2.2 ABOUT THE CFW100
The CFW100 frequency inverter is a high-performance product which allows speed and torque
control of three-phase induction motors. This product provides the user with the options of vector
(VVW) or scalar (V/f) control, both programmable according to the application.
In the vector mode (V V W ), the operation is optimized for the motor in use, obtaining a better
performance in terms of speed regulation.
The scalar mode (V/f) is recommended for simpler applications, such as the activation of most
pumps and fans. In such cases it is possible to reduce the losses in the motor and the inverter
using the “V/f Quadratic”, which results in energy savings. The V/f mode is used when more than
a motor is activated by an inverter simultaneously (multimotor applications).
The main components of the CFW100 can be viewed in the block diagram of figure 2.1.

3.2.2 Circuit Breakers, Fuses, Grounding and Power
ATTENTION!
Use proper cable lugs for the power and grounding connection cables. Refer to
table B.1 for recommended wiring, circuit breakers and fuses.
Keep sensitive equipment and wiring at a minimum distance of 0.25 m (9.85 in) from
the inverter and from the cables connecting the inverter to the motor.
It is not recommended the use of mini circuit breakers (MDW), because of the
actuation level of the magnet.
ATTENTION!
Residual differential interrupter (DR):
When used in the inverter supply, it must have a pick-up current of 300 mA.
Depending on the installation conditions, such as motor cable length and type,
multi-motor drive, etc., the DR interrupter may trip. Check with the manufacturer
the most suitable type for operation with inverters.
NOTE!

3.2.3.1 Input Connections
DANGER!
Provide a disconnect device for the inverter power supply. This device must cut off
the power supply whenever necessary (during maintenance for instance).
ATTENTION!
The power supply that feeds the inverter must have a grounded neutral.
NOTE!
The input power supply voltage must be compatible with the inverter rated voltage.
Power factor correction capacitors are not needed at the input (L/L1, N/L2) and
must not be installed at the output (U, V, W).
Power supply capacity
The CFW-11 is suitable for use in a circuit capable of delivering not more than 30.000 Arms
symmetrical (200 to 240 V).
In case the CFW100 is installed in power supplies with current capacity over 30.000 Arms,
it is necessary to use proper protection circuits for those power supplies, such as fuses or
circuit breakers.
3.2.3.2 Power Supply Reactance
In a general way, the inverters of the CFW100 line can be installed directly in the power supply,
without reactance in the supply. However, check the following:
In order to prevent damages to the inverter and assure the expected useful life, you must
have a minimum impedance that provides a line voltage drop of 0.5 %. If the line impedance
(due to the transformers and cabling) is below the values listed in this table, we recommend
the use of a line reactance.

CFW100 | 19
Installation and Connection
English
For the calculation of the line reactance necessary to obtain the desired percentage voltage
drop, use:
L = 1592 . ΔV . Ve[ μH]
Ie, rat . f
seeing that:
ΔV - desired line drop, in percentage (%);
Ve- phase voltage in the inverter input, in volts (V);
Ie, rat - rated current of the inverter input;
f - line frequency.
3.2.3.3 Output Connections
ATTENTION!
The inverter has an electronic motor overload protection that must be adjusted
according to the driven motor. When several motors are connected to the same
inverter, install individual overload relays for each motor.
The motor overload protection available in the CFW100 is in accordance with
the UL508C standard. Note the following information:
1. Trip current equal to 1.2 times the motor rated current (P401).
2. When parameters P156, P157 and P158 (Overload current at 100 %, 50 %
and 5 % of the rated speed, respectively) are manually set, the maximum
value to meet the condition 1 is 1.1 x P0401.
ATTENTION!
If a disconnect switch or a contactor is installed at the power supply between the
inverter and the motor, never operate it with the motor spinning or with voltage at
the inverter output.
The characteristics of the cable used to connect the motor to the inverter, as well as its
interconnection and routing, are extremely important to avoid electromagnetic interference in
other equipment and not to affect the life cycle of windings and bearings of the controlled motors.
Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.),
according to item 3.2.6 - Distance for Cable Separation.
