GENERAL INFORMA TION
This chapter defines the contents and purposes of this manual and describes the main characteristics of the CFW-08 frequency inverter. Identification, receiving inspections and storage requirements are also provided.
2.1 ABOUT THIS MANUAL
This Manual is divided into 10 Chapter, providing infornation to the user on how receive, install, start-up and operate the CFW-08:
Chapter 1 - Safety Notices; Chapter 2 - General Information; Chapter 3 - Installation; Chapter 4 - Start-up; Chapter 5 - Keypad HMI) Operation; Chapter 6 - Detailed Parameter Description; Chapter 7 - Diagnostic and Troubleshooting; Chapter 8 - CFW-08 Options and Accessories; Chapter 9 - Technical S pecifications; Chapter 10 - Warranty Policy.
This Manual provides information for the correct use of the CFW-08. The CFW-08 is very flexible and allows for the operation in many different modes as described in this manual.
As the CFW-08 can be applied in several ways, it is impossible to describe here all of the application possibilities. WEG does not accept any responsibility when the CFW-08 is not used according to this Manual.
No part of this Manual may be reproduced in any form, without the written permission of WEG.
2.2 SOFTWARE VERSION
It is important to note the Software V ersion installed in the V ersion CFW­08, since it defines the functions and the programming parameters of the inverter. This Manual refers to the Software version indicated on the inside cover. For example, the Version 3.0X applies to versions 3.00 to 3.09, where “X” is a variable that will change due to minor software revisions. The operation of the CFW-08 with these software revisions are still covered by this version of the Manual.
The Software V ersion can be read in the Parameter P023.

GENERAL INFORMATION
2.3 ABOUT THE CFW-08
The CFW-08 is a high performance V ariable Frequency Drive that permits the control of speed and torque of a three-phase AC induction motor . T wo types of control are available in the same product:
Programmable scalar (Volts/Hz) control; Sensorless Vector Control (VVC: V oltage V ector Control).
In the vector control mode, the motor performance is optimized relating to torque and speed regulation. The "Self-Tuning" function, available in vector control, permits the automatic setting of the inverter parameter from the identification (also automatic) of the parameters of the motor connected at the inverter output. The V/F (scalar) mode is recommended for more simple applications such as pump and fan drives. In these cases one can reduce the motor and inverter losses by using the "Quadratic V/F" option, that results in energy saving. The V/F mode is also used when more than one motor should be driven simultaneously by one inverter (multimotor application).
There are two CFW-08 versions:
Standard: it has 4 digit al inputs (DIs), 1 analog input (AI) and 1 relay output. CFW-08 Plus: compared to the standard version it has one additional analog input and one additional relay output. It has also an analog output (AO).
For power ratings and further technical information, see Chaper 9.

GENERAL INFORMATION
Product Appearance
Besides the internal electronics, also the exterrnal product appearance have changed, which are:
- the frontal lettering on the plastic covers (formerly: µline, now: CFW-08 vector inverter);
- WEG logo is now indicated on all accessories of the CFW-08 line (keypad, communication modules etc).
Figure below makes a comparison:

(b) CFW-08
Figure 2.3 - Comparison between µline a CFW-08 appearance
Version of Software
The new CFW-08 starts with Software V ersion V3.00. Thus, the software Versions V1.xx and V2.xx are exclusive for µline. Besides the inverter control has been implemented in a DSP (Digital Signal Processor), which enables a more sophisticated control with more parameters and functions.
Accessories
With the migration from the 16 bits microcontroller to the DSP of the new CFW-08, the power supply of the electronic circuits had to be changed from 5V to 3.3V . Consequently , the accesories (keyp ads, communication modules, etc) of the old µline CAN NOT BE USED with the new CFW-08 line. As general rule, use only accessories with WEG logo, as already informed above.
This section aims at showing the differences between the old µline and the new CFW-08. The information below are addressed to user that are used to µline.
Table below shows the equivalence between the accessories of the old µline an the new CFW-08.

GENERAL INFORMATION
Expansion of the Power Range
The power range of the old µline (0.25-2HP) has been expanded to (0.25-10HP) with the new CFW-08 line.
Control Modes
Only the CFW-08 line has:
- Volt age Vector Control (VVC) that improves the inverter performance considerably - adding the parameters P178, P399, P400, P402, P403, P404, P407, P408 e P409;
- the quadratic curve V/F improves the systema energy saving capability when loads with quadratic torque x speed characteristics are driven, like pumps and fans.
Frequency Resolution
The new CFW-08 has a frequency resolution 10 times higher than the old µline, i.e., it has a resoltion of 0.01Hz for frequencies up to 100.0Hz and of 0.1Hz for frequencies higher than 99.99Hz.
Switching Frequencies of 10 and 15kHz
When the new CFW-08 is used, one can set the inverter switching frequency to 10 and 15kHz, which enables an extremly quiet operation. The audible noise level generated by the motor with 10 kHz is lower with the CFW-08, when compared with the µline. This is due to the PWM modulation improvements of the CFW-08.
Inputs and Outputs (I/Os)
The CFW-08 Plus line has more I/Os than the old µline, while the CFW-08 is equivalent to the µline in terms of of I/Os. See table below:

Parameters and Functions
Parameters that are already used in
µµ
µµ
µline but have been changed
a) P136 - Manual T orque Boost (IxR Compensation)
Besides the parameter name, also the way the user enters the IxR compensation value has been changed. In the old µline, the parameter P136 had a family of 10 curves (value range: 0 to
9). In the new CFW-08, the IxR Compensation is set by entering a percent (relating to the input voltage) that defines the output voltage for an output frequency equal to zero. So larger curve set and a larger variation range is obtained.
T able below shows the equivalence between which was programmed in the old µline and which must be programmed in the new CFW­08 to obtain the same result.

GENERAL INFORMATION
b) Automatic T orque Boost (Automatic IxR Compensation) and Slip
Compensation
In the µline only the rated motor current (P401) was used in the Automatic IxR Compensation and the Slip Compensation functions. In the µline the rated motor power factor of the motor was considered as a fixed value and equal to 0.9 . Now in the new CFW-08, are used the parameters P401 and P407 (rated motor power factor). Thus:
Example: When in an application with the µline the following setting was required: P401=3.8A, now with the new CFW-08 you must perform the following setting: P401=3.8A and P407=0.9 or P407= rated cos ∅ of the used motor and P401=3.8 x
0.9
P407
Parameters existing only in Special Software Versions of the
µµ
µµ
µline
a) Quick Inputs
In the new CFW-08, the response time of the the digital inputs is 10ms (max.). In addition, the minimum acceleration and deceleration time was reduced from 0.2s (µline) to 0.1s (CFW-08). Besides the DC braking process can be interrupted before it has been concluded, for instance, when a new enabling is required.
b) Other changes
P120=2 - digital reference backup via P121 independently of the reference source. P265=14 - DI3: multispeed using ramp #2.
New Parameters and Functions
The reference 1 of the multispeed that was in Parameter P121 (in µline) is now in Parameter P124 (in CFW-08). The DC link regulation level (ramp holding) can now be programmed in Parameter P151 - in the µline this level was fixed to 377V for the 200-240V line and 747V for the 380-480V line. Also the programming way of Parameter P302 has changed. In the µline P302 was related to the voltage applied to the output during the D Cbraking, now in the new CFW-08, P302 defines the DC Braking Current. PID regulator. Suammarizing, the new parameters are: P009, P040, P124, P151, P178, P202, P203, P205, P219, P238, P239, P240, P251, P252, P279, P399, P400, P402, P403, P404, P407, P408, P409, P520, P521, P522, P525, P526, P527 e P528.

HOW TO SPECIFY THE CFW-08 MODEL:
27
GENERAL INFORMATION
2.5 Receiving and Storing
NOTE!
The Option field (S or O) defines if the CFW-08 is a standard version or if it will be equipped with any optional devices. If the standard version is required, the specification code ends here. The model number has always the letter Z at the end. For example:
CFW080040S2024ESZ = standard 4.0A CFW-08 inverter, single-phase at 200...240V input with manual in English.
For the effect of this code, the standard product is conceived as follows:
- CFW-08 with standard control board.
- Degree of protection: NEMA 1 for the models 13 and 16A/380-480V; IP20 for the other models.
If the CFW-08 is equipped with any optional devices, you must fill out all fields in the correct sequence up to the last optional device, the model number is completed with the letter Z. It is not necessary to indicate the code number 00 for those optional devices that are standard or that will not be used.
Thus, for instance if the product above is required with NEMA 1 degree of protection: CFW080040S2024EON1Z = CFW-08 inverter, 4A, single-phase,
200...240V input, with manual in English language and with kitf fo r
NEMA 1 degree of protection. The CFW-08 Plus is formed by the inverter and the control board 1.
Example: CFW080040S2024EOA1Z.
7.0 and 16.0A/200-240V and for all 380-480V models are just available
with three-phase power supply. A RFI Class A filter (optional) can be installed inside the inverter in
models 7.3 and 10A/200-240V (single-phase) and 2.7, 4.3, 6.5, 10, 13 and 16A/380-480V . Models 1.6, 2.6 and 4.0A/200-240V (single-phase) and 1.0, 1.6, 2.6 and 4.0A/380-480V can be provided mounted on a footprint RFI Class A filter (optional).
The listing of the existing models (voltage/current) is shown in item 9.1.
The CFW-08 is supplied in cardboard boxes. The outside of the packing box has a nameplate that is identical to that on the CFW-08. Please check if the CFW-08 is the one you ordered. Check if the:
CFW-08 nameplate data matches with your purchase order . The equipment has not been damaged during transport.

CHAPTER 3
INST ALLATION
3.1 MECHANICAL INST ALLA TION
This chapter describes the procedures for the electrical and mechanical installation of the CFW-08. These guidelines and suggestions must be followed for proper CFW-08 operation.
3.1.1 Environment
The location of the inverter installation is an important factor to assure good performance and high product reliability . For proper installation, we make the following recommendations:
Avoid direct exposure to sunlight, rain, high moisture and sea air . Avoid exposure to gases or explosive or corrosive liquids; Avoid exposure to excessive vibration, dust, oil or any conductive particles or materials.
Environmental Conditions:
T emperature : 32...104ºF (0 ... 40ºC) - nominal conditions. 32...122ºF (0 ... 50ºC) - with 2% current derating for each 1.8ºF (1ºC) degree above 104ºF (40ºC). Relative Air Humidity: 5% to 90% - non-condensing. Maximum Altitude: 3,300 f t (1000m) - nominal conditions. 3,300...13,200 ft (1000 ... 4000m) - with 10% current reduction for each 3,300 ft (1000m) above 3,300 ft (1000m). Pollution Degree: 2 (according to EN50178 and UL508C)
NOTE!
When inverters are installed in panels or in closed metallic boxes, adequate cooling is required to ensure that the temperature arounds the inverter will not exceed the maximim allowed temperature. See Dissipated Power in Section 9.1.

INSTALLATION AND CONNECTION
Table 3.1 - Recommended free spaces
Install the inverter in vertical position. Leave free space around the inverter as indicated in T able 3.1. Do not install heat sensitive components immediately above the inverter. When inverters are installed side by side, maintain the minimum recommended distance B. When inverters are installed top and bottom, maintain the minimum recommended distance A + C and deflect the hot air coming from the inverter below. Install the inverter on a flat surface. External dimensions and mounting holes are according to Fig. 3.2. For CFW-08 installation procedures, see Fig. 3.3. Provide independent conduits for signal, control and power conductors. (Refer to Electrical Installation). Separate the motor cables from the other cables.
