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 control V/f control
Without PG With PG Without PG With PG
Speed control range 1:100 1:1,000 1:40 1:40
Speed control precision ±0.2% ±0.02% ±2 to 3% ±0.03%
Starting torque 150% at 1 Hz 150% at 0 Hz 150% 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.

Introduction Chapter 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.

Introduction Chapter 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.
Level name Contents

Introduction Chapter 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.

1-3-1 Software 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)

1-11
Introduction Chapter 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.
