2.3 ABOUT THE CFW-11

The CFW-11 frequency inverter is a high performance product designed for speed and torque control of three­phase induction motors. The main characteristic of this product is the “Vectrue” technology, which has the
following advantages:

Scalar control (V/f), V V W, or vector control programmable in the same product;
The vector control may be programmed as “sensorless” (which means standard motors without using

encoders) or as “vector control” with the use of an encoder;
The “sensorless” control allows high torque and fast response, even in very low speeds or at the starting;
The “vector with encoder” control allows high speed precision for the whole speed range (even with a

standstill motor);
"Optimal Braking" function for the vector control, allowing the controlled braking of the motor and avoiding

the use of the braking resistor in some applications;
“Self-Tuning” feature for vector control. It allows the automatic adjustment of the regulators and control

parameters from the identification (also automatic) of the motor parameters and load.

3.1.3 Cabinet Mounting

There are two possibilities for mounting the inverter: through the wall mounting or flange mounting (the heatsink
is mounted outside the cabinet and the cooling air of the power module is kept outside the enclosure). The
following information shall be considered in these cases:

Surface assembly:

Provide adequate exhaustion so that the internal cabinet temperature is kept within the allowable operating

range of the inverter.

The power dissipated by the inverter at its rated condition, as specified in table 8.1 "Dissipated power in

Watts - Through the wall mounting".
The cooling air flow requirements, as shown in table 3.1.
The position and diameter of the mounting holes, according to figure 3.1.

Flange assembly:

The losses specified in table 8.1 "Dissipated power in Watts - Flange mounting" will be dissipated inside the

cabinet. The remaining losses (power module) will be dissipated through the vents.

3.2 ELECTRICAL INSTALLATION

DANGER!

The following information is merely a guide for proper installation. Comply with applicable local
regulations for electrical installations.

DANGER!

Make sure the AC power supply is disconnected before starting the installation.

ATTENTION!

Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit
protection must be provided in accordance with applicable local codes.

Installation and Connection

3.2.1 Identification of the Power and Grounding Terminals

R/L1, S/L2, T/L3: AC power supply.
U/T1, V/T2, W/T3: motor connection.
DC+: this is the positive potential terminal in the DC bus circuit.
BR: braking resistor connection.
DC-: this is the negative potential terminal in the DC bus circuit.
DCL+: positive pole of the rectifier output voltage.
DCL-: negative pole of the rectifier output voltage.

Installation and Connection

3.2.2 Power / Grounding Wiring and Fuses

ATTENTION!

Use proper cable lugs for the power and grounding connection cables.

3

ATTENTION!

Sensitive equipment such as PLCs, temperature controllers, and thermal couples shall be kept at a
minimum distance of 0.25 m (9.84 in) from the frequency inverter and from the cables that connect
the inverter to the motor.

DANGER!

Improper cable connection:

- The inverter will be damaged in case the input power supply is connected to the output terminals
(U/T1, V/T2, or W/T3).

- Check all the connections before powering up the inverter.

- In case of replacing an existing inverter by a CFW-11, check if the installation and wiring is according
to the instructions listed in this manual.

ATTENTION!

Residual Current Device (RCD):

- When installing an RCD to guard against electrical shock, only devices with a trip current of 300 mA
should be used on the supply side of the inverter.

- Depending on the installation (motor cable length, cable type, multimotor configuration, etc.), the
RCD protection may be activated. Contact the RCD manufacturer for selecting the most appropriate
device to be used with inverters.

NOTE!

The wire gauge values listed in table 3.2 are merely a guide. Installation conditions and the maximum
permitted voltage drop shall be considered for the proper wiring sizing.

Input fuses

Use High Speed Fuses at the input for the protection of the inverter rectifier and wiring. Refer to table 3.2

for selecting the appropriate fuse rating (I2t shall be equal to or less than indicated in table 3.2, consider

the cold (and not the fusion) current extinction value).
In order to meet UL requirements, use class J fuses at the inverter supply with a current not higher than the

values of table 3.2.
Optionally, slow blow fuses can be used at the input. They shall be sized for 1.2 x the rated input current of

the inverter. In this case, the installation is protected against short-circuit, but not the inverter input rectifier.

This may result in major damage to the inverter in the event of an internal component failure.

- The detection of a phase-to-ground short-circuit or an insulation fault shall be processed by the user, i.e., the
user shall decide whether to indicate the fault and/or block the inverter operation.

- Contact the RCD manufacturer for selecting the most appropriate device to be used with inverters in order to
avoid nuisance tripping due to the high frequency leakage currents that flow through the leakage capacitances
of the inverter, cable, and motor system to the ground.

3.2.3.2 Dynamic Braking

ATTENTION!

For the CFW-11 frame size E models, only those with the DB option (CFW11XXXXTXODB) have the
braking IGBT incorporated to the product.

The braking torque that can be obtained from the frequency inverter without braking resistors varies from 10 %
to 35 % of the motor rated torque.

Braking resistors shall be used to obtain higher braking torques. In this case, the energy regenerated in excess
is dissipated in a resistor mounted externally to the inverter.

This type of braking is used in cases where short deceleration times are desired or when high inertia loads are
driven.

For the vector control mode, there is the possibility of using the “Optimal Braking”, eliminating in many cases
the need of dynamic braking use.

3-16

NOTE!

Set P0151 and P0185 to their maximum values (400 V or 800 V) when using dynamic braking.

Installation and Connection

3.2.3.2.1 Sizing the Braking Resistor

The following application data shall be considered for the adequate sizing of the braking resistor:

- Desired deceleration time;

- Load inertia;

- Braking duty cycle.

In any case, the effective current value and the maximum braking current value presented in table 3.4 shall
be respected.

The maximum braking current defines the minimum braking resistor value in ohms.

The DC bus voltage level for the activation of the dynamic braking function is defined by parameter P0153
(dynamic braking level).

The power of the braking resistor is a function of the deceleration time, the load inertia, and the load torque.

For most applications, a braking resistor with the value in ohms indicated in table 3.4 and the power of 20 %
of the rated driven motor power. Use wire type resistors in a ceramic support with adequate insulation voltage
and capable of withstanding high instantaneous power with respect to rated power. For critical applications with
very short deceleration times and high inertia loads (ex.: centrifuges) or short duration cycles, consult WEG for
the adequate sizing of the braking resistor.

Installation and Connection

3.2.3.2.2 Installation of the Braking Resistor

Install the braking resistor between the power terminals DC+ and BR.
Use twisted cable for the connection. Separate these cables from the signal and control cables. Size the cables
according to the application, respecting the maximum and effective currents.
If the braking resistor is installed inside the inverter cabinet, consider its additional dissipated energy when sizing
the cabinet ventilation.
Set parameter P0154 with the resistor value in ohms and parameter P0155 with the maximum resistor power
in kW.

DANGER!

The inverter has an adjustable thermal protection for the braking resistor. The braking resistor and
the braking transistor may damage if parameters P0153, P0154, and P0155 are not properly set or
if the input voltage surpasses the maximum permitted value.

The thermal protection offered by the inverter, when properly set, allows the protection of the resistor in case of
overload; however, this protection is not guaranteed in case of braking circuitry failure. In order to avoid any
damage to the resistor or risk of fire, install a thermal relay in series with the resistor and/or a thermostat in contact
with the resistor body to disconnect the input power supply of the inverter, as presented in figure 3.14.

3.2.3.3 Output Connections

ATTENTION!

The inverter has an electronic motor overload protection that shall be adjusted according to the
driven motor. When several motors are connected to the same inverter, install individual overload
relays for each motor.

ATTENTION!

The motor overload protection available at the CFW-11 is in accordance with the IEC60947-4-2
and UL508C standards.
Important considerations for the UL508C:

Trip current equal to 1.25 times the motor rated current (P0401) adjusted in the oriented start-up

menu.
The parameter P0159 maximum setting (Motor Thermal Class) is 3 (Class 20).
The parameter P0398 maximum setting (Motor Service Factor) is 1.15.

ATTENTION!

If a disconnect switch or a contactor is installed between the inverter and the motor, never operate
them with a spinning motor or with voltage at the inverter output.

Installation and Connection

3

The characteristics of the cable used for the inverter and motor interconnection, as well as the physical location
are extremely important to avoid electromagnetic interference in other equipment and to not affect the life cycle
of motor windings and motor bearings controlled by inverters.

Recommendations for the motor cables:

Unshielded Cables:

Can be used when it is not necessary to meet the European directive of electromagnetic compatibility

(89/336/EEC).

Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.), according to

table 3.5.

The emission of the cables may be reduced by installing them inside a metal conduit, which shall be grounded

at both ends.

Connect a fourth cable between the motor ground and the inverter ground.

Note:
The magnetic field created by the current circulation in these cables may induce current in close metal pieces, heat

them, and cause additional electrical losses. Therefore, keep the 3 (three) cables (U, V, W) always together.

Shielded Cables:

Are mandatory when the electromagnetic compatibility directive (89/336/EEC) shall be met, as defined by

the standard EN 61800-3 “Adjustable Speed Electrical Power Drive Systems”. These cables act mainly by
reducing the irradiated emission in the radio-frequency range.

In reference to the type and details of installation, follow the recommendations of IEC 60034-25 “Guide

for Design and Performance of Cage Induction Motors Specifically Designed for Converter Supply” – refer
to a summary in figure 3.15. Refer to the standard for further details and eventual modifications related to
new revisions.

Installation and Connection

Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.), according to

table 3.5.

The grounding system shall be well interconnected among the several installation locations such as the

grounding points of the motor and the inverter. Voltage difference or impedance between the several points
may cause the circulation of leakage currents among the equipment connected to the ground, resulting in
electromagnetic interference problems.

Symmetrical shielded cables: three concentric conductors with or without a ground conductor,

symmetrically manufactured, with an external shield of copper or aluminum.

Notes:
(1) SCu = copper or aluminum external shielding.
(2) AFe = steel or galvanized iron.
(3) PE = ground conductor.
(4) Cable shielding shall be grounded at both ends (inverter and motor). Use 360º connections for a low impedance to high-frequencies. Refer

to figure 3.16.
(5) For using the shield as a protective ground, it shall have at least 50 % of the power cables conductivity. Otherwise, add an external ground
conductor and use the shield as an EMC protection.
(6) Shielding conductivity at high-frequencies shall be at least 10 % of the power cables conductivity.

Figure 3.15 - Motor connection cables recommended by IEC 60034-25

Connection of the motor cable shield to ground: Make a connection with low impedance for high frequencies.

Example in the figure 3.16. In inverters without the Nema1 kit, connect the motor cable shield to the ground
in a similar mode, with the clamp at the inverter inner part, according to the figure 3.16.

Assemble the grounding
clamp in this position when
it's not used Nema1 kit.

3.2.4 Grounding Connections

DANGER!

Do not share the grounding wiring with other equipment that operate with high currents (ex.: high
power motors, soldering machines, etc.). When installing several inverters, follow the procedures
presented in figure 3.17 for the grounding connection.

ATTENTION!

The neutral conductor of the network shall be solidly grounded; however, this conductor shall not
be used to ground the inverter.

DANGER!

The inverter shall be connected to a Protective Ground (PE).
Observe the following:

- Minimum wire gauge for grounding connection is provided in table 3.2. Conform to local regulations
and/or electrical codes in case a different wire gauge is required.

- Connect the inverter grounding connections to a ground bus bar, to a single ground point, or to

a common grounding point (impedance ≤ 10 Ω).

- To comply with IEC 61800-5-1 standard, connect the inverter to the ground by using a single
conductor copper cable with a minimum wire gauge of 10 mm2, since the leakage current is greater
than 3.5 mA AC.

With this control connection it is possible to run the inverter in local mode with the factory default settings. This
operation mode is recommended for first-time users, since no additional control connections are required.

For the start-up in this operation mode, please follow instructions listed in chapter 5.

Control connection #2 - 2 - Wire Start/Stop function (Remote Mode).

This wiring example is valid only for the default factory settings and if the inverter is set to remote mode.
With the factory default settings, the selection of the operation mode (local/remote) is performed through the
operator key (local mode is default). Set P0220=3 to change the default setting of operator key to
remote mode.

Installation and Connection

3.3 INSTALLATION ACCORDING TO THE EUROPEAN DIRECTIVE OF ELECTROMAGNETIC COMPATIBILITY

The frame size E CFW-11 inverters have an internal RFI filter for the reduction of the electromagnetic interference.
These inverters, when properly installed, meet the requirements of the electromagnetic compatibility directive
– ‘’EMC Directive 2004/108/EC’’.

The CFW-11 inverter series has been designed only for industrial applications. Therefore, the emission limits of
harmonic currents defined by the standards EN 61000-3-2 and EN 61000-3-2/A14 are not applicable.

ATTENTION!

Do not use inverters with internal RFI filters in IT networks (neutral is not grounded or grounding
provided by a high ohm value resistor) or in grounded delta networks (“delta corner earthed”), because
these type of networks damage the filter capacitors of the inverter.

3.3.1 Conformal Installation

For the conformal installation use:

1. J1 cable in the position (XE1). Refer to item 3.2.3.1.1.

2. a) Shielded output cables (motor cables) and connect the shield at both ends (motor and inverter) with a

low impedance connection for high frequency. Use the clamp supplied with the product. Make sure there
is a good contact between the cable shield and the clamp. Refer to the figure 3.16 as an example. The
required cable separation is presented in table 3.5. For further information, please refer to item 3.2.3.

Maximum motor cable length and conduced and radiated emission levels according to the table 3.9. If

a lower conducted emission level (category C2) is wished, then an external RFI filter must be used at the
inverter input. For more information (RFI filter commercial reference, motor cable length and emission
levels) refer to the table 3.9.

b) As a second option only for the V/f and VVW control modes when using a sinusoidal output filter:
Adjust the switching frequency in 5 or 10 kHz (P0297=2 or 3) and the parameter P0350 in 2 or 3 (not

allowing the automatic reduction of the switching frequency to 2.5 kHz). Refer to tables 8.2 to 8.5 for
output current specification for 5 kHz and 10 kHz. Output cables (motor cables) that are not shielded can
be used, provided that RFI filters are installed at the inverter input and output, as presented in the table

3.10. The maximum motor cable length and the emission levels for each configuration are also presented.
Keep the separation from the other cables according to the table 3.5. Refer to the section 3.2.3 for more
information. The filters presented in table 3.10 were defined for the operation of the inverter at 5 kHz
switching frequency and rated output current as shown in tables 8.2 and 8.3. Those filters can also be
used for 10 kHz, however they are not optimized for it. In order to optimize them for use with the inverter
at 10 kHz, refer to the tables 8.4 and 8.5.

3. Use shielded control cables, keeping them separate from the other cables as described in item 3.2.5.

4. Inverter grounding according to the instructions on item 3.2.4.

This chapter describes how to:

- Check and prepare the inverter before power-up.

- Power-up the inverter and check the result.

- Set the inverter for the operation in the V/f mode based on the power
supply and motor information by using the Oriented Start-Up routine
and the Basic Application group.

NOTE!

For a detailed description of the V V W or Vector control modes and for other available functions,
please refer to the CFW-11 Software Manual.

First Time Power-Up and Start-Up

5.1 PREPARE FOR START-UP

The inverter shall have been already installed according to the recommendations listed in Chapter 3 – Installation
and Connection. The following recommendations are applicable even if the application design is different from
the suggested control connections.

DANGER!

Always disconnect the main power supply before performing any inverter connection.

1) Check if power, grounding, and control connections are correct and firmly secured.

2) Remove from the inside of the inverter all installation material left behind.

3) Verify the motor connections and if the motor voltage and current is within the rated value of the inverter.

4) Mechanically uncouple the motor from the load:
If the motor cannot be uncoupled, make sure that the chosen direction of rotation (forward or reverse) will

not result in personnel injury and/or equipment damage.

5) Return the inverter covers.

5

6) Measure the power supply voltage and verify if it is within the range listed in chapter 8.

7) Apply power to the input:
Close the input disconnect switch.

8) Check the result of the first time power-up:
The keypad should display the standar monitoring mode (figure 4.3 (a)) and the status LED should be steady

green.

5.2.2 Oriented Start-Up

There is a group of parameters named ”Oriented Start-up” that makes the inverter settings easier. Inside this
group, there is a parameter – P0317 – that shall be set to enter into the Oriented Start-up routine.

The Oriented Start-up routine allows you to quickly set up the inverter for operation with the line and motor
used. This routine prompts you for the most commonly used parameters in a logic sequence.

In order to enter into the Oriented Start-up routine, follow the steps presented in figure 5.2, first modifying
parameter P0317 to 1 and then, setting all remaining parameters as they are prompted in the display.

The use of the Oriented Start-up routine for setting the inverter parameters may lead to the automatic modification
of other internal parameters and/or variables of the inverter.

During the Oriented Start-up routine, the message “Config” will be displayed at the left top corner of the
keypad.

5.2.3 Setting Basic Application Parameters

After running the Oriented Start-up routine and properly setting the parameters, the inverter is ready to operate
in the V/f mode.

The inverter has a number of other parameters that allow its adaptation to the most different applications.
This manual presents some basic parameters that shall be set in most cases. There is a group named “Basic
Application” to make this task easier. A summary of the parameters inside this group is listed in table 5.1. There
is also a group of read only parameters that shows the value of the most important inverter variables such as
voltage, current, etc. The main parameters comprised in this group are listed in table 5.2. For further details,
please refer to the CFW-11 Software Manual.

Follow steps outlined in figure 5.3 to set the parameters of the Basic Application group.

The procedure for start-up in the V/f operation mode is finished after setting these parameters.

- Operates in low speeds, modifying the output voltage x frequency
curve to keep the torque constant.

- Compensates the voltage drop at the motor stator resistance. This
function operates in low speeds increasing the inverter output voltage
to keep the torque constant in the V/f mode.

- The optimal setting is the smallest value of P0136 that allows the
motor to start satisfactorily. An excessive value will considerably incre­ase the motor current in low speeds, and may result in a fault (F048,
F051, F071, F072, F078 or F183) or alarm (A046, A047, A050 or

- Always use a standard host/device shielded USB cable. Unshielded cables may lead to communication
errors.

- Recommended cables: Samtec:
USBC-AM-MB-B-B-S-1 (1 meter);
USBC-AM-MB-B-B-S-2 (2 meters);
USBC-AM-MB-B-B-S-3 (3 meters).

- The USB connection is galvanically isolated from the mains power supply and from other high
voltages internal to the inverter. However, the USB connection is not isolated from the Protective
Ground (PE). Use an isolated notebook for the USB connection or a desktop connected to the same
Protective Ground (PE) of the inverter.

Install the SuperDrive G2 software to control motor speed, view, or edit inverter parameters through a personal
computer (PC).

Basic procedures for transferring data from the PC to the inverter:

1. Install the SuperDrive G2 software in the PC;

2. Connect the PC to the inverter through a USB cable;

3. Start SuperDrive G2;

4. Choose “Open” and the files stored in the PC will be displayed;

5. Select the file;

6. Use the command “Write Parameters to the Drive”.
All parameters are now transferred to the inverter.

TROUBLESHOOTING AND MAINTENANCE

This chapter:

- Lists all faults and alarms that may occur.

- Indicates the possible causes of each fault and alarm.

- Lists most frequent problems and corrective actions.

- Presents instructions for periodic inspections and preventive
maintenance in the equipment.

6.1 OPERATION OF THE FAULTS AND ALARMS

When a fault is detected (fault (FXXX)):

The PWM pulses are blocked;

The keypad displays the fault code and description;
The “STATUS” LED starts flashing red;
The output relay set to "NO FAULT" opens;
Some control circuitry data is saved in the EEPROM memory:

- Keypad and EP (Electronic Pot) speed references, in case the function “Reference backup” is enabled in
P0120;

- The fault code that occurred (shifts the last nine previous faults and alarms);

- The state of the motor overload function integrator;

- The state of the operating hours counter (P0043) and the powered-up hours counter (P0042).

Troubleshooting and Maintenance

Reset the inverter to return the drive to a “READY” condition in the event of a fault. The following reset options
are available:

Removing the power supply and reapplying it (power-on reset);
Pressing the operator key (manual reset);
Through the "Reset" soft key;
Automatically by setting P0206 (auto-reset);
Through a digital input: DIx=20 (P0263 to P0270).

When an alarm situation (alarm (AXXX)) is detected:

The keypad displays the alarm code and description;
The “STATUS” LED changes to yellow;
The PWM pulses are not blocked (the inverter is still operating).

(1) The inverters are factory set for automatic fan control (P0352=2), which means that they will be turned on only when the heatsink temperature
exceeds a reference value. Therefore, the operating hours of the fan will depend on the inverter usage conditions (motor current, output frequency,
cooling air temperature, etc.). The inverter stores the number of operating hours of the fan in parameter P0045. When this parameter reaches
50000 operating hours, the keypad display will show alarm A177.

Option Kits and Accessories

OPTION KITS AND ACCESSORIES

This chapter presents:

The option kits that can be incorporated to the inverter from

the factory:

- Braking IGBT;

- Safety Stop according to EN 954-1 category 3;

- External 24 Vdc power supply for control and keypad.
Instructions for the proper use of the option kits.
The accessories that can be incorporated to the inverters.

Details for the installation, operation, and programming of the accessories are described in their own manuals
and were not included in this chapter.

7.1 OPTION KITS

Some models cannot incorporate all available option kits. Refer to table 8.1 for a detailed description of the
option kits that are available for each inverter model.

The inverter codification is described in chapter 2.

7.1.1 Braking IGBT

Inverters with the following codification: CFW11XXXXTXODB. Refer to item 3.2.3.2.

7.1.2 Nema1 Protection Degree

Inverters with the following codification: CFW11XXXXXXON1. Refer to itens 3.1.5 and 8.4.

7.1.3 Safety Stop According to EN 954-1 Category 3 (Pending Certification)

Inverters with the following codification: CFW11XXXXXXOY.

The inverters with this option are equipped with an additional board (SRB2) that contains 2 safety relays and
an interconnection cable with the power circuit.

Figure 7.1 shows the location of the SRB2 board and the location of the connector XC25 (used for the connection
of the SRB2 board signals).

The relay coils are available through the connector XC25, as presented in table 7.1.

DANGER!

The activation of the Safety Stop, i.e., disconnection of the 24 Vdc power supply from the safety relay
coil (XC25: 1(+) and 2(-); XC25:3(+) and 4(-)) does not guarantee the electrical safety of the motor
terminals (they are not isolated from the power supply in this condition).

7-1

7

Option Kits and Accessories

Operation:

1. The Safety Stop function is activated by disconnecting the 24 Vdc voltage from the safety relay coil (XC25:1(+)
and 2(-); XC25:3(+) and 4(-)).

2. Upon activation of the Safety Stop, the PWM pulses at the inverter output will be blocked and the motor will
coast to stop.

The inverter will not start the motor or generate a rotating magnetic field even in the event of an internal

failure (pending certification).

The keypad will display a message informing that the Safety Stop is active.

3. Apply 24 Vdc voltage to the safety relay coil (XC25:1(+) and 2(-); XC25:3(+) and 4(-)) to get back to normal
operation after activation of the Safety Stop.

7.1.4 24 Vdc External Control Power Supply

Inverters with the following codification: CFW11XXXXXXOW.

The use of this option kit is recommended with communication networks (Profibus, DeviceNet, etc.), since the
control circuit and the network communication interface are kept active (with power supply and responding to
the network communication commands) even in the event of main power supply interruption.

Inverters with this option have a built-in DC/DC converter with a 24 Vdc input that provides an adequate output
for the control circuit. In such manner the power supply of the control circuit will be redundant, i.e., it can be
provided by a 24 Vdc external power supply (connection as shown in figure 7.2) or by the standard internal
switched-mode power supply of the inverter.

7-2

Option Kits and Accessories

Observe that the inverters with the external 24 Vdc power supply option use terminals XC1:11 and 13 as the
input for the external power supply and no longer as an output as in the standard inverter (figure 7.2).

In case of interruption of the external 24 Vdc power source, the digital inputs/outputs and analog outputs will
have no power supply, even if the mains power is on. Therefore, it is recommended to keep the 24 Vdc power
source always connected to terminals XC1:11 and 13.

The keypad displays warnings indicating the inverter status: if the 24 Vdc power source is connected, if the
mains power source is connected, etc.

Note:
(1) Steady-state rated current in the following conditions:

- Indicated carrier frequencies. For operation with higher switching frequencies (carrier frequency) it is necessary
to derate output current according to the tables 8.2 to 8.5.

- Surrounding air temperature: -10 °C to 45 °C (14 °F to 113 °F). The inverter is capable of operating with an
maximum surrounding air temperature of 55 °C (131 °F) if an output current derating of 2 % is applied for
each ºC (or 1.11 % each °F) above 45 °C (113 °F). This output current derating is valid for all the switching
frequencies.

- Relative air humidity: 5 % to 90 % non-condensing.

- Altitude: 1000 m (3,300 ft). Above 1000 m (3,300 ft) up to 4000 m (13,200 ft) the output current shall be
derated by 1 % for each 100 m (330 ft) above 1000 m (3,300 ft).

- Ambient with pollution degree 2 (according to EN50178 and UL508C).

Figure 8.1 (a) and (b) - Overload curves for the IGBTs

Depending on the inverter usage conditions (surrounding air temperature, output frequency, possibility or not
of reducing the carrier frequency, etc.), the maximum time for operation of the inverter with overload may be
reduced.

(3) The carrier frequency may be automatically reduced to 2.5 kHz depending on the operating conditions
(surrounding air temperature, output current, etc.) - if P0350=0 or 1.
If it is necessary to operate always in 5 kHz, set P0350=2 or 3 and consider the nominal current values of the
table 8.2 and 8.3. Note that in this case it is necessary to apply the derating to the nominal output current.

(4) The motor ratings are merely a guide for 230 V or 460 V, IV pole WEG motors. The adequate inverter sizing
shall be based on the rated current of the motor used.

(5) The information provided about the inverter losses is valid for the rated operating condition, i.e., for rated
output current and rated carrier frequency.

(6) The dissipated power provided for flange mounting corresponds to the total inverter losses disregarding the
power module (IGBT and rectifier) losses.
