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 DIN/VDE 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

Drive 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 50439-1/VDE 0660, part 500, and EN 60146/VDE 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. Installation

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. Electrical connection

When working on live drive 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 sectional 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.

2.4 Application as directed

The controllers of the 8600 series are electrical equipment intended for installation in control cabinets of high power plants.

The controllers are directed as components

• for the control of variable speed drives with three-phase AC

motors.

• for the installation in control cabinets or control boxes.

• for the assembly together with other components to form a

drive system.

• The controllers correspond to the Low-Voltage EMC directive.

• Drive systems with the 8600 controllers which are installed

according to the requirements of the CE-typical drive systems correspond to the EC directive relating to EMC (see chapter

4.2.2).

The CE-typical drive with the 8600 controllers are suitable for

• the operation on public and non-public mains systems.

• the use in industrial areas as well and in residential and

commercial premises.

• Because of the earth-potential reference of the RFI filter, the

described CE-typical drive systems are not suitable for the connection to IT mains (mains without earth-reference potential).

• The controllers are not domestic appliances. They are intended

as drive-system components for commercial use.

• The controllers themselves are not machines for the purpose of

the EC directive relating to machinery.



2.5 CE conformity

What is the purpose of the EC directives?

EC directives are issued by the European Council and are intended for the determination of common technical requirements (harmonization) and certification procedures within the European Community. At the moment, there are 21 EC directives of product ranges. The directives are or will be converted to national standards of the member states. A certification issued by one member state is valid automatically without any further approval in all other member states.

The texts of the directive are restricted to the essential requirements. Technical details are or will be determined by the 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 certification is not necessary according to most directives. Therefore, the customer cannot clearly see which of the 21 EC directives applies to a product and which harmonized standards are considered in the conformity verification.

Drive controllers with the CE mark themselves correspond 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 machine remains the responsibility of the user. For the installation of CE-typical drive systems, Lenze has already proved the CE conformity to the EMC directive.

What is the purpose of the EMC directive?

The EC directive relating to electromagnetic 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. Furthermore, the units must be immune against electromagnetic disturbances to ensure an application as directed.

What is the objective of the Low-Voltage Directive?

The Low-Volgate Directive is effective for all electrical equipment for the use with a rated voltage between 50 V and 1000 V AC and between 57 V and 1500 V DC under normal ambient conditions. The use of electrical equipment in e.g. explosive atmospheres and electrical parts in passenger and goods lifts are excepted. The objective of the Low-voltage Directive is to ensure that only such electrical equipment which does not endanger the safety of man or animals is placed on the market. It should also be designed to conserve material assets.

4 Installation

4.1 Mechanical installation

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

• Install the inverter vertically with the terminal strips at the

bottom.

• Allow a free space of 100 mm at the top and bottom. For the

units 8612 ... 8615 this free space is also required at both sides. Ensure unimpeded ventilation of cooling air.

• If the cooling air contains pollutants (dust, flakes, grease,

aggressive gases), which may impair the inverter functions, suitable preventive measures must be taken, e.g. separate air duct, installation of a fiter, regular cleaning, etc.

• If the inverters are permanently subjected to vibration or

shaking, shock absorbers may be necessary.



4.2 Electrical installation

• The drive controllers are equipped with electrostatically

endangered components. The service and maintenance personnel must be electrostatically discharged before working at the units. They can discharge by touching the PE fastening screw or another earthed metallic surface in the control cabinet.

• All control inputs and outputs of the inverter 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 screwed joint of the set-value potentiometer to PE (assembly kit).

• Not used control inputs and outputs should be covered with

plugs or protective covers which are supplied together with the unit.

• When using current-operated protective units:

− The controllers are equipped with an internal mains rectifier.

As result, a DC fault current may prevent the tripping of the current-operated protective device after a short-circuit to frame. Therefore, additional measures as protective multiple earthing or universal-current sensitive current-operated e.l.c.b. are required.

− When dimensioning the tripping current of current-operated

e.l.c.b. it must be observed that there are capacitive leakage currents between cable screens and RFI filters during operation. These currents may result in false tripping of the current-operated e.l.c.b.

• The regulation about the min. cross-section of PE cables must

be observed. The cross-section of the PE cable must be at least as large as the cross-section of the power connections.

• In the event of condensation, only connect the inverter to the

mains when visible moisture has evaporated.

• Before switching on the inverter for the first time check whether

there is an earth fault at the output side, if this is the case, clear the earth fault. Earth faults which occur during operation are detected, the inverter is then switched off and the message "OC1" is set.

• Frequent mains switching may overload the internal switch-on

current limitation. For repeated mains connection, the inverter must not switched more often than every 3 minutes.

• Replace defective fuses only with the specified type and when

the device is disconnected from the mains. The inverter 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 or thermal contacts can 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 inverter operation:

- Connect motor filters for protection (see page 43). Please contact your motor manufacturer.

Please note:

These frequency inverters 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

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

verified the conformity. In the following this system is called "CEtypical drive system".

If you observe the partially easy measures for the installation of CE-typical drive system, the inverter will not cause any EMC problems and you can be sure to comply with the EMC directive.

• The following configurations can now be selected by the user:

− The user himself can determine the system components and

their integration into the drive system and is then held responsible for the conformity of the drive.

− The user can 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.

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:

• filters,

• screens and

• grounding.

Longer than 0.3 m: Screened power cable with tin-plat ed E -CU brai d (85 % optically covered).

Screened signal cable, paarweise verdrillt, t wisted in pairs, tin-plated E-CU braid (at least 75 % optically covered).

Lenze type DXRA or similar

Filters

Only use suitable mains filters and mains chokes. Mains filters reduce impermissible high-frequency disturbances to a permissible 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 motor supply filter).

Screens

All cables from and to the inverter 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.



Installation

• Connect the inverter, mains filter, 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.

• When using several mounting plates they must be connected

with as large surface as possible (e.g. using copper bands).

• Connect the screen of the motor cable to the screen connection

of the inverter 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.

bare metal

screened cable

mounting surfac

braid

• 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 large surface as possible.

• PE and the screen should be connected in the motor terminal

box. Metal cable glands at the motor terminal 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 inverter is longer

than 0.3 m, the cable must be screened. Connect the screen of the mains cable directly to the inverter module 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 inverter and the brake resistor and it must be connected to the mounting plate with a surface as large as possible.

• The control cables must be screened. Digital control cables

must be screened at both ends. Connect the screens of the control cables to the screen connections of the controllers leaving as little unscreened cable as possible.

• When using the inverters in residential areas an additional

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

≥ 10 dB is required to limit the

ground clamp

Please note:

• If units, which do not comply with the noise immunity EN 50082-

2 required by the CE, are operated next to the inverters, an electromagnetic interference of these units is possible.

4.2.4 Switching on the motor side

Switching on the motor side is permissible for an emergency stop as well as during normal operation.

Please note that when switched with the controller enabled, this may cause the fault message OC1 (short circuit/earth fault). For long motor cables, the fault current on the interfering cable capacitances can become so large that the short circuit monitoring of the device is triggered. In these cases, a motor filter is necessary to reduce the fault currents (see page 43).

5.2.5 Digital inputs and outputs

The functions for the digital inputs and outputs shown below are

factory-set. To switch the signal cables, only use relays with low-

current contacts. Relays with gold-plated contacts have proven for

this.

All digital inputs and outputs are PLC compatible and are - when

operated with an external voltage supply (24 V) - isolated from the

rest of the control stage. To connect the voltage supply, use

terminals 39 and 59. If there is no external voltage supply, the

internal 15 V-supply can be used.

With direct supply into the DC bus, energy feedback is also

possible. If the drive is in the generator mode (braking), the

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 inverters 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 inverter 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 damage any external devices.

6 Accessories

Accessories are not included in the scope of supply.

6.1 Brake 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.

• The brake chopper is already included in the standard controller.

• The suitable brake chopper is available as an option. It is

connected to the terminals BR1 and BR2 (see connecting diagram, page 26).

6.2 Mains chokes

Advantages of using a mains choke:

• 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).

• Increased life of the inverter

A mains choke reduces the AC load of the DC bus capacitors and thus doubles its service life.

• 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.

• Low-frequent radio interference can be reduced.

Heat capacitance

kWs

Please note:

• When a mains choke is used, the maximum possible output

voltage does not reach the value of the mains voltage.

- typical voltage drop at the rated point: 4 to 5%.

• Mains chokes are always required when the inverter is operated

with increased or maximum power.

6.6 RFI filters

Advantage of using a RFI filter:

• Reduction of high-frequent radio interference.

Please note:

• Because of the generation of leakage currents, the RFI filters

must be connected to earth. The RFI filter must always be connected to earth at first even if you only want to test the system. Otherwise, the system is not protected against shock.

• The filters listed in the following can be connected to the 400 V

mains. If you need filters for mains voltages of 460 V or 480 V, please contact the factory.

8 Initial switch-on

Which settings are necessary for the drive to operate?

After mains connection the inverter is ready to operate after approx.

0.5 seconds.

The frequency inverters are factory-set such that a four-pole

standard motor with 400V rated voltage and 50Hz according to the

combinations in section 3.1 can 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 C119 and C120 the output current monitoring must

be set to increased power or maximum power (see page 85). The

set-value (C020) must also be adapted to the motor (see page

70).

The motor will 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 set-value is not zero:

Apply a voltage higher than 0V (maximum 10V) 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 set-value input

terminal 8 is terminal 7.

If you want to operate the inverter using the LECOM program,

additional settings are required.

2 Basic control operations

Programming of the frequency inverter enables the drive to be adapted to your application. The possible settings are arranged in codes, which are numbered in ascending order and start with the letter "C". Each code provides one parameter which can be selected according to the application.

Parameters can be absolute or relative values of a physical unit (e.g. 50Hz or 50% related to f certain status information (e.g. -0- = controller inhibited, -1controller enabled).

In cases where the parameters represent values of physical units, it is possible that the increment varies. Example: The maximum field frequency can be set in increments of 0.1Hz up to 100Hz, and in increments of 1Hz from 100Hz upwards.

In some codes, parameters can 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 99.

) or numerical codes giving

dmax

2.1 Changing parameters

Each code has a factory set parameter which can be changed. There are three different ways of selecting another parameter, depending on the code:

Direct acceptance

The inverter 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 ON- LINE in the following programming tables.

Example: Under C050, the inverter shows the momentary field frequency in Hz. You want to set a maximum field frequency (C011) of 60Hz.



The arrow position marks whether you are in the code or in the parameter level.

max. f r equency

Press, until 60 Hz is displayed

C011 → 60. 0 Hz

max. f r equency

The maximum field frequency of 60Hz is now set and is accepted immediately.

Acceptance with SH + PRG

The inverter 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 inverter now works with the new parameter.

The key combination SH and PRG can be compared to the "return" key on your computer keyboard.

If you have to set a parameter in this way, the programming tables show the symbol SH + PRG.

Acceptance with SH + PRG with controller inhibit

The inverter 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 inverter 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].



2.1.1 Parameter 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 C038 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 inverter is connected to mains voltage.

If you want to permanently save your settings, process as follows:

• Select code C003.

• Select -1-, i.e. parameter set 1.

• First press SH and then in addition PRG. The display shows

--ok--.

Now you can disconnect the inverter from the mains. Your settings are saved permanently under "parameter set 1". To save different parameter sets see page 85.

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, see page 85.

3 Basic settings

3.1 Operating mode

The inverters of the 8600 series offer different interfaces. From these you can select each one for control and programming.

Controller interfaces for control and programming: Terminals The terminals are exclusively used to control the

inverter.

Keypad The five keys and the plain text display can be

used mainly for programming. A control via the keypad is also possible.

LECOM1 LECOM1 means the connection for LECOM-A/B

(connector X6) which can be used for programming via a PC or other master systems. The signals are processed according to the RS232 and RS485 standards. You can connect the inverter to a host using the X6 connector. For further information about LECOM1 see page 109.

LECOM2 For more sophisticated applications, you can

control and program the inverter via a field bus connecting module using LECOM2. Here, the field bus systems InterBus-S or PROFIBUS with the DRIVECOM profile are used. For further information about LECOM2 see page 110.

You can set the desired combination using code C001 "operating mode":

3.1.1 Controller enable

Depending on the selected operating mode (C001) different procedures are necessary to enable the controller.

Terminal control, i.e. C001 = -0-, -2-, -4-

• Apply a voltage between 13 and 30V across terminal 28.

• If you have pressed the STP key, enable the controller with SH

+ STP in addition.

In case of terminal control, C040 serves as a display:

• C040 = -0- means controller is inhibited.

• C040 = -1- means controller is enabled.

Control via keypad, i.e. C001 = -1-

• Apply a voltage between 13 and 30V across terminal 28.

• If you have pressed the STP key, enable the controller with SH

+ STP in addition.

• If you have set C040 to -0- via the keypad, enter C040 = -1- to

enable the controller as well.

3.1.2 Quick stop / Select direction of rotation

Quick stop

The quick stop function (QSP) serves to decelerate the drive to standstill as fast as possible. For this, a deceleration time can be set which is independent of the normally required deceleration times. It can be set via C105.

Code Parameter Meaning Acceptance

C105 5.0s

0.0...990s

Quick stop can always be activated via the terminals 21 and 22 (LOW signal at both terminals), independently of the selected operating mode (C001). When switching on the inverter a HIGH signal (from terminal 20 or external supply) is applied at terminals 21 and 22 the drive is at standstill with the function "QSP".

Deceleration time for quick stop ON-LINE

In case of terminal control, C042 serves as a display:

• C042 = -0- means, quick stop is not active,

• C042 = -1- means, quick stop is active.

If you want to deactivate quick stop:

• Apply a voltage between 13 and 30V across terminals 21 or 22

(CCW rotation).

• If you have set C042 to -1- via the keypad or one of the

LECOM interfaces, deactivate quick stop in addition by setting C042 to -0-.

Select direction of rotation

When operating with terminal control, not only the quick stop is deactivated by applying a HIGH signal across terminal 21 or 22, but also the direction of rotation is selected. Depending on the terminal, CW or CCW rotation results from a positive main setvalue (set-value 1/JOG frequency).

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 set-value (0...+10V for CW rotating field, 0...10V for CCW rotating field). A closed-loop speed control is to be used, for which a DC tacho serves as feedback. A set-value 2 is not used.

The corresponding configuration can be determined as follows: The table "Closed-loop speed control" contains two configurations

where the set-value 1 is provided analog as bipolar set-value. These are the parameters -11- and -13-. The desired closed-loop speed control using DC tachogenerator is possible with parameter

-11-. The set-value 2 via terminals 1 and 2 is active, but is not required. Therefore its influence must be set to zero as protection from set-value couplings. Please observe the notes on page 66.

You have to change from I0 control (factory setting) to V/f characteristic control if you want to supply several drives with different loads or rated power from one inverter. Also for pump and blower drives to be operated with a square characteristic, a V/f characteristic control is required.

• Provide a set-value of 4 to 5 Hz.

• The voltage boost should be set such that

for short-time operation in the low frequency range.

− the motor current (C054) does not exceed 80 % of its rated

4.3 Frequency pilot control

For applications where the feedback signal is directly proportional to the speed of the drive (actual speed) it is advantageous to pilotcontrol the output frequency with the set-value or feedback. The influence of the PI controller can be limited such that only the maximum machine slip to be expected is controlled.

Set-value pilot control

A pilot control of the output frequency with the set-value offers the advantage that the drive cannot accelerate unexpectedly if the feedback signal fails (tacho failure). The ramp generator for the setvalue must be set correspondingly so that the drive is able to follow set-value changes. (T

Actual value pilot control

When the output frequency is pilot-controlled using the feedback, the machine is supplied with the synchronous frequency which corresponds to the actual speed, without the influence of the PI controller (output signal = 0). The PI controller is only activated effective if set-value and feedback are not identical. When the PI 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 feedback pilot control is that the set-value slew rate does not have to be limited (T run through a large speed setting range with the set torque according to the set influence of the PI controller. A disadvantage is that the drive may accelerate unexpectedly in the case of inadequate gain of the actual value.

4.4 Adjustment of the feedback gain

If you use an incremental encoder for speed control and you have entered the encoder constant as described under 4.2. (see page

61) an adjustment of the feedback gain is not necessary. For tacho feedback, a gain adjustment is normally required.

4.4.1 Automatic adjustment

To adjust the feedback gain you can activate an automatic adjustment under C029. Proceed as follows:

• Activate the closed-loop speed control (C005) with pilot control

of the output frequency by the controller reference (C238 = -1-).

• Set the influence of the PI controller to zero under C074.

• Idle running. If this should not be possible, please note that the

slip of the machine is added as gain error during the automatic adjustment. If necessary, set manually.

• If possible, enter 100% set-value. If the set-value is smaller than

10% an auto-adjustment is not possible.

• Enable the controller and wait for the acceleration.

Activate the auto-adjustment via C029 using SH + PRG.

• If the auto-adjustment was successful, "--ok--" appears on the

display. If not, please check your settings. With the acceptance of the auto-adjustment the feedback gain is set under C027.

• Set under C074 the influence of the PI controller such that the

slip occuring during operation can be controlled.

To set the adjustment time and the gain of the PI controller see page 76.



4.4.2 Manual adjustment

If, for technical reasons, the above described automatic adjustment in idle running is not possible or too inaccurate, you can measure the motor speed by hand and calculate the required feedback gain. Proceed as follows:

• Activate the closed-loop speed control (C005) with pilot control

of the output frequency by the controller reference (C238 = -1-).

• If possible, enter 100% set-value. If the set-value is smaller, the

obtainable adjustment result is normally less precise.

• Enable the controller and wait for the acceleration.

Set under C074 the influence of the PI controller such that the slip occuring during operation can be controlled.

• Measure the motor speed.

• Calculate the required feedback gain according to the following

equation:

Required gain = active gain

• Enter the calculated value after selecting the suitable feedback

input (C025) under C027.

4.5 Setting of the controller parameters

With the setting of the controller parameters, you adapt the PI controller to the drive. This adjustment is necessary after the autoadjustment as well as after the manual adjustment. Proceed as follows:

• Increase the gain of the PI controller under code C070 until the

drive starts to oscillate.

• Then reduce this value by 10%.

• If there should be no oscillation with a gain of 10, reduce the

adjustment time under C071, until the drive starts to oscillate.

• Then reduce the gain by 10%.

• If the system already oscillates with the factory setting, increase

the adjustment time, until the drive runs smoothly.

Using this function, the integral action component (I-component) of the PI controller can be reset to zero. You can activate this additional function via one of the freely assignable digital inputs. Fur further information about programming of the freely assignable inputs see page 78.

This function is e.g. useful for applications where a drive comes to standstill either after zero set-value 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 set-value, a resetting of the I-component avoids the drive to jerk after releasing the brake.

5.2.3 DC injection braking

If you want to brake the drive fast, but do not want to use a brake chopper, you can activate the DC injection braking via the suitable input. Please note that the braking time may vary each time.

Before you can use the DC injection braking, 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 braking, you can program a holding time under C107. After the holding time has elapsed, the inverter switches the output voltage to zero. With a holding time of 999s the braking time is unlimited.

A fault is indicated via the permanently assigned digital output terminal 41 and - in factory setting - via the relay output. If you need the output terminal 41 with reverse polarity, you have to use a freely assignable output and set the polarity as required. Before, the relay output must be assigned to another function.

5.4.5 Ready, RDY

The status "ready" is indicated approximately 0.5 seconds after mains connection by the illuminated green LED on the keypad and via the digital output terminal 44.

If you need the permanently assigned output terminal 44 with inverted polarity you must use a freely assignable output and set the polarity as required.

In case of a warning (see page 119) the signal "ready" is cancelled without the inverter being inhibited.

5.4.6 Pulse inhibit, IMP

The status of "pulse inhibit" is indicated by the illuminated yellow LED on the keypad and the permanently assigned digital output terminal 45. Pulse inhibit means that the output of the frequency inverter is inhibited. Possible causes are:

• Controller inhibit

• Fault indication TRIP

• Under-/Overvoltage (see page 119)

If you need the permanently assigned output terminal 45 with inverted polarity you must use a freely assignable output and set the polarity as required.

6 Additional open-loop and closed-loop contr ol

functions

6.1 Chopping frequency

The inverters of the 8600 series offer the feature to adapt the chopping frequency of the inverter to the noise and smooth running requirements of the motor. By increasing the chopping frequency you can generally reduce the motor noises which are generated by the pulsating output voltage. By reducing the chopping frequency the smooth running in the low frequency range is often improved. Under code C018 you can select a variable or fixed chopping frequency.

Variable chopping frequency

With a chopping frequency, from 4 to 16 kHz variable, the set chopping frequency is maintained as long as the switching losses in the inverter allow for this. If an overload is recognized, the chopping frequency is reduced automatically to the extent as it is necessary to continue operation. If the motor current is reduced again, the chopping frequency is increased.

Fixed chopping frequency

When a fixed chopping frequency is set, the chopping frequency is not reduced in case of overload. A fixed chopping 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.

6.1.1 Automatic chopping frequency reduction

If you want to operate the frequency inverter with 4 kHz (C143 =

-2- to -6-) or a higher chopping frequency, but also require an improved smooth running with low speeds, you can activate an automatic chopping frequency reduction, restricted to this range. For this, enter the output frequency under C143, below which the chopping frequency is to be reduced automatically to 2 kHz. When selecting the chopping frequencies "12kHz fixed" (C018 = -7-) and "16 kHz fixed" (C018 = -8-), you must set C143 "Threshold for automatic chopping frequency reduction to 2 kHz" to

0.0 Hz. Otherwise the inverter would reduce its chopping frequency to 2 kHz below the set threshold. This may damage or destroy connected filters.

You can almost eliminate this load-dependent speed reduction, also referred to as slip, by using the slip compensation.

6.6 Process control

By programming a process control you can enter fixed speed profiles which are processed automatically. The process control can consist of a maximum of eight process steps. Each step consists of a set-value (C211), an acceleration or a deceleration time (C212) and the duration of the step (C213). The number of the step to be processed next is entered via C214.

Program the process control as follows:

• Under C210, select the process step which you want to

program.

• Under C211, assign a set-value to this step. This can be the set-

value 1 or one of the 15 JOG frequencies. For further information about the JOG frequencies see page 80.

• Under C212, assign an acceleration or deceleration time to this

step.This can either be one of the ramps which you have set under C012/C013 or one of the additional accleration and deceleration times. For further information about the additional acceleration and deceleration times see page 81.

• Under C213, enter the duration of the process step. Also

consider the time for acceleration. If you enter 9999s, the duration is infinite.

• Under C214, enter the number of the next process step. If you

enter one of the previous steps as the next step, you generate a loop. If you enter parameter -0-, the process control is finished after this step. If the process control is finished, the inverter uses again the set-values and ramp times which were processed prior to the process control.
