Chapter 1 - Safety Precautions
In compliance with EEC directives, make sure that all the safety devices required by EC standard 89/
392/CEE governing industrial automation have been incorporated in the drive before attempting to
operate it. These directives apply only in Europe and have no validity on the American continent.
This drive controls mechanical movements. It is the responsibility of the end user to ensure that
these movements do not themselves cause any danger. Do not bypass or tamper with the drive
manufacturers safety interlocks or operating limits.
Risk of fire and electric shock!
When using test apparatus like oscilloscopes to take measurements from electrically live equipment,
always connect the body of the oscilloscope to ground and always use a differential amplifier. To
ensure accurate readings, choose probes and terminals with care and make sure that the oscilloscope
is correctly set up. Refer to the manual provided by the oscilloscope manufacturer for details of how
to operate and adjust the oscilloscope correctly .
Risk of fire and explosion!
Installation of the drive in hazardous areas and in the presence of flammable substances or
combustible vapours or powders can lead to fire or explosion. Install the drive well away from
hazardous areas even if the controlled motor is suitable for use under such conditions.
Risk of crushing!
Incorrect lifting of the drive can cause serious or even fatal injury. Only suitably trained personnel
should lift the drive, and even then only with suitable lifting equipment.
Connect the drive and the motor to ground in compliance with applicable national electrical standards.
Replace any covers that may have been removed before powering up the drive. Failure to comply
with this precaution can lead to serious injury or even death.
This variable frequency drive is electrical equipment designed for use in industrial installations.
Parts of the drive are electrically live while it is functioning. The drive must therefore be installed
and opened only by a qualified electrician. Incorrect installation of the drive or the controlled motor
can damage the drive and lead to damage and injury.
The drive has no over-speed protection other than software based protection logic. Carefully follow
the instructions given in this manual and observe all local and national safety standards.
Always connect the drive to a protective earth (PE) through the ground terminals (PE2) and the
metallic casing (PE1). PIX drives and their AC power input filters have an earth leakage current
greater than 3.5 mA. EN 50178 standard specifies that in the presence of earth leakage currents
greater than 3.5 mA, the ground connection cable (PE1) must be fixed and must be doubled for
redundancy.
In the event of a fault, even if the drive has been disabled it may still cause sudden movements if it
has not been disconnected from the mains power.
Never open the drive or remove any covers while the drive is connected to the mains power supply.
See section 5.9 in this manual for the minimum delay that must be respected before any work on the
drives terminals or internal components can be performed.
Never connect the drive to mains supplies with voltage levels outside the specified range. Excess
voltage can damage the drives internal components.
It is forbidden to operate the drive without a correct ground connection. The casing of the motor
must also be grounded separately from the drive to avoid interference.
The ground connection must be comply with national electrical standards or the Canadian Electrical
Code. The drive must be grounded using a closed loop connector certified to UL and CSA standards
sized to match the gauge of the wire used. The connector must be fitted using the crimping tool
User Manual Chapter 1 - Safety Precautions 7
Page 8
specified by the connector manufacturer.
Never perform insulation testing between drive terminals or control circuit terminals.
Do not install the drive in environments where temperature exceeds the specified maximum. Ambient
temperature plays a major role in drive reliability.
If the drive displays any alarm condition, refer to the TROUBLESHOOTING section later in this manual
and recommence normal operation only once the problem has been solved. Do not use an external
routine or other such methods to reset alarms automatically.
The drive must be secured to a partition or panel constructed from heat resistant materials. The
temperature of the drives cooling fins can reach 90°C during normal functioning.
Do not touch or tamper with any drive component during normal functioning. In particular do not
alter gaps between insulation or remove insulation or covers from the drive.
Protect the drive against physical and environmental stress (high temperature, humidity, impact,
etc.).
Never apply voltage to the drives output terminals (U2, V2, W2). Likewise, never connect other
drives in parallel with the drives own outputs or bypass the drive by connecting its inputs directly to
its outputs.
Do not connect capacitive loads like power factor correction capacitors to the drives output terminals
(U2, V2, W2).
Only qualified electricians should install and start up the drive. The electrician so doing is directly
responsible for ensuring that there is an adequate ground connection and that power cables are
protected in accordance with local and national standards. The controlled motor must also be
protected against overload.
Do not perform dielectric rigidity testing on any parts of the drive. Only use appropriate test instruments
(with a minimum internal resistance of 10 k
ΩΩ
Ω/V) to measure signal voltage.

8 Chapter 1 - Safety Precautions User Manual
Storage of the drive for periods longer than two years could lead to malfunctioning of the DC
link capacitors. These must be regenerated prior to use as follows.
Before starting up the drive, leave it connected to the mains power supply for at least two
hours with no load. The drive must be connected to the power supply but not enabled in
order to regenerate the capacitors.
The terms inverter, controller and drive are interchangeable in industrial automation
contexts. This manual uses the terms drive and inverter.

1.1 Power and ground connections
1) TDE Macno S.P.A. drives are designed for use with standard three phase mains power supplies, symmetrical with
respect to ground (TN or TT mains supplies).
Single phase drives must be connected to one phase, neutral and ground. Three phase drives must be connected
to all three phases plus ground.
2) In the case of an IT mains supply, use a star/delta transformer with secondary wiring referenced to ground.
If IT mains power is used, loss of insulation in onen of the other devices connected to the same circuit
can cause the drive to malfunction if no star/delta transformer is provided.

Chapter 2 - General Description
DVS digital drives are designed to control the speed of three phase electric motors. They can control motors with a power
range from 0.25 kW to 0.75 kW (220 - 240 V) and from 0.35 HP up to 1 HP (220 V).
The drive rectifies the voltage of the mains power supply to obtain an intermediate circuit voltage, then uses an inverter bridge
applying sinusoidal PWM modulation to generate a three phase power supply with variable voltage and frequency permitting
regular, smooth motor control even at very low speeds.
Feed voltages to the various control cards are obtained from a switching power supply that also draws its power from the
intermediate circuit.
The inverter bridge is based on IGBT (Insulated Gate Bipolar Transistor) devices. Output is protected against short circuits
between the phases and to ground. If more than one motor is driven in parallel by a single drive (obviously of adequate power)
motors can be switched in and out independently even during normal drive functioning (see section 5.2.3).
If the motors used are not specifically designed for inverter control, a drop in output current of around 5 - 10% must be
allowed for. If nominal torque is demanded from such a motor at low speeds, an auxiliary motor cooling fan will be necessary
to dissipate the heat generated. If the necessary cooling assistance cannot be provided, then the motors will have to be oversized. In either case the user should contact the technical service of the motor manufacturer for further information.
If a motor has to function at a frequency greater than its nominal frequency, the user should again contact the manufacturers
technical service to ascertain what mechanical problems (bearing wear, balancing problems, etc.) could be incurred.
DVS drives can be controlled in a number of ways:
- via their control terminals
- using the control keys and display
- over an RS 485 serial line
- using a standard PC control program
Note!
The electronic control circuit terminals are electrically separate from the power circuit terminals, but the
control microprocessor is linked to the potential of the DC stage.

3.1. Storage and transport
3.1.1. General
DVS drives are carefully packed for shipment. Transport must be undertaken using adequate means (see weights). Respect
all instructions and symbols printed on the packaging. The same applies to drives removed from their transport packaging for
installation in control cabinets.
Perform the following checks as soon as you receive your drive.
- Check that the packaging has not been visibly damaged.
- Check that the details on the delivery bill correspond to those of the original order.
Unpack the drive carefully and perform the following checks.
- Check that no part of the drive has been damaged during transport.
- Check that the drive delivered corrsponds to that ordered.
If any damage is found, or if the drive is either incomplete or incorrect, notify the suppliers sales department immediately.
The drive must only be stored in dry places and within the specified storage temperature range.
NOTA!
Excessive temperature variations can cause condensation to form inside the drive. While this may be
acceptable under certain storage conditions (see section 3.3.1 Ambient conditions and standards),
the presence of condensation is absolutely unacceptable under normal drive operating conditions. Before
powering your drive on for the first time, always make sure that there is no condensation inside it!

Choose a drive to suit the nominal current of the controlled motor. The drives nominal output current must be equal to or
greater than that required by the controlled motor.
The speed of an asynchronous motor depends on the number or terminal pairs it has and on its operating frequency (as
specified on the data plate and in the catalogue). If a motor has to be run above its nominal speed, consult the manufacturers
technical service to ascertain what mechanical problems may be incurred (bearing wear, balancing problems, etc.). Also
contact the manufacturers technical service to ascertain what thermal problems may be incurred if the motor has to be run
at a frequency below approximately 20 Hz (e.g. insufficient cooling if no auxiliary ventilation is provided).

Disposing of the drive
DVS drives must be disposed of as electronic waste in compliance with national legislation.
The front covers are made from recyclable ABS.
3.3.2. Mains input and drive output connections
DVS drives must be connected to a mains supply capable of providing symmetrical short circuit power better than or equal
to the values given in table 3.3.2.1. See section 5.7.1 for information on the addition of mains chokes.
See table 3.3.2.1 for the permitted mains voltages. Cyclical phase direction is irrelevant. Voltages below the minimum
tolerance threshold cause the drive to lock.
The drive can be restarted automatically after an alarm condition occurs (see section 6.15 for further details on this function).
NOTA!
DVS drives and mains input filters have earth leakage currents greater than 3.5 mA. EN 50178 standard requires that in the
presence of earth leakage currents greater than 3.5 mA, the ground connection (to the PE terminal) must be fixed.
Under certain circumstances it may be essential to add mains chokes and EMI filters to the drive input.
Refer to the Chokes and filters section.

4.3. Motors
DVS drives are designed for open or closed loop control of standard asynchronous motors.
4.3.1. Asynchronous AC motors
FOR BEST RESULTS:
Choose an asynchronous motor with a minimum slip of 3-5 %, with a single cage rotor, designed for use with an
inverter.
a) Minimum motor size. Nominal motor current must not be less than 30% of nominal drive current @ 230V.
b) General purpose motors (i.e. motors not specifically designed for inverter control) must only be used if an additional
output choke is fitted.
c) We recommend that you use special motors with reinforced insulation designed for inverter control. Motors of this
type do not require the drive to be fitted with an output choke.
The electrical and mechanical specifications of standard asynchronous motors refer to a specific functioning range. When
controlling motors of this type with an inverter, always bear the following points in mind.
Can standard asynchronous motors be used?
DVS series drives can be used with standard asynchronous motors. Certain characteristics of these motors, however, have
a major influence on performance. Pay special attention to the following considerations. Also bear in mind what section
3.3.4 Output has to say about motor power ratings and voltages.
Star or delta connection?
Motors can be wired up either in a star or a delta configuration. Star wired motors are generally easier to control and star wiring
is therefore to be preferred under most circumstances.
User Manual Chapter 4 - Installation 21
Page 22
Cooling
Asynchronous motors are normally cooled by a fan keyed directly on to the motor shaft. Care must be taken, however,
because fan efficiency drops at low motor speeds and the motor may receive insufficient cooling. Discuss motor operating
conditions with the motor manufacturers technical service to ascertain whether it is necessary to provide additional ventilation
(forced cooling).
Functioning at speeds above nominal speed
If a motor has to operate above its nominal speed, contact the manufacturers technical service to ascertain what mechanical
problems (bearing wear, balancing problems etc.) and what electrical losses may occur as a result.
Motor specifications you must know for inverter control
Motor data plate specifications:
- Nominal motor voltage
- Nominal motor current
- Nominal motor frequency
- Nominal motor speed
- Power factor (Cos ϕ)
- Number of terminal pairs
- Connection type (star/delta)
Motor protection
Use of Klixon protectors in motor windings
The contacts of the Klixon overheating protectors can be used to disable the motor either via auxiliary control circuits or
using the input to signal an alarm condition.
NOTA!
Drive current limitation
Current limitation can be used to protect the motor against damaging overloads. To do so, the current limit and overload
control parameters must be set so that current to the motor always remains within the motors acceptable limits.
NOTA!
Output chokes
In certain cases output chokes may be needed to protect the winding insulation of standard motors. See section 5.7.2.
Output chokes.
The motors Klixon interface circuit can be considered and managed to all intents and purposes like a
signaling circuit. Connections to the motors Klixon protectors must therefore use a shielded twisted
pair cable laid if possible not parallel with other motor cables or at a distance of at least 20 cm (8 inches)
from them.
Bear in mind that current limitation can only protect the motor against overheating caused by overload,
and not against overheating caused by inadequate cooling.
Always fit the windings of motors destined for use at low speeds with the necessary temperature control
plates!

5.2.3. The rectifier bridge and intermediate circuit
Mains power is rectified and filtered by capacitors. All models of PIX drives incorporate a precharge resistance diode bridge.
If over-voltage (OV signal) or under-voltage (UV signal) occurs in the intermediate circuit, no power can be drawn from it
because the inverter bridge locks.
During normal functioning, the DC voltage of the intermediate circuit UDC has a value equal to ULN * 2. If the motor is turned
by its load (as occurs during deceleration or braking), power flows into the intermediate circuit through the inverter bridge.
Voltage in the intermediate circuit therefore increases. The inverter bridge locks at a predetermined voltage, and the contacts
between terminals 1 and 3 open (provided the relay has been programmed as an alarm state signal). See section 6.15 for
details on resetting.

5.2.3. The inverter bridge
The inverter bridge features IGBT (Insulated Gate Bipolar Transistor) technology in all models of DVS drive. The inverter
bridge is protected by internal circuitry against over-voltage, over-current, short circuit between phases and short circuit to
ground. In the event a fault, the inverter bridge locks and the contacts between terminals 1 and 3 open (provided the relay has
been programmed as an alarm state signal). See section 6.15 for information on resetting.
The drive can be restarted automatically after an alarm condition. (See section 6.15 for further information on automatic

Variable voltage output is derived from the intermediate circuit voltage using PWM technology. Special sinusoidal modulation
in conjunction with the motors own inductance produces an extremely good sinusoidal curve for the output current I2. The
voltage/frequency ratio is programmable and can be adapted to suit the motor being controlled.
More than one motor can be connected in parallel to the drive output. Motors may run at different speeds even though they
have the same number of terminal pairs, because motor slip can vary with the load applied and motor characteristics may
vary too. Motors can also be switched in and out individually, though great care must be taken when doing so.
Switching a motor in or out causes voltage peaks by interrupting an inductive current flow. These voltage peaks do not
normally disturb the drive output provided the motor is a low power model and other motors remain connected to the inverter
after it is switched out.
If the motor being switched out is the last motor connected to the drive, make sure that the motors
magnetising current has dropped to zero before switching it out. the best way of doing this is to lock the
inverter bridge and disconnect the motor only after a fixed delay calculated to suit the characteristics of
the motor, in practice from about 0.5 seconds up to a number of seconds.
Motors can likewise be switched in to an already functioning inverter one at a time. If you wish to do so, bear in mind that the
instant the motor is connected its inrush current far higher than its nominal current. The drive must therefore be carefully
selected so that inrush currents do not exceed the drives nominal current. You must also consider the overload that the drive
is able to cope with if the duty cycle during which the new motor is connected coincides with the limited period for which
overload is permitted.
More than one inverter cannot work directly in parallel.

5.4. The RS 485 serial interface
5.4.1. General
With DVS drives, an RS 485 serial line can be used to transmit data over a twisted pair cable made of two symmetrical
twisted wires with a common shield. Maximum data transmission speed is 38.4 KBaud.
Transmission uses a standard differential RS 485 signal (half-duplex).
Up to a maximum of 32 DVS drives can be connected in Multidrop configurations.
The JP7 serial line jumper
The RS 485 serial line is supported by terminals 15, 16 and 17 on the DVS drive control card.
The differential signal is transmitted to terminal 16 and terminal 17. To prevent interference, termination resistors [100 Ohm]
must be fitted at the beginning and end of the RS 485 serial lines physical connection cables.

Figure 5.5.1.1: Control via terminals, typical connection schematic
NOTA!
The control input connections shown above represent the most common connection solution for NPN
control. See below for further examples.
5.5.2. Design constraints
The wires for the analog signals must be shielded (connection to terminals 9, 10, 11).
The shielding must be connected to the PE terminal at only one side.
Grounding of the reference potential
The terminal wire shielding potential must normally be grounded. Jumper J7 links the potential of terminal 9 (GND 0V,
control reference) to protective earth (PE).
If a single installation comprises more than one drive, the different potentials of their terminal wire shields must be connected
in common to the control panels ground bus.
Direct connection to PLC inputs/outputs
Observe the following points if control commands or references are obtained directly from PLC inputs/outputs.
The PLCs 0V terminal must normally be grounded. if this is done, the drive control reference potential (J7 NOT fitted) must
not be grounded.
To ensure good immunity to interference, connect a 0.1mF 250V DC capacitor between terminal 9 and
ground. If more than one drive is present in a single installation, this must be done for each individual
drive.

Characteristics and limitations
- Drives installed in homogeneous groups must all be of the same model.
- All input chokes must be identical (same specifications and same supplier).
- All drives must receive power simultaneously. In other words they must all share the same switch/line contactor.
- No more than 6 drives must be connected in parallel to the same mains supply.

NOTA!
Determine the nominal current of chokes on the basis of the nominal current of the standard motors
whose power ratings are specified in table 3.3.2.1.
5.7.2. Output chokes
DVS drives can be used with general purpose motors as well as motors specifically designed for inverter control. Motors
designed for inverter control normally have better insulation to withstand PWM voltages.
The following are examples of applicable reference standards.
Motors designed for control by inverters do not require special inverter output filters. Standard motors on the other hand, especially
those with long cables (typically longer than 30 metres) may need a choke on the inverter output to keep the voltage wave form
within specified limits.
The nominal current of these chokes must be approximately 20% greater than that of the inverter itself to compensate for
additional losses caused by modulation of the output wave form.
NOTA!
At the drives nominal current and a frequency of 50 Hz, output chokes cause an output voltage drop of
about 2%.

phases to generate braking torque. The machines kinetic energy is dissipated inside the motor in the form of heat.
The DC braking function cannot provide intermediate braking [e.g. rapid braking from 1400 to 1200 rpm],
but only braking to zero speed from already low speeds. If required, braking current can be measured

Commands & Referencies
S.200 Cmd source sel (Command source selection)
It defines the use of the main commands START and STOP .
S.200 = 1 START & STOP via terminals
In this configuration the commands are active through the drive terminals.
The motor START command can be performed by applying the specific logic level (high level +15V) ,
to the Digital Input 1 (terminal 5), factory set as RUN If this connection is removed, the motor
will STOP with the set ramp time.
For this connection refer to figure 5.3.2.1.
NOTE!
NOTE!
Main Commands Logic Control:
START & STOP
After a cycle of main supply voltage, the drive can be started only according to the settings of
P.003 Safety parameter, which allows the Start/Stop commands to respond to Edge or Level sensitive
signals (see chapter 7.6 for more details).
Other configurations for the setting of the "main commands" are described in the chapter
PARAMETERS, section Commands.
The START & STOP function configuration is correlated to other functions and parameters as well as the
mode to REVERSE the motor speed.
These functions allow additional control logic and safety control.
For further information, see chapter PARAMETER, section Commands .
MOTOR SPEED REVERSAL
There are several way to REVERSE the speed direction of the motor.
As a default factory setting, the Digital Input 2 (terminal 7) is programmed to this purpose.
All of the frequency references or other variables controlled with digital setting or analog signal, can be
programmed either with positive or negative values. The polarity of the value (Digital or Analog) will determine the
motor rotation direction, without the use of any external HW commands.
Despite the polarity of the reference, the REVERSE command, if programmed on a digital input, will always
reverse the speed direction of the motor.
S.201 Max ref freq (Maximun reference frequency)
It is the threshold for the analog or digital reference and the maximum speed for both directions.
This parameter applies to the sum of the two references value available on the drive.
64 Chapter 7 - Parameters Description User Manual
Page 65
S.202 Ref 1 Channel (Reference 1 channel)
It defines the source from where the Reference 1 is provided and controlled.
For further details please refer to chapter FREQ & RAMPS, section Reference Source.
S.203 Frequency ref 0 (Frequency reference 0)
Digital speed reference.
It is also the first digital frequency of the Multispeed selection (F.100F.116).
It is possible to set setting with positive or negative values.
The polarity will determine the sense of rotation of the motor.
In either polarity the setting the HW Reverse command is active (when enabled).
The maximum settable value is correlated to Max ref freq (S.201).

S.301 Dec time 1 (Deceleration time 1)
The ramp control can be set to allow a programmable delay (in seconds), for the acceleration and deceleration
times of the drive reference.
This delay time will have to be set on the final system (motor and load), being strictly dependant from the inertia

Functions
S.400 Manual boost [%]
The resistive impedance of the stator windings causes a voltage drop within the motor, which result in a reduction
in torque in the lower speed range.
Compensation can be made for this effect by boosting the output voltage.
This compensation is carried out continuously across the whole speed range in proportion to the output current
but it is most effective at low speed.

The setting is in percentage of the Max out voltage (S.100).
NOTE!
When custom V/f shape is selected (P.060 = 0):
P. 0 6 4 parameter represents the return point of the output voltage, on the linear characteristic of V/f
ratio (see figure 7.3.3).
S.401 Auto boost en (Automatic boost enabling)
The boost can be automatically controlled by the enabling of this parameter. The control is continuously carried
out in the whole speed range.
The Auto boost must be disabled when a multiple motor connection is being used.
NOTE!
The automatic boost is automatically calculated during the execution of drive/motor self tuning (S.901
parameter).
It is anyway possible to obtain an "Oveboost" at low speed, increasing the value of the manual boost
(S.400 parameter).

S.450 Slip compensat (Slip compensation)
If an induction motor is being used, the mechanical speed will vary with the load due to the slip of the motor.
In order to adjust for this speed error the slip compensation can be used.
During this calibration, make sure that the drive is not in a current limit condition.
If this compensation is set too high it can cause instability.
The changing will be carried out as a percentage of the nominal slip, calculated when set the motor plate date.
The Slip compensation will act directly on the output frequency of the drive. To this purpose the parameter
Max output freq (P.080) expressing the percentage of the Max ref freq (F.020), has to be set to a value
including:
Max ref freq value + Slip compensat value.
(See also chapter PARAMETER, section Output Frequency Limit).
The Slip compensation must be disabled when a multiple motor connection is being used.
S.451 Slip comp filter (Slip compensation filter)
It is the response time (in seconds) for the reaction of the function.
Increasing this value helps damping oscillations that may arise with load steps (especially negative ones).

Utility
S.900 Measure stator R (Measurement of stator resistance)
It measures the stator resistance of the motor connected.
This will help to provide a smooth and uniform value of the output torque through the whole speed range.
The control is assisted by the use of the Automatic boost (P.401).
Do not perform any tune when a multiple motor connection is being used.
S.901 Save parameters
Every changing of each parameter, is accepted and executed by the drive.
However, the permanent storage of them, is performed only by the execution of this command.
The lack of this operation will cause the loss of every changed parameter when the power is disconnected from
the drive.

Enabling Virtual I/O
Through a virtual setting via serial line or fieldbus, it is possible to use all the functions available on the digital inputs and
perform a direct control of the digital and analog outputs.
The setting can be carried out in such configurations, where the digital commands are a mix of virtual and terminals and
the outputs are a mix of virtual and drive function.
The virtual assignment can be performed through the parameters H.000H.022 in the HIDDEN menu (for further
information please see this chapter).
Below are the reported the drawings describing the combination between the byte of the virtual I/Os and the drive
terminals, with the relative decoder mask.
The switch between the virtual commands and the terminal ones and between the virtual output or the drive
functions, is determined by programmable mask I.400I.450.
These parameters have to be managed bitwise. At each bit corresponds a switch, as follows.
Bit value Inputs Outputs

The DVS provides as a standard an RS485 serial line.
For the connection of the serial line, a 9-pin SUB-D connector, named JP7 or an AMP connector named JP15 (see
chapter 5.4.1 Serial Interface General). are available on the regulation card.
Through the serial line, all the parameters and variables can be written and read.
When control of the main command through serial line is needed, it is necessary to set the Cmd source sel (P.000) as
follows:
P.000 = 2 Terminal or Virtual
P.000 = 3 Serial

I.601 Serial link bps (Serial link bit per second)
It defines the Baud rate (bit per second) concerning the serial line communication speed.
The selection is through the following code:
I.602 Device address
Address at which the drive can be accessed if it is networked via the RS485 interface.
The range of the selectable addresses is between 0 and 99.
As reported in the chapter 5.4.1 (Serial Line General), it is possible to perform a Multidrop configuration with a
maximum of 20 devices.
Further information about are reported in this chapter.
I.603 Ser answer delay (Serial link answer delay)
Minimum delay setting between the reception of the last byte and the start of its answer.
The delay will help avoid conflicts on the serial line, when the RS485 interface is not preset for an automatic Tx/
Rx communication.
The Ser answer delay (I.603) parameter is specific for the standard serial line RS485.
Eg: if on the master the Tx/Rx delay communication is 20ms max, the setting of Ser answer delay (I.603)
parameter will have to be higher than 20ms: 22ms.
I.604 Serial timeout (Serial link timeout)
It sets the time that elapses between the sending/receiving of a byte and the next one.
If this time is longer than the setting and no byte is detected (sending/receiving), the action will be the one
programmed in the parameter I.605
The alarm won't be active when set at 0 second.
It will be displayed with the message "St".
NOTE!
Even if the timeout control function is enabled at the drive power-on, the detection of "St" alarm is
temporary non active.
The detection of the alarm will be automatically activated after the first restore of the communication
between master and slave.

F.250 Ramp S-shape
The S-shaped ramp can be useful to obtain a smooth behaviour of the system during the end of the acceleration
or close to the zero speed during the deceleration.
The value (in seconds) of the S-shaped ramp is added to the ramp time of the linear profile.
The ramp time is thus lengthened by the value of the S-curve constant.

Figure 7.5.5: Jump Frequencies
When the frequency reference is set to a value within the tolerance band, the frequency output assumes the
following behavior.
Example:
A) Increasing the reference from lower value of F. 27 1 or F. 27 2
F. 27 1 = 30Hz (first forbidden frequency threshold)
F. 27 0 = 1Hz (tolerance band: 29Hz.31Hz)
Setting of frequency reference = 29,5Hz
Frequency output = 29Hz
Setting of frequency reference = 30,5Hz
Frequency output = 29Hz
B) Decreasing the reference from higher value of F.2 71 or F.2 72
F. 27 1 = 30Hz (first forbidden frequency threshold)
F. 27 0 = 1Hz (tolerance band: 29Hz.31Hz)
Setting of frequency reference = 30,5Hz
Frequency output = 31Hz
Setting of frequency reference = 29,5Hz
Frequency output = 31Hz
The user can set any frequency reference, but if its value is within the forbidden range, the inverter will
maintain automatically the speed out the limit of the tolerance band.
During the ramp execution the forbidden frequencies have not any influence, so the output frequency will be
linearly generated.

Slip Compensation
P.100 Slip compensat (Slip compensation)
If an induction motor is being used, the mechanical speed will vary with the load due to the slip of the motor.
In order to adjust for this speed error the slip compensation can be used.
During this calibration, make sure that the drive is not in a current limit condition.
If this compensation is set too high it can cause instability.
The changing will be carried out as a percentage of the nominal slip, calculated when set the motor plate date.
The Slip compensation will act directly on the output frequency of the drive. For this purpose the parameter
Max output freq (P.080) expressing the percentage of the Max ref freq (F.020), has to be set to a value
including:
Max ref freq value + Slip compensat value.
See chapter "PARAMETERS", section "Output Frequency Limit".
The Slip compensation must be disabled when a multiple motor connection is being used.
P.101 Slip comp filter (Slip compensation filter)
It is the response time (in seconds) for the reaction of the function.
Increasing this value helps damping oscillations that may arise with load steps (especially negative ones).

Boost
P.120 Manual boost [%]
The resistive impedance of the stator windings causes a voltage drop within the motor, which result in a reduction
in torque in the lower speed range.
Compensation can be made for this effect by boosting the output voltage.
This compensation is carried out continuously across the whole speed range in proportion to the output current
but it is most effective at low speed.

The regulation of the Boost level will be between 0% (setting the inputs at 0V - 0mA - 4mA) and 100% of the

The magnetizing current of the motor, has approximately the no load current value at rated voltage and frequency.
A control of this variable is performed with the changing of its gain. .
The benefit is substantially an availability of motor higher torque at low speeds, obtained with a modality similar

The parameter (current symmetry) is used to eliminate any oscillation or beat in the motor current resulting from
tolerances or configurations capable of generating oscillations within the Inverter/cable/ motor system.
The "0" value set at the factory is effective in many cases.
If necessary this value can be altered (0...100) to provide adaptation to the application in question.
During the calibration of the optimum value it is recommended to set the variations of this parameter with slight
increases.

SW Current Clamp
P.180 SW clamp enable (Software current clamp enabling)
To optimize the performance of the inverter, it is necessary to be able to accelerate and decelerate during the
whole ramp time with the maximum current that the inverter can supply to the motor.
The setting of very short ramp times, that would cause an exceeding of the allowable current limits of the drive,
activates the "Current Clamp"circuit avoiding to reach the overcurrent limits and the consequent "OC" trip.
The intervention of the "Current Clamp" circuit, has as consequence an increase of the real time in which the
final speed is obtained.
It is anyway possible the disabling of the function, setting this parameter at zero.

Current Limit
The drive is provided with an active current limited function.
It is possible to select different current limits, during the ramps or at steady state.
Current limitation is achieved by a PI regulator effect on speed reference (see P.2 0 6 parameter).
P.200 En lim in ramp (Enabling limit in ramp)
P.200 = 0 Function disabled.
User Manual Chapter 7 - Parameters Description 95
Page 96
P.200 = 1 Enabling of the current limit control during the ramps.
P.200 = 2 Ramp-curr ctrl
During speed acceleration or deceleration, if the current value exceeds the setting of P. 2 0 1 (Current
limit during the ramp), the ramp stage will be momentary blocked and the speed kept at the value
reached in this moment.
When the current will decrease again below this limit, the ramp will be restarted with the profile set.
The ramp time is thus lengthened by the execution of this control.
P.201 Curr lim in ramp (Current limit in ramp)
Value of the current limit during the ramps.
It is as percentage of the nominal current of the drive (see also parameter d.950, chapter DISPLAY).
P.202 En lim in steady (Enabling limit in steady)

It is as percentage of the nominal current of the drive (see also parameter d.950, chapter DISPLAY).
P.204 Curr ctrl P-gain (Current control proportional gain)
Proportional gain of the current regulator.
a setting too low could have a slow reaction on the regulation response.
a setting too high could can have a too fast reaction with consequent oscillations of the system.
P.205 Curr ctrl I-gain (Current control integral gain)
Integral gain of the current regulation.
a setting too low could have a slow reaction on the regulation response.
a setting too high could can have a too fast reaction with consequent oscillations of the system.
P.206 Curr ctr feedfwd (Current control feed forward)
As described in the figure below, the setting of the feed-forward, allows to avoid the drive trip for overcurrent
(OC) during fast acceleration of the load.
When the current exceeds the value of Curr lim in ramp, a quick frequency step (percentage of the motor
rated slip), is automatically sutracted to the reference.
In this case the ramp is extended in order to keep the current level under this limit.
A shortening of the extended ramp time, can be of course achieved excluding the load.
This function operates only during the ramp time (not in steady state).

DC Link Limit
The function when enabled, performs a control on the voltage level of the DC link bus capacitor.
During fast deceleration if the load has a big inertia, the DC link value can suddenly increase close to the alarm
threshold. In this case the ramp is controlled keeping the voltage level within safety values.
Consequently the deceleration ramp time is automatically extended, in order to achieve the deceleration of the load,
trying to avoid an eventual block for "overvoltage" (OV alarm).
As for the current limiter, the DC-Link controller is PI-based, with the addition of a programmable feed forward term.
P.220 En DC link ctrl (Enabling DC link control)
P.220 = 0 Function disabled.
P.220 = 1 Enabling of the DC link control function.
P.220 = 2 DC-Ramp ctrl
During fast deceleration, if the DC link level increase close to the alarm threshold, the ramp stage
will be momentary blocked and the speed kept at the value reached in this moment.
When the DC link level, will decrease again within the internal safety values, the ramp will be
restarted with the profile set. The ramp time is thus lengthened by the execution of this control.
