4 ABOUT THE CFW500
The frequency inverter CFW500 is a high-performance product which allows the 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 VW), the operation is optimized for the motor in use, obtaining a better per formance in terms
of speed regulation. The scalar mode ( V/f) is recommended for simpler applications, such as the activation of most
pumps and fans. The V/f mode is used when more than a motor is activated by an inver ter simultaneously
(multimotor applications).

L/L1, N/L2, L3 (R,S y T): AC power supply. Some models of voltage 200-240 V (see option of models in Table 10)
can operate in 2 or 3 phases (single-phase/ three-phase inverters) without derating of the rated current. In this case,
the AC power supply can be connected to two of the three input terminals without distinction. For the single-phase
models only, the power voltage must be connected to L /L1 and N/L 2.
U, V, W: connection for the motor.
-UD: negative pole of the voltage of the DC bus.
+UD: positive pole of the voltage of the DC bus.
BR: connection of the brake resistor.
DCR: connection to the external DC link inductor (optional). Only available for models 28 A, 33 A, 47 A and 56 A /
200-240 V and 24 A, 31 A, 39 A and 49 A / 380-480 V.
9.2 Power and Grounding Wiring, Circuit Breakers and Fuses
ATTENTION!
Use proper cable lugs for the power and grounding connection cables. Refer to Table 10 for
recommended wiring, circuit breakers and fuses.
Keep sensitive equipment and wiring at a minimum distance of 0.25 m from the inverter and from
the cables connecting the inverter to the motor.
It is not recommended the use of mini circuit breakers (MDU), because of the actuation level
of the magnet.
ATTENTION!
Residual Current Device (RCD):
When installing an RCD to guard against electrical shock, only devices with a trip current of
300 mA should be used on the supply side of the inverter.
Depending on the installation (motor cable length, cable type, multimotor configuration, etc.),
the RCD protection may be activated. Contact the RCD manufacturer for selecting the most
appropriate device to be used with inverters.
NOTE!
The wire gauges listed in Table 10 sare orientative values. Installation conditions and the maximum
permitted voltage drop must be considered for the proper wiring sizing.
In order to meet UL requirements, use ultra fast (for frame sizes A , B and C), and use fuse type J
or circuit breaker (for frame sizes D and E) fuses at the inverter supply with a current not higher
than the values presented in Table 10.

11 PREPARATION AND POWERING UP
DANGER!
Always disconnect the general power supply before making any connection.
1. Check if the power, grounding and control connections are correct and firm.
2. Remove all materials left from the inside of the inverter or drive.
3. Check if the motor connections and if the motor current and voltage match the inverter.
4. Mechanically uncouple the motor from the load. If the motor cannot be uncoupled, be sure that the turning in any
direction (clock wise or counterclockwise) will not cause damage s to the machine or risk of accidents.
5. Close the covers of the inverters or drive.
6. Measure the voltage of the input power supply and check if it is within the permitted range, as presented in
Chapter 13 TECHNICAL SPECIFICATIONS
7. Power up the input: close the disconnecting switch.
8. Check the success of the powering up:

12 OPTIONAL KITS AND ACCESSORIES
12.1 RFI Filter
Inver ters with code CFW500...C... are used to reduce the disturbance conducted from the inverter to the main power supply
in the hi gh freque ncy band (> 150 kHz). It is n ecessar y to meet the m aximum l evels of cond ucted emis sion of elec tromagnet ic
compatibility standards, such as EN 61800-3 and EN 55011. For fur ther details, refer to Chapter 10 IINSTALL ATIONS
ACCORDING TO EUROPEAN DIRECTIVE OF ELECTROMAGNETIC COMPATIBILITY.
ATTENTION!
When inverters with internal RFI filter are used in IT networks (neuter not grounded or grounded through
a high ohmic value resistor), always set the grounding switch of the capacitors of the internal RFI filter to
the NC position, since those kinds of network cause damage to the filter capacitors of the inverter.
12.2 Accessories
The accessories are hardware resources that can be added in the application. Thus, all models can receive all the
options presented.
The accessories are incorporated to the inverters in an easy and quick way by using the concept "Plug and Play".
When an accessor y is connected to the inverter, the control circuitr y identifies the model and informs the code of
the accessory connected in parameter P0027. The accessory must be installed or modified with the inverter de-
energized. They may be ordered separately, and are sent in their own package containing the components and
manuals with detailed instructions for their installation, operation and setting.

9.3.3 Dynamic Braking
NOTE!
The dynamic braking is available from frame B. For installation information, refer to Item 3.2.3.4
Dynamic Braking of the user’s manual, available on www.weg.net.
9.3.4 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 CFW500 is in accordance with the UL508C
standard. Note the following information:
1. Trip current equal to 1.2 times the motor rated current (P0401).
2. When parameters P0156, P0157 and P0158 (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 turning 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 inter ference in other equipment and not to af fect 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
9.3.7 Cable Separation Distance.
Connect a fourth cable between the motor ground and the inverter ground.
When using shielded cables to install the motor:
Follow the safety recommendations of IEC 60034-25.
Use the low impedance connection for high frequencies to connect the cable shield to the grounding. Use parts
supplied with the inverter.
The accessory "CFW500-KPCSx power and control cable shielding kit" can be mounted in the lower par t of the
cabinet. Figure 5 shows a detailed example of the connection of the power supply and the motor cable shield
to the accessory CFW500-KPCSA. Besides, this accessory allows the connection of the control cable shield.

9.3.5 Grounding Connections
DANGER!
The inverter must be connected to a protection grounding (PE).
Use grounding wiring with a gauge at least equal to that indicated in Table 10.
The ma ximum tightening torque of the grounding connections is of 1.7 N.m (15 lbf.in).
Connect the grounding points of the inverter to a specific grounding rod, or specific grounding
point or to the general grounding point (resistance ≤ 10 Ω).
The neuter conductor that powers up the inverte r must be solidly grounded; howeve r, this
conductor must not be used to ground the inverter.
Do not share the grounding wiring with other equipment that operate with high currents (e.g. high
power motors, soldering machines, etc.).
9.3.6 Control Connections
The control connections (analog input/output, digital input/output and interface RS485) must be performed
according to the specification of the connector of the plug-in module connected to the CFW500. Refer to the guide
of the plug-in module in the package of the product. The typical functions and connections for the CFW500-IOS
standard plug-in module are shown in Figure 6.

Figure 6: Signals of the connector of the CFW500-IOS plug-in module
For the correct connection of the control, use:
1. Gauge of the cables: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2. Maximum torque: 0.5 N.m (4.50 lbf.in).
3. FWiring of the plug-in module connector with shielded cable and separated from the other wiring (power, command
in 110 V / 220 Vac, etc), according to Item 9.3.7 Cable Separation Distance.
4. Relays, contactors, solenoids or coils of electromechanical brake installed close to the inverters may occasionally
generate interference in the control circuitry. To eliminate this effect, RC suppressors (with AC power supply) or
freewheel diodes (with DC power supply) must be connected in parallel to the coils of these devices.
