Introduction Chapter 1

1-3

H Energy-saving Operation

• The rotation speed of a three-phase induction motor does not decrease when the supply voltage drops

if the motor has a light load. The 3G3HV Inverter in energy-saving operation automatically de

tects

the current consumption of the motor connected to the Inverter

, estimates its load, and drops the

output voltage, thus saving the power consumption of the motor efficiently.

• Use

the auto-tuning function of the Inverter in energy-saving mode to reduce the power consumption

of the motor most efficiently if the ratings of the motor are unknown.

• The Inverter in energy-saving mode is ideal for the following applications.

S Rotation control of fans and blowers S Flow control of pumps S Control of machines with variable loads, such as metal-working machines, wood-working ma-

chines, and food-processing machines

S Control of machines that mainly operate with light loads

H PID Control

• The Inverter has a PID control function, thus performing follow-up control with ease.

• Follow-up control is a control method in which the Inverter uses a sensor and senses the rotation

speed of the motor and changes the output frequency to control the rotation speed of the motor.

• Follow-up control can be applied to a variety of control operations.

• PID control is ideal for the following applications.

S Speed control: With a speed sensor, such as a tachometric generator, the Inverter regu-

lates

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.

S Pressure control: With a pressure sensor, the Inverter performs constant pressure control. S Current control: With a current sensor, the Inverter performs precise current control. S Temperature control: With

a temperature sensor and fan,

the Inverter performs temperature con

trol.

H Frequency Reference

• The

following three types of frequency references

are possible to control the output frequency of the

Inverter.

S Numeric input from the Digital Operator of the Inverter S Voltage input within a range from 0 to 10 V S Current input within a range from 4 to 20 mA

The Inverter can use one of the above if it is designated with parameters.

• A

maximum of four frequency references can be registered with the Inverter

. With remote multi-step

input, the Inverter can be in multi-step speed operation with a maximum of four speed steps.

H Frequency Jump

• The

frequency jump function prevents the Inverter from generating any frequency that causes the ma

chine to resonate.

Introduction Chapter 1

1-4

H Acceleration/Deceleration Time Settings

• The

acceleration time and deceleration time of the Inverter can be set independently within a range of

0.0 to 3,600 s.

• Two

acceleration times and two deceleration times can be

set with the Inverter

, any of which can be

selected with remote output.

H V/f Settings

• Select a V/f pattern out of the 15 V/f patterns preset with the Inverter according to the application.

• An optional V/f pattern can be set with the Inverter.

H Monitor Function

• The following items can be monitored with the Digital Operator.

Frequency

reference, output frequency

, output current, output voltage, DC voltage, output power

, status of input terminals, inverter status, power interruption error, PROM number, total operating time, and PID feedback value

H Low Noise (3.7- 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.

H High Torque at Low Output Frequency Range

• A

torque rate of 150% can be achieved even in a low

speed range where output frequency is only 3 Hz.

H Automatic Torque Boost

• The

Inverter automatically adjusts the output according to the required torque of the motor that is

rotat

ing at constant or accelerative speed, thus ensuring the powerful rotation of the motor.

H Harmonic Countermeasures (3.7- to 160-kW Models)

• DC reactors (optional) can be connected to 3.7- to 15-kW models.

• Models of 18.5- to 160-kW have a built-in DC reactor and also employ 12-pulse rectification, which

suppresses harmonics better than a reactor.

1-3 Additional Functions

New functions have been added to the following versions, for which production was started in April 1997.

3.7 to 15-kW models: Software version S2011 (VSP102011) or later

18.5 to 55-kW models: Software version S3012 (VSP103012) or later

Note:

The software version can be confirmed by viewing the 4-digit PROM number with the monitor function. This number is set to the number of the software version. The

functions that have been added with these versions and outlines of these functions

are given below. For details of the functions, refer to

Section 4 Operation

H Independent Initialization for Motor Rotation Direction

Although

the functionality of the forward/reverse rotation selection parameter (n005) itself has not been

changed,

with new models it will not be initialized when the parameter write prohibit selection/parame

ter initialization parameter (n001) is set to 6 or 7.

H V/f Default Settings Changed (Inverters of 55 kW or More)

The

default settings for V/f patterns have been changed for

the Inverters of 55 kW or more as shown

below.

Model Intermediate output frequency

voltage (n016)

Minimum output frequency

voltage (n018)

3G3HV-A2550 12.0 V 6.0 V 3G3HV-A4550 24.0 V 12.0 V

H Output Frequency Upper Limit Changed

The upper limit of the setting range for the output frequency upper limit parameter (n030) has been changed.

The addition of a slip compensation function means that frequencies greater than the maxi

mum frequency (n012) may occur (because the frequency reference is added to the compensation value).

For this reason, the upper limit of the setting range of the output frequency upper limit parameter

(n030) has been increased from 100% to 109%.

H PID Input Characteristic Selection Function (n039)

PID input characteristic selection input (set value: 27) function has been added to the multi-function

input 5 parameter (n039) that determines the function of terminal S6.

H Carrier Frequency Settings Increased (n050)

The setting 7.0 Hz (set value: 10) has been added to the available carrier frequency settings.

H Minimum Baseblock Time Setting Range Increased (n053)

The

setting range for the minimum baseblock time has been increased from the range 0.5 to 5.0 s to the

range 0.5 to10.0 s for increased motor responsiveness.

H Slip Compensation Function (n109 to n111)

function that compensates for motor slip, a characteristic of induction motors, has been added. Using

this

function, the amount of slip is estimated

from the output current of the Inverter

, and the output fre

Introduction Chapter 1

1-8

quency

is compensated accordingly

. By using the slip compensation function, speed fluctuations of the

load can be reduced more effectively than with previous models.

H Changing Parameters while Inverter is Running

is now possible to change some

parameters and, related to this, monitor and set the items in the bot

tom

two lines of

easy-setting indicators while the Inverter is running. Using this feature, set values for

some

parameters can be adjusted while monitoring operation. For details of which parameters can be

changed while the Inverter is running, refer to the parameter lists.

H Operation Selection at Digital Operator Interruption Function (n112)

function that detects communications errors between the Digital Operator and the Inverter itself, and

interrupts Inverter outputs has been added.

H Settable Detection Width (n113)

The

detection width of the optional frequency agreement and

the optical frequency detection can be set

with parameters. With previous models this setting was fixed.

H Operation Selection at Operation Mode Switching (Local/Remote

Switching) (n114)

Using

the Operation Mode Selection Key on the Digital Operator or operation mode selection input set using the multi-function input parameters (set value: 5), it is possible to switch between operation from the

Digital Operator and operation according

to the setting of the operation mode selection parameter (n002). A function that selects whether run signals input while the operation mode is switching are enabled or disabled after the mode has changed, has been added.

Note If

this setting is set to enable run commands, when the operation mode changes the Inverter will

start running immediately. Take steps to ensure safety for such operation.

Note Determining Wire Size

Determine

the wire size for

the main circuit so that line voltage drop is within 2% of the rated volt

age.

Line voltage drop is calculated as follows: Line voltage drop (V) = √3 x wire resistance (Ω/km) x wire length (m) x current (A) x 10

H Wiring on the Input Side of the Main Circuit

D 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.

3-phase/ Single-phase 200 V AC 3-phase 400 V AC

Power supply

Inverter

Fault output (NC)

(See note.)

Note Use a 400/200 V transformer for a 400-V model.

D 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.

Installation Chapter 2

2-22

D Installing a Magnetic Contactor

the power supply of the main circuit is to be shut of

f 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.

o maintain the service life of the Inverter’s internal

relays and electrolytic capacitors, it is rec

ommended 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.

D 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).

D 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.

D 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.

Installation Chapter 2

2-23

D 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 the 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 ef

fective and

may not reduce noise.

D Calculating the Inverter ’s Input Power Supply Capacity

The power supply capacity for the Inverter can be calculated in the way shown below. The value obtained should only be as a reference; allow for some degree of variation.

Input

power supply capacity (kV

A) = Motor output (kW)/(Motor ef

ficiency× Inverter ef

ficiency× Inverter input power factor) Motor efficiency = 0.8 (typ.) Inverter efficiency = 0.9 (typ.) Inverter input power factor = 0.65 to 0.9

Note The Inverter’s input power factor varies with the impedance. If an AC reactor is used, take the

value to be 0.9, and if an AC reactor is not used, take the value to be 0.65.

calculate the input current, divide the input power supply capacity obtained

above by the input volt

age.

The Inverter has an overload capacity of 150%, and so set to a value 1.5 times the result of this calculation. Example: 3-phase 200-V: 1.5 × Input power supply capacity/(√3 × 200 V)

Single-phase 200-V: 1.5 × Input power supply capacity/200 V

D Setting the Power Supply Voltage Short Pin (400-V Class Inverters of 18.5 kW or

More)

Set the power supply voltage short pin for 400-V Class Inverters with a capacity of 18.5 kW or more.

Short Pin Setting Procedure

1. Turn

OFF the power supply and wait for at least one minute (three minutes for

Inverters of 30 kW or

more) before removing the front panel.

Installation Chapter 2

2-24

2. Insert the short pin mounted on the board into the voltage connector nearest to the actual power supply voltage. The default setting is 440 V.

The following example shows board of a 400-V Class Inverter of 18.5 to 45 kW.

380 V 400/415 V 440 V 460 V

3. Put the front panel to its original position.

H Wiring on the Output Side of Main Circuit

D 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 com

mand.

D 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.

D Never Short or Ground Output Terminals

the output terminals are touched with bare hands or the output wires come into contact with the Invert

casing, an electric shock or grounding will occur

. This is extremely hazardous. Also, be careful not to

short the output wires.

D 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.

D Do Not Use an Electromagnetic Switch or Magnetic Contactor

not connect an electromagnetic switch or magnetic contactor to the output circuit. If a load is con

nected

to the Inverter during running, an inrush current will actuate the overcurrent protective circuit in

the Inverter.

Installation Chapter 2

2-25

D 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.

D 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.

o reduce radio noise,

install

box. The cable between the Inverter and the motor should be as short as possible.

3G3HV

D Cable Length between Inverter and Motor

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 In

verter 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. T

o prevent this from occur

ring,

use a cable of no more than 100 meters between the Inverter and the motor

. If the cable must

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.

Cable length 50 m max. 100 m max. More than 100 m

Carrier frequency (n050) 15 kHz max (6 max.) 10 kHz max. (4 max.) 5 kHz max. (2 max.)

Note The carrier frequency setting range varies depending on the Inverter capacity.

200-V class, 22 kW max.; 400-V class, 22 kW max.: 0.4 to 15.0 kHz 200-V class, 30 to 75 kW; 400-V class, 30 to 160 kW: 0.4 to 10.0 kHz 400-V class, 185 to 300 kW: 0.4 to 2.5 kHz

D 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 dif

ferent.) 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.

Installation Chapter 2

H 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 unsta

ble.

• When using more than one Inverter, be careful not to loop the ground wire.

H 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.

D 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

Basic frequency (60 Hz)

Second harmonic (120 Hz)

Third harmonic (180 Hz)

• Problems Caused by the Harmonics Generation

The

waveform

of commercial power supply will be distorted if the commercial power supply contains excessive harmonic currents. Machines with such a commercial power supply will malfunction or generate excessive heat.

Third harmonic (180 Hz)Basic frequency (60 Hz)

Distorted current waveform

D 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

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, however, contains harmonics.

Installation Chapter 2

2-29

• Inverter

The

Inverter as well as normal electric machines has an output 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.

Voltage

Current

Time

Rectified

Smoothed

A current flows into the capacitors. The current is different from the voltage in waveform.

D 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.

WARNING Do

not touch the internal circuitry of the Inverter in operation, otherwise an electric

shock or a burn injury may occur.

D Countermeasures with 12-pulse Rectification against Harmonics Generation

• 12-pulse Rectification

The

3G3HV

-series Inverter

with an output of 18.5 to 160 kW can employ 12-pulse rectification, which suppresses harmonics better than reactors. The 3G3HV-series Inverter with an output of 15 kW or less and 185 kW or more cannot employ 12-pulse rectification.

• Wiring Method

1. Terminals

L1 (R) and L1

1 (R1), L2 (S) and L21 (S1), and L3 (T) and L31 (T1) are short-circuited with

short

bars before shipping.

Be sure to remove the short bars when employing 12-pulse rectification,

otherwise the Inverter will break down.

Preparing for Operation Chapter 3

3-9

The same kind of switching is also possible with control circuit terminals set using the multi-function input parameters 1 to 5 (set value: 5).

Operation mode Description Contents

Remote Inverter operates according to control

signals from a higher level control system.

Run commands and frequency references determined by the setting of the operation mode selection parameter (n002).

Local Inverter operates alone in order to check

operation directly related to the Inverter.

Run commands: RUN and STOP/RESET Keys. Frequency reference: Value set with the Digital Operator.

Note Performs operation for a operation

mode selection parameter value (n002) of 0.

Note 1. The

operation mode will always be

Remote mode when power is supplied. Therefore, to start

operation

immediately after power is supplied, set n002 to the required settings in advance.

Note 2. If n002 is set to 0, there is no difference in the two modes. Note 3. Frequencies

set from the Digital Operator using the speed setting

will be entered in frequency reference parameters 1 to 4 (n025 to n028) or the inching frequency reference parameter (n029) regardless of whether the mode is Remote mode or Local mode.

Note 4. Multi-function

inputs 1 to 5 will be enabled regardless of whether the mode is Remote mode

Local mode. The following settings, however, will be disabled in Local mode.

S Reverse rotation/stop (2-wire sequence selection); Set value: 0 S Stop command (3-wire sequence selection); Set value: 1

Note 5. For

safety reasons, run signals input while changing

from Local mode to Remote mode are usually ignored. Input the run signal again after the mode has changed. It is possible, however,

to stop such run signals being ignored

by setting the Operation Selection at Operation

Mode

switching (Local/Remote switching) parameter (n1

14) to 1. If this setting is made, when

the

mode

changes from Local mode to Remote mode, the Inverter will start running immedi

ately. Take steps to ensure the safety of the system for such operation.

3-5 Applied Operation

3-5-1 Energy-saving Mode

The

Inverter in energy-saving mode will automatically save unnecessary power supply to the motor if the load is light and the motor is a standard motor or dedicated motor for inverters. The Inverter in energy-saving mode will estimate the load factor

of the motor from the

current

consumption of the motor

and controls the output voltage to supply only neces

sary

power if the load is light. Energy-saving mode is appropriate for loads with little fluc

tuation.

It is not appropriate for control that requires a response time of less than 50 ms.

The

longer the energy-saving time of the Inverter is, the more ef

fectively the power sup

plied

to the load is saved.

The power supplied to the load will be hardly saved if the load exceeds 70% of the rated output torque of the motor. The

Inverter in energy-saving mode cannot save

unnecessary power supply to special motors, such as spindle motors and submersible motor. Refer

to the following for the settings of the Inverter enabling it

to perform energy-saving

control.

H Energy-saving Control

The following are the energy-saving control steps of the Inverter.

1. The Inverter starts accelerating the motor normally. The Inverter does not perform energy-saving control while the Inverter is accelerating the motor.

2. The

Inverter will perform energy-saving control when the output frequency corresponds to the fre

quency specified by the frequency reference.

3. The Inverter calculates the ideal output voltage from the running condition of the Inverter and the energy-saving coefficient K2 set with n096.

4. The output voltage is changed to the ideal output voltage.

5. The

Inverter uses the auto-tuning function (search operation) to find the minimum output power that

the Inverter supplies to the motor. Auto-tuning function (search operation):

Finds

the minimum output power that the Inverter supplies to the motor by changing the output

volt

age with the auto-tuning voltage steps set with n101 and n102.

6. The

Inverter starts decelerating the motor normally

. The Inverter does not perform energy-saving

control while the Inverter is decelerating the motor.

Preparing for Operation Chapter 3

3-26

The

most ef

ficient input voltage imposed on the motor varies with the load factor of the motor

. The In

verter

in energy-saving mode calculates the ideal output voltage and adjusts

the ideal output voltage so

that the actual power supplied to the motor can be minimized.

3-5-2 PID Control

PID

(proportional, integral, and derivative) control is a method to control a

mechanical

system

by making the feedback values obtained from the mechanical system agree with the set point that has been preset. This method makes it possible to control a mechanical system that has dead time. The

Inverter is not suitable for PID

control that requires a response time of 50 ms or less.

Refer

to the following for examples of PID control that can be performed

by the Inverter

well as the operation of PID control in detail and the settings and adjustments of the

parameters.

H Examples of PID Control

Refer to the following for examples of PID control that can be performed by the Inverter.

Application Control Required sensor

Speed control The Inverter uses the feedback of speed data of the

mechanical system and makes the operation speed of the mechanical system agree with the set point.

can keep up with rapid feedback changes.

D PID Control

PID

control makes use of the merits of proportional

control, integral control, and derivative control to

perform ideal control.

H Types of PID Control

The

Inverter performs two types of PID control (i.e., derivative data PID

control and basic PID control).

The Inverter usually performs derivative data PID control.

D Derivative Data PID Control

Derivative

data PID control is a type of PID control which dif

ferentiates

the feedback of values and

keeps up with set point changes and control object changes.

PID Control Function Selection

Setting range 0, 1, and 2 Unit --- Default setting 0

Set Values

Set value Description

0 No PID control. 1 PID control with deviation derivative control. 2 PID control with feedback derivative control. 3 PID control with negative feedback characteristic control.

Note 1. Set n084 to 1, 2, or 3 to permit the Inverter to perform PID control. Note 2. Usually set n084 to 2 to change set points. Note 3. Set

n084 to

3 to perform PID control using the negative characteristic of the characteristic of

the

feedback value input from the sensor

. Using the negative characteristic means that [100%

–

feedback value] is used as the PID feedback value. This is ef

fective for negative characteris

tic control (control where the feedback value drops when the Inverter’s output frequency rises).

• If

n084 is set to 1 or 2, the method to input the set point will be determined by the

operation mode set

n085 Feedback Adjustment Gain

Setting range 0.00 to 10.00 Unit Times Default setting 1.00

Preparing for Operation Chapter 3

3-35

Set Values

• Set the feedback adjustment gain with n085.

• The

feedback of the FI terminal multiplied by the feedback adjustment gain will be the feedback adjust

ment gain data of the Inverter.

n086 Proportional Gain (P)

Setting range 0.0 to 10.0 Unit Times Default setting 1.0

n087 Integral Time (I)

Setting range 0.0 to 100.0 Unit s Default setting 10.0

n088 Derivative Time (D)

Setting range 0.00 to 1.00 Unit s Default setting 0.00

Set Values

• The parameters n086, n087, n088 adjust PID control response.

• Set

n086, n087, and n088 to optimum values by operating the mechanical system. Refer to

page

3-36,

PID Adjustments

for details.

• Proportional

control or integral control will not be performed if n086 or n087 is set to

0.0 and derivative

control will not be performed if n088 is set to 0.00.

n089 PID Offset Adjustment

Setting range –109 to 109 Unit % (Maximum

frequency ratio)

Default setting 100

Set Values

• The parameter n089 adjusts the PID control offset of the Inverter.

• The

Inverter adjusts the of

fset of the voltage used to determine the set point and the of

fset of analog

input to the FI terminal according to the value set with n089.

• Set

n089 so that the output frequency of the Inverter will be 0 Hz when the set point and feedback are

both zero.

n090 Integral Upper Limit

Setting range 0 to 109 Unit % (Maximum

frequency ratio)

Default setting 100

Set Values

• The upper limit of integral control quotients is set with n090.

• It is usually unnecessary to change the default-set value of n090.

• Set

n090 to a small value if the response of the Inverter may damage the

load or allow the motor to go

out of control when the load factor of the motor varies greatly.

• The feedback will not agree with set point if n090 is set to a value that is too small.

n091 PID Primary Delay Constant

Setting range 0.0 to 2.5 Unit s Default setting 0.0

Preparing for Operation Chapter 3

3-36

Set Values

• The parameter n091 works as a low-pass filter for the PID control output.

• It is usually not necessary to change the default-set value of n091.

• If

the friction factor of the mechanical system is large and the mechanical system

resonates, set n091

a value larger than the resonance frequency

, in which case, however

, the

PID response of the In

verter will be low.

n092 Feedback Loss Detection Selection

Setting range 0, 1 Unit --- Default setting 0

Set Values

Set value Description

0 Feedback loss is detected. 1 Feedback loss is not detected.

• By

setting n092 to 1, the Inverter determines that the feedback line is disconnected if the Inverter re

ceives a feedback value that is too low.

• The

Inverter will

have PID feedback loss output as multi-function output if the Inverter detects feed

back loss. Therefore, program a sequence to interrupt the operation of the Inverter.

n093 Feedback Loss Detection Level

Setting range 0 to 100 Unit % (Maximum

frequency ratio)

Default setting 0

n094 Feedback Loss Detection Time

Setting range 0.0 to 25.5 Unit s Default setting 1.0

Set Values

• Set feedback loss detection conditions with n093 and n094.

• Feedback

loss will be detected if the Inverter receives feedback values lower than the feedback loss

detection level set with n093 for the time set with n094.

• Set n093 to a value based on the maximum frequency set with n012 as 100%.

H PID Adjustments

D Step Response

The

parameter values used by the Inverter to perform PID control can be adjusted according to the step

response of the control object.

1. Step Response Waveform Take the following steps to measure the step response waveform of the control object.

a) Connect

the load in the same way as the connection of the load to the Inverter in normal

opera

tion. b) Set n084 to 0 so that the Inverter will not perform PID control. c) Minimize the acceleration time and input step frequency reference. d) Measure the response waveform of the feedback.

Preparing for Operation Chapter 3

3-37

Note Measure the response waveform so that the timing of the step input will be known.

2. Calculation of PID Parameters

S Draw a tangent line contacting with the steepest inclining point of the response waveform. S Measurement of R

Measure the gradient of the tangent line provided that the set point is 1.

S Measurement of L

Measure

the required time (seconds) between the origin and the point of intersection of the tan

gent line and time axis.

S Measurement of T

Measure

the required

time (seconds) between the point of intersection of the tangent line and time

axis and the point of intersection of the tangent line and set point line.

S PID Parameters

The following can be calculated from the R, L, and T values as “rules of thumb.”
