2 GENERAL INFORMATION
2.1 ABOUT THE MANUAL
General Information
This manual contains information for the proper installation and operation of the inverter,
commissioning, main technical features and how to identify the most usual problems of the
different models of inverters of the CFW300 line.
ATTENTION!
The operation of this equipment requires detailed installation and operation
instructions provided in the quick installation guide, user's manual, programming
manual and communication manuals. The guides are provided in print with their
respective accessory, or can be obtained at WEG website - www.weg.net. A
printed copy of the files can be requested at your local WEG dealer.
NOTE!
It is not the intention of this manual to present all the possibilities for the application
of the CFW300, as well as WEG cannot take any liability for the use of the CFW300
which is not based on this manual.
Part of the figures and tables are available in the annexes, which are divided into APPENDIX
A - FIGURES on page 110 for figures and APPENDIX B - TECHNICAL SPECIFICATIONS on
page 113 for technical specifications.
For further information, refer to the programming manual.
2.2 ABOUT THE CFW300
The CFW300 frequency inverter is a high-performance product which allows speed and torque
control of three-phase induction motors. This product provides the user with the options of
vector (VVW) or scalar (V/f) control, both programmable according to the application.
English
In the vector mode (V VW ), the operation is optimized for the motor in use, obtaining a better
performance in terms of speed regulation.
The scalar mode (V/f) is recommended for simpler applications, such as the activation of most
pumps and fans. In such cases it is possible to reduce the losses in the motor and the inverter
using the "V/f Quadratic", which results in energy savings. The V/f mode is used when more
than a motor is activated by an inverter simultaneously (multimotor applications).
The frequency inverter CFW300 also has functions of PLC (Programmable Logic Controller)
by means of the SoftPLC (integrated) feature. For further details regarding the programming of
those functions, refer to the SoftPLC user's manual of the CFW300.
The main components of the CFW300 can be viewed in the blocks diagrams of Figure 2.1 on
page 4, for frame size A 220 V, Figure 2.2 on page 5 for frame size A 110 V and Figure
2.3 on page 6 for frame size B 220 V.

Installation and Connection
3.2.3.1 Input Connections
English
DANGER!
Provide a disconnect device for the inverter power supply. This device must cut
off the power supply whenever necessary (during maintenance for instance).
ATTENTION!
The power supply that feeds the inverter must have a grounded neutral.
NOTE!
The input power supply voltage must be compatible with the inverter rated
voltage.
Power factor correction capacitors are not needed at the input (L/L1, N/L2,
L3) and must not be installed at the output (U, V, W).
Power supply capacity
Suitable for use in circuits capable of delivering not more than 30.000 A
/ 240 V).
In case the CFW300 is installed in power supplies with current capacity over 30.000 A
symmetrical at (127
rms
it is necessary to use proper protection circuits for those power supplies, such as fuses or
circuit breakers.
3.2.3.2 Power Supply Reactance
In a general way, the inverters of the CFW300 line can be installed directly in the power supply,
without reactance in the supply. However, check the following:
,
rms
In order to prevent damages to the inverter and assure the expected useful life, you must
have a minimum impedance that provides a line voltage drop of 1 %. If the line impedance
(due to the transformers and cabling) is below the values listed in this table, we recommend
the use of a line reactance.
For the calculation of the line reactance necessary to obtain the desired percentage voltage
drop, use:

Seeing that: tbr corresponds to the sum of the braking actuation times during the most severe
cycle of five minutes.
The power of the brake resistor must be calculated considering the deceleration time, the inertia
of the load and of the resistive torque.
Procedure to use the dynamic braking:
Connect the brake resistor between the power terminals +BR and BR.
Use a twisted cable for the connection. Separate these cables from the signal and control
wiring.
Dimension the cables according to the application, observing the maximum and effective
currents.
CFW300 | 15
Installation and Connection
If the brake resistor is mounted within the cabinet of the inverter, consider its energy when
dimensioning the ventilation of the cabinet.
English
DANGER!
The internal braking circuit and the resistor may be damaged if the latter is not
properly dimensioned and/or if the voltage of the input power supply exceeds the
maximum value permitted. In order to avoid the destruction of the resistor or risk
of fire, the only guaranteed method is the inclusion of a thermal relay in series with
the resistor and/or a thermostat in contact with its housing, connected in such
a way to disconnect the input power supply of the inverter in case of overload,
as shown in Figure 3.2 on page 15.
Set P151 at maximum value when using dynamic braking.
The voltage level on the DC Link for activation of the dynamic braking is defined by the
parameter P153 (level of the dynamic braking).
Refer to the CFW300 programming manual.
3.2.3.4 Output Connections
ATTENTION!
The inverter has an electronic motor overload protection that must 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 in the CFW300 is in accordance with
the UL508C standard. Note the following information:
1. Trip current equal to 1.2 times the motor rated current (P401).
ATTENTION!
If a disconnect switch or a contactor is installed at the power supply between the
inverter and the motor, never operate it with the motor spinning or with voltage
at the inverter output.
The characteristics of the cable used to connect the motor to the inverter, as well as its
interconnection and routing, are extremely important to avoid electromagnetic interference in
other equipment and not to affect the life cycle of windings and bearings of the controlled motors.
Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.),
according to Item 3.2.6 Cable Separation Distance on page 18.
When using shielded cables to install the motor:
Follow the recommendations of IEC60034-25.
Use the low impedance connection for high frequencies to connect the cable shield to the
grounding.
16 | CFW300
Installation and Connection
3.2.4 Grounding Connections
DANGER!
The inverter must be connected to a protective ground (PE).
Use a minimum wire gauge for ground connection equal to the indicated in
Table B1 on page 113.
Connect the inverter grounding connections to a ground bus bar, to a single
ground point or to a common grounding point (impedance ≤ 10 Ω).
The neuter conductor of the line that feeds the inverter must be solidly
grounded; however, this conductor must not be used to ground the inverter.
Do not share the grounding wiring with other equipment that operate with high

4.3 OPERATING MODES OF THE HMI
When energizing the inverter, the initial state of the keypad remains in the start-up mode as
long as there is no fault, alarm, undervoltage or any key is pressed.
The setting mode is composed of two levels: level 1 allows the navigation through the
parameters. And level 2 allows the edition of the parameter selected at level 1. At the end of
this level the modified value is saved when the key is pressed.
Figure 4.3 on page 22 illustrates the basic navigation of the operating modes of the HMI.
