2.2 ABOUT THE CFW700

The CFW700 frequency inverter is a high performance product designed for speed and torque
control of threephase induction motors. The main characteristic of this product is the “Vectrue”
technology, which has the following advantages:

 Scalar control (V/f), VVW or vector control programmable in the same product.

 The vector control may be programmed as “sensorless” (which means standard motors

without using encoders) or as “vector control” with the use of an encoder.

 The “sensorless” control allows high torque and fast response, even in very low speeds or at

the starting.

 The “vector with encoder” control allows high speed precision for the whole speed range

(even with a standstill motor).

CFW700 | 3

General Instructions

 “Optimal Braking” function for the vector control, allowing the controlled braking of the motor

and avoiding external braking resistor for some applications.

English

 “Self-Tuning” feature for vector control. It allows the automatic adjustment of the regulators

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

The main components of the CFW700 can be viewed in Figure A.1 on page 201.

3.1 MECHANICAL INSTALLATION

English

3.1.1 Installation Environment

Avoid installing the inverter in an area with:

 Direct exposure to sunlight, rain, high humidity, or sea-air.

 Inflammable or corrosive gases or liquids.

 Excessive vibration.

 Dust, metallic particles, and oil mist.

Environment conditions for the operation of the inverter:

 Inverter surrounding temperature: from -10 ºC up to Ta according to the Table B.4 on page 216.

 For temperatures around the inverter greater than Ta and smaller than 60 °C (frame sizes

A, B, C and D), 40 °C (models with degree of protection IP55) and 55 °C (frame size E), it is
necessary to apply current reduction of 2 % for every degree Celsius (or 1.11 % each °F) up
to Ta.

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

 Altitude: up to 1000 m (3,300 ft) - standard conditions (no derating required).

 From 1000 m to 4000 m (3,300 ft to 13,200 ft) - current derating of 1 % each 100 m (or 0.3 %

each 100 ft) above 1000 m (3,300 ft) altitude.

 From 2000 m to 4000 m (6,600 ft to 13,200 ft) above sea level - maximum voltage reduction

(240 V for 200...240 V models, 230 V for 220...230 V models, 480 V for 380...480 V models
and 600 V for 500...600 V models) of 1.1 % for each 100 m (330 ft) above 2000 m (6,600 ft).

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

Condensation shall not originate conduction through the accumulated residues.

3.1. 2 Mounting Considerations

External dimensions, fixing holes position and net weight of the inverter are presented at Figure

B.2 on page 232 and Figure B.3 on page 234. Please refer to Figure B.4 on page 235 to
Figure B.11 on page 242 for more details of each inverter size.

Install the inverter upright on a flat surface. First place the screws on the surface where the
drive is going to be installed, install the drive and then tighten the screws.

Frame size E inverters with N1 option (CFW700E...N1...):

 After fixing the inverter, install the upper Nema 1 kit on the inverter using the two M8 screws

provided with the product.

10 | CFW700

Installation and Connection

Let the minimum clearances specified in Figure B.3 on page 234 in order to allow air circulation
for cooling. It is possible to assembly frame sizes A, B and C inverters with IP20 protection
degree (CFW700… 20…) side by side without lateral spacing, i.e., with the D distance presented
in Figure B.3 on page 234 equal to zero.

Do not install heat sensitive components right above the inverter.

ATTENTION!

 When arranging two or more inverters vertically, respect the minimum

clearance A + B (Figure B.3 on page 234) and provide an air deflecting
plate so that the heat rising up from the bottom inverter does not affect the
top inverter.

 Provide conduit for physical separation of the signal, control, and power

conductors (refer to section 3.2 ELECTRICAL INSTALLATION on page 11).

Please refer to Figure B.3 on page 234 for surface and flange mounting data. The inverter
dissipated power at rated condition for surface and flange mounting is presented in Table B.4

on page 216. Remove the drive mounting brackets for flange mounting. The protection degree

of the inverter outside the panel is IP55 for flange mounting. It is necessary to provide proper
seal for the opening where the inverter is installed to ensure the protection degree of the panel.
Example: sealing with silicone.

Please refer to Figure A.4 on page 204 for more details on the access to the control and
power terminals.

3.2.2 Power / Grounding Wiring and Fuses

ATTENTION!

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

Refer to Table B.1 on page 212, Table B.2 on page 213 and Table B.3 on page 214 for the
recommended wiring and fuses and Table B.5 on page 223 for the specifications of the power
terminals.

NOTE!

The gauges values presented in Table B.1 on page 212, Table B.2 on page 213
and Table B.3 on page 214 are for reference only. Installation conditions and the
maximum permitted voltage drop shall be considered for the proper wiring sizing.

Input fuses

 The fuses to be used at the input must be HS (High-Speed) type with I

value indicated in the Table B.1 on page 212, Table B.2 on page 213 and Table B.3 on

page 214 (consider extinction current value in cold situation (it is not the fusion value)), to

protect the inverter diode rectifiers and input wiring.

 In order to meet UL requirements, use class J fuses at the inverter supply with a current not

higher than the values presented in Table B.1 on page 212, Table B.2 on page 213 and

Table B.3 on page 214.

Installation and Connection

ATTENTION!

In order to be able to use the CFW700 with built-in C3 RFI filter (frame sizes A, B, C

English

and D with optional RFI f ilter and all frame size E inverter models – CFW700…C3…)
in IT networks (neutral conductor not grounded or grounded via a high ohmic value
resistor) or in corner-grounded delta systems, it is necessary to remove some RFI
filter components (capacitor for frame sizes A, B, C and D and capacitor and the
MOV for frame size E) connected to the ground by removing the screws indicated
in Figure A.8 on page 208 for inverter frame sizes A, B, C and D and changing the
position of the J1 jumper on the PRT1 board from (XE1) to “NC” (XIT), according
to the Figure A.8 on page 208 for inverter frame size E.

AC power supply considerations

 Suitable for use on a circuit capable of delivering not more than 100.000 A

Ampères at 240 V, 480 V or 600 V maximum, when protected by Class J fuses (for 240 V

symmetrical

rms

and 480 V models) or special purpose fuses (for 600 V).

3.2.3.2 Dynamic Braking (standard built-in for frame sizes A, B, C and D and optional built-in for frame size E - CFW700...DB...)

Refer to Table B.1 on page 212, Table B.2 on page 213 and Table B.3 on page 214 for
the following dynamic braking specifications: maximum current, resistance, RMS current (*)
and cable gauges.

The power rating of the dynamic braking resistor is a function of the deceleration time, the load
inertia and the resistant torque.

Dynamic braking installing procedure:

 Install the braking resistor between the power terminals DC+ and BR.

 Use twisted cable for the connection. Separate these cables from the signal and control

cables.

 Size the cables according to the application, respecting the maximum and effective currents.

 If the braking resistor is installed inside the inverter cabinet, consider its additional dissipated

energy when sizing the cabinet ventilation.

 The thermal protection of the dynamic brak ing resistor must be provided ex ternally using a thermal

relay in series with the resistor and/or a thermostat in contact with the resistor frame, connected
so as to switch the input power supply of the inverter, as shown in Figure 3.3 on page 17.

 Set P0151 and P0185 to their maximum values (400 V or 800 V) when using dynamic braking.

 The DC link voltage actuation level of the dynamic braking is set by parameter P0153 (Dynamic

Braking Level).

ATTENTION!

 The inverter has an electronic motor overload protection that shall be adjusted

according to the driven motor. When several motors are connected to the
same inverter, install individual overload relays for each motor.

 The motor overload protection available for the CFW700 is in accordance

with UL508C as per the following information:

- "Trip" current equal to 1.25 times the motor rated current (P0401) adjusted
in the "Oriented Start-up" menu.

- The maximum value of P0398 (Motor Service Factor) is 1.15.

- Parameters P0156, P0157 and P0158 (Overload Current at 100 %,
50 % and 5 % of the rated speed, respectively) are automatically adjusted
when the parameters P0401 (Motor Rated Current) and/or P0406 (Motor
Ventilation) are changed on the “Oriented Start-up” menu. If the parameters
P0156, P0157 and P0158 are set manually, the maximum allowed value
is 1.05 x P0401.

Installation and Connection

ATTENTION!

If a disconnect switch or a contactor is installed between the inverter and the

English

motor, never operate them with a spinning motor or with voltage at the inverter
output.

The characteristics of the cable used for the inverter and motor interconnection, as well as
the physical location are extremely important to avoid electromagnetic interference in other
equipment and to not affect the life cycle of motor windings and motor bearings controlled by
inverters.

Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.),
according to item 3.2.6 Cable Distances on page 23.

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

When using shielded cables for connecting the motor:

 Follow the recommendations of IEC60034-25.

 Use low impedance connection to high frequencies to connect the cable shield to ground.

Using parts supplied with the drive. See item below.

 For inverter frame sizes A, B and C there is an accessory called “Shielding kit for power

cables PCSx-01” (see section 7.2 ACCESSORIES on page 58), which can be mounted at
the bottom of the cabinet – the Figure 3.4 on page 18 shows an example. The shielding
kit for power cables PCSx-01 goes along with inverters with optional internal C3 RFI filter
(CFW700...C3...). The grounding for the motor cable shield on inverter frame sizes D and E is
already provided in the standard inverter cabinet. This is also provided on the “Nema1 Kits
(KN1x-01)” of the inverter frame sizes A, B and C.

 For frame sizes B and C with degree of protection IP55, the accessory "PCSC-03 power

cable shield kit" is available, and for frame size D and E with degree of IP55 use the standard
accessories for shielding. The PCSC-03 shield kit comes with the inverter as optional item N12.

4.2 APPLICATIONS

The CFW700 has some features that allow better matching the inverter commands to the
application. These features were grouped into a set of applications and can be as simple as the
forward and reverse command, or more elaborated such as a PID controller.The applications
were implemented using the SoftPLC function, in other words, ladder programming applicative
built-in to the CFW700 inverter. It allows the user that has the WLP and the built-in implemented
applicative to change it and use it as an user applicative.

Parameter P1003 allows selecting an application and uploading it to the CFW700. The CFW700
has following applications built-in:

 PID Regulator.

English

 Electronic Potentiometer (E.P.).

 Multispeed.

 3-Wire Start/Stop.

 Forward/Reverse Run.

4.2.1 PID Regulator Application

The CFW700 has the PID REGULATOR application that can be used to control a closed loop
process. This application sets proportional, integral and derivative regulator superimposed to
the regular speed control of the CFW700 inverter.

The CFW700 will compare the setpoint with the process variable and control the motor speed
trying to eliminate any error and keeping the process variable equal to the setpoint. The setting
of the P, I and D gains determines how fast the inverter will respond to eliminate this error.

Application examples:

 Flow control or pressure in a pipe system.

 Temperature of a furnace or oven.

 Dosing of chemicals in tanks.

CFW700 | 29

Keypad (HMI) and Basic Programming

The following example defines the terms used by the PID controller.

A pump used in a water pumping system where is necessary to control the pressure of the
pipe. A pressure transducer is installed in the pipe and supplies an analog feedback signal

English

to the CFW700, which is proportional to the water pressure. This signal is called the process
variable, and can be visualized at the parameter P1012. A setpoint is programmed in the
CFW700 via keypad (P1025), through an analog input (such as a 0-10 V or 4-20 mA signal) or
via communication network. The setpoint is the desired water pressure value that the pump is
supposed to produce, regardless of the consumption variations at the pump output at any time.

It is necessary to set the parameter P0221 or P0222 to 7 = SoftPLC for the operation of the
PID Regulator application.

Definitions:

 The Function 1 of the Application at parameters P0231 or P0236 represents the value of the

PID Setpoint.

 The Function 2 of the Application at parameters P0231 or P0236 represents the value of the

PID Feedback.

 The Function 1 of the Application at parameters P0251 or P0254 represents the value of the

PID Setpoint.

 The Function 2 of the Application at parameters P0251 or P0254 represents the value of the

PID Feedback.

 The Function 1 of the Application at parameters P0263 or P0270 represents the value of the

Manual/Auto command.

 The Function 1 of the Application at parameters P0275 to P0279 represents the VP>VPx

logical condition.

 The Function 2 of the Application at parameters P0275 to P0279 represents the VP<VPy

logical condition.

The PID setpoint can receive an analog input signal (AI1 or AI2). It is necessary to set P1016
to 1 = AIx and select which analog input will be used. The analog inputs are set at P0231 (AI1)
or P0236 (AI2) and it is necessary to program it to 5 = Function 1 of the Application in order to
enable the analog inputs for the operation. The following alarm message will be displayed in
case it is not properly done: “A770: Set AI1 or AI2 for Function 1 of the Application”.

The PID setpoint value can be presented via analog output AO1 or AO2. It is necessary to set
P0251 (AO1) or P0254 (AO2) to 17 = Function 1 of the Application. The full scale value of the
variable is 100.0 % and corresponds to 10 V or 20 mA.

The PID feedback can receive an analog input signal (AI1 or AI2). It is necessary to set P0231
(AI1) or P0236 (AI2) to 6 = Function 2 of the Application in order to enable the analog inputs for
the operation. The following alarm message will be displayed in case it is not properly done:
“A772: Set AI1 or AI2 for Function 2 of the Application”.

In case the analog inputs (AI1 and AI2) are programmed with the same function, PID Setpoint
or Feedback, the following alarm message will be displayed and the application will not be
enabled: “A774: AI1 and AI2 were set for the same function”.

30 | CFW700

Keypad (HMI) and Basic Programming

The value of the PID feedback can be presented via analog output AO1 or AO2. It is necessary
to set P0251 (AO1) or P0254 (AO2) to 18 = Function 2 of the Application. The full scale value of
the variable is 100.0 % and corresponds to 10 V or 20 mA.

The Manual/Auto control is done by a digital input (DI1 to DI8). It is necessary to set one of the
DI parameters (P0263 to P0270) to 20 = Function 1 of the Application. If more than one digital
input is set for this function, the logic operation will consider only the command of the high
priority level digital input, where: DI1>DI2>DI3>DI4>DI5>DI6>DI7> DI8. If any of the digital inputs
is set, the PID controller will work only in automatic (Auto) mode.

The Manual/Auto input is active when it is in 24 V indicating automatic control and it is inactive
in 0 V indicating manual operation.

The digital outputs (DO1 to DO5) can be programmed to trigger comparison logics with the
process variable (PV). In order to do that, it is necessary to set one of the DO’s parameters
(P0275 to P0279) to 34 = Function 1 of the Application (VP>VPx) or 35 = Function 2 of the
Application (VP<VPy).

4.2.1.1 Academic PID

The PID controller implemented in CFW700 is the academic type. The equations that characterize
the Academic PID, which is the base of this function algorithm, are presented next.The transfer
function in the Academic PID regulator frequency dominion is:

y(s) = Kp x e(s) x [1 + 1 + sTd ]

By replacing the integrator by a sum and the derivative by the incremental quotient, one gets
an approximation for the discrete transfer equation (recursive) presented next:

y(k) = y(k-1) + Kp[(1 + Ki.Ta + Kd/Ta).e(k) – (Kd/Ta).e(k-1)]

Being:

y(k): current PID output, can vary from 0.0 to 100.0 %;
y(k-1): PID previous output;
Kp (Proportional gain): Kp = P1020;
Ki (Integral gain): Ki = P1021 x 100 = [1/Ti x 100];
Kd (Differential gain): Kd = P1022 x 100 = [Td x 100];
Ta = 0.05sec (PID regulator sampling time);
e(k): current error [SP*(k) – X(k)];
e(k-1): previous error [SP*(k-1) – X(k-1)];
SP*: reference, can vary from 0.0 to 100.0 %;
X: process variable (or feedback), read through one of the analog inputs (AIx), can vary from

0.0 to 100.0 %.

4.2.2 Electronic Potentiometer (EP) Application

The CFW700 has the Electronic Potentiometer (E.P.) function that allows the speed reference to
be adjusted via two digital inputs, one for accelerating and another for decelerating the motor.

With the inverter enabled and the DIx digital input set to “Function 1 of the Application
(Accelerate)” activated, the motor is accelerated according to the programmed acceleration
ramp up to the maximum speed. If only the DIx digital input set to “Function 2 of the Application
(Decelerate)” is active and the inverter is enabled, the motor speed is decreased according to
the programmed deceleration ramp up to minimum speed. If both inputs are active, the motor
will decelerate for safety reasons. With the inverter disabled, DIx digital inputs are ignored unless
both are active, which the speed reference is set to 0 rpm. The following figure illustrates this
condition.

the values defined at parameters P1011 to P1018 through the logical combination of digital
inputs DI4, DI5 and DI6, having the limit of eight pre-programmed speed references. It brings
advantages such as stability of the pre-programmed fixed references and electrical noise
immunity (isolated digital inputs DIx).

The speed reference selection is done by the logical combination of the digital inputs DI4, DI5
and DI6. Their respective parameters (P0266, P0267 and P0268) must be set to “Function 1
of the Application (Multispeed)”. If any digital input us set to “Function 1 of the Application”,

 The Function 1 of the Application at parameters P0263 to P0270 represents the Start

command.

 The Function 2 of the Application at parameters P0263 to P0270 represents the Stop

command.

The Start command is done by one of the digital inputs (DI1 to DI8). It is necessary to set one
of the DI’s parameters (P0263 to P0270) to 20 = Function 1 of the Application. If more than
one digital input is set for this function, the logic operation will consider only the command of
the high priority level digital input, where: DI1>DI2>DI3>DI4>DI5>DI6>DI7>DI8. If any digital
inputs is set, the following alarm message will be displayed: “A750: Set a DI for Function 1 of
the Application (Start)” and the operation of the application will not be enabled.

Keypad (HMI) and Basic Programming

The Stop command is also done by one of digital inputs (DI1 to DI8). However, it is necessary
to set one the DI’s parameters (P0263 to P0270) to 21 = Function 2 of the Application. If more
than one digital input is set for this function, the logic operation will consider only the command
of the high priority level digital input, where: DI1>DI2>DI3>DI4>DI5>DI6>DI7>DI8. If any digital
inputs is set, the following alarm message will be displayed: “A752: Set a DI for Function 2 of
the Application (Stop)” and the operation of the application will not be enabled.

Both Start and Stop inputs are active when 24 V is applied and inactive when 0 V is applied.

With the inverter enabled in local or remote mode, with no fault, without undervoltage, no A750
and A752 alarm, the “General Enable” command is performed in the inverter. In case some
digital input is set to “General Enable” function, the inverter will effectively be enabled when the
two command sources are active.

4.2.5 Forward/Reverse Run Application

The CFW700 has the Forward/Reverse Run application that allows the combination of two
inverter commands (Forward/Reverse and Start/Stop) in a single digital input.

This way, the digital input (DIx) programmed to “Function 1 of the Application (Forward)” combines
the forward rotation with the start/stop command and the input (DIx) programmed to “Function
2 of the Application (Reverse)” combines the reverse rotation with the start/stop command. The

It is necessary to set the parameter P0223 to 9 = SoftPLC (CW) or 10 = SoftPLC (CCW) together
with P0224 to 4 = SoftPLC, or else, it is necessary to set P0226 to 9 = SoftPLC (CW) or 10 =
SoftPLC (CCW) together with P0227 to 4 = SoftPLC for the operation of the Forward/Reverse Run
application. The following alarm message will be displayed in case the Local FWD/REV selection

English

is not set (P0223): “A760: Set Local FWD/REV to SoftPLC” and the operation of the application
will not be enabled if the Local Run/Stop selection (P0224) has been set to SoftPLC. The same
applies to the Remote FWD/REV (P0226), i.e., the following alarm message will be displayed:
“A762: Set Remote FWD/REV to SoftPLC” and the operation of the application will not be enabled
if the Remote Run/Stop selection (P0227) has been set to SoftPLC.

Definitions:

 The Function 1 of the Application at parameters P0263 to P0270 represents the Forward

command.

 The Function 2 of the Application at parameters P0263 to P0270 represents the Reverse

command.

The Forward command is done by one of the digital inputs (DI1 to DI8). It is necessary to set
one of the DI’s parameters (P0263 to P0270) to 20 = Function 1 of the Application. If more than
one digital input is set for this function, the logic operation will consider only the command of
the high priority level digital input, where: DI1>DI2>DI3>DI4>DI5>DI6>DI7>DI8. If any digital
inputs is set, the following alarm message will be displayed: “A750: Set a DI for Function 1 of
the Application (Forward)” and the operation of the application will not be enabled. It is defined
that the forward command rotation will always be “clockwise”.

The Reverse command is also done by one of digital inputs (DI1 to DI8). However, it is necessary
to set one the DI’s parameters (P0263 to P0270) to 21 = Function 2 of the Application. If more
than one digital input is set for this function, the logic operation will consider only the command
of the high priority level digital input, where: DI1>DI2>DI3>DI4>DI5>DI6>DI7>DI8. If any digital
inputs is set, the following alarm message will be displayed: “A752: Set a DI for Function 2 of
the Application (Reverse)” and the operation of the application will not be enabled. It is defined
that the forward command rotation will always be “counterclockwise”.

Both Forward and Reverse inputs are active when 24 V is applied and inactive when 0 V is applied.

With the inverter enabled in local or remote mode, with no fault, without undervoltage, no A750,
A752, A760 and A762 alarms, the “General Enable” command is performed in the inverter. In
case some digital input is set to “General Enable” function, the inverter will effectively be enabled
when the two command sources are active.

With the forward digital input active and the reverse digital input inactive, the forward and
start commands are performed. If the reverse digital input is active, nothing is changed in the
operation of the inverter. When both commands are inactive, the start command is removed
and the motor will be decelerated to 0 rpm. However, when the reverse digital input is active
and the forward digital input is inactive, the reverse and start command are performed. If the
forward digital input is active, nothing is changed in the operation of the inverter. When both
commands are inactive, the start command is removed and the inverter decelerates to 0
rpm. In case both forward and reverse digital inputs are active at the same time, the forward
command will be generated.

Inverter with Nema1 enclosure. Refer to Figure B.2 on page 232. These inverters have the
KN1X-02 kit (refer to section 7.2 ACCESSORIES on page 58).

English

7.1.4 IP55 Protection Degree (only for frame sizes B and C) - CFW700...N12...

Inverter with IP55 enclosure. Refer to Figure A.10 on page 210. These inverters have the
PCSC-03 kit (refer to section 7.2 ACCESSORIES on page 58).

7.1. 5 IP21 Protection Degree (only for frame sizes A, B and C) - CFW700...21...

Inverter with IP21 enclosure. Refer to Figure A.9 on page 209. These inverters have the
KIP21X-01 kit (refer to section 7.2 ACCESSORIES on page 58).

7.1.6 STO Function - CFW700...Y1...

The STO function complies with the requirements of category 3 (PL d) according to EN ISO
13849-1, SIL CL 2 according to IEC 61800-5-2 / IEC 62061 / IEC 61508 and can be used in
applications up to category 3 (PL d) according to EN ISO 13849-1 and SIL 2 according to IEC
62061 / IEC 61508. Refer to the guide or the CD ROM supplied with the product for more
information.

NOTE!

It is not possible to assemble the top cover on inverters of mechanics A that
have optional safety stop. Thus, it is not possible to raise the protection level
of these inverters to IP21 or Nema1.

CFW700 | 57

Option Kits and Accessories

7.1.7 24 Vdc External Control Power Supply - CFW700...W1...

The use of this option kit is recommended with communication networks (Profibus, DeviceNet,

English

etc.), since the control circuit and the network communication interface are kept active (with
power supply and responding to the network communication commands) even in the event of
main power supply interruption.

Inverters with this option have a built-in DC/DC converter with a 24 Vdc input that provides
adequate outputs for the control circuit. Therefore, the control circuit power supply will be
redundant, i.e., it can be provided either by a 24 Vdc external power supply (connection as
shown in Figure 7.1 on page 58 a) or b)) or by the standard internal switched mode power
supply of the inverter.

Observe that the inverters with the external 24 Vdc power supply option use terminals XC1:34
and 36 or XC1:15 and 16 as the input for the external power supply and no longer as the output
like in the standard inverter (Figure 7.1 on page 58).

In case of interruption of the external 24 Vdc power supply, the digital inputs/outputs and analog
outputs will no longer be fed, even if the mains power is on. Therefore, it is recommended to keep
the 24 Vdc power supply always connected to the terminals XC1:34 and 36 or XC1:15 and 16.

2.2 SOBRE EL CFW700

El convertidor de frecuencia CFW700 es un producto de alto desempeño que permite el control
de velocidad y del torque (par) de motores de inducción trifásicos. La característica central de
este producto es la tecnologia “Vectrue”, la cual presenta las siguientes ventajas:

 Control escalar (V/f), VV W o control vectorial programables en el mismo producto.

 El control vectorial puede ser programado como “sensorles” (lo que significa motores

padrones, sin necesidad de encoder) o como control vectorial con encoder en el motor.

 El control vectorial “sensorles” permite alto torque (par) y rapidez en la respuesta, mismo en

velocidades muy bajas o en el arranque.

CFW700 | 71

Informaciones Generales

 El control vectorial con encoder posibilita alto grado de exactitud en el accionamiento, para

todo el rango de velocidad (hasta con el motor parado).

 Función “Frenado Optimo” para el control vectorial, permitiendo el frenado controlado del

motor, eliminando en algunas aplicaciones la resistencia de frenado adicional.

 Función “Autoajuste” para el control vectorial, permitiendo el ajuste automático de los

reguladores y parámetros de control, a partir de la identificación (también automática) de los
parámetros del motor y de la carga utilizada.

Los principales componentes del CFW700 pueden ser verificados en la Figura A.1 en la página 201.

Instalación y Conexión

¡ATENCIÓN!

Si una llave aisladora o contactor fuera inserido en la alimentación del motor
nunca operarlos con el motor girando o con tensión en la salida del convertidor
de frecuencia.

Las características del cable utilizado para la conexión del convertidor de frecuencia al
motor, bien como la suya interconexión y ubicación física, son de extrema importancia para
se evitar la interferencia electromagnética en otros dispositivos, además de afectar la vida
útil del aislamiento de las bobinas y de los rodamientos de los motores accionados por los
convertidores de frecuencia.

Mantenga los cables del motor separado de los demás cables (cables de señal, cables de
sensores, cables de comando, etc.), conforme ítem 3.2.6 Distancia para Separación de Cables

en la página 92.

Conecte un cuarto cable entre el punto de tierra del motor y el punto de tierra del convertidor.

Cuando fuera utilizado cable blindado para conexión del motor:

 Seguir recomendaciones de la norma IEC60034-25.

 Utilizar conexión de baja impedancia para altas frecuencias para conectar el blindaje del cable

al punto de tierra. Utilizar piezas suministradas con el convertidor. Consulte el próximo ítem.

Español

 Para los tamaños A, B y C existe un accesorio chamado “Kit para blindaje de los cables de

potencia PCSx-01” (consulte sección 7.2 ACCESORIOS en la página 127), el cual puede
montarse en la parte inferior del gabinete – la Figura 3.4 en la página 86 muestra un ejemplo.
El kit de blindaje de los cables de potencia PCSx-01 acompaña los convertidores con la opción
de filtro RFI C3 interno (CFW700...C3...). En el caso de los tamaños D y E la puesta a tierra
del blindaje del cable del motor ya está prevista en el gabinete estándar del convertidor. Esto
también está previsto en los accesorios “Kits Nema1 (KN1x-01)” de los tamaños A, B y C.

 Para los tamaños B y C con grado de protección IP55 existe un accesorio llamado “kit de

blindaje para cables de potencia PCSC-03, y de tamaños D y E, con grado de protección
IP55 utilizar los accesorios estándar para la protección”. El kit de blindaje PCSC-03 acompaña
al convertidor con opcional N12.

Instalación y Conexión

3.2.4 Conexiones de Puesta a Tierra

¡PELIGRO!

 El convertidor de frecuencia debe ser obligatoriamente puesto a una tierra

de protección (PE).

 Utilizar cableado de puesta a tierra con calibre mínimo, igual al indicado en la

Tabla B.1 en la página 212, Tabla B.2 en la página 213 y Tabla B.3 en la
página 214.

 Conecte los puntos de puesta a tierra del convertidor a una barra de puesta

a tierra específica, o al punto de tierra específica o todavía al punto de tierra
general (resistencia ≤ 10 Ω).

 El conductor neutro de la red que alimenta el convertidor de frecuencia debe

ser aislado del sistema de puesta a tierra, sin embargo el mismo no debe
ser utilizado para hacer la puesta a tierra del convertidor.

 Para compatibilidad con la norma IEC61800-5-1 utilice como mínimo un

cable de cobre de 10 mm2 o 2 cables con el mismo calibre del cable de
puesta a tierra especificado en la Tabla B.1 en la página 212, Tabla B.2 en

la página 213 y Tabla B.3 en la página 214 para conexión del convertidor

al tierra de protección, ya que la corriente de fuga es mayor que 3,5 mA CA.

3.2.5 Conexiones de Control

Las conexiones de control (entradas/salidas analógicas y entradas/salidas digitales), deben
ser hechas en el conector XC1 de la Tarjeta Electrónica de Control CC700. Las funciones y las

A través de la HMI es posible el comando del convertidor de frecuencia, la visualización y el ajuste
de todos los parámetros. La HMI presenta dos modos de operación: monitoreo y parametrización.
Las funciones de las teclas y de los campos activos del display de la HMI varian de acuerdo con
el modo de operación. El modo de parametrización es constituído de tres niveles

- Cuando en el modo monitoreo:
presione la tecla para aumentar la
velocidad.

- Cuando en el modo parametrización,
nivel 1: presione esta tecla para ir al
grupo anterior.

- Cuando en el modo parametrización,
nivel 2: presione esta tecla para ir al
