About the CFW501
3 ABOUT THE CFW501
The frequency inverter CFW501 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 (VV W) or scalar (V/f) control,
both programmable according to the application.
In the vector mode, the operation is optimized for the used motor, providing a better performance in terms of speed
control torque. The “Self-Tuning” function, available for the vector control, allows the automatic setting of control
parameters and controllers based on the identification (also automatic) of the motor parameters.
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 by adjusting the V/f curve using the parameters
based on quadratic curve approximation of the V/f relationship, which results in energy saving. The V/f mode is
used when more than a motor is activated by an inverter simultaneously (multimotor applications).
The main components of the CFW501 can be viewed in the block diagram of Figure 3.1: CFW501 block diagram
on page 3-2 and Figure 3.2: Main components of the CFW501 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.
Developed to meet the main technological requirements of the market, the CFW501 has a plug-in modular interface
which adapts to the application. As shown in item 4 of Figure 3.2: Main components of the CFW501 on page
3-3, the plug-in allows the CFW501 to meet the requirements of different applications.
All CFW501 interface models feature communication in physical media RS485 with Modbus RTU and resources
for data transfer via memory card.

on the secondary display. Such fields of the display are defined in Figure 4.2: Display areas on page 4-2.
Level 1 allows the user to select the menu items to direct the browsing of the parameters.
Level 2 allows browsing the parameters of the group selected by level 1.
Level 3, in turn, allows the modification of the parameter selected in level 2. At the end of this level, the modified
value is saved or not if the key ENTER or ESC is pressed, respectively.
The Figure 4.3: HMI operating modes on page 4-3 illustrates the basic browsing of the operating modes of the HMI.
Monitoring Mode
It is the initial status of the HMI af ter the powering up and of the initialization
screen, with factory default values.
The field menu is not active in this mode. The main display and secondary display of the HMI indicate the values of
the two parameters preset by P0205 and P0206.
From the monitoring mode, when you press the ENTER/MENU key, you
commute to the setting mode.
Setting Mode
Level 1:
This is the first level of the setting mode. It is possible to choose the
parameter group using the keys and .
The fields: main display, secondary display, bar graph for monitoring of
variable and measurement units are not shown in this level.
Press the ENTER/MENU key to go to level 2 of the setting mode – parameter
selection.
Press the BACK /ESC key to return to the monitoring mode.
Level 2:
The number of the parameter is shown on the main display and its content
on the secondary display.
Use the and keys to find the desired parameter. Press the ENTER/MENU key to go to level 3 of the set ting mode- modification
of the parameter content.
Press the BACK /ESC key to return to level 1 of the setting mode.
Level 3:
The content of the parameter is shown on the main display and the number
of the parameter is shown on the secondary display.
Use the and keys to configure the new value for the selected
parameter.
Press the ENTER/MENU key to confirm the modification (save the new
value) or BACK/ESC to cancel the modification (not save the new value).
In both cases, the HMI returns to level 2 of the setting mode.

5.1 PARAMETER STRUCTURE
Aiming at simplifying the parameterization process, the CFW501 parameters were classified into ten groups which
can be individually selected in the Menu area of the HMI display. When the enter/menu key of the HMI is pressed in
the monitoring mode, you enter the setting mode level 1. In this mode, it is possible to select the desired parameter
group by browsing with the "" and "" keys. For further details on the use of the HMI, refer to chapter 4 HMI
AND BASIC PROGRAMMING on page 4-1.
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 as per
P0204. 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.
5.2 PARAMETERS SELECTED BY THE HMI MENU

In the first level of the setting mode, select the group to browse the next levels according to the table below.
Table 5.1: Parameter group accessed by the HMI MENU
GroupContained Parameters
PARAMAll parameters.
Read only parameters:
READ
MODIFOnly parameters whose contents are different from the factor y settings.
Besides the selected group in the menu field of the HMI, the view of the parameters on the HMI
depends on the hardware installed and on the operating mode of the CFW501. Therefore, observe
the connected plug-In module, as well as the motor control mode: V VW or V/f. For example, if the
plug-in module only features the analog input AI1, the parameters related to the other analog inputs
are not shown. The same occurs with the parameters exclusively related to the V VW and V/f modes.
5.3 HMI
In the HMI group, you find parameters related to the showing of information on the display, backlight and password
of the HMI. See detailed description below of the possible settings of the parameters.

After setting P0000 with a password value, P0000 will show “1” or “0”, keeping the set password value hidden.
Where “1” releases the access to parameters and “0” locks the access to the parameters.
NOTE!
The access to the parameters and P0000 is cleared together with the powering down of the inverter.

6 IDENTIFICATION OF THE INVERTER MODEL AND ACCESSORIES
To verify the inverter model, check the code on the product identification labels: the complete one, on the side of
the inverter, or the summarized one, under the HMI.
Once the inverter model identification code is checked, it is necessary to interpret it in order to understand its
meaning. Refer to chapter 2 - General Information of the CFW501 user’s manual.
Below are the parameters related to the inverter model which change according to the inverter model and version.
Those parameters must comply with the data read on the product identification label.

Description:
You can use this parameter to define the inverter IGBT switching frequency.
The inverter switching frequency may be adjusted according to the appliction 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 F0074 (earth fault) or F0070 (output overcurrent or short-circuit).
ATTENTION!
Check the output current data considering the switching frequency when it is different from the
default in table B.4 available in annex B - Technical Specifications of the CFW501 user's manual.

Logical Command and Speed Reference
7 LOGICAL COMMAND AND SPEED 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, 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 P0263 to P0270.
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 speed reference, in turn, is processed inside the CFW501 in 16 bits with signal (-32768 to +32767) for
a range from -18000 rpm to 18000 rpm and, therefore, minimum resolution of 0.55 rpm. On the other hand,
the unit factor, range and resolution of the reference depend on the used source, as described in section 7.2
SPEED REFERENCE on page 7-7.
7.1 SELECTION FOR LOGICAL COMMAND AND SPEED 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: General block
diagram for commands and references on page 7-2.
7
Parameter P0220 determines the source of commands between the Local and Remote situations.
Parameters P0223, P0224 and P0225 define the commands in the Local situation; parameters P0226, P0227 and
P0228 define the commands in the Remote situation, and parameter P0105 determines the source for selection
between 1st and 2nd ramp. This structure for the selection of the command source is shown in Figure 7.2: Command
selection structure on page 7-3, where parameter P0312 directs the serial communication source for the plug-in
modules with two ports.
Parameters P0221 and P0222 define the speed reference in the Local and Remote situations, respectively. This
structure for the selection of the reference source is shown in Figure 7.3: Structure to select the speed reference on
page 7-4, where parameter P0312 directs the serial communication source to the plug-in modules with two ports.

7.2 SPEED REFERENCE
The speed reference is the value applied to the input of the acceleration ramp module (P0001) to control the
frequency control applied to the inverter output (P0002) and consequently the motor shaft speed.
Internally, the inverter CPU uses 16-bit variables with signal to treat the speed references. Besides, the full scale
of the reference, output frequency and related variables is defined in 1800 rpm. On the other hand, depending
on the source, this scale is conveniently modified considering the interface with the user by standardization or
application requirements.
7
In general, the digital references defined by parameters such as: HMI keys (P0121), and JOG have a scale from 0
to 18000 rpm with resolution of 1 rpm. On the other hand, the reference via analog input uses the 16-bit internal
scale with signal with a full scale in 18000 rpm and resolution of 0.55 rpm.
The speed reference via HMI can be the JOG key of the keys "" and "" on parameter P0121.
In digital inputs (DIx), on the other hand, the reference is defined according to the function predefined for P0263
to P0270.
The speed reference via analog inputs and frequency input is according to the signal, gain and offset parameters
P0230 to P0250. The full scale of the reference is always by P0134, that is, maximum value in AIx is equivalent to
the speed reference equal to P0134.
The digital references Serial/USB and SoftPLC act on a standardized scale called “13-bit Speed”, where the
value 8192 (213) is equivalent to the motor rated frequency given by P0403. Those references are accessed by
parameter P0683 and system marker of the SoftPLC, respectively.
Although the digital references have a different scale and speed reference parameters with their range from 0 to
18000 rpm, as previously informed, the speed value on the ramp input (P0001) is always limited by P0133 and
P0134. For example, the JOG reference is given by P0122; this parameter may be set to up to 18000 rpm, but
the value applied to the ramp input as reference will be limited by P0134 when the function is executed.

Although the parameters to adjust the reference have a wide range of values (0 to 18000), the value applied to

digital references and sources: HMI (P0121), Serial/USB (P0683) and SoftPLC according to Table 7.2: Options

If P0120 = 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 speed minimum limit value (P0133).
If P0120 = Active, the value set in the reference is not lost when the inverter is disabled or powered down.
If P0120 = Backup by P0121, the reference Initial value is fixed by P0121 at the enabling or power-up of the
inverter.

The behaviors of the analog and frequency inputs are described in details in section 12.1 ANALOG INPUTS on
page 12-1. Thus, after the proper signal treatment, it is applied to the ramp input according to the section 7.1
SELECTION FOR LOGICAL COMMAND AND SPEED REFERENCE on page 7-1.
7.2 .5 13-Bit Speed Reference
The 13-bit speed reference is a scale based on the motor rated speed (P0403). In the CFW501, parameter
P0403 is taken as the base to determine the speed reference. Thus, the 13-bit speed value has a range of 16
bits with signal, that is, -32768 to 32767; however, the rated frequency in P0403 is equivalent to the value 8192.
Therefore, the maximum value in the range 32767 is equivalent to four times P0403.
The 13-bit speed reference is used in parameters P0681 or P0685 and system marker for the SoftPLC, which
are related to the interfaces with communication networks and SoftPLC function of the product.

NOTE!
This parameter is applied to all the inverter command sources, but it was created aiming at allowing
the command P0229 via HMI to be able to disable the motor by inertia instead of deceleration ramp.
In this way, when P0229 = 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
and command with three wires turn off the motor by inertia in this condition of P0229.
7.3 .1 Control via HMI Inputs
Contrary to the network interfaces and SoftPLC, the HMI commands do not access the inverter control word

7.3 . 2 Control via Digital Inputs
Contrary to the network interfaces and SoftPLC, the digital inputs do not access the inverter control word directly,

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.
Besides, the setting of the parameters involved is essential to reach such performance.
The CFW501 is equipped with two control modes for the three-phase induction motor, that are:
V/f Scalar Control: for basic applications without output speed control. 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.

P0397 – Control Configuration
Adjustable
Range:
Properties:cfg
Description:
The bits of parameter P0397, as shown in Table 8.1: Options available to configure the control (P0397) on page
8-3, 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 P0397 (set in 0) allows the slip compensation to be turned off in this situation. This option is
8
particularly useful when the compensation during the motor deceleration is necessary.
0000h to 000FhFactory
Setting:
000Bh
Dead Time Compensation (Bit 1)
The dead time is a time interval introduced in the PWM necessary for the commutation of the power inverter
bridge. On the other hand, the dead time generates distortions applied to the motor, which can cause torque
reduction at low speeds and current oscillation in motors above 5 HP running with no load. Thus, the dead time
compensation measures the voltage pulse width in the output and compensates this distortion introduced by
the dead time.
Bit 1 of P0397 (set in 0) allows deactivating this compensation. This feature is useful when there is a problem
related to the inverter internal circuit for pulse feedback causing fault F0182. Thus, the compensation, and
consequently the fault, can be disabled.
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 F0070. Bit 2 of P0397 (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 P0297 at high temperature (Bit 3)
Bit 3 of P0397 controls the overtemperature protection action according to section 14.4 IGBTS
OVERTEMPERATURE PROTECTION (F0051 AND A0050) on page 14-6.
ATTENTION!
The default setting of P0397 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 P0397.

Available Motor Control Types
Table 8 .1: Options available to configure the control (P0397)
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 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 or
60 HZ or special motors.
According to the block diagram of Figure 9.1: Block diagram of V/f scale control on page 9-2, the speed reference
f* is limited by P0133 and P0134 and applied to the input of “V/f CURVE” block input, where the output voltage
amplitude and frequency imposed to the motor are obtained. For further details on the speed reference, refer to
chapter 7 LOGICAL COMMAND AND SPEED REFERENCE on page 7-1.
By monitoring the total and active output current, and the DC link voltage, compensators and controllers which
help protect the V/f control performance are implemented. The operation and parameterization of those blocks
are detailed in section 11.2 - DC Link Voltage and Output Current Limitation.
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, and the factory default normally requires little or no modification. Besides, in cases where
the application allows the proper adjustments of the V/f curve, you save energy.
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/speed 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.

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 P0202 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 five different points as shown in Figure 9.2: Curve V/f on page 9-3,
although the factory default
defines a preset curve for motors (1500 rpm / 50 Hz) ou (1800 rpm / 60 Hz), as per options of P0204. In this
format, point P0 defines the amplitude applied at 0 rpm, while P3 defines the rated amplitude and frequency
and beginning of field weakening. Intermediate points P1 and P2 allow the setting of the curve for a non-linear
relationship between torque and speed, for instance, in fans where the load torque is quadratic in relation to the
speed. The field weakening region is determined between P3 and P4, where the amplitude is maintained in 100 %.

The CFW501 factory default settings define a linear relationship of the torque with the speed, overlapping points
P1, P2 and P3 at 1500 rpm (50 Hz) or 1800 rpm (60 Hz); refer to the description of P0204. In this way, V/f curve is a
straight line defined by just two points, P0136 which is the constant term or voltage in 0 Hz and the rated frequency
and voltage operation point 1500 rpm (50 Hz) or 1800 rpm (60 Hz) and 100 % of maximum output voltage).
The points P0[P0136, 0 Hz], P1[P0144, P0147], P2[P0143, P0146], P3[P0142, P0145] and P4[100 %, P0134] can be
adjusted so that the voltage and frequency relationship 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 speed, such as in centrifugal
pumps and fans, the points of the curve can be adjusted so energy saving is obtained.
NOTE!
A V/f quadratic curve can be approximated by: P0136 = 0; P0144 = 11.1 % and P0143 = 44.4 %.
9
NOTE!
If P0147 ≥ P0146 or P0146 ≥ P0145 or the V/f curve results in a segment with slope (rate) above
10 % / Hz, CONFIG (CONF) status is activated.
NOTE!
In frequencies below 0.1 Hz, the output PWM pulses are cut, except when the inverter is in DC braking.

Description:
This parameter actuates in low speeds, that is, in the range from 0 to P0147, increasing the inverter output
voltage to compensate the voltage drop in the motor stator resistance so as to keep the torque constant.
The optimum setting is the smallest value of P0136 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 (F0048, F0051 or F0070) or alarm condition (A0046, A0047 or A0050), as well as motor overheating.

The V/f curve can be adjusted in applications where the motor rated voltage is smaller than the power supply

The adjustment of the V/f curve is necessary when a quadratic approximation is desired for energy saving in
centrifugal pumps and fans, or in special applications: when a transformer is used between the inverter and the
motor or the inverter is used as a power supply.

Description:
The automatic torque boost compensates the voltage drop in the stator resistance because of active current.
Look at Figure 9.1: Block diagram of V/f scale control on page 9-2, where variable m
corresponds to the

automatic torque boost action on the modulation index defined by V/f curve.
P0137 actuates similarly to P0136, but the value set is applied proportionally to the output active current in
relation to the maximum current (2xP0295).
The setting criteria of P0137 are the same as those of P0136, that is, set the value as low as possible for the
motor start and operation at low frequencies, because values above those increase the losses, heating and
overload of the motor and inverter.
The block diagram of Figure 9.4: Block diagram of the automatic torque boost on page 9-6 shows the
automatic compensation action IxR responsible for the increment of the voltage in the ramp output according
to the increase of the active current.

Description:
Parameter P0138 is used in the motor slip compensation function, when set for positive values. In this case, it
compensates the speed drop due to application of the load on the shaft and, consequently, the slip. In this way,
it increments the output frequency (Δv) considering the increase of the motor active current as shown in Figure
9.5: Slip compensation in an operation point of the standar V/f curve on page 9-7. In Figure 9.1: Block diagram
of V/f scale control on page 9-2 this compensation is represented in the variable f
Slip
.
The setting in P0138 allows regulating with good accuracy the slip compensation by moving the operation point
on the V/f curve, as shown in Figure 9.5: Slip compensation in an operation point of the standar V/f curve on
page 9-7. Once P0138 is set, the inverter is able to keep the speed constant even with load variations.
Negative values are used in special applications where you wish to reduce the output speed considering the
increase of the motor current.
E.g.: load distribution in motors driven in parallel.

V VW Vector Control
10 V V W 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: VVW control flow 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 speed 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 VVW 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 P0137 and P0138, 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 speed regulation in permanent duty, the parameter setting in the range from P0399
to P0407 and the stator resistance in P0409 are essential for the good operation of the VVW control. Those
parameters can easily be obtained on the motor nameplate and in the self-tuning routine activated by P0408.

V VW Vector Control
10 .1 VVW VECTOR CONTROL PARAMETERIZATION
The V VW control mode is selected by parameter P0202, 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.
The V VW control setting process is simplified by the HMI “STARTUP” menu, where the relevant parameters for
the configuration of the V V W are selected for browsing the HMI.
Below are described the parameters to configure the V VW vector control setting. Those data are easily obtained
on the nameplate of WEG motors; however, in old motors or motor of other manufacturers, this information may
not be available. In those cases, it is recommended first contact the motor manufacturer, measure or calculate the
desired parameter, or, still, make a relationship with Table 10.1: Characteristics of IV pole WEG standard motors
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.

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 - Electric Installation of the user’s manual.
3. Load the correct factory default in P0204 based on the motor rated frequency (set P0204 = 5 for 1800 rpm
(60 Hz) or P0204 = 6 to 1500 rpm (50 Hz).
4. Parameter and function setting specific for the application: program the digital and analog inputs and outputs,
HMI keys, etc., according to the application requirements;
5. Activation of the VVW control: using the HMI “STARTUP” menu, the browsing is limited to the relevant parameters
to set the control mode. Set P0202 = 3; then the “STARTUP” menu will browse the relevant parameters to set
the V VW;
10
6. Parameterization of the V VW control: browsing the “STARTUP” menu, set parameters P0398, P0399, P0400,
P0401, P0402, P0403, P0404 and P0407 according to the data on the motor nameplate. If some of those data
are not available, insert the approximate value by calculation or similarity to WEG standard motor – see Ta b le
10.1: Characteristics of IV pole WEG standard motors on page 10-3.
7. Self-Tuning of the V VW control: The self-tuning is activated by setting P0408 = 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.
8. 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 P0207 again and the stator resistance measured is stored in P0409. On the other
hand, if the self-tuning fails, the inverter will indicate a fault. The most common fault in this case is F0033, which
indicates error in the estimated stator resistance. Refer to chapter 14 - Faults and Alarms.
For applications:
That can use the factory default programming of the analog and digital inputs and outputs, use the HMI
“BASIC” menu.
That require just the analog and digital inputs and outputs with programming different from the factory default,
use the HMI “I/O” menu.
That require functions such as flying start, ride-through, DC braking, rheostatic braking, etc., access and modify
the parameter of those functions in the HMI “PARAM” menu. For further information on the HMI menus, refer
to chapter 5 - Basic Instructions for Programming and Settings.

Functions Common to all the Control Modes
11 FUNCTIONS COMMON TO ALL THE CONTROL MODES
This chapter describes the functions common to all the inverter control modes V/f and VVW, 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 speed (P0134) and the time
for a linear deceleration from the maximum speed to zero.
In the CFW501, 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.
rd
3
Ramp – it is used for the inverter protection functions, such as: current limitation, DC link control, quick
stop, etc. The 3rd Ramp has priority over the other ramps.
NOTE!
The setting with too short ramp time may cause overcurrent in the output (F0070), undervoltage
(F0021) or overvoltage (F0022) of the DC link.

Note: Parameter P0680 (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 7-10.
NOTE!
The inactive status of any of the active sources activates the 1st ramp. The same occurs in option 2
(DIx) and there is no digital input for the 2nd ramp.
Acceleration time from zero to maximum speed (P0134) or deceleration from maximum speed (P0134) to zero
when the 3rd Ramp is active.
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 according to the P0150 options, aiming at containing the voltage increase in the DC link and output current.
In this way, the following of the reference by the ramp is blocked and the output speed follows the 3rd ramp for
P0133 or P0134.
When the DC link voltage is too high, the inverter may freeze the deceleration ramp or increase the output speed
in order to contain this voltage. On the other hand, when the output current is too high, the inverter may decelerate
or hold the acceleration ramp in order to reduce this current. Those actions prevent the occurrence of faults F0022
and F0070, 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.
There are two modes to limit the DC link voltage during the motor braking: “Ramp Holding” (P0150 = 0 or 2) and
“Accelerate Ramp” (P0150 = 1 or 3). Both actuate limiting the braking torque and power, so as to prevent the
shutting down of the inverter by overvoltage (F0022). This situation often occurs when a load with high moment
of inertia is decelerated or when short deceleration time is programmed.
11
NOTE!
The inverter protection functions use the 3rd ramp defined by P0106 for both acceleration and
deceleration.
CFW501 | 11-3
Functions Common to all the Control Modes
11. 2.1 DC Link Voltage Limitation by “Ramp Hold” P0150 = 0 or 2
It has effect during deceleration only.
Actuation: when the DC link voltage reaches the level set in P0151, a command is set to the “ramp” block,
which inhibits the motor speed variation according to Figure 9.1: Block diagram of V/f scale control on page
9-2 of chapter 9 V/f SCALAR CONTROL on page 9-1 and Figure 10.1: VVW control flow on page 10-2 of
chapter 10 VVW VECTOR CONTROL on page 10-1.
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” P0150 = 1 or 3
It has effect in any situation, regardless the motor speed condition: accelerating, decelerating or constant speed.
Actuation: the DC link voltage is measured (P0004) and compared to the value set in P0151; the difference
between those signals (error) is multiplied by the proportional gain (P0152); the result is then added to the
ramp output, as per Figure 11.4: Block diagram of DC link voltage limitation – Accelerate Ramp (P0152 = 1
or P0152 = 3) on page 11-6 and Figure 11.5: Example graph of the DC ling voltage limitation – Accelerate
Ramp (P0152 = 1 or P0152 = 3) on page 11-7.
11
Use recommended in the drive of loads that require braking torques at constant speed situation in the inverter
output. For example, drive of loads with eccentric shaft as in sucker rod pumps; another application is the load
handling with balance like in the translation in overhead cranes.
NOTE!
When using rheostatic braking, the function “Ramp Hold” or “Accelerate Ramp” must be disabled.
Refer to description of P0151.
P0150 – Ud Controller Type and Current Limitation
Adjustable
Range:
Properties:cfg, V/f, V V W
Access groups
via HMI:
Description:
P0150 configures the behavior of the ramp for the limitation functions of the DC link voltage and current limitation.
In those cases, the ramp ignores the reference and takes an action of accelerating (accel), decelerating (decel)
or freezing (freeze) the normal path of the ramp. That occurs because of the limit pre-defined in P0151 and
P0135 for the DC link (Ud) limitation and for current (LC) limitation, respectively.

When the option of P0150 is 1 or 3, the value of P0152 is multiplied by the “error” of the DC link voltage, seeing
that the error results from the difference between the actual DC link voltage (P0004) and the actuation level
of the DC link voltage regulation (P0151). The result is added directly to the inverter output speed in rpm. This
resource is normally used to prevent overvoltage in applications with eccentric loads.
