3. MECHANICAL INSTALLATION

WARNING

Use the lifting eyes provided if a motor is to be lifted. Do not lift machine sets by suspending the individual machines! Always check the capacity of the hoist before lifting any equipment.

Do not paint over the black case finish of the inverter as this will affect the units thermal performance.

Take suitable precautions to prevent transmission elements from being touched. If the COMBIMASTER is started up without a transmission element attached, the featherkey must be secured in position to prevent it from flying off while the shaft is rotating.

3.1 Mechanical Installation I COMBIMASTER

Tighten down screw-in lifting eyes prior to using the COMBIMASTER.

Stable foundations or mounting conditions and a well balanced transmiss ion element are essential for quiet, vibration-free running. It may be necessary to balance the whole rotor and transmission element.

The rotors are dynamically balanced with a full featherkey inserted as standard. Since 1991 the type of balance has been marked on the drive end of the shaft (shaft end face). F denotes balanced with

full

featherkey; H denotes balanced with

half

featherkey. Bear in mind the type of balance when fitting the transmission element.

Poor running characteristics can arise in cases where the transmission elements have a length ratio of hub length to shaft end length < 0.8 and they run at speeds greater than 1500 rpm. In such cases rebalancing may be necessary, e.g. by reducing the distance by which the featherkey protrudes from the transmission element and the shaft surface.

Please check the following prior to commissioning :

•

The rotor turns freely without rubbing.

•

The motor is assembled and aligned

properly.

•

The transmission elements are adjusted

correctly (e.g. belt tension) and the transmission element is suitable for the given operating conditio ns .

•

All electrical connections, mounting screws

and connecting elements are tightened and fitted correctly.

•

All protective conductors are installed

properly.

•

Any auxiliary equipment that might be

fitted (e.g. mechanical brake) is in working order.

•

Protection guards are installed around all

moving and live parts.

•

The maximum speed is not exceeded.

The maximum speed is the highest operating speed permitted. Remember that motor noise and vibration are worse at this speed and bearing life is reduce d.

•

The above list is not meant to be

exhaustive - additional checks may also be required.

4. ELECTRICAL INSTALLATION

WARNING

4.1 General Wiring Guidelines

The Case size A (CS A) and Case Size B (CS B) COMBIMASTER is designed to operate in an industrial environment where a high level of Electro-Magnetic Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble-free operation. However, if problems are encountered, the following guidelines may prove useful. In particular, grounding of the system 0V at the inverter, as described below, may prove effective.

All equipment must be well earthed using short, thick earthing cable connected to a common star point or busbar. It is particularly important that any control equipment connected to the inverter (such as a PLC) is connected to the same earth or star point as the inverter via a short, thick link. Flat conductors (e.g. metal brackets) are preferred as they have lower impedance at high frequencies.

Use screened leads for connections to the control circuitry. Terminate the ends of the cable neatly, ensuring that long strands of unscreened wire are not left visible.

Separate the control cables from the power connections as much as possible, using separate trunking, etc. If control and power cables cross, arrange the cables so that they cross at 90°.

Ensure that contactors are suppressed, either with R-C suppressers for AC contactors or ‘flywheel’ diodes for DC contactors, fitted to the coils. Varistor suppressers are also effective.

Safety regulations must not be compromised when installing the COMBIMASTER or MICROMASTER Integrated !

4.2 Electrical Installation I MICROMASTER Integrated

The motor wires should be connected in either star or delta configuration on the MIP (check motor rating plate).

WARNING

It is essential that the MIP is correctly earthed to the motor. This is usually achieved using a short earth cable connected between the MIP and a suitable connection point on the motor. Death or severe injury can result if the motor is not correctly earthed. Incorrect earthing can also prevent any MICROMASTER Integrated built-in EMC filter from operating correctly.

4.3 Electrical Installation I COMBIMASTER and MICROMASTER Integrated

Procedure

Remove the four cross-head screws on the inverter's cover to access the electrical terminals.

For details of cable sizes, refer to the Electrical Data (section

8.4) of this document.

A ‘drip loop’ is recommended when connecting the mains and control cables (

see Fig. 6

CAUTION

The printed circuit boards contain CMOS components that are particularly sensitive to static electricity. For this reason avoid touching the boards or components with your bare hands or metal objects.

4.4 Mains Cable Connections

Ensure that the power source supplies the correct voltage and is designed for the rated current. Use the appropriate circuitbreakers with the specified current rating between the power supply and inverter.

Use Class 1 60/75

C copper wire only. Use a 4-core screened cable. If crimp terminals are used they must be insulated. If crimps are not used, the strip length must not exceed 5mm.

Feed the power cable into the inverter via the gland hole nearest to the motor shaft. Connect the power leads to terminals L1, L2, L3 (L1, L2 for single phase units) and the separate earth.

Use a 4 - 5 mm cross-tip screwdriver to tighten the terminal screws

5. OPERATING INFORMATION

WARNING

The equipment must not be switched on until after its cover has been fitted and the cover screws have been tightened to the correct torque.

After the power has been turned off, you must always wait five minutes so that the dc link capacitors can discharge. Do not remove the cover until this time has elapsed.

All settings must only be entered by qualified personnel, paying particular attention to the safety precautions and warnings.

5.1 General

For basic operation of COMBIMASTER & MICROMASTER Integrated, no additional equipment is required. However, for more complex operation, Opm2 – Clear Text Display is required (Opm2 is available as an option, but must be ordered separately).

The inverter does not have a mains power switch and is therefore live when the mains supply is connected.

When delivered, the inverte r has a frequen cy setpoint range of between 0 Hz and 50 Hz. Regardless of its initial position, internal potentiometer R314 must be turned fully counter-clockwise before it can be used to start the COMBIMASTER.

R314 can be accessed by removing the right-hand gland hole cover

(see Fig. 2 &

Connecting a serial link or the OPm2 to the serial interface is made using the circular connector SK200 (see fig. 2 & 3)

Parameter settings can only be changed by using either the serial interface (SK200) or an optional Clear Text Display (OPm2). Refer to the parameter list section in this document for a full description of each available parameter.

Analogue input type is selected by jumpers JP300 and JP301. JP300 closed selects current input, JP301 closed (default) selects voltage input. These jumpers can only be accessed when the cover is removed

(see

Fig. 2 & 3)

If the motor is run unloaded (e.g. for test purposes) and vibration or trip conditions occur, change P077 from 0 to 3 (requires OPm2).

5.2 Basic Operation

There are two basic modes of operation for the inverter.

Using the internal potentiometer only:

For forward rotation, ensure that a link is fitted between DIN1 (pin 5) and P10+ (pin 1) on PL800/PL700

(see Fig. 4)

. For reverse rotation, connect the link to DIN2 (pin 6) instead of DIN1.

Apply mains power. The green and yellow LEDs will illuminate to show that power is applied. Turn potentiometer R314 fully counter-

clockwise. Turn the potentiometer clockwise until the yellow LED extinguishes. This indicates that power is now applied to the motor. Continue turning clockwise to increase the speed of the motor.

Turn the potentiometer counterclockwise to reduce the speed of the motor. Turning the potentiometer fully counterclockwise causes the motor to slow to a complete stop. Check that both LEDs are illuminated (STANDBY mode).

Page 19

COMBIMASTER & MICROMASTER Integrated

REFERENCE MANUAL

Siemens plc. 1999

| G85139-H1731-U300-D2

Using a combination of the internal potentiometer and a run/stop switch:

Connect a run/stop switch between DIN1 (pin 5) and P10+ (pin 1) on PL700 (see Fig. 4) if forward rotation is required. If reverse rotation is required instead, conn ec t the switch to DIN2 (pin 6) instead of DIN1 (pin 5).

IMPORTANT:

Remove the link, if fitted, between pins 5 and 1 before the run/stop switch is fitted.

Apply mains power. The green and yellow LEDs will illuminate to show that power is applied.

Set the external run/stop switch to ON.

Turn potentiometer R314 clockwise to set the required motor speed.

Stop the motor by setting the external on/off switch to OFF. When the switch is set to ON again, it will run at the speed previously set using the potentiometer.

5.3 Operation – External Analogue Control

Connect a 4.7 kΩ potentiometer to the control terminals as shown in Fig.4 or apply a 0 - 10 V signal between pin 2 (0V) and pin 3 (AIN+). In both cases, position jumper JP304 to connect 0V to AIN-.

Ensure that a link is fitted between pin 5 (DIN1) and pin 1 (P10+).

Check that voltage input is selected by ensuring that the jumper is fitted to JP301.

Refit the cover, tighten the cover screws to the correct torque and then apply mains power to the inverter.

Turn the external potentiometer (or adjust the analogue control voltage) until the desired frequency is achieved. The unit will not switch on until a minimum of 2 V has been applied.

The frequency set by the external voltage is added to the frequency set by the internal potentiometer. Refer to Parameter P331 , Section 6.

As with Basic Operation, a run/stop switch can be used to start and stop the motor, or the direction of rotation can be changed by connecting the link to DIN2 instead of DIN1.

5.4 Operation – Digital Control

This method of operation requires either a Clear Text Display (OPm2) or a serial link connection. The use of the Clear Text Display module is described in the Options section of this document. For a basic startup configuration using digital control, proceed as follows:

Remove the link that connects control terminal 5 to terminal 1 (if one has been fitted).

Connect control terminal 5 to terminal 1 via a simple on/off switch. This sets up the inverter for clockwise rotation (default). If counter-clockwise operation is required, connect a switch between control terminals 6 and 1.

Connect the OPm2 or serial link to SK200. Refit the cover, tighten the cover screws to the correct torque and then apply mains power to the inverter.

5.5 Stopping the Motor

Via the external on/off switch:

Setting the switch to OFF overrides the setting on the potentiometer and causes the motor to come to a controlled stop.

Via the potentiometer:

Turning the potentiometer counterclockwise until the input voltage drops below 2 V causes the motor to slow to a stop. If an external potentiometer is applied, the input voltage must also be below 2V to stop.

5.6 If the Motor Does Not Start Up

Check the LEDs on the side of the inverter:

LED State COMBIMASTER / MICROMASTER Integrated

If a fault occurs:

Switch off, disconnect and then reconnect the power, and then switch on again. Switch off if the fault condition persists. Trips can be reset by using DIN3.

If a warning occurs:

Switch off, disconnect and reconnect the power and then switch on again.

If the fault/warning persists, further investigation requires an OPm2 or a serial link connection.

5.7 Local and Remote Control

The inverter can be controlled either locally (default), or remotely via a USS data line connected to the RS485 connector (SK200).

When local control is used (P910 = 0), the motor can only be controlled via the internal potentiometer or the control terminals. Control commands, setpoints or parameter changes received via the RS485 interface have no effect.

For remote control, the serial interface is designed as a 2-wire connection for bidirectional data transmission. Refer to parameter P910 in System Parameters for the available remote control options.

When operating via remote control the inverter will not accept control commands from the terminals.

Exception: OFF2 or OFF3 can be activated via parameter P051 to P053 (refer to parameters P051 to P053 in System Parameters).

31 COMBIMASTERS can be connected to an external control unit at the same time and can be addressed individually.

5.8 Closed Loop Control

Closed loop control is only possible when an OPm2 or a serial link is connected to the COMBIMASTER.

5.8.1 General Description

The COMBIMASTER provides a Proportional/Integral (PI) control function for closed loop control

(see Figure 8)

. PI control is ideal for temperature or pressure control, or other applications where the controlled variable changes slowly or where transient errors are not critical. This control lo op is

not

suitable for use in systems where f ast response t imes are required.

Note:

The closed loop function is not designed for speed c ontrol, but can be used for this provided that fast response times are not required.

When closed loop PI control is enabled ( P201 = 002), all setpoints are calibrated between zero and 100%, i.e. a setpoint of 50. 0 = 50%. This allows general purpose control of any process variable that is actuated by motor speed and for which a suitable transducer is available.

6. SYSTEM PARAMETERS

6.1 Systems Parameters Table

The parameters listed here can only be accessed via the OPm2 or a serial link to the COMBIMASTER. (see Section 7.1 for details)

If the COMBIMASTER is to be operated only using analogue control within the 0 - 50 Hz frequency range then access to these parameters is not required.

The control buttons on the OPm2 (RUN, REVERSE and JOG) are disabled by default and cannot be used until P007 has been set to ‘1’.

Access to parameters is determined by the value set in P009. Check that the key parameters necessary for your application have been programmed.

P009 options are:

•

0 = Only the parameters from P001 to

P009 can be read and set.

•

1 = Parameters P001 to P009 can be set

and all other parameters can only be read.

•

2 = All parameters can be set, but P009

resets to 0 the next time power is removed from the inverter.

•

3 = All programmed parameters can

always be set.

In the following parameter table: Software Versions : Where indicated, some parameter descriptions are dependent on

the software version installed, which can be checked using Parameter P922.

Only effective if the relay output is set to control an external brake (P061 = 4) or the electro-mechanical brake option is used (P062 = 4).

P064

External brake stopping time (seconds)

0 - 20.0

[1.0]

As P063, only effective if the relay output is set to control an external brake (P061 = 4) or the electro-mechanical brake option is used (P062 = 4). This defines the period for which the inverter continues to run at the minimum frequency after ramping down and while the external brake is applied.

ON OFF

t P063 A

t P064 A

A = Brake applied B = Brake removed

Settings for P063 and P064 should be slightly longer than the actual time taken for the external brake to apply and release respectively.

Setting P063 or P064 to too high a value, especially with P012 set to a high value, can cause an overcurrent warning or trip as the inverter attempts to move a locked motor shaft.

P065

Current threshold for relay (A)

0 - 99.9

[1.0]

This parameter is used when P061 = 9. The relay switches on when the motor current is greater than the value of P065 and switches off when the current falls to 90% of the value of P065 (hysteresis).

P066

Do not use!

P071

••••

Slip compensation (%) 0 - 200

[0]

The inverter can estimate the amount of slip in an asynchronous motor at varying loads and increase its output frequency to compensate. This parameter `fine tunes' the compensation for different motors in the range 0 - 200% of the inverter's nominal estimate.

P072

••••

Slip limit (%)

0 - 500

[500]

This limits the slip of the motor to prevent `pull-out' (stalling), which can occur if slip is allowed to increase indefinitely. When the slip limit is reached, the inverter reduces the frequency until the level of slip is acceptable.

P073

••••

DC injection braking (%)

0 - 150

[0]

This stops the motor by applying a DC current. This causes heat to be generated in the motor rather than the inverter and holds the shaft stationary until the end of the braking period. Braking is effective for the period of time set by P003.

CAUTION: If a start signal is given during this time, the motor will restart at the end of the braking period.

The DC brake can be activated using DIN1 - DIN3

(braking

is active for as long as the DIN is high - see P051 - P053)

Frequent use of long periods of dc injection braking can cause the motor to overheat.

If DC injection braking is enabled via a digital input then DC current is applied for as long as the digital input is high. This causes heat in the motor.

P074

••••

I2t motor de-rating

0 - 1

[0]

0 = Disabled 1 = Enabled. Causes an F074 trip if the motor I

t calculation reaches its limit. The time taken to trip is dependent on the difference between the overload current and the nominal motor current rating stored in P083 - typically a 150% overload will result in a switch-off in 1-2 minutes.

For safety-critical applications, it is recommended that a motor PTC is used to protect the motor from overheating.

P076

••••

Pulse frequency 0 – 3

[0 or 2]

[2]

Sets the pulse frequency (from 8 to 16kHz). If silent operation is not absolutely necessary, the losses in the inverter can be reduced by selecting lower pulse frequencies.

0 & 1

= 16 kHz (- Default for 230 V inverters)

2 & 3

= 8 kHz (- Default for 400V inverters).

This is suitable for centrifugal pumps and fans.

= Linear voltage/frequency with energy saving. Output voltage is reduced at low load (not recommended for dynamic loads).

P078

••••

Continuous boost (%)

0 - 250

[50]

Operates continuously over the whole frequency range. For many applications it is necessary to increase low

frequency torque. This parameter sets the start-up voltage at 0 Hz to adjust the available torque for low frequency operation. 100% setting will produce rated motor current at low frequencies.

If P078 is set too high, overheating of the motor and/or an overcurrent trip (F002) can occur.

P079

••••

Starting boost (%) 0 - 250

[0]

For drives which require a high initial starting torque, it is possible to set an additional current (added to the setting in P078) during ramping. This is only effective during initial start up and until the frequency setpoint is reached.

This increase is in addition to P078, but the total is limited to 250%.

7.2 PROFIBUS CB155

This option allows the COMBIMASTER to be controlled via a PROFIBUS-DP serial bus (SINEC L2-DP).

PROFIBUS-DP is a cost-effective high spee d serial communication system optimised for the actuator/sensor area where very short system reaction times are critical. It operates as a decentralised I/O system whereby the traditional wiring to the sensors and actuators is replaced by an RS485 serial bus system linking the stations together.

The suitability of the system for such applications has been recently enhanced by the extension of the bus speed up to 12MBd. The protocol is defined as DIN19245 and also as EN50170 guaranteeing open, multi-vendor communications between PROFI BU S-D P stations.

Up to 125 stations can be networked together using this single bus system and a very flexible data structure allows the system to be optimised to exactly match the requirements of each device.

PROFIBUS-DP lies at the heart of the new generation of SIMATIC S7 automation systems offered by Siemens. Using this single bus system, all engineering, visualisation and PLC control operations can be integrated. To configure a SIMATIC based automation system, all that is required is the associated STEP7 configuration tool running on a PC. Bus configuration is performed by using a drag and drop technique in a graphically displayed PROFIBUS-DP network.

Below are listed some of the advantages of automating a system with PROFIBUS-DP:

•

Only one single network for operator

panels, drives, sensors, actuators, PLCs.

•

Cost savings in installation time and

cabling.

•

Ease of commissioning with the

SIMATIC S7 PLC system and STEP7 software.

Flexibility to expand or modify the automation system at a later date. Simple integration into higher level process visualisation systems such as PCS7. Remote diagnostics reduce the down-time in the event of a problem.

Features of CB 155 PROFIBUS Option:

•

Permits fast cyclic communications via

a PROFIBUS connection.

•

Supports all PROFIBUS baud rates up

to 12MBd.

•

Control of up to 125 inverters using

PROFIBUS-DP protocol (with repeaters).

•

19245 and EN50170 guaranteeing open communications on a serial bus system. It can be used with other PROFIBUSDP/SINEC L2-DP peripheral devices on the serial bus. Data format conforms to the VDI/VDE directive 3689 “PROFIBUS Profile for Variable Speed Drives”.

•

Can be easily configured using

Siemens COM ET 200, COM ET Windows or S7 Manager software.

•

Simple integration into a SIMATIC S5

or S7 PLC system using specially designed functional blocks (S5) and software modules (S7).

•

Simply fits to the side of the

COMBIMASTER inverter using two screws.

•

No separate power supply necessary.

•

Digital and analogue inputs can be read

and the digital output controlled via the serial bus.

•

Approx. 5 ms response time to process

data.

•

Output frequency (and therefore motor

speed) can be controlled locally on the drive or over the serial bus.

•

Multi-mode operation possible, whereby

control data can be input via the terminal block (digital inputs) and set point over the serial bus. Alternatively, the set point can be from a local source (analogue input) with the drive control over the serial bus.

•

All drive parameters are accessible

over the serial link.

The PROFIBUS module fits to the side of the COMBIMASTER using two screws.

1. A clear text operator panel (OPM2) is required to set the COMBIMASTER parameters prior to connecting the PROFIBUS module.

2. The PROFIBUS Module may only be connected or disconnected from the drive when the drive is powered off.

3. The PROFIBUS module must only be connected to the drive with the cable supplied for the purpose.

4. The PROFIBUS module cannot be used simultaneously with the Clear Text Display module.

The data structure for communication over PROFIBUS-DP can be either PPO type 1 or PPO type 3 as specified in VDI/VDE 3689. This means in practice that process data (control words, set-point in the transmitted telegram and status words, actual values in the received telegram) is always sent.

Parameter data exchange may, however, be blocked if bus or PLC memory space is at a premium. The data structure and thus the PPO type is normally specified by the bus master. If no PPO type is specified (e.g. if a combined DP/FMS bus master is used), then the default PPO type is type 1 (parameter data enabled). Parameter write access over the serial link can be enabled or blocked as required.

For more detailed Information , refer to Profibus Manual

Parameter read access is permanently enabled, allowing continuous read out of drive data, diagnostics, fault messages etc. A visualisation system can thus be realised with minimal effort.

The PROFIBUS cable is connected to the 5way miniature circular socket on the side of the PROFIBUS Module, via a special ‘T’ connector which fits to the edge of the module. This T connector allows the PROFIBUS module to be disconnected from the bus in the event of a fault, without breaking the PROFIBUS link. The pin designation of the circular connectors is given below.

Recommendation: RS 485 repeater (Order No.: 6ES7 972-0AA00-0XA0).

For reliable operation of the serial bus system, the cable must be terminated at both ends using terminating resistors. For operation at 12MBd, cables must be terminated in connectors with a built-in damping net work (built into T Connector). Additionally, for 12MBd operation, no stub length from the main bus cable is allowed. Suitable SINEC-L2 DP connectors and cable for reliable operation up to 12MBd are detailed above. A floppy disk is supplied with the PROFIBUS module containing the handbook and two data files for configuring the relevant PLC system.

Quick Guide to Setting Up PROFIBUS Communications

•

The bus cable between the master device

and the drive must be connected correctly. This includes the necessary termination resistors and (for 12MBd) the terminating network.

•

The bus cable must be screened and the

screen must be connected to the housing of the cable connector.

•

The PROFIBUS master must be configured

correctly so that communications can be realized with a DP slave using PPO type 1 or PPO type 3 (only PPO type 1, if the PPO type cannot be configured via remote operator control).

•

When using COM ET software with a

SIMATIC S5, the correct type description file must be used, so that an IM 308B/C can be configured as bus master. When using the Simatic Manager for an S7, the Object Manager must be loaded.

•

The bus must be operational (for a

SIMATIC module, the operator control panel switch must be set to RUN).

•

The bus baud rate must not exceed 12

MBd.

•

The PROFIBUS Module must be correctly

fitted to the inverter and the inverter must be powered up.

•

The slave address for the drive (parameter

P918) must be set so that it corresponds to the slave address configured at the PROFIBUS master, and must be uniquely defined on the bus.

7.4 Brake Options

Pulse Resistor Braking Unit

(Only available for CS B Inverters)

The pulse resistor braking unit gives the COMBIMASTER increased immunity to over voltage trips, and can also be used to provide up to 7kW (peak) of braking power for stopping the system more quickly than would otherwise be possible.

The braking unit fits in place of the standard cover for the inverter unit. It houses the braking control electronics, and a 7kW (peak) braking resistor with heat sink. Full IP65 environmental protection is maintained.

Technical Overview

The electronics operates completely independently of the inverter electronics, monitoring the DC link voltage. During braking, the motor will regenerate, causing the DC link voltage to rise. When a set threshold is reached, the unit switches the resistor onto the DC link, causing the regenerated energy to be dissipated as heat in the resistor, and preventing an over voltage trip.

While the resistor is switched on, its temperature will rise. When a threshold temperature (Tmax) is reached, the unit will limit the power in the resistor to approximately 5% of the peak power. (350W). If the temperature continues to rise, the resistor will be disabled completely, until the temperature has reduced. The following diagrams show the relationship between braking power, and resistor temperature with time.

T2T1

Tmax

Figures given below are for a 7kW (peak) braking unit. T1 and T2 are variable, depending on ambient temperatur e. However typical figures are given.

P1 - 7kW P2 - 350W T1 - 5 Seconds typical T2 - 100 Seconds typical

Protection

In the event of a braking unit fault, it is possible for the resistor to become permanently connected, and to overheat. The resistor temperature is monitored by an internal circuit, and if it becomes too hot , this is indicated by a fault relay. This relay should be used to control an external contactor, to remove power from the COMBIMASTER. See the braking unit installation instructions for more information.

Page 52

COMBIMASTER & MICROMASTER Integrated REFERENCE MANUAL

Siemens plc. 1999

| G85139-H1731-U300-D2

Electromechanical Brake Control

The electromechanical brake control, allows the COMBIMASTER to directly control an electromechanical brake. The brake control fits in place of the standard cover for the inverter unit. Full IP65 environmental protection is maintained. The unit provides an output to drive the coil of a DC electromechanical brake. It can be configured for both fast, and slow operation of the coil. The unit is set up using the parameters P062, P063 and P064, which allows full control of the brake release time, and brake stopping time.

Brake coil voltage output will be 180VDC for 400V mains input, and 205VDC for 230V mains input.

Note that the coil voltage for 400V units of 180VDC is not suitable for the standard Siemens electromechanical brake option G26. (refer to Siemens Catalogue M11)

For other mains voltages, the coil voltage will be:

0.9*Vmains for Vmains = 208V to 240V

0.45*Vmains for Vmains = 380V to 500V.

8.6 Output Current Ratings - MICROMASTER Integrated

The MICROMASTER Integrated is designed to be fitted to a motor, and in most cases, to use air from the motor fan for cooling of the inverter. For this reason it is not possible to specify continuous current ratings which will be achieved under all circumstances. This section provides information about the designed current ratings, and explains the factors which effect the continuous ratings achievable when the inverter is installed on a motor.

Introduction

There are two factors in the design of an inverter which define what curr ent can be delivered the motor : The first factor is the selection of electronic components. For example, the current rating of the transistors in the output stage of the inverter. This factor normally limits the peak (short time) current that the inverter can provide.

The second factor is the method of cooling of the inverter. Whenever current flows through a conductor, or an electronic component, heat is generated. The cooling method chosen for the inverter must be able to remove enough heat so that when the inverter is run at its maximum current rating

continuously

then

none of the components in the inverter exceed their rated operating temperatures. With a standard inverter, the cooling method is part of the design of the inverter, therefore it is possible to specify the continuous current ratings of the inverter when it is correctl y installed.

The cooling efficiency for MICROMASTER Integrated is dependant upon the motor to which it is fitted, and therefore the continuous current rating must be determined by thermal tests, when the inverter is fitted to the target motor.

Designed Current Ratings.

The following table gives the

designed

current ratings for the MICROMASTER Integrated. All the inverters are capable of short-term overload up to 150% of the values shown.

Continuous Current Ratings.

As explained above, the continuous rating depends on the amount of cooling available for the inverter from the motor fan. This can be affected by one or more of the following:

Size of Motor Fan Cover Cutout

There must be a hole cut in the motor fan cover to allow air from the motor fan to be directed onto the inverter heatsink. The size and shape of this hole affects the airflow to the inverter.

Position of the Inverter

Ideally, the inverter should be positioned so that the hole in the motor fan cover is centered directly beneath the inverter heatsink. In addition, the vertical distance from the fan cover to the inverter heatsink should be as small as possible.

Motor Speed

When the motor fan is driven by the motor shaft, then a slower motor will have less air flow to the inverter.

Mains Voltage

When the 380 to 500V inverters are operated on a high mains voltage, there is normally more heat generated in the inverter. This will result in a lower continuous current rating. This is not normally a problem, because a motor operated at the higher voltage will require less current to deliver the same shaft power.

9. SUPPLEMENTARY INFORMATION

9.1 Application Example

Set-up Procedure for a Simple Application

Application requirements: Normal operating frequency set within range 15 - 50 Hz via an

external potentiometer. Counter-clockwise rotation required. COMBIMASTER used: Any model. Procedure:

Remove the link (if fitted) between control terminals 5 and 8.

Connect a simple on/off switch to control terminals 6 and 8 for

reverse rotation.

Connect a 4.7 kΩ potentiometer to the control terminals

(see

Figure 4)

Set jumper JP301 (‘V’ - voltage) -

see Fig.3(CS A), Fig.2 (CS B)

Set the internal and external potentiometers fully counterclockwise and then apply mains power and switch on.

Turn the internal potentiometer clockwise until the motor rotates at

a speed that approximates to 15 Hz.

The external potentiometer now has a range of between 15 Hz at

its lowest setting and 50 Hz at its highest setting.

9.2 Motor Interface Plates

Since approximately 01/99 all 1LA5 motors used with COMBIMASTER & MICROMASTER Integrated have been replaced with the 1LA7 equivalents. This has resulted in changes to the motor interface plates (MIP) used with Siemens Motors.

For each inverter case size there are now 3 basic types of motor interface plate: 1LA5

1LA7 ‘Universal’

The 1LA5 and 1LA7 interface plates are for use with the Siemens motors. The ‘Universal’ plate has been designed to simplify adapting the COMBIMASTER for other motors. In

most cases, the ‘Universal’ motor interface plate can be used with a simple flat metal ‘Base Plate’ and no tooling is required.

The following pages describe the MIPs.

9.3 Electro-Magnetic Compatibility (EMC)

All manufacturers / assemblers of electrical apparatus which performs a complete intrinsic function which is placed on the market as a single unit intended for the end user must comply with the EMC directive EEC/89/336 after January 1996. There are three routes by which the manufacturer/assembler can demonstrate compliance:

1. Self-Certification

This is a manufacturer's declaration that the European standards applicable to the electrical environment for which the apparatus is intended have been met. Only

standards which have been officially published in the Official Journal of the European Community can be cited in the manufacturer's declaration.

Technical Construction File

A technical construction file can be prepared for the apparatus describing its EMC characteristics. This file must be approved by a ‘Competent Body’ appointed by the appropriate European government organisation. This approach allows the use of standards which are still in preparation.

EC Type-Examination Certificate

This approach is only applicable to radio communication transmitting apparatus.

The MICROMASTER Integrated units do not have an intrinsic function until connected with other components (e.g. a motor). Therefore, the basic units are not allowed to be CE marked for compliance with the EMC directive. However, full details are provided below of the EMC performance characteristics of the products when they are installed in accordance with the wiring recommendations in section 4.1 of this document.

Class 2: Filtered Industrial (Class A)

This level of performance will allow the manufacturer/assembler to self-certify their apparatus for compliance with the EMC directive for the industrial environment as regards the EMC performance characteristics of the power drive system. Performance limits are as specified in the Generic Industrial Emissions and Immunity standards EN 50081-2 and EN 50082-2.

The COMBIMASTER is intended

exclusively for professional applications

. Therefore, it does not fall within the scope of the harmonics emissions specification EN 61000-3-2.

9.4 Environmental Aspects

Transport and Storage

Protect the COMBIMASTER/MMI against physical shocks and vibration during transport and storage. The unit must also be protected against water (rainfall) and excessive temperatures

(see section 6).

The packaging is re-usable. Retain the packaging or return it to the manufacturer for future use.

Dismantling and Disposal

The component parts can be recycled, disposed of in accordance with local requirements or returned to the manufacturer.
