CHAPTER 1
SAFETY NOTICES
This manual contains necessary information for the correct use of the
CFW-10 Variable Frequency Drive.
This manual has been written for qualified personnel with suitable
training and technical qualification to operate this type of equipment.
The following Safety Notices will be used in this manual:
DANGER!
If the recommended Safety Notices are not strictly observed, it can
lead to serious or fatal injuries of personnel and/or material damage.
ATTENTION!
Failure to observe the recommended Safety Procedures can lead to
material damage.
NOTE!
The content of this manual supplies important information for the
correct understanding of operation and proper performance of the
equipment.
The following symbols may be attached to the product, serving as
Safety Notice:
High Voltages
Components sensitive to electrostatic discharge. Do not touch
them without proper grounding procedures.
Mandatory connection to ground protection (PE)
Shield connection to ground
DANGER!
Only qualified personnel should plan or implement the installation,
start-up, operation and maintenance of this equipment. Personnel
must review entire Manual before attempting to install, operate or
troubleshoot the CFW-10.
These personnel must follow all safety instructions included in this
Manual and/or defined by local regulations.
Failure to comply with these instructions may result in personnel injury
and/or equipment damage.

NOTICES IN THE
MANUAL

CHAPTER 1 - SAFETY NOTICES
NOTE!
In this manual, qualified personnel are defined as people that are
trained to:
1. Install, ground, power up and operate the CFW-10 according to
this manual and the local required safety procedures;
2. Use of safety equipment according to the local regulations;
3. Administer First Aid.
DANGER!
The inverter control circuit (CCP10, DSP) and the HMI-CFW-10 are
not grounded. They are high voltage circuits.
DANGER!
Always disconnect the supply voltage before touching any electrical
component inside the inverter.
Many components are charged with high voltages, even after the
incoming AC power supply has been disconnected or switched OFF.
Wait at least 10 minutes for the total discharge of the power capacitors.
Always connect the frame of the equipment to the ground (PE) at the
suitable connection point.
CFW-10 drive must be grounded appropriately for safety purposes
(PE).
ATTENTION!
All electronic boards have components that are sensitive to
electrostatic discharges. Never touch any of theelectrical components
or connectors without following proper grounding procedures. If
necessary to do so, touch the properly grounded metallic frame or
use a suitable ground strap.
NOTE!
Inverters can interfere with other electronic equipment. In order to
reduce this interference, adopt the measures recommended in
Section 3 “Installation”.
NOTE!
Read this entire manual carefully and completely before installing or
operating the CFW-10.
Do not apply High Voltage (High Pot) Test on the inverter!
If this test is necessary, contact the Manufacturer.

This chapter defines the contents and purposes of this manual and
describes the main characteristics of the CFW-10 frequency inverter.
Identification, receiving inspections and storage requirements are also
provided.
This Manual is divided into 9 Chapter, providing information to the
user on receiving, installation, start-up and operation:
Chapter 1 - Safety Notices.
Chapter 2 - General Informations and Receiving the CFW-10.
Chapter 3 - CFW-10 and RFI Filters - Mechanical and Electrical
Installation (power and control circuitry).
Chapter 4 - Using the Keypad (Human Machine Interface - HMI).
Chapter 5 - Start-up - Steps to follow.
Chapter 6 - Setup and Read-only Parameters-Detailed description.
Chapter 7 - Solving problems, cleaning instructions and preventive
maintenance.
Chapter 8 - CFW -10 Optional Devices - Description, technical
characteristics and installation.
Chapter 9 - CFW-10 ratings - Tables and technical information.
This Manual provides information for the correct use of the CFW-10.
The CFW-10 is very flexible and allows the operation in many different
modes as described in this manual.
As the CFW-10 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-10 is not used according to this
Manual.
No part of this Manual may be reproduced in any form, without the
written permission of WEG.
It is important to note the Software Version installed in the CFW-10,
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 1.0X applies to versions 1.00 to 1.09,
where “X” is a variable that will change dueto minor software revisions.
The Software Version can be read in the Parameter P023.

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 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).
Chapter 9 shows the different power lines and additional technical
information
The block diagram below gives a general overview of the CFW-10.

NOTE!
The Option field (S or O) defines if the CFW-10 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: CFW100040S2024ESZ = standard 4.0 A CFW-10 inverter, single-phase at 200 V to 240 V input with manual in English. If the CFW-10 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.
