2.2 TERMS AND DEFINITIONS USED IN THE MANUAL
Normal Duty (ND): operating duty of the inverter that defines the maximum current values for continuous operation
Inom-ND and overload of 110 % for one minute. It is selected by programming P0298 (Application) = 0 (Normal Duty

Heavy Duty (HD): operating duty of the inverter that defines the maximum current values for continuous operation
Inom-HD and overload of 150 % for one minute. It is selected by programming P0298 (Application) = 1 (Heavy Duty
(HD)). It should be used to drive motors which are subject, in the application, to high overload torques in relation
to its rated torque, when operating at constant speed, at the start, at the acceleration or at the deceleration.
Inom-HD:inverter rated current for operation under heavy duty (HD). Overload: 1.5 x Inom-HD / 1 minute.

Unbalance at power unit X - phase Y = .100
IYX - IYAVG
IYAVG
IYAVG =IY1 + IY2 + ... + IYN
N
Where:
N = number of the power units.
IYN = current of phase Y (U, V or W) of the power unit N (P0815 to P0829).

Pre-Charge Circuit: it loads the capacitors of the DC link with limited current, avoiding high current peaks at the
inverter energization.
DC Link: intermediate circuit of the inverters; voltage in direct current obtained by rectifying the alternate supply
voltage or through an external power supply; it supplies the output inverter bridge of the inverters composed of
IGBTs.

DC-: negative terminal of the DC Link.
Arm U, V and W: 2-IGBT set of the inverter output phases U, V and W.

2.3 ABOUT THE CFW11W G2
CFW11W G2 inverters are the second generation of CFW11W inverters. The main differences in relation to the
previous generation are the following:
Smaller. CFW-11M G2 is shorter, slimmer and less deep than the CFW11W, allowing the installation of 3 UP11W
G2 in panels featuring 800 mm wide, 2000 mm high and 800 mm deep columns.
More modern. State-of-the-art components increased the inverter power.
The CFW11W G2 is a high-performance, water-cooled product which enables speed and torque control of three-
phase induction motors. The main characteristic of this product is the "Vectrue" technology, which provides the
following advantages:
High compactness and power density.
Programmable Vector, Scalar (V/f) or VVW control on the same product.
The vector control can be programmed as sensorless (which means standard motors, without requiring encoder)
or as vector control with encoder on the motor.
The sensorless vector control allows high torque and fast response, even at very low speeds or at the start.
The vector with encoder control enables high precision in the drive throughout the speed range (even stopped
motor).
"Optimal Braking" function for vector control, allowing the controlled braking of the motor, eliminating the use of
braking resistor in some applications.
"Self-Tuning" function for vector control: It allows the automatic setting of control parameters and regulators
based on the identification (also automatic) of the motor parameters and load.
The CFW11W G2 inverters present a modular design, with configurations from one to five power units (UP11W
G2), one control unit (UC11 G2) and wiring cables. The modular assembly increases the reliability of the inverter
and simplifies its maintenance. There is a single control unit (UC11 G2) which can control up to 5 UP11Ws G2.
These inverters are water-cooled, being more compact than other inverters.
The UP11Ws and UC11 G2 are supplied by a power supply of +24 Vdc. Figure 2.1 on page 2-5 shows a general
diagram of the inverter, considering the configuration with three UP11Ws connected in parallel.
The control of the power units is done by the UC11 G2 control unit. The control unit contains the control rack of
the CFW11 line and the ICUP board. This board sends signals to all UP11Ws G2 (PWM, control signals, etc.), and
receives signals from them (current, voltage feedback, etc.).

NOTE!
To assemble the complete drive, several additional items are necessary, such as input rectifier, fuses
on the DC power supply of each UP11W power unit, external pre-charge circuit and input reactance
with minimum input impedance of 3 % when it is a 6-pulse rectifier.
NOTE!
It is not necessary to include a current transformer (CT) in the drive for protection against short circuit
to the ground in the output, since each UP11W G2 has its own internal protection.

3 INSTALLATION AND CONNECTION
This chapter describes the electrical and mechanical installation procedures for the CFW11W G2. The directions
and suggestions must be observed so as to ensure the safety of people and equipment, and the proper operation
of the inverter.
3.1 MECHANICAL INSTALLATION
