2 GENERAL INSTRUCTIONS

2.1 ABOUT THE MANUAL

The purpose of this manual is to provide the basic information needed to install, start-up in
the V/f control mode (scalar), and troubleshoot the most common problems of the CFW700
frequency inverter series.
ATTENTION!
The operation of this equipment requires installation instructions and detailed
operation provided in the user's manual, programming manual and manuals/
guides for kits and accessories. The user's manual and the parameters quick
reference are supplied in a hard copy together with the inverter. The user guides
are also provided in a hard copy along with the kit/accessories. The other
manuals are available at www.weg.net. A printed copy of the files available on

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), V V W 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).
