General Instructions

2.3 ABOUT THE CFW-11

The CFW-11 frequency inverter is a high performance product designed for speed and torque control of three-phase 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).

"Optimal Braking" function for the vector control, allowing the controlled braking of the motor and avoiding

the use of the braking resistor in some applications.

"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.

2.4 IDENTIFICATION LABELS FOR THE CFW-11

There are two nameplates on the CFW-11: one complete nameplate is affixed to the side of the inverter and a simplified one is located under the keypad. The nameplate under the keypad allows the identification of the most important characteristics of the inverter even if they are mounted side-by-side.

General Instructions

2.5 RECEIVING AND STORAGE

The CFW-11 is packaged and shipped in a cardboard box for models of frames B, and C.

The frame sizes D, E, F, G and H models are supplied packed in wooden boxes.

There is an identification label affixed to the outside of the package, identical to the one affixed to the side of the inverter.

To open the package:

1. Remove the package front cover.

2. Take out the polystyrene foam protection.

Verify whether:

1. The CFW-11 nameplate corresponds to the purchased model.

2. Any damage occurred during transportation.

Report any damage immediately to the carrier that delivered your CFW-11 inverter.

If the CFW-11 is not installed soon, store it in a clean and dry location (temperature between -25 °C and 60 °C (-13 °F and 140 °F), with a cover to prevent dust accumulation inside it.

ATTENTION!

When the inverter is stored for a long period, it becomes necessary to perform the capacitor reforming. Refer to the procedure in the Section 6.5 PREVENTIVE MAINTENANCE on page 6-9 in the Table

6.3 on page 6-9.
