About the CFW100
3 ABOUT THE CFW100
3.1 ABOUT THE CFW100
The frequency inverter CFW100 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 torque.
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 CFW100 can be viewed in the block diagram of Figure 3.1 on page 3-1 and Figure
3.2 on page 3-2. 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.

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 SETTING OF DISPLAY INDICATIONS
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.

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).

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 interface, 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 300.0 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.

Reference Frequency on page 7-7.
7.2 REFERENCE FREQUENCY
The frequency reference is the value applied to the input of the acceleration ramp module (P001) to control the
frequency applied to the inverter output (P002) and consequently the motor shaft speed.
7
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 500.0 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 300.0 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 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 300.0 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 300.0 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 300.0 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.

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.

7.2.4 Reference via Electronic Potentiometer
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.

7.2.5 Frequency Input FI
The behaviors of the analog input and frequency input are described in details in section 12.4 FREQUENCY INPUT
on page 12-6. Thus, after the proper signal treatment, it is applied to the ramp input according to the selection of
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 frequency (P402) or on the motor rated
frequency (P403). In the CFW100, 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) 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.

NOTE!
When the Coast Stop mode is programmed and the Flying Start function is disabled, only activate
the motor if it is stopped.
NOTE!
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.
7.3.1 Control via HMI Inputs
Contrary to the network interfaces and SoftPLC, the HMI commands do not access the inverter control word
directly, because of limitations of key functions and HMI behavior. The HMI behavior is described in chapter 4 HMI
AND BASIC PROGRAMMING on page 4-1.
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,
because there are several functions for DIx that are defined by the applications. Such digital input functions are
detailed in section 12.5 DIGITAL INPUT on page 12-8.

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 CFW100 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.
„ „ V V 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.

V/f Scalar Control
9 V/f SCALAR CONTROL
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).

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 %.

Figure 9.2: Curva V/f
The factory default setting of the CFW100 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

applications: when a transformer is used between the inverter and the motor or the inverter is used as a power

Description:
The automatic torque boost compensates the voltage drop in the stator resistance because of active current.

modulation index defined by V/f curve.
P137 actuates similarly to P136, but the value set is applied proportionally to the output active current in relation
to the maximum current (2xP295).
The setting criteria of P137 are the same as those of P136, 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 9.6 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 P138 is used in the motor slip compensation function, when set for positive values. In this case, it
compensates the speed drop due to the application of load on the shaft and, consequently, the slip. Thus, it
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 fSlip.
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.

Negative values are used in special applications where you wish to reduce the output frequency considering
the increase of the motor current.

V V W Vector Control
10 V V W VECTOR CONTROL
The V V W 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 V W 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 V V W control instantly obtains the motor torque and slip. Thus, the
V V W actuates in the output voltage compensation and slip compensation. Therefore, the V V 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 V W control, the
parameter setting in the range P399 to P407, and the stator resistance in P409 are essential for the good operation
of the V V W control. Those parameters can be easily obtained on the motor nameplate.

10.1 VVW VECTOR CONTROL PARAMETERIZATION
The V V W 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 V V 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 V W 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 V W control performance.

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 V VW 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 CFW100, three ramps with different functions were implemented:
„„
1st Ramp – standard for most functions.
„„
2nd 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.

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 Ram 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 set 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.
„„
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.

In those cases, the ramp ignores the reference and takes an action of accelerating (accel), decelerating (decel)
or freezing (hold) the normal path of the ramp. That occurs because of the limit pre-defined in P151 and P135
for the DC Link (Ud) Limitation and for Current (LC) Limitation, respectively.
In order to disable the DC link limitation (Ud) and/or the current limitation, you must set P151 > 410 V and
P135 > 2xInom, respectively.

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;
„„
It has a faster action than the “Decelerate Ramp” mode.
„„
It acts in the motorization and regeneration modes.
11.2.4 Current Limitation Type “Decelerate Ramp” P150 = 0 or 1:
„„
It prevents the motor from collapsing during torque overload in the acceleration or constant frequency.
„„
Actuation: if the motor current exceeds the value set in P135, a null value is forced for the frequency ramp input
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 spinning, 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 spinning 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.

P332 – Dead Time
Adjustable
Range:

Setting:
0.1 to 10.0 s
1.0 s
Properties:
Description:
Parameter P332 sets the minimum time the inverter will wait until driving the motor again, which is necessary
for the demagnetization of the motor.
For the Ride-Through function, the time is counted as of the line drop. However, in the actuation of the Flying
Start function, the count starts after the application of the “Run/Stop = Run” command.
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 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.

reference from the minimum point (0 V / 0 mA / 4 mA or 10 V / 20 mA), and it will be directly related to the
minimum frequency set in P133. Check Figure 12.1 on page 12-2.
If the parameter is set as Active (P230 = 1), the signal in the analog inputs will have a dead zone, where the

12.4 FREQUENCY INPUT
A frequency input consists of a fast digital input able to convert the frequency of the pulses in the input into a
proportional signal with 10-bit resolution. After the conversion, this signal is used as an analog signal for frequency
reference, process variable, for example.
According to the block diagram of Figure 12.4 on page 12-7, the signal in frequency is converted into a digital
quantity in 10 bits by means of the block “Calc. Hz / %”, where parameters P248 and P250 define the input signal
frequency band, while parameter P022 shows the frequency of the pulses in Hz.

P250 - P248
Parameters P248 and P250 determine the operation range of the frequency input (FI), while parameters P249 and
P247 determine the offset and gain, respectively. For example, FI = 2000 Hz, P248 = 1000 Hz, P250 = 3000 Hz,
P249 = -70.0 % and P247 = 1.000, thus:
((
FI = 2000 - 1000
3000 - 1000
(
(
x (100 %) - 70 % x 1.000 = 20.0 %
The value FI = -20.0 % means that the motor will spin in the opposite direction with a reference in module equal
20.0 % of P134, with the function of the FI signal for "Frequency Reference" (P221 = 4).

When P246 = 1, the digital input DI3 is pre-defined for frequency input, regardless the value of P265, with
operating capacity in the band from 0 to 3000 Hz in 10 Vpp.
The time constant of the digital filter for the frequency input is defined by means of parameter P245.

Faults and Alarms
13 FAULTS AND ALARMS
The problem detection structure in the inverter is based on the fault and alarm indication.
In case of fault, the locking the IGBTs and motor stop by inertia will occur.
The alarm works as a warning for the user of critical operating conditions and that may cause a fault if the situation
is not corrected.
Refer to chapter 6 of the CFW100 user manual and the chapter QUICK REFERENCE OF PARAMETERS, ALARMS
AND FAULTS on page 0-1 of this manual to obtain more information regarding Faults and Alarms.
13.1 MOTOR OVERLOAD PROTECTION (F072 AND A046)
The motor overload protection is based on the use of curves that simulate the heating and cooling of the motor in
cases of overload. The motor overload protection fault and alarm codes are F072 and A046 respectively.
The motor overload is given considering the reference value In x FS (motor rated current multiplied by the duty
factor), which is the maximum value at which the overload protection must not actuate, because the motor can
work continuously at that current value without damages.
However, for that protection to actuate properly, the winding-temperature supervision (which corresponds to the
time of heating and cooling of the motor) is estimated.
This winding-temperature supervision is approximated by a function called Ixt, which integrates the output current
value from a level previously defined by P156. When the accumulated value reaches the limit, an alarm and/or
fault are indicated
In order to ensure greater protection in case of restart, this function keeps the value integrated by the function
lxt in the inverter non-volatile memory. Thus, after the energizing, the function will use the Ixt value saved in this
memory to perform a new evaluation of overload.
P156 – Overload Current
Adjustable
Range:
Factory
Setting:
0.1 to 2xInom
P156 =
1.2xInom
Properties:
Description:
These parameters define the motor overload current (Ixt - F072). The motor overload current is the current value
(P156) based on which the inverter will understand that the motor is operating in overload
The greater the difference between the motor current and the overload current (P156) the faster the actuation
of fault F072.
It is recommended that parameter P156 (motor overload current at rated speed) be set at a value 10 % above
the used motor rated current (P401).
In order to deactivate the motor overload function just set parameters P156 to values equal to or above two
times the inverter rated current P295.
Figure 13.1 on page 13-2 shows the overload actuation time considering the normalized output current in
relation to the overload current (P156), that is, for a constant output current with 150 % of overload, fault
F072 occurs in 60 seconds. On the other hand, for output current value below P156, according to the output
frequency, fault F072 does not occur. Whereas for values above 150 % of P156 the fault actuation time is below
60 s.

13.3 OVERCURRENT PROTECTION (F070)
The ground fault and output overcurrent protections act very fast by means of the hardware to instantly cut the
output PWM pulses when the output current is high. Fault F070 corresponds to a current surge between output
phases.
The protection current level depends on the used power module so as the protection is effective, still this value is
well above the inverter rated operating current (P295).

identifies the power hardware in order to obtain information on the module voltage, current and trigger, the power
module.
Alarm A084 indicates something wrong happened during the identification of the hardware: nonexistent inverter
model, some loose connection cable or damaged internal circuit.
NOTE!
When this alarm occurs, contact WEG.
13.9 FAULT IN THE CPU (F080)
The execution of the inverter firmware is monitored at several levels of the firmware internal structure. When some
internal fault is detected in the execution, the inverter will indicate F080.

In case the flash memory module (MMF) has been previously loaded with parameters of a “different” version from
that of the inverter to which it is trying to copy the parameters, the operation will not be executed and the HMI will
indicate fault F082. It is considered a “different” version those which are different in “x” or “y”, assuming that the

not compatible with the CFW100 firmware version.
In this case, it is necessary that the user recompile the project on the WLP, considering the new CFW100 version
and redo the download. If that is not possible, the upload of this application can be done with the WLP, provided
that the application password is known or is not enabled.
