3 PRODUCT CHARACTERISTICS

A brief theoretical explanation about the operation and a simpliﬁed electrical scheme of the power cells and their connections are presented below. The basic operation of the control system is presented at the end of this chapte r.

The MVW3000 is a frequency inverter designed to control medium voltage motors at the rated values of 2.3 kV to

13.8 kV and for a power range of 150 HP to 5400 HP. Based on a topology where the low voltage cells (< 1000 V) are connected in series to form each inverter phase, its assembly is modular, enabling different conﬁgurations if necessary to drive high power motors.

NOTE!

The characteristics contained in this manual were based on models of the standard MVW3000 intended for applications on 6.6 kV motors. Therefore, the MVW3000 used in the general illustrations will contain 18 low voltage power cells (six in series per phase). Notice that the MVW3000 can be engineered to meet the needs and technical speciﬁcations of our customers. Contact out technical team for more details.

3.1 INPUT TRANSFORMER

The MVW3000 inverter has an input transformer, because the cascade cell topology demands the feeding of each cell to be insulated from each other. This transformer is built so as to meet the different functions for the MVW3000, such as the necessary insulation for the power cells, cancellation of the harmonic current coming from the cell input rectiﬁers, and it also has an auxiliary winding responsible for the system pre-charge.

Product Characteristics

The transformer conﬁguration is made in star – extended delta, with phase-shifting angles j° between the secondary windings of one same phase. The main primary windings (star connection) and the auxiliary input windings (also star) do not present phase shifting between each other.

The transformer is designed according to the number of cells used on the inverter. 3x3xn windings (number of motor phases x number of cell input phases x number of cells per phase) form n isolated secondary windings that process 1/(3n) of the converter rated power, totalizing one secondary winding per cell.

Motor Voltage [kV] 2.3 3.3 4 .16 5.5 6-69 7. 2 8

Secondary Windings 3x2=6 3x3=9 3x4=12 3x 5 =15 3x 6 =18 3x7= 21 3x8=24

The transformer secondary windings have phase-shifting designed according to the number of cells and the speciﬁed harmonic level, and it may be engineered upon the customer’s request The phase-shifting help cancel the harmonic components coming from the non-controlled semiconductors devices. As each cell has a 6-pulse diode rectiﬁer at the input, and the secondary windings have a phase-shifting between each other, the transformer primary winding perceives multiples of six pulses in its windings.

The bigger the number of pulses, the smaller the phase-shifting angle between the secondary windings, and the smaller the Harmonic distortion rate observed by the transformer primary winding. Smaller phase-shifting angles imply more complex manufacture and parameter control of the transformer. Thus, a good complexityperformance ratio is sought.

For the 18-cell MVW3000, the 36-pulse transformer Figure 3.2 on page 3-3 is used, which offers good cost effectiveness with great performance regarding harmonic component cancellation and reduced cost, in comparison to transformers with more pulses.

Table 3.1 on page 3-2 contains the possible input transformer conﬁgurations for different numbers of cells

installed on the MVW3000 panel.

3.2 POWER CELLS

The power cells used on the arms of the MVW3000 are single-phase low voltage inverters (output voltage of 690 V

rms

), in a topology known as H bridge or full bridge. A basic diagram of the rms power cell circuit can be seen in Figure 3.4 on page 3-4. Each cell has the feeding of one own secondary winding (three-phase) of the main transformer, which ensures the converter medium voltage insulation.

The three-phase voltages of the input of the modules are then rectiﬁed by a Graetz bridge using non-controlled semiconductor devices (diodes), forming one own DC link (direct current) with the addition of the capacitors to the cell (represented by symbol C1). They can be electrolytic or plastic ﬁlm capacitors, depending on the model of the used cell.

Figure 3.4: Basic diagram of a power cell

IGBT (Insulated Bipolar Gate Transistor) controlled semiconductor devices are used to implant the inverter bridge in H; thus, each power cell has four IGBTs in the conﬁguration shown above. During operation, the voltage between FA and NE output terminals has three possible voltage levels. Considering that the DC link voltage of each cell is VDC and that only two IGBTs can be operating simultaneously (due to short circuit protection), when S1f and S2n are operating, the voltage between FA and NE will be + VDC, whereas if S1n and S2f start operating, the voltage between FA and NE will be –VDC. If S1n and S1f or S2n and S2f are turned on, the voltage, in both cases, will be equal the zero.

To protect the modules, two fuses F1 and F2 are connected to the input phases R and T, as shown in Figure 3.1

on page 3-1. In case a module presents some fault, the bypass system, when available, will be responsible for

circumventing the fault, removing it from the series and enabling the operation to continue.

When that occurs, control strategies will be applied so that the load remains operating. Further information can be found in Chapter 8 SPECIAL FUNCTIONS on page 8-1, in Section 8.3 CELL BYPASS on page 8-5.

Each power cell has one local control module. This module communicates with the main control module by means of an optical-ﬁber interface, necessary to obtain, in addition to the insulation degree required for the communication, noise immunity, greater robustness and reliability, characteristics necessary for the application. The local control makes acquisitions and monitors relevant magnitudes for the cell operation.

Some of the monitored magnitudes are the line voltages of the power cell, temperature of the diode modules and IGBTs, voltage of the DC link capacitors, voltage of the cell power supplies, among others.

The local control is also responsible for local activations, such as the switching of the IGBTs and the trigger of the bypass system. In case the cell presents readings out of the expected operation standards, for example, temperatures close to damaging the semiconductors, overvoltage on the DC link, or other faults predicted by the control, the bypass system may be activated for protection against a possible cell failure or for removing an already damaged cell from operation.

3.3 CONNECTION OF THE CELLS

To form a three-phase output, a number “n” of power cells that operate with 690 “V

rms

” of output are rms grouped in series per phase. The cell sets that represent phases U, V and W are connected in star conﬁguration, with a ﬂoating neutral in common with the phases, as indicated in Figure 3.5 on page 3-5.

Figure 3.5: Cell-to-phase connection diagram

Figure 3.6 on page 3-6 shows the transformer, input switchgear and secondary winding connected to each

cell. This association in series enables more voltage levels at the inverter output. Locally, each cell produces three voltage levels; however, at the converter three-phase output, it is possible to obtain 2n + 1 levels on the phase voltage and 4n+1 levels on the line voltage.

This effect occurs, because the voltage of each phase is instantaneously given by the addition of the voltages at terminals FA and NE of each cell pertaining to the analyzed phase. Figure 3.7 on page 3-7 shows the sum of the voltages of each cell to form the phase voltage in a 9-cell MVW3000 (3 per phase).

Therefore, increasing the number of cells per phase, in addition to enabling the drive of motors with higher voltages and powers, a better sinusoidal shaped wave is obtained. Thus, the converter provides a smaller THD (total harmonic distortion), reduction of noises and vibration on the motor, operating with high efﬁciency.

3.4 CONTROL

The MVW3000 has protections against overload, short circuit, current limit, under and overvoltage, overtemperature, ground fault and monitoring of the individual faults of each power cell. The control type can be selected by the user between: scalar control (constant V/f ratio) or vector control (sensorless or with feedback by speed sensor).

The MVW3000 inverter uses the PWM modulation technique (Pulse Width Modulation); from the direct voltage of each independent DC links, it synthesizes an alternate voltage with variable frequency and amplitude at the output terminals. The medium voltage level is obtained at the converter output terminals from the association of “n” low voltage cells in series. For further information on the central control, refer to Section 4.3 CONTROL RACK

The output currents of the three phases (motor currents) are measured using the Hall-effect CTs (current transformers). Those current signals are sent to the central control board. The measurement is done for indication on the HMI and for implanting the converter control and protection functions.

The pre-charge is done by means of an auxiliary winding of the input transformer, which is driven by the inverter auxiliary supply circuit via current limiter elements. In order to prevent high starting current levels on the inverter, activation of protection systems or even damages to its own components, the cell capacitor pre-charge must be done through and auxiliary winding of the input transformer. The auxiliary supply is also responsible for feeding the control circuit and fans for the panel cooling.

4 TECHNICAL DATA

This chapter contains technical information on the MVW3000, cabinet details, input transformer, power cell and control rack. It also provides information about the available output filters for the MVW3000.

4.1 MVW3000 PANEL

The MVW3000 is assembled as coupled panels forming four distinct compartments. In the ﬁrst column of the panel, to the left, are the input safety devices, such as fuses and the input circuit breaker/contactor (if installed). This part also shows the input transformer temperature on the temperature display. Below the safety devices, in a separate section, is the main medium voltage input transformer. In the central section, the inverter power cells are installed; each of the three columns shown in Figure 4.2 on page 4-2 represents each of the three inverter phases: U, V and W.

Figure 4.1: Closed panel of the 18-cell MVW3000 (Frame B6)

The handles of average tension that feed the cells of the invertor come from the secondary ones of the transforming one of entrance. The number of cables and conductor diameter varies according to the number and current of the cells installed on the MVW3000.

Each cell receives the input supply from and independent secondary winding insulated from the main transformer. In the right panel, in the upper compartment, is the control compartment, containing the main control, user interface, HMI, command and signalling, which are exclusively supplied by low voltage circuits.

The converter three-phase medium voltage output is located in the compartment below the control, and this compartment can also be used to install optional output ﬁlters.

The standard panels of the models equipped with drive system and input protection feature medium voltage fuses in order to protect the system against short circuit. The fuses must match the rated voltage of the input medium voltage circuit.

Table 4.1 on page 4-2 presents the fuse models recommended for the standard inverters where the input and

output voltage are the same; for applications with voltage values different between input and output, the fuse model will be informed upon request.

The standard panels supplied for the MVW3000 are suitable for connection to medium voltage circuits capable to supply a maximum symmetrical short circuit current of 40 kA.

4.1.1 Panel Constructive Aspects

The panel is made with steel sheets painted and processed (cutting, holes, folding, chemical treatment, painting and ﬁnishing) by WEG, ensuring the quality in all the levels of the manufacture process. The inverter parts that are not painted are zinc plated or have another suitable treatment in order to assure their resistance against corrosion.

The MVW3000 panel is supplied, in its standard structure, with degree of protection IP41 (openings smaller than 10 mm and protected against ingress of vertical drops). They can be supplied with distinct degrees of protection according to the customer’s needs.

The panel cooling is done by means of forced convection. The air enters through the opening on the panel front doors, goes through the transformer windings and also the power heatsinks located in each power cell. The hot air leaves through the top do painel, of the panel, where the exhaust fans are located, allowing maintenance without the need to open the inverter doors.

Page 31

MVW3000 | 4-3

Technical Data

Filter cleaning or replacement can be done by removing the external grid with no need to open the doors and to interrupt the inverter operation. The internal grid with openings smaller than 10 m prevents the access to the medium voltage compartment.

The MVW3000 complies with the international standards, such as harmonic limits, contained in IEEE-519 and G5/4-1 standards, and also electromagnetic emission (EMC), contained in IEC61800-3 standard.

The medium voltage compartments are mechanically and electrically interlocked so as to prevent the access to all the components that may present risk of electric shock with the system energized. Only after closing the transformer and inverter panel doors is it possible to open the grounding system and close the input switch disconnector.

In case of unlocking of the doors, the inverter will block the operation and turn off the input circuit breaker. The control panel is fed by an auxiliary power supply (220 V – 480 V), which may be blocked to prevent its activation.

 4 IGBTs with blocking voltage of 1.7 kV.

 1 heatsink for heat exchange.

 2 gate driver electronic boards.

 1 switched-mode power supply electronic board.

 1 local control electronic board with fiber optic interface.

 2 input protection fuses.

 2 temperature sensors.

The mechanical structure of each cell is basically formed by galvanized steel plates, and it is easy to install due to the connection clamp system and the insertion and extraction mechanism present in the the set.

As the connection and mounting of the cell to the MVW3000 do not require tools, a cell can be changed in few minutes, reducing the downtime. For further information about cell installation and replacement, refer to Chapter

6 INSTALLATION, CONNECTION AND ENERGIZATION on page 6-1.

Figure 4.6: Standard power cell boards and connections of the MVW3000 (frame B)

The local control and power supply electronic boards are in the upper part of the cell, above the laminated busbars, insulated and fastened to a metal base. The serial communication between the cell and the main control module occurs by means of the local control board via the ﬁber optic interface.

The modulation signals leave the local control and go to the gate driver boards by via multiway ﬂat cables. The power supply provides the voltages of: 5 V, 15 V, -15 V, 24 V that feed all the cell control part (local control, gate drivers and bypass system).

The celll connection to the link is carried out by means of clamps, located in the back part of the cell. There are ﬁve connections per cell, connecting it to the transformer three-phase secondary winding (terminals R, S and T) and to the serial circuit of the phase applied by terminals FA and NE (phase and neutral).

ATTENTION!

4.3 CONTROL RACK

For the control power supply, the auxiliary voltage (220 Vac - 480 Vac) must have available and connected to the speciﬁc terminal strip, located in the control panel. The provided transformer has taps for different voltages in the primary winding and supplies 220 Vac in the secondary winding to feed all the low voltage circuits and exhaust fans present in the product.

The MVW3000 control rack has four electronic boards, grouped in a mechanical assembly that enables better visualization and access to the analog, digital and ﬁber optic interfaces. For this assembly, MVC3, MVC4, FOI3 and PIC2 boards are represented.

The control rack is supplied with 24 Vdc by the PS24 power supply, whose input is at 220 V, single-phase or threephase. The control rack is composed of the interface and power supply board (PIC2), one control board (MVC3), the user’s function board (MVC4) and the ﬁber optic interface board (FOI3). The MVC3 board is responsible for the motor and inverter control, and the MVC4 for the user’s interface tasks. Both boards are supplied with isolated low voltages provided by the PIC2 board, where there are also opto-isolated digital inputs and relay outputs (220 Vac) for internal use of the MVW3000.

Optional Fieldbus communication and function expansion boards (EBA, EBB or EBC) can be connected to the MVC4 control board. The connections between the MVC3 board and the power stages are made with ﬁber-optic cables through the FOI interface boards.

ATTENTION!

4.4 OUTPUT FILTERS

Depending on the installation conditions, it may be necessary the addition of an output ﬁlter. For drives with cables between 200 and 500 m, it is recommended to use output ﬁlter on the motor phases. For drives with long cables, above 500 m, or for motors not able to operate with PWM modulation (retroﬁtting applications), it is recommended to use ﬁlter type 2 (contact WEG).

The available ﬁlter models follow the voltage and current informed in Table 2.3 on page 2-5 to Table 2.10 on

page 2-8.

Figure 5.1: General diagram of the inverter for synchronous motor

5.1 ABSOLUTE ENCODER WITH RSSI BOARD

In synchronous machine drive applications, it is necessary to use an absolute encoder so as to obtain the exact rotor position in relation to the stator, since the incremental encoder is not able to provide such information.

5.1.1 Absolute Encoder

The synchronous motor control requires the use of an absolute encoder, which must follow the following speciﬁcations:

Synchronous Serial Interface (SSI) communication protocol with RS-485 communication channel, with clock and 16 bit word size in the following format:

14 data bits 1 ZERO bit 1 even parity bit

Figure 5.2: Clock speciﬁcation and data transfer for the absolute encoder

Supply voltage of 15 V, with consumption lower than 300 mA.

Resolution of 14 bits per turn, which ensures a dynamic equivalent to the conventional incremental encoder;

When mounting the encoder next to the motor, it is recommended:

 Coupling the encoder directly to the motor shaft (using a flexible coupling, however without torsional flexibility).

 Both the shaft and the metallic frame of the encoder must be electrically isolated from the motor (minimum

distance of 3 mm).

Use good quality ﬂexible couplings that prevent mechanical oscillations or “backlash”.

NOTE!

The standard absolute encoder recommended for the MVW3000 is the Baumer MHAP 400 B5 XXXXSB14EZ D. The maximum encoder cable length is 120 m. Refer to the motor project to deﬁne the type of encoder mounting.

5.1.2 RSSI Board

The use of absolute encoder implies the need for an SSI data interface (Synchronous Serial Interface) between the encoder and the inverter. The RSSI board was developed for the encoder speciﬁcation previously described. This board has the following features:

Supply voltage of 24 V DC, with consumption of up to 700 mA.

RS485 communication channel for data transmission and clock according to SSI standard with absolute encoder; 2 ﬁber optic communication channels for use with up to two boards, MVC3 control and FOI3.

For electric connection, use shielded cables, keeping them at least 25 cm away from the other cables (power, control, etc.). Preferably inside a metal conduit.

5.2 FIELD EXCITATION SET (DC WITH BRUSHES)

The ﬁeld excitation of the synchronous motor can be done through an AC-DC converter that presents the possibility of being controlled by a control loop, and that has an input for current reference and presents an analogue output with the information of its output current (feedback for the MVW3000).

Speciﬁcations: Current reference input AC-DC: 0 V to 10 V (AC-DC 5 V = 1 PU, observe P0462); Feedback of the output current for the MVW3000: 0 V to 10 V (MVW3000 5 V = 1 PU, observe P0462 and P0744).

NOTE!

The MVC3 board has only voltage signals, in order to use current signals an external current transducer must be used.

Example of conﬁguration of the ﬁeld current reference and paremeter setting of the inverter is presented in

ATTENTION!

During lifting, connect chains or cables to all available hoisting points on the panel.

6.1.4 Moving

When cranes or pulleys are used, make sure that the movements are slow and smooth, so that the panel and the arms do not suffer excessive swings and vibration.

When using movable hydraulic jacks, forklifts, rollers or other means, distribute the support points from one extreme through the other, avoiding pressure on fragile areas. Make sure that all the panel doors be closed and locked, and that the door handles be in protected position.

The transformer panel door must be handled with forklift only. For information about the transformer mass, see Table 6.1 on page 6-2.

6.1.5 Unpacking

Use proper tools to unpack the MVW3000 panel and its arms. During this process, make sure that all the items listed in the documentation that comes with the product are present and in perfect conditions. Contact your local WEG representative in case of any irregularity.

Removes the package of the cells carefully, because they have fragile components (electronic boards, ﬁber optic connectors, busbars, wiring, etc.). Avoid touching these components! The arms must always be handled through their external metallic frame.

While opening the package, check if there are damages to the product. Do not to install the cells in case you suspect any damage.

Remove all packing material (plastic, wood, polystyrene foam, metal, nails, bolts, nuts, etc.) that might have remained inside the inverter panel or in the arms.

6.3 ENERGIZATION, START-UP AND SAFE DE-ENERGIZATION

This section provides the following information:

 How to check and prepare the inverter before powering-up.

 How to power-up and verify the energization success.

 How to operate the inverter when installed according to the standard project (refer to the Section 6.2 ELECTRICAL

INSTALLATION on page 6-10 and the attached electric project).

 How to de-energize the inverter safely.

6.3.1 Pre-power Checks

The inverter must have already been installed according to the Chapter 6 INSTALLATION, CONNECTION AND

ENERGIZATION on page 6-1. Even when the inverter electric project is different from the suggested one in the

attachment, the following recommendations are applicable.

DANGER!

 Always disconnect all the power supplies before making any connections.  Although the inverter commands the opening of the input cubicle, there is no guarantee of its

opening and neither that no voltages are present.

DANGER!

 Débranchez toujours toutes les alimentations avant d’effectuer des branchements.  Bien que l'onduleur commande l'ouverture de l'armoire d'entrée, il n'y a aucune garantie de son

ouverture et ni qu'aucune tensions sont présentes.

In order to open the medium voltage cabinets, follow all the safe de-energization procedures.

Page 55

MVW3000 | 6-15

Installation, Connection and Energization

1. Check if all the power, grounding and control connections are correct and tightened.

2. Clean the inverter internally, remove all packing material and installation residues from within the MVW3000 cabinets.

3. Check all motor connections and verify whether its voltage, current and frequency match the inverter speciﬁcations.

4. If it is possible, decouple the motor mechanically from the load. If the motor cannot be decoupled, then make sure that rotation in any speed direction (Forward or reverse) is not hazardous to people or to the machine.

5. Close and lock the panel doors.

6.3.2 Initial Power-up (Parameter Settings)

After the preparation for power-up, the inverter can be energized, according to the following steps:

Make sure:

1. The auxiliary power supply voltage and the medium voltage supply line voltage are available in the input switchgear. Check that the low voltage auxiliary power supply voltage that feeds the control panel is within the allowed range (rated voltage + 10 %/-15 %).

2. The control panel circuit breakers are installed according to the electrical project. Then closes the door of the control panel.

3. The emergency button is not activated.

4. The control panel was energized, the switch-disconnector of the control panel auxiliary power supply is closed, and check the initialization of the main control through the HMI.

5. The ﬁrst power-up was successful, the initialization process was completed and the status of the HMI is indicating inverter ready.

6.3.3 Start-up

This section describes the inverter start-up with keypad operation. The considered control mode is V/F 60 Hz.

DANGER!

 High voltages may be present even after the power supply disconnection.  The following sequence is valid for the standard MVW3000 inverter. The inverter should have

already been installed and programmed, according to Chapter 6 INSTALLATION, CONNECTION

AND ENERGIZATION on page 6-1.

DANGER!

 Des tensions élevées peuvent être présentes même après déconnexions de l’alimentation.  La séquence suivante est valable pour l’onduleur du MVW3000 standard. L’onduleur doit déjà

avoir été installé et programmé, comme décrit respectivement dans le Chapter 6 INSTALLATION,

CONNECTION AND ENERGIZATION on page 6-1.

6.3.3.1 Start-up with HMI Operation and V/F 60 Hz Control Mode

1. Apply power to the panel close the disconnector switch at the control column power supply input.

2. Once the control panel is energized, the main control board will go into the initialization process, and the HMI will show the message “booting”:

- After the control has ﬁnished its initialization (approximately 10 seconds), the message “Inverter in Undervoltage” is presented on the HMI.

Page 56

6-16 | MVW3000

Installation, Connection and Energization

At this moment the inverter is in undervoltage state (DC link is discharged) and the “ready to start” pilot light (H1) at the control column door is on, indicating that it is already possible to initiate the inverter pre-charge.

3. Initiate the pre-charge / power section energization. The MVW3000 inverter pre-charge command must be given manually:

 With the ready to energize indicating light turned on, press the ON button.

 Wait until the pre-charge is finished (approximately 15 seconds). During the pre-charge the pilot light must

remain on.

 Once the pre-charge is successfully completed, the pre-charge indicating light (PRECHARGE) will turn off and

the Energized light will turn on, indicating the input switchgear was successfully closed.

 The “inverter ready” message is displayed on the HMI.

NOTE!

The pre-charge procedure must not be repeated before 15 minutes. Doing so may damage the precharge system due to overload.

ATTENTION!

If during the pre-charge any problem occurs, the inverter indicates an error related to it. The possible errors are: F0092 – Pre-charge circuit not ready. F0014 – Fault in the closing of the input switchgear. F0017 – Input switchgear not ready. F0020 – Time exceeded in the pre-charge process. See the description of those faults/alarms in the programming manual available for download on:

www.weg.net.

NOTE!

The last speed reference value, set via the and keys, is saved in the memory (P0120 = 1). If you want to change this value before enabling the inverter, change it through the parameter P0121

- (Keypad Speed Reference), which stores the keypad speed references.

NOTES:

1. If the motor speed direction is inverted, switch off the inverter following the safe de-energization instructions and swap two of the motor cables. The HMI must indicate the same direction seen looking against the motor shaft end.

2. It the current is too high during the acceleration, especially at low speeds, it is necessary to reduce the acceleration ramp time (P0100 or P0102) or change P0136 - Torque boost setting.

Gradually increase and decrease the P0136 content until reaching an operation with approximately constant current throughout the entire speed range. In the case above, see the description of the parameters in the programming manual available for download on: www.weg.net.

3. In case some DC link overvoltage fault occurs during the deceleration, it will be necessary to increase the deceleration time through P0101/P0103 and check P0151.

Page 57

MVW3000 | 6-17

Installation, Connection and Energization

ATTENTION!

If the inverter receives a general enabling or a start command before the pre-charge has been ﬁnished (inverter still in undervoltage state), the command will be ignored and a warning message “inverter undervoltage” will be displayed on the HMI.

6.3.4 Safe De-energization Instructions

DANGER!

 Although the inverter commands the opening of the input cubicle, there is no guarantee of its opening

and neither that no voltages are present, because the capacitors remain charged for a long time and they can also be charged through the auxiliary supply (pre-charge).

 In order to open the medium voltage cabinets, follow all the safe de-energization procedures

described next.

DANGER!

 Bien que l'onduleur commande l'ouverture de l'armoire d'entrée, il n'y a aucune garantie de son

ouverture et ni qu'aucune tensions sont présentes, parce que les condensateurs rester chargé pendant un long moment et ils peuvent également être facturés par le biais de l'alimentation auxiliaire (pré-charge).

 Pour ouvrir les armoires moyenne tension moyenne, suivez toutes les procédures de mise hors

tension de sécurité décrites ci-dessous.

1. Decelerate the motor to a complete stop.

2. See the DC link voltage of the installed power cells at parameters P1000 to P1031 on the HMI.

3. Press the “POWER OFF” pushbutton. The input transformer cubicle is switched off at this moment, and the “INPUT ON” pilot light going off indicates it.

ATTENTION!

If the input transformer cubicle does not open with the “POWER OFF” command, then open it manually.

4. Monitor the DC link voltage decrease through the respective parameters on the HMI. Even with the indication of zero volt, wait for ten minutes so as to ensure the full discharge of the DC link capacitors.

5. Press the emergency pushbutton located on the control column door and remove its key.

6. At the input transformer circuit breaker cubicle, extract the circuit breaker from its operation position and close the transformer primary winding grounding switch. Lock the cubicle with the key and/or put a warning sign “System in maintenance”.

7. Switch off the Q2 circuit breaker in the control column and lock it in the open position with a padlock and/or put a warning sign “System in maintenance”.

8. Switch off the Q1 circuit breaker in the control column. Remove the auxiliary power supply.

It is only after the sequence of procedures here that medium voltage compartment doors can be opened.

DANGER!

Even after the DC link voltage parameters indicate 0 V on the HMI, 250 V may still be present on the DC link of the power cells. Wait for ten minutes, and the cabinet doors may be opened.

DANGER!

Même lorsque les paramètres de tension du câble CC indiquent 0 V sur l’IHM, une tension de 250 V pourra malgré tout être présente sur le bus CC des batteries. Merci d’attendre dix minutes et les portes de l’armoire devraient s’ouvrir.

Related parameters: P0221, P0222, P0234 to P0240.

During the signal and control wiring installation, pay attention to:

1. Cable gauge 0.5 mm² to 1.5 mm².

2. Maximum torque: 0.50 N.m (4.50 lbf.in).

3. XC1A, XC1B and XC1C wiring must be made with shielded cables and be separated from other cables (power, 110/220 V command, etc.). If crossing of these cables is unavoidable, install them perpendicularly, keeping a minimum separation distance of 5 cm (2 in) at the crossing point.

Connect the shield as shown below:

The shield connection screws are located on the MVC4 board and on its mounting plate.

Insulate with tape

Connect to the ground

Do not ground

Inverter side

Figure 7.5: Shield connection

4. It is necessary to use galvanic isolators at the XC1B terminal strip signals for wiring distances longer than 50 m (150 f t).

5. Relays, contactors, solenoids or electromagnetic braking coils installed near inverters can generate interference in the control circuit. In order to eliminate this interference, connect RC suppressors in parallel with the coils of AC relays. Connect a free-wheeling diode in case of DC relays/coils.

6. When an external keypad (HMI) is used (for further information, refer to the programming manual available for download on: www.weg.net), separate the cable that connects the keypad to the inverter from other cables of the installation, keeping a minimum distance of 10 cm (4 in) between them.

7.2 FUNCTION EXPANSION BOARDS

The function expansion boards increase the MVC4 control board functions. There are 3 expansion boards available and their selection depends on the application and the desired functions. The three boards cannot be used simultaneously. The difference between the EBA and EBB boards is in the analog inputs/outputs. The EBC1 board serves for the encoder connection; however, it does not have its own power supply as do the EBA/EBB boards. Next, the detailed description of those boards is presented.

7.2.1 EBA (I/O Expansion Board A)

7.3 INCREMENTAL ENCODER

Applications that require more speed or positioning accuracy, a speed feedback of the motor shaft by means of incremental encoder is required. The connection to the inverter is made through the XC9 connector (DB9) on the EBA function expansion board, or XC9 on EBB, or XC10 on EBC.

7.3.1 EBA/EBB Boards

When the EBA or EBB board is used, the selected encoder should have the following characteristics:

Power supply voltage: 12 Vdc, less than 200 mA current consumption.

2 quadrature channels (90º) + zero pulse with complementary outputs (differential):

 Signals A, A, B, B, Z and Z.

 "Linedriver" or "Push-Pull" output circuit type (12 V level).

 Electronic circuit isolated from the encoder frame.

 Recommended number of pulses per revolution: 1024 ppr.

Follow the recommendations bellow when mounting the encoder on the motor:

 Couple the encoder directly to the motor shaft (use a flexible coupling without torsional flexibility).

 Both the shaft and the metallic frame of the encoder must be electrically isolated from the motor (3 mm (0.119

in) minimum distance).

 Use high quality flexible couplings to prevent mechanical oscillation or backlash.

The electrical connections must be made with shielded cable, maintaining a minimum distance of about 25 cm (10 in) from other wires (power, control cables, etc.). If possible, install the encoder cable in a metallic conduit.

Page 73

MVW3000 | 7-15

Optional Accessories and Boards

During the commissioning, it is necessary to program the control type, P0202 = 4 (Vector with Encoder), in order to operate with speed feedback via incremental encoder.

For further details on vector control, see the programming manual available for download on: www.weg.net.

The function expansion boards EBA and EBB have an encoder signal repeater, isolated and externally powered.

(1) Power supply voltage 12 Vdc / 220 mA for encoder. (2) Referenced to ground via 1 μF in parallel with 1 kΩ. (3) Connector pinout valid for HS35B Dynapar encoder. For other encoder models, verify the correct connection in order to meet

the required sequence.

ENCODER MOUNTING:

Follow the recommendations bellow when mounting the encoder on the motor:

 Couple the encoder directly to the motor shaft (use a flexible coupling without torsional flexibility).

 Both the shaft and the metallic frame of the encoder must be electrically isolated from the motor (3 mm (0.119

in) minimum distance.

 Use high quality flexible couplings to prevent mechanical oscillation or backlash.

During the commissioning, it is necessary to program the control type, P0202 = 4 (Vector with Encoder), in order to operate with speed feedback via incremental encoder.

For further details on vector control, see the programming manual available for download on: www.weg.

7.4 SHORT UPS MODULE

The Short UPS module is an accessory that provides autonomy of approximately 500 ms in case of failure of the MVW3000 inverter auxiliary power supply. After the occurrence of the auxiliary power supply failure, the inverter remains operational, without faults, during 500 ms.

The module is based on a low voltage frequency inverter, CFW10 and an external capacitor bank, which ensure the energy supply to the power supplies during the speciﬁed period. A ﬁlter is added to the inverter output, necessary because of the characteristic of the fed loads.

The Short UPS feeds the following loads:

 PS1S power supply: responsible for feeding the gate drivers.

 PS24 power supply: responsible for feeding the control.

 General command: input circuit breaker supply and its undervoltage release.

7.4.1 CFW10 Inverter Parameterization

 For the correct operation of the Short UPS module, the CFW10 inverter must be parameterized as shown below:

 P100 = 1.0 (Acceleration time).

 P101 = 0.5 (Deceleration time).

 P121 = 57.4 (Output frequency).

 P206 = 3 (Auto-reset time).

 P222 = 0 (Remote speed reference).

 P263 = 0 (DI1 Digital input).

 P264 = 0 (DI2 Digital input).

 P265 = 4 (DI3 Digital input).

 P266 = 6 (DI4 Digital input).

 P297 = 10 kHz (Switching frequency).

8 SPECIAL FUNCTIONS

8.1 LOAD SHARE FUNCTION “MASTER/SLAVE”

Conveyors belts and overhead cranes are classic examples of applications where the torque or position control is used to maintain the conveyor belt voltage within the limits during the operation, start and stop procedures or even in the transportation of materials in a rising of falling slope.

For motors connected to the same load, it is necessary to ensure a reliable load sharing. Such characteristic is best achieved with the use of multiple inverters operating in speed reference mode (Master) and torque limitation mode (Slave (s)).

Implementation Modes

Three modes to implement the load sharing function will be presented. For the ﬁrst two modes, it is mandatory that the inverters involved in the process be set to vector operating mode. For most applications, the vector operating mode with speed or position sensor is recommended.

In order to implement the load sharing, the inverter assigned as master controls the load speed using all the other inverters of the process as actuators.

In the vector mode, there are two ways to implement the load sharing function: in the ﬁrst one, the master inverter sends the slaves the torque reference signal; in the second one, it sends the torque reference limitation signal. The mode to be used must be analyzed for each application.

For operation in scalar mode with load sharing, all inverters must receive the same speed reference signal. This type of load sharing is called “droop” or negative slip.

The three implementation methods and the main parameters used in each method are shown below.

Torque Reference - Operation in Vector Mode

One of the possible ways to implement the load sharing function is by parameterizing the salve inverter(s) to follow an external torque reference, which will be sent by the master inverter.

In order to do so, the inverters must be parameterized as follows:

Master:

Parameterize one of the analog outputs of the MVC3 control board to send the torque reference to the slave inverter(s). In the example below, the analog output AO1 is parameterized.

P0652 (Analog Output 1 Function) = 188 (Inverter torque reference).

Page 80

8-2 | MVW3000

Special Functions

Slave(s):

On the slave inverter(s), it is necessary to parameterize an analog input of MVC3 board to receive the torque reference sent by the master inverter.

P0740 (Analog Input 1 Function) = 1 (Torque reference).

NOTE!

Observe the polarity of the analog ones at the moment of the connection between the inverters.

Limitation of the Torque Current - Operation in Vector Mode

As in the previous mode, the master inverter operates in speed control mode, while the slave inverter operates in torque current regulation mode. Besides the limit value of the torque current, the slave inverter(s) receives the speed reference signal; therefore, in a potential situation of sudden load reduction, the speed reference is saturated, thereby avoiding a possible sudden acceleration of the motor.

The speed reference signal sent to the slave inverter(s) must be set to a value slightly above the master inverter reference. It is recommended to apply an offset to the analog inputs of the slave(s) greater than 5 % added to the reference sent by the master inverter; the ideal value may vary according to the application.

NOTE!

As the operation with negative torque reference is impossible, this method cannot be used for regenerative inverters or with dynamic braking.

Therefore, the inverters must be parameterized as follows:

Master:

Parameterize one of the analog outputs of the MVC3 board to send the torque current limit to the slave inverter(s). The example below shows the parameterization of analog output AO1 of the MVC4 board to send the speed reference.

P0652 (Analog Output 1 Function - MVC3) = 188 (Inverter torque reference).

P0251 (Analog Output 1 Function - MVC4) = 0 (Speed reference).

Slave:

The slave inverter(s) requires the parameterization of an analog input of the MVC3 board to receive the torque current limit sent by the master inverter. For the speed reference, use the analog input AI1 of the MVC4 board, whose standard function is the speed reference signal.

Page 81

MVW3000 | 8-3

Special Functions

MVW3000 | 8-3

P0740 (Analog Input 1 Function - MVC3) = 2 (Torque Current Limit).

P0221/P0222 (Speed Reference Selection Local/Remote Situation) = 1 (AI1 - MVC4).

P0236 (Input AI1 Offset) = 5.0 %.

P0133 (Minimum Speed Reference) = set according to the application.

P0134 (Maximum Speed Reference) = set according to the application; it must be 5 % above the maximum limit of the master inverter.

Negative Slip – Operation in Scalar Mode

This method to implement the load sharing function is limited to applications of induction motor drive. It is based on the decrease of the frequency according to the increase of load on the motor; thus there is a natural distribution of the loads.

Regardless of the chosen speed reference source, it must be sent to all inverters. Due to the low accuracy of analog inputs, its use as speed reference source is not recommended.

This method to implement the load sharing must not be used for applications that require dynamic performance, which can only be used when the inverters drive motors with the same characteristic slip.

Therefore, the inverters must be parameterized as follows:

P0138 (Rated slip) = the motor slip is recommended (negative signal).

P0139 (Output current ﬁlter) = it is recommended to start with the standard value and gradually increment it if the system presents instability.

Besides the presented parameterization, the implementation of the load sharing function requires that all inverters involved in the process be enabled simultaneously; thus, the “General Enable” and “Run/Stop” signals must be sent to all inverters at the same time. There are several ways to meet this requirement and the most appropriate way will depend on each application.

The description given of the ways to implement the load sharing function intends neither to approach all possibilities of implementation, nor to detail all the aspects involved. The deﬁnition of the best implementation mode for a certain application, as well as the optimal adjustment of each mode must be deﬁned by WEG engineering and application teams.

8.2 SYNCHRONOUS TRANSFER FUNCTION

For applications where speed variation is not required during operation, the synchronous transfer function enables the motor to be accelerated through the inverter up to the rated operating frequency, and then the transfer to the supply line occurs. Thus, it is possible to eliminate the effects of the starting current related to a direct on-line start, and the inverter is sized only for the motor starting condition.

Figure 8.4: General scheme of synchronous transfer

Basic Settings

The synchronous transfer process involves accelerating the motor up to the rated speed, synchronizing the voltage imposed to the motor with the line voltage, and making the transfer to the line. For the transfer to occur properly and with minimal impact on the motor and on the inverter, a series of parameters must be carefully adjusted so as to ensure the phase synchronization, the minimum difference of the RMS value between the inverter and the line voltages and the timely occurrence of each step of the process.

Even with the correct setting of parameters related to the synchronous transfer process, it is necessary to use a reactor between the inverter and the motor in order to absorb differences between the inverter and the line voltage, thus protecting the inverter during the closing of the line contactor.

Therefore, after making all the start-up procedure for inverter with operation in normal mode, it is necessary to:

 Configure the motor voltage (P0400) equal to the line voltage to which the motor will be transferred. In the

operation with synchronous bypass, the inverter uses this value to calculate the RMS voltage that will be imposed to the motor when operating at rated frequency.

E.g.: motor nameplate voltage of 4000 V and line of 4160 V. Conﬁgure P0400 = 4160 V.

 Configure the inverter in synchronous transfer mode.

 Choose one of the DIs available on the MVC4 board (DI3 to DI10) and configure it to start the synchronous

transfer (P0265 to P0272 = 23 or 25).

 Configure one DO (RL1 to RL5) to indicate that the synchronism with the line is “OK” (P0277 to P0282 = 34).

Parameterization Used for Most Applications

In addition to the aforementioned basic settings, other parameters must be set for the correct operation of the function. Below is a quick description of each parameter, as well as the setting used in most applications.

 P0629 = 2 s Minimum time for which the inverter will have to keep the phase error between the input and

output voltage lower than the setting in P632 so as to signal synchronism OK.

 P0630 = 60 s Synchronism with the network time out. Time counted from the drive of the MVC4 DI, which

starts searching until the signaling of synchronism OK. If this time is exceeded, A0008 will be indicated.

 P0631 = adjusted in the application Delay of DI13 of the PIC2 board used to disable the inverter after the

bypass. This time is used to compensate the delay of the bypass circuit, preventing the motor from remaining for a period without voltage.

 P0632 = 1966 Phase error between the network and inverter voltage used in conjunction with P0629 to indicate

synchronism OK. (P0632/65536)*360º = value in degrees.

8.3 CELL BYPASS

The MVW3000 has the cell bypass system as optional function. For this function to be available, the MVW3000 power cells must have the bypass system integrated. The bypass system goes into operation if some fault is detected inside a cell. If a fault occurs, the main control requests the local control to activate the bypass system, the main control inhibits the IGBT command pulses of the cell and starts ignoring the fault signals of this cell, informing that the cell number “X” of phase “Y” went into bypass mode.

It is important to point out that during this process, the inverter continues operating normally with a small reduction in the output voltage. Control techniques will be used for the application to continue operating normally. For applications that cannot operate with reduced voltage, it is recommended to use an MVW3000 with voltage above the motor rated voltage so as to withstand the load at full voltage even with a higher number of cells out of operation simultaneously.

Figure 8.6: Power cell with bypass system active

Figure 8.6 on page 8-6 exempliﬁes the power cell operation with the bypass system active. The current of the

respective phase passes through the bypass system, and the cell no longer processes any energy. Therefore, the inverter current capacity, when in bypass mode, is not reduced. That occurs due to the connection in series of the power cells.

8.4 ANGLE ADJUSTMENT

During the operation of the MVW3000 in bypass mode, the inverter current capacity is preserved, because of the connection is series of the power cells. Differently, the maximum voltage available at the motor terminals will smaller, due to the connection in series. Such effect is not desired, since the motor torque is directly related to the voltage and current applied to its terminals. In addition to the smaller voltage available for the load, the inverter output also becomes unbalanced, jeopardizing the motor operation. Those problems can be circumvented by using the technique of angle adjustment between the converter phases.

This technique consists in modifying the phase voltage angles so as to keep the balance between the line voltages. Thus it is possible to maximize the line voltages and have a smaller impact of the cell bypass on the application voltage. In order to exempliﬁes how the technique works, it is possible to represent an 18-cell MVW3000 (6 per phase) for 18 power supplies (6 in series per phase, connected in Y to the neutral point). Under normal operation of the inverter, with all the cells operating, the phase voltages are shifted 120° between each other, and the line voltages have the same amplitude, as shown in Figure 8.7 on page 8-7 (a).

In bypass, without the angle adjustment technique, the line voltages are unbalanced, since the shift between the phases is still 120°. This process can be seen in Figure 8.7 on page 8-7 (b). In practice, this case is not compatible with the operation of the application; therefore, as soon as the cell bypass occurs, the inverter applies the angle adjustment method to balance the line voltages.

For such situation, where 3 cells of phase W are out of operation and without the angle adjustment, Vvw and Vwu voltages would fall down to 76 % (0.76 p.u.) of the inverter rated operating voltage, even having 15 cells in operation (approximately 83.3 % of the cells). As the inverter neutral point is not connected to the motor, its relative position can be easily changed by the angles of the phase voltages. Thus, even with the phase voltages unbalanced, it is possible to obtain balanced line voltages with the best use of the available voltage.

With the angle adjustment, presented in Figure 8.7 on page 8-7 (c), it is possible to observe that the line voltages remain balanced. The phase voltages have different shifts now. The voltage available at the motor terminals is now 80% (0.80 p.u.) of the inverter rated voltage.

Line Termination The initial and the end points of the network must present the characteristic impedance, in order to prevent reﬂections. The DB9 cable male connector has the suitable termination resistor. When the inverter is the ﬁrst or the last of the network, the termination resistor switch must be set to “ON”. Otherwise, leave the switch in the “OFF”position. The terminating switch of the Proﬁbus DP board must be set to 1 (OFF).

Baudrate The baud rate of a Proﬁbus DP network is deﬁned during the master conﬁguration and only one rate is allowed in the same network. The Proﬁbus DP board has automatic baud rate detection and the user does not need to conﬁgure it on the board. The supported baud rates are 9.6 kbits/s, 19.2 kbits/s, 45.45 kbits/s, 93.75 kbits/s,

187.5 kbits/s, 500 kbits/s, 1.5 Mbits/s, 3 Mbits/s, 6 Mbits/s and 12 Mbits/s.

9.1.3 DeviceNet

The DeviceNet communication is used for industrial automation, mainly for the control of valves, sensors, input/ output units and automation equipment. The DeviceNet communication link is based on a communication protocol “broadcast oriented”, the Controller Area Network (CAN). The physical medium of the DeviceNet network consists of a shielded cable comprising a twisted pair and two wires for the external power supply. The baud rate can be set to 125 kbits/s, 250 kbits/s or 500 kbits/s. Figure 9.7 on page 9-5 shows a general view of a DeviceNet network.

9.1.6.1 Variables Read From the Inverter

1. Inverter logical status.

2. Motor speed, for the option P0309 = 1 or 4 (2I/O) - read 1 and 2.

3. Digital input status (P0012).

4. Parameter contents, for the option P0309 = 2 or 5 (4I/O) - read 1, 2, 3 and 4.

5. Parameter contents, for the option (P0009).

6. Motor current (P0003), for the option P3009 = 3 or 6 (6I/O) - read 1, 2, 3, 4, 5 and 6.

1. Status word (EL): The status word is composed by a total of 16 bits, 8 high order bits and 8 low order bits. It has the following construction:

High-order bits - they indicate the status of the associated function. EL.15 - Active error: 0 = No, 1 = Yes. EL.14 - PID Regulator: 0 = Manual, 1 = Automatic. EL.13 - Undervoltage of the electronics power supplies: 0 = Without, 1 = With. EL.12 - Local/Remote command: 0 = Local, 1 = Remote. EL.11 - JOG command: 0 = Inactive, 1 = Active.

(*)

- Start/Stop: 0 = Stop, 1 = Start.

(*) O EL.08 = 1, means the inverter received the Run/Stop command via networks. This EL is not intended to signal that the motor is effectively spinning.

Low-order bits -they indicate the error code number, i.e., 03, 07 or 87 (57h).

For further information on the faults and alarms, refer to the programming manual available for download on: www.weg.net.

2. Motor speed: This variable is shown by using 13-bit resolution plus signal. Thus, the rated value will be equal to 8191 (1FFFh) (Forward) or -8191 (E001h) (Reverse) when the motor is running at synchronous speed (or base speed, for instance 1800 rpm for a IV-pole motor, 60 Hz).

3. Digital input status: It presents the parameter P0012 contents, where 1 indicates an active input and 0 indicates an inactive input.

For further information on parameters, refer to the programming manual available for download on: www.weg.net.

The digital inputs of this WORD are distributed as follows: Bit.7 - DI1 status. Bit.2 - DI6 status. Bit.6 - DI2 status. Bit.1 - DI7 status. Bit.5 - DI3 status. Bit.0 - DI8 status. Bit.4 - DI4 status. Bit.8 - DI9 status. Bit.3 - DI5 status. Bit.9 - DI10 status.

4. Parameter contents: This position allows reading the contents of inverter parameters, which are selected at the position 4 - Number of the parameters to be read - of the variables written in the inverter. The read values have the same order of magnitude of those described in the product manual or showed on the HMI. The values are read without the decimal point, if that is the case. Examples:

1. HMI displays 12.3, the Fieldbus reading will be 123.

2. HMI displays 0.246, the Fieldbus reading will be 246.

There are some parameters whose representation on the LED display can suppress the decimal position when the values are higher than 99.9. These parameters are P0100, P0101, P0102, P0103, P0156, P0157, P0158, P0169 (for P0202 < 3), P0290 and P0401. Example: Indication on the LED display: 130. Indication on the LCD : 130.0, Fieldbus reading is: 1300. The reading of parameter P0006 via Fieldbus has the meaning presented in the detailed description of the parameters, refer to the programming manual available for download on: www.weg.net.

5. Torque current: This position indicates P009 parameter contents, without the decimal point. A low pass ﬁlter with a time constant of 0.5 s ﬁlters this variable.

6. Motor current: This position indicates P003 parameter contents, without the decimal point. A low pass ﬁlter with a time constant of 0.3 s ﬁlters this variable.

9.1.6.2 Variables Written in Inverter

The variables are written in the following order:

1. Control word.

2. Motor speed reference, for the option P309 = 1 or 4 (2I/O) - it writes in 1 and 2.

3. Status of the digital outputs.

4. Number of the parameters to be read, for the option P0309 = 2 or 5 (4I/O) - it writes in 1, 2, 3 and 4.

5. Number of the parameter to be changed.

6. Content of the parameter to be changed, selected in the previous position, for the option P0309 = 3 or 6 (6I/O)

- it writes in 1, 2, 3, 4, 5 and 6.

1. Control word (C.L.): The control word is composed by a total of 16 bits, 8 high order bits and 8 low order bits. It has the following construction:

High-order bits - they select the functions to be controlled, when the correspondent bits are set to 1. CL.15 - Inverter fault reset. CL.14 - Without function. CL.13 - To save the changes of parameters P0169/P0170 in the EEPROM. CL.12 - Local/Remote command. CL.11 - Jog command. CL.10 - Forward/Reverse. CL.09 - General Enabling. CL.08 - Start/Stop.

Low-order bits - they determine the activation of the functions selected in the high-order bits, CL.7 - Inverter fault reset: every time it changes from 0 to 1 it causes an inverter reset, except for the errors (except A0124, A0125, A0126 and A0127); CL.6 - No function. CL.5 - To save P169/P170 in the EEPROM: 0 = to save, 1 = not to save. CL.4 - Local/Remote command: 0 = Local, 1 = Remote. CL.3 - Jog command: 0 = Inactive, 1 = Active. CL.2 - Forward/Reverse: 0 = Reverse, 1 = Forward. CL.1 - General enabling: 0 = Disabled, 1 = Enabled. CL.0 - Start/Stop: 0 = Stop, 1 = Start.

Page 98

9-10 | MVW3000

Communication Networks

9-10 | MVW3000

NOTE!

 The inverter will only execute the command defined in the low-order bit if the correspondent high-

order bit is set to 1 (one). If the high-order bit is set to 0 (zero), the inverter will disregard the value of the correspondent low-order bit.

 CL.13: The function of saving parameter content changes in the EEPROM occurs normally when the

HMI is used. The EEPROM allows a limited number of writings (100.000). In applications in which the speed regulator remains saturated and torque control is required, this control can be achieved by adjusting the torque limits P169/P170 (valid for P202 > 2). Therefore, if the network master keeps writing continuously in P169/P170, then the correspondent bits must be programmed in order to avoid that every change be saved in the EEPROM by setting: CL.13 = 1 and CL.5 = 1.

In order to enable the functions of the Control Word, it is necessary to set the inverter respective parameters with the option “Fieldbus”.

a) Local/Remote Selection Source - P0220. b) Speed Reference - P0221 and/or P0222. c) Forward/Reverse Selection - P0223 and/or P0226. d) General Enabling, Start/Stop Selection - P0224 and/or P0227. e) JOG Selection - P0225 and/or P0228.

2. Motor speed reference: This variable is presented using a 13 bit resolution. Therefore, the speed reference value for the motor synchronous speed will be equal to 8191 (1FFFh). This value must be used only as the base speed for the calculation of the desired speed (speed reference).

Examples:

1. 4-pole, 60 Hz motor, synchronous speed = 1800 rpm and speed reference = 650 rpm.

1800 rpm - 8191 650 rpm - X X = 2958 = 0B8Eh

This value (0B8Eh) must be written in the second word, which represents the motor speed reference (according to the beginning of this item).

2. 6-pole, 60 Hz motor, synchronous speed = 1200 rpm and speed reference = 1000 rpm. 1200 rpm - 8191 1000 rpm - X X = 4096 = 1AAAh

This value (1AAAh) must be written in the second word, which represents the motor speed reference (according to the beginning of this item).

NOTE!

Values above 8191 (1FFFh) are allowed when speed references above the motor synchronous speed are required, as long as the maximum programmed speed reference is respected.

3. Status of the digital outputs: It allows controlling the status of the digital outputs that have been programmed for Fieldbus at the parameters P0275 to P0282. 16 bits, with the following construction, form the word that deﬁnes the status of the digital outputs:

High-order bits: they deﬁne the outputs to be controlled, when set in 1. Bit.08: 1 - DO1 output control. Bit.09: 1 - DO2 output control. Bit.10: 1 - RL1 output control. Bit.11: 1 - RL2 output control. Bit.12: 1 - RL3 output control.

Low-order bits: they deﬁne the status of the controlled outputs. Bit.0 - DO1 status: 0 = inactive output, 1 = active output. Bit.1 - DO2 status: idem.

Page 99

MVW3000 | 9-11

Communication Networks

MVW3000 | 9-11

Bit.2 - RL1 status: idem. Bit.3 - RL2 status: idem. Bit.4 - RL3 status: idem.

4. Number of the parameters to be read: Through this position, the reading of any inverter parameter can be deﬁned. The number of the parameter to be read must be programmed here, and its contents will be presented at the position 4 of the variables read from the inverter.

5. Number of the parameter to be changed: (parameter contents modiﬁcation). This position operates together with the position 6, described next. When no parameter has to be changed, then ﬁll this position with the code 999.

Changing process sequence:

- Keep 999 in the position 5.

- Replace 999 by the number of the parameter to be changed.

- If no error code (124 to 127) is signalized in the Status Word, then replace the parameter number by 999, in order to conclude the modiﬁcation.

The modiﬁcation can be veriﬁed via the HMI or by reading the parameter contents.

NOTE!

1. The command to change from scalar to vector control will not be accepted if parameters P0409 to P0413 are set to zero. That should be done via HMI.

2. Do not program P0204 = 5, because in the factory default settings P0309 = Inactive.

3. P0204 and P0408 do not accept modification via network command.

4. The parameter contents must be kept by the master during 15.0 ms. Send a new value or write in another parameter only after this time has elapsed.

6. Content of the parameter to be changed, selected at the position 5: (Number of the parameter to be changed) The format of the values adjusted in this position must be the ones described in the manual. The values, however, must be written without the decimal point, if this is the case. When the parameters P409 to P413 are modiﬁed, small differences in the contents may occur when comparing the value sent via Fieldbus and the value read at the position 4. (Parameter contents) or at the HMI, because of the truncating during the reading process.

9.1.6.3 Error Indications

During the Fieldbus reading/writing process the following error indications may occur and be informed at the Status Word variable:

Status Word variable indications: A0124 - An attempt to change a parameter that can be modiﬁed only with disabled inverter.

- Parameterization error. A0125 - Caused by:

- Reading of non-existent parameter, or

- Writing on non-existent parameter, or

- Writing on P0408 and P0204. A0126 - An attempt to write a value out of the permitted range. A0127 - Caused by: a) A function selected by the Control Word has not been programmed for Fieldbus, or b) Command of a digital output that has not been programmed for Fieldbus, or c) An attempt to write in a read-only parameter.

The indication of the listed errors will be removed from the Status Word when the indented action is sent correctly, except for A127 (“b” case), whose reset is performed writing in the Control Word.

Page 100

9-12 | MVW3000

Communication Networks

9-12 | MVW3000

Example: Assuming that no digital output has been programmed for Fieldbus, then if the word 11h is written in the position 3, the inverter will respond indicating A127 in the Status Word. To remove this indication from the Status Word it is necessary:

1. To write zero in the position 3 (because no DO has been programmed for Fieldbus).

2. To change the Control Word variable so that the A127 indication be removed from the Status Word.

The removal of the listed errors from the Status Word can also be achieved by writing the 999 code in the position 5 of the variables written in the inverter. Except for A127 (“b” and “a” cases), whose reset occurs only through the writing in the Control Word, as exempliﬁed above..

NOTE!

The alarms A0124, A0125, A0126 and A0127 do not cause any change in the inverter operation status.

HMI Indications: A0129 - Inactive Fieldbus onnection This indication occurs when the physical connection from the inverter to the master is interrupted. The action that the inverter will take when A0129 is detected is programmed at P0313. The A0129 indication is removed from the display when the HMI key is pressed. E30 - Inactive Fieldbus board.

This indication will appear when:

1. P0309 is programmed different from Inactive, without the existence of the respective board mounted on the MVC4 board XC140 connector, or

2. The Fieldbus board exists but it is defective, or

3. The board exists; however, the model programmed in P0309 does not match the used board model. The action that the inverter will take when A0130 is detected is programmed at P0313. The E30 indication is removed from the display when the HMI key is pressed.

9.1.6.4 MVW3000 Variable Addressing at the Fieldbus Devices

The variables are arranged in the Fieldbus device memory from 00h on, for both writing and reading. What deals with the address differences is the protocol itself, and the communication board. The manner the variables are arranged in each address of the Fieldbus device memory depends on the equipment that is being used as master. In an A PLC, for instance, the variables are arranged High and Low, whereas in a B PLC the variables are arranged Low and High.
