CHAPTER 2

GENERAL INFORMA TION

This chapter defines the contents and purposes of this manual and describes the main characteristics of the CFW-08 frequency inverter. Identification, receiving inspections and storage requirements are also provided.

2.1 ABOUT THIS MANUAL

This Manual is divided into 10 Chapter, providing infornation to the user on how receive, install, start-up and operate the CFW-08:

Chapter 1 - Safety Notices; Chapter 2 - General Information; Chapter 3 - Installation; Chapter 4 - Start-up; Chapter 5 - Keypad HMI) Operation; Chapter 6 - Detailed Parameter Description; Chapter 7 - Diagnostic and Troubleshooting; Chapter 8 - CFW-08 Options and Accessories; Chapter 9 - Technical S pecifications; Chapter 10 - Warranty Policy.

This Manual provides information for the correct use of the CFW-08. The CFW-08 is very flexible and allows for the operation in many different modes as described in this manual.

As the CFW-08 can be applied in several ways, it is impossible to describe here all of the application possibilities. WEG does not accept any responsibility when the CFW-08 is not used according to this Manual.

No part of this Manual may be reproduced in any form, without the written permission of WEG.

2.2 SOFTWARE VERSION

It is important to note the Software V ersion installed in the V ersion CFW08, since it defines the functions and the programming parameters of the inverter. This Manual refers to the Software version indicated on the inside cover. For example, the Version 3.0X applies to versions 3.00 to 3.09, where “X” is a variable that will change due to minor software revisions. The operation of the CFW-08 with these software revisions are still covered by this version of the Manual.

The Software V ersion can be read in the Parameter P023.

GENERAL INFORMATION

2.3 ABOUT THE CFW-08

The CFW-08 is a high performance V ariable Frequency Drive that permits the control of speed and torque of a three-phase AC induction motor . T wo types of control are available in the same product:

Programmable scalar (Volts/Hz) control; Sensorless Vector Control (VVC: V oltage V ector Control).

In the vector control mode, the motor performance is optimized relating to torque and speed regulation. The "Self-Tuning" function, available in vector control, permits the automatic setting of the inverter parameter from the identification (also automatic) of the parameters of the motor connected at the inverter output. The V/F (scalar) mode is recommended for more simple applications such as pump and fan drives. In these cases one can reduce the motor and inverter losses by using the "Quadratic V/F" option, that results in energy saving. The V/F mode is also used when more than one motor should be driven simultaneously by one inverter (multimotor application).

There are two CFW-08 versions:

Standard: it has 4 digit al inputs (DIs), 1 analog input (AI) and 1 relay output. CFW-08 Plus: compared to the standard version it has one additional analog input and one additional relay output. It has also an analog output (AO).

For power ratings and further technical information, see Chaper 9.

GENERAL INFORMATION

Product Appearance

Besides the internal electronics, also the exterrnal product appearance have changed, which are:

- the frontal lettering on the plastic covers (formerly: µline, now: CFW-08 vector inverter);

- WEG logo is now indicated on all accessories of the CFW-08 line (keypad, communication modules etc).

Figure below makes a comparison:

(b) CFW-08

Figure 2.3 - Comparison between µline a CFW-08 appearance

Version of Software

The new CFW-08 starts with Software V ersion V3.00. Thus, the software Versions V1.xx and V2.xx are exclusive for µline. Besides the inverter control has been implemented in a DSP (Digital Signal Processor), which enables a more sophisticated control with more parameters and functions.

Accessories

With the migration from the 16 bits microcontroller to the DSP of the new CFW-08, the power supply of the electronic circuits had to be changed from 5V to 3.3V . Consequently , the accesories (keyp ads, communication modules, etc) of the old µline CAN NOT BE USED with the new CFW-08 line. As general rule, use only accessories with WEG logo, as already informed above.

This section aims at showing the differences between the old µline and the new CFW-08. The information below are addressed to user that are used to µline.

Table below shows the equivalence between the accessories of the old µline an the new CFW-08.

GENERAL INFORMATION

Expansion of the Power Range

The power range of the old µline (0.25-2HP) has been expanded to (0.25-10HP) with the new CFW-08 line.

Control Modes

Only the CFW-08 line has:

- Volt age Vector Control (VVC) that improves the inverter performance considerably - adding the parameters P178, P399, P400, P402, P403, P404, P407, P408 e P409;

- the quadratic curve V/F improves the systema energy saving capability when loads with quadratic torque x speed characteristics are driven, like pumps and fans.

Frequency Resolution

The new CFW-08 has a frequency resolution 10 times higher than the old µline, i.e., it has a resoltion of 0.01Hz for frequencies up to 100.0Hz and of 0.1Hz for frequencies higher than 99.99Hz.

Switching Frequencies of 10 and 15kHz

When the new CFW-08 is used, one can set the inverter switching frequency to 10 and 15kHz, which enables an extremly quiet operation. The audible noise level generated by the motor with 10 kHz is lower with the CFW-08, when compared with the µline. This is due to the PWM modulation improvements of the CFW-08.

Inputs and Outputs (I/Os)

The CFW-08 Plus line has more I/Os than the old µline, while the CFW-08 is equivalent to the µline in terms of of I/Os. See table below:

Parameters and Functions

Parameters that are already used in

µµ

µline but have been changed

a) P136 - Manual T orque Boost (IxR Compensation)

Besides the parameter name, also the way the user enters the IxR compensation value has been changed. In the old µline, the parameter P136 had a family of 10 curves (value range: 0 to

9). In the new CFW-08, the IxR Compensation is set by entering a percent (relating to the input voltage) that defines the output voltage for an output frequency equal to zero. So larger curve set and a larger variation range is obtained.

T able below shows the equivalence between which was programmed in the old µline and which must be programmed in the new CFW08 to obtain the same result.

GENERAL INFORMATION

b) Automatic T orque Boost (Automatic IxR Compensation) and Slip

Compensation

In the µline only the rated motor current (P401) was used in the Automatic IxR Compensation and the Slip Compensation functions. In the µline the rated motor power factor of the motor was considered as a fixed value and equal to 0.9 . Now in the new CFW-08, are used the parameters P401 and P407 (rated motor power factor). Thus:

Example: When in an application with the µline the following setting was required: P401=3.8A, now with the new CFW-08 you must perform the following setting: P401=3.8A and P407=0.9 or P407= rated cos ∅ of the used motor and P401=3.8 x

0.9

P407

Parameters existing only in Special Software Versions of the

µµ

µline

a) Quick Inputs

In the new CFW-08, the response time of the the digital inputs is 10ms (max.). In addition, the minimum acceleration and deceleration time was reduced from 0.2s (µline) to 0.1s (CFW-08). Besides the DC braking process can be interrupted before it has been concluded, for instance, when a new enabling is required.

b) Other changes

P120=2 - digital reference backup via P121 independently of the reference source. P265=14 - DI3: multispeed using ramp #2.

New Parameters and Functions

The reference 1 of the multispeed that was in Parameter P121 (in µline) is now in Parameter P124 (in CFW-08). The DC link regulation level (ramp holding) can now be programmed in Parameter P151 - in the µline this level was fixed to 377V for the 200-240V line and 747V for the 380-480V line. Also the programming way of Parameter P302 has changed. In the µline P302 was related to the voltage applied to the output during the D Cbraking, now in the new CFW-08, P302 defines the DC Braking Current. PID regulator. Suammarizing, the new parameters are: P009, P040, P124, P151, P178, P202, P203, P205, P219, P238, P239, P240, P251, P252, P279, P399, P400, P402, P403, P404, P407, P408, P409, P520, P521, P522, P525, P526, P527 e P528.

HOW TO SPECIFY THE CFW-08 MODEL:

GENERAL INFORMATION

2.5 Receiving and Storing

NOTE!

The Option field (S or O) defines if the CFW-08 is a standard version or if it will be equipped with any optional devices. If the standard version is required, the specification code ends here. The model number has always the letter Z at the end. For example:

CFW080040S2024ESZ = standard 4.0A CFW-08 inverter, single-phase at 200...240V input with manual in English.

For the effect of this code, the standard product is conceived as follows:

- CFW-08 with standard control board.

- Degree of protection: NEMA 1 for the models 13 and 16A/380-480V; IP20 for the other models.

If the CFW-08 is equipped with any optional devices, you must fill out all fields in the correct sequence up to the last optional device, the model number is completed with the letter Z. It is not necessary to indicate the code number 00 for those optional devices that are standard or that will not be used.

Thus, for instance if the product above is required with NEMA 1 degree of protection: CFW080040S2024EON1Z = CFW-08 inverter, 4A, single-phase,

200...240V input, with manual in English language and with kitf fo r

NEMA 1 degree of protection. The CFW-08 Plus is formed by the inverter and the control board 1.

Example: CFW080040S2024EOA1Z.

7.0 and 16.0A/200-240V and for all 380-480V models are just available

with three-phase power supply. A RFI Class A filter (optional) can be installed inside the inverter in

models 7.3 and 10A/200-240V (single-phase) and 2.7, 4.3, 6.5, 10, 13 and 16A/380-480V . Models 1.6, 2.6 and 4.0A/200-240V (single-phase) and 1.0, 1.6, 2.6 and 4.0A/380-480V can be provided mounted on a footprint RFI Class A filter (optional).

The listing of the existing models (voltage/current) is shown in item 9.1.

The CFW-08 is supplied in cardboard boxes. The outside of the packing box has a nameplate that is identical to that on the CFW-08. Please check if the CFW-08 is the one you ordered. Check if the:

CFW-08 nameplate data matches with your purchase order . The equipment has not been damaged during transport.

If any problem is detected, contact the carrier immedately . If the CFW-08 is not installed immediately, store it in a clean and dry room (storage temperatures between –25°C and 60°C). Cover it to protect it against dust, dirt or other contamination.

CHAPTER 3

ATTENTION!

The AC input for the inverter must have a grounded neutral conductor .

NOTE!

The AC input voltage must be comp atible with the inverter rated voltage. The requirements for use of line reactors depends on several application factors. Refer to Section 8.15. Capacitors for power factor correction are not required at the input (L/L1, N/L2, L3 or R, S, T ) and they must not be connected at the output (U, V and W). When inverters with dynamic braking (DB) are used, the DB resistor shall be mounted externally . Figure 8.21 shows how to connect the braking resistor. Size it according to the application, not exceeding the maximum current of the braking circuit. For the connection between inverter and the braking resistor, use twisted cable. Provide physical separation between this cable and the signal and control cables. When the DB resistor is mounted inside the panel, consider watt loss generated when the enclosure size and required ventilation are calculated. When electromagnetic interference (EMI), generated by the inverter, interfers in the performance of other equipment, use shielded wires, or install the motor wires in metallic conduits.Connect one end of the shielding to the inverter grounding point and the other end to the motor frame. Always ground the motor frame. Ground the motor in the p anel where the inverter is installed or ground it to the inverter . The inverter output wiring must be laid separately from the input wiring as well as from the control and signal cables. The inverter is provided with electronic protection against motor overload. This protection must be set according to the specific motor. When the same inverter drives several motors, use individual overload realays for each motor. Maint ain the electrical continuity of the motor cable shield. If a disconnect switch or a contactor is inserted in the motor supply line, do not operate them with motor running or when inverter is enabled. Maintain the electrical continuity of the motor cable shield. Use wire sizing and circuit breakers as recommended in Table 3.3. Tightening torque is as indicated in T able 3.4. Use (70ºC) copper wires only .

INSTALLATION AND CONNECTION

NOTE!

Supply line capacity: The CFW-08 is suitable for use in circuits capable of supplying not more than symmetrical 30.000Arms (240/480V). The CFW-08 can be installed on power supplies with a higher fault level if an adequate protection is provided by fuses or circuit breaker.

NOTE!

Jumpers S1 are factory set to OFF position (0 ... 10V signal). If it's used a 4 ... 20mA signal, set parameter P235 and/or P239, that defines the signal type at AI1 and AI2, respectively . The parameters related to the analog inputs are: P221, P222, P234, P235, P236, P238, P239 e P240. For more details, please refer to Chapter 6.

During the signal and control wire installation note please the following:

1) Cable cross section: 20 ... 14 A WG (0.5...1.5mm²).

2) Max. T orque: 0.50 N.m (4.50 lbf.in).

3) XC1 wiring must connected with shielded cables and installed separately at a distance of 10 cm each other for lengths up to 100m and at distance of 25cm each other for lengths over 100m. If the crossing of these cables is unavoidable, install them perpendicular , maintaining a mimimum separation distance of 2 in (5 cm) at the crossing point.

Connect the shield as shown below:

Insulate with tape

4) For wiring distances longer than 150 ft ( 50 m), it's necessary to use galvanic isolators for the XC1:5...9 analog signals.

As a default the analog input(s) is(are) selected as 0...10V . This can be changed using dip switch S1 on the control board and parameters P235 and P239 (see note below).

INSTALLATION AND CONNECTION

5) Relays, contactors, solenoids or eletromagnetic braking coils installed

near inverters can generate interferences in the control circuit. T o eliminate this interference, connect RC suppressor in parallel with the coils of AC relays. Connect free-wheeling diode in case of DC relays.

6) When external keypad (HMI) is used (refer to Chapter 8), separete

the cable that connects the keypad to the inverter from other cables, maintaining a minimum distance of 4 in (10 cm) between them.

7) When analog reference (AI1 or AI2) is used and the frequency

oscillates (problem caused by eletromagnetic interference) connect XC1:5 to the inverter heatsink.

3.2.5 Typical T erminal Connections

Connection 1 - Keypad Start/Stop (Local Mode) With the factory default programming, you can operate the inverter in

local mode with the minimum connections shown in Figure 3.4 (Power)

and without control connections. This operation mode is recommended for users who are operating the inverter for the first time. Note that there is no need of connection of control terminals.

For start-up according to this operation mode, refer to Chapter 4.

Connection 2 - 2-Wire Start/Stop (Remote Mode) V alid for factory default programming and inverter operating in remote

mode. For the factory default programming, the selection of the operation

mode (local/remote) is made via the key (default is local).

INSTALLATION AND CONNECTION

3.3 European EMC Directive Requirements for Conforming Installations

The CFW-08 inverter series was designed considering safety and EMC (ElectroMagnetic Compatibility) aspects. The CFW-08 units do not have an intrinsic function until connected with other components (e. g. a motor). Therefore, the basic product is not CE marked for compliance with the EMC Directive. The end user takes personal responsibility for the EMC compliance of the whole installation. However, when installed according to the recommendations described in the product manual and including the recommended filters and EMC measures the CFW-08 fulfill all requirements of the EMC Directive (89/336/EEC) as defined by the EMC Product Standard for Adjustable Speed Electrical

Power Drive Systems EN61800-3.

Compliance of the CFW-08 series is based on the testing of the representative models. A Technical Construction File was checked and approved by a Competent Body.

3.3.1 Installation

Figure 3.15 below shows the EMC filters connection.

Figure 3.15 - EMC filters connection - general condition

The following items are required in order to have a conforming installation:

1) The motor cable must be armored, flexible armored or installed inside a metallic conduit or trunking with equivalent attenuation. Ground the screen/ metallic conduit at both ends (inverter and motor).

2) Control (I/O) and signal wiring must be shielded or installed inside a metallic conduit or trunking with equivalent attenuation.

3) The inverter and the external filter must be mounted on a common metallic back plate with a positive electrical bond and in close proximity to one another. Ensure that a good electrical connection is made between the heatsink (inverter) / frame (external filter) and the back plate.

4) The length of the wiring between filter and inverter must be kept as short as possible.

5) The cable’s shielding must be solidly connected to the common back plate, using a metal bracket.

6) Grounding as recommended in this manual.

7) Use short and thick earthing cable to earth the external filter or inverter. When an external filter is used, only use an earth cable at filter input the inverter earth connection is done by the metallic back plate.

8) Earth the back plate using a braid, as short as possible. Flat conductors (e.g. braids or brackets) have lower impedance at high frequencies.

9) Use cable glands whenever possible.

INSTALLATION AND CONNECTION

Obs.:

1) Category II systems must be mounted inside a metallic cabinet in order to have radiated emissions below the limits for first environment and restricted distribution (see item 3.3.3). Category I systems do not require a metallic cabinet. Exception: models 7 and 8, that need to be mounted inside a cabinet to pass in the radiated emission test for second environment and unrestricted distribution (see item 3.3.3). When a metallic cabinet is required, the maximum length of the remote keypad cable is 3m. In this case, the control (I/O) and signal wiring must be located inside the cabinet and the remote keypad can be installed in the cabinet front door (see items 8.3.1 and 8.5).

2) The maximum switching frequency is 10kHz. Exception: 5kHz for models 24 up to 33 (category I, 380-480V models). For category I systems see also note 7.

3) The maximum motor cable length is 20m for models 9, 10, 1 1, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 34, 35, 36 and 37, 10m for models 1, 2, 3, 4, 5, 6, 7, 8, 24, 25, 26, 27, 38, 39, 40, 41, 42 and 43 and 5m for models 28, 29, 30, 31, 32 and 33. For category I systems see also note 7.

4) In models 28, 29, 30 and 31 (see also note 7), a CM choke at inverter output is required: TOR1-CFW08, 1 turn. The toroid is mounted inside the N1 kit that is provided with these models. For installation see figure

3.15.

5) In models 38, 39, 40, 41, 42 and 43, a CM choke at filter input is required: TOR2-CFW08, 3 turns. For installation see figure 3.15.

6) In models 38, 39, 40 and 41, it is required to use a shielded cable between the external filter and the inverter.

7) Category I systems were also tested using second environment unrestricted distribution limits for conducted emissions (for definitions see notes 2 and 3 of item 3.3.3). In this case:

- the maximum cable length is 30m for models 1, 2, 3, 4, 5, 6, 7, 8,

32 and 33 and 20m for models 24, 25, 26, 27, 28, 29, 30 and 31;

- the maximum switching frequency is 10kHz for models 28, 29, 30

and 31 and 5kHz for models 1, 2, 3, 4, 5, 6, 7, 8, 24, 25, 26, 27, 32 and 33;

- models 28, 29, 30 and 31 do not require any CM choke at inverter

output (as stated in note 4).

4.1 PRE-POWER CHECKS

This Chapter provides the following information:

how to check and prepare the inverter before power-up; how to power-up and check for proper operation; how to operate the inverter when it is installed according to the typical connections (refer to Section 3.2 - Electrical Installation).

The inverter shall be installed according to Chpater 3 - Installation and Connection. If the drive project is different from the typical suggested connections, follow the procedures below.

DANGER!

Alaways disconnect the AC input power before making any connections.

1) Check all connections

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

2) Check the motor

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

4) Uncouple the load from the motor

If the motor can not be uncoupled, make sure that the direction of rotation (FWD/REV) can not cause damage to the machine.

4.2 INITIAL

POWER-UP

After the inverter has been checked, AC power can be applied:

1) Check the power supply

Measure the line voltage and check if it is within the specified range (rated voltage: + 10% / - 15%).

2) Power-up the AC input

Close the input circuit breaker or disconnect switch.

3) Check if the power-up has been succesful

- Inverter with keypad (HMI-CFW08-P or HMI-CFW08-RS)

The keypad display will show:

The four LEDs of the keypad remains ON during this procedure. Inverter runs some self-diagnosis routines. If no problems are found, the display shows:

This means that the inverter is ready (rdy = ready) to be operated.

- Inverter with dummy panel (TCL-CFW08 or TCR-CFW08).

The LEDs ON (green) and ERROR (red) are ON. Inverter runs some self-diagnosis routines. If no problems are found the LED ERROR (red) turns OFF . This means that the inverter is now ready to be operated.

DANGER!

Even after the AC power supply has been disconnected, high voltages may be still present. Wait at least 10 minutes after powering down to allow full discharge of the capacitors.

The sequence below is valid for the connection 1 (refer to Section 3.2.5). Inverter must be already installed and powered up according to Chapter 3 and Section 4.2.

This Section describes start-up procedures when operating via the keypad (HMI). T wo types of control will be considered:

V/F and Vetor Control

The V/F control is recommended in the following cases:

several motors driven by the same inverter; rated current of the motor is lower than 1/3 of rated inverter current

for test purposes, inverter is start-up without load. The V/F control can also be used in applications that do not require fast dynamic responses, accurate speed regulations or high starting torque (speed error will be a function of the motor slip); when you program parameter P138 - rated slip - you can obtain a speed accuracy of 1%. For the most applications, we recommend the vector control mode, that permits a higher speed control accuracy (typical 0.5%), higher starting torque and a faster dynamic response.

START-UP

NOTE!

The last frequency reference (speed) vale set via the and keys is saved.

If you wish to change this value before inverter enabling, change parameter P121 (Keypad Reference).

NOTES:

(1 ) If the direction of rotation of the motor is not correct, switch off the

inverter. W ait at least for 10 minutes to allow complete capacitor discharge and then swap any two wires at the motor output.

(2) If the acceleration current becomes too high, mainly at low frequencies,

set the torque boost (IxR compensation) at P136. Increase/decrease the content of P136 gadually until you obtain an operation with constant current over the entire frequency range. For the case above, refer to Parameter Description in Chapter 6.

(3 ) If E01 fault occurs during deceleration, increase the deceleration time

at P101 / P103.

NOTE!

The last speed reference value set via key and keys is saved. If you wish to change this value before enabling of inverter, change the value of the Parameter P121 - Keypad Reference; The self-tuning routine can be cancelled by pressing the key.

NOTES:

(1) If during the running of the Self-Tuning Routine the display shows E14,

this means that the motor parameters were not acquired correctly by the inverter. The most common reason for this fault may be that the motor has not been coupled to the inverter output. However motors with very lower currents than the used inverter, or incorrect motor connection may also cause the fault E14. In this case, operate the inverter in V/F mode (P202=0). When the motor is not connected and the fault condition E14 is indicated, proceed as follows:

Switch off the inverter. W ait at least 5 minutes to allow a complete discharge of the capacitors. Connect the motor to the inverter output. Switch on the inverter. Set P000=5 and P408=1. Follow from now on the start-up procedures described in Section 4.3.3.

(2) For each inverter type, the parameters P399...P407 are set automatically

to the rated motor data, considering a standard WEG motor, IV poles, 60Hz. When different motors are used, you must set the parameters manually, according to the motor nameplate data.

(3) If the direction of rotation of the motor is not correct, switch off the inveter.

Wait at least 5 minutes to allow a complete discharge of the capacitors and then swap any two wires at the motor output.

(4) If fault E01 occurs during deceleration, you must increase the deceleration

time at P101/P103.

KEYPAD (HMI) OPERATION

5.2.1Keypad Operation

All functions relating to the CFW-08 operation (Start/Stop, Direction of Rotation, JOG , Increment/Decrement of the S peed (Frequency) Reference, and selection of LOCAL/REMOTE mode) can be performed through the HMI selection. For factory default programming of the inverter, all keyp ad keys are enabled when the LOCAL Mode has been selected. These same functions can be performed through digital and analog inputs. Thus you must program the parameters related to these corresponding inputs.

NOTE!

The control keys , and are only enabled if:

P229=0 for LOCAL Mode operation P230=0 for REMOTE Mode operation

The key depends of the parameters above and if:

P231=2 Keypad keys operation description: When enabled (P220 = 2 or 3), selects the control input and the speed

reference (speed) source, toggling between LOCAL and REMOTE Mode. When pressed, starts the motor according to acceleration ramp up to the

speed (frequency) reference. The function is similar to that performed through digital input ST ART/STOP, when it is closed (enabled) and maintained enabled.

Stop disables the inverter via deceleration Ramp.The Function is similar to that performed through digital input START/STOP, when it is open (disabled) and maintained disabled.

When the JOG key is pressed, it accelerates the motor according to the acceleration ramp up to the JOG speed programmed in P122. This key is only enabled when the inverter digital inputs, programmed to general enable (if any) are closed.

When enabled (refer to the note above), reverses the motor direction of rotation.

Motor speed (frequency) setting: these keys are enabled for speed setting only when:

the speed reference source is the keypad (P221 = 0 for LOCAL Mode

and/or P222 = 0 for REMOTE Mode);

the following parameter content is displayed: P002, P005 or P121. Parameter P121 stores the speed reference set by these keys. When pressed, it increases the speed (frequency) reference. When pressed, it decreases the speed (frequency) reference.

KEYPAD (HMI) OPERATION

Inverter is READY to be started.

Line voltage is too low for inverter operation (undervoltage condition).

Inverter is in a Fault condition. Fault code is flashing on the display. In our example we have the fault code E02 (refer to chaper Maintenance).

Inverter is applying a DC current on the motor (DC braking) according to the values programmed at P300, P301 and P302 (refer to Chapter 6).

Inverter is running self-tuning routine to identify motor parameters automatically . This operation is controlled by P408 (refer to Chapter 6).

5.2.2 Inverter Status

5.2.3Read-Only Variables

NOTE!

The display also flashes in the following conditions, besides the fault conditions:

trying to change a parameter value when it is not allowed. inverter in overload condition (refer to Chapter Maintenance).

Parameters P002 to P099 are reserved for the display of read-only values. The factory default display when power is applied to the inverter is P002 (frequency proportional value in V/F control mode and motor speed in rpm in vector control mode). Parameter P205 defines the initial monitoring parameter , i.e., defines the read-only variable that will be displayed when the inverter is powered up. For further information refer to P205 description in Chapter 6.

Reference Backup

The last frequency reference set by the keys the and is stored when inverter is stopped or the AC power is removed, provided P120 = 1 (reference backup active is the factory default). T o change the frequency reference before starting the inverter, the value of the p arameter P121, must be changed.

KEYPAD (HMI) OPERATION

NOTE!

(1 ) For parameters that can be changed with the motor running, the

inverter will use the new value immediately after it has been set. For parameters that can be changed only with motor stopped, the inverter will use this new value only after the key is pressed.

(2) By pressing the key after the reprogramming, the new

programmed value will be stored automatically and will remain stored until a new value is programmed.

5.2.4Parameter Viewing and Programming

All CFW-08 settings are made through parameters. The parameter are shown on the display by the letter P followed by a number: Exmple (P101):

101 = Parameter Number

Each parameter is associated with a numerical value (parameter value), that corresponds to the selected option among the available ones for this parameter .

The parameter values define the inverter programming or the value of a variable (e.g.: current, frequency , voltage).For inverter programming you should change the parameter content(s).

T o allow the reprogramming of any parameter value (except for P000 and P121) it is required to set P000 = 5. Otherwise you can only read the parameter values, but not reprogram them. For more details, see P000 description in Chapter 6.

This section describes the main concepts related to the CFW-08 frequency inverter.

As already informed in section 2.3, CFW-08 has in the same product a V/F control and a sensorless vector control (VVC: “voltage vector control”). The user must choose one of them. Please find below a description of each control mode.

This control mode is based on the constant V/F curve(P202=0 - linear V/ F curve). Its performance is limited at low frequencies as function of the voltage drop in the stator resistance, that causes a significant magnetic flow reduction in the motor air gap and consequently reducing the motor torque. This deficiency should be compensated by using manual and automatic boost torque (IxR compensations), that are set manually and depend on the user experience. In most applications (for instance: centrifugal pumps and fans) the setting of these functions is enough to obtain the required performance. But there are applications that require a more sophisticated control. In these cases it´s recommended the use of the sensorless vector control, that will be described in the section below. In V/F control, the speed regulation, that can be obtained by setting properly slip compensation can be maintained within 1 to 2% of the rated speed. For instance, for a IV pole motor/60Hz, the minimum speed variation at no load condition and at rated load can be maintained between 18 and 36rpm.

6.2 INTRODUCTION

6.2.1Control Modes

6.2.2 V/F Control

DET AILED P ARAMETER DESCRIPTION

CHAPTER 6

DETAILED PARAMETER DESCRIPTION

There is still a variation of the linear V/F control: the quadratic V/F control. This control mode is suitable for applications like centrifugal pumps and fans (loads with quadratic torque x speed characteristics), since it enables a motor loss reduction, resulting in an additional energy saving by using an inverter. For more details about the V/F control mode, please refer to the description of the parameters P136, P137, P138, P142 and P145.

Inverter performance improvements can be achieved when the sensorless vector control is selected (P202=2). The CFW-08 vector control is sensorless, i.e., it does not require a signal of the speed feedback through tachogenerator or encoder coupled on motor shaft. To maintain the magnetic flow in the motor air gap constant, and consequently the motor torque, within the whole speed variation range (from zero up to the field weakening point), a sophisticated control algorithm is used that considers the mathematic model of the induction motor. Thus one can maintain the mangetic flow in the motor air gap approximately constant at frequencies down to approximately 1 Hz. In vector control mode one can obtain a speed regulations about 0.5% (relating to the rated speed). Thus, for instance, for a IV pole motor/60Hz one can obtain a speed variation in the range of 10rpm (!). Other advantage of the vector control is its easy setting procedure. The user needs only to enter in the parameters P399 and 407 the information about the used motor (nameplate data) and runs the self-tuning routine (by setting P408=1) and the inverter configures itself to the required application. So the inverter is ready to be operated in an optmized manner. For more information, refer to the description of the following parameters: P178 and P399 to P409.

The frequency reference (i.e., the desired output frequency , or alternatively, the motor speed) can be defined in several ways:

the keypad - digital reference that can be changed through the keypad (HMI), by using the keys and (see P221, P222 and P121); analog input - the analog input AI1 (XC1:6) or the AI2 (XC1:8) can be used, or both (see P221, P222 and P234 to P240); multispeed - up to 8 preset digital references (see P221, P222 and P124 to P131); electronic potentiometer (EP) - another digital reference, its value is defined by using 2 digital inputs (DI3 and DI4) - see P221, P222, P265 and 266; via serial.

Figure 6.1 shows through a diagram block the frequency reference definition to be used by the inverter. The block diagram in Figure 6.2 shows the inverter control.

DETAILED PARAMETER DESCRIPTION

6.2.5Commands

6.2.6Local/Remote Operation Modes

The inverter has the following commands: PWM pulse enabling/disabling, definition of the direction of rotation and JOG . As the reference, the inverter commands can de defined in several ways.

The command sources are the following:

via keypad - keys , , and ; via control terminals (XC1) - digital inputs; via serial interface.

The inverter enabling and disabling commands can be defined as follows:

via keypad and of the HMI; via serial; start/stop (terminals XC1 - DI(s) - see P263 ... P266); general enable (terminals XC1 - DI(s) - see P263 ... P266); forward run It defines also the direction of rotation; ON/OFF (3-wire controls) (terminals XC1 - DIs - see P263 e P264).

The definition of the direction of rotation can be defined by using:

the key of the keypad; serial; digital input (DI) programmed for FWD/REV (see P264 ... P266); digital inputs programmed as FWD / REV , that defines both inverter enabling or disabling and direction of rotation (see P263 e P264); analog input - when the reference is via analog input and a negative offset is programmed (P236 or P240<0), the reference may assume negative values, thus reversing the direction of the motor rotation.

User can define two different conditions relating to the frequency reference source and the inverter commands: these are the local and the remote operation modes. Figure 6.3 shows the local and remote operation modes in a block diagram. With the factory setting in local mode the inverter can be controlled by using the keypad, while in remote mode all controls are via terminals (XC1).

This set of parameters defines the time to accelerate linearly from zero up to the rated frequency and to decelerate linearly from the rated frequency down to zero. The rated frequency is defined by parameter:

- P145 in V/F control (P202=0 ou 1);

- P403 in vector control (P202=2). When factory setting is used, inverter always follows the time defined in P100 and P101. Ramp #2 is used , the the acceleration and deceleration times follow the values programmed at P102 and P103, use a digital input. See parameters P263 ... P265. Depending on the load inertia, too short acceleration times can disable the inverter due to overcurrent (E00). Depending on the load inertia, too short deceleration times can disable the inverter due to overvoltage (E01). For more details, refer to P151.

The direction of rotation is defined by parameter P231.

DETAILED PARAMETER DESCRIPTION

Multispeed is used when the selection of a number up to 8 preprogrammed speeds is desired. It allows the control of the output speed by relating the values programmed by the parameters P124...P131, according to the logical combination of the digital inputs programmed for multispeed. Activation of the multispeed function:

- ensure that the reference source is given by the multispeed function, i.e., set P221=6 in local mode or P222=6 in remote mode;

- program one or more digital inputs to para multispeed, according to table below:

DI Programming DI2 P264 = 7 DI3 P265 = 7 DI4 P266 = 7

The frequency reference is defined by the status of the digital inputs programmed to multispeed as shown in table below:

The multispeed function has some advantages for the stabibilty of the fixed preprogrammed references and the immunity against electrical noises (digital references and insulated digital inputs).

Define the V/F curve used in V/Fcontrol (P202=0 or 1). These parameters allow changing the standard V/F curve defined at P202 - programmable V/F curve. P142 sets the maximum output voltage. This value is set as a percent of the inverter supply voltage. Parameter P145 defines the rated frequency of the motor used. The V/F curve relates the inverter output voltage and frequency (applied to the motor) and consequently the magnetizing flux of the motor. The programmave V/F curve can be used in special applications where the motors used require a rated voltage and/or frequency different than the standard ones. Examples: motor for 220V/ 400Hz and a motor for 200V/60Hz. Parameter P142 is also useful in appplications that require rated voltage different from the inverter supply voltage.

By this function an optimized deceleration time (minimum) is achieved for the driven load. This function is useful in applications with medium inertia that require short deceleration times. In case of overvoltage trip during the decelearation, you must reduce gradually the value of P151 or increase the time of the deceleration ramp (P101 and/or P103). The motor will not stop if the line is permanently with overvoltage (Ud>P151). In this case, reduce the line voltage, or increase the value of P151. If even with these settings the motor does not decelerate within the required time, you will have the following alternatives

- use the dynamic braking (for more details, see Item 8.20);

- if inverter is being operated in V/F control, increase P136;

- if inverter is being operated in vector control, increase P178.

- to increase the inverter torque capacity (P178>100%). Examples:

1)to increase the motor starting torque and thus ensure faster motor starts;

2 ) to increase the inverter braking torque and thus allow faster

stops, without using dynamic braking.

Type of Control [ 0 - V/F linear ]

As shown in table above, there are 2 V/F control modes:

- Linear V/F control: this control mode ensures a flux in the motor air gap approximately constant from around 3Hz up to the field weakening (defined by the parameters P142 and P145). Thus in this speed range, an approximately constant torque capacity is obtained. This control mode is recommended for belt conveyors, extruding machines, etc.

- Quadratic V/F control: in this control mode the flux in the motor air gap is proportional to the output frequency up to the field weakening point (defined at P142 and P145). Thus the torque capacity is a function of the quadratic speed. The main advantage of this type of control is the energy saving capability with variable torque loads, due to the reduction of the motor losses (mainly due to motor iron losses and magnetic losses).

Main application fields for this type of control are: centrifugal pumps, fans, multimotor drivings.

The vector control allows a better performance regarding to torque and speed control. The CFW-08 vector control operates without motor speed sensor (sensorless). It must be applied when following performances are required:

- better dynamics (faster accelerations and stoppings);

- when a more accurate speed control is required;

- when high torques at low speeds are required ( 5Hz). Examples: in positioning, such as load moving, packing machines, pumps, dosing machines, etc. The vector control can not be used in multimotor applications.

The performance of the vector control with a switching frequency of

10kHz is not so good as when a switching frequency of 5kHz or

2.5kHz is used. It is not possible to use a vector control with a switching frequency of 15kHz. For more details about the vector control, refer to Item 6.2.3.

This parameter can be changed only with the inverter disabled (motor stopped).

Procedure is as follows:

1. Connect the keypad (HMI-CFW08-RS) to the inverter from which the parameters willl be copied (Inverter A - source inverter).

2. Set P215=1 (copy) to transfer the parameter values from the inverter A to the keypad. Press key. During running of the

3. Disconnect the keypad from the inverter (A).

4. Concect the same keypad to the inverter to which the parameters will be transferred (Inverter B - target inverter).

5. Set P215=2 (paste) to transfer the content of the of the keypad (EEPROM has the inverter A parameters) to inverter B. Press the key. While the keypad is running the paste function, the display shows , an abbreviation for paste.

When P215 returns to 0, the parameter transfer has been concluded. Now inveters A and B will have the same parameter values.

It allows that the read-only parameter P002 indicates the motor speed in value, for instance, rpm. The indication of P002 is equal to the output frequency value (P005) multiplied by the value of P208, i.e., P002 = P208 x P005. If desired, the conversion from Hz to rpm is made as a function of the pole number:

- otherwise no function is associated to the input DI3/DI4.

4) The selection of P265=P266=5 (EP) requires the programming of P221 and/or P222=4.

5) The selection of P264 and/or P265 and/or P266=7 (multispeed) requires the programming of P221 and/or P222=6.

Parameter Unit Description / Notes

Thus, P297=4 (5kHz) results in an audible motor noise corresponding to 10kHz. This is due to the used PWM technique . The reduction of the switching frequency also contributes to the reduction of instability and ressonance that may occur in certain application conditions, as well as reduces the emission of electromagnetic energy by the inveter. The reduction of the switching frequencies also reduces the leakage currents to ground, which may avoid the nuisance activation of the ground fault protection (E00). The option 15kHz (P297=7) is not available in vector control mode. Use currents according to table below:

The switching frequency is a comprimise between the motor acoustic noise level and the inverters IGBTs losses. Higher switching frequencies cause lower motor acoustic noise level, but increase the IGBT slosses, increasing the drive components temperature and thus reducing their useful life. The predominant frequency on the motor is twice the switching frequency setat P297.

Before DC braking starts, there is a "Dead Time" (motor runs freely) required for the motor demagnetization. This time is function of the motor speed at which the DC braking occurs. During the DC braking the LED display flashes .

If the inverter is enabled during the braking process, this process will be aborted and motor operates normally . DC braking can continue its braking process even after the motor has stopped. Pay special attention to the dimensioning of the motor thermal protection for cyclic braking of short times.

Parameter P31 1 sets the time required for the motor restart, both for flying start function and the ride-through function. In other words, it defines the time to set the output voltage starting from 0V and up to reaching the rated voltage. Operation of the flying start function:

- It allows the motor to start when it is running. This functions acts only when the inverter is enabled. During the start, the inverter will impose the speed reference, creating a voltage ramp with time defined at P31 1.

- The motor can be started in conventional form, even when the flying start has been selected (P310=1 or 2), adjusting one of the digital inputs (D13 or D14) to 13 (flying start disable) and driving it (0V) during the motor start.

Ride-Through operation:

- Permits the inverter recovery , without disabling by E02 (undervoltage), when a momentary voltage drop in the line occurs. The inverter will be disabled only by E02, if the voltage drop is longer than 2.0s.

- When the ride-through function is enabled (P310=2 or 3) and if a voltage drop in the line occurs, so the link circuit voltage becomes lower than the permitted undervoltage level, the output pulses will be disabled (motor runs freely) and the inverter waits up to 2s for the line re-establishment. If the line returns to is normal status within this time, the inverter will enable again the PWM pulses , imposing the frequency reference instantaneously and providing a voltage ramp with time defined at P31 1.

- There is a dead time before this voltage ramp is started, required for the motor demagnetization. This time is proportional to the output frequency (motor speed).
