2.3 ABOUT THE CFW-11M G2 RB AND CFW-11W G2 RB

The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters are the second generation of the CFW-11M RB and CFW-11W RB regenerative frequency converter line respectively. The main differences in relation to the previous generation are the following:

 Smaller. The CFW-11M G2 RB is shorter and slimmer than the CFW-11M RB, allowing the installation of three

UP11 G2 RB in a panel with columns 800 mm wide and 2000 mm high. The CFW-11W G2 RB is shorter, slimmer and less deep than the CFW-11W RB, allowing the installation of three UP11W G2 in a panel with columns 800 mm wide, 2000 mm high and 600 mm deep.

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

The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters are high-performance products that enable the rectification of three-phase lines with the following advantages:

 Low harmonic distortion in the input current.

 Capacity to return energy to the line (regeneration), enabling high braking torques.

The CFW-11M G2 RB and CFW-11W G2 RB regenerative frequency converters have a modular design, with configurations containing one to five power units (UP11 G2 or UP11W G2), one control unit (UC11RB G2) and wiring cables. The modular assembly increases the converter reliability and simplifies its maintenance. There is a single control unit (UC11RB G2) which can control up to five UP11s G2 or five UP11Ws G2.

CFW-11MW G2 RB | 2-3

General Information

The CFW-11W G2 RB regenerative frequency converter line is water cooled, being smaller than the other converters.

The UP11s, UP11Ws and UC11RB G2 are fed through an external +24 Vdc power supply. Figure 2.1 on page 2-4 and

Figure 2.3 on page 2-6 respectively show the general diagrams of the air-cooled and water-cooled converters,

considering the configuration with three UP11s connected in parallel.

The UC11RB G2 control unit controls the power units. The control unit contains the control rack of the CFW-11

line and the ICUP board. This board sends signals to all UP11 G2 or UP11W G2 (PWM, control signals, etc.), and receives signals from them (current, voltage feedback, etc.).

The bypass valve is necessary for the temperature control and protection against condensation. The diaphragm accumulator ensures a quite constant pressure in the cooling system even when great variations occur in the coolant temperature. The pump provides the continuous coolant flow; it is recommended that such pump be made of stainless steel. The acceptable differential pressure in the cooling circuit in relation to the atmosphere must not exceed 6 bar. That must be guaranteed by the over pressure valve.

ATTENTION!

The hoses that connect the cooling system to the UP11W G2 must not conduct electricity.

ATTENTION!

The acceptable differential pressure in the cooling circuit in relation to the atmosphere must not exceed 6 bar.

ATTENTION!

The cooling circuits of the UP11W G2 must not be connected in series in the cooling system circuit.

NOTE!

WEG RSW cooling system can be used for cooling the CFW11W G2 RB. For further information, refer to the RSW User's Manual.

3-18 | CFW-11MW G2 RB

Installation and Connection

The water used in the coolant must meet the specifications of Table 3.10 on page 3-19. The coolant must not contain any organic sediments or active chemical agents. The coolant is composed of demineralized water, corrosion inhibitor and ethylene glycol.

Table 3.10: Water speciﬁcation

ATTENTION!

Do not use sea or tap water in the coolant.

The specifications of the inverter output current informed in Chapter 8 TECHNICAL DATA on page 8-1 are for a coolant temperature between 10 and 45 °C (50 ºF to 113 ºF), and the composition according to Table 3.11 on

page 3-19.

µm < 300

Table 3.11: Coolant composition for temperature from 10 to 45 °C (50 ºF to 113 ºF)

Component Proportion

Demineralized water 88.5 %

Ethylene glycol 10 %

Inhibitor CorteC VpCI-649 1. 5 %

For the inverter operation at temperatures below 10 °C (50 ºF), the concentration of ethylene glycol in the coolant must be increased. The increase of the percentage of ethylene glycol reduces the coolant specific heat and the system heat exchange capacity. Therefore, if the inverter operates with a quantity of ethylene glycol above the specification of Table 3.11 on page 3-19 and coolant temperature of 45 °C (113 ºF), the output current must be derated. As the ethylene glycol concentration is normally increased to reduce the coolant freezing point, the coolant temperature reduction can compensate the current derating. Table 3.12 on page 3-19 shows the maximum percentage of the output current as a function of the ethylene glycol concentration and the coolant temperature.

Condensation may occur when the incoming water temperature is significantly lower than the ambient temperature. The water temperature to avoid condensation varies according to the air relative humidity and ambient temperature.

The temperature at which the water vapor contained in the air turns into liquid as small water drops is known as "dew point".

3.4 ELECTRICAL INSTALLATION

DANGER!

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

DANGER!

Make sure the power supply is disconnected before starting the connections.

ATTENTION!

The CFW-11M G2 RB and CFW-11W G2 RB can be connected to circuits with short-circuit capacity of up to 100000 symmetric Arms (maximum 480 V/690 V).

ATTENTION!

The short-circuit protection of the converter does not provide short-circuit protection for the feeder circuit. The short-circuit protection of the feeder circuit must be provided in accordance with the applicable local regulations.

3.4.1 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).

Installation and Connection

The power supply of the CFW-11M G2 RB or CFW-11W G2 RB regenerative frequency converters can be done via contactor or motorized circuit breaker (represented by K1), observing that its command must be interlocked with the command of the KPCR pre-charge contactor. Figure 3.28 on page 3-23 shows an example of a recommended pre-charge circuit with the simplified power and control 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). In addition, the duration of the pre-charge must be timed to protect the components of the auxiliary circuit (resistors, contactor). This function is performed by a timing relay with on-delay, represented in Figure 3.28 on page 3-23 by RT1. The KSINC contactor ensures that the synchronism circuit will only be powered after the completion of the pre-charge. The QPCR and QSINC circuit breakers protect the pre-charge and synchronism circuits respectively.

3.4.2 Busbars

The panel busbars must be sized according to the converter output current and the drive input 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 an anti-oxidant compound. If the compound is not used, any copper and aluminum joint will undergo accelerated corrosion.

3.4.3 Fuses

Fuses must be installed at the input of each power unit, that is, each power unit must be individually proteced with fuses at their input.

Ultrafast type fuses (UR) must be used at the input.

For UL conformity, use class J fuses at the converter power supply with current not above the values of

Table 3.17 on page 3-24.

: Grounding cable connection.

For a better current distribution between the UP11 G2 or UP11W, it is recommended that their output connections be interconnected through a single paralleling busbar. The length of the cables between the UP11 G2 or UP11W and the paralleling busbar must be as short as possible.

ATTENTION!

The output cables U, V and W of the UP11 G2 and UP11W G2 must have the same length.

ATTENTION!

If a busbar is used for parallelism of the power units, the filter cables must be distributed as evenly as possible in the connection to the paralleling busbar, as shown in Figure 3.37 on page 3-31. Distance "L" must be kept constant.

DANGER!

Incorrect cable connection:

 Check all the connections before energizing the converter.  In case of replacement of an existing converter by a CFW-11M G2 RB, check if all the installation

and wiring connected to it complies with the instructions of this manual.

DANGER!

Provide a disconnecting device for the converter power supply. This device must cut off the inverter power supply whenever necessary (during maintenance, for instance).

CFW-11MW G2 RB | 3-31

Installation and Connection

ATTENTION!

The supply voltage must not exceed the converter rated values (see Table 8.1 on page 8-2 and

Table 8.2 on page 8-3).

ATTENTION!

Capacitors for power factor correction must not be used at the input (U, V, W).

NOTE!

The gauges indicated in Table 3.18 on page 3-32 and Table 3.19 on page 3-33 are reference values only. For the proper wiring sizing, consider the installation conditions and the maximum permissible voltage drop.

Use two parallel cables with the gauge indicated in Table 3.18 on page 3-32 to interconnect connections U, V and W of the UP11 with the paralleling busbar (filter output).

ATTENTION!

Cables U, V and W of all phases of all UP11 G2 and UP11W G2 must have the same length to prevent current unbalance.

The characteristics of the cable used to connect the converter to the filter, as well as its interconnection and routing, are extremely important to avoid electromagnetic interference in other devices.

DANGER!

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

ATTENTION!

The neutral conductor of the line that powers up the converter must be solidly grounded; however, this conductor must not be used to ground the converter.

DANGER!

The converter must be connected to a protection grounding (PE). Observe the following:

 Connect the converter grounding points 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 3.19 on page 3-33.

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

 For compatibility with IEC 61800-5-1, use at least one 10 mm² copper cable to connect the converter

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

3.4.9 Input Filters

3.4.9.1 Basic Deﬁnitions

For the operation of the regenerative frequency converter, it is necessary to use an input filter to eliminate the circulation of high frequency currents generated by the switching of the regenerative frequency converter IGBTs on the power grid. In this manual, input filters are the components connected between the power grid and the regenerative frequency converter input.

3.4.9.2 How to Specify the Filter Model

WEG has input filters ready to be used with each of its regenerative frequency converters. To specify the model of the input filter, enter the voltage and current values into the respective smart code fields for rated supply voltage and rated input current, as in the example of Table 3.21 on page 3-35.

The CFW-11M G2 RB and the CFW-11W G2 RB monitor the line voltage (R, S and T) at the converter input by means of a synchronism board and two transformers. The signals obtained are used in the control of the regenerative frequency converter.

The synchronism circuit wiring diagram can be seen in Figure 3.28 on page 3-23. The KSINC contactor must be closed together with the main contactor K1. It is recommended to use a circuit breaker (QSINC) to protect the synchronism transformers.

The parameters related to AO1 and AO2 must also be set according to the selection of the switches and desired values.

For the correct connection of the control, use:

1. Gauge of the cables: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).

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

3. Wiring on XC1 must be done with shielded cables separated from the other wiring (power, control in 110/220V, etc.), according to Table 3.33 on page 3-48. If those cables must cross other cables, it must be done perpendicularly, keeping the minimum separation distance of 5 cm at the crossing point.

Energization and Start-Up

5 ENERGIZATION AND START-UP

This chapter explains:

 How to check and prepare the converter before energizing it.

 How to energize and check the success of the energization.

5.1 PREPARATION AND ENERGIZATION

The converter must have already been installed according to Chapter 3 INSTALLATION AND CONNECTION on

page 3-1. If the drive design is different from the typical drives suggested, the steps below may also be followed.

DANGER!

Always disconnect the general power supply before making any connections.

1. Configure DIP switch S1 located on the ICUP board, according to the rated voltage of the UP11 G2 or UP11W G2 used on the drive, Table 3.29 on page 3-43.

2. Configure the number of UP11 G2 or UP11W G2 connected in parallel through DIP switch S2 located on the ICUP board, according to Table 3.31 on page 3-43.

3. Check if the power, grounding and control connections are correct and firm.

4. Remove all the materials left inside the drive.

5. Check all grounding connections (panel, door where the control is installed, etc.).

6. In the case of UP11W G2 (water-cooled):

a. Make a pressure test on the Cooling System to check for leaks. b. Turn on the Cooling System and set the flow and the incoming water temperature according to the values

of Table 3.19 on page 3-33.

c. Keep the water flowing for five minutes and check for leaks on the hydraulic connections.

7. Energize the control (supply +24 Vdc).

8. Close the panel doors.

9. The HMI must indicate undervoltage with the electronics energized and the power units de-energized. Parameter P0004 (Voltage on the DC Link) will indicate approximately 15 Vdc.

10. Measure the voltage of the line and check if it is within the allowed range, according to Chapter 8 TECHNICAL

DATA on page 8-1.

11. Check that the automatic hardware identification has recognized the converter current properly, parameter P0295. The converter current must be compatible with the number of power units installed.

12. Set parameter P0296 according to the rated voltage of the input line.

13. Command the drive, pre-charge the link, and close the main circuit breaker/contactor.

14. Enable the PWM pulses via DI.

15. Check that the DC link voltage indicated in P0004 is close to the P0151 value.

16. Check the success of the energization.

CFW-11MW G2 RB | 5-1

Energization and Start-Up

17. The display must show the standard monitoring screen (Figure 4.3 on page 4-3 (a)), the status LED must turn on and remain on in green.

18. Follow the start-up routine of the output inverters according to the directions contained in the specific manual.

5.2 START-UP

The start-up can be simply explained in three steps, using the programming resources with the existing parameter groups Oriented Start-Up and Basic Application.

Sequence:

1. Set the password to change parameters.

2. Execution of the Oriented Start-Up routine.

3. Setting the parameters of the Basic Application group.

5.2.2 Oriented Start-up

To simplify the setting of the converter, there is a parameter group called Oriented Start-Up. Within this group is parameter P0317, which can be used to access the Oriented Start-Up.

The Oriented Start-up routine shows the main parameters on the HMI in a logical sequence, so that their setting, according to the operating conditions, prepares the inverter for operation according to the line used.

In order to enter the Oriented Start-Up routine, follow the sequence shown in Figure 5.2 on page 5-3, first changing P0317 = 1, and then setting the other parameters as they are displayed on the HMI.

The setting of the parameters displayed in this operating mode automatically changes the content of other internal variables and/or parameters of the converter.

During the Oriented Start-Up routine, the "Config" (Configuration) status will be indicated on the top left part of the HMI.

In case you want to prevent unauthorized people from changing parameters, just change the content of P0000 to a value different from 5. Follow the same procedure presented in Item 5.2.1 Password Setting in P0000 on page

5-2. To change the password, refer to P0200 in the programming manual.

5.5 HOW TO CONNECT A PC

NOTE!

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

communication errors.

 Example of 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 electric line and other high voltages inside

the inverter. However, it is not isolated from the protective earth (PE). Use an isolated laptop to hook the USB connector or desktop with connection to the same protective earth of the inverter.

Energization and Start-Up

5.7 OPERATION WITH A REDUCED NUMBER OF POWER UNITS

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

The general scheme of a drive with 5 UP11 is shown in Figure 3.31 on page 3-26. The reduced power mode works as a drive of up to 2 UP11.

Assume that in the drive of Figure 3.31 on page 3-26, composed of 5 UP11, UP11 number4 fails. 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 UP11 number4, according to Figure 5.5 on page 5-7.

4. Move the control connections on the ICUP board, as shown in Figure 5.6 on page 5-8. 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 Tabl e

3.31 on page 3-43.

6. Change DIP switch S1:4 to ON; thus, the control will be informed that the CFW-11M G2 RB or CFW-11W G2 RB 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 RB or CFW-11W G2 RB 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.

6 TROUBLESHOOTING AND MAINTENANCE

This chapter presents:

 The list of all faults and alarms.

 Most probable causes for each fault and alarm.

 The list of the most common problems and corrective actions.

 Instructions for periodical inspections of the product and preventive maintenance.

6.1 OPERATION OF THE FAULTS

When a fault (FXXX) is identified, what occurs is:

 Locking of the PWM pulses.

 Indication on the display of the fault description and code.

 The "STATUS" LED flashes red.

 The relay programmed for "NO FAULTS" is turned off.

 Saving of some data on the EEPROM of the control circuit:

- The fault or alarm code occurred (it moves the nine previous faults).

- The status of the hours enabled (P0043) and energized (P0042) counter.

 For the converter to return to normal operation right after the occurrence of a fault, it is necessary to reset it,

which can be done as follows:

- Switching off the power supply and switching it back on (power-on reset).

- Pressing the (manual reset) key.

- Via soft key "Reset".

- Automatically by means of the P0340 setting (auto-reset).

- Via digital input: DIx = 20 (P0263 to P0270).

When an alarm (AXXX) is identified, what occurs is: re:

 Indication on the display of the alarm description and code.

 The "STATUS" LED becomes yellow.

 The PWM pulses are not blocked and the converter remains in operation.

Display off HMI connections 1. Check the HMI connections outside the inverter

Wrong wiring 1. Check all the power and control connections. For example, the

DIx digital inputs programmed as general enable or without external fault must be connected to the 24 Vdc or DGND* (see

Figure 3.46 on page 3-39 and Figure 3.47 on page 3-39)

Wrong programming 1. Check if the parameters have correct values for the application Fault 1. Check if the converter is not disabled due to a fault condition

2. Check if there is a short circuit between terminals XC1:13 and 11 (short circuit in the 24 Vdc power supply)

ICUP supply voltage of 24 Vdc 1. Check the connections of the control 24 Vdc power supply

2. Check if the power supply limits are according to Table 3.28

Troubleshooting and Maintenance

6.4 INFORMATION NECESSARY FOR CONTACTING TECHNICAL SUPPORT

NOTE!

For technical support or queries, it is important to have the following data at hand:

 Converter model.  Serial number, manufacturing date and hardware revision indicated on the nameplate of the product

(see Chapter 2 GENERAL INFORMATION on page 2-1).

 Installed software version (see P0023).  Application and programming data.

6.5 PREVENTIVE MAINTENANCE

DANGER!

 Always disconnect the general power supply before touching any electrical component connected

to the converter.

 High voltages may still be present even after disconnecting the power supply.  Wait at least 10 minutes for the complete discharge of the power capacitors.  Always connect the equipment frame to the protective earth (PE) at the proper terminal.

ATTENTION!

Do not carry out any applied potential test on the converter!

If necessary, contact WEG.

When installed in proper environments and operating conditions, the converters require little maintenance. Tab le

6.3 on page 6-8 presents the main procedures and time intervals for preventive maintenance. Table 6.4 on page 6-9 contains the recommended inspections to be performed every 6 months after the start-up.

Table 6.3: Preventive maintenance

Maintenance Interval Instructions

Fill up the cooling ﬂuid with the corrosion

inhibitor CorteC VpCI-649 (UP11W G2)

Clean the cooling system and change the

coolant (UP11W G2)

(1) The converters 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 converter records in parameter P0045 the number of hours that the fan remained running. When the fan reaches 50,000 hours of operation, the HMI display will show alarm A177.
