2.3 ABOUT THE CFW-11M G2

The CFW-11M G2 inverters are the second generation of the CFW-11M inverters. The main differences in relation to the previous generation are the following:

 Smaller. The CFW-11M G2 is shorter and slimmer than the CFW-11M, allowing the installation of 3 UP11 G2 in

panels featuring 800 mm wide and 2000 mm high columns.

 More modern. State-of-the-art components increased the inverter power.

The CFW11 G2 is a high-performance product which enables speed and torque control of three-phase induction motors. The main characteristic of this product is the "Vectrue" technology, which provides the following advantages:

 High compactness and power density.

 Scalar control (V/f), VVW or vector control programmable in the same product.

 The vector control can be programmed as “sensorless” (which means standard motors, without requiring

encoder) or as “vector control” with encoder on the motor.

 The “sensorless” vector control allows high torque and fast response, even at very low speeds or at the start.

 The “vector with encoder” control allows high speed precision for the whole speed range (even with a standstill

motor).

 "Optimal Braking" function for vector control, allowing the controlled braking of the motor, eliminating the use of

braking resistor in some applications.

 "Self-Tuning" function for vector control: It allows the automatic setting of control parameters and regulators

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

The CFW-11M G2 inverters present a modular structure, with configurations from one to five power units (UP11 G2), one control unit (UC11 G2) and wiring cables. The modular assembly increases the reliability of the inverter and simplifies its maintenance. There is a single control unit (UC11 G2) which can control up to 5 UP11s G2.

The UP11s and UC11 G2 are supplied trough a power supply of +24 Vdc. Figure 2.1 on page 2-5 shows a general diagram of the inverter, considering the configuration with three UP11s connected in parallel.

The control of the power units is done by the UC11 G2 control unit. The control unit contains the control rack of the CFW-11 line and the ICUP board. This board sends signals to all UP11 G2 (PWM, control signals, etc.), and it receives signals from them (current, voltage feedback, etc.).

3.2 ELECTRICAL INSTALLATION

DANGER!

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

DANGER!

Les informations suivantes constituent uniquement un guide pour une installation correcte. Respectez les réglementations locales en vigueur pour les installations électriques.

DANGER!

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

DANGER!

Vérifiez que l'alimentation secteur CA est débranchée avant de commencer l'installation.

Installation and Connection

ATTENTION!

The CFW-11M G2 can be connected in circuits with symmetrical short circuit capability up to 100000 A

(480 V/690 V maximum).

rms

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.

3. 2 .1 Input Rectifier

It is necessary to use a rectifier to generate DC voltage for the power supply of the UP11 G2. The rectifier may be an Active Front End (AFE) or a diode bridge rectifier with 6, 12, 18 pulses or more.

The following items contain general directions on the sizing of a 6-pulse rectifier. For further information on multipulse rectifiers or AFE solution, contact WEG.

3. 2 .1.1 Sizing

The main rectifier bridge is selected to comply with the nominal power of the drive. The heat dissipation caused by losses at the rectifier bridge should be taken into account for the sizing of the heatsink, as well as in the heating up of the panel internal air.

ATTENTION!

The diodes reverse voltage must be ≥ 2200 V.

3.2.1.2 Line Reactor

The diode rectifier plus the capacitor bank of the UP11 G2 drain from the electric grid a current with non-sinusoidal wave shape containing harmonics of the fundamental frequency. Those harmonic currents flowing on the impedances of the power supply line cause harmonic voltage drops, distorting the supply voltage of the inverter itself and other loads connected to this line. These harmonic current and voltage distortions may increase the electrical losses in the installation, overheating components (cables, transformers, capacitor banks, motors, etc.), as well as a lowering power factor.

CFW-11M G2 | 3-11

Installation and Connection

The harmonic input currents depend on the impedance values that are present in the rectifier input/output circuit. The addition of a line reactor and/or DC bus choke reduces the current harmonic content, providing the following advantages:

 Increased input power factor.

 Reduced RMS input current.

 Reduced power supply voltage distortion.

 Increased life of the DC Link capacitors.

To determine the line reactor needed to obtain the desired voltage drop, use equation below:

Voltage Drop [%] x Line Voltage [V]

line

3 x 2π x Line Freq [Hz] x Rated Cur . [A]

ATTENTION!

It is recommended a line reactance of at least 3 % on the input of the 6-pulse diode rectifier.

3. 2 .1.3 Pre-Charge

The resistors of the pre-charge circuit must be sized according to the following criteria:

 Maximum voltage.

 Maximum energy.

 Power overload capacity of the resistors during the pre-charge period (energy dissipation capacity).

Table 3.5: Dimensioning of the pre-charge

Peak Current During the Pre-charge (A) 0.82.(V

Energy Stored in the Capacitor Bank (J)

Duration of the Pre-charge (s)

UP11- 01 G2 N.0.006.V

UP11- 02 G 2 0.031.N.R

UP11- 01 G2 0.015.N.R

Where R is the ohmic value of the resistor used on each phase and N the number of power units.

Example:

At a drive composed by three power units, whose line voltage at the input of the rectifier was 690 Vrms (UP11-01 G2), the obtained values would be the following:

 Energy stored in the capacitor bank: 3.0,006.6902 = 8569.8 J.

/R)

line

 Using three 10 Ω resistors (one per phase), each resistor must withstand 2856.6 J.

 The resistor manufacturer is able to inform the power supported by the component.

 The peak current during the pre-charge would be 56.6 A and the length of the pre-charge would be 0.45 s.

Figure 3.15: Pre-charge circuit example

The CFW-11M G2 input rectifier can be supplied through a contactor or a motorized circuit breaker (represented by K1), whose command must be interlocked with the pre-charge contactor K(PCR) command. The Figure 3.15

on page 3-13 presents an example of the recommended pre-charge circuit for the CFW-11M G2 inverter, with

simplified power and command diagrams. The digital relay output DO1 of the CC11 board must be configured with the “Pre-Charge OK” function (P0275 = 25). This relay must be used to command the pre-charge contactor and the main contactor (motorized circuit breaker). Furthermore, the pre-charge length must be timed for the protection of the auxiliary circuit (resistors, rectifier bridge). This function is carried out by a timer with a normallyclosed on-delay contact, represented in Figure 3.15 on page 3-13 by RT1.

valid for the following condition:

 Short circuit current of the transformer of 100000 symmetric Arms.  Line reactance of 3 %.

3.2.2 Busbars

The panel busbars must be sized according to the rectifier output current and the drive output current. It is recommended to use copper busbars. In case it is necessary to use aluminum busbars, it is necessary to clean the contacts and use anti-oxidant compound. If the compound is not used, any copper and aluminum joint will undergo accelerated corrosion.

3.2.3 Fuses

It is recommended to use proper fuses for operation in direct current on the DC power supply of the UP11 G2. The maximum voltage on the DC link on the UP11-01 G2 is 1200 Vdc, on the UP11-02 G2 is 800 Vdc (tripping level of the IGBTs for overvoltage). Fuses used in AC lines can be used, but the specified AC voltage must be derated. To obtain the derating factor, refer to the fuse manufacturer.

Examples of fuses:

 UP11-01 G2: PC73UD13C630TF (Mersen).

 UP11-02 G2: PC73UD12C900TF (Mersen).

3.2.4 General Wiring Diagram

For a better current distribution between the UP11, it is recommended that their output connections be interconnected through a single paralleling busbar. The length of the cables between the UP11 and the paralleling busbar must be as short as possible.

ATTENTION!

The output cables U, V and W of all paralleled UP11 must have the same length.

CFW-11M G2 | 3-21

Installation and Connection

ATTENTION!

The motor cables must be distributed as evenly as possible on the connection to the paralleling busbar, as in the example shown in Figure 3.26 on page 3-22. Distance "L" must be kept constant.

3.2.6 Input Connections

DANGER!

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).

DANGER!

Montez un dispositif de coupure sur l'alimentation du variateur. Ce composant déconnecte l'alimentation du variateur si cela est nécessaire (ex. pendant l'entretien et la maintenance).

3-22 | CFW-11M G2

Installation and Connection

ATTENTION!

A contactor or another device that frequently disconnects and reapplies the AC supply to the inverter, in order to start and stop the motor, may cause damage to the inverter power section. The drive is designed to use control signals for starting and stopping the motor. If used for that purpose, the input device must not exceed one operation per minute; otherwise, the inverter may be damaged.

ATTENTION!

The supply voltage must not exceed the inverter rated values (see Table 8.1 on page 8-2).

The interconnection between the DC Link and each UP11 G2 can be done with flat braided cables according to the Figure 3.27 on page 3-23, example, sized to withstand the DC Link current, according to the Table 8.1 on

page 8-2. The Figure 3.28 on page 3-23 shows an example of flexible braid used by WEG, using a fuse on

DC+ and another on DC-.

Installation and Connection

3.2.7 Output Connections

ATTENTION!

The inverter has an electronic motor overload protection that must 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 on the CFW-11M G2 complies with IEC609047-4-2 and

UL508C, notice the information below:

 Trip current equal to 1.25 times the motor rated current (P0401) set on the "Oriented Start-up" menu.  The maximum value of parameter P0398 (Motor Service Factor) is 1.15.  Parameters P0156, P0157 and P0158 (overload current at 100 %, 50 % and 5 % of the rated speed,

respectively) are automatically set when parameters P0401 (motor rated current) and/or P0406 (motor cooling) are set on the "Oriented Start-up" menu. If parameters P0156, P0157 and P0158 are manually set, the maximum value allowed is 1.05 x P0401.

ATTENTION!

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

Use two parallel cables with the gauge indicated in Table 3.8 on page 3-16 to interconnect connections U, V and W of the UP11 with the paralleling busbar (motor connection).

ATTENTION!

Cables U, V and W of all phases of all paralleled UP11 must have the same length so as to prevent current imbalance.

The characteristics of the cable used to connect the motor to the inverter, as well as its routing, are extremely important to avoid electromagnetic interference in other equipment and not to affect the life cycle of windings and bearings of the controlled motors.

Recommendations for motor cables:

Unshielded Cables:

 They can be used when it is not necessary to comply with the European electromagnetic compatibility directive

(2014/30/EU).

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

Table 3.9 on page 3-24.

 The emission of the cables can be reduced by installing them within a metallic conduit, which must be grounded

at least at both ends.

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

3-24 | CFW-11M G2

Installation and Connection

NOTE!

The magnetic field created by the current circulation in these cables may induce currents in nearby metal parts, heating them, and cause additional electrical losses. Therefore, keep the three cables (U, V, W) always together.

Shielded Cables:

 They are mandatory when it is necessary to comply with the electromagnetic compatibility directive (89/336/

EEC), as defined by EN 61800-3 “Adjustable Speed Electrical Power Drive Systems”. It mainly acts reducing the electromagnetic radiation disturbance produced by the motor cables in the radio frequency band.

 Regarding the installation types and details, follow the recommendations of IEC 60034-25 “Guide For Design

and Performance of Cage Induction Motors Specifically Designed For Converter Supply”; see summary in Figure

3.29 on page 3-25. Refer to the standard for further details and occasional changes related to the new revisions.

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

Table 3.10 on page 3-25.

 The grounding system must 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 parasite currents among the equipments connected to the ground, resulting in electromagnetic interference problems.

Note: (1) SCu = copper or aluminum external shield. (2) AFe = galvanized steel or iron. (3) PE = ground conductor. (4) Cable shielding must be grounded at both ends (inverter and motor). Use 360º connections for low impedance to high frequencies. (5) For using the shield as a protective ground, it must 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 must be at least 10 % of the phase power cable conductivity.

DANGER!

Do not share the grounding wiring with other equipment that operate with high currents (e.g. high power motors, soldering machines, etc.).

DANGER!

Ne pas partager le câblage de mise à la terre avec d’autres équipements opérant avec des intensités élevées (par ex: moteurs haute puissance, postes de soudure, etc.).

CFW-11M G2 | 3-25

Installation and Connection

ATTENTION!

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

DANGER!

The inverter must be obligatorily connected to a protective ground (PE). Observe the following:

 Connect the grounding points of the inverter to a specific grounding rod, or specific grounding

point or to the general grounding point (resistance ≤ 10 Ω).

 Use a minimum cable gauge for connection to the ground as indicated in Table 3.11 on page 3-26.

If local standards require different gauges, they must be observed.

 For compatibility with IEC 61800-5-1 standard, use at least one copper cable of 10 mm

to connect

the inverter to the protective earth, since the leakage current is higher than 3.5 mA AC.

DANGER!

Le variateur doit être raccordé à une terre de protection (PE). Observer les règles suivantes:

 Connectez la masse du variateur à une barre collectrice de terre en un seul point ou à un point

commun de raccordement à la terre (impédance ≤ 10 Ω).

 Utilisez la section minimale de raccordement à la terre indiquée dans les Table 3.11 on page 3-26.

Se conformer aux à la règlementation locale et/ou aux codes de l'électricité si une autre épaisseur de fil est nécessaire.

 Pour assurer la conformité avec la norme CEI 61800-5-1, connecter le variateur à la terre grâce à

un câble en cuivre à un conducteur ayant une épaisseur de fil minimale de 10 mm², étant donné que le courant de fuite est supérieur à 3,5 mA C.A.

Use the cables with the gauge indicated in Table 3.11 on page 3-26 to ground the UP11 power units.

3. 2 .11 Dynamic Braking

The braking torque obtained by the application of frequency inverters without dynamic 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 regenerated energy in excess is dissipated in a resistor mounted outside the inverter.

This kind 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.

ATTENTION!

For the CFW-11M G2, use the DBW-04 braking module only. For further information, refer to the manual of the accessory.

3.2.12.4 Typical Control Connections

Control connection 1 - Run/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 FIRST TIME POWER-UP

AND START-UP on page 5-1.

Control connection 2 - Wire Run/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 HMI key

to remote mode (local mode is default).

3.3 SAFETY STOP FUNCTION

The CFW11MG2...O...Y... inverters have the SRB board that provides the Safety Stop function. Through this board it is possible to control two safety relays (K1 and K2) which act directly on the power circuit, more specifically on the power supply of the IGBT activation fiber optics. The safety relays ensure that the IGBTs remain turned off when the Safety Stop function is activated, even in case of only one internal fault. The position of the SRB boards and terminals XC25 (Safety Stop control terminals) on the inverter is shown in Figure 3.47 on page 3-42.

The Safety Stop function prevents the accidental start of the motor.

SRB Board

XC25

DANGER!

The activation of the Safety Stop function does not ensure the electrical safety of the motor terminals (which are not isolated from the power supply in such condition).

DANGER!

L'activation de la fonction d'arrêt de sécurité ne garantit pas la sécurité électrique des bornes du moteur (elles ne sont pas isolées de l'alimentation électrique dans cet état).

ATTENTION!

In case of a multiple fault in the power stage of the inverter, the motor shaft can rotate up to 360/ (number of poles) degrees even with the activation of Safety Stop function. That must be considered in the application.

NOTE!

Inverter Safety Stop function is only one component of the safety control system of a machine and/or process. When inverter and its Safety Stop function is correctly used and with other safety components, it’s possible to fulfill the requirements of standard EN 954-1 / ISO 13849-1, Category 3 (machine safety) and IEC/EN 61508, SIL2 (safety control/signaling applied to processes and systems).

Inverter Behavior

Inverter remains in STO state and does not accept commands. In order to escape this condition, it’s required to have STO1 = 1 and STO2 = 1 simultaneously

Inverter is tripped by F160 fault (Safety Stop function related fault). To escape this condition, it’s required to reset the inverter

This function must not be used as control to start and/stop the inverter.

It’s applied voltage to relay K1 coil (STO1) but it’s not applied voltage to relay K2 coil (STO2) or vice-versa or there is a delay of more than 100 ms between one signal and the other. To solve it, correct the external circuit that generates STO1 and STO2 signals

3.3.2.3 Indication of STO Status

State of the inverter is shown on the left upper side of the display and in parameter P0006.

Possible states of the inverter: ready, run (inverter enabled), undervoltage, fault, self-tuning, configuration, DC braking and STO (Safety Stop function activated).

It’s possible to set one or more digital and relay outputs of the inverter to indicate that Safety Stop function is activated (state of the inverter = STO), if the inverter is or not on a fault state and more specifically if the inverter was tripped by F160 fault (Safety Stop function fault). For that use the parameters P0275 (DO1), P0276 (DO2), P0277 (DO3), P0278 (DO4) and P0279 (DO5) according to Table 3.25 on page 3-44.

Installation and Connection

3.3.2.4 Periodical Test

Safety Stop function, alternatively safety stop inputs (STO1 and STO2), must be activated at least once a year for preventive maintenance purposes. Inverter power supply must be switched off and then on again before carrying out this preventive maintenance. If during testing the power supply to the motor is not switched off, safety integrity is no longer assured for the Safety Stop function. The drive must therefore be replaced to ensure the operational safety of the machine or of the system process.

Installation and Connection

Circuit operation of SS1 function from Figure 3.48 on page 3-45:

In this case, when the activation command is given to the external safety relay, safety relay opens inverter DI2 signal (via terminals 23 to 24) and motor is decelerated first by the inverter (via deceleration ramp). When the time delay set at the external safety relay expires (this delay must be higher than required time to stop the motor, taking into account deceleration time set on the inverter and inertia of the motor load), the safety relay delayed contacts (terminals 47 to 48 and 57 to 58) opens inverter STO1 and STO2 signals and the inverter Safety Stop function is activated. The motor stops according to category 1 (SS1) of standard IEC/EN 60204-1.

In order to drive the motor again, it is required to apply STO1 and STO2 signals again (to close terminals 13 to 23 and 23 to 24) and apply a pulse on inverter DI1 input (START).

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 on page 5-4, first modifying parameter P0317 to 1 and then, setting all remaining parameters as they are prompted in the display.

5.5 HOW TO CONNECT A PC

NOTE!

 Always use standard host/device shielded USB cable. Cables without shield may cause

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.

5-8 | CFW-11M G2

First Time Power-Up and Start-Up

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 on the PC.

2. Connect the PC to the inverter via USB cable.

3. Start the SuperDrive G2.

4. Select “Open” and the files stored on the PC are shown.

5. Select the proper file.

6. Use the function "Write Parameters to the Drive".

All parameters are now transferred to the inverter.

For further details and other functions related to the SuperDrive G2, refer to the Manual of the SuperDrive.

5.6 FLASH MEMORY MODULE

Location according to Figure 5.5 on page 5-9.

Flash Memory Module

Figure 5.5: Detail of location of the ﬂash memory module

Features:

 Store a copy of the inverter parameters.

 Transfer parameters stored in the FLASH memory to the inverter.

 Transfer firmware stored in the FLASH memory to the inverter.

 Store programs created by the SoftPLC.

CFW-11M G2 | 5-9

First Time Power-Up and Start-Up

Whenever the inverter is powered up, this program is transferred to the RAM memory located in the inverter control board and executed.

Refer to the CFW-11 programming manual and to SoftPLC manual for further details.

ATTENTION!

Before installing or removing the FLASH memory module, disconnect the inverter power supply and wait for the complete discharge of the capacitors.

5.7 OPERATION WITH A REDUCED NUMBER OF POWER UNITS

The CFW-11M G2 can operate with a reduced number of UP11 and reduced power for a short time. That operating mote is called "Reduced Power Mode". It may be applied to critical processes in which you do not want to stop a whole machine when one UP11 fails, enabling the operation with reduced power until you have a UP11 for replacement.

The general scheme of a drive with 5 UP11 is shown in Figure 3.22 on page 3-18. The reduced power mode works as a drive of up to 2 UP11.

Assuming that in the drive of Figure 3.22 on page 3-18, composed of 5 UP11, the UP11 number4 fails. In order to reestablish the drive operation with reduced power (Reduced Power Mode), you must follow the steps below:

1. Disconnect the power supply from the drive.

2. Identify the defective UP11 (in this case, number 4).

3. Disconnect the power and control of the UP11 number 4, according to Figure 5.7 on page 5-12.

4. Move the control connections on the ICUP board, as shown in Figure 5.7 on page 5-12. Connect the control cables of UP11 number 5 to position 4 of the ICUP board. Thus, UP11 5 becomes UP11 4.

5. Configure the new number of UP11 through DIP switch S2 located on the ICUP board, according to Table

3.17 on page 3-32.

6. Change DIP switch S1:4 to ON; thus, it will be informed to the control that the CFW-11M G2 drive is operating with a reduced number of UP11.

ATTENTION!

It is recommended that the drive operate short of one UP11 at most.

7. Reconnect only the power supply of the drive control.

8. Alarm A420 will be indicated (Reduced Power Mode), informing that the CFW-11M G2 is operating in the reduced power mode.

9. Check if parameters P0295 (Rat. Curr. ND/HD Inv.) and P0296 (Rated Line Voltage) are according to the voltage and the number of connected UP11.

10. Set the following control parameters:

11. P0169: Maximum Torque Current +.

12. P0170: Maximum Torque Current -.

13. Parameters P0169 and P0170 must be set so that the maximum torque current will not exceed the maximum inverter current. The values of those parameters are referenced to the motor rated current, as you can see in Item 11.8.6 - Torque Current Limit of the CFW-11 programming manual.

5-10 | CFW-11M G2

14. Connect the drive power source.

Troubleshooting and Maintenance

6.5 PREVENTIVE MAINTENANCE

DANGER!

 Always turn off the main power supply before touching any electrical component associated to

the inverter.

 High voltages may still be present even after disconnecting the power supply.  To prevent electric shock, wait at least 10 minutes after turning off the input power for the complete

discharge of the power capacitors.

 Always connect the equipment frame to the protective ground (PE). Use the adequate connection

terminal at the inverter.

DANGER!

 Débranchez toujours l'alimentation principale avant d'entrer en contact avec un appareil électrique

associé au variateur.

 Des tensions élevées peuvent encore être présentes, même après déconnexion de l’alimentation.  Pour éviter les risques d’électrocution, attendre au moins 10 minutes après avoir coupé l’alimentation

d’entrée pour que les condensateurs de puissance soient totalement déchargées.

 Raccordez toujours la masse de l'appareil à une terre protectrice (PE). Utiliser la borne de connexion

adéquate du variateur.

ATTENTION!

The electronic boards have electrostatic discharge sensitive components. Do not touch the components or connectors directly. If necessary, first touch the grounded metallic frame or wear a ground strap.

Do not perform any withstand voltage test!

If necessary, consult WEG.

The inverters require low maintenance when properly installed and operated Table 6.3 on page 6-12 presents the main procedures and time intervals for preventive maintenance. Table 6.4 on page 6-13 contains the recommended inspections to be performed every 6 months after the start-up.

Table 6.3: Preventive maintenance

Maintenance Interval Instructions

Keypad battery replacement Every 10 years See Chapter 4 HMI on page 4-1

Fan replacement After 50.000 hours of operation

(1) The inverters are programmed at the factory for automatic control of the fans (P0352 = 2) so that they only start when the temperature of the heatsink increases. Therefore, the number of operating hours of the fans will depend on the operating conditions (motor current, output frequency, temperature of the cooling air, etc.). The inverter records in parameter P0045 the number of hours that the fan remained ON. When the fan reaches 50.000 hours of operation, the HMI display will show alarm A177.

7.1 SAFETY STOP FUNCTION

Inverters with the following codification CFW11MG2...O...Y.... Refer to Section 3.3 SAFETY STOP FUNCTION on

page 3-42.

7.2 ACCESSORIES

The accessories are installed on the inverters easy and quickly using the “Plug and Play” concept. When an accessory is connected to the slots, the control circuit identifies the model and informs the code of the accessory connected in P0027 or P0028. The accessory must be installed with the inverter power supply disconnected.

Part number and model of each available accessory are presented in Table 7.1 on page 7-1. The accessories can be ordered separately and will be shipped in individual packages containing the components and the manual with detailed instructions for the product installation, operation, and programming.

ATTENTION!

Only one module at a time can be fitted into each slot (1, 2, 3, 4 or 5).
