GENERAL INFORMATION
This chapter defines the contents and purpose of this manual and describes
the main characteristics of the CFW-09 frequency inverter. Identification of
the CFW-09, receiving and storage requirements are also provided.
This Manual is divided into 9 Chapters, providing information to the user on
how to receive, install, start-up and operate the CFW-09:
Chapter 1: Safety Notices;
Chapter 2: General Information and Receiving the CFW-09;
Chapter 3: Information about the CFW-09 physical installation, electrical
connection (power and control circuit) and installation of optional
devices;
Chapter 4: Keypad (HMI) Operation (Human-Machine Interface - keyboard-
display);
Chapter 5: Start-up (Step-by-step);
Chapter 6: Detailed Programming Parameters Description;
Chapter 7: Diagnostics, troubleshooting, cleaning instructions and preventive
maintenance;
Chapter 8: Technical description of CFW-09 optional devices and
accessories;
Chapter 9: Technical specifications (electrical and mechanical).
This Manual provides information for the correct use of the CFW-09. The
CFW-09 is very flexible and allows for the operation in many different modes
as described in this manual.
As the CFW-09 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-09 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 Version CFW-09,
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 due to minor software revisions. The operation of
the CFW-09 with these software revisions are still covered by this version of
the Manual.
The Software Version can be read in the Parameter P023.
The CFW-09 is a high performance Variable Frequency Inverter that permits
the control of speed and torque of a three-phase AC induction motor. The
technological advantage of the CFW-09 is due to the “Vectrue” technology
that provides the following benefits:
Programmable scalar (volts/Hz) or Vector Control with the same product;
Vector Control can be programmed for “Sensorless” (that means that
standard motors can be controlled without encoder feedback), or “Closed
Loop” (with an encoder attached to the motor shaft);
