2.2 ABOUT THE CFW701
The CFW701 frequency inverter is a high performance product designed for speed and torque
control of threephase induction motors. The main characteristic of this product is the “Vectrue”
technology, which has the following advantages:
Scalar control (V/f), VVW, or vector control programmable in the same product.
The vector control may be programmed as “sensorless” (which means standard motors
without using encoders).
The “sensorless” control allows high torque and fast response, even in very low speeds or at
the starting.
“Optimal Braking” function for the vector control, allowing the controlled braking of the motor
and avoiding external braking resistor for some applications.
“Self-Tuning” feature for vector control. It allows the automatic adjustment of the regulators
and control parameters from the identification (also automatic) of the motor parameters and
load.
The main components of the CFW701 can be viewed in Figure A.1 on page 138.

(frame size E), it is necessary to apply current reduction of 2 % for every degree Celsius (or
1.11 % each °F) up to Ta.
Humidity: from 5 % to 95 % non-condensing.
Altitude: up to 1000 m (3.300 ft) - standard conditions (no derating required).
From 1000 m to 4000 m (3.300 ft to 13.200 ft) - current derating of 1 % each 100 m (or 0.3 %
each 100 ft) above 1000 m (3.300 ft) altitude.
From 2000 m to 4000 m (6.600 ft to 13.200 ft) above sea level - maximum voltage reduction
(240 V for 200...240 V models, 230 V for 220...230 V models, 480 V for 380...480 V models
and 600 V for 500 ...600 V models) of 1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
English
Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution.
Condensation shall not originate conduction through the accumulated residues.
3.1. 2 Mounting Considerations
External dimensions, fixing holes position and net weight of the inverter are presented at Figure
B.2 on page 169 and Figure B.3 on page 171. Please refer to Figure B.4 on page 172 to
Figure B.10 on page 178 for more details of each inverter frame size.
Install the inverter upright on a flat surface. First place the screws on the surface where the
drive is going to be installed, install the drive and then tighten the screws.
Frame size E inverters with N1 option (CFW701E...N1...):
After fixing the inverter, install the upper Nema 1 kit on the inverter using the two M8 screws
provided with the product.
CFW701 | 9
Installation and Connection
Let the minimum clearances specified in Figure B.3 on page 171 in order to allow air circulation
for cooling. It is possible to assembly frame sizes A, B and C inverters with IP20 protection
degree (CF W701… 20…) side by side without lateral spacing, i.e., with the D distance presented
English
in Figure B.3 on page 171 equal to zero.
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 B.3 on page 171) and provide an air deflecting
plate so that the heat rising up from the bottom inverter does not affect the
top inverter.
Provide conduit for physical separation of the signal, control, and power
conductors (refer to section 3.2 ELECTRICAL INSTALLATION on page 10).
Please refer to Figure B.3 on page 171 for surface and flange mounting data. The inverter
dissipated power at rated condition for surface and flange mounting is presented in Table B.4
on page 152. Remove the drive mounting brackets for flange mounting. The protection degree
of the inverter outside the panel is IP55 for flange mounting. It is necessary to provide proper
seal for the opening where the inverter is installed to ensure the protection degree of the panel.
Example: sealing with silicone.
Please refer to Figure A.4 on page 141 for more details on the access to the control and
power terminals.

Installation and Connection
ATTENTION!
The power supply that feeds the inverter shall have a solid grounded neutral.
In case of IT networks, follow the instructions described below.
ATTENTION!
In order to be able to use the CFW701 with built-in C3 RFI filter (CFW701…
C3…) in IT networks (neutral conductor not grounded or grounded via a high
ohmic value resistor) or in corner-grounded delta systems, it is necessary to
remove some RFI filter components (capacitor for frame sizes A, B, C and
D and capacitor and the MOV for frame size E) connected to the ground by
removing the screws indicated in Figure A.6 on page 142 for inverter frame
sizes A, B, C and D and changing the position of the J1 jumper on the PRT1
board from (XE1) to “NC” (XIT), according to the Figure A.6 on page 142
for inverter frame size E.
AC power supply considerations
Suitable for use on a circuit capable of delivering not more than 100.000 A
Ampères at 240 V, 480 V or 600 V maximum, when protected by Class J fuses (for 240 V
symmetrical
rms
and 480 V models) or special purpose fuses (for 600 V).
In case the CFW701 is installed in power supplies with current capacity higher than 100.000 A
it is necessary to provide adequate protections circuits such as fuses or switches.

3.2.3.2 Dynamic Braking (standard built-in for frame sizes A, B, C and D and optional built-in for frame size E - CFW701...DB...)
Refer to Table B.1 on page 148, Table B.2 on page 149 and Table B.3 on page 150 for
the following dynamic braking specifications: maximum current, resistance, RMS current and
cable gauges.
The power rating of the dynamic braking resistor is a function of the deceleration time, the load
inertia and the resistant torque.
English
,
Dynamic braking installing procedure:
Install the braking resistor between the power terminals DC+ and BR.
Use twisted cable for the connection. Separate these cables from the signal and control
cables.
Size the cables according to the application, respecting the maximum and effective currents.
If the braking resistor is installed inside the inverter cabinet, consider its additional dissipated
energy when sizing the cabinet ventilation.
The thermal protection of the dynamic braking resistor must be provided externally using a
thermal relay in series with the resistor and/or a thermostat in contact with the resistor frame,
connected so as to switch the input power supply of the inverter, as shown in Figure 3.3 on
page 16.

ATTENTION!
The inverter has an electronic motor overload protection that shall 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 for the CFW701 is in accordance
with UL508C as per the following information:
- Trip current equal to 1.25 times the motor rated current (P0401) adjusted
in the oriented start-up menu.
- The maximum value of P0398 (Motor Service Factor) is 1.15.
- Parameters P0156, P0157 and P0158 (Overload Current at 100 %,
50 % and 5 % of the rated speed, respectively) are automatically adjusted
when the parameters P0401 (Motor Rated Current) and/or P0406 (Motor
Ventilation) are changed on the “Oriented Start-up” menu. If the parameters
P0156, P0157 and P0158 are set manually, the maximum allowed value
is 1.05 x P0401.
Installation and Connection
ATTENTION!
If a disconnect switch or a contactor is installed between the inverter and the
motor, never operate them with a spinning motor or with voltage at the inverter
output.
The characteristics of the cable used for the inverter and motor interconnection, as well as
the physical location are extremely important to avoid electromagnetic interference in other
equipment and to not affect the life cycle of motor windings and motor bearings controlled by
inverters.
Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.),
according to item 3.2.6 Cable Distances on page 22.
Connect a fourth cable between the motor ground and the inverter ground.
When using shielded cables for connecting the motor:
Follow the recommendations of IEC60034-25.
Use low impedance connection to high frequencies to connect the cable shield to ground.
Using parts supplied with the drive. See item below.
For inverter frame sizes A, B and C there is an accessory called “Shielding kit for power
cables PCSx-01” (see section 7.2 ACCESSORIES on page 37), which can be mounted at
the bottom of the cabinet – the Figure 3.4 on page 17 shows an example. The shielding
kit for power cables PCSx-01 goes along with inverters with optional internal C3 RFI filter
(CFW701...C3...). The grounding for the motor cable shield on inverter frame sizes D and E
is already provided in the standard inverter cabinet. This is also provided on the “Nema1
Kits (KN1x-01)” of the inverter frame sizes A, B and C.
For frame sizes B and C with degree of protection IP55, the accessory "PCSC-03 power
cable shield kit" is available, and for frame size D and E with degree of IP55 use the standard
accessories for shielding. The PCSC-03 shield kit comes with the inverter as optional item N12.
