About the CFW300
3 ABOUT THE CFW300
The CFW300 frequency inverter is a high performance product which enables speed and torque control of threephase 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 (VVW), the operation is optimized for the used motor, providing 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 those cases, it is possible to reduce the motor and inverter losses using the option "Quadratic V/f", which
results in energy saving. The V/f mode is used when more than a motor is activated by an inverter simultaneously
(multi-motor applications).
The main components of the CFW300 can be viewed in the block diagram of Figure 3.1 on page 3-1, Figure
3.2 on page 3-2 and Figure 3.3 on page 3-3. The mechanical project was designed to simplify the connection
and maintenance, as well as to ensure the safety of the product.

4.3 OPERATING MODES OF THE HMI
When inverter is powered-up, the initial state of the HMI remains in the start-up mode as long as no faults, alarms,
undervoltages occur or no keys are pressed.
The setting mode is composed of two levels: Level 1 allows browsing the parameters. Level 2 allows the modification
of the parameter selected in level 1. At the end of this level, the modified value is saved when the key is pressed.
The Figure 4.3 on page 4-2 illustrates the basic browsing of the operating modes of the HMI.

5 PROGRAMMING BASIC INSTRUCTIONS
NOTE!
The inverter comes from the factory with the frequency (V/f 50/60 Hz mode) and voltage adjusted
according to the market.
The reset to factory default may change the content of the parameters related to frequency. In the
detailed description, some parameters have values between brackets, which represents the default
value for operation in 50 Hz; thus the value without brackets is the default for operation in 60 Hz.
5.1 ACCESS AND INDICATIONS OF HMI
Whenever the inverter is powered up, the HMI display goes to the start-up mode if no faults, alarms or undervoltages
are present. In order to simplify the reading of the inverter parameters, the display was designed to show two
parameters simultaneously, at the user’s discretion. One of those parameters (main display) is shown in the numeric
form and the other parameter as a bar graph. The parameter monitored by the bar graph is selected via P207, as
indicated in Figure 5.1 on page 5-1.

Properties:
Description:
This parameter presents the inverter power supply according to identification performed after power-up.
You can use this parameter to define the inverter IGBT switching frequency.
The inverter switching frequency may be adjusted according to the application needs. Higher switching
frequencies imply less acoustic noise in the motor. However, the switching frequency choice results in a
compromise among the acoustic noise in the motor, the inverter IGBT losses and the maximum permitted
currents.
The reduction of the switching frequency reduces the effects related to the motor instability, which occurs in
certain application conditions. Besides, it reduces the earth leakage current, preventing the actuation of the
faults F070 (output overcurrent or short-circuit).
P219 - Start Point of the Switching Frequency Reduction

NOTE!
Both the function related to P219 and the function controlled by P397 (bit 3) act by reducing the
switching frequency. As the function related to P219 is intended to improve the reading of the inverter
current, that function has priority of action over the function controlled by P397 (bit 3).

Logical Command and Speed Reference
7 LOGICAL COMMAND AND FREQUENCY REFERENCE
The drive of the electric motor connected to the inverter depends on the logical command and on the reference
defined by one of the several possible sources, such as: HMI keys, digital inputs (DIx), analog inputs (AIx), Serial/
USB interface, CANopen/DeviceNet interface, SoftPLC, etc.
The command via HMI is limited to a set of functions pre-defined for the keys according to Chapter 4 HMI AND
BASIC PROGRAMMING on page 4-1, similarly to the digital inputs (DIx), with the functions implemented in
parameter P263 to P270. On the other hand, the command via digital interfaces, such as communication network
and SoftPLC, act directly on the inverter control word by means of control parameters and system markers of the
SoftPLC, respectively.
The frequency reference in turn is a numeric value in 16 bits with signal with scale in Hertz (Hz), a resolution of
0.1 Hz and full scale at 400.0 Hz.
7.1 SELECTION FOR LOGICAL COMMAND AND FREQUENCY REFERENCE
The inverter command and reference source is defined by the inverter parameters for two different situations: Local
and Remote, which can be switched dynamically during the inverter operation. Thus, for a certain parameterization,
the inverter has two sets for command and reference, according to block diagram of Figure 7.1 on page 7-2.
Parameter P220 determines the source of commands for Local and Remote situations.
Parameters P223, P224 and P225 define the commands in the Local situation; parameters P226, P227 and P228
define the commands in the Remote situation, and parameter P105 determines the source for selection between
1st and 2nd Ramp. This structure for the selection of the command source is shown in Figure 7.1 on page 7-2.
Parameters P221 and P222 define the frequency reference in the Local and Remote situations.
This structure for the selection of the reference source is shown in Figure 7.2 on page 7-3.

7.2 FREQUENCY REFERENCE
The frequency reference is the value applied to the input of the acceleration ramp module (P001) to control the
7
frequency applied to the inverter output (P002) and consequently the motor shaft speed.
Inside the CPU, the inverter uses signed 16 bit variables to treat the frequency references. Besides, the full scale of
the reference, output frequency and related variables are defined in 400.0 Hz. On the other hand, depending
on the source, this scale is conveniently modified considering the interface with the user by standardization or
application requirements.
In general, the digital references defined by parameters such as: HMI keys (P121), Multispeed (P124 to P131) and
E.P. have a scale from 0.0 to 400.0 Hz with resolution of 0.1 Hz.
In digital inputs (DIx), on the other hand, the reference is defined according to the function predefined for P263
to P266.
The frequency reference via analog inputs and frequency input is according to the signal, gain and offset parameters
P230 to P250. The full scale of the reference is always by P134, that is, maximum value in AIx is equivalent to the
frequency reference equal to P134.
The digital references Serial/USB, CANopen, DeviceNet, Profibus DP and SoftPLC act on a standardized
scale called "13-bit speed", where the value 8192 (213) is equivalent to the motor rated frequency (P403). Those
references are accessed by parameters P683 and P685.
The digital references, though, have a different scale and the frequency reference parameters with their range from
0.0 to 400.0 Hz, according to previous descriptions. The frequency value on the ramp input (P001) is always limited
by P133 and P134. For example, the JOG reference is given by P122, this parameter may be set in up to 400.0 Hz,
but the value applied to the ramp input as reference will be limited by P134 when the function is executed.

7.2.1 Limits for Frequency Reference
Although the parameters to adjust the reference have a wide range of values (0 to 400.0 Hz), the value applied
to the ramp is limited by P133 and P134. Therefore, the values in module out of this range will have no effect on
the reference.

Description:
This parameter defines the operation of the backup function of the speed reference from one of the options
active (P120 = 1), inactive (P120 = 0) and by P121 (P120 = 2). This function, in turn, determines the form of
backup of the digital references of the sources: HMI (P121), E.P., Serial/USB (P683), according to Table 7.2 on
page 7-7.

0Value of P133
1Last adjusted value
2Value of P121
If P120 = Inactive, the inverter will not save the speed reference value when it is disabled. Thus, when the
inverter is enabled again, the speed reference value will become the frequency minimum limit value (P133).
If P120 = Active, the value set in the reference is not lost when the inverter is disabled or powered down.
If P120 = Backup by P121, the reference initial value is fixed by P121 at the enabling or power-up of the inverter.

The Electronic Potentiometer function (E.P.) allows the frequency reference to be set by means of two digital inputs
(one to increment it and another to decrement it).
In order to enable this function, you must first configure the referency reference via E.P., program P221 = 7 and/or
P222 = 7. After enabling this function, just program two digital inputs (P263 to P266) in 11 or 33 (Accelerate E.P.)
and 12 or 34 (Decelerate E.P.).
Figure 7.4 on page 7-11 shows the operation of E.P. function of three digital inputs (Accelerate E.P., Decelerate
E.P. and Run/Stop). In this example, the reference reset is done with the inverter disabled and activating both
Accelerate and Decelerate E.P. inputs. Besides, you can monitor the action of the inputs individually, as well as
the action of the reference backup (P120 = 1) when the Run/Stop command is opened and closed again.

the reference described in Section 7.1 SELECTION FOR LOGICAL COMMAND AND FREQUENCY REFERENCE
on page 7-1.
7.2.6 "13-Bit Speed" Reference
The 13-bit Frequency Reference is a scale based on the motor rated speed (P402) or on the motor rated frequency
(P403). In the CFW300, parameter P403 is taken as the base to determine the frequency reference.
Thus, the 13-bit frequency value has a range of 16 bits with signal, that is, -32768 to 32767; however, the rated
frequency in P403 is equivalent to the value 8192. Therefore, the maximum value in the range 32767 is equivalent
to four times P403.
The 13-bit frequency reference is used in parameters P681 and P683, which are related to the interfaces with
communication (Serial/USB, CANopen, DeviceNet and Profibus DP) of the product.
7.3 CONTROL WORD AND INVERTER STATUS
The inverter control word is the grouping of a set of bits to determine the commands received by the inverter from
an external source. On the other hand, the status word is another set of bits that define the inverter status. This
way, the control and status words establish an interface for the exchanging of information between the inverter
and an external module, such as a communication network or a controller.

This parameter is applied to all the inverter command sources, but it was created aiming at allowing
the command via HMI to be able to disable the motor by inertia instead of deceleration ramp. In this
way, when P229 = 1, Bit 0 of the control word (Ramp Enable) has a function similar to Bit 1 (General
Enable). The same way, the digital input functions such as: Run/Stop, Forward/Reverse Run stop
the motor by inertia in this condition of P229.

Available Motor Control Types
8 AVAILABLE MOTOR CONTROL TYPES
The inverter feeds the motor with variable voltage, current and frequency, providing control of the motor speed.
The values applied to the motor follow a control strategy, which depends on the selected type of motor control
and on the inverter parameter settings.
The selection of the proper control type for the application depends on the static and dynamic requirements of
torque and speed of the driven load, that is, the control type is directly connected to the required performance.
Additionally, proper configuration of the selected control mode parameters is essential to reach maximum
performance.
The CFW300 is equipped with three control modes for the three-phase induction motor, that is:
V/f Scalar Control: for basic applications without output speed control.
Quadratic V/f Scalar Control: for applications that reduce motor and inverter losses without regulation of
the output speed.
VV W Sensorless Vector Control: for applications that need high performance in the control of the output
speed.
In Chapter 9 V/f SCALAR CONTROL on page 9-1 and Chapter 10 VVW VECTOR CONTROL on page 10-1,
each of these kinds of control, related parameters and directions regarding the use of each of these modes are
described in details.

Setting:
cfg
000Bh
Description:
The bits of parameter P397, as shown in Table 8.1 on page 8-2, enable a series of internal options to configure
the control of the induction motor, such as:
Slip Compensation during the Regeneration (Bit 0)
The regeneration is an operating mode of the inverter which occurs when the power flux goes from the motor
to the inverter. The bit 0 of P397 (set in 0) allows the slip compensation to be turned off in this situation. This
option is particularly useful when the compensation during the motor deceleration is necessary.
Output Current Stabilization (Bit 2)
High-performance motors with power above 5 HP are marginally stable when driven by frequency inverters
and at operation with no load. Therefore, in this situation a resonance may occur in the output current which
may reach the overcurrent level F070. Bit 2 of P397 (set to 1) activates an algorithm for regulation of the
output current in closed loop which neutralizes the oscillations of resonant output current.
Reduction of P297 at high temperature (Bit 3)
Bit 3 of P397 controls the overtemperature protection action according to section Section 14.2 IGBTS
OVERLOAD PROTECTION (F051 AND A050) on page 14-3.
8
NOTE!
Both the function related to P219 and the function controlled by P397 (bit 3) act by reducing the
switching frequency. As the function related to P219 is intended to improve the reading of the inverter
current, that function has priority of action over the function controlled by P397 (bit 3).
ATTENTION!
The default setting of P397 meets most application needs of the inverter.
Therefore, avoid modifying its content without knowing the related consequences. If you are not
sure, contact WEG Technical Assistance before changing P397.
Table 8.1: Options available to configure the control (P397)
This is the classical control method for three-phase induction motors, based on a curve that relates output
frequency and voltage. The inverter works as a variable frequency and voltage source, generating a combination
of voltage and frequency according to the configured curve. It is possible to adjust this curve for standard 50 Hz,
60 Hz or special motors.
According to the block diagram of Figure 9.1 on page 9-2, the frequency reference f* is limited by P133 and P134
and applied to the input of "V/f Curve" block, where the output voltage amplitude and frequency imposed to the
motor are obtained. For further details on the frequency reference, refer to Chapter 7 LOGICAL COMMAND AND
FREQUENCY REFERENCE on page 7-1.
By monitoring the total and active output current, and the DC link voltage, compensators and regulators are
implanted so as to help in the protection and performance of the V/f control. The operation and parameterization of
those blocks are detailed in Section 11.2 DC LINK VOLTAGE AND OUTPUT CURRENT LIMITATION on page 11-3.
The advantage of the V/f control is its simplicity and the need of few settings. The start-up is quick and simple
and the factory default, in general, requires little or no modification. In cases whose objective is to reduce losses
on the motor and inverter, the "Quadratic V/f" may be used, where the flow in the motor air-gap is proportional to
the output frequency up to the field weakening point (also defined by P142 and P145). Thus, the result is a torque
capacity as a quadratic function of the frequency. The great advantage of such control is the capacity to save
energy when driving loads with variable resistant torque, due to the reduction of motor losses (especially losses
in the air-gar, magnetic losses).
The V/f or scalar control is recommended for the following cases:
Drive of several motors with the same inverter (multi-motor drive).
Energy saving in the drive of loads with quadratic torque/frequency relationship.
Motor rated current lower than 1/3 of the inverter rated current.
For test purposes, the inverter is turned on without motor or with a small motor with no load.
Applications where the load connected to the inverter is not a three-phase induction motor.
Applications that aim at reducing losses on the motor and inverter (Quadratic V/f).

V/f Scalar Control
9.1 PARAMETERIZATION OF THE V/f SCALAR CONTROL
The scalar control is the inverter factory default control mode for its popularity and because it meets most
applications of the market. However, parameter P202 allows the selection of other options for the control mode,
as per Chapter 8 AVAILABLE MOTOR CONTROL TYPES on page 8-1.
The V/f curve is completely adjustable in four different points as shown in Figure 9.2 on page 9-3, although the
factory default set a curve pre-adjusted for motors 50 Hz or 60 Hz, as options for P204. This format, point P0
defines the amplitude applied at 0 Hz, while P2 defines the rated amplitude and frequency and beginning of field
weakening. Intermediate points P1 allow the setting of the curve for a non-linear relationship between torque and
frequency, for instance, in fans where the load torque is quadratic in relation to the frequency. The field weakening
region is determined between P2 and P3, where the amplitude is maintained in 100 %.

The factory default setting of the CFW300 defines a linear relation of the torque with the frequency by means of
three points (P0, P1 and P2).
The points P0[P136, 0 Hz], P1[P143, P146], P2[P142, P145] and P3[100 %, P134] can be set so that the voltage and
frequency relation imposed to the output approximates the ideal curve for the load. Therefore, for loads in which
the torque behavior is quadratic in relation to the frequency, such as in centrifugal pumps and fans, the points
of the curve can be set or the Quadratic V/f control mode can be used so as to save energy. This Quadratic V/f
curve is presented in Figure 9.3 on page 9-3.

constant.
The optimum setting is the smallest value of P136 which allows the motor satisfactory start. A value greater
than necessary will excessively increase the motor current at low speeds, which may lead the inverter to a fault
condition (F051 or F070) or alarm condition (A046 or A050), as well as motor overheating. Figure 9.4 on page

increments the output frequency (Δf) considering the increase of the motor active current, as shown in Figure
9.7 on page 9-6. In Figure 9.1 on page 9-2 this compensation is represented in the variable f
The setting in P138 allows regulating with good accuracy the slip compensation by moving the operation
point on the V/f curve, as shown in Figure 9.7 on page 9-6. Once P138 is set, the inverter is able to keep the
frequency constant even with load variations.

Sequence for installation, verification, power up and start-up.
1. Install the inverter: according to chapter 3 Installation and Connection of the user’s manual, making all the
power and control connections.
2. Prepare and power up the inverter according to section 3.2 Electrical Installation of the user’s manual of the
CFW300.
3. Load the factory default with P204 = 5 (60 Hz) or P204 = 6 (50 Hz), according to the input rated frequency
(power supply) of the inverter used.
4. In order to set a V/f curve different from the default, set the V/f curve using parameters P136 to P146.
5. Setting of specific parameters and functions for the application: program the digital and analog inputs and
outputs, HMI keys, etc., according to the application requirements.
9.3 ENERGY SAVING
The efficiency of a machine is defined as being the ratio between the output mechanical power and the input
electrical power. Remember that the mechanical power is the product between torque and rotor speed, and that
the input electric power is the sum of the output mechanical power and the motor losses.
In the case of the three-phase induction motor, the optimized efficiency is achieved with ¾ of the rated load. In
the region below this point, the Energy Saving function has its best performance.
The Energy Saving function acts directly on the voltage applied on the inverter output; thus, the flux relationship
delivered to the motor is changed so as to reduce the motor losses and enhance the efficiency, consequently
reducing consumption and noise.

The function will be active when the motor load is below the maximum value (P588) and the frequency is above

a minimum acceptable value (P589). The parameter group presented in the sequence defines the characteristics
necessary for the energy saving function.

V VW Vector Control
10 VVW VECTOR CONTROL
The V VW vector control mode (Voltage Vector WEG) uses a control method with a much higher performance
than the V/f control because of the load torque estimation and of the control of the magnetic flux in the air gap, as
per scheme of Figure 10.1 on page 10-2. In this control strategy, losses, efficiency, rated slip and power factor of
the motor are considered in order to improve the control performance.
The main advantage compared to the V/f control is the best frequency regulation with greater torque capacity at
low speeds (frequencies below 5 Hz), allowing a relevant improvement in the drive performance in permanent
duty. Besides, the V VW control has a quick and simple setting and it is suitable for most medium-performance
applications in the control of three-phase induction motor.
By just measuring the output current, the VV W control instantly obtains the motor torque and slip. Thus, the
VV W actuates in the output voltage compensation and slip compensation. Therefore, the VV W controller action
replaces the classical V/f functions in P137 and P138, but with a calculation model much more sophisticated and
accurate, meeting several load conditions or operation points of the application.
In order to achieve a good frequency regulation in permanent duty with a good operation of the V VW control, the
parameter setting in the range P399 to P407, and the stator resistance in P409 are essential for the good operation
of the VV W control. These parameters can be easily obtained on the motor nameplate.

V VW Vector Control
10 .1 VVW VECTOR CONTROL PARAMETERIZATION
The V VW control mode is selected by parameter P202, control mode selection, as described in Chapter 8
AVAILABLE MOTOR CONTROL TYPES on page 8-1.
Opposite to the V/f scalar control, the VV W control requires a series of data from the motor nameplate and a
self-tuning for its proper operation. Besides, it is recommended that the driven motor match the inverter, that is,
the motor and inverter power be as close as possible.
Below are described the parameters to configure the V VW vector control setting. This data is easily obtained on
WEG standard motor nameplates, however in older motors or motors made by other manufacturers, the data
may not be readily available. In those cases, it is recommended first contact the motor manufacturer, measure or
calculate the desired parameter. As a last resort, the user always can make a relationship with Table 10.1 on page
10-3 and use the equivalent or approximate WEG standard motor parameter.
NOTE!
The correct setting of the parameters directly contributes to the V VW control performance.

During the self-tuning, the bar graph shows the progress of the operation and the motor remains still, because
a DC signal is sent to measure the stator resistance.
If the estimated value of the motor stator resistance is too high for the inverter used (for example: motor not

10.2 START-UP IN V VW MODE
NOTE!
Read chapter 3 Installation and Connection of the user’s manual before installing, powering up or
operating the inverter.
Sequence for installation, verification, power up and start-up:
1. Install the inverter: according to chapter 3 Installation and Connection of the user’s manual, making all the
power and control connections.
2. Prepare and power up the inverter: according to section 3.2 Electrical Installation of the user’s manual.
3. Load the correct factory default in P204: based on the motor rated frequency (set P204 = 5 for 60 Hz
motors and P204 = 6 for 50 Hz motors).
4. Adjustment of parameters and specific functions for the application: program the digital and analog
inputs and outputs, HMI keys, etc., according to the application requirements.
5. Activation of the V VW control: set P202 = 5 and parameters P399, P400, P401, P402, P403, P404 and
P407 according to the motor nameplate. Also set the value of P409. If some of those data are not available,
enter the approximate value by calculation or by similarity with WEG standard motor - see Table 10.1 on page
10-3.
6. Self-Tuning of the V V W control: the self-tuning is activated by setting P408 = 1. In this process, the inverter
applies DC to the motor to measure the stator resistance, while the HMI bar graph shows the progress of the
self-tuning. The self-tuning process can be interrupted at any time by pressing the key.

7. End of the Self-Tuning: at end of the self-tuning, the HMI returns to the browsing menu, the bar displays the
parameter programmed by P207 again and the stator resistance measured is stored in P409. On the other
hand, if the self-tuning fails, the inverter will indicate a fault. The most common fault in this case is F033, which
indicates error in the estimated stator resistance. Refer to Chapter 14 FAULTS AND ALARMS on page 14-1.

Functions Common to All the Control Modes
11 FUNCTIONS COMMON TO ALL THE CONTROL MODES
This chapter describes the functions common to the inverter V/f and VV W control modes, but which interferes
in the drive performance.
11.1 RAMPS
The inverter ramp functions allow the motor to accelerate or decelerate faster or slower. They are adjusted by
parameters that define the linear acceleration time between zero and the maximum frequency (P134) and the time
for a linear deceleration from the maximum frequency zero.
In the CFW300, three ramps with different functions were implemented:
st
1
Ramp - standard for most functions.
nd
2
Ramp - it may be activated by the user, according to the drive requirement, by means of the inverter
command word or by a digital input.
Emergency Ramp - it is used for the inverter internal protection functions, such as: current limitation, DC link
regulation, etc. The Emergency Ramp has priority over the other ramps.
NOTE!
The setting with too short ramp time may cause overcurrent in the output (F070), undervoltage (F021)
or overvoltage (F022) of the DC link.

Properties:
Description:
This parameter allows the inverter acceleration and deceleration ramps to have a non-linear profile, similar to an
"S", aiming at reducing the mechanical shocks on the load, as shown in Figure 11.1 on page 11-2.
It defines the origin source of the command to select between the first and second Ramp.
Note: Parameter P680 (Logical Status) indicates if the 2nd Ramp is active or not. For further information on this
parameter, refer to Section 7.3 CONTROL WORD AND INVERTER STATUS on page 7-11.
11. 2 DC LINK VOLTAGE AND OUTPUT CURRENT LIMITATION
The DC link voltage and output current limitation are protection functions of the inverter which act on the ramp
control, aiming at containing the rise of voltage on the DC link and of the output current. In this way, the following of
the reference by the ramp is blocked and the output frequency follows the Emergency Ramp for a preset safety
value.
When the DC link voltage is too high, the inverter may freeze the deceleration ramp. On the other hand, when
the output current is too high, the inverter may decelerate or freeze the acceleration ramp in order to reduce this
current. Those actions prevent the occurrence of faults F022 and F070, respectively.
Both protections normally occur at different moments of the inverter operation, but in case of occurrence at the
same time, by definition, the DC link limitation has higher priority than the output current limitation.
The voltage limitation on the DC link during braking actuates limiting the braking power and torque, so as to prevent
the shutting down of the inverter for overvoltage (F022). This situation often occurs when a load with high moment
of inertia is decelerated or when short deceleration time is programmed.
11. 2 .1 DC Link Voltage Limitation by "Ramp Hold" P150 = 0 or 2
It has effect during deceleration only.
Actuation: when the DC link voltage reaches the level set in P151, a command is sent to the "ramp" block, which
inhibits the motor frequency variation according to Figure 9.1 on page 9-2 and Figure 10.1 on page 10-2.
Use recommended in the drive of loads with high moment of inertia referred to the motor shaft or loads that
require short deceleration ramps.
11.2.2 DC Link Voltage Limitation by "Accelerate Ramp" P150 = 1 or 3
It has effect in any situation, regardless the motor frequency condition: accelerating, decelerating or constant
frequency.
Actuation: when the DC link voltage reaches the level set in P151, a command is sent to the "ramp" block to
accelerate the motor.
11
Use recommended for the drive of loads that require braking torques at constant frequency in the inverter
output. For example, the drive of loads with eccentric shaft as in sucker rod pumps; another application is the
handling of loads with balance like in the translation in overhead cranes.

Figure 11.4: Example graph of the DC Link voltage limitation - Accelerate Ramp
Like in the DC Link voltage regulation, the output current regulation also has two operating modes: "Ramp Holding"
(P150 = 2 or 3) and "Decelerate Ramp" (P150 = 0 or 1). Both actuate limiting the torque and power delivered to the
motor, so as to prevent the shutting down of the inverter by overcurrent (F070). This situation often occurs when
a load with high moment of inertia is accelerated or when short acceleration time is programmed.
11. 2 .3 Output Current Limitation by "Ramp Hold" P150 = 2 or 3
It prevents the motor from collapsing during torque overload in the acceleration or deceleration.
Actuation: if the motor current exceeds the value set in P135 during acceleration or deceleration, the frequency
will not be incremented (acceleration) or decremented (deceleration). When the motor current reaches a value
below P135 the motor accelerates or decelerates again. Refer to Figure 11.5 on page 11-6.

forcing the motor deceleration. When the motor current reaches a value below P135 the motor accelerates
again. Look at Figure 11.5 on page 11-6.

11. 3 FLYING START / RIDE-THROUGH
The Flying Start function allows driving a motor that is in free running, accelerating it from the rotation in which it
is. The Ride-Through function allows recovering the inverter, with no locking by undervoltage, when there is an
instant drop in the power supply.
Both functions assume the special case in which the motor is running in the same direction and at a frequency
close to the frequency reference, thus, by immediately applying the frequency reference to the output and increasing
the output voltage in ramp, the slip and the starting torque are minimized.

Description:
Parameter P332 sets the minimum time the VSD will wait until driving the motor again with the Ride Through
function, which is necessary to demagnetize the motor.
11. 3.1 Flying Start Function
In order to activate this function, just program P320 in 1 or 2; thus the inverter will impose a fixed frequency at
the start, defined by the frequency reference, and apply the voltage ramp defined in parameter P331. In this way,
the start current is reduced. On the other hand, if the motor is at rest, the frequency reference and the real frequency
of the motor are very different or the direction of rotation is inverted; the result in such cases may be worse than the
conventional start without Flying Start.
The Flying Start function is applied on loads with high inertia or systems that require start with the motor
spinning. Besides, the function may be deactivated dynamically by a digital input P263 to P266 programmed
for "24 = Disable Flying Start". In this way, the user may activate the function in a convenient way according to
the application.

11. 3. 2 Ride-Through Function
The Ride-Through function will disable the inverter output pulses (IGBT) as soon as the supply voltage reaches a
value below the undervoltage value. A fault due to undervoltage (F021) does not occur and the DC link voltage will
slowly drop until the supply voltage returns. In case it takes the supply voltage too long to return (over 2 seconds),
the inverter may indicate F021 (undervoltage on the DC link). If the supply voltage returns before, the inverter will
enable the pulses again, imposing the frequency reference instantly (like in the Flying Start function) and making a
voltage ramp with time defined by parameter P331. Refer to Figure 11.6 on page 11-8.

The Ride-Through function allows recovering the inverter without locking by undervoltage F021 for momentary
power supply drops. The time interval accepted during a fault is at most two seconds.
11. 4 DC BRAKING
The DC Braking allows stopping the motor by applying direct current to it. The current applied at the DC Braking
is proportional to the braking torque and may be set in P302. It is set in percentage (%) of the inverter rated current
considering the motor of power compatible with the inverter.

P302 - Voltage Applied to the DC Braking
Adjustable
Range:
Properties:
Description:
This parameter sets the DC voltage (DC Braking torque) applied to the motor during the braking.
The setting must be done by gradually increasing the value of P302, which varies from 0.0 to 100.0 % of the
rated braking voltage, until the desired braking is obtained.
The rated braking voltage is the DC voltage value, which results in the rated current for the motor with power
matched to the inverter. Therefore, if the inverter has a power too much higher than the motor, the braking
torque will be too low. On the other hand, if the opposite is true, overcurrent may occur during the braking, as
well as overheating of the motor.

11.6 FIRE MODE
The “Fire Mode” function is intended to make the frequency inverter continue to drive the motor even under
adverse conditions, inhibiting most faults generated by the frequency inverter. The “Fire Mode” is activated by
driving a digital input previously set to “Fire Mode” with logic level “0” at the input terminals. When the drive enters
the“Fire Mode”, the alarm “A211” will be generated on the HMI (keypad) and the status of the operation mode will
be updated in parameter P006.
DANGER!
“FIRE MODE” FUNCTION – RISK OF DEATH!
Notice that the CFW300 is only one of the components of the system, and it is configurable for
several functions that must be pre-established in the project.
Therefore, the full operation of the "Fire Mode" function, with the required safety, depends on the
specification in the project, as it also requires the compatibility with all the other components of
the system and the installation environment.
Ventilation systems that operate in life safety applications must be approved by the Fire Department
and/or another competent local public authority.
The activation of the “Fire Mode” function disables essential protection functions for the safety of
the CFW300 and of the system as a whole.
The non-interruption of the CFW300 operation due to the improper activation of the “Fire Mode”
function is critical, as it may cause injuries or even death, and damages to the CFW300, to the
other components of the system and to the environment where it is installed.
The operation in the “Fire Mode” function may, under certain circumstances, result in fire, as the
protection devices will be disabled.
Only qualified personnel from safety engineer departments must evaluate and activate the
equipment “Fire Mode” function.
It is essential to follow the aforementioned instructions before using the CFW300 in the "Fire
Mode" function.
Under no circumstance shall WEG take any liability for deaths, damages, compensations and/or losses
occurred due to the improper programming or operation of the CFW300 in the "Fire Mode" function.
IMPORTANT – RISK OF DEATH!
When activating the “Fire Mode” function, the user must be aware of the fact that the protection
functions of the CFW300 will be disabled, which may result in damages:
- To the inverter.
- To the components connected to it.
- To the environment where it is installed.
- To the people present in the place.
Therefore, the operator who activates the “Fire Mode” function takes full liability for the resulting risks.
The operation of the inverter with the “Fire Mode” function programmed voids the warranty of the
product.
The operation in this condition is internally registered by the CFW300, and it may be validated by an
engineer and occupational safety professional duly qualified by the manufacturer.

CFW300 | 11-11
Functions Common to All the Control Modes
NOTE!
When activating the "Fire Mode" function, the user acknowledges that the protection functions of the
CFW300 are disabled, which may result in damages to the CFW300, to the components connected
to it, to the environment in which it is installed and to the people present in such environment.
Therefore, the user takes full liability for the resulting risks. The operation of the inverter with the “Fire
Mode” function enabled voids the warranty of the product. The operation under such condition is
internally registered by the CFW300 and must be validated by an engineer and occupational safety
professional duly qualified.
If the user presses the P key, the message will disappear from the display (A211), but the operation
mode will continue to be shown in parameter P0006. It is also possible to indicate this condition in
a digital output (DOx) previously programmed for “Fire Mode”. During the operation in “Fire Mode”,
all the stop commands are ignored (even General Enable).
Some Faults (considered critical) that may damage the CFW300 will not be disabled, but they can
be infinitely reset automatically (define this condition in parameter P582): Overvoltage on the DC Link
(F022), Overcurrent/Short Circuit (F070).
