Chapter 1 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 result in serious consequences. These safety precautions are of utmost importance and must be observed at all times.

Application

• The FRENIC-Ace is designed to drive a three-phase induction motor. Do not use it for single-phase motors or for other purposes.

Fire or an accident could occur.

• The FRENIC-Ace may not be used for a life-support system or other purposes directly related to the human safety.

• Though the FRENIC-Ace is manufactured under strict quality control, install safety devices for applications where serious accidents or property damages are foreseen in relation to the failure of it.

An accident could occur.

Installation

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

Otherwise, a fire could occur.

• Do not place flammable object nearby.

Doing so could cause fire.

• Inverters FRN0085E2■-4G or above, whose protective structure is IP00, involve a possibility that a human body may touch the live conductors of the main circuit terminal block. Inverters to which an optional DC reactor is connected also involve the same. Install such inverters in an inaccessible place.

Otherwise, electric shock or injuries could occur.

• Do not support the inverter by its front cover during transportation.

Doing so could cause a drop of the inverter and injuries.

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

• When changing the positions of the top and bottom mounting bases, use only the specified screws.

Otherwise, a fire or an accident might result.

• Do not install or operate an inverter that is damaged or lacking parts.

Doing so could cause fire, an accident or injuries.

1-2

Wiring

• If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is installed in the upstream power supply line, in order to avoid the entire power supply system's shutdown undesirable to factory operation, install a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) individually to inverters to break the individual inverter power supply lines only.

Otherwise, a fire could occur.

• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of each pair of power lines to inverters. Use the recommended devices within the recommended current capacity.

• Use wires in the specified size.

• Tighten terminals with specified torque.

Otherwise, a fire could occur.

• When there is more than one combination of an inverter and motor, do not use a multicore cable for the purpose of handling their wirings together.

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

Doing so could cause a fire.

• Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds 500 kVA and is 10 times or more the inverter rated capacity.

Otherwise, a fire could occur.

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

• Be sure to ground the inverter's grounding terminals G.

Otherwise, an electric shock or a fire could occur.

• Qualified electricians should carry out wiring.

• Be sure to perform wiring after turning the power OFF.

Otherwise, an electric shock could occur.

• Be sure to perform wiring after installing the inverter unit.

Otherwise, an electric shock or injuries could occur.

• Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage of the AC power supply to which the product is to be connected.

Otherwise, a fire or an accident could occur.

• Do not connect the power supply wires to output terminals (U, V, and W).

• When connecting a DC braking resistor (DBR), never connect it to terminals other than terminals P(+) and DB.

Doing so could cause fire or an accident.

• In general, sheaths of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath might break down, which would expose the signal wire to a high voltage of the main circuit. Make sure that the control signal wires will not come into contact with live conductors of the main circuit.

Doing so could cause an accident or an electric shock.

• Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and

wait at least five minutes for inverters FRN0115E2■-2G / FRN0072E2■-4G or below, or at least ten minutes for inverters FRN0085E2■-4G or above. Make sure that the LED monitor and charging lamp are

turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).

Otherwise, an electric shock could occur.

• The inverter, motor and wiring generate electric noise. Be careful about malfunction of the nearby sensors and devices. To prevent them from malfunctioning, implement noise control measures.

Otherwise an accident could occur.

1-3

Operation

• Be sure to mount the front cover before turning the power ON. Do not remove the cover when the inverter power is ON.

Otherwise, an electric shock could occur.

• Do not operate switches with wet hands.

Doing so could cause electric shock.

• If the auto-reset 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 at the time of restarting.

Otherwise, an accident could occur.

• If the stall prevention function (current limiter), automatic deceleration (anti-regenerative control), or overload prevention control has been selected, the inverter may operate with acceleration/deceleration or frequency different from the commanded ones. Design the machine so that safety is ensured even in such cases.

• The key on the keypad is effective only when the keypad operation is enabled with function code F02 (= 0, 2 or 3). When the keypad operation is disabled, prepare an emergency stop switch separately for safe operations.

Switching the run command source from keypad (local) to external equipment (remote) by turning ON the

"Enable communications link" command LE disables the key. To enable the key for an emergency stop, select the STOP key priority with function code H96 (= 1 or 3).

• If any of the protective functions have been activated, first remove the cause. Then, after checking that the all run commands are set to OFF, release the alarm. If the alarm is released while any run commands are set to ON, the inverter may supply the power to the motor, running the motor.

Otherwise, an accident could occur.

• If you enable the "Restart mode after momentary power failure" (Function code F14 = 3 to 5), then the inverter automatically restarts running the motor when the power is recovered.

Design the machinery or equipment so that human safety is ensured after restarting.

• If the user configures the function codes wrongly without completely understanding this User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.

• Starting auto-tuning involves motor rotation. Sufficiently check that motor rotation brings no danger beforehand.

An accident or injuries could occur.

• Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input terminals L1/R, L2/S, L3/T, L1/L and L2/N, voltage may be output to inverter output terminals U, V, and W.

• Even if the motor is stopped due to DC braking or preliminary excitation, voltage is output to inverter output terminals U, V, and W.

An electric shock may occur.

• The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the specifications of motors or equipment beforehand.

Otherwise, injuries could occur.

• Do not touch the heat sink and braking resistor because they become very hot.

Doing so could cause burns.

• The DC brake function of the inverter does not provide any holding mechanism.

Injuries could occur.

• Ensure safety before modifying the function code settings.

Run commands (e.g., "Run forward" FWD), stop commands (e.g., "Coast to a stop" BX), and frequency

change commands can be assigned to digital input terminals. Depending upon the assignment states of those terminals, modifying the function code setting may cause a sudden motor start or an abrupt change in speed.

• When the inverter is controlled with the digital input signals, switching run or frequency command sources with the related terminal commands (e.g., SS1, SS2, SS4, SS8, Hz2/Hz1, Hz/PID, IVS, and LE) may cause a sudden motor start or an abrupt change in speed.

• Ensure safety before modifying customizable logic related function code settings (U codes and related function codes) or turning ON the "Cancel customizable logic" terminal command CLC. Depending upon the settings, such modification or cancellation of the customizable logic may change the operation sequence to cause a sudden motor start or an unexpected motor operation.

An accident or injuries could occur.

1-4

Maintenance and inspection, and parts replacement

• Before proceeding to the maintenance/inspection jobs, turn OFF the power and wait at least five minutes for inverters FRN0115E2■-2G / FRN0072E2■-4G or below, or at least ten minutes for inverters FRN0085E2■-4G or above. Make sure that the LED monitor and charging lamp are turned OFF. Further,

make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).

Otherwise, an electric shock could occur.

• Maintenance, inspection, and parts replacement should be made only by qualified persons.

• Take off the watch, rings and other metallic objects before starting work.

• Use insulated tools.

Otherwise, an electric shock or injuries could occur.

• Never modify the inverter.

Doing so could cause an electric shock or injuries.

Disposal

• Treat the inverter as an industrial waste when disposing of it.

Otherwise injuries could occur.

able 2.2-1 Input control signals to the inverter.

INPUT DESCRIPTION SYMBOL

[12]

Water tank level analog signal. The signal from the water level sensor of the tank can be connected to this input. The inverter will stop when the tank level becomes higher than the level programmed in parameter U128. In order to use this signal, connect the sensor to this input and set the desired tank level above which the pump has to stop. If this signal is not used, set a high level in parameter U128 to avoid that the inverter stops.

TANK LEVEL

[FWD] Run command in the FWD direction FWD

[REV] Run command in the REV direction REV

[X1]

Water tank high level digital signal. This signal is ON when the level of the tank is high. The inverter will stop when this signal is ON. In order to use this signal, simply connect it to the inverter; it is not required to enable it by function code.

TANK HL

able 2.2-2 describes the outp ut control signals f rom the inverter. The assignment of the out puts can

be changed if required. To do so, change the settings of parameters E20, E21, E27.

able 2.2-2 Output control signals from the inverter.

OUTPUT DESCRIPTION SYMBOL

[Y1]

Tank full output signal. This signal indicates that the water tank is full. In this situation the inverter will not be allowed to RUN, therefore this signal is useful to indicate/diagnose the cause of the stop.

TANK FULL

[Y2]

Low power output signal. This signal indicates that the output power is low. In case that this signal is ON and the solar irradiance is high, it is useful to detect/diagnose that there is a problem in the PV solar panel (for example dust, or the panel has been covered).

LOW POWER

[30A/B/C]

This relay output is used to indicate that the inverter has tripped by alarm. The alarm code is displayed in the inverter keypad.

ALM

2.2.2 Inverter supplied from PV panel only

There are two alternatives of connecting the PV panel to the inverter:

(1) Connected to the DC bus terminals P(+), N(-). I n this case the pre charging ci rcuit of the inve rter is not

used. Therefore, when the PV panel is connected to the inverter, high current may flow through at the initial stage because the inverter DC link capacitor is discharged. In order to avoid the high charging current, there are some alternatives:

o do not make the connection when the PV panel is already receiving strong irradiat ion, or o insert a pre-charging circuit in the connection between (+) (PV panel positive pole) and P(+), or o use the connection alternative (2) described in following pages.

When using this wiring please ensure that the motor is not regenerating. In case of regeneration the DC link voltage of the inverter will rise damaging the PV panels. In order to avoid regeneration when operation command is removed please set function code H11=1 (Coast to a stop). If regeneration cannot be avoided (for example, controlled deceleration is always required), please use connection alternative (2) below.

(2) Connected to the AC supp ly input s and N(-). In this case the precharging circuit of the inverter is used,

limiting the initial charging current of the inverter DC link capacitor. In this case be aware that the maximum frequency of charging cycles is two times per hour. When using this connection the current rating of the input rectifier must be considered. Please consult Fuji Electric to make the inverter selection.

• The PV panel is a DC voltage/current source. Therefore in all cases please ensure that the polarity is respected when performing the connection between the inverter and the PV panel, otherwise either equipment may be damaged

Risk of fire and risk of damage exist.

Notes for all drawings:

(Note 1) Install recommended circuit breakers (MCCB) or residual-current-operated protective device (RCD)/

earth leakage breakers (ELCB) (with overcurrent protective function) on the inputs of each inverter (primary side) for wiring protection. Do not use breakers which exceed the recommended rated current

(Note 2) Install recommended magnetic contactors (MC) as necessary on each inverter as these will be used to

disconnect the inverter from the power supply separately from the MCCB or the RCD / ELCB. Additionally, when installing coils such as MC or solenoid close to the inverter, connect surge absorbers in parallel.

(Note 3) Make the necessary interlock to avoid that both PV panel supply and AC supply are connected at the

same time. Not preventing this may cause damage to the equipment.

(Note 4) Used for the protection of the PV panel and the wiring. Alternatively fuses can be also used. Please

use recommended types by the PV panel maker. The use of additional protection devices (like surge protection devices) may be also recommended by the PV panel maker.

(Note 5) Use this terminal when supplying the inverter with DC voltage from the PV panel. Applicable for types

FRN0203E2■-4G or above. Please consult Fuji Electric.

(Note 6) Remove the shorting bar between the inverter main circuit terminals P1-P(+) before connecting the

direct current reactor (DCR) (option). It must be connected in the following cases: ND mode: T y pes FRN0139 E2■-4G or above, HD/ HND mode: T y pes FRN01 68E2■-4G or above, HHD mode: Types FRN0203E2■-4G or above. Use the direct current reactor (option) when the power supply transformer capacity is above 500 kVA and the transformer capacity is over 10 times the rated capacity of the inverter, or when “thyristor load exists” in the same power system. In case of PV panel supply only, DCR is not required for any capacity.

(Note 8) This terminal is used for grounding the motor. Grounding the motor using this terminal is recommended

in order to suppress inverter noise.

(Note 9) Use twisted lines or shielded lines for the control signals.

Generally, the shielded line requires grounding, but when the effect of externally induced noise is large, connecting to [CM] may suppress the eff ect of noise. Separate the line from the main circuit wiring and do not enclose in the same duct. Separation distance of over 10 cm is recommended. When crossing the main circuit wiring, make the intersection perpendicular.

(Note 10) The various functions listed for terminals [X1] to [X5] (digital inputs), terminals [Y1] to [Y2] (transistor

outputs), and terminal [FM] (monitor output) show the recommended functions for Solar Pumping application.

(Note 11) These are conne ctors for switching the main circuit. For details, refer to “2.2.7 Switching connectors”.

(Note 12) The various switches on the control printed circuit board define the settings for the inverter operation.

For details, refer to “2.2.6 Operating slide switches”.

(Note 14) Shorting bars are connected between the safety function terminals [EN1], [EN2], and [PLC] as factory

default. Remove the shorting bars when using this function.

RUN LED

Lights when running with a run command entered by the

key, by terminal

command FWD or REV, or through the communications link.

KEYPAD CONTROL LED

Lights when the inverter is ready to run with a run command entered by the key

(F02 = 0, 2, or 3). In Programming and Alarm modes, however, pressing the key cannot run the inverter even if this indicator lights.

Unit LEDs (3 LEDs)

These three LED indicators identify the unit of numeral displayed on the LED monitor in Running mode by combination of lit and unlit states of them. Unit: Hz, A, kW, r/min and m/min

Refer to Section ¡Error! No se encuentra el origen de la referencia. "¡Error! No se encuentra el origen de la referencia." for details.

While the inverter is in Programming mode, Hz the LEDs of Hz and kW light. A

kW

x10 LED

Lights when the data to display exceeds 9999. When this LED lights, the "displayed value x 10" is the actual value.

Example: If data is "12,345," the LED monitor displays

1234

and the x10 LED lights, meaning

that "1,234 × 10 = 12,340."

 LED monitor

In Running mode, the LED monitor displays running status information (output frequency, current or voltage); in Programming mode, it displays menus, function codes and their data; and in Alarm mode, it displays an alarm code which identifies the alarm factor that has activated the protective function.

If one of LED4 through LED1 is blinking, it means that the cursor is at this digit, allowing you to change it.

If the decimal point of LED1 is blinking, it means that the currently displayed data is a value of the PID command, not the frequency data usually displayed.

3.2 Overview of Operation Modes

The FRENIC-Ace features the following three operation modes.

Table 3.2-1 Operation Modes

Operation mode

Description

Running mode

When powered ON, the inverter automatically enters this mode.

This mode allows you to specify the reference frequency, PID command value and etc., and run/stop the motor with the / keys.

It is also possible to monitor the running status in real time.

If a light alarm occurs, the

l-al

appears on the LED monitor.

Programming mode

This mode allows you to configure function code data and check a variety of information relating to the inverter status and maintenance.

Alarm mode

If an alarm condition arises, the inverter automatically enters Alarm mode in which you can view the corresponding alarm code* and its related information on the LED monitor.

* Alarm code: Indicates the cause of the alarm condition. For details, first see Table 6.1

"Abnormal States Detectable ("Heavy Alarm" and "Light Alarm" Objects)" in Chapter 6, Section 6.1 "Protective Function," and then read the troubleshooting of each alarm.

Figure 3.2-1 shows the status transition of the inverter between these three operation modes.

Simultaneous keying

Simultaneous keying means pressing two keys at the same time. The simultaneous keying operation is

expressed by a "+" letter between the keys throughout this manual.

For example, the expression " + keys" stands for pressing the key with the key held down.

Figure 3.2-2 illustrates the transition of the LED monitor screen during Running mode, the transition between menu items in Programming mode, and the transition between alarm codes at different occurrences in Alarm mode.

(*1) The speed monitor allows you to select the desired one from the speed monitor items by using function code

E48. (*2) Applicable only when PID control is active (J01 = 1, 2 or 3). (*3) The analog input monitor can appear only when the analog input monitor function is assigned to one of the

analog input terminals by one of function codes E61 to E63 (= 20). (*4)

appears under the V/f control.

(*5) The Timer screen appears only when the timer operation is enabled with function code C21 (C21 = 1). (*6) Applicable only when the full-menu mode is selected (E52 = 2).

Chapter 4 SET UP PROCEDURE

This chapter describes a simple step by step set up procedure of FRENIC-Ace for solar pumping application. Please refer to:

- chapter 2 for detailed information about installation and wiring

- chapter 3 for the information about the operation of the keypad

- chapter 5 for detailed description of the function codes.

In order to set up FRENIC-Ace for solar pumping application, please proceed with the following step by step procedure:

1. Install the inverter as described in chapter 2 of this manual.

2. Set up the motor parameters and, whenever possible, execute the auto tuning procedure. If the motor is already coupled with the load (pump) please execute static auto-tuning (P04=1). If the motor can be dismounted from the load please execute dynamic auto-tuning (P04=2), which measures more motor parameters than the static auto-tuning (for details, please refer to chapter 5). Some functions like the dry pump detection and low power detection will work with the best accuracy only if the motor parameters are correctly set.

3. Set up the parameter F02 (Operation method) to 1 (External signal).

4. Set up the parameter H11 (Deceleration mode) to 1 (Coast to a stop).

5. Set the PID control related parameters:

o J01 (Mode selection) to 2 (inverse operation) o J02 (Remote command) to 1 (PID process command 1) o J06 (Feedback filter) to 0.0s (No filter).

6. Set up the following parameters related to the PV panel specifications: o Function code U126 (PV panel open circuit voltage) is used to set the PV panel open circuit

voltage

o Function code U127 (PV panel MPP voltage) is used to set the PV panel MPP voltage

7. Set up the following parameters related to the MPP search (tracking) function: o Function code U121 (Enable MPP search) must be set to “1.00” to enable the MPP search

function

o Function code U135 (Voltage/PID set point increase/decrease step for MPP search) to set the

set point increase/decrease at each step of the MPP search function.

8. Set up the parameters related to the sleep function: o Function code J15 (Sleep frequency) to set the minimum frequency level to keep running,

because the pump is not anymore effective when rotating at lower speeds than the value set in this function code. This setting depends mainly on the pump specifications.

o Function code U134 (Power level to keep running) to set the minimum power level to keep

running. If the power level is very small, it means that the pump may not be effective anymore. This setting depends mainly on the pump specifications.

It is important to note that it is not compulsory to set both parameters. The inverter can use either the sleep frequency or the minimum power as the stop (sleep) criteria. In other words, it is not required to fulfill both conditions.

Do not change the value of function code J17 from factory default value, otherwise it would interfere with the sleep and wake up functions.

9. Set up the following parameters related to the wake up function: o Function code U131 (DC link voltage level to start) to set the minimum voltage level of the PV

panel (DC link) to allow the operation of the inverter. This parameter is very important to avoid that the inverter (pump) starts operation when there is not enough available power from the PV panel. The value of this parameter can be set from PV panel specification or from tests at very low irradiance conditions (for example during sunset).

Do not change the value of function code J17 from factory default value, otherwise it would interfere with the sleep and wake up functions.

4-2

10. Set up the initial parameters of the PID regulator: o PID controller gains J59 (P Gain 2) and J60 (I integral time 2), used when the PID feedback

value is higher than the PID set point value. As initial values set the values recommended in chapter 5.

o PID controller gains U132 (P Gain 1) and U133 (I integral time 1), used when the PID feedback

value is lower than the PID set point value. As initial values set the values recommended in chapter 5.

11. Check that the function codes related to the digital inputs [FWD] and [REV] are set to “No function assigned”.

( Function code E98, E99 data = 100)

12. If tank high level digital detection signal is used, check that the function code related to the digital input [X1] is set to “No function assigned”.

( Function code E01 data = 100)

13. If tank level analog detection signal is used, set function code U128 (High level) to the desired maximum level of the tank. If this signal is not used, set function code U128 to 100%, to ensure that the pump starts (inverter operates) regardless of the value on the analog input of the inverter.

14. Ensure that function code U00 (Mode Selection) is set to 1, in order to enable the Solar Pumping application.

• When setting U00 to 1 the operation of the inverter may start (if all necessary conditions are fulfilled). Please ensure that it is safe to start operation.

An accident or physical injury may result.

5.2 Description of Function Codes

This section describes details of function codes relevant for Solar Pumping application.

F02

Operation method

Related function codes: Terminal E98 [FWD] function

Terminal E99 [REV] function

F02 is used to select the method how run command is provided to the inverter. In case of Solar pumping application please set F02 to 1, so that the operation command can be given from Customized Logic program.

Digital input signal, "FWD", "REV" should not be assigned to terminals [FWD], [REV], therefore please assign the function of these terminals to “No function”. ( Function code E98, E99 data = 100)

• F02 cannot be changed when "FWD" or "REV" is ON.

F03

Maximum frequency 1

F03 specifies the maximum frequency that the inverter outputs. When the device to be driven is set to rated or higher, the device may be damaged. Make sure to make an adjustment according to the design of the machinery.

• Data setting range: 25.0 to 500.0 (Hz)

Restricted internally.*

* When setting is performed by exceeding the maximum setting range (for example, 500 Hz), speed setting and

analog output (FMA) become input/output mode of full scale/setting value (10V/ 500Hz). However, it is internally restricted (for example, 120Hz), therefore, even if 10V is input for setting value, the value is restricted internally by 2.4 V (equivalent to 120 Hz), not by 500Hz.

Use function code F80 to switch between ND, HD, HND and HHD drive modes.

Inverter can perform setting of high speed operation easily. When changing the setting, make sure to check the motor and machine mode before use.

Injuries could occur. Failure may occur.

When changing maximum output frequency (F03), in order to make the operation frequency a larger value, change the frequency limiter (upper limit) (F15) as well.

By combining related function codes H50 to H53, H65, and H66, it is possible to set non-linear V/f pattern (weak or strong voltage by arbitrary point) and perform setting of V/f characteristics that is suitable for the load.

Impedance of the motor becomes larger with high frequency, and when output voltage becomes less, output torque may be reduced. In order to prevent this, increase the voltage at high frequency by setting function code F06 (maximum output voltage 1). However, it is not possible to output voltage at or higher than the input power voltage of the inverter.

• When data is set to "0", the base frequency voltage becomes equivalent to inverter input voltage. When input voltage fluctuates, output voltage fluctuates as well.

• When data is set to arbitrary voltage other than "0", automatically keeps the output voltage constant. When control function such as auto torque boost, auto energy-saving operation, and skip compensation is used, it is necessary to adjust to the rated voltage (given on the nameplate of the motor) of the motor.

The voltage that the inverter can output is lower than the input voltage of the inverter. Appropriately set the voltage in accordance with the motor.

In order to detect overload of motor (electronic thermal function by inverter output current), set temperature characteristics of motor: Select motor characteristics (F10), thermal time constant (F12), and overload detection level (F11).

When overload of motor is detected, inverter is turned off, protecting the motor with motor overload alarm 0l1.

Improper setting of the electronic thermal function may result in a failure to protect the motor from burning.

Temperature characteristics of motor is used for motor overload early warning "OL" as well. Even if only overload early warning is used, it is necessary to set temperature characteristics of the motor (F10, F12). ( Function code E34)

For disabling motor overload alarm, set F11 = 0.00 (Disable).

For PTC thermistor built-in motor, by connecting PTC thermistor to terminal [C1], it is possible to protect the motor. Refer to H26 to find the details.

When F10=2 is set, cooling effect by output frequency will not decrease, therefore, overload detection level becomes constant value (F11) without decrease.

 Overload detection level (F11)

F11 sets operation level of electronic thermal.

• Data setting range: 1 to 135% of the rated current value of inverter (continuous allowance current value) Normally, set to the motor continuous allowance current (in general, about 1.0 to 1.1 times of motor rated current)

when operating at base frequency. For disabling electronic thermal, set F11 = 0.00: Disable.

 Thermal time constant (F12)

F12 sets thermal time constant of the motor. For overload detection level that is set by F11, set the electronic thermal operation time when 150% of current is flowing continuously. Thermal time constant of general-purpose motor of Fuji Electric and general motors is 5 minutes for 22 kW or lower, and 10 minutes (factory default state) for 30kW or higher.

• Data setting range: 0.5 to 75.0 (min) (Example) When the data of function code F12 is set to "5" (5 minutes). As shown in the diagram below, when 150% of current of operation level that was set flows for 5 minutes, motor

overload (alarm 0l1) protection function will operate. In addition, with 120%, it operates after 12.5 minutes. The time when alarm actually occurs is shorter than the set data because the time until the current reaches 150%

level after exceeding the continuous allowance current (100%) is considered. <Example of current-operation time characteristics>

frequency

When momentary power failure occurs while operating the inverter, and at the time when undervoltage is detected by the DC link bus voltage of the inverter, the inverter output shuts down, and the motor coasts to a stop.

If run command is entered at auto-restarting, restart from the starting frequency that was set by function code F23.

If run command is entered at auto-restarting, auto-searching is performed, motor speed is estimated, and restart from the frequency.

This setting is most suitable for the case (pump etc.) when load inertia moment is small, when the load is heavy, and motor speed decreases up to 0 in a short time after the motor coasts to a stop due to momentary power failure.

When momentary power failure restart operation (F14 = 3 to 5) is selected, operation will resume automatically at auto-restarting. Design your machinery so that safety is ensured even at restarting.

Otherwise an accident could occur.

If a required "load torque + acceleration toque" is 50% or more of the rated torque, it is recommended to select the linear V/f pattern. Factory defaults are set to linear V/f pattern.

 V/f characteristics

The FRENIC-Ace series of inverters offer a variety of V/f patterns and torque boosts, which include V/f patterns suitable for variable torque load such as general fans and pumps and for constant torque load (including special pumps requiring high starting torque). Two types of torque boosts are available: manual and automatic.

Variable torque V/f pattern (F37 = 0)

Linear V/f pattern (F37 = 1)

When the variable torque V/f pattern is selected (F37 = 0 or 3), the output voltage may be low at a low frequency zone, resulting in insufficient output torque, depending on the characteristics of the motor and load. In such a case, it is recommended to increase the output voltage at the low frequency zone using the non-linear V/f pattern.

 Torque boost

• Manual torque boost by F09 (Manual adjustment)

• Data setting range: 0.0 to 20.0 (%), (100%/base frequency voltage) In torque boost using F09, constant voltage is added to the basic V/f pattern, regardless of the load. To secure a

sufficient starting torque, manually adjust the output voltage to optimally match the motor and its load by using F09. Specify an appropriate level that guarantees smooth startup and yet does not cause over-excitation at no or light load. Torque boost using F09 ensures high driving stability since the output voltage remains constant regardless of the load fluctuation. Specify the function code F09 data in percentage to the base frequency voltage. At factory shipment, boost amount with which approx. 100% of starting torque can be assured, is specified.

• Specifying a high torque boost level will generate a high torque, but may cause overcurrent due to over-excitation at no load. If you continue to drive the motor, it may overheat. To avoid such a situation, adjust torque boost to an appropriate level.

• When the non-linear V/f pattern and the torque boost are used together, the torque boost takes effect below the frequency on the non-linear V/f pattern’s point.

• Auto torque boost

This function automatically optimizes the output voltage to fit the motor with its load. Under light load, auto torque boost decreases the output voltage to prevent the motor from over-excitation. Under heavy load, it increases the output voltage to increase the output torque of the motor.

• This function controls in accordance with motor characteristics. Therefore, set the base frequency 1 (F04), rated voltage at base frequency 1 (F05), and other pertinent motor parameters (P01 through P03 and P06 through P99) in line with the motor capacity and characteristics, or else perform auto-tuning (P04).

• When a special motor is driven or the load does not have sufficient rigidity, the maximum torque might decrease or the motor operation might become unstable. In such cases, do not use auto torque boost but choose manual torque boost using F09 (F37 = 0 or 1).

 V/f control without slip compensation

Under this control, the inverter controls a motor with the voltage and frequency according to the V/f pattern specified by function codes. This control disables all automatically controlled features such as the slip compensation, so no unpredictable output fluctuation occurs, enabling stable operation with constant output frequency.

 V/f control with slip compensation

Applying any load to an induction motor causes a rotational slip due to the motor characteristics, decreasing the

motor rotation. The inverter’s slip compensation function first presumes the slip value of the motor based on the

motor torque generated and raises the output frequency to compensate for the decrease in motor rotation. This prevents the motor from decreasing the rotation due to the slip.

That is, this function is effective for improving the motor speed control accuracy.

 Vector control without speed sensor (dynamic torque vector)

To get the maximal torque out of a motor, this control calculates the motor torque matched to the load applied and uses it to optimize the voltage and current vector output.

When the vector control without speed sensor (dynamic torque vector) is selected, automatically auto torque boost and slip compensation become enabled. This control is effective for improving the system response to external disturbances such as load fluctuations, and the motor speed control accuracy.

Note that the inverter may not respond to a rapid load fluctuation.

For slip compensation in case of vector control without speed sensor, constants of motor are used. Therefore, satisfy the following conditions below. If these conditions cannot be satisfied, sufficient control performance may not be obtained.

• A single motor is controlled per inverter.

• The prerequisite is that motor parameter P02, P03, P06 to P13 are accurately set or auto-tuning is

performed.

• Under vector control without speed sensor, the capacity of the motor to be controlled must be not less than two ranks lower of the inverter capacity. Otherwise, the inverter may not control the motor due to decrease of the current detection resolution.

 V/f control with speed sensor

Applying any load to an induction motor causes a rotational slip due to the motor characteristics, decreasing the motor rotation. Under V/f control with speed sensor, the inverter detects the motor rotation using the encoder mounted on the motor shaft and compensates for the decrease in slip frequency by the PI control to match the motor rotation with the reference speed. This improves the motor speed control accuracy.

 V/f control with speed sensor and auto torque boost

The difference from "V/f control with speed sensor" stated above is to calculate the motor torque that matches to the load applied, and use it to optimize the voltage and current vector output for getting the maximal torque from the motor.

This control is effective for improving the system response to external disturbances such as load fluctuations, and the motor speed control accuracy.

 Vector control for synchronous motor without speed sensor nor pole position sensor

This control estimates the motor speed based on the inverter's output voltage and current, and uses the estimated speed for speed control. It also decomposes the motor drive current into the exciting and torque current components, and controls each of those components as vectors. No PG (pulse generator) interface card is required. It is possible to obtain the desired response by adjusting the control constants (PI constants) using the speed regulator (PI controller).

When changing function code F42 to data 15 " Vector control for synchronous motor without speed sensor nor pole position sensor " by the keypad, then the inverter automatically updates data of F03, F04, F05 and others.

Depending on the state of digital input terminals, modifying a single function code setting may cause abrupt start of operation or significant change of the speed. Ensure safety before modifying the function code settings.

An accident or physical injury may result.

Terminals [Y1] function to [Y2] function Terminal [30A/B/C] function (Relay output)

E20 through E21 and E27 assign output signals to general-purpose, programmable output terminals, [Y1], [Y2] and [30A/B/C]. These function codes can also switch the logic system between normal and negative to define how the inverter interprets the ON or OFF state of each terminal. The factory default setting is normal logic system "Active ON”.

Terminals [Y1] and [Y2] are transistor outputs and terminals [30A/B/C] are contact outputs. In normal logic, if an alarm occurs, the relay will be energized so that [30A] and [30C] will be closed, and [30B] and [30C] opened. In negative logic, the relay will be de-energized so that [30A] and [30C] will be opened, and [30B] and [30C] closed. This may be useful for the implementation of failsafe power systems.

For details on these functions refer to FRENIC Ace User Manual.

• When negative logic is employed, all output signals are active (e.g. an alarm would be recognized) while the inverter is powered OFF. To avoid causing system malfunctions by this, interlock these signals to keep them ON using an external power supply. Furthermore, the validity of these output signals is not guaranteed for approximately 1.5 seconds (for 22 kW or below) or 3 seconds (for 30 kW or above) after power-ON, so introduce such a mechanism that masks them during the transient period.

• Terminals [30A/B/C] use mechanical contacts. They cannot stand frequent ON/OFF switching. Where frequent ON/OFF switching is anticipated use transistor outputs [Y1] and [Y2] instead.

 For details of auto-tuning, refer to the FRENIC-Ace Instruction Manual, Chapter 4 " TEST RUN

PROCEDURE."

In any of the following cases, perform auto-tuning since the motor parameters are different from those of Fuji standard motors so that the best performance cannot be obtained under some conditions.

• The motor to be driven is a non-Fuji motor or a non-standard motor.

• Cabling between the motor and the inverter is long (Generally, 20 m (66 ft) or longer).

• A reactor is inserted between the motor and the inverter.

H06 Cooling fan ON/OFF control

To prolong the service life of the cooling fan and reduce fan noise during running, the cooling fan stops when the temperature inside the inverter drops below a certain level while the inverter stops. However, since frequent switching of the cooling fan shortens its service life, the cooling fan keeps running for at least 10 minutes once started.

H06 specifies whether to keep running the cooling fan all the time or to enable ON/OFF control.

With the cooling fan ON/OFF control enabled (H06 = 1), this output signal is ON when the cooling fan is in operation, and OFF when it is stopped. This signal can be used to make the cooling system of peripheral equipment interlocked for an ON/OFF control

H11 Deceleration mode

H11 specifies the deceleration mode to be applied when a run command is turned OFF.

H11 data

Action

Normal deceleration

The inverter immediately shuts down its output, so the motor stops according to the inertia of the motor and machinery (load) and their kinetic energy losses. Use this setting to avoid regeneration when operation command is turned OFF.

When reducing the reference frequency, the inverter decelerates the motor according to the deceleration commands even if H11 = 1 (Coast to a stop).

H72 Main power shutdown detection (Mode selection)

This function monitors the AC input power supply of the inverter to see if the AC input power supply (main circuit power) is established and prevents inverter operation when the main circuit power is not established.

Enables main circuit power cutoff detection

With power supply directly on the DC bus there is no AC input. When the data for H72 is "1," the inverter cannot operate. Change the data for H72 to "0”. It is not required to set this parameter for models up to/including FRN0056E2S-2, and for models up to/including FRN0037E2S-4.

For single-phase supply, consult your Fuji Electric representatives.

J01

PID Control (Mode selection)

J01 is used to activate the PID control of the inverter. In case of Solar Pumping application please set this function code to 2 (inverse operation). The reason is that in this application when the PID feedback value is higher than the PID set point value the output of the PID controller has to increase the manipulated value (inverter frequency set point) in order to increase the power consumption of the motor, causing a reduction of the PV panel voltage (PID feedback).

J02

PID Control (Remote command)

This parameter is used to set the source of the set point value (SV) under PID control. For Solar Pumping application please set to 1, so that the set point value can be given from the Customized Logic program.

J06

PID Control (Feedback filter)

J06 specifies the time constant of the filter for feedback signals under PID control. In case of Solar Pumping application the recommended value is 0.0 (s). The reason is that the PID feedback value (DC link voltage/PV panel voltage) should not be filtered to be able to respond rapidly to changes on the PV panel conditions (especially irradiance when changing from cloudy to sunny and opposite).

J59 J60

PID Control (P (Gain) 2) PID Control (I (Integral time) 2)

The inverter is able to select between two PID gain sets depending on the relative values of the PID feedback and PID set point. J59 (P Gain 2) and J60 (Integral time 2) are used to set respectively the proportional gain and integral time of the PID controller when the PID feedback value is higher than the PID set point value. These constants should be set to achieve a slow response of the PID controller in order to avoid that the power drawn from the PV panel is too high when the manipulated value (inverter set point frequency) increases.

U132 U133

PID Control (P (Gain) 1) PID Control (I (Integral time) 1)

The inverter is able to select between two PID gain sets depending on the relative values of the PID feedback and PID set point. U132 (P Gain 1) and U133 (Integral time 1) are used to set respectively the proportional gain and integral time of the PID controller when the PID feedback value is lower than the PID set point value. These constants should be set to achieve a fast response of the PID controller in order to reduce as fast as possible the power drawn from the PV panel.

U128 UA14 UA18 UA23

Tank level detection function (High level) Tank level detection function (High level hysteresis width) Tank level detection function (Signal ON Delay Time) Tank level detection function (Signal OFF Delay Time)

The inverter can monitor the tank level by an analog signal from an analog sensor connected to terminal 12. The inverter can also detect the tank high level by connecting the signal from a sensor to digital input [X1]. It is possible to use either analog or digital sensor, but not both at the same time. In case of using the analog sensor, if the detected level is higher than the value set in U128 (High level) for a time longer than the time set in UA19 (Signal ON delay time) then the inverter will stop operation, in order to prevent the tank overflow. Also the inverter will activate a digital output programmed to function CL01 (TANK FULL; E20, E21 data = 111). If the detected level is lower than the value U128 – UA15 (High level hysteresis width) for a time longer than the time set in UA24 (Signal OFF delay time) then the inverter will resume operation, and will deactivate the above mentioned digital function. In case of connecting the tank high level sensor to digital input [X1], the parameters UA19 (Signal ON delay time) and UA24 (Signal OFF delay time) also apply.

5-24

Function code U128 is used to set the tank level to determine that the tank is at high level (full) and function code UA15 is used to set the hysteresis band width of U128. The units of U128 and UA15 are in percentage (%), where 100% means the maximum detectable tank level. Set U128 to 100% to disable the tank level detection by analog signal.

Function code UA19 is used to set the signal ON delay time and function code UA24 is used to set the signal OFF delay time. These delay times are helpful to filter the effects of the water waves inside the tank. The time units of UA19 and UA24 are seconds.

U130 UA48

Low power detection function (Low Power level) Low power detection function (Signal ON delay time)

The inverter monitors the output power. If the detected level is lower than the value set in U130 (Low Power level) for a time longer than the time set in UA49 (Signal ON delay time) then the inverter will activate a digital output programmed to function CL02 (LOW POWER; E20, E21 data = 112). If the detected level is higher than the value set in U130 then it will deactivate the above mentioned digital output.

Function code U130 is used to set the power level to determine the low power condition. The units of U130 are in percentage (%), where 100% means the motor rated power (value set in P02).

Function code UA49 is used to set the Low Power signal ON delay time. The time units of UA49 are seconds.

UA53 UA54 UA68 UA69 UA73 U124

Dry pump detection function (Output frequency level) Dry pump detection function (Output frequency hysteresis width) Dry pump detection function (Motor power level) Dry pump detection function (Motor power hysteresis width) Dry pump detection function (Signal ON Delay Time) Dry pump detection function (Enable Dry Pump Alarm)

The inverter monitors the output frequency and the power consumption of the motor (pump). If the output frequency is higher than the value set in parameter UA54 (Output frequency level) and the power consumed by the motor is lower than the value set in parameter UA69 (Motor power level) for a time longer than UA73 (Signal ON delay time) the inverter will determine that the pump is dry (Dry pump state); under these conditions it will activate a digital output programmed to function CL04 (DRY PUMP; E20, E21 data = 114). The inverter will determine that the pump is not anymore dry if the output frequency is below the level UA54 – UA55 (Output frequency hysteresis width) or the power consumed by the motor is higher than UA69 + UA70 (Motor power hysteresis width), and will deactivate the digital output programmed to function CL04. If function code U124 (Enable Dry Pump Alarm) is set

to “1.00” then under the dry pump conditions the inverter will stop and trip by alarm “OH2”. In the event of that the inverter has tripped by alarm “OH2”, it will stay in this condition until the alarm is reset, keeping activated the digital

output programmed to CL04; the alarm state can be reset by pressing the Reset key on the inverter keypad (on that time the digital output will be turned OFF). If the dry pump conditions continue after starting again, the inverter eventually will detect this state again.

Function code UA54 is used to set the output frequency level to detect the dry pump state and UA55 is used to set the hysteresis band width of UA54. The output frequency must be higher than the value set in UA54 to detect the dry pump state. The units of UA54 and UA55 are percentage where 100% means the maximum output frequency (value set in F03).

Function code UA69 is used to set the motor power level to detect the dry pump state and UA70 is used to set the hysteresis band width of UA69. The output power must be lower than the value set in UA69 to detect the dry pump state. The units of UA69 and UA70 are percentage where 100% means the motor rated power (value set in P02).

Function code UA73 is used to set the time delay to detect dry pump state. In other words, both the output frequency must be higher than the value set in UA54 and the output power lower than the value set in UA69 for a time longer than UA73 in order to detect the dry pump state.

Function code U124 is used to enable the alarm “OH2” in case that dry pump state is detected, by setting this function code to 1.00.

U126 U127

PV panel specifications (PV panel open circuit voltage) PV panel specifications (PV panel MPP voltage)

Function code U126 (PV panel open circuit voltage) is used to set the PV panel open circuit voltage. Function code U127 (PV panel MPP voltage) is used to set the PV panel MPP voltage.

Both parameters are fundamental for the correct operation of the Solar Pumping inverter functions. The units of both parameters are volts (DC). It is possible to set either the voltage than corresponds to a module or the value that corresponds to the complete solar panel series configuration, but the same criteria must be used for both U126 and U127.

U121 U123 U171 U135 UB88

MPP Search (Enable MPP search) MPP search (Enable manual setting of PV panel voltage set point) MPP search (Actual PV panel voltage set point) MPP search (Voltage/PID set point increase/decrease step for MPP search) MPP search (Time interval)

The maximum power operating point of the PV panel/s may change during the day due to changes of irradiance and PV panel temperature. By setting to “1.00” function code U121 (Enable MPP search), the MPP search (Maximum Power Point Tracking) function is enabled. When MPP search function is enabled the inverter will change the value of the PV panel voltage set point (function code U171) at periodic intervals, to search the maximum power operating point of the PV panel.

By setting to “1.00” function code U123 (Enable manual setting of the PV panel voltage set point), the manual setting of the PV panel (DC link) voltage set point voltage is enabled. In this case the PV panel voltage must be set manually in function code U171.

Function code U171 (Actual PV panel voltage set point) contains the current PV panel voltage set point value. If U123=0.00 the value of U171 is automatically calculated by the inverter. If U123=1.00 the value of U171 should be set manually. The units of U171 are in percentage (%), where 100% means 500 V in case of -2/-7 inverters and 1000 V in case of -4 inverters.

Function code U135 (Voltage/PID set point increase/decrease step for MPP search) is used to set the PV panel voltage set point increase/decrease for 1 step of the MPP search (MPPT) function. The units of U135 are in percentage (%), where 100% means 500 V in case of -2/-7 inverters and 1000 V in case of -4 inverters.

Function code UB88 (Time interval) is used to set in the time interval to execute the MPP search function since the last execution or since the inverter started operation. The time units of this parameter are minutes.

U172 Measurement at open circuit voltage condition (affected by multiplication factor

U127/U126)

Function code U172 does not need to be set. It indicates the voltage measured at inverter stop condition or just before inverter started to operate. The value of U172 is the result of the PV panel open circuit voltage measured (at inverter stop condition) multiplied by the factor U127/U126. The units of this parameter are in percentage (%), where 100% means 500 V in case of -2/-7 inverters and 1000 V in case of -4 inverters.

J15 U134 UD88

Sleep function (Sleep frequency) Sleep function (Power level to keep running) Sleep function (Sleep time)

Function code J15 (Sleep frequency) is used to set the sleep frequency level. If the inverter output frequency (motor frequency) is lower than the value set in this function code for a time longer than UD88 (Sleep time), then the inverter will stop due to sleep conditions. The units of this parameter are Hz.

Function code U134 (Power level to keep running) is used to set the power level to keep running. If the inverter output power (motor power) is lower than the value set in this function code for a time longer than UD88 (Sleep time), then the inverter will stop due to sleep conditions. The units of this parameter are percentage (%), where 100% means the value set in function code P02 (motor rated power).

5-26

Function code UD88 is used to set the sleep time, in other words, it contains the minimum time that the condition (either frequency or power level) should be kept in order to enter the sleep mode. The time units of this parameter are seconds.

If either of the above conditions is fulfilled the inverter will stop by sleep condition, in other words, it is not required that both conditions are fulfilled simultaneously.

Do not change the value of function code J17 from factory default value, otherwise it would interfere with the sleep and wake up functions.

U131 UD98

Wake up function (DC link voltage level to start) Wake up function (time)

Function code U131 (DC link voltage level to start) is used to set the minimum DC link voltage level to start. If the DC link voltage multiplied by the factor U127/U126 is higher than the value set in U131 for a time higher than UD98 (time) then the inverter will resume operation.

Function code UD98 is used to set the wake up time, in other words, it contains the minimum time that the condition (DC link voltage level) should be kept in order to resume operation. The units of this parameter are seconds.

Do not change the value of function code J17 from factory default value, otherwise it would interfere with the sleep and wake up functions.

U125 UI08

Big step detection (Disable) Big step detection (Dead time for next action)

These function codes are related to the big step detection function (both step UP and step DOWN). In the event of a sudden change of the PV panel conditions (especially irradiance), the voltage of the PV panel will change suddenly. If this occurs, the inverter detects this situation and changes the PV panel (DC link) voltage set point accordingly.

Function code U125 (Disable) is used to enable or disable the big step detection. If U125 is set to “1.00” the big step detection function is disabled.

Function code UI08 (Dead time for next action) is used to set the dead time between two consecutive actions of the big step detection. The dead time allows the PID controller to settle after a big step action occurs.

UH18 UH48

Big step UP detection (Level to detect big step UP) Big step UP detection (Time to follow the step UP change)

These function codes are related to the big step UP detection function. In the event that the PV panel (DC link) voltage increases suddenly due to an increase of the solar irradiance, the inverter will increase the PV panel (DC link) voltage set point.

Function code UH18 (Level to detect big step UP) is used to set the voltage level difference between PID set point and PID feedback that triggers the Big step up detection function. In other words, if PID feedback > PID set point + UH18 then the big step up function is triggered. The units of UH18 are in percentage (%), where 100% means 500 V in case of -2/-7 inverters and 1000 V in case of -4 inverters.

Function code UH48 (Time to follow the step UP change) is used to set the time that the PID set point follows the PID feedback. The time units of this parameter are seconds.

5-27

UH53 UH83 UH88

Big step DOWN detection (Level to detect big step DOWN) Big step DOWN detection (Time delay to follow the step DOWN) Big step DOWN detection (Time to follow the step DOWN change)

These function codes are related to the big step DOWN detection function. In the event that the PV panel (DC link) voltage decreases suddenly due to a decrease of the solar irradiance, the inverter will decrease the PV panel (DC link) voltage set point.

Function code UH53 (Level to detect big step DOWN) is used to set the voltage level difference between PID set point and PID feedback that triggers the Big step down detection function. In other words, if PID feedback < PID set point – UH53 for a time longer than UH83 then the big step down function is triggered. The units of UH53 are in percentage (%), where 100% means 500 V in case of -2/-7 inverters and 1000 V in case of -4 inverters.

Function code UH83 (Time delay to follow the step DOWN) is used to set the time delay to trigger the step down function. The time units of this parameter are seconds.

Function code UH88 (Time to follow the step DOWN change) is used to set the time that the PID set point follows the PID feedback. The time units of this parameter are seconds.

Chapter 6 TROUBLESHOOTING

This chapter describes troubleshooting procedures to be done when the inverter malfunctions or detects an alarm or a light alarm condition. In this chapter, first check whether any alarm code or the "light alarm" indication (

l-al

) is

displayed or not, and then proceed to the troubleshooting items.

6.1 Protective Functions

In order to prevent system down or to shorten a downtime, FRENIC-Ace is provided with various protective functions (shown in Table 6-1 below). The protective functions marked with an asterisk (*) in the table are disabled by factory default. Enable them according to your needs. The protective functions include, for example, the "heavy alarm" detection function which, upon detection of an abnormal state, displays the alarm code on the LED monitor and causes the inverter to trip, the "light alarm" detection function which displays the alarm code but lets the inverter continue the current operation, and other warning signal output functions. If any problem arises, understand the protective functions listed below and follow the procedures given in Sections 6.2 and onwards of this Manual or the User Manual for troubleshooting.

Table 6-1 Abnormal States Detectable ("Heavy Alarm" and "Light Alarm" Objects)

Protective function

Description

function code

"Heavy alarm" detection

This function detects an abnormal state, displays the corresponding alarm code, and causes the inverter to trip. See Table 6.3-1 “Various failure detections (Heavy failure objects)” for alarm codes. For details of each alarm code, see the corresponding item in the troubleshooting in Section 6.3. The inverter retains the last four alarm codes and their factors together with their running information applied when the alarm occurred, so it can display them.

H98

"Light alarm" detection*

This function detects an abnormal state categorized as a "light alarm," displays

l-al

and lets the inverter continue the current operation without tripping. Details of light alarms are selectable. Selectable details (codes) are shown in Table 6.4-1 "Various failure detections (Light alarm objects)." See Section 6.4 for the confirming method and releasing method of the light alarms.

H81 H82

Stall prevention

When the output current exceeds the current limiter level (F44) during acceleration/ deceleration or constant speed running, this function decreases the output frequency to avoid an overcurrent trip.

F44

Overload prevention control*

Before the inverter trips due to a cooling fin overheat (

0h1

) or inverter overload

(

0lu

), this function decreases the output frequency of the inverter to reduce the

load.

H70

Anti-regenerative control*

If regenerative energy returned exceeds the inverter's braking capability, this function automatically increases the deceleration time or controls the output frequency to avoid an overvoltage trip.

H69

Deceleration characteristics* (Improvement of braking performance)

During deceleration, this function increases the motor energy loss and decreases the regenerative energy returned to avoid an overvoltage trip (0u).

H71

Reference loss detection*

This function detects a frequency reference loss (due to a broken wire, etc.), issues the alarm, and continues the inverter operation at the specified frequency.

E65

Automatic lowering of carrier frequency

Before the inverter trips due to an abnormal surrounding temperature or output current, this function automatically lowers the carrier frequency to avoid a trip.

H98

Motor overload early warning*

When the inverter output current has exceeded the specified level, this function issues the "Motor overload early warning" signal before the thermal overload protection function causes the inverter to trip for motor protection (Only for the 1st motor).

E34 E35

Retry*

When the inverter has stopped because of a trip, this function allows the inverter to automatically reset and restart itself. The number of retries and the latency between stop and reset can be specified.

H04 H05

Forced stop*

Upon receipt of the "Force to stop" terminal command STOP, this function interrupts the run and other commands currently applied in order to forcedly decelerate the inverter to a stop state.

H56

Surge protection

This function protects the inverter from a surge voltage between main circuit power lines and the ground.

Momentary power failure protection*

• If a momentary power failure for 15 ms or longer occurs, a protective operation

(inverter stop) is activated.

• When momentary power failure restart is selected, the inverter restarts

automatically after voltage restoration within a set-up time (momentary power failure permissible time).

F14

6-2

6.2 Before Proceeding with Troubleshooting

• If any of the protective functions has been activated, first remove the cause. Then, after checking that all run commands are set to OFF, release the alarm. If the alarm is released while any run command is set to ON, the inverter may supply the power to the motor, running the motor.

Injury may occur.

• Even though the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input terminals L1/R, L2/S, L3/T, L1/L and L2/N, voltage may be output to inverter output terminals U, V, and W.

• Turn OFF the power and wait for at least five minutes for inverters with a capacity of FRN0012E2■-7 / FRN0115E2■-2 / FRN0072E2■-4 or below, or at least ten minutes for inverters with a capacity of FRN0085E2■-4 or above. Make sure that the LED monitor or charging lamp are turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC intermediate circuit voltage between the terminals P (+) and N (-) has dropped to the safe level (+25 VDC or below).

Electric shock may occur.

Follow the procedure below to solve problems. (1) Is wire connection correct?

See Chapter 2 "2.2.1 Basic connection diagram."

(2) Check whether an alarm code or the "light alarm" indication (

l-al

) is displayed on the LED monitor, then refer

to the indicated Section of the User Manual

 When an alarm code (excluding light alarms) is displayed To Section 6.3  If the “Light Alarm” Indication (

[ 3 ]

er7

Tuning error

Phenomena Auto-tuning failed.

Possible Causes

Check and Measures

(1) A phase was missing in the

connection between the inverter and the motor.

 Properly connect the motor to the inverter. (2) V/f or the rated current of the

motor was not properly set.

Check whether the data of function codes (F04*, F05*, H50, H51, H52, H53, H65, H66, P02*, P03*) agree with the motor modes.

(3) The wiring length between the

inverter and the motor was too long.

Check whether the wiring length between the inverter and the motor exceeds 50 m. Inverters with a small capacity are greatly affected by the wiring length.

 Review, and if necessary, change the layout of the inverter and the

motor to shorten the connection wire. Alternatively, minimize the wiring length without changing the layout.

 Disable both auto-tuning and auto-torque boost (set data of F37* to

"1").

(4) The rated capacity of the motor

was significantly different from that of the inverter.

Check whether the rated capacity of the motor is three or more ranks lower, or two or more ranks higher than that of the inverter.

 Replace the inverter with one with an appropriate capacity.  Set motor constants (P06*, P07*, P08*) manually.  Disable both auto-tuning and auto-torque boost (set data of F37* to

"1").

(5) The motor was a special type

such as a high-speed motor.

 Disable both auto-tuning and auto-torque boost (set data of F37* to

"1").

(6) Tuning (P04*=2) operation was

performed of rotating a motor in a state that brake is applied to the motor.

 Specify the tuning that does not involve the motor rotation (P04* =

1).

Instantaneous overcurrent

Phenomena The inverter momentary output current exceeded the overcurrent level.

0c1

Overcurrent occurred during acceleration.

0c2

Overcurrent occurred during deceleration.

0c3

Overcurrent occurred during running at constant speed.

Possible Causes

Check and Measures

(1) The inverter output lines were

short-circuited.

Disconnect the wiring from the inverter output terminals (U, V and W) and measure the interphase resistance of the motor wiring. Check if the resistance is too low.  Remove the short-circuited part (including replacement of the wires,

contactor, terminals and motor).

(2) Ground faults have occurred at

the inverter output lines.

Disconnect the wiring from the output terminals (U, V, and W) and perform a Megger test.  Remove the grounded parts (including replacement of the wires, contactor

terminals and motor).

(3) Overload.

Measure the motor current with a measuring device to trace the current trend. Then, use this data to judge if the trend is over the calculated load value for your system design.  If the load is too heavy, reduce it or increase the inverter capacity.

Trace the current trend and check if there are any sudden changes in the current.  If there are any sudden changes, make the load fluctuation smaller or

increase the inverter capacity.

 Enable instantaneous overcurrent limiting (H12 = 1).

(4) Excessive torque boost

specified. The manual torgue boost is set if F37* = 0, 1, 3, or

Check whether decreasing the torque boost (F09*) decreases the output current but does not stall the motor.  If no stall occurs, decrease the torque boost (F09*).

(5) The specified acceleration/

deceleration time was too short.

Check that the motor generates enough torque required during acceleration/deceleration. That torque is calculated from the moment of inertia of the load and the acceleration/deceleration times.

 Increase the acceleration/deceleration times (F07, F08, E10 through E15,

and H56).

 Enable the current limiter (F43) and torque limiter (F40, F41, E16, and E17).  Increase the inverter capacity.

(2) Cooling system for the motor is

defective.

Check if the cooling system of the motor is operating normally.  Repair or replace the cooling system of the motor.

(3) Overload.

Measure the inverter output current.  Reduce the load (e.g. Use the overload early warning (E34) and

reduce the load before the overload protection is activated.). In winter, the load tends to increase.

 Lower the temperature around the motor.  Increase the Carrier frequency (function code F26).

(4) The activation level (H27) of the

PTC thermistor for motor overheat protection was set inadequately.

Check the PTC thermistor modes and recalculate the detection voltage.  Modify the data of function code H27.

6-10

6.4 If the "Light Alarm" Indication (

l-al

) Appears on the LED Monitor

If the inverter detects a minor abnormal state, it can continue the current operation without tripping while displaying the "light alarm" indication (

l-al

) on the LED monitor. In addition to the indication l-al, the inverter blinks the KEYPAD CONTROL LED and outputs the "light alarm" signal L-ALM to a digital output terminal to alert the peripheral equipment to the occurrence of a light alarm. To use the L-ALM signal, it is necessary to assign this signal to any of the digital output terminals by setting any of function codes E20 to E21 and E27 to "98.")

Function codes H81 and H82 specify which alarms should be categorized as "light alarm." Selectable factors (codes) are the codes of light alarm objects shown in Table 6.3-1.

To display the "light alarm" factor and escape from the light alarm state, follow the instructions below.

 Check method of light alarm factors

1) Press the key to enter Programming mode.

2) Check the light alarm factor in

5_36

(Light alarm factor (latest)) under Menu #5 "Maintenance Information" in

Programming mode. The light alarm factor is displayed in alarm codes. See Table 6.3-1 for code details.



See Chapter 3 "3.4.5 Reading maintenance information" for the details of screen transition in the "Maintenance Information." It is possible to display the factors of most recent 3 light alarms in

5_37

(Light

alarm factor (last)) to

5_39

(Light alarm factor (3rd last)).

 Switching the LED monitor from the light alarm to normal display

If it is necessary to return the LED monitor to the normal display state (showing the running status such as reference frequency) temporarily before removing the light alarm factor because it takes a long time to remove the light alarm factor, for example, follow the steps below.

1) Press the key to return the LED monitor to the light alarm indication (

l-al

2) Press key in a state of light alarm display (

l-al

). Keypad display returns from light alarm display (

l-al

) to monitor display (including frequency display) in the ordinary running state. KEYPAD CONTROL LED continues blinking, though.

 Release method of light alarms

1) See function codes (H81, H82) corresponding to light alarm factors (codes) checked in the Maintenance Information to remove the occurrence factors of light alarms.

2) To return the LED monitor from the

l-al

display to the normal display state (showing the running status such

as reference frequency), press the key in Running mode. If the light alarm factor(s) has been successfully removed in step 1) above, the KEYPAD CONTROL LED

stops blinking and the digital output L-ALM also goes OFF. If any light alarm factor persists (e.g., detecting a DC fan lock), the KEYPAD CONTROL LED continues blinking and the L-ALM remains ON.

6.5 Problems with inverter settings

[ 1 ] Nothing appears on the LED monitor

Possible Causes

Check and Measures

(1) No power (neither main power

nor auxiliary control power) is supplied to the inverter.

Check the input voltage and interphase voltage unbalance.  Switch on the molded-case circuit breaker, the earth-leakage circuit

breaker (with overcurrent protective function) or the magnetic contactor.

 Check for voltage drop, phase loss, poor connections, or poor

contacts and fix them if necessary.

(2) The power for the control PCB

did not reach a sufficiently high level.

In case of supplying the inverter through the AC input terminals (L1 to L3), check if the shorting bar has been removed between terminals P1 and P(+) or if there is a poor contact between the shorting bar and those terminals.

 Mount a shorting bar or a DC reactor between terminals P1 and

P(+). In case of poor contact, tighten the screws.

6.5 When Codes Other Than Alarm Codes and Light Alarm Indication (

l-al

) are Displayed

6-11

[ 6 ] Data of function codes cannot be changed

Possible Causes Check and Measures

(1) An attempt was made to

change function code data that cannot be changed when the inverter is running.

Check if the inverter is running with Menu “Drive Monitoring” using the keypad and then confirm whether the data of the function codes can be changed when the motor is running by referring to the function code tables.

 Stop the motor then change the data of the function codes.

(2) The data of the function codes

is protected.

Check the data of function code F00 (Data protection).

 Change the data of F00 from a data protection state (F00=1 or 3) to

a data changeable state (F00=0 or 2).

(3) The WE-KP terminal command

(“Enable data change with keypad”) is not entered, though it has been assigned to a digital input terminal.

Check the data of the function codes (E01-E05, E98, E99), and check the input state by using “I/O Checking” from the Menu on the keypad.

 Input a WE-KP command through a digital input terminal.

(4) The key was not pressed. Check whether key was pressed after changing the data of the

function codes.  Press key after changing the data.

Check that

saue

is displayed on the LED monitor.

(5) The data of the function codes

F02, E01-E05, E98, E99 are not changeable.

Either one of the FWD and REV terminal commands is turned ON.

 Turn OFF both FWD and REV.

(6) The function code(s) to be

changed does not appear.

If Menu #0 “Quick Setup” (

*fnc

) is selected, only the particular

function codes appear.

 Call the menu of

!f__

!y__

by pressing key from the

quick setup (

*fnc

) state on the Menu to display the intended function code and to change the value. (See Chapter 3 Section 3.4 Table 3.4-1 “Menus Available in Programming Mode” for the details.)

[ 7 ] Function code data are not changeable (change from link functions)

Possible Causes Check and Measures

(1) An attempt was made to

change function code data that cannot be changed when the inverter is running.

 Stop the motor then change the data of the function codes.

(2) The setting of the function code

y33 (Built-in CAN communication:Operation selection) is wrong.

Check whether the setting of the function code y33 (Built -in CAN communication:Operation selection) is correct.

 Set y33 correctly.

(3) The data of the function code

F02 is not changeable.

Either one of the FWD and REV terminal commands is turned ON.

 Turn OFF both FWD and REV.
