CHAPTER 2

CHAPTER 2 - GENERAL INFORMATION

2.3 ABOUT THE CFW-10

The CFW-10 frequency inverter is fitted with the V/F (scalar) control method. The V/F (scalar) mode is recommended for more simple applications such as pump andfan 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). Chapter 9 shows the different power lines and additional technical information The block diagram below gives a general overview of the CFW-10.

Avoid direct exposure to sunlight, rain, high moisture and sea air. Avoid exposure to gases or explosive or corrosive liquids; Avoid exposure to excessive vibration, dust, oil or any conductive particles or materials.

Environmental Conditions:

Temperature : 0 ºC to 50 ºC (32 ºF to 122 ºF) - nominal conditions, except for the 15.2 A model with Built-in filter (0 to 40 °C). Relative Air Humidity: 5 % to 90 % - non-condensing. Maximum Altitude: 1000 m (3.300 ft) - nominal conditions. From 1000 m to 4000 m (3.300 ft to 13.200 ft): with 1 % current derating for each 100 m (330 ft) above 1000 m (3.300 ft). Pollution Degree: 2 (according to EN50178 and UL508C).

External dimensions and mounting holes for the CFW-10 shall be according to figure 3.1 and table 3.1.

DANGER!

Use a disconnecting device at the drive AC-input power supply. This device shall be capable of disconnecting the drive from the power supply when necessary (for maintenance purposes, for instance).

ATTENTION!

The drive AC-input power supply shall have a grounded neutral conductor.

NOTE!

The AC-input voltage shall match the drive rated voltage.

Supply line capacity:

The CFW-10 is capable of withstanding up to 30.000 symmetrical rms Amperes at 127 V/240 V. If the CFW-10 is installed in networks with higher symmetrical rms currents (> 30.000 Amps), an appropriate protection mean shall be provided (fuses or circuit breaker).

Line Reactors

The use of line reactors is dependent upon several factors. Refer to Chapter 8.2 in order to understand these requirements.

NOTE!

Capacitors for power factor correction are not required at the input (L/L1, N/L2, L3) and shall not be connected at the output (U, V, W ).

3.2.4.1 AC Input Connection

CHAPTER 3 - INSTALLATION AND CONNECTION

Rheostatic Braking

For the drives with the rheostatic braking optional, the braking resistor shall be installed externally. Refer to figure 8.4 for correct braking resistor installation. Size the braking resistor according to the application and respecting the maximum admissible current for the braking circuit. Use twisted pair to connect the braking resistor to the drive. Run this cable separately from the signal and control cables. If the braking resistor is installed inside the drive panel, the additional resistor heat dissipation shall be considered when defining the panel ventilation.

DANGER!

The drive must be grounded for safety purposes (PE). The ground connection must comply with the local regulations. For grounding purposes, use cables with cross sections as indicated in table 3.3. Make the ground connection to a grounding bar or to the general grounding point (resistance  10 ohms).

DANGER!

The grounding wiring shall be installed away from equipment operating with high currents (for instance: high voltage motors, welding machines, etc). If several drives are used together, refer to figure 3.7.

3.2.4.3 Grounding Connections

3.2.4.2 Output Connection

The drive has electronic protection against motor overload. This protection shallbe set according to the specific motor. W hen the same drive is connected to several motors, individual overload relays shall be used for each motor protection.

ATTENTION!

If a disconnecting switch or a contactor is inserted between the drive output and the motor input, do not operate them when motor is running or when drive is enabled. Maintain the electrical continuity of the motor cable shield.

CHAPTER 3 - INSTALLATION AND CONNECTION

NOTE!

Do not use the neutral conductor for grounding purposes.

ATTENTION!

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

Electromagnetic Interference (EMI)

Shielded cableor metallic conduit shall be used for motor wiring when electromagnetic interference (EMI) caused by the drive interferes in the performance of other equipment. Connect oneend of the shielding to the drive grounding point and the other end to the motor frame.

Motor Frame

Always ground the motor frame. Ground the motor in the panel where the drive is installed or ground it to the drive. The drive output wiring must be laid separately from the input wiring as well as from the control and signalcables.

4) For wiring distances longer than 50 m (150 ft), the use of galvanic isolators is required for the XC1:6 to XC1:9 analog signals.

5) Relays, contactors, solenoids or eletromagnetic braking coils installed near inverters can eventually generate interferences in the control circuit. To 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 analog reference (AI1) is used and the frequency oscillates (problem caused by electromagnetic interference) connect XC1:7 to the inverter grounding bar.

During the signal and control wire installation note the following:

1) Cable cross section: (0.5 to 1.5) mm² / (20 to 14) AWG.

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

3) XC1 wiring must be connected with shielded cables and installed at least 10 cm (3.9 in) minimum separately from other wiring (power, control at 110/220 V, etc) for lengths up to 100 m (330 ft) and 25 cm (9.8 in) minimum for total lengths over 100 m (330 ft). If t he crossing of these c ables is unavoidable, install them perpendicular, maintaining a mimimum separation distance of 5 cm (2 in) at the crossing point.

Connect the shield as shown below:

The CFW-10 inverter series was designed considering all safety and EMC (ElectroMagnetic Compatibility) aspects. The CFW-10 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 ins tallation. H owever, when ins talled accor ding t o th e recommendations described in the product manual and including the recommended filters and EMC measures the CFW -10 fulfill all requirements of the (EMC Directive 89/336/EEC) as defined by the

EN61800-3 "EMC Product Standard for Adjustable Speed Electrical Power Drive Systems - specific standard for variable

speed drives. The conformity of the complete CFW-10 series is based on tests performed on sample models. A Technical Construction File (TCF) was prepared, checked and approved by a Competent Body.

CHAPTER 4

KEYPAD (HMI) OPERATION

This chapter describes the CFW-10 operation via Human-Machine Interface (HMI), providing the following information:

General keypad description (HMI); Use of the keypad (HMI); Inverter parameters arrangement; Alteration mode parameters (programming); Description of the status indicators.

4.1 KEYPAD (HMI)

DESCRIPTION

The standard CFW-10 keypad has a LED display with 3 digits of 7 segments, 2 status LEDs and 4 keys. Figure 4.1 shows the front view of the keypad and indicates the position of the Display and the status LEDs. CFW-10 Plus version still has a potentiometer for speed setting.

Functions of the LED Display:

The Led Display shows the fault and status messages (see Quick Parameter Reference, Fault and Status), the parameter number and its value.

Functions of the LED´s “Parameter” and “Value”:

Inverter indicates the parameter number: Green Led OFF and red Led ON.

Inverter indicates the parameter content: Green Led ON and red Led OFF.

Figure 4.1 - CFW-10 keypad (HMI)

CHAPTER 4 - KEYPAD (HMI) OPERATION

The Keypad (HMI) is a simple interface that allows inverter operation/ programming. This interface has the following functions:

Indication of the inverter status and operation variables;

Fault indication and diagnostics;

Viewing and programming parameters;

Inverter operation (key ) and speed reference setting (keys and );

Potentiometer for the output frequency variation (only in the Plus version).

4.2 USE OF THE KEYPAD (HMI)

Basic Functions of the Keys:

Enables/disables the inverter via acceleration/deceleration ramp (run/ stop). Resets the inverter after a fault trip.

Selects (commutates) the display between parametyer number/value (position/content).

Increases thefrequency, theparameter number or theparameter value.

Decreases the frequency, the parameter number or the parameter value.

4.2.1 Keypad (HMI)

Operation

All functions relating to the CFW-10 operation (Start/Stop, Increment/ Decrement of the Speed Frequency) can be performed through the HMI selection. For factory default programming of the inverter, all keypad keys are enabled. Thesefunctions can be carried out through digital and analog inputs. Thus you must program the parameters related to these corresponding inputs.

NOTE!

The command key will be enabled only when:

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

See below the keypad functions description:

When pressed, motor accelerates according to acceleration ramp up to the speed (frequency) reference. The function is similar to that performed through digital input START/STOP, when it is closed (enabled) and maintained enabled. When pressed again, inverter is disabledvia ramp (motor accelerates according to acceleration ramp and stops). The function is similar to that performed through digital input START/STOP, when it is opened (disabled) and maintained disabled.

CHAPTER 4 - KEYPAD (HMI) OPERATION

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). To change the frequency reference before inverter is enabled, you must change the value of the parameter P121.

and

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.

Inverter status:

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 chapter 7).

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 routineto identify paramet er s aut omatically. This operation is controlled by P204 (refer to chapter 6).

4.2.2 Inverter Status HMI Display

NOTE!

On CFW-10 Plus version, the motor frequency setting function is made through the HMI potentiometer. However, it is possible to set the motor frequency through the keys since P221/P222 parameters were programmed.

NOTE!

Besides the fault conditions, the display also flashes when the inverter is in overload condition (refer to chapter 7).

CHAPTER 4 - KEYPAD (HMI) OPERATION

4.2.4 Parameter Viewing and Programming

All inverter settings are made through parameters. Parameters and their contents are shown on the Display through the LED´s " Parameter" and "Value". The identification is made between parameter number and its value. Example (P100):

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 changethe parameter content(s).

To allow the reprogramming of any parameter value 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.

4.2.3 Read-Only Variables

Parameters from P002 to P008 are reserved for the display of readonly variables. When the inverter is powered up, the display will indicate the value of the Parameter P002 (output frequency value).

CHAPTER 4 - KEYPAD (HMI) OPERATION

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

inverter will use the new value immediately after it has been set. Forparameters that can be changed only with stopped motor , 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 saved automatically in the volatile memory and will remain stored there until a new value is programmed.

(3)If the last programmed value in the parameter is not functionally

compatible with the other parameter values already programmed, the E24 = Programming Error - will be displayed. Example of programming error: Programming of two digital inputs (DI) with the samefunction. Refer to table 4.1 for list of programming errors that can generate an E24 Programming Error.

(4)To change any paramater value, you must set before P000 = 5.

Otherwise you can only read the parameter values, but not reprogram them. For more details, see P000 description in Chapter 6.

5.1 PRE-POW ER

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 (See Electrical Installation).

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

DANGER!

Always disconnect theAC 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.

3) Uncouple the load from the motor

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

5.2 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: - 15 % / + 10 %).

2) Power-up the AC input

Close the input circuit breaker.

3) Check if the power-up has been succesful

The keypad display will show:

While the red LED (Parameter) is ON, the green LED (Value) remains OFF. Inverter runs some self-diagnosis routines. If no problems are found, the display shows:

START-UP

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

CHAPTER 5 - START-UP

5.3 START-UP DANGER!

Even after theAC 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

3.2.6). Inverter must be already installed and powered up according to Chapter 3 and Section 5.2.

5.3.1 Start-up Operation via Keypad (HMI)

Connections according to figure 3.6.

NOTE!

The last frequency reference (speed) value 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. Wait 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 (I x R compensation) at P136. Increase/decrease the content of P136gradually 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 display occurs during deceleration, increase the

deceleration time at P101 / P103.

6.1 SYMBOLS

Please find below some symbols used in this chapter:

AIx = Analog input number x. AO = Analog output. DIx = Digital input number x. F* = Frequency reference. This is the frequency value (or alternatively,

of speed) that indicates the desired motor speed at the inverter output.

= Input frequency of the acceleration and deceleration ramp.

max

= Maximum output frequency, defined at P134.

min

= Minimum output frequency, defined at P133.

= Output frequency - frequency applied to the motor.

nom

= Rated inverter output current (rms), in Ampères (A). This value

is defined in P295.

= Inverter output current.

= Active current at inverter output, i.e., it is the component of the total motor current proportional to active electric power absorbed by the motor.

RLx = Relay output number x. U

= DC link voltage in the DC link circuit.

This section describes the main concepts related to the CFW-10 frequency inverter.

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 (I x R 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. 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/60 Hz, the minimum speed variation at no load condition and at rated load can be maintained between 18 to 36 rpm.

There is still a variation of the linear V/F control previously described: The quadratic V/F control.

DETAILED PARAMETER DESCRIPTION

CHAPTER 6

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

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 to XC1:9) (see P221, P222 and P234 to P236);

Multi-speed - 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 (DI1 and DI4) - see P221, P222, P263 and P266;

HMI Potentiometer – the reference can be changed through the HMI potentiometer (Only available on CFW-10 Plus version).

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.

6.2.2 Frequency Reference Sources

This control is suitable for applications like centrifugal pumps and fan (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.

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

6.2.3 Commands The inverter has the following commands: PWM pulse enabling/ disabling, definition of the direction of rotation and JOG. As the frequency reference, also the inverter commands can de defined in several ways. The main command sources are:

Via keypad key -key ; Via control terminals (XC1) - digital inputs.

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

Via keypad of the HMI; Start/Stop (terminals XC1 - DI(s) - see P263 to P266); General enable (terminals XC1 - DI(s) - see P263 to P266); Forward and Reverse (terminals XC1 – DI’(s) - see P263 to P266) – also defines the direction of rotation; ON/OFF (3-wire controls) (terminals XC1 - DI’(s)- see P263 and P266).

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

Digital input (DI) programmed for FWD/REV (see P263 to P266); Digital inputs programmed as FWD / REV, that defines both inverter enabling or disabling and direction of rotation (see P263 to P266); Analog input - when the referenceis via analog input and a negative offset is programmed (P236 < 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 modethe inverter can be controlled by using the keypad, (HMI) while in remote mode all controls are via terminals (XC1) - inverter reference and command definition.

This set of parameters defines the times 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 . When factory setting is used, inverter always follows the time defined in P100 and P101. If Ramp 2 should be used, where the acceleration and deceleration times follow the values programmed at P102 and P103, use a digital input. See parameters P263 to P265. Depending on the load inertia, too short acceleration times can disablethe 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.

Table 6.2 - Backup configurationof digital reference

If the digital reference backup is inactive (P120 = 0), the reference will be equal to the minimum frequency every time the inverter is enabled, according to P133. When P120 = 1, inverter saves automatically the digital reference value, (independent of the reference source, keypad, EP). This occurs always when inverter disable is present, independent of the present disabl e condit ion (r amp or gen eral), error or undervoltage. When P120 = 2, the initial reference will be given by P121,and saved always the inverter is enabled. Application example: reference via EP when inverter is disabled via digital input and decelerates EP (coming to reference 0). However at a new enable, it is desired that the inverter returns to a frequency different from the minimum frequency, which will be saved at Parameter P121.

Defines the frequency reference (speed) for the JOG function. The JOG function can be activated by using the digital inputs. The inverter must be disabled by ramp (stopped motor) to operate in the JOG function. Thus if the control source is via terminal, there must be at least one digital input programmed as start/stop enabling (otherwise E24 will be displayed), which must be OFF to enable the JOG function via digital input.

Activation of the multispeed function: To ensure that the reference source is given by the multispeed function, i.e., setting P221 = 6 for local mode or P222 = 6 for remote mode; To program one or more digital inputs to multispeed, according to table below:

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

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

If a multi-speed reference (P124 to P131) is set to 0.0 Hz and this same reference is selected, the drive will decelerate to 0.0 Hz and will remain ready (RDY) while the selection is kept. The multispeed function has some advantages for the stabibilty of the fixed preprogrammed references and the immunity against electric al noises (digital references and insulated digital inputs).

Compensates the voltage drop due to the motor stator resistance.It acts at low speeds by increasing the inverter output voltage, in order to maintain a constant torque during the V/F operation. The best setting is to program the lowest value for P136 that still permits the motor start satisfactorily. If thevalue is higher than required, an inverter overcurrent (E00 or E05) may occur due to high motor currents at low speeds.

The automatic torque boost compensates for the voltage drop in the stator resistance as a function of the active motor current. The criteria for setting P137 are the same as for the parameter P136. Setting P137 = 100 % corresponds to the maximum increment of the output voltage (30 % of P142).

The parameter P138 is used in the motor slip compensation function. This function compensates the drop of the motor speed due to load, which is a inherent characteristic relating to the operation principle of the induction motor. This speed drop is compensated by increasing the output frequency (applied to the motor) as a function of the increase of the active motor current, as shown in the block diagram and in the V/F curve below.

To set the parameter P138 adopt the following procedure:

- run the motor without load up to approximately half of the application top speed;

- measure the actual motor or equipment speed;

- apply rated load to equipment;

- increase parameter P138 until the speed reaches its no-load speed.

Define the V/F curveused 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.

NOTE! For inverter models 110-127 V; the output voltage applied to the motor is doubled the power supply voltage on the inverter input.

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 programmable 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 220 V/300 Hz and a motor for 200 V/60 Hz. Parameter P142 is also useful in appplications that require rated voltage different from the inverter supply voltage. Example: 220 V line and 200 V motor.

The DC link voltage regulation (ramp holding) avoids inverter disable due to overvoltage trips (E01) during decelerat ion of loads with high inertia or short deceleration times. It acts in order to increase the deceleration time (according to load - inertia), thus avoiding the E01 activation.

Figure 6.12 -Deceleration curve withDC Link voltage regulation

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 alternative to increase P136;

This function is used to protect the motor against overload (I x t function - E05). The motor overload current is the current level above which the inverter will consider the motor operating under overload. The higher the difference between the motor current and the overload current, the sooner the I x t function - E05 - will act.

Prevents motor stalling during an overload. If motor load increases its current will increase too.

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 3 Hz 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 conveyor s , 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).

Example of a application: centrifugal pumps, fans, multimotor drivings.

In the event of a fault trip, except for E09, E24, E31 and E41, theinverter can start an automatic reset after the time given by P206 is elapsed. If P206 2 Auto-Reset does not occur. If after Auto-Reset the same fault is repeated three times consecutively, the Auto-Reset function will be disabled. A fault is considered consecutive if it happens again within 60 seconds after theAuto-Reset. Thus if a fault occurrs four times consecutively, this fault remains indicated permanently (and inverter disabled).

It allows that the read-only parameter P002 indicates the motor speed in any 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. Always when the value of the multiplication of P208 x P005 is higher than 999, the displayed value remains at 999.

Defines the switching frequency of the IGBTs in the inveter. 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 IGBTs losses, increasingthe drive components temperature and thus reducing their useful life. The predominant frequency on the motor is twice the switching frequency setat P297. Thus, P297 = 5 kHz results in an audible motor noise corresponding to 10 kHz. This is due to the used PWM technique . The reductionof theswitching frequencyalso contributes to the reduction of instability and ressonance that may occur in certain application conditions, as wellas reduces the emission of electromagnetic energy by the inverter. Thereductionof the switching frequencies alsoreduces the leakage currents to ground. Use currents according to table below:

Parameter Unit Description / Notes

Before DC braking starts, there is a "Dead Time" (motor runs freely) requiredfor the motor demagnetization. This time is function of the motor speed at which the DC braking occurs (output frequency).

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.

In applications where the motor current is lower than therated inverter current, and where the braking torque is not enough for the braking condition, please contact WEG to optimize the settings.

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

6.3.4 Special Functions Parameters – P500 to P599

6.3.4.1 Introduction

Other application examples: level control, temperature, dosing, etc. The CFW -10 is fitted with PID regulator function that can be used for closed loop process control. This function works as a proportional, integral and derivative regulator which superimposes the normal inverter speed control.

The speed will be changed in order to maintain the process variable (the one that want to be controlled – for example: water level of a reservoir) at the desired value, set at the reference (set point).

For instance, a motor connected to a pump and driven by an inverter makes a fluid circulate into the piping. The inverter itself can make the flow control into the piping by means of the PID regulator. In this case, for example, the set point (flow) could be given by the input (HMI Potentiometer) or through P525 (digital set point) and the flow feedback signal would come to the analog AI1 input.

Other application examples: level control, temperature, dosing, etc.

6.3.4.2 Description

Figure 6.23 shows a schematic representation of PID regulator function.

The feedback signal must come in the analog input AI1.

The set point is the process variable value which desires to operate. This valueis entered as percentage, and it is defined by the following equation:

Setpoint (%) =

setpoint (UP)

x P234

full scale of used sensor (UP)

Where both set point and full scale of the used sensor are given by the process unit (i.e., °C, bar, etc.). Example: A pressure transducer (sensor) with 4 - 20 mA output and 25 bar full scale (i.e., 4 mA = 0 bar and 20 mA = 25 bar) and P234 = 200. If 10 bar is desired to control, the following set point should be entered:

Setpoint (%) =

x 200 = 80 %

The set point can be defined via:

- Keypad: digital set point, P525 parameter.

- Input (HMI potentiometer) (only available in the CFW -10 Plus): the percentage value is calculated based on P238 and P240 (see description of these parameters).

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

The P040 parameter indicates the process variable value (feedback) in the selected scale at P528, which is set according to the following equation:

P528 =

full scale of used sensor

x 100

P234

Example: Consider the previous example data (pressure sensor of 0 - 25 bar and P234 = 200). P528must be set to (25/200) x 100 = 12.5.

NOTE!

In case of none digital input has been selected for manual/automatic

function, the PID always will work on the automatic condition.

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

NOTE!

When PID (P203 = 1) function is enabled:

Program one of the digital inputs DIX (P263 to P266 = 27). In this manner, with closed DIX it operates inmanual mode(without closing the loop control – feedback) and opening the DIX the PID regulator starts to operate (closed loop control – automatic mode). If there is no digital input (DIx) selected for manual/automatic function (P263 to P266 = 27), the inverter operation always will be in automatic mode. If P221 or P222 is equal to 1, 2, 4, 5, 6 or 7 there will be an E24 indication. Set P221 and P222 equal to 0 or 3 as need. In manual mode the frequency reference is given by F* according to figure 6.1. When changed from manual to automatic, P525 = P040 is automatically set if P536 = 0 (at the moment immediately before the commutation). In this manner, if the set point is defined by P525 (P221 or P222 = 0) and changed from manual to automatic, P525 = P040 is automatically set, since P536 parameter is active (P536 = 0). In this case, the commutation from manual to automatic is smooth (there is no abrupt speed variation). The following figure 6.24 shows an application example of an inverter controlling a process in closed loop (PID regulator).

6.3.4.3 Start up Guide

Find below a start-up procedure for the PID regulator:

Initial Definitions

1) Process - To define the PID type of action that theprocess requires: direct or reverse. The control action must be direct (P527 = 0) when it is required to increase the motor speed and so also increment the process variable. Otherwise select reverse (P527 = 1).

Examples: a) Direct: Pump driven by an inverter and filling a reservoir where the

PID regulates the reservoir level. To increase the reservoir level (process variable) the flow must be increased and consequently also the motor speed must be increased.

b) Reverse: Fan driven by an inverter to cool a cooling tower, with the

PID controlling the tower temperature. When it is requiredto increase the temperature(process variable), the cooling must be decreased by reducing the motor speed.

2) Feedback (process variable measurement):

It is always via analog input AI1.

Transducer (sensor) to be used for the feedback of the control variable: it is recommended to use a full scale sensor with minimum 1.1 times higher than the largest value of the process variable that shall be controlled. Example: If a pressure control at 20 bar is desired, select a sensor with a control capacity of at least 22 bar.

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

Signal type: set P235 according to transducer signal (4-20 mA, 0-20 mA or 0-10 V).

Set P234 according to the variation range of the used feedback signal (for more details see parameters descriptions P234 to P240).

Example: suppose the following application:

- Full scale of the transducer (maximum value at the transducer output) = 25 bar (FS = 25);

- Operation range (range of interest) = 0 to 15 bar (FO = 15). Considering a safety margin of 10 %, the measuring range of the process variable must be set to: 0 to 16.5 bar. Thus: FM = 1.1 x FS = 16.5. In this manner, the P234 parameter must be set to:

P234 =

x 100 =

x 100 = 152

FM 16.5

As the operation range starts at zero, P236 = 0. Thus, a set point of 100 % represents 16.5 bar, i.e., the operation range, in percentage is: 0 to 90.9 %.

NOTE!

In most of the cases it is not necessary to set the gain and the offset (P234 = 100 and P236 = 0.0). Thus, the percentage value of the set point is equivalent to thepercentage value of the full scaleused sensor. However, if the maximum resolution of the analog input AI1 (feedback) is desired, set P234 per previous explanation.

Setting of the display indication to the process variable measuring unit (P040): set P528 according to the full scale of the used transducer (sensor) anddefined P234 (see the following description of parameter P528)

3) Reference (set point): Local/remote mode. Reference source: Set P221 or P222 according to last definition.

4) Speed Limits: Set P133 and P134 according to the application.

Start Up

1) Manual Operation (closed DI): Display indication (P040): check indication based on external measurement and on the feedback signal (transducer) at AI1. Vary the frequency reference (F*) until the desired value of the process variable is reached. Only then switchto the automatic mode (inverter willset automatically P525 = P040), if P536 equal to zero.

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

2) Automatic Operation: open the DI and make the dynamic setting of the PID regulator, i.e., set the proportional gain (P520), integral gain (P521) and differential gain (P522).

NOTE!

The inverter setting must be correct in order to obtain a good performance of the PID regulator. Ensure the following settings:

Torque boosts (P136 and P137) and slip compensation (P138) in the V/F mode control (P202 = 0 or 1); Acceleration and deceleration ramps (P100 to P103); Current limitation (P169).

Inverter parameterization:

P203 = 1 P238 = 100 P221 = 0 or 3 P240 = 0 P222 = 0 or 3 P265 = 27 P229 = 1 P525 = 0 P234 = 100 P526 = 0.1 P235 = 1 P527 = 0 P236 = 000 P528 = 25

DIAGNOSTICSAND TROUBLESHOOTING

This chapter assists the user to identify and correct possible faults that can occur during the CFW-10 operation. Also instructions about required periodical inspections and cleaning procedures are also provided.

When a fault is detected, the inverter is disabled and the fault code is displayed on the readout in EXX form, where XX is the actual fault code.

To restart the inverter after a fault has occurred, the inverter must be reset. The reset can be made as follows:

disconnect and reapply the AC power (power-on reset); press key (manual reset); automatic reset through P206 (auto-reset); via digital input: DI1 to DI4 (P263 to P266 = 21).

The table below defines each fault code, explains how to reset the fault and shows the possible causes for each fault code.
