General safety and Operating Instructions for drive converters

in conformity with the Low-Voltage Directive 79/23/EEC

-

1. General In operation, drive converters, depending on their

degree of protection, may have live, uninsulated, and possibly also moving or rotating parts, as well as hot surfaces.

In case of inadmissible removal of the required covers,

or improper use, wrong installation or maloperation, there is the danger of serious personal injury and damage to property. For further information, see documentation. All operations serving transport, installation and commissioning as well as maintenance are to be carried out by skilled technical personnel. (Observe IEC 364 or CELEC HD 384 or DIN VDE 0100 and IEC 664 or DINNDE 0110 and national accident prevention rules!)

For the purposes of these basic safety instructions,

“skilled technical personnel” means persons who are familiar with the installation, mounting, commissioning and operation of the product and have the qualifications

needed for the performance of their functions.

2. Intended use Drlve converters are components designed for inclusion

in electrical installations or machinery.

In case of installation in machinery, commissioning of

the drive converter (i.e. the starting of normal operation) is prohibited until the machinery has been proved to conform to the provisions of the Directive 89/392/EEC

(Machinery Safety Directive - MSD). Account is to be

taken of EN 60204. Commissioning (i.e. the starting of normal operation) is

admissible only where conformity with the EMC

Directive (89/336/EEC) has been established.The drive

converters meet the requirements of the Low-Voltage Directive 73/23/EEC. They are subject to the

harmonized standards of the series prEN 50178/DIN

VDE 0160 in conjunction with EN 50439-1NDE 0660, part 500, and EN 60146lVDE 0558.

The technical data as well as information concerning the supply conditions shall be taken from the rating plate

and from the documentation and shall be strictly

observed.

3. Transport, storage

The instructions for transport, storage and proper use

shall be complied with.

The climatic conditions shall be in conformity with prEN

50178.

4. lnstallatlon The installation and cooling of the appliances shall be in

accordance with the specifications in the pertinent documentation.

The drive converters shall be protected against excessive strains. In particular, no components must be

bent or isolating distances altered in the course of transportation or handling. No cantact shall be made with electronic components and contacts. Drive

converters contain electrostatic sensitive components which are liable to damage through improper use.

Electric components must not be mechanically damaged

or destroyed (potential health risks).

5. Electrlcal connectlon

When working on live drlve converters, the applicable

national accident prevention rules (e.g. VB 4) must be

complied with. The electrical installation shall be carried out in

accordance with the relevant requirements (e.g. cross

sectlonal areas of conductors, fusing, PE connection).

For further information, see documentation.

Instructions for the installation in accordance with the EMC requirements, like screening, earthing, location of filters and wiring, are contained in the drive converter documentation. They must always be complied with, also for drive converters bearing a CE marking. Observance of the limit values required by EMC law is the responsibility of the manufacturer of the installation or machine.

6. Operation Installations, which include drive converters shall be

equipped with additional control and protective devices in accordance with the relevant applicable safety requirements, e.g. Act respecting technical equipment, accident prevention rules, etc. Changes to the drive converters by means of the operating software are admissible. After disconnection of the drive converter from the voltage supply, live applicance parts and power terminals must not be touched immediately because of possibly energized capacitors. In this respect, the corresponding signs and markings on the drive converter must be respected.

During operation, all covers and doors shall be kept

closed.

7. Maintenance and servicing

The manufacturer’s documentation shall be followed.

KEEP SAFETY INSTRUCTIONS IN A SAFE PLACE!

Please observe the product-specific safety and Operating Instructions stated in these Operating

Instructions.

Application

as directed

The 8200 series consists of electrical devices which are designed for application in industrial power installations.

The controllers are directed

-

as components for the control of variable

Speed

drives with

AC motors

-

for the installation into control cabinets or control boxes

-

as controllers for the installation of drive

Systems

The controllers comply with the

protection

requirements of the

EC Low-Voltage Directive. Drive Systems with 8600 controllers which are assembled

according to the requirements for CE-typical drive

Systems

(see

chapter

4.2.2) comply with the EC EMC Directive.

The CE-typical drive

Systems

with the 8600 controllers are

intended

-

for the Operation at public and non-public mains

-

for the application in industrial, commercial and residential areas

The CE-typical drive Systems are not suited for the connection to IT mains (mains without earth-potential reference)

because

of

the earth-potential reference of the RFI filter. The controllers are not appliances but directed as components

to be assembled into drive Systems for industrial use. The controllers themselves do not form machines for the

purpose of the EC Machinery Directive.

2.5 CE conformity

What is the purpose of EC directives?

EC directives are issued by the

European

Council and are intended for the determination of common technical requirements (harmonization) and cet-tification procedures within the

European

Community. At the moment, there are 21 EC directives of product

ranges.

The directives are or will be

conver-ted

to national laws of the member states. A certification issued by one member state is valid automatically without any

fut-ther

approval in all other member states. The texts of the directives are restricted to the essential

requirements. Technical details are or will be determined by

European

harmonized Standards.

What does the CE mark imply?

After a verification, the conformity to the EC directives is

certified

by

affixing a CE mark. Within the EC there are no commercial barriers

for a product with the CE mark. The enclosure of a conformity cet-tification is not necessary according to most directives.

Therefore, the customer is not able to appreciate

which

of the 21

EC directives applies to a product and

which

harmonized Standards

are considered in the conformity verification. A drive

controller

with the CE mark itself corresponds exclusively to

the Low-Voltage

Directive.

For the compliance with the EMC

Directive

only general recommendations have been issued so far.

The CE conformity of the installed

remains the

responsibility of the

User.

For the

installation

of CE-typical drive

Systems

(see page

26ff),

Lenze has already proved the CE

conformity to the EMC

Directive.

What is the aim of the EMC

Directive?

The EC

Directive

relating to

Electromagnetit

Compatibility is

effective

for “equipment”

which

may either

Cause electromagnetic

disturbances or be affected by such disturbances. The aim is the limitation of the generation of

electromagnetic

disturbances so that the Operation of radio and telecommunication

Systems

and other equipment is possible and that a suitable

immunity of the equipment against

electromagnetic

disturbances is

ensured so that the Operation

tan

be achieved.

What is the

objective

of the Low-Voltage

Directive?

The Low-Voltage

Directive

is

effective

for all electrical equipment

for use with a rated voltage between 50V and 1 OOOV AC and

between 75 and 1500V DC and

under

normal ambient conditions. The use of e.g. electrical equipment in explosive atmospheres and electrical

Parts

in passenger and goods lifts are excepted.

The

objective

of the Low-Voltage

Directive

is to ensure that

only

that electrical equipment

which

does not endanger the safety of man or

animals

is

placed

on the market. lt should

also be designed to

conserve

material

assets.

Handling

4.1

Mechanical installation

These frequency controllers must only be used as built-in units.

Install

the controller

vettically

with the terminal

Strips

at the

bottom.

Allow

a free space of

100mm

at the top and bottom. For the controllers 8612 . . . 8615 this free space must also be allowed at both sides. Ensure unimpeded Ventilation of cooling air.

If the cooling air contains pollutants (dust,

flakes,

grease,aggressive

gases ), which

may impair the controller

functions,

suitable preventive measures must be taken,

e.g.

separate air

duct,

installation of a

fiter,

regular

cleaning,

etc.

If the controller is permanently subjected to Vibration or shaking,

shock

absorbers may be necessary.

22

-

4.2

Electrical

installation

l The Controllers contain sensitive electrostatic compontents.

Priior

to assembly and Service operations in the area of the

controller connections, the

Personne1

must be free

of

electrostatic Charge. These persons

tan discharge

themselves by

touching

the PE

fixing screw or another grounded metal

part

in the control

cabinet.

l All control inputs and Outputs of the controller are mains-

isolated. The mains isolation has a

basic

insulation. The control

inputs and Outputs must be integrated into another

level

of

protection

against

direct

contact. Use insulated operating elements, connect the mechanical screw

fastener

of the

setpoint

potentiomenter (accessory kit)

with PE.

l Unused control inputs and Outputs must be protected with plugs

or the

covers

included in the delivery.

l When using current-operated protective equitpment:

-

The

controllers

are internally equipped with a mains rectifier.

As result, a DC-fault

current

may prevent the tripping of the

current-operated protective equipment after a short-circuit to frame.

Therefore, we recommend additional measures such as protective multiple

earthing

or universal-current sensitive

current-operated

e.1.c.b.

-

When dimensioning the tripping

current

of current-operated

e.1.c.b.

please observe, that the capacitive leakage currents

between

cable screens

and RFI

filters

may result in false

tripping.

l The regulations

about

the

minimum Cross section

of PE

conductors must be observed. The

Cross-section

of the PE

conductor must be at least as large as the

Cross section

of the

cable

connection.

l In the

case

of

condensation,

only connect the Controller vwhen

visible moisture has evaporated.

l Before first switching-on of the controller check whether there is

an

earth

fault at the output side, if so, remove it.

Earth

faults

which

occur

during

Operation will be detected, the controller will

be switched off and indicate the fault message

“OCl”.

l The internal

current

limitation

tan

be overloaded when

connecting or disconnecting the controller very often. With cyclic

mains connection, the Controller

tan

be switched on every 3

minutes.

l Replace

defective

fuses only with the specified type and when no voltage is applied. The controller remains live for up to 3 minutes after mains disconnection.

4.2.1 Motor protection

The units do not have a

full

motor protection.

For monitoring the motor temperature

PTCs

orthermal contacts

tan

be used.

The connection possibilities are shown on page 28. When using group drives, a motor protection relay is required for

each

motor.

When using motors which do not have a suitable insulation for controller Operation:

-

Connect motor filters for protection (see page 45).

Please contact your motor manufacturer.

Please note:

These frequency controllers generate an output frequency of up to 480 Hz when set correspondingly. The connection of a motor which is not suitable for this frequency may result in a hazardous overspeed.

4.2.2 Installation in compliance with EMC

l Lenze has built up typical drives with these controllers and has

verified the conformity. In the following this

System

is called

“CE-typical drive system”.

If

you observe the

pat-tially

easy measures for the

installation

of

CE-typical drive

System,

the controller will not

Cause

any EMC

Problems

and you

tan

be sure to comply with the EMC

Directive.

l The following configurations

tan

now be selected by the

User:

-

The user himself

tan

determine the

System

components and

their integration into the drive

System

and is then held

responsible for the conformity of the drive.

-

The user

tan

select the CE-typical drive

System

for which

the manufacturer has already proved the conformity.

For deviating installations, e.g.

-

use of unscreened cables,

-

use of group filters instead of the assigned RFI filters,

-

without mains

Choke

the conformity to the CE-EMC Directives requires a check of the

machine

or

System

regarding the EMC limit values.

The user of the machine is responsible for the compliance with the EMC

Directive.

4.2.3 CE-typical drive

System

Components of the CE-typical drive

sytem

Controller,

RFI

filter and mains

Choke

are mounted on one assembly board. The

System

components are

functionally

wired according to the

chapter

5, section: Planning of the Operating Instructions.

Installation of CE-typical drive Systems

The

electromagnetic

compatibility of a

machine

depends on the

method and accuracy of the

installation. Special care

must be

taken of:

l filters,

l

screens

and

l grounding.

Filters

Only use suitable mains filters and mains Chokes.

Mains filters reduce impermissible high-frequency disturbances to a perrnissible value. Mains

Chokes

reduce low-frequency disturbances, especially those

caused

by long motor cables.

Motor cables

which

are longer than 50 m must be protected

additionally (motor filter or sine filter).

Screens

All cables from and to

t3e controller

must be screened.

Lenze

System

cables meet these requirements.

Ensure that the motor

cable

is laid separately from the other cables

(Signal

cables and mains cables). Mains input and motor output

must not be connected to one terminal

Strip.

Lay cables as

close

as possible to the reference potential. Dangling

cables are like antennas.

Grounding

Ground

all metall-conductive components

(controllers,

mains filters,

mains Chokes) using suitable cables from a

central Point

(PE bar).

Maintain the min.

Cross sections

prescribed in the safety

regulations. For EMC, the

surface

of the contact is important, not

the

Cross

section.

lmue

25

Installation

l Connect the Controller, mains fitter, and mains

Choke

to the

grounded mounting plate. Zinc-coated mounting plates

allow

a

permanent contact. If the mounting plates are painted, the paint

must be removed in

every case.

9

When using several mounting plates they

must

be connected

with as large surface as possible

(e-g.

using

topper

bands).

l Connect the

Screen

of the motor cable to the

Screen

connection of the Controller and to the mounting plate of a surface as large as possible. We recommend to use ground

clamps

on bare

metal mounting

surfaces

to connect the

Screen

to the mounting

plate with as large surface as possible,

-

screened cable

urface

If contactors, motor

protection

switches or terminals are located in the motor cable, the screens of the connected cables must also be connected to the mounting plate with as

[arge

surface

as possible. PE and the

Screen

should be connected in the motorterminal

box.

Metal

cable glands at the motor

terminaJ

box ensure a

connection of the

Screen

and the motor housing with as large a

surface as possible.

If

the mains cable between mains filter and Controller is longer

than 0.3 m, the cable must be screened. Connect the

Screen

of

the mains cable directly to the Controller

moduie

and to the mains filter and connect it to the mounting plate with as large as possible surface.

When using a brake resistor, the

Screen

of the brake resistor

cable

must

be directly connected to the

controller

and the brake

resistor and it must be connected to the mounting platte with a

surface

as large as possible.

The control cables must be screened. Digital

contra1

cables

must be screened at both ends. Connect the screens of the

contra! cables to the

Screen

connections of the Controllers

leaving as

little

unscreened cable as possible.

When using the Controllers in residential areas an additional screening with a damping of Z 10 dß is required to

limit

the noise emission. This is usually achieved by installation into enclosed, grounded conrol cabinets or boxes made of metal.

Please note:

l If units,

which

do not comply with the noise immunity EN

50082.

2 required by the CE, are operated next to the Controllers, an

electromagnetic

interference of these units is possible.

5.4 Screenings

Cable screenings increase the noise immunity of the drive

System

and reduce the interfering radiation.

The power and control terminals of the

controllers

are noise

immune without screened cables up to severity class 4 to IEC 801-4. Burst of 4kV on the power terminals and 2kV on the

control terminals are permissible. Screenings are only required when you want to operate the

controller

in environments, where severity class 4 is not

sufficient.

If your drive corresponds to the CE-typical drive

System

and you do not want to carry out the radio-interference measurements necessary for the conformity, screened cables are required.

5.5

Grounding of control electronics

The grounding of the control electronics is to ensure that the potential of the control electronics does not exceed 50V to PE (housing).

Single drives

Bridge the control terminals GND and PE.

Network of several drives

Avoid GND loops. Lead all GND cables to external, insulated

central Points,

centralize again from there and connect to PE in the

central

supply.

Make

Sure

that the grounding of the control electronics does not

darnage any external devices.

6.1

Wake

resistors

In the generator mode, e.g. when decelerating the drive, the

machine

returns energy to the DC bus of the controller. If large inertias are braked and/or short deceleration times are set, the DC bus voltage may exceed its maximum permissible value. In the

case

of overvoltage in the DC bus, the controller sets pulse inhibit and indicates “overvoltage “. The controller cancels the pulse inhibit once the votlage has returned to the permissible range.

To avoid overvoltage

during

braking, a brake chopper is used,

which

switches an external brake resistor when the voltage in the

DC bus exceeds 765 V. The absorbed energy is dissipated as heat so that the voltage in the DC bus does not rise

further.

l The brake chopper is already included in the Standard

controller.

l The suitable brake chopper is available as an Option. It is

connected to the terminals

BR1

and BR2

(see connecting diagram, page 28).

Mains

Chokes

Advantages of using a mains

Choke:

l Less mains disturbance

The wave shape of the mains current

approaches

sinusoidal; at

the same time the

r.m.s.

current is reduced by up to 40%

(reduction

of the mains load, the

cable

load and the fuse load).

l Increased life of the Controller

A mains

Choke reduces

the AC load of the DC bus capacitors

and thus doubles its Service life.

l The transient high-energy overvoltages

which

are sometimes

generated at the mains side by circuit breakers or fuses are stopped by the mains

Choke

and thus the units are usually not

damaged.

l Low-frequent radio interference

tan

be reduced.

Please note:

l When a mains

Choke

is used, the maximum possible output

voltage does not

resch

the value of the mains voltage.

-

typicat voltage drop at the rated

Point:

4 to 5%.

l Mains

are always required when the Controller is

operated with increased or maximum power.

6.3 Motor filter

Advantages of using a motor filter:

. The motor filter

reduces

capacitive currents

caused

by

parasitic

cable capacitances.

l The slope of the motor voltage

(dv/dt)

is limited to 500

V/ps.

Motorfilters are always required for:

l unscreened cables

langer

than 1

OOm.

l screened cables longer than 50m.

o

when using motors

which

do not have suitable insulation for

controller Operation.

(Observe

data of the motor manufacturer.)

Please note:

Install

the motor filter as

close

as possible to the controller

-

Maximum cable length 5 m

Connect

+!JG

and

-!JG

of the motor filter only to the controller

terminals of the same designation. Select the control mode

“V/f-characteristic

control” (CO06 = -0-). The control “magnetizing-current control” is not permissible.

The

chopper

frequency must be 4 kHz. The max. permissible output frequency is 300 Hz. The controller is loaded in addition to the motor

current

with

approx. 12% of the rated filter

current.

The voltage drop

across

the motor filter at rated

current

and

rated frequency

(fd

= 50 Hz) is 2 to 3% of the controller output

voltage.

For motor cable lengths > 100 m (screened) and z- 200 m

(un-

screened) a sine filter should be used. With unscreened motor cables it should be tested whether the

System camplies

with the interference

Lenze offer a series of specially designed connection accessories for the

controllers,

in

Order

to use the fibre

optic

communication

bus. The accessories included adapters with

Optical

transmitter and

receiver,

a distributor and power pack. Due to the

Optical

fibre cables, data transmission with a very high immunity to interferences is possible.

tan

be used to transmit serial Signals

with electrical isolation. Therefore it is possible to

install

widely

distributed drive

Systems

(maximum

cable

length

1200m),

either as

multipoint connection according to

FIS485 or

as

Point-to-Point

connection according to RS422.

Initial switch on

Which

settings are necessary for the drive to operate?

-

, :

After mains connection the controller is ready to operate after

approx. 0.5 seconds. The frequency

controllers

are factory-set such that a four-pole

Standard motor with 400V rated voltage and

50Hz

according to the

combinations

in section 3.1

tan

be operated without

further

settings.

In

case

of motor ratings according to section 3.2 or 3.3, page

17ff,

it is necessary to increase the permanent output power accordingly. Using the

Codes

Cl 19 and Cl 20 the output

current

monitoring must be set to increased power or maximum power (see page 99). The ICI

setpoint (CO20)

must also be adapted to the motor

(see page72).

The motorwill rotate if: .

the controller is enabled: Apply a voltage of 13 to 30V (HIGH

Signal)

across terminal

28.

.

the

direction

of rotation is set :

CW rotation:

Apply a voltage of 13 to 30V (HIGH

Signal)

across terminal 21.

CCW rotation: Apply a voltage of 13 to 30V

(HIGH

Signal

across terminal 22.

.

the

setpoint

is not

Zero:

Apply a voltage

higher

than OV (maximum 1 OV) across terminal

8.

Reference potential for the terminals 21, 22, 28 is terminal 39.

When operating with internal voltage supply (terminal

20),

bridge

terminals 39 and 40. Reference potential for the

setpoint

input terminal 8 is terminal 7.

If you want to operate the controller using the LECOM

program,

additional settings are required.

Basic Parameter setting

Programming of the frequency controller enables the drive to be

adapted to your application. The possible settings are arranged in

Codes,

which are numbered in

ascending Order

and

statt

with the

letter

“C”. Esch code

provides one Parameter which

tan

be

selected according to the application.

-

Parameters

tan

be absolute or relative values of a physical unit

(e.g.

50Hz

or 50% related to

fdmax)

or

numerical Codes

giving

certain

Status

information

(e.g. -O- =

controller inhibited,

-1-

controller enabled).

In

cases

where the Parameters represent values of physical units, it is possible that the increment varies. Example: The maximum field frequency

tan

be set in increments

of 0.1 Hz up to 1

OOHz,

and in increments of 1 Hz from 1

OOHz

upwards. In some

Codes,

Parameters

tan

only be read but not changed.

In the factory setting, only those

Codes

are displayed which are

necessary

for the most common applications. For activation of the

extended

code

set see page 100.

2.1

Changing Parameters

Esch code

has a factory set Parameter which

tan

be changed. There are three different ways of selecting another Parameter, depending on the

Code:

Direct

acceptance

The controller immediately accepts the new Parameter, i.e. while you

Change

it using the UP or DOWN keys. This is possible even

when the drive is running.

Parameters which are immediately accepted are marked with ONLINE in the following programming tables.

Example:

Under CO50,

the controller

Shows

the momentary field frequency in

Hz. You want to set a maximum field frequency (CO1 1) of 60Hz.

Acceptance with SH + PRG

The controller accepts a new Parameter when

SH+PRG

are

pressed. This is possible even when the drive is running. First press SH and then in addition PRG. The display

Shows --ok--

for 0.5 seconds. The controller now works with the new Parameter. The key combination SH and PRG

tan

be compared to the “return”

key on your Computer keyboard.

If yolu

have to set a Parameter in this way, the programming tables

show the

Symbol

SH + PRG.

-

Acceptance with SH + PRG with controller inhibit

The controller accepts the new Parameter when the controller has

been inhibited before pressing SH + PRG.

Inhibit

the controller, e.g. by pressing STP.

First press SH and than in addition PRG. The display

Shows --ok--

for

0.5

seconds. The controller works with the new Parameter

when controller inhibit is cancelled.

If you have to set a Parameter in this way, the programming tables

show the

Symbol

[SH + PRG].

2.1 .lParameter setting by two

Codes

Some Parameters are set by two

Codes.

A preselection

code

is

used to select the Parameter

which

is to be changed. The

Parameter is then changed by another

Code.

For example, to set

the JOG frequency JOG3, first set the preselection

code

CO38 to

-3-

and then set the desired frequency for JOG3 via

code

C039.

2.2 Save Parameters

After the acceptance, new Parameters are saved in the RAM

until

the controller is connected to mains voltage.

If you want to permanently save your

settings,

process as follows:

. Select

code

CO03.

l Select

-l-,

i.e. Parameter set 1.

l First press SH and then in addition PRG. The display

Shows

--ok--.

Now you

tan

disconnect the controller from the mains. Your

settings are saved permanently

under

“Parameter set 1”.

Ta save different Parameter

Sets

see page89.

2.3

Load Parameters

If you only need one Parameter set, you permanently save your

changes under

Parameter set 1. After every mains connection, Parameter set 1 is loaded automatically. To load different Parameter

Sets,

3.2.1

Example of how to select a configuration

The

direction

of rotation of the motor in a

System

is to be

determined by the sign of the analog

setpoint (O...+iOV

for CW

rotating field,

O...lOV

for CCW rotating field).

A closed-loop

Speed

control is to be used, for

which

a DC

tacho

serves as act. value. A

setpoint

2 is not used.

The corresponding configuration

tan

be determined as follows:

The table “Closed-loop

Speed

control” contains two configurations

where the

setpoint

1 is provided analog as bipolar setpoint. These

are the Parameters -1 l- and

-13-.

The desired closed-loop

Speed

control using DC tachogenerator is possible with Parameter

-1

i-.

The

setpoint

2 via terminals 1 and 2 is

active,

but is not

required. Therefore its influence must be set to zero as

protection

from

setpoint

couplings. Please observe the

notes

on page 68.

an HTL-encoder, it is

sufficient to

provide only the

Signals

A and B.

The

inputs

A\ and B\

must

then be bridged using

For applications where the act. value

to the

of the drive (actual

it is advantageous to pilot-

When the output frequency is pilot-controlled using the act. value, the machine is supplied with the

corresponds to the actual

without the influence of the Pl

controller (output

0). The Pl controller is only activated

effective

if

setpoint

and act. value are not identical. When the Pl

controller increases or decreases the output frequency, a torque is

generated in the machine so that the drive accelerates in the

desired

direction.

The advantage of act. value pilot control is that the

setpoint

slew

rate does not have to be limited

(Tir, Tir

= 0) and that the drive

run through a large

Additional functions

For

special

applications, you

tan

use a variety of additional

functions:

Input integral action component = 0

Using this function, the integral action component (I-component) of

the PI controller

tan

be reset to zero. You

tan

activate this additional function via one of the freely assignable digital inputs. Fur

further

information

about

programming of the freely assignable

inputs see page 81.

This function is e.g. useful for applications where a drive

Comes

to

standstill either after zero

setpoint

and remains in standstill without

the controller being inhibited. By resetting the

I-component, a motor drifting is avoided. If the drive is braked mechanically with zero setpoint, a resetting of the 1-component avoids the drive to jerk after releasing the brake.

Output act. value =

The digital function act. value =

DGinjection

brake

If

suitable

input. Please note that the braking time may vary

each

time.

Before you

tan

use the

DGinjection

brake, set the brake voltage

under

C036. The brake voltage also determines the brake current and therefore the brake torque. If the current limitation is activated by the brake current, reduce the brake voltage.

To limit the time of the

DC-injection

brake, you

tan program

a

holding time

under C107.

After the holding time has elapsed, the

Chopper frequency

The

controllers

of the 8600 series offer the feature to adapt the chopper frequency of the controller to the noise and smooth running requirements of the motor. By increasing the chopper frequency you

tan

generally reduce the motor noises

which

are generated by the pulsating output voltage. By reducing the chopper frequency the smooth running in the low frequency range is often improved.

Under code

CO18 you

tan

select a variable or fixed chopper frequency.

Variable chopper frequency

With a chopper frequency, from 4 to 16 kHz variable, the set

chopper frequency is maintained us long as the switching losses in the controller

allow

for this. If an overload is recognized, the chopper frequency is reduced automatically to the extent as it is necessary to continue Operation. If the motor

current

is reduced

again, the chopper frequency is increased.

Fixed chopper frequency

When a fixed chopper frequency is set, the chopper frequency is not reduced in

case

of overload. A fixed chopper frequency is

useful only when the

reduction

of the motor noise is

important

in

every operating state or if motor noise filters are used. By reducing

the maximum

current

internally, the overload

capacity

is restricted.

6.1 .lAutomatic chopper frequency reduction

If

you want to operate the frequency controller with 4 kHz (Cl43

=

-2-

to

-6-)

or a

higher

chopper frequency, but also require an

improved smooth running with low Speeds, you

tan

activate an automatic chopper frequency reduction, restricted to this range. For this, enter the output frequency

under

C143, below which the

chopper frequency is to be reduced automatically to 2 kHz. When selecting the chopper frequencies

“12kHz

fixed”

(CO1 8 =

-7-)

and “16 kHz fixed” (CO18 =

-8-),

you must set Cl43

“Threshold for automatic chopper frequency reduction to 2

kHz”

to

0.0 Hz. Otherwise the controller would reduce its chopper

frequency to 2 kHz below the set threshold. This may darnage or

destroy connected filters.

6.3 Slip

compensation

Under

machine

is considerably

reduced.

You

eliminate this load-dependent

reduction,

also referred to as

by using the

Slip compensation.

In a frequency range from approximately 5 Hz to V/f-rated frequency (CO1

Load-change damping

If

the load frequently

changes

and if energy is repeatedly absorbed by the DC bus of the controller (e.g. cyclic lifting and lowering of a load), the controller is able to damp the increase of the DC bus voltage. The absorbed energy is reduced so that a brake chopper may not be
