remote and Local modes depend on the current mode and the value (ON/OFF) of (LOC), the signal giving precedence to the commands from the keypad, as shown in the state transition diagram (Figure 3.5) given below.

 For further details on how to set operation commands and frequencies in Remote and Local modes,

refer to Chapter 4 "BLOCK DIAGRAMS FOR CONTROL LOGIC" (especially Section 4.3 “Drive Command Generator” block diagram).

 Hexadecimal expression

Each I/O terminal is assigned to one of the 16 binary bits (bit 0 through bit 15). The bit to which no I/O terminal is assigned is considered to have a value of "0." The I/O signa ls are thus collectively expre ssed as a hexadecimal number (0 through F).

In the FRENIC-Eco Series, digital input terminals [FWD] and [[REV] are assigned to bits 0 and 1, and [X1] through [X5] to bits 2 through 6, respectively. Each bit assumes a value of "1" when the corresponding signal is ON and a value of "0" when it is OFF

(Note)

. For example, when signals [FWD] and

[X1] are ON while all the other signals are OFF, the status is expressed as "0005H."

(Note) The ON/OFF state of each signal at terminals [FWD], [REV], and X1 through [X5] is to be interpreted according

to the states of the source/sink switch as shown in Chapter 8, Section 8.3.1 "Terminal functions."

Digital output terminals [Y1] through [Y3] are assigned to bits 0 through 2. Each is given a val ue of "1" when it is short-circuited to [CMY], or a value of "0" when its circuit to [CMY] is open. The s tatus of relay output terminal [Y5A/C] is assigned to bit 4, which assumes a value of "1" when the contact between [Y5A] and [Y5C] is closed. The status of relay output terminal [30A/B/C] is assigned to bit 8, which assumes a value of "1" when the contact between [30A] and [30C] is closed or "0" when the contact between [30B] and [30C] is closed. For example, when term inal [Y1] is O N, term inals [Y2] and [Y3]] ar e OFF, the contact between [Y5A] and [Y5C] is opened, and the link between 30A and 30C is closed, the status is expressed as "0101H."

(Note 1) The factory default setting is “Run forward” by using the

key on the keypad. To tune the motor parameters in

“Run reverse”, change data of the function code F02.

(Note 2) • Time needed for tuning while the motor is stopped (P04 = 1) will be less than 40 seconds.

• In tuning while the motor is running (P04 = 2), the inverter accelerates th e motor u p to around 50% of the base frequency, starts tuning of motor parameters, and decelerates to stop the motor after the end of tuning. Estimated time needed for tuning in this case will be (acceleration time + 10 + deceleration time) seconds.

4.1 Symbols Used in the Block Diagrams and their Meanings

FRENIC-Eco series of inverters for variable torque loads increasing in prop orti on t o the sq uare of speed such as fans and pumps are equipped with a number of function codes to m atch a vari ety of m otor operations req uired in your system. Refer to Chapter 9 "FUNCTION CODES" for details of the function codes.

The function codes have functional relationship each other. Several special function codes also work with execution priority each other depending on their functions or data settings.

This chapter explains the main block diagrams for control logic in the inverter. You are requested to fully understand the inverter's control logic together with the function codes in order to set the function code data correctly.

The block diagrams contained in this chapter show only function codes having mutual relationship. For the function codes that work independently and for detailed explanation of each function code, refer to Chapter 9 "FUNCTION CODES."

4.1 Symbols Used in Block Diagrams and their Meanings

Table 4.1 lists symbols commonly used in block diagrams and their meanings with some examples.

Digital inputs/outputs to/from the inverter's control terminal block.

Terminal commands assigned to digital inputs/ outputs.

Low-pass filter: Features appropriate characteristics by changing the time constant through the function code data.

Internal control command for inverter logic.

High limiter: Limits the upper value by a constant or data set to a function code.

Low limiter: Limits the lower value by a constant or data set to a function code.

Zero limiter: Prevents data from dropping to a negative value.

Gain multiplier for reference frequencies given by current and/or voltage input or for analog output signals.

C = A × B Adder for 2 signals or values. C

= A + B If B is negative then C = A – B

(acting as a subtracter).

Function code.

Switch controlled by a function code. Numbers assigned to the terminals express the function code data.

Switch controlled by a terminal command. In the example shown on the left, the enable communications link command (LE) assigned to one of the digital input terminals from [X1] to [X5] controls the switch.

OR logic: In normal logic, if any input is ON, then C = ON. Only if all inputs are OFF, then C = OFF.

NOR (Not-OR) logic: In normal logic, if any input is OFF, then C = ON. If all inputs are ON, C = OFF.

AND logic: In normal logic, only if A = ON and B = ON, then C = ON. Otherwise, C = OFF.

NOT logic: In normal logic, if A = ON , then B = OFF, and vice versa.

4.2 Drive Frequency Command Generator

Figure 4.1 shows the processes that generate the internal drive frequency command through the various frequency command and switching steps by means of function codes. If PID process control takes effect (J01=1 or 2), the drive frequency command generator will differ from that shown in this diagram. (Refer to Section 4.8 "PID Frequency Command Generator.")

Additional and supplemental information is given below.

• Frequency command sources using the

key on the keypad may take different formats such as motor

speed in r/min, load shaft speed in r/m in or speed in % by m eans of the da ta setup of function c ode E48. Refer to the function code E48 in Chapter 9 "FUNCTION CODES" for details.

• If the voltage input terminal [V2] is spec ified to t he PTC therm istor input (i.e. setting the sli de switch SW5 o n the control printed circuit board (control P CB) to th e PT C side an d set up of fun ction code H 26 d ata at 1 or 2), then the frequency command input signal on the terminal [V2] will always be interpreted as "0."

• Case that data setup for both the gain and bias will take effect concurrently is only ava ila ble for the f reque ncy command source 1 (F01). For the frequency command source 2 (C30) and auxiliary frequency command sources 1 and 2 (E61 to E63), only setup of the gain will take effect.

• Switching between normal and inverse operation is only effective for the reference fr equency from the ana log frequency command input signal (term inal [12], [C1] or [V2]). Note that the frequency command source set up by using the

key is only valid for normal operation.

• Frequency commands by S01 and S05 for the communicati ons link facility tak e different command form ats as follows.

- S01: the setting range is –32768 to +32767, where the maximum frequency is obtained at ±20000

- S05: the setting range is 0.00 to 655.35 Hz in increments of 0.01 Hz

- Basically, priority level for the command in S01 is higher than that in S05. If a value other than "0" is set in S01, the data set in S01 will take effect. If S01 is set at "0", data in S05 will take effect.

- Refer to the RS-485 Communication User’s Manual for details.

• The frequency limiter (Low) (F16) helps user select the inverter operation for either the output frequency is held at data of the frequency limiter (lower), or the inverter decelerates to stop the motor with reference frequency data of "0", by specifying the lower limiter (select) (H63.)
