Safety Instructions

ATTENTION!

When in operation, electric energy systems – such as transformers, converters, motors and
cables – generate electromagnetic fields (EMF), posing a risk to people with pacemakers or implants
who stay in close proximity to them. Therefore, those people must stay at least 2 meters away from
such equipment.

2.2 TERMS AND DEFINITIONS

Regenerative Frequency Converter: three-phase switching frequency converter “boost type” (amplifier)

that converts the AC voltage from the power supply to a DC voltage (DC Link). It has the capability of
absorbing the energy of the power supply (AC) or to recover the energy back to the power supply, being
used as a DC voltage source to supply voltage to several output inverter.

Output inverter: frequency inverter fed by the DC link bus bar supplied by the regenerative converter. It
is responsible for the motor control.

Normal Duty Cycle (ND): converter duty cycle that defines the maximum continuous operation current
(I

2.3 ABOUT THE CFW-11M RB

The regenerative frequency converter is a bidirectional three-phase boost type AC/DC converter that
generates higher DC voltage than the line peak voltage. These converter are commonly known as AFE
(Active Front End) drives. The CFW-11M RB line utilizes the “RB” sulfix which states for Regenerative Braking
because it has the natural capacity of allowing the energy to flow from the converter to the power supply
when the motor is braking. The DC voltage generated by the regenerative converter is used to feed other
inverter power units that are controlling three-phase motors.

The CFW-11M RB regenerative converter is a high performance product that allows three-phase power
supply rectification with the following advantages:

; Low input current harmonic distortion.

; Capacity of recovering energy back to the power supply (regeneration) allowing high braking torque levels.

The CFW-11M RB line presents a modular structure with the possibility of assembling up to five power units
(UP11 - Books), one control unit (UC11) and interconnection cables. The control unit (UC11) is able to
control up to 5 (five) UP11’s.

The UP11 are directly feed via DC link bus bar and the UC11 is fed via the +24 Vdc power supply. Figure

2.1 shows an application sample.

The UP11 power units control is done by the UC11 control unit. The control unit is composed by the CFW-11M
RB control rack line, the IPS1 board and the CSR11 synchronism board. The IPS1 board exchange signals
with all UP11 units. The CSR11 synchronism board supervises the power supply, measuring the voltage values
and synchronizing the control.

General Instructions

The CFW-11M RB can be provided as a complete panel (AFW-11M RB) or as a panel mounting kit for
local assembly in a panel. The output inverter stage (CFW-11M) is needed for the mounting kit assembly.

The panel mounting kit is composed by the control unit set and the power units (UP11), which quantity
varies according to the CFW-11M RB model. The control unit set is composed by the control unit (UC11),
the cable set needed for the connection between the IPS1 board and the power units and the ribbon cable
to connect the IPS1 board to the CC11 RB board.

2-10 | CFW-11M RB

General Instructions

In order to open the box:

1. Put the control set box on a table with the help of two people; for the power units put the box on the
floor.

2. Open the wood crate.

3. Remove all the packing material (the cardboard or styrofoam protection) before removing the converter.

Check the following items once the converter is delivered:

; Verify that the product identification label corresponds to the model number on your purchase order.

; Inspect the product for external damage during transportation.

In case of any damage, immediately report it to the carrier responsible for delivering your product.

If the products are not installed immediately, store them in a clean and dry place (temperature between

-25 °C (-13 °F) and 60 °C (140 °F)) with a cover to prevent the contamination with dust.

ATTENTION!

Capacitor reforming is required if the converter or power units are stored for long periods of time
without power. Refer to the procedures in item 6.5 - table 6.3.

connections between the IPS1 and the power units, and the flat cable that connects the IPS1 board to the
CC11 RB control board.

3.3 MECHANICAL INSTALLATION

The power units must be properly secured in the drive cabinet, making it possible the easy withdrawal and
reinsertion in case of maintenance. The fastening must also be done so that it prevents panel transportation
damage.

The “Panel Mounting Rack” accessory simplifies the mounting of the power units and allows their simple
fastening and movement. Refer to the section 7.1 for more details.

3.4 ELECTRICAL INSTALLATION

DANGER!

The following information is merely a guide for proper installation. Comply with applicable local
regulations for electrical installations.

DANGER!

Make sure the AC power supply is disconnected before starting the installation.

∅4.0 [0.16] (3X)

ATTENTION!

The CFW-11M RB can be connected in circuits with symmetrical short circuit capability up to
150000 Arms (480 V/690 V maximum).

ATTENTION!

Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit
protection must be provided in accordance with applicable local standards.

3.4.1 Pre-charge Circuit

The resistors of the pre-charge circuit must be sized according to the following criteria:

- Maximum voltage.

- Maximum energy.

- Power overload capacity of the resistors during the pre-charge period (energy dissipation capacity).

The characteristics of the resistors must be obtained with their manufacturer.
