IntroductionChapter 1
SYSDRIVE 3G3FV Inverter Models
• The following 200- and 400-V class 3G3FV Inverter models are available.
• A total of 21 types of Inverters are available for maximum applicable motor capacities of 0.4 to 300 kW.
Voltage classProtective structureMaximum applied motor capacityModel
Selection of Modes for Vector Control and V/f Control
• The 3G3FV has the following four control modes.
Open-loop vector control (without PG*) [Factory default]
Flux vector control (with PG)
V/f control (without PG)
V/f control (with PG)
*PG stands for “pulse generator” (encoder).
• Vector control is a method for removing interferences with magnetic flux and torque, and controlling
torque according to references. Current vector control independently controls magnetic flux current
and torque current by simultaneously controlling the motor’s primary current and its phases. This allows smooth rotation and high torque, along with accurate speed and torque control, at very low
speeds.
• Vector control can be replaced from the conventional V/f control system. If the motor parameter required for vector control is unknown, it can be set automatically with the auto-tuning function.
• The respective control modes are effective for the following applications:
Open-loop vector control (without PG): General variable speed drive
Flux vector control (with PG): Simple servo-drive, high-precision speed control, torque control
V/f control (without PG): Conventional Inverter control mode. Used for multiple drives.
V/f control (with PG): Simple speed feedback control
• The control characteristics for each mode are shown in the following table.
Vector controlV/f control

Speed control precision±0.2%±0.02%±2 to 3%±0.03%
Starting torque150% at 1 Hz150% at 0 Hz150% at 3 Hz
Auto-tuning Function
• This function is valid with vector control.
• The motor parameters are set automatically just by entering the motor’s rating plate value. This fea-
ture allows flux vector control to operate accurately with virtually any normal AC induction motor
regardless of the supplier.
Torque Control
• This function is valid with flux vector control (with PG).
• Torque is controlled by taking multi-function analog input signals as torque references.
• Switching is possible between torque control and speed control.
V/f Pattern Settings
• This function is valid for V/f control.
• Select a V/f pattern according to the application from among the 15 preset V/f patterns.
1-4
IntroductionChapter 1
• Custom V/f pattern can be set.
Frequency References
• The following five types of frequency references can be used to control the output frequency of the
Inverter.
Numeric input from the Digital Operator
Voltage input within a range from 0 to 10 V
Voltage input within a range from 0 to ±10 V (With minus voltage, rotation is in the opposite direc-
tion of the run command.)
Current input within a range from 4 to 20 mA
Input by Optional Card
The Inverter can be set to use any of the above types by designating it with parameters.
• A maximum of eight frequency references can be registered in the Inverter. Including inching, this
enables multi-step speed operation with up to nine speed steps via remote multi-step reference
inputs.
PID Control
• The Inverter has a PID control function, enabling easy follow-up control.
• Follow-up control is a control method in which the Inverter varies the output frequency to match the
feedback value from the sensor with the set target value.
• Follow-up control can be applied to a variety of control operations, depending on the contents
detected by the sensor.
• PID control is available for the following applications.
Speed control:With a speed sensor, such as a tacho-generator, the Inverter regulates the
rotation speed of the motor regardless of the load of the motor or synchronizes the rotation speed of the motor with that of another motor.
Pressure control:With a pressure sensor, the Inverter performs constant pressure control.
Flow-rate control:By sensing the flow rate of a fluid, the Inverter performs precise flow-rate
control.
Temperature control: With a temperature sensor, the Inverter performs temperature control by
fan speed.
Zero-servo Control
• This function is valid with vector control (with PG).
• Even at a motor speed of zero (0 Hz), a torque of 150% of the motor’s rated torque can be generated
and the average servomotor holding power (stopping power) can be obtained.
Speed Control By Feedback
• This function is valid with PG.
• An optional PG Speed Control Card be used to enable feedback control for speeds, thereby improving
speed control accuracy.
1-5
IntroductionChapter 1
Dwell Function
• By holding the output frequency for a constant time during acceleration and deceleration, acceleration
and deceleration can be performed without stepping out even when driving a motor with a large startup load.
Low Noise (0.4- to 160-kW Models)
• The output transistor of the Inverter is an IGBT (insulated gate bipolar transistor). Using a sine-wave
PWM method with a high-frequency carrier, the motor does not generate metallic noise.
Monitor Function
• The following items can be monitored with the Digital Operator.
Frequency reference, output frequency, output current, motor speed, output voltage reference,
main-circuit DC voltage, output power, torque reference, status of input terminals, status of output
terminals, operating status, total operating time, software number, speed deviation value, PID feedback value, fault status, fault history, etc.
• All types of data can be monitored even with multi-function analog output.
Seven-language Digital Operator (from Software Ver. VSG101113)
• Application a s a global inverter is enabled by displays in Japanese, English, French, German, Italian,
Spanish, or Portuguese.
• The Digital Operator area utilizes a 16-character x 2-line liquid crystal display. Parameter setting items
and monitor display can be easily read in any of seven languages to operate the Inverter in a conversational style.
Harmonic Countermeasures (0.4- to 160-kW Models)
• DC reactors (optional) can be connected to 0.4- to 15-kW models.
• Models of 18.5 to 160 kW have a built-in DC reactor.
Parameter Hierarchy and Three Types of Access Levels
• The 3G3FV has a number of parameters for carrying out the various functions. These parameters are
classified into hierarchical levels to make them easier to use. The levels are as follows, from top to
bottom: Mode Group Function Parameter.

IntroductionChapter 1
• The 3G3FV allows the following three kinds of access levels to be set in order to further simplify parameter setting. (An access level is a range of parameters that can be set or referenced.)
Quick-start:Sets/reads parameters required for trial operation. [Factory setting]
Basic:Sets/reads parameters that are commonly used.
Advanced:Sets/reads all the parameters that can be used.
• In general, press the Enter Key to move from an upper to a lower level. This varies somewhat, however, according to the access level, as shown in the following diagram. For the Quick-start access level,
which has few parameters that can be set, pressing the Enter Key jumps directly to the Parameter
level; whereas for the Advanced access level, which has many, pressing the Enter Key first leads to
the Group level.

ID for U1-14.
This section describes the new functions and improvements for each software version.
Refer to Chapter 5 Basic Operation and Chapter 6 Advance Operation.
1-3-1Software Ver. VSG101040
CompoBus/D (DeviceNet) Communications Card
The CompoBus/D Communications Card can be used to connect the Inverter to a DeviceNet network.
The following function additions and improvements were made to support this new functionality.
CompoBus/D Addition to the Frequency Reference Selection (Parameter b1-01)
A function was added to Frequency Reference Selection so that the Inverter frequency reference can
be input via DeviceNet communications.
CompoBus/D Addition to the Run Source Selection (Parameter b1-02)
A function was added to Run Source Selection so that the Inverter run command can be input via DeviceNet communications.
Communications External Fault Input (Parameters F9-01 to F9-03)
A function was added to support an external fault input from DeviceNet communications to stop the
Inverter when an error occurs. Sequence settings and operation designation for errors for the communications external fault input have been added.
Two-motor Switching Control
A function was added to enable switching control between two motors using one Inverter. The following
function additions were made to support this new functionality.
Control Mode Setting Second Motor (Parameter E3-01)
A control mode setting was added so that the second motor can be set to a different mode.
Note The control mode setting was limited to 0 (
was changed in system version VSG101043 to support all control modes 0 to 3.
V/f control without PG) or 2 (open-loop vector control), but
V/f Pattern Settings for Second Motor (Parameters E4-01 to E4-06)
V/f pattern settings were added so that the second motor can be set to a different pattern.
1-11
IntroductionChapter 1
Parameter Settings for Second Motor (Parameters E5-01 to E5-06)
Parameter settings were added so that different parameters can be set for the second motor.
Inverter Output Noise Reduction
The noise output by 400-V class Inverters was reduced to reduce the affect on peripheral devices and
conform to EN standards. The following function improvements were added to support noise reduction.
Default Setting Change for Carrier Frequency (Parameters C6-10 to C6-03)
The default carrier frequency setting for 400-V class Inverters was changed for the reduction of output
noise.
Inverter Overload Function Change (OL2 Detection)
The Inverter overload detection function was changed because the Inverter’s rated output current
would be reduced if it was set higher than the carrier frequency.
Note If an Inverter overload is detected before a motor overload (0L1), lower the Inverter’s carrier fre-
quency setting.
Operation Selection after Switching to Remote Mode (Parameter b1-07)
Operation can be switched between Digital Operator and the frequency reference (b1-01) and between
Digital Operator and the run command (b1-01) by setting the local/remote selection using the Digital
Operator’s operation mode selection key or multi-function inputs (H1-01 to H1-06). The new function
can be used to enable or disable run commands when switching between the two forms of operation.
Note If the run command is enabled when switching operation, the Inverter can start operation immedi-
ately after switching operation. You must take appropriate safety measures when using this function.
PG Disconnection Detection (PGO) Detection Time Setting (Parameter
F1-14)
A setting for PG disconnection (PGO) was added so that the detection time can be adjusted.
New Functions for Multi-function Inputs 1 to 6 (H1-01 to H1-06)
The following functions were added to the multi-function inputs.
• Sample/hold function for the analog frequency reference (setting: 1E)
• PID control integral reset (setting: 30)
Constant Output Area Settings for Flux Vector Control (E1-11 to E1-13)
Settings were added to enable controlling V/f characteristics to compensate voltage increases caused
by motor impedance when special motors, such as constant power-output motors and machine tool
shaft motors, are used in the constant output area.
Vector Control Adjustment Settings (C3-05, C5-08, C8-09, C8-30)
Adjustment functions were added for vector control.
The following functions were added for DeviceNet communications using a CompoBus/D Communications Card.
Network Reference/Network Control Support (CompoBus/D Communications
Remote I/O)
A function was added to switch between inputting the Inverter frequency reference and a run command
using CompoBus/D communications from remote I/O. The Network Reference Bit can be turned ON
and OFF to switch between the method set for the frequency reference selection (b1-01) and a frequency reference from communications. In the same way, the Network Control Bit can be turned ON
and OFF to switch between the method set for the run source selection (b1-02) and a run command
from communications.
Selection of Operation for Communications Errors (Parameter F9-06)
A setting was added to select the operation of the Inverter when a communications error is detected.
The selection can be made according to the application, e.g., a deceleration stop, free-run stop, continuing operation, etc.
Torque Limit/Torque Reference Operation Selection via Communications
(Parameter F9-05)
A function was added to set the torque limit and torque reference (for torque control) from communications. This enables controlling torque operation from communications when the vector with PG control
mode is used.
Note The CompoBus/D Communications Card does not support the torque limit/torque reference func-
tion. Leave this function disabled.
V/f Control with PG and Flux Vector Control for Two-motor Switching
Control (Parameter E3-01)
Settings were added for V/f Control with PG and Flux V ector Control to the control modes for the second
motor, enabling feedback control of 2 motors with 1 Inverter.
Note 1. Wiring for the pulse generator or encoder must be switched between the two motors.
Note 2. Use a pulse generator with the same specifications for both motors. (There is only one group
of parameters for the pulse generator.)
Motor Parameter Autotuning (Parameter C8-30)
An autotuning function was added to autotune the motor parameters for special motors.
Improvements in the current detector for vector control and in the responsiveness of current control
have greatly reduced torque ripple. This greatly reduces the low-speed inconsistencies for the 3G3FV
Series.
Better Motor Speed Control Accuracy (Parameter C3-06)
Previously the motor speed control accuracy for vector control was greatly reduced when the limit of
Inverter’s voltage output was approached (a voltage greater than that of the input power supply cannot
be output). If the new output voltage control method is used, the output voltage will be controlled so that
the limit will not be reached, thus maintaining speed accuracy. The linear characteristic of torque control
has also been improved.
Note The current may increase by about 10% when this function is used. Be sure to select an Inverter
with ample output current capacity.
Improved Motor Parameter Autotuning
A new method has been added for autotuning to produce greater accuracy.
Improved PID Control
Additions have been made to PID control to increase the range of possible applications.
PID Control Reverse Characteristics (Parameter b5-09)
Previously, only positive characteristic PID control, in which the feedback value increases when the
Inverter’s output frequency increases, was possible. In addition to this, reverse characteristic PID control is now possible, in which the feedback value decreases when the Inverter’s output frequency
increases.
Frequency Reference + PID Control (Parameters b5-01 and b5-10)
A control method using the frequency reference and PID control has been added between the previous
frequency reference or PID control. This is ideal for applications in which the target speed is set, but fine
adjustments need to be made with PID control (such as tension control).
Reverse Motor Control for PID Control (Parameter b5-11)
Motor rotation in only one direction was possible for previous PID control, but a reverse control setting
has been added to produce rotation in the reverse direction when the PID control result is negative.
1-14
IntroductionChapter 1
Feedback Loss Detection for PID Control (Parameters b5-12 to b5-14)
A function has been added to detect the loss of the feedback signal (e.g., as a result of line disconnection) and specify the operation when an error is detected.
PID Control Target Value Added to Multi-function Inputs (Parameters H3-05 and
H3-09)
A function was added so that both the analog frequency reference and the PID control target value can
be input as analog signals for frequency reference + PID control.
PID Integral Hold Added to Multi-function Inputs (Parameters H1-01 to H1-06)
A function was added to hold the the calculated integral value for PID control.
Jump Frequencies Added to PID Control (Parameters d3-01 to d3-04)
The setting disabled frequencies (jump frequencies) have been enabled for PID control. This function
can be used to avoid frequency ranges that cause machine vibration during PID control.
Motor Startup Responsiveness Improved
Compensation functions have been added to ensure faster motor startup.
Startup Torque Compensation Function for Open-loop Vector Control (Parameters
C4-03 to C4-05)
A startup torque compensation function has been added to ensure faster startup for open-loop vector
control. If this function is used, high torque can be output immediately after startup to enable better control of lifting and lowering operations for large machines with high friction or cranes.
Note This function cannot be used during regenerative condition or when using a second motor.
Magnetic Flex Compensation (Parameter b2-08)
Large-capacity motors have large electrical constants, and time is required to develop magnetic flex in
the motor after power has been turned ON. To improve this situation, a magnetic flex compensation
function has been added to the startup DC braking function, enabling magnetic flex to be built up in the
motor during DC braking.
Braking Function with Stall Prevention during Deceleration (Parameter
L3-04)
Even if regenerative energy is handled using a Braking Resistor or Braking Resistor Unit, overvoltages
(OV) can be detected during rapid deceleration. A stall prevention function for deceleration has been
added to the braking function (regeneration processing) to limit voltages when main circuit overvoltages
are likely to be detected, thus enabling faster braking without overvoltage detection.
Inverter Overload (OL2) Protection Selection for Low-speed Operation
(Parameters L8-17 and L8-19)
An Inverter overload protection operation selection has been added to protect from overcurrent damage at low speeds. This function allows the best protection to be selected according to the application.
1-15
IntroductionChapter 1
Protection Setting for Motors for Vector Control (Parameter E1-02)
A special protection setting has been provided for vector-control motors, which have high resistance to
overloads even at low speeds.
Bias Function for Analog Monitor Cards (Parameters F4-05 and F4-06)
A bias function has been added to the analog output from Analog Monitor Cards to enable adjusting the
offset voltage.
NC Contact Emergency Stop Function for Multi-function Inputs
(Parameters d3-01 to d3-04)
An NC contact emergency stop function has been added to the previous NO function.
Bias Function for Reverse Motor Control for Multi-function Inputs
(Parameters H3-05 and H3-09)
A function has been added for reverse motor operation by establishing a frequency bias 2 (setting: D)
for the multi-function inputs that causes reverse operation when the sum of the bias values is negative.
Run Command Selection Outside of Drive Mode (Parameter b1-08)
A function has been added to enable or disable run command inputs in mode other than Drive Mode,
e.g., Program Mode or Initialize Mode.
Note If this function is used, a run command can be input and Inverter operation stared even when
adjusting parameters in Program Mode. Proper safety measures must be taken to prevent dangerous situations.
Motor Core Loss Adjustment for Torque Compensation (Parameter
E2-10)
A motor core loss setting has been added to enable fine adjustment of torque compensation (totally
automatic torque boast) in V/f control without PG and V/f control with PG control modes.
Changes in Default Settings and Setting Ranges
The defaults and setting ranges for the following parameters have been changed for applications.
Cumulative Operation Time Display Change (Parameter o2-07)
Previously 0 was display when the default value was set for the cumulative operation time, but this has
been changed to display the current cumulative operation time as the default.

Wiring on the Input Side of the Main Circuit
Installing a Molded-case Circuit Breaker
Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a molded case
circuit breaker (MCCB) suitable to the Inverter.
• Install one wiring circuit breaker per Inverter.
• Choose an MCCB with a capacity of 1.5 to 2 times the Inverter’s rated current.
• For the MCCB’s time characteristics, be sure to consider the Inverter’s overload protection (one min-
ute at 150% of the rated output current).
• If the MCCB is to be used in common among multiple Inverters, or other devices, set up a sequence
such that the power supply will be turned OFF by a fault output, as shown in the following diagram.

Fault output (NC)

Note Use a 400/200 V transformer for a 400-V model.
Installing a Ground Fault Interrupter
Inverter outputs use high-speed switching, so high-frequency leakage current is generated.
In general, a leakage current of approximately 100 mA will occur for each Inverter (when the power
cable is 1 m) and approximately 5 mA for each additional meter of power cable.
Therefore, at the power supply input area, use a special-purpose breaker for Inverters, which detects
only the leakage current in the frequency range that is hazardous to humans and excludes high-frequency leakage current.
• For the special-purpose breaker for Inverters, choose a ground fault interrupter with a sensitivity
amperage of at least 10 mA per Inverter.
• When using a general leakage breaker , choose a ground fault interrupter with a sensitivity amperage
of 200 mA or more per Inverter and with an operating time of 0.1 s or more.
2-28
InstallationChapter 2
Installing a Magnetic Contactor
If the power supply of the main circuit is to be shut off because of the sequence, a magnetic contactor
can be used instead of a molded-case circuit breaker.
When a magnetic contactor is installed on the primary side of the main circuit to stop a load forcibly,
however, the regenerative braking does not work and the load coasts to a stop.
• A load can be started and stopped by opening and closing the magnetic contactor on the primary side.
Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break
down. To maintain the service life of the Inverter’s internal relays and electrolytic capacitors, it is recommended that this operation be performed no more than once every 30 minutes.
• When the Inverter is operated with the Digital Operator, automatic operation cannot be performed
after recovery from a power interruption.
• When using the Braking Resistor Unit, be sure to arrange a sequence in which the thermal relay of the
Unit turns the magnetic contactor OFF.
Connecting Input Power Supply to the Terminal Block
Input power supply can be connected to any terminal on the terminal block because the phase
sequence of input power supply is irrelevant to the phase sequence (R/L1, S/L2, and T/L3).
Installing an AC Reactor
If the Inverter is connected to a large-capacity power transformer (660 kW or more) or the phase
advance capacitor is switched, an excessive peak current may flow through the input power circuit,
causing the converter unit to break down.
To prevent this, install an optional AC reactor on the input side of the Inverter.
This also improves the power factor on the power supply side.
Installing a Surge Absorber
Always use a surge absorber or diode for the inductive loads near the Inverter. These inductive loads
include magnetic contactors, electromagnetic relays, solenoid valves, solenoid, and magnetic brakes.
2-29
InstallationChapter 2
Installing a Noise Filter on the Power Supply Side
The Inverter’s outputs utilize high-speed switching, so noise may be transmitted from the Inverter to th e
power line and adversely affect other devices in the vicinity. It is recommended that a Noise Filter be
installed at the Power Supply to minimize this noise transmission. Conversely, noise can also be reduced from the power line to the Inverter.
Note Use a noise filter designed for Inverters. A general-purpose noise filter will be less effective and
may not reduce noise.
Calculating the Inverter Input Power Supply Capacity
The following formula can generally be used to calculate the input power supply capacity for the
Inverter. Always select an Inverter with more than sufficient capacity.
Input power supply capacity [kVA] =
Motor output [kW]/(Motor efficiency x Inverter efficiency x Inverter input power factor)
Normal motor efficiency = 0.8, Normal inverter efficiency = 0.9, Inverter input power factor = 0.65 to 0.9
Note The Inverter’s input power factor will vary with the impedance of the power supply facilities. Use
0.9 when using an AC reactor and 0.65 when not using an AC reactor.
For the input current, divide the input power supply capacity by the input voltage. Assuming the Inverter’s resistance to overloads to be 150%, the calculated value can be multiplied by 1.5.
Example for 3-phase 200 V: 1.5 x input power supply capacity/(p3 x 200 V)
Example for single-phase 200 V: 1.5 x input power supply capacity/200 V
Wiring on the Output Side of Main Circuit
Connecting the Terminal Block to the Load
Connect output terminals T1 (U), T2 (V), and T3 (W) to motor lead wires T1 (U), T2 (V), and T3 (W),
respectively . Check that the motor rotates forward with the forward command. Switch over any two of
the output terminals to each other and reconnect if the motor rotates in reverse with the forward command.
2-30
InstallationChapter 2
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals T1 (U), T2 (V), and T3 (W). If voltage is applied to the
output terminals, the internal circuit of the Inverter will be damaged.
Never Short or Ground Output Terminals
If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Also, be careful not to
short the output wires.
Do Not Use a Phase Advancing Capacitor or Noise Filter
Never to connect a phase advance capacitor or LC/RC noise filter to the output circuit. Doing so may
result in damage to the Inverter or cause other parts to burn.
Do Not Use an Electromagnetic Switch or Magnetic Contactor
Do not connect an electromagnetic switch or magnetic contactor to the output circuit. If a load is connected to the Inverter during running, an inrush current will actuate the overcurrent protective circuit in
the Inverter.
Installing a Thermal Relay
This Inverter has an electronic thermal protection function to protect the motor from overheating. If,
however, more than one motor is operated with one Inverter or multi-polar motor is used, always install a
thermal relay (THR) between the Inverter and the motor and set n033 to 0 (no thermal protection).
In this case, program the sequence so that the magnetic contactor on the input side of the main circuit is
turned off by the contact of the thermal relay.
Installing a Noise Filter on Output Side
Connect a noise filter to the output side of the Inverter to reduce radio noise and induction noise.

Countermeasures Against Induction Noise
As described previously, a noise filter can be used to prevent induction noise from being generated on
the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent induction
noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces induction
noise.

Countermeasures Against Radio Interference
Radio noise is generated from the Inverter as well as the input and output lines. To reduce radio noise,
install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel
box. The cable between the Inverter and the motor should be as short as possible.

Cable Length between Inverter and Motor
As the cable length between the Inverter and the motor is increased, the floating capacity between the
Inverter outputs and the ground is increased proportionally. The increase in floating capacity at the Inverter outputs causes the high-frequency leakage current to increase, and this may adversely affect
peripheral devices and the current detector in the Inverter’s output section. To prevent this from occurring, use a cable of no more than 100 meters between the Inverter and the motor. If the cable must be
longer than 100 meters, take measures to reduce the floating capacity by not wiring in metallic ducts, by
using a separate cable for each phase, and so on.
Also adjust the carrier frequency according to the cable length between the Inverter and the motor, as
shown in the table below.
Note The carrier frequency setting range varies depending on the Inverter capacity.
200-V class, 18.5 kW max.; 400-V class, 30 kW max.: 0.4 to 15.0 kHz
200-V class, 22 to 75 kW; 400-V class, 37 to 160 kW: 0.4 to 10.0 kHz
400-V class, 185 to 300 kW:0.4 to 2.5 kHz
Single-phase Motors Cannot Be Used
The Inverter is not suited for the variable speed control of single-phase motors.
Single-phase motors are either capacitor start motors or split-phase start motors. (The method for de-
termining rotation direction at startup is different.) If a capacitor start motor is used, the capacitor may be
damaged by a sudden electric discharge caused by Inverter output. If a split-phase start motor is used,
the starting coil may burn because the centrifugal switch does not operate.
Ground Wiring
• Always use the ground terminal of the 200-V Inverter with a ground resistance of less than 100 Ω and
that of the 400-V Inverter with a ground resistance of less than 10 Ω.
• Do not share the ground wire with other devices such as welding machines or power tools.
• Always use a ground wire that complies with technical standards on electrical equipment and mini-
mize the length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode
and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
• When using more than one Inverter, be careful not to loop the ground wire.

Countermeasures against Harmonics
With the continuing development of electronics, the generation of harmonics from industrial machines
has been causing problems recently. Refer to the following for the definition of harmonics (i.e., harmonic
currents with voltages) and countermeasures against the generation of harmonics from the Inverter.
Harmonics (Harmonic Currents with Voltages)
• Definition
Harmonics consist of electric power produced from AC power and alternating at frequencies that are
integral multiples of the frequency of the AC power.
The following are the harmonic frequencies of a 60- or 50-Hz commercial power supply.
Second harmonic:120 (100) Hz
Third harmonic:180 (150) Hz
Second harmonic (120 Hz)
Basic frequency
(60 Hz)
Third harmonic (180 Hz)
• Problems Caused by Harmonics Generation
The waveform of the commercial power supply will be distorted if the commercial power supply contains excessive harmonics.
Machines with such a commercial power supply will malfunction or generate excessive heat.
Third harmonic (180 Hz)Basic frequency (60 Hz)
Distorted current
waveform
Causes of Harmonics Generation
• Usually, electric machines have built-in circuitry that converts commercial AC power supply into DC
power. Such AC power, however, contains harmonics due to the dif ference in current flow between AC
and DC.
• Obtaining DC from AC using Rectifiers and Capacitors
DC voltage is obtained by converting AC voltage into a pulsating one-side voltage with rectifiers and
smoothing the pulsating one-side voltage with capacitors. Such AC current, however, contains harmonics.
2-34
InstallationChapter 2
• Inverter
The Inverter as well as normal electric machines has an input current containing harmonics because
the Inverter converts AC into DC.
The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output
current of the Inverter is higher than that of any other electric machine.

Countermeasures with Reactors against Harmonics Generation
• DC/AC Reactors
The DC reactor and AC reactor suppress harmonics and currents that change suddenly and greatly.
The DC reactor suppresses harmonics better than the AC reactor. The DC reactor used with the AC
reactor suppresses harmonics more effectively.
The input power factor of the Inverter is improved by suppressing the harmonics in the input current of
the Inverter.
Note 18.5- to 160-kW Inverters have a built-in DC reactor.
185- to 300-kW Inverters cannot use a DC reactor.
• Connection
Connect the DC reactor to the internal DC power supply of the Inverter after shutting off the power
supply to the Inverter and making sure that the charge indicator of the Inverter turns off.
WARNINGDo not touch the internal circuitry of the Inverter in operation, otherwise an electric
!
shock or a burn injury may occur.

Connecting the Braking Resistor
• Connect the braking resistor as shown in the following diagram.
• When using a Braking Resistor Unit, set L8-01 to “1” (i.e., overheating protection of the braking resis-
tor) and set L3-04 to “0” (i.e., no decelerating stall prevention) or “2” (i.e., braking with stall prevention).
Inverter
CautionThe braking resistor’s connection terminals are B1 and B2. Do not connect any other
!
terminals. Connecting any terminals other than B1 or B2 can cause the resistor to
overheat, resulting in damage to the equipment.

Connecting the Braking Resistor Unit and Braking Unit
• Connect the Braking Resistor Unit and Braking Unit to the Inverter as shown in the following diagrams.
• Set L8-01 to “0” (i.e., no overheating protection of the braking resistor) and L3-04 to “0” (i.e., no decel-
erating stall prevention) or “2” (i.e., braking with stall prevention) before using the Inverter with the
Braking Resistor Unit connected.
Note 1. Set L8-01 to “1” before operating the Inverter with the braking resistor without thermal relay
trip contacts.
Note 2. The Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by
the Inverter if L3-04 is set to “1” (i.e., decelerating stall prevention).
• To prevent the Unit from overheating, make a power supply sequence as shown below or connect the
thermal relay trip output of the Unit to the external fault input terminal of the Inverter to interrupt the
running of the Inverter.

2-2-5Wiring Control Circuit Terminals
A control signal line must be 50 m maximum and separated from power lines. The frequency reference must be input to the Inverter through twisted-pair wires.
Wire Size and Round Solderless Terminals
Use thick wires to prevent voltage drops if the wires are long.
Considerations When Wiring Control Circuit Terminals
• Wire control signal lines separately from the main circuit lines and other power lines.
• Wire control circuit terminals 9, 10, 18, 19, and 20 (contact outputs) separately from terminals 1 to 8,
21, 22, 23, 25, 26, 27, 33, and 11 to 17.
• Connect shielded wire to terminal 12(G).
• Insulate the shielded areas with tape to prevent contact with other signal lines and equipment.

2-2-6Installing and Wiring PG Speed Control Cards
PG Speed Control Cards are used for executing speed control using a pulse generator (PG). There are
four types of PG speed control, as shown below. Select the type that fits the application and control
method.
3G3FV-PPGA2: A-phase (single) pulse input for open collector output, special-purpose V/f control
3G3FV-PPGB2: A/B-phase pulse input for open collector output, special-purpose vector control
3G3FV-PPGD2: A-phase (single) pulse input, line driver input, special-purpose V/f control
3G3FV-PPGX2: A/B/Z-phase pulse input, line driver input, special-purpose vector control
Installing a PG Speed Control Card
1. Turn off the main-circuit power supply, and leave it off for at least one minute before removing the
front cover of the Inverter (or at least three minutes for Inverters of 30 kW or more). Check to be sure
that the CHARGE light is OFF.
2. Insert the spacer (which is provided) into the spacer hole in the Inverter’s mounting base. For Inverters of 3.7 kW or less, there are two adjacent holes. Insert the spacer into the 7CN hole. The spacer
cannot be easily removed if inserted into the wrong hole. Be very careful to insert the spacer into the
correct hole, and in the proper direction.
3. Referring to the e n l a r ged illustration in the following diagram, align the PG Speed Control Card with
the catch position as shown by (1) and (2) and fit it precisely to the Option-A connector. Then pass
the spacer through the spacer hole at the Card. (Refer to illustration A.) Check to be sure that it is
precisely aligned with the 4CN position, and snap it into the proper position.

Selecting the Number of PG (Encoder) Pulses
3G3FV-PPGA2/-PPGB2
• The maximum response frequency is 30 kHz.
• Taking into consideration the encoder pulse deviation (phase difference: 90 ±45°) and the waveform
when the cable is long, select a smaller number of pulses than the ones shown in the following table.
Motor’s maximum speed (r/min)1,8001,500900
Number of encoder pulses (p/r)5006001,00
Maximum encoder frequency (kHz)151515
3G3FV-PPGD2/-PPGX2
• The maximum response frequency is 300 kHz.
• When the encoder pulse deviation (phase difference: 90 ±45°) is taken into consideration, the number
of encoder pulses can be calculated by means of the following formula:
60 x maximum response frequency (300,000 Hz)
Number of encoder pulses [p/r]
• If the motor’s maximum speed is less than 4,000 r/min, an encoder of 1,000 to 2,000 p/r is recommended. Even if an encoder with higher than required resolution is selected, it will not improve the
speed control range or precision.

3-2Modes
This section describes the 3G3FV’s various parameter setting and monitoring modes.
Inverter Modes
• The SYSDRIVE 3G3FV Inverter’s parameters and monitoring functions have been organized in
groups, so it is easier to make settings and read data. These function groups are known as modes.
• The 3G3FV is equipped with 5 modes, as shown in the following table.
ModePrimary function(s)
Operation modeThe Inverter can be run in this mode.
Use this mode when monitoring values such as frequency references or output
current, displaying fault information, or displaying the fault history.
Initialize modeUse this mode when selecting the language displayed on the Digital Operator,
selecting the access level for setting/reading parameters, selecting the control mode,
or initializing the parameters.
Program modeUse this mode when setting/reading the parameters required for operation. The
program-mode functions are subdivided into the following groups:
Application:Operation mode selection, DC control, speed search, etc.
Tuning:Acceleration/deceleration times, S-curve characteristics, carrier
frequencies, etc.
Reference:Settings related to frequency control
Motor:V/f characteristics and motor parameters
Option:Settings for Optional Cards
Terminal:Settings for sequential I/O and analog I/O
Protection:Settings for the motor and inverter protection functions
Operator:Selects the Digital Operator’s display and key functions

Monitoring at Startup
• In operation mode, the frequency reference, output frequency, output current, and output voltage can
be monitored immediately if the default settings are being used. One of these four values, the output
voltage, can be changed to a different value. When a value other than the output voltage is to be monitored, set that value’s number in parameter o1-01 (user monitor selection).
• When the power is turned on, the frequency reference will appear in the Unit’s data display if the default settings are being used. Any one of the four values monitored at startup (frequency reference,
output frequency , output current, or the value set in parameter o1-01) can be selected to appear when
the power is turned on. The value that appears at startup is determined by parameter o1-02 (PowerOn Monitor).
• Parameters o1-01 and o1-02 can be changed in the Basic or Advanced access levels. These parameters can be changed during operation.
User Monitor Selection (Parameter o1-01)
Use parameter o1-01 to select the values that will be monitored at startup.
Use the last two digits from the “U1 Monitor” list (U1-) to select a value. For example, the torque
reference is U1-09, so input 9 to select the torque reference.

Power-On Monitor (Parameter o1-02)
Use parameter o1-02 to indicate which value will be displayed when the Unit is started.
A setting of 1 indicates the frequency reference, 2 indicates the output frequency , 3 indicates the output
current, and 4 indicates the value set in parameter o1-01.
