diodes.
Pre-Charge Circuit: it charges the DC link capacitors with a limited current, thus avoiding higher current peaks
when powering the inverter.

an external power supply. It feeds the inverter output IGBTs bridge.
DC+: Positive terminal of the DC Link.
DC-: Negative terminal of the DC Link.
U, V, W Arms: set of two IGBTs forming the inverter output phases U, V, and W.
IGB T: insulated Gate Bipolar Transistor, basic component of the output inverters. They work as an electronic
switch in the saturated (closed switch) and cut-off (open switch) modes.

2.3 ABOUT THE CFW-11M G2
The CFW-11M G2 inverters are the second generation of the CFW-11M inverters. The main differences in relation
to the previous generation are the following:
2
Smaller. The CFW-11M G2 is shorter and slimmer than the CFW-11M, allowing the installation of 3 UP11 G2 in
panels featuring 800 mm wide and 2000 mm high columns.
More modern. State-of-the-art components increased the inverter power.
The CFW11 G2 is a high-performance 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.
Scalar control (V/f), VVW or vector control programmable in 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 allows high speed precision for the whole speed range (even with a standstill
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 CFW-11M G2 inverters present a modular structure, with configurations from one to five power units (UP11
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 UP11s G2.
The UP11s and UC11 G2 are supplied trough 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 UP11s 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 CFW-11 line and the ICUP board. This board sends signals to all UP11 G2 (PWM, control signals, etc.), and it
receives signals from them (current, voltage feedback, etc.).

NOTE!
Several additional items are necessary for mounting the complete drive, such as input rectifier, fuses
in the DC supply of each power unit UP11, external pre-charge circuit and an input reactor with a
minimum impedance of 3 % in case of a 6 pulse rectifier.
NOTE!
The inclusion of a current transformer (CT) in the drive for the output short-circuit to the ground
protection is not necessary because each UP11 has its own internal protection.

Installation and Connection
3 INSTALLATION AND CONNECTION
This chapter provides information on installing and wiring the CFW-11M G2. The instructions and guidelines listed
in this manual shall be followed to guarantee personnel and equipment safety, as well as the proper operation of
the inverter.
3.1 MECHANICAL INSTALLATION
The power units must be installed in the drive panel appropriately, allowing easy extraction and reinstallation in
case of maintenance. The mounting must be such to avoid damage during the panel transportation.
3.1.1 Environment Conditions
Avoid:
Direct exposure to sunlight, rain, high humidity, or sea-air.
Inflammable or corrosive liquids or gases.
Excessive vibration.
Dust, metal particles or oil suspended in the air.
Environment conditions for the operation of the inverter:
Ambient temperature: 0 °C to 45 °C (32 °F to 113 °F) - rated conditions (measured around the inverter). From
45 ºC to 55 ºC (113 °F to 131 °F) - 2 % of current derating for each Celsius degree above 45 ºC (113 °F).
Altitude: up to 1000 m (3.300 ft) above sea level – rated conditions.
From 1000 m to 4000 m (3.300 ft to 13.200 ft) – 1% of current derating for each 100 m (330 ft) above 1000 m
(3.300 ft) of altitude.
From 2000 m to 4000 m (6.600 ft to 13.200 ft) - maximum voltage (480 V for models 380...480 V and 690 V for
models 500...690 V) derating of 1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
3
Maximum altitude of up to 4000 m (13.200 ft).
Air relative humidity: 5 % to 95 % non-condensing.
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation must
not cause conduction of the accumulated residues.
3.1. 2 List of Components
For panel mounting of the CFW11M G2, it is necessary: a control set (UC11 G2), UP11 G2 power units and a cable
set to connect the UC11 G2 to the UP11 G2. Table 3.1 on page 3-1, Table 3.2 on page 3-2 and Table 3.3 on
page 3-2 present the list of components of the CFW-11M G2 inverter.

3.1.4 Panel Ventilation
The efficiency of the panel ventilation depends on the equipment installed inside the panel, such as fans, air inlets
and filters. The internal fan of the UP11 is not enough to cool the entire panel.

3.1.5 Panel Mounting of the UP11 G2
To install the UP11 G2 in panels, the following mounting accessories are necessary:
Rack 2 G2 allows the mounting of 1 or 2 modules side by side in 600 mm wide panels.
Rack 3 G2 allows the mounting of 1, 2 or 3 modules side by side in 800 mm wide panels.
