2.2 Terms AND DEFINITIONS
Normal Duty Cycle (ND): Inverter duty cycle that defines the maximum continuous operation current (IRAT-ND) and
the overload current (110 % for 1 minute). The ND cycle is selected by setting P0298 (Application) = 0 (Normal
Duty (ND)). This duty cycle shall be used for the operation of motors that are not subjected to high torque loads
(with respect to the motor rated torque) during its operation, starting, acceleration, or deceleration.
IRAT-ND: Inverter rated current for use with the normal duty (ND) cycle.
Overload: 1.1 x IRAT-ND/ 1 minute.
Heavy Duty Cycle (HD): Inverter duty cycle that defines the maximum continuous operation current (IRAT-HD)
and the overload current (150 % for 1 minute). The HD cycle is selected by setting P0298 (Application) = 1
(Heavy Duty (HD)). This duty cycle shall be used for the operation of motors that are subjected to high torque
(with respect to the motor rated torque) during its operation, starting, acceleration, or deceleration.
IRAT-HD: Inverter rated current for use with the heavy duty (HD) cycle.
Overload: 1.5 x IRAT-HD / 1 minute.
Rectifier: Input circuit of inverters that transforms the AC input voltage in DC voltage. It is composed of power
diodes.
Pre-charge Circuit: Charges the DC bus capacitors with limited current, which avoids higher peak currents
at the inverter power-up.
2-1
General Instructions
DC Bus: Inverter intermediate circuit; DC voltage obtained from the rectification of the AC input voltage or
from an external power supply; feeds the output inverter bridge with IGBTs.
Power modules U, V, and W: Set of two IGBTs of the inverter output phases U, V, and W.
IGBT: Insulated Gate Bipolar Transistor; basic component of the output inverter bridge. The IGBT works as an
electronic switch in the saturated (closed switch) and cut-off (open switch) modes.
Braking IGBT: Works as a switch to activate the braking resistors. It is controlled by the DC bus voltage
level.
PTC: Resistor which resistance value in ohms increases proportionally to the temperature increase; used as a
temperature sensor in electrical motors.
2
NTC: Resistor which resistance value in ohms decreases proportionally to the temperature increase; used as a
temperature sensor in power modules.
Keypad: Device that allows controlling the motor, and viewing/editing inverter parameters. It is composed of
motor control keys, navigation keys, and a graphic LCD display.
FLASH memory: Non-volatile memory that can be electronically written and erased.
RAM memory: Random Access Memory (volatile).
USB: Universal Serial Bus; is a serial bus standard that allows devices to be connected using the ”Plug and
Play” concept.
PE: Protective Earth.
RFI Filter: Radio-Frequency Interference Filter for interference reduction in the Radio-Frequency range.
PWM: Pulse Width Modulation; pulsed voltage that feeds the motor.
Switching frequency: Frequency of the IGBTs switching in the inverter bridge, normally expressed in kHz.
General enable: When activated, this function accelerates the motor via acceleration ramp set in the inverter.
When deactivated, this function immediately blocks the PWM pulses. The general enable function may be
controlled through a digital input set to this function or via serial communication.
Start/Stop: When enabled in the inverter (start), this function accelerates the motor via acceleration ramp up
to the speed reference. When disabled (stop), this function decelerates the motor via deceleration ramp up to
the complete motor stop; at this point, the PWM pulses are blocked. The start/stop function may be controlled
through a digital input set for this function or via serial communication. The operator keys
and
of the
keypad work in a similar way:
=Start,
=Stop.

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: allows the controlled braking of the motor, eliminating
the additional braking resistors 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.

Installation and Connection
INSTALLATION AND CONNECTION
This chapter provides information on installing and wiring the CFW-11.
The instructions and guidelines listed in this manual shall be followed
to guarantee personnel and equipment safety, as well as the proper
operation of the inverter.
3.1 MECHANICAL INSTALLATION
3.1.1 Installation Environment
Avoid installing the inverter in an area with:
Direct exposure to sunlight, rain, high humidity, or sea-air;
Inflammable or corrosive gases or liquids;
Excessive vibration;
Dust, metallic particles, and oil mist.
Environment conditions for the operation of the inverter:
Temperature: -10 ºC to 50 ºC (14 °F to 122 °F) – standard conditions (surrounding the inverter).
From 50 ºC to 60 ºC (122 °F to 140 °F) - 2 % of current derating for each Celsius degree above 50 ºC (122 °F).
Humidity: from 5 % to 90 % non-condensing.
Altitude: up to 1000 m (3,300 ft) - standard conditions (no derating required).
From 1000 m to 4000 m (3,300 ft to 13,200 ft) - 1 % of current derating for each 100 m (330 ft) above
1000 m (3,300 ft) altitude.
Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution. Condensation shall
not originate conduction through the accumulated residues.
3.1.2 Mounting Considerations
Consult the inverter weight at the table 8.1.
Mount the inverter in the upright position on a flat and vertical surface.
External dimensions and fixing holes position according to the figure 3.1. Refer to the section 8.3 for more
details.
First mark the mounting points and drill the mouting holes. Then, position the inverter and firmly tighten the screws
in all four corners to secure the inverter.
Minimum mounting clearances requirements for proper cooling air circulation are specified in figures 3.2 and 3.3.
Inverters of frames A, B, and C can be arranged side-by-side with no clearance required between them. In this
case, the top cover must be removed as shown in figure 3.3 (b).
Do not install heat sensitive components right above the inverter.
ATTENTION!
When arranging two or more inverters vertically, respect the minimum clearance A + B (figure 3.2) and
provide an air deflecting plate so that the heat rising up from the bottom inverter does not affect the
top inverter.

Installation and Connection
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:
Through the wall mounting:
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 mounting:
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.
The mounting supports shall be removed and repositioned as illustrated in figure 3.4.

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.
3.2.1 Identification of the Power and Grounding Terminals
NOTE!
Models CFW110006B2 and CFW110007B2 may operate with two phases only (single-phase power
supply) without rated output current derating. In this case, the single-phase power supply may be
connected to two of any input terminals.
Models CFW110006S2OFA, CFW110007S2OFA, and CFW110010S2 only operate with singlephase power supply. In this case, the single-phase power supply shall be connected to terminals
R/L1 and S/L2.
R/L1, S/L2, T/L3: AC power supply.
DC-: this is the negative potential terminal in the DC bus circuit.
BR: braking resistor connection.
DC+: this is the positive potential terminal in the DC bus circuit.
U/T1, V/T2, W/T3: motor connection.

3.2.2 Power / Grounding Wiring and Fuses
ATTENTION!
Provide adequate terminals when flexible cables are used for the power and grounding
connections.
ATTENTION!
Sensitive equipment such as PLCs, temperature controllers, and thermal couples shall be kept at a
minimum distance of 0.25 m (0.82 ft) 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.

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).
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.

Provide a disconnect device for the input power supply of the inverter.
This device shall disconnect the input power supply for the inverter when needed (for instance, during
servicing).
ATTENTION!
The power supply that feeds the inverter shall have a grounded neutral. In case of IT networks, follow
the instructions described in item 3.2.3.1.1.
NOTE!
The input power supply voltage shall be compatible with the inverter rated voltage.
NOTE!
Power factor correction capacitors are not needed at the inverter input (R, S, T) and shall not be
installed at the output of the inverter (U, V, W).
AC power supply considerations
The CFW-11 inverters are suitable for use on a circuit capable of deliviering up to a maximum of 100.000
Arms symmetrical (240 V / 480 V).
If the CFW-11 inverters are installed in a circuit capable of delivering more than100.000 Arms symmetrical,
it is required to install adequate protection devices such as fuses or circuit breakers.
3.2.3.1.1 IT Networks
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 earth”), because
these type of networks damage the inverter filter capacitors.
3-12
Installation and Connection
The CFW-11 inverter series, except the models with internal RFI filters – CFW11XXXXXXOFA, can be normally
used in IT networks. If the available model is equipped with an internal filter, remove the two grounding screws
from the filter capacitors as presented in figure 3.11. Remove the keypad and the front cover to have access to
these screws in frames A, B, and C. For frame D, the bottom front cover shall be removed as well.
Consider the following items for the use of protection devices on the supply side of the inverter such as residual
current devices or isolation monitors:
- 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
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.
The “Optimal Braking” feature may be used with the vector control mode, which eliminates in most cases the
need of an external braking resistor.
NOTE!
Set P0151 and P0185 to their maximum values (400 V or 800 V) when using dynamic braking.
3
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 3.3 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 3.3 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.

Notes:
(1) The effective braking current presented is just an indicative value, because it depends on the braking duty
cycle. The effective braking current can be obtained from the equation below, where tbr is given in minutes
and corresponds to the sum of all braking times during the most severe cycle of 5 (five) minutes.
Ieffective = Imax x
tbr
5
(2) The Pmax and PR values (maximum and mean power of the braking resistor respectively) presented are valid
for the recommended resistors and for the effective braking currents presented in table 3.3. The resistor
power shall be changed according to the braking duty cycle.
(3) For specifications on the recommended terminal type (screw and tightening torque) for the connection of
the braking resistor (terminals DC+ and BR), refer to the DC+ terminal specification at the table 3.2. There
are plastic covers in front of the DC-, DC+ and BR terminals at the frame size C. It is necessary to break
off those covers in order to get access to these terminals.
3-15
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 3.12.

Installation and Connection
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!
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.
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), unless the RFI filters be used as presented in the table 3.9 and section 3.3.1.
Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.), according to
table 3.4.
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”, unless the RFI filters be used
as presented in the table 3.9 and section 3.3.1. These cables act mainly by reducing the irradiated emission
in the radio-frequency range.
Are mandatory when RFI filters, internally or externally mounted, are installed at the inverter input, unless
the RFI filters be used as presented in the table 3.9 and section 3.3.1.
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 3.13. Refer to the standard for further details and eventual modifications related to
new revisions.
Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.), according to
table 3.4.
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.

Notes:
(1) SCu = copper or aluminum external shielding
(2) AFe = steel or galvanized iron

(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 3.14.
(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 3.13 - Motor connection cables recommended by IEC 60034-25
Connection of the motor cable shield to ground:
The CFW-11 inverter series has some accessories that make the connection of the motor cable shield to the
ground easier, resulting in a low impedance connection for high-frequencies.
There is an option accessory for frames A, B, and C named “Kit for power cables shielding – PCSx-01” (refer
to item 7.2) that can be adapted in the bottom of the enclosure of these frames. See an example of the cable
connection with the accessory PCSx-01 in figure 3.14. The kit for power cables shielding is provided for the
inverters with internal RFI filters (CFW11XXXXXXOFA).
When the “Conduit Kit” (refer to item 7.2) is used for frames A, B, and C, motor cable shield shall be grounded
similarly as in figure 3.14.
For frame D, there is a provision for motor cable shield grounding in the standard inverter enclosure.

Installation and Connection
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 3.15 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 or a two-conductor cable with the
same wire gauge of the grounding cable specified in table 3.2, since the leakage current is greater
than 3.5 mA AC.

3.2.6 Typical Control Connections
Control connection #1 - Start/Stop function controlled from the keypad (Local Mode).
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 inverters with the option FA (CFW11XXXXXXOFA) are equipped with an internal RFI filter to reduce
the electromagnetic interference. These inverters, when properly installed, meet the requirements of the
electromagnetic compatibility directive - “EMC Directive 89/336/EEC” – with the complement 93/68/EEC.
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/A 14 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 earth”), because
these type of networks damage the filter capacitors of the inverter.
3.3.1 Conformal Installation
3
For the conformal installation use:
1. Inverters with internal RFI filters option CFW11XXXXXXOFA (with grounding screws of the internal RFI filter
capacitors).
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 PCSx-01 kit supplied with the frame size A, B and
C inverters. For the frame sizes D models, use the clamps supplied with the product. Make sure there is
a good contact between the cable shield and the clamps. Refer to the figure 3.14 as an example. The
required cable separation is presented in table 3.4. For further information, please refer to item 3.2.3.
Maximum motor cable length and conduced and radiated emission levels according to the table 3.8.
If a lower emission level and/or a longer motor cable were 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 3.8.
b) As a second option only for the V/f and VVW control modes when using a sinusoidal output filter:
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 3.9. In that table the maximum cable length and
the emission levels for each configuration are also presented. Keep the separation from the other cables
according to the table 3.4. Refer to the section 3.2.3 for more information.
3. 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.

First Time Power-Up and Start-Up
First time power-up and
start-up
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.
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.
5
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.
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.

- The factory default setting is for “Ramp Hold”: if the motor current
exceeds the value set at P0135 during the acceleration or deceleration, the motor speed will not be increased (acceleration) or decreased (deceleration) anymore. When the motor current reaches a
value below the programmed in P0135, the motor speed is again
increased or decreased.

- Operates in low speeds, modifying the output voltage x frequency

- 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,

Note:
(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 50.000 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:
- RFI filter;
- 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 RFI Filter
Inverters with the following codification: CFW11XXXXXXOFA. Refer to table 8.1 for information on availability
of this option kit for each inverter model.
ATTENTION!
Do not use inverters with internal RFI filters in IT networks (ungrounded neutral or grounding provided
by a high ohm value resistor) or in grounded delta networks (“delta corner earth”). These type of
installations will damage the inverter filter capacitors.
The RFI filter reduces the conducted noise of the inverter to the electrical supply system in the high frequency
range (>150 kHz).
The RFI filter is required for the compliance with conducted emissions limits established by the Electromagnetic
Compatibility standards such as EN 61800-3 and EN 55011.
For the proper operation of the RFI filter, please follow the instructions listed in item 3.3 for the installation of
the inverter, motor, cables, etc. This chapter also provides information on the compliance of these standards,
such as the maximum motor cable length.
7.1.2 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 (SRB) that contains 2 safety relays and an
interconnection cable with the power circuit.
7-1
7
Option Kits and Accessories
Figure 7.1 shows the location of the SRB board and the location of the connector XC25 (used for the connection
of the SRB board signals) in the inverter.
The relay coils are available through the connector XC25, as presented in figure 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).
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.

7.1.3 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.
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.

Technical Specifications
Note:
(1) Steady-state rated current in the following conditions:
- Indicated carrier frequencies. For operation with a 10 kHz carrier frequency it is necessary to derate the
output current according to table 8.2.
- Surrounding air temperature: -10 °C to 50 °C (14 °F to 122 °F). The inverter is capable of operating with an maximum
surrounding air temperature of 60 °C (140 °F) if an output current derating of 2 % is applied for each ºC above
50 °C (122 °F).
- 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).
(2) Table 8.1 presents only two points of the overload curve (activation time of 1 min and 3 s). The complete

Technical Specifications
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, 1, or 4.
(4) The motor ratings are merely a guide for 220 V or 440 V, IV pole WEG motors. The adequate inverter sizing
shall be based on the rated current of the motor used.
(5) Models that can operate from single-phase or three-phase power supply have their input current stated in
both cases. The single-phase input current is provided first.
(6) The information provided about the inverter losses is valid for the rated operating condition, i.e., for rated
output current and rated carrier frequency.
(7) The dissipated power provided for flange mounting corresponds to the total inverter losses disregarding the
power module (IGBT and rectifier) losses.
(8) If the inverter is to be provided with this option, it should be specified in the intelligent identification code of the
inverter. Exception: the RFI filter is already incorporated in models CFW110006S2OFA and CFW110007S2OFA.
For further details, please refer to chapter 2.
