2.3 ABOUT THE CFW-11

The CFW-11 is a high performance variable frequency drive that makes it possible the control of speed and torque of three-phase AC induction motors. The central characteristic of this product is the "Vectrue" technology, which presents the following advantages:

(V/f), V VW or vector control programmable in the same product.

The vector control can be programmed as "sensorless" (which means standard motors, without the need of

encoder) or vector control with motor encoder.

The "sensorless" vector control allows high torque and fast response, even at very slow speeds or during

starting.

The "vector control with encoder" allows very high speed accuracy and control for the entire speed range

(speed control down to 0 rpm).

The "Optimal Braking" function for the vector control allows a controlled motor braking, eliminating in some

applications the braking resistor.

The vector control "Self-Tuning" function allows the automatic setting of the regulators and control parameters,

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

Page 25

General Information

CFW-11 | 2-15

2.6 RECEIVING AND STORAGE

The CFW-11 inverters from the frame sizes F, G and H models are supplied packed in wooden boxes.

There is an identification label affixed to the outside of the package, identical to the one affixed to the side of the inverter CFW-11.

To open the package:

1. Remove the package front cover.

2. Take out the polystyrene foam protection.

Verify whether:

1. The CFW-11 nameplate corresponds to the purchased model.

2. Any damage occurred during transportation.

If any problems are detected, contact the carrier immediately.

If the CFW-11 is not installed soon, store it in a clean and dry location (temperature between -25 °C and 60 °C (-13 °F and 140 °F)), with a cover to prevent dust accumulation inside it.

ATTENTION!

When the inverter is stored for a long period, it becomes necessary to perform the capacitor reforming. Refer to the procedure in the Section 6.5 PREVENTIVE MAINTENANCE on page 6-9 on Table 6.3

on page 6-9.

3 INSTALLATION AND CONNECTION

This chapter describes the CFW-11 electrical and mechanical installation procedures. The guidelines and suggestions must be followed aiming personnel and equipment safety, as well as the proper operation of the inverter.

3.1 MECHANICAL INSTALLATION

3.1.1 Environmental Conditions

NOTE!

The inverter are designed for indoor use only.

Avoid:

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 (standard conditions (surrounding the inverter), no frost allowed):

- 10 °C to 45 °C (50 °F to 113 °F) for frame sizes F and G (except models 720 A and 760 A).

- 10 °C to 40 °C (50 °F to 104 °F) for frame sizes G (only models 720 A and 760 A) and H.

From 40 °C to 45 °C (50 °F to 113 °F) for frame size G (only model 720 A): 2 % of current derating for each

celsius degree above maximum temperature as specified in item above.

From 40 °C to 45 °C (50 °F to 113 °F) for frame sizes G (only model 760 A) and H: 1 % of current derating

for each celsius degree above maximum temperature as specified in item above.

From 45 °C to 55 °C (113 °F to 131 °F) for frame sizes F, G and H: 2 % of current derating for each Celsius

degree above maximum temperature as specified in item above.

Maximum altitude: up to 1000 m (3.300 ft) - rated conditions.

From 1000 m to 4000 m (3.300 ft to 13.200 ft) - 1 % of current derating for each 100 m (330 ft) (or 0.3 %

each 100 ft) above 1000 m (3.300 ft) altitude.

Page 28

Installation and Connection

3-2 | CFW-11

From 2000 m to 4000 m (6.600 ft to 13.200 ft) above sea level - derating of maximum voltage of 1.1 %

for each 100 m (330 ft) above 2000 m (6.600 ft).

Humidity: from 5 % to 95 % non-condensing.

Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution. Condensation

shall not originate conduction through the accumulated residues.

3.1.2 Positioning and Mounting

Consult the inverter weight at the Table 8.1 on page 8-2, Table 8.2 on page 8-3 and Table 8.3 on page

8-5.

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 on page 3-3. Refer to the Section

8.5 MECHANICAL DATA on page 8-8 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 Figure 3.2 on

page 3-4.

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

on page 3-4) and provide an air deflecting plate so that the heat rising up from the bottom inverter

does not affect the top inverter.

ATTENTION!

Provide conduit for physical separation of the signal, control, and power conductors (refer to Section

3.2 ELECTRICAL INSTALLATION on page 3-8).

3.1.3 Cabinet Mounting

It is possible to mount the inverters in two manners, either on the mounting surface, or with the heatsink mounted outside the cabinet, so that the air for cooling the power heatsink is kept outside the enclosure (flange mounting). For these cases, consider:

Surface mounting:

Provide adequate exhaustion, so that the internal cabinet temperature remains within the allowed range for

the inverter operation conditions.

The power dissipated by the inverter at its rated condition, as specified in Table 8.1 on page 8-2 in the

column "Power dissipated in watts, surface mount".

Cooling air flow according to the Table 3.1 on page 3-5.

The position and diameter of the mounting holes according to the Figure 3.1 on page 3-3.

Flange mounting:

ATTENTION!

The part of the inverter that stays outside the cabinet is rated IP20. See Section 8.2 ELECTRONICS/

GENERAL DATA on page 8-6.

The power specified in Table 8.1 on page 8-2 will be dissipated inside the cabinet. The other losses (power

modules) will be dissipated at the external ventilation duct.

The inverter mounting supports and the hoisting eyes must be removed. Refer to the Figure 2.4 on page

2-10, positions I and J.

Dimensions of the flange-mounting opening and the diameters of the securing holes must be according to

the Figure 3.1 on page 3-3.

3.2.2 Power/Grounding Wiring and Fuses

ATTENTION!

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

ATTENTION!

Sensitive equipment such as PLCs, temperature controllers, and thermocouple cables, must be kept at a minimum distance of 0.25 m (9.84 in) from the frequency inverter and from the cables connecting the inverter to the motor.

DANGER!

Wrong cable connections:

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

- Check all the connections before powering up the inverter.

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

DANGER!

Mauvaise connexion des câbles:

- Le variateur sera endommagé si l’alimentation d’entrée est connectée aux bornes de sortie (U/T1, V/T2 ou W/T3).

- Vérifier toutes les connexions avant de mettre le variateur sous tension.

- En cas de remplacement d’un variateur existant par un CFW-11, vérifier si l’installation et le câblage sont conformes aux instructions figurant dans ce manuel.

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.), RCD nuisance trips may occur. Contact the RCD manufacturer for selecting the most appropriate device to be used with inverters.

NOTE!

The wire gauges listed in the Table 3.2 on page 3-13 are orientative values. Installation conditions and the maximum permitted voltage drop must be considered for the proper wiring sizing.

Input fuses:

The fuse to be used in the input must be of the UF type (Ultra-Fast) with I²t equal to or smaller than the

specified in Table 3.2 on page 3-13 (consider the cold current extinction value (not the melting value) to protect the input rectifier diodes of the inverter and wiring.

Page 39

Installation and Connection

CFW-11 | 3-13

Optionally, slow blow fuses can be used at the input. They must be sized for 1.2 x the inverter rated input

current. 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.

3.2.3.1 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).

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 power supply that feeds the inverter must have a grounded neutral. In case of IT networks, follow the instructions described in Item 3.2.3.1.2 IT Networks on page 3-22.

NOTE!

The input power supply voltage must be compatible with the inverter rated voltage.

NOTE!

Power factor correction capacitors are not needed at the inverter input (R, S, T) and must not be installed at the output (U, V, W).

NOTE!

For models with special DC hardware an external pre-charge circuit must be provided. For further information, refer to the manufacturer.

3.2.3.1.2 IT Networks

ATTENTION!

To use frame sizes F, G and H inverters in IT networks (neutral ungrounded or grounded through a high ohmic value resistor), or in corner-grounded delta networks, it is necessary to disconnect the cable with the ring tongue lug from the ground busbar and connect it to the isolated point on the power terminal block, as showed in the Figure 3.11 on page 3-23 and Figure 3.12 on page 3-23. This is necessary to avoid damages when operating with a line input short circuited with the ground.

NOTE!

The ground-fault protection (F074) is intended for IGBT protection and may not be activated when inverter output is shorted to ground, when fed by IT networks. External insulation monitoring devices should be used for system fault monitoring.

3.2.3.2 Dynamic Braking

ATTENTION!

Frame sizes F, G and H models do not have internal braking IGBT. When necessary, braking modules and external resistors should be installed, as shown in Figure 3.13 on page 3-24.

NOTE!

Set P0151 and P0185 to the maximum value (800 V) when using dynamic braking.

The braking torque that can be obtained using frequency inverters without dynamic braking varies between 10 % to 35 % of the motor rated torque.

In order to obtain higher braking torques, resistors for dynamic braking must be used. In this case, the energy regenerated in excess is dissipated on a resistor mounted outside the inverter.

Page 50

Installation and Connection

3-24 | CFW-11

This type of braking is used in cases when 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.

3.2.3.3 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 in the CFW-11 is in accordance with the IEC60947-4-2 and UL508C standards, note the following information:

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

menu.

The maximum value for 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 adjusted when parameters P0401 (Motor Rated Current)

and/or P0406 (Motor Ventilation) are adjusted in the oriented start-up routine. If parameters

P0156, P0157 and P0158 are manually adjusted, the maximum allowed value 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.

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:

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

(2014/30/EU).

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

the Table 3.6 on page 3-27.

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

at both ends.

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

Page 52

Installation and Connection

3-26 | CFW-11

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:

Are mandatory when the electromagnetic compatibility directive (2014/30/EU) has to 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.

Regarding to the types and installation details, follow the recommendations of IEC 60034-25 "Guide for

Design and Performance of Cage Induction Motors Specifically Designed for Converter Supply", verify the summary in the Figure 3.14 on page 3-27. 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

the Table 3.6 on page 3-27.

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.

3.2.4 Grounding Connections

DANGER!

Do not share the grounding wiring with other equipment that operate with high currents (e.g. high power motors, soldering machines, etc.). When installing several inverters, follow the procedures presented in Figure 3.15 on page 3-29 for the grounding connection.

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.). Lors de l’installation de plusieurs variateurs, appliquer les procédures présentées dans l’illustration Figure 3.15 à la page 3-29 pour la connexion de mise à la terre.

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:

- Use a minimum wire gauge for ground connection equal to the indicated in the Table 3.2 on

page 3-13 or Table 3.3 on page 3-16. 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 mAac.

DANGER!

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

- Utilisez la section minimale de raccordement à la terre indiquée dans les Table 3.2 à la page

3-13 or Table 3.3 à la page 3-16. Se conformer aux à la règlementation locale et/ou aux codes

de l'électricité si une autre épaisseur de fil est nécessaire.

- 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).

- 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.

Follow instructions below for the proper installation of the control wiring:

1. Wire gauge: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).

2. Maximum tightening torque: 0.5 N.m (4.50 lbf.in).

3. Use shielded cables for the connections at XC1 and run the cables separated from the remaining circuits (power, 110 V / 220 Vac control, etc.), as presented in Table 3.8 on page 3-34. If control cables must cross other cables, it must be done perpendicularly among them, keeping a minimum of 5 cm (1.9 in) distance at the crossing point.

5. Relays, contactors, solenoids or coils of electromechanical brakes installed close to the inverter may occasionally generate interferences in the control circuitry. To eliminate this effect, RC suppressors (with AC power supply) or freewheel diodes (with DC power supply) must be connected in parallel to the coils of these devices.

3.2.6 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 - 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

LOC

REM

(local mode is default). Set P0220 = 3 to change the default setting of HMI key

3.3 SAFETY STOP FUNCTION

The inverters CFW11...O...Y... have the board SRBXX that implements Safety Stop function. Through this board it is possible to control two safety relays (K1 and K2) that actuate directly on the power circuit, more specifically on the IGBTs gate drivers power supply. The basic functional block diagram is shown in Figure 3.25 on page 3-39.

The safety relays guarantee that the IGBTs remain switched off when Safety Stop function is activated, even in case of an internal single failure. The position of SRBXX board and XC25 terminals (Safety Stop control terminals) on the inverter is shown in Figure 3.18 on page 3-33.

The Safety Stop function prevents the motor starting accidentally.

DANGER!

The activation of the Safety Stop function does not guarantee electrical safety of the motor terminals (they are not isolated from the power supply in this 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).

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 STO Status Indication

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 3.13 on page 3-42.

3.3.2.4 Periodic 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.

DI1 and DI2 inputs set as 3-wire start/stop commands

Circuit operation of SS1 function from Figure 3.26 on page 3-43:

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.

5.2.2 Oriented Start-Up

There is a group of parameters named "Oriented Start-up", which makes the inverter settings easier. The parameter P0317 from this group allows entering the Oriented Start-up routine.

The Oriented Start-Up routine presents the main parameters on the HMI in a logical sequence, so that their setting, according to the operation conditions, prepares the inverter for the operation with the used line and motor.

In order to enter an Oriented Start-up routine, follow the sequence presented in Figure 5.2 on page 5-5, first changing P0317 = 1, and then setting the other parameters as they are displayed on the HMI.

Page 82

5.2.3 Basic Application Parameter Settings

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, whose setting is necessary in the majority of cases. To make this task easier, there is a group named Basic Application. A summary of the parameters contained in this group is presented in the Table 5.1 on page 5-7. Also a group of read-only parameters shows the value of the most important inverter variables such as voltage, current, etc. The main parameters contained in this group are listed in Table 5.2 on page 5-8. For further details, refer to the CFW-11 programming manual.

Follow steps outlined in Figure 5.3 on page 5-6 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.

6 TROUBLESHOOTING AND MAINTENANCE

This chapter presents:

- A lists of all the faults and alarms that may occur.

- The possible causes of each fault and alarm.

- A lists of the most frequent problems and corrective actions.

- Instructions for periodic inspections and preventive maintenance

on the equipment.

6.1 OPERATION OF FAULTS AND ALARMS

When a fault is detected (FXXX) is detected:

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 data is saved in the control circuit EEPROM memory:

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

- The "FAULT" or alarm potentiometer 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).

For the inverter to return to normal operation right after the occurrence of a fault, it is necessary to reset it, which can be done as follows:

Removing the power supply and reapplying it (power-on reset).

Pressing the HMI key (manual reset).

Through the "Reset" soft key.

Automatically by setting P0340 (auto-reset).

Through a digital input: DIx = 20 (P0263 to P0270).

The "STATUS" LED changes to yellow.

The PWM pulses are not blocked (the inverter remains operating).

6.2 FAULTS, ALARMS, AND POSSIBLE CAUSES

Table 6.1 - Faults, alarms and possible causes

Fault/Alarm Description Possible Causes

F006

Imbalance or Input Phase Loss

Mains voltage imbalance too high or phase missing at the input power supply.

Note:

- If the motor is unloaded or operating with reduced load, this fault may not occur.

- Fault delay is set at parameter P0357. P0357 = 0 disables the fault.

Phase missing at the inverter input power supply. Input voltage imbalance > 5 %. Pre-charge circuit fault.

F021

DC Bus Undervoltage

DC bus undervoltage condition occurred.

The input voltage is too low and the DC bus voltage

dropped below the minimum permitted value (monitor the value at Parameter P0004): Ud < 385 V - for supply voltage 380 V (P0296 = 1). Ud < 405 V - for supply voltage 400-415 V (P0296 = 2). Ud < 446 V - for supply voltage 440-460 V (P0296 = 3).

Ud < 487 V - for supply voltage 480 V (P0296 = 4). Phase loss at the input power supply. Pre-charge circuit failure. Parameter P0296 was set to a value above the power

supply rated voltage.

F022 DC Bus Overvoltage

DC bus overvoltage condition occurred.

The input voltage is too high and the DC bus voltage

surpassed the maximum permitted value:

Ud > 800 V - for 380-480 V models (P0296 = 1, 2, 3 or 4). Inertia of the driven-load is too high or deceleration time

is too short. Parameters P0151 or P0153 or P0185 set to high.

F030

Power Module U Fault

Power Module U IGBTs desaturation.

Short-circuit between motor phases U and V or U and W.

F034

Power Module V Fault

Power Module V IGBTs desaturation.

Troubleshooting and Maintenance

CFW-11 | 6-9

6.5 PREVENTIVE MAINTENANCE

DANGER!

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

the inverter. High voltage 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. The Table 6.3 on page 6-9 presents the main procedures and time intervals for preventive maintenance. The Table 6.4 on page 6-10 provides recommended periodic inspections to be performed every 6 months after the inverter start-up.

Section 2.4 CFW-11 IDENTIFICATION LABELS on page 2-12)

Apply power to the inverter (voltage between 220 and

230 Vac, single-phase or three-phase, 50 or 60 Hz) for

at least one hour. Then, disconnect the power supply

and wait at least 24 hours before using the inverter

(reapply power)

Every 10 years Contact WEG technical support to obtain replacement

procedures

(1) The inverters are set at the factory 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 fan operating hours in the parameter P0045. When this parameter reaches 50000 operating hours, the keypad display shows the alarm A177. (2) Valid for frame sizes F and G only.
