: inverter rated current for use with normal duty cycle (ND = Normal Duty).
Overload: 1,1 x I
nom-ND
/ 1minute.
Heavy Duty Cycle (HD): inverter duty that defines the maximum current values for continuous duty I
nom-HD
and
an overload of 150 % during 1 minute. It is selected by programming P0298 (Application) = 1 (Heavy Duty – HD). It
must be used for driving motors that are subject in that application to high torques with respect to their rated torque,
when operating at constant speed, during start, acceleration or deceleration.
I
nom-HD
: inverter rated current for use with heavy duty cycle (HD = Heavy Duty).
Overload: 1,5 x I
nom-HD
/ 1minute.
Rectier: the input circuit of the inverters that converts the input AC voltage into DC, it is made of thyristors
and power diodes.
Pre-charge circuit: it charges the DC link capacitors with a limited current, thus avoiding higher current peaks
when powering the inverter.
DC Link: inverter intermediate circuit; DC voltage obtained from the rectification of the AC input voltage or
from an external power supply. It feeds the inverter output IGBT bridge.
U, V and W Arms: set of two IGBTs forming the inverter output phases U, V and W.
IGBT: "Insulated Gate Bipolar Transistor"; it is the output inverter bridge basic component, working as an
electronic switch either in the saturated (closed switch) or in the cut off mode (open switch).
Braking IGBT: it works as a switch to activate the braking resistances; it is controlled by the voltage level on
the DC link.

2.3 ABOUT THE CFW-11
The CFW-11 is a high performance variable frequency drive that makes it possible the control of speed and
torque of three-phase AC induction motors. The central characteristic of this product is the "Vectrue" technology,
which presents the following advantages:
(V/f), V VW or vector control programmable in the same product.
The vector control can be programmed as "sensorless" (which means standard motors, without the need of
encoder) or vector control with motor encoder.
The "sensorless" vector control allows high torque and fast response, even at very slow speeds or during
starting.
The "vector control with encoder" allows very high speed accuracy and control for the entire speed range
(speed control down to 0 rpm).
The "Optimal Braking" function for the vector control allows a controlled motor braking, eliminating in some
applications the braking resistor.
The vector control "Self-Tuning" function allows the automatic setting of the regulators and control parameters,
from the identification (also automatic) of the motor and load parameters.

CFW-11 | 2-15
2.6 RECEIVING AND STORAGE
The CFW-11 inverters from the frame sizes 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 CFW-11.
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.
If any problems are detected, contact the carrier immediately.
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 on Table 6.3
on page 6-9.

3 INSTALLATION AND CONNECTION
This chapter describes the CFW-11 electrical and mechanical
installation procedures. The guidelines and suggestions must be
followed aiming personnel and equipment safety, as well as the
proper operation of the inverter.
3.1 MECHANICAL INSTALLATION
3.1.1 Environmental Conditions
NOTE!
The inverter are designed for indoor use only.
Avoid:
Direct exposure to sunlight, rain, high humidity, or sea-air.
Inflammable or corrosive gases or liquids.
Excessive vibration.
Dust, metallic particles, and oil mist.
Environment conditions for the operation of the inverter:
Temperature (standard conditions (surrounding the inverter), no frost allowed):
- 10 °C to 45 °C (50 °F to 113 °F) for frame sizes F and G (except models 720 A and 760 A).
- 10 °C to 40 °C (50 °F to 104 °F) for frame sizes G (only models 720 A and 760 A) and H.
From 40 °C to 45 °C (50 °F to 113 °F) for frame size G (only model 720 A): 2 % of current derating for each
celsius degree above maximum temperature as specified in item above.
From 40 °C to 45 °C (50 °F to 113 °F) for frame sizes G (only model 760 A) and H: 1 % of current derating
for each celsius degree above maximum temperature as specified in item above.
From 45 °C to 55 °C (113 °F to 131 °F) for frame sizes F, G and H: 2 % of current derating for each Celsius
degree above maximum temperature as specified in item above.
Maximum altitude: up to 1000 m (3.300 ft) - 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) (or 0.3 %
each 100 ft) above 1000 m (3.300 ft) altitude.
Installation and Connection
3
3-2 | CFW-11
From 2000 m to 4000 m (6.600 ft to 13.200 ft) above sea level - derating of maximum voltage of 1.1 %
for each 100 m (330 ft) above 2000 m (6.600 ft).
Humidity: from 5 % to 95 % non-condensing.
Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution. Condensation
shall not originate conduction through the accumulated residues.
3.1.2 Positioning and Mounting
Consult the inverter weight at the Table 8.1 on page 8-2, Table 8.2 on page 8-3 and Table 8.3 on page
8-5.
Mount the inverter in the upright position on a flat and vertical surface.
External dimensions and fixing holes position according to the Figure 3.1 on page 3-3. Refer to the Section
8.5 MECHANICAL DATA on page 8-8 for more details.
First mark the mounting points and drill the mouting holes. Then, position the inverter and firmly tighten the
screws in all four corners to secure the inverter.
Minimum mounting clearances requirements for proper cooling air circulation are specified in Figure 3.2 on
page 3-4.
Do not install heat sensitive components right above the inverter.
ATTENTION!
When arranging two or more inverters vertically, respect the minimum clearance A + B (Figure 3.2
on page 3-4) and provide an air deflecting plate so that the heat rising up from the bottom inverter
does not affect the top inverter.
ATTENTION!
Provide conduit for physical separation of the signal, control, and power conductors (refer to Section
3.2 ELECTRICAL INSTALLATION on page 3-8).
