1. SAFETY INFORMATION AND CONFORMITY TO STANDARDS
1.1 Safety Information
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.
Application
•FRENIC-Eco 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.
•FRENIC-Eco may not be used for a life-support system or other purposes directly related to the human safety.
•Though FRENIC-Eco is manufactured under strict quality control, install safety devices for applications where serious accidents or material losses
are foreseen in relation to the failure of it. An accident could occur.
Installation
•Install the inverter on a nonflammable material such as metal. Otherwise fire could occur.
•Do not place flammable matter nearby. Doing so could cause fire.
•Do not support the inverter by its terminal block 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. 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.
•Do not get on a shipping box.
•Do not stack shipping boxes higher than the indicated information printed on those boxes. Doing so could cause injuries.
Maintenance and inspection,and parts replacement
•Turn the power OFF and wait for at least five minutes for models of 30 kW or below, or ten minutes for models of 37 kW or above,before starting
inspection. Further, check that the LED monitor is unlit, and check the DC link bus voltage between the P (+) and N (-) terminals to be lower than
25 VDC. Otherwise,electric shock could occur.
•Maintenance, inspection,and parts replacement should be made only by qualified persons.
•Take off the watch, rings and other metallic matter before starting work.
•Use insulated tools. Otherwise,electric shock or injuries could occur.
Disposal
•Handle the inverter as an industrial waste when disposing of it. Otherwise injuries could occur.
Others
•Never attempt to modify the inverter. Doing so could cause electric shock or injuries.
Wiring
•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 power lines.Use the devices within the
recommended current range.

•Use wires in the specified size. Otherwise, fire could occur.
•Do not use one multicore cable in order to connect several inverters with motors.
•Do not connect a surge killer to the inverter's output (secondary) circuit. Doing so could cause fire.
•Ground the inverter following Class C or Class D specifications or national/local electric code, depending on the input (primary) voltage of the
inverter. Otherwise, electric shock could occur.
•Qualified electricians should carry out wiring.
•Be sure to perform wiring after turning the power OFF.Otherwise,electric shock could occur.
•Be sure to perform wiring after installing the inverter body. Otherwise,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 fire or an accident could occur.
•Do not connect the power source wires to output terminals (U, V, and W). Doing so could cause fire or an accident.
•Generally, control signal wires are not enforced-insulated. If they accidentally touch any of hot power lines, their insulation coat may break for any
reasons. In such a case, an extremely high voltage may be applied to the signal lines. Make a complete remedy to protect the signal line from
contacting any hot high voltage lines. Otherwise,an accident or electric shock could occur.
•Wire the three-phase motor to terminals U, V, and Wof the inverter, aligning phases each other. Otherwise injuries could occur.
•The inverter, motor and wiring generate electric noise. Take care of malfunction of the nearby sensors and devices. To prevent the motor from
malfunctioning, implement noise control measures. Otherwise an accident could occur.
Setting control switches
•Before setting up any internal control switches, turn OFF the power, wait more than five minutes for models of 30 kW or below, or ten minutes for
models of 37 kW or above, and make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P (+)
and N (-) has dropped below a safe voltage (+25 VDC).Otherwise electric shock could occur.
Operation
•Be sure to install the terminal block cover and the front cover before turning the power ON. Do not remove the coverswhile power is applied.
Otherwise electric shock could occur.
•Do not operate switches with wet hands. Doing so could cause electric shock.
•If the retry function has been selected, the inverter may automatically restart and drive the motor depending on the cause of tripping.
(Design the machinery or equipment so that human safety is ensured after restarting.)
•If the stall prevention function (current limiter), automatic deceleration, and overload prevention control have been selected, the inverter may
operate at an acceleration/deceleration time or frequency different from the commanded ones. Design the machine so that safety is ensured even
in such cases. Otherwise an accident could occur.
•The STOP key is only effective when function setting (Function code F02) has been established to enable the STOP key. Prepare an emergency
stop switch separately. If you disable the STOP key priority function and enable operation by external commands, you cannot emergency-stop the
inverter using the STOP key on the built-in keypad.
•If an alarm reset is made with the Run command signal turned ON, a sudden start will occur. Ensure that the Run command signal is turned OFF
in advance. Otherwise an accident could occur.
•If you enable the "restart mode after instantaneous power failure"(Function code F14 = 3, 4, or 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 you set the function codes wrongly or without completely understanding this instruction manual and the FRENIC-Eco User's Manual (MEH456),
the motor may rotate with a torque or at a speed not permitted for the machine. An accident or injuries could occur.
•Do not touch the inverter terminals while the power is applied to the inverter even if the inverter stops. Doing so could cause electric shock.
•Do not turn the main circuit power (circuit breaker) ON or OFF in order to start or stop inverter operation. Doing so could cause failure.
•Do not touch the heat sink because they become very hot. Doing so could cause burns.
•Setting the inverter to high speeds is easy. Before changing the frequency (speed) setting, check the specifications of the motor and machinery.
•The brake function of the inverter does not provide mechanical holding means. Injuries could occur.
GENERAL PRECAUTIONS

2. Mechanical Installation
2.1 Installing the Inverter
Mounting base
The inverter should be mounted on a base made of material that can withstand heat sink
temperature, which can rise up to 90ºC approx. during inverter operation.
Clearances
Ensure that the minimum clearances indicated are maintained at all times. When installing the
inverter in the enclosure of your system, take extra care with ventilation inside the enclosure
as the temperature around the inverter will tend to increase. Do not install the inverter in a
small enclosure with poor ventilation.
*For 37Kw or above a 50 mm clearance is needed instead of 10 mm (left and right sides).
As long as the ambient temperature is 40°C or lower, 5.5 kW or lower inverters may be
mounted side-by-side without any gap between them.
For others inverters, please follow the clearances needed.
2.2 Mounting Direction
Horizontal layout is recommended when two or more inverters are to be installed in an equipment or enclosure. If it is necessary to
mount the inverters vertically, install a partition plate or the like between the inverters so that any heat radiating from an inverter will
not affect the one/s above.
2.3 Removing and Mounting the Terminal Block (TB) Cover and the Front Cover
To remove the TB cover, loosen the fastening screw on it, hold the dimple (labelled “PULL”), and pull it up towards you.
To remove the front cover, hold it with both hands, slide it downward, disengage the latch at the top from the inverter, tilt the front
cover toward you, and pull it upward.

5.1.1 Inspection and preparation prior to powering on
Check the following prior to starting powering on.
(1) Check if connection is correct.
Especially check if the power wires are connected to the inverter input terminals L1/R, L2/S and L3/T, and output
terminals U, V and W respectively and that the grounding wires are connected to the ground electrodes correctly. Note
that FRENIC-Eco series inverter is designed for three phase input and driving three phase motors.
•Do not connect power supply wires to the inverter output terminals U, V, and W. Otherwise, the inverter may
be broken if you turn the power on.
•Be sure to connect the grounding wires of the inverter and the motor to the ground electrodes.
Otherwise, electric shock may occur.
(2) Check for short circuits between terminals and exposed live
parts and ground faults.
(3) Check for loose terminals, connectors and screws.
(4) Check if the motor is separated from mechanical equipment.
(5) Turn the switches off so that the inverter does not start or
operate erroneously at power-on.
(6) Check if safety measures are taken against runaway of the
system, e.g., a defense to protect people from unexpectedly
approaching your power system.

6. FUNCTION CODES
6.1 Function Codes Tables
Function codes enable the FRENIC-Eco series of inverters to be set up to match your system requirements.
Each function code consists of a 3-letter string. The first letter is an alphabet that identifies its group and the following two letters
are numerals that identify each individual code in the group. The function codes are classified into eight groups: Fundamental
Functions (F codes), Extension Terminal Functions (E codes), Control Functions of Frequency (C codes), Motor Parameters (P
codes), High Performance Functions (H codes), Application Functions (J codes),Link Function (y codes) and. Option Function (o
codes) To determine the property of each function code, set data to the function code.
For Option function (o codes), refer to the instruction manual for the option.
nUsing negative logic for programmable I/O terminals
The negative logic signaling system can be used for the digital input and output terminals by setting the function codes specifying
the properties for those terminals. Negative logic refers to inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or
output signal. An ON-active signal (the function takes effect if the terminal is short-circuited.) in the normal logic system is
functionally equivalent to OFF-active signal (the function takes effect if the terminal is opened.) in the negative logic system.
To set the negative logic system for an I/O signal terminal, display data of 1000s (by adding 1000 to the data for the normal logic)
in the corresponding function code and then press the key.
For example, if a coast-to-stop command (BX: data = 7) is assigned to any one of digital input terminals [X1] to [X3] by setting
any of function codes E01 through E03, then turning (BX) on will make the motor coast to a stop. Similarly, if the coast-to-stop
command (BX: data = 1007) is assigned, turning (BX) off will make the motor coast to a stop.
The following tables list the function codes available for the FRENIC-Eco series of inverters.

F01 To do this
0Enable and keys on the built-in keypad. (Refer to Chapter 4 "OPERATION USING THE KEYPAD.")
1Enable the voltage input to terminal [12] (0 to 10 VDC).
2Enable the current input to terminal [C1] (4 to 20 mA DC).
3Enable the sum of voltage and current inputs to terminals [12] and [C1]. See the two items listed above for the
setting range and maximum frequencies.
Note: If the sum exceeds the maximum frequency, the maximum frequency will apply.
5Enable the voltage input to terminal [V2] (0 to 10 VDC).
7Enable (UP) and (DOWN) commands assigned to the digital input terminals
(UP) command (data=17) and (DOWN) command (data=18) to the input terminals [X1] to [X5].
Certain setti
ng means (e.g., communication link and multistep frequency) have priority over these settings. For details,
refer to the block diagram in the FRENIC-
Eco User’s Manual (MEH456), Chapter 4, Section 4.2 "Drive Frequency
Command Generator."
F02 Operation Method
Select the source issuing a run command for running the motor.
F02 Running Mode Source of Run Command
0Running per keypad
(rotation direction:
determined by terminal
block)
Enables the key and the key on the keypad to start and stop the motor. In the
case of a standard keypad, the direction of rotation is determined by the commands
given at terminals FWD and REV.
In the case of a multi-functional keypad, there is no need to specify the direction of
rotation.
1External signal Enables the external signals given at terminals FWD and REV to run the motor.
2Running per keypad
(forward rotation)
Enables the key and the key on the keypad to start and stop the motor. There is
no need to specify the direction of rotation, since only forward rotation is allowed.
In the case of a multi-functional keypad, only the FWD key is effective.
3Running per keypad
(reverse rotation)
Enables the key and the key on the keypad to start and stop the motor. There is
no need to specify the direction of rotation, since only reverse rotation is allowed.
In the case of a multi-functional keypad, only the REV key is effective.
When function code F02 = 0 or 1, the forward running/
stopping function (FWD) and the reverse running /stopping
function (REV) must be assigned to terminals FWD and REV, respectively.
In addition to the function code F02 described above, there are several other means available with priority over F02.
For details, refer to the block diagram in FRENIC-Eco User’s Manual (MEH456), Chapter 4, Section 4.3 "Drive
Command Generator."
•Digital input commands (FWD) and (REV) are valid for specifying the motor ro
tation direction, and the commands
(FWD2) and (REV2) are invalid.
•
If you have assigned the (FWD) or (REV) function to the [FWD] or [REV] terminal, you cannot change the setting of
function code F02 while the terminals [FWD] and [PLC]* or the terminals [REV] and [CM]* are short-circuited.
•
If you have specified the external signal (F02 = 1) as the running command and have assigned functions other than
the (FWD) or (REV) function to the [FWD] or [REV] terminal, caution should be exercised in changing the s
ettings.
Because, if under this condition you assign the (FWD) or (REV) function to the [FWD] or [REV] terminal while the
terminals [FWD] and [PLC]* or the terminals [REV] and [PLC]* are short-circuited, the motor would start running.
*[PLC] replaces with [CM] for SINK mode.
When "Local" is selected by Remote/Local switching, the operation of the keypad concerning run commands varies
with the setting of F02. For details, refer to Chapter 4.

F03 Maximum Frequency
Sets the maximum frequency to drive the motor.
Setting the frequency out of the range rated for the equipment driven by the inverter may cause damage or a
dangerous situation. Set a maximum frequency appropriate for the equipment.
The inverter can easily set high-speed operation. When changing the speed setting, carefully check the specifications of
motors or equipment beforehand.
Otherwise injuries could occur.
If you modify the
data of F03 to apply a higher drive frequency, concurrently change the data of F15 for a high
frequency limiter suitable to the drive frequency.
F04
F05
Base Frequency
Rated Voltage (at base frequency)
These function codes set the base frequency and the voltage at the base frequency essentially required for running the
motor properly.
nBase Frequency (F04)
Set the rated frequency printed on the nameplate located on the motor.
nRated Voltage (at base frequency) (F05)
Set 0 or the rated voltage printed on the nameplate labeled on the motor.
-If 0 is set, the inverter supplies voltage equivalent to that of the power source of the inverter at the base frequency. In
this case, the output voltage will vary in line with any variance in input voltage.
-If the data is set to anything other than 0, the inverter automatically keeps the output voltage constant in line with the
setting. When any of the automatic torque boost settings, automatic energy saving is active, the voltage settings
should be equal to the rating of the motor.
F07
F08
Acceleration Time 1
Deceleration Time 1
The acceleration time specifies the length of time the frequency increases from 0 Hz to the maximum frequency. The
deceleration time specifies the length of time the frequency decreases from the maximum frequency down to 0 Hz.

Torque Boost
Load Selection/Auto Torque Boost/Auto Energy Saving Operation
nTorque Boost
• Manual torque boost per F09
In torque boost using F09, you are adding a certain amount of voltage, regardless of the load, to the output voltage that
is determined by the basic V/f characteristics. To secure a sufficient starting torque, manually adjust the output voltage
to optimally match the motor and its load by using F09. Select an appropriate level that guarantees smooth start-up
and yet does not cause over-excitation with no or light load.
Torque boost per F09 ensures high driving stability since the output voltage remains constant regardless of the size of
the load.
Specify the value for function code F09 in ratio (percentage) to the base frequency. At factory shipment, it is preset to a
level that ensures a certain amount (50%) of starting torque.
Specifying a high torque boost level will generate a high torque, but may cause overcurrent due to over-
excitation
when there is no or very light load. If you continue to drive the motor, it may overheat. To avoid such a si
tuation, adjust
torque boost to an appropriate level.
These function codes optimize the operation in accordance with the characteristics of the load. Function code F37
specifies V/f pattern, torque boost, and automatic energy saving functions. F09 specifies the amount of torque boost in
order to provide sufficient starting torque.

F10 to
F12
Electronic Thermal Overload for Motor Protection
(Select the motor property, overload detection level, and thermal time constant)
F10 through F12 set the thermal characteristics of the motor for electronic thermal simulation, which is used to detect
overload conditions of the motor. More specifically, F10 specifies the motor characteristics, F11 the overload detection
level, and F12 the thermal time constant.
Thermal characteristics of the motor specified by these function codes are also used for the overload early warning.
Therefore, even if you need only the overload early warn
ing, set these characteristics data to function codes F10 and
F12. To disable electronic thermal simulation, set function code F11 to "0.00."
