• Use only Residual Current-operated protective Device (RCD) type B if an RCD is required

• Wait at least five minutes after the power has been turned off, before opening the equipment. The dc-link capacitor remains charged to dangerous voltages even when the power is removed. When working on equipment with covers removed, note that live parts are exposed and do not touch these parts

• Do not connect machines with a three-phase power supply, fitted with EMC filters, to a supply via an ELCB (Earth Leakage Circuit Breaker - see DIN VDE 0160, section 6.5)

• Note that certain parameter settings may cause the inverter to restart automatically once power is restored following an input supply failure.

• Do not use this equipment as an “emergency stop” mechanism (see EN 60204, 9.2.5.4)

• This equipment is suitable for use in a circuit capable of delivering not more than 100,000 symmetrical amperes (rms), for a maximum voltage of 230/460V* when protected by a time delay fuse* * As detailed in sections 9.1 and 10.5 respectively.

• Do not operate the motor with a higher nominal power than the inverter, or a nominal power less than half the inverter. Only operate the inverter when the nominal current in P083 exactly matches the motor rating plate nominal current

• Enter the motor data parameters (P080-P085) and do an auto-calibration (P088) before the motor is started. Unstable/unpredictable motor operation (e.g. Reverse rotation) may result if this is not done. If this instability occurs, the mains supply to the inverter must be disconnected.

• When using the analogue input, the DIP switches must be correctly set and the analogue input type selected (P023) before enabling the analogue input with P006. If this is not done the motor may start inadvertently.

ECO OPERATING INSTRUCTION MANUAL

The Eco Operating Instructions booklet (which should be read in conjunction with this manual) provides basic information on equipment installation and programming, to control the functions of fans and pump motors. It is aimed at HVAC Installation Technicians and Electricians working and commissioning on-site, and is intended to provide a quick, straightforward guide to installing and simple operating of the Eco units.

ECO REFERENCE MANUAL

This Manual - The Eco Reference Manual is intended for use by a wide range of HVAC professionals. For example, the Eco Reference Manual is to be used by Building Automation Engineers to plan their equipment and cabling schedules and estimate their material requirements. HVAC Consultants may also use it in order to compile the relevant portions of their tender specification.

The ability to easily control the speed of pump or fan motors provides superior regulation and control of the process, enabling optimisation of room temperatures and personal comfort levels.

The Eco range combines ease of installation and commissioning with low maintenance and operating costs. In addition, the specific HVAC product functionality (compared with similar products aimed at “Hi-Tech” multiple applications) means that product costs can be minimised, and the user does not pay for features which are not required.

Day-to-day operating costs can be drastically reduced - up to 60% in some applications. Energy consumption and associated emissions are also reduced to the lowest possible levels.

The Eco Reference Manual should also be useful to electrical panel builders, building automation control engineers, quantity surveyors / estimators, electrical project managers, and maintenance contractors.

3. PRINCIPLES OF INVERTER OPERATION

INTRODUCTION

This section of the manual is intended to help first-time users of variable speed drives to understand basic principles of operation, and gain some insight into successful installation and application of the MICROMASTER Eco range of Variable Speed Drives.

VARIABLE SPEED DRIVES

A Variable Speed Drive (VSD) system consists of a Motor and some form of speed controller.

History

Early electric VSDs consisted of AC and DC motor combinations which were used as rotating AC to DC converters. The DC supply was used to drive the DC motor at variable speed by controlling the field current in the DC generator to vary the DC voltage to the DC motor.

The first electronic controllers used Thyristor (SCR) Rectifiers which controlled the voltage, and therefore the speed of DC motors. These DC

VSDs are still widely used and offer very sophisticated control capability. However, the DC motor is large, expensive and requires periodic brush maintenance.

Present day

The AC induction motor is simple, low cost, reliable and widely used throughout the world. In order to control the speed of an AC induction motor a more complex controller, which varies the frequency as well as the voltage, usually called an inverter is required.

Induction motor

In order to understand how an inverter works, it is first necessary to understand how an induction motor works.

An asynchronous induction motor works like a transformer. When the stator (the fixed, outer winding) is connected to a three phase power source, a magnetic field which rotates at the frequency of the supply is set up.

Simplified Induction Motor - Cross Section

Stator windings

Air gap

Rotor

Shaft

3-1

Page 9

ECO REFERENCE MANUAL

This field crosses the air gap between the stator and rotor and causes currents to flow in the rotor windings. This produces a force (torque) on the rotor as the current interacts with the changing magnetic field, and the rotor turns.

If the windings are arranged in several pairs (or poles), the frequency of the rotating field will be less than the applied frequency (e.g. two pole = 50/60Hz = 3000/3600 rpm, but four pole = 50/60Hz = 1500/1800 rpm).

Torque

However, if the rotor runs at the same speed as the rotating field, there will be no changing magnetic field, and therefore no torque.

Since rotor currents must be induced in order to create output torque, the rotor always runs a little slower than the rotating field. This difference in speed is known as slip and is generally about 3%.

Pull out (maximum) torque

Normal operating point

Torque Speed Characteristic of An Induction Motor

The speed of the motor depends on the applied frequency, as well as the winding arrangement, and to some extent on the load.

Therefore in order to control the motor speed it is necessary to control the frequency of the supply.

If the frequency is reduced, the voltage must be reduced, or the stator current and magnetic flux will be too high and the motor’s magnetic field will saturate. Hence the voltage must be controlled as well.

Variable frequency operation

Speed

Slip

If the frequency is increased above normal, more voltage would normally be needed to maintain maximum flux; this is not usually possible, so less torque is available at high speed, (i.e. speeds above the supply frequency).

Torque Reduction above Base Speed

Therefore in order to control the speed of a standard AC motor, the applied frequency and voltage must be controlled.

The use of a standard induction motor together with a variable frequency speed controller allows a cost effective speed control system to be built.

VARIABLE FREQUENCY INVERTER.

An electronic converter which converts Direct Current (DC) to Alternating Current (AC) is known as an inverter. Electronic speed controllers for AC motors usually convert the AC supply to DC using a rectifier, and then convert it back to a variable frequency, variable voltage AC supply using an inverter bridge. The connection between the rectifier and inverter is called the DC link. The block diagram of a speed controller (often called an inverter) is shown below:

Supply

ECO REFERENCE MANUAL

Rectifier DC Link Inverter

Inverter Block Diagram

3-4

Page 12

ECO REFERENCE MANUAL

The three phase supply is fed into a full wave rectifier which supplies the DC link capacitors. The capacitors reduce the voltage ripple (especially on single phase supplies) and supply energy for short mains breaks. The voltage on the capacitors is uncontrolled and depends on the peak AC supply voltage.

MICROMASTER Eco & MIDIMASTER Eco inverters are available as three phase.

DIAGRAM AND TEST RESULTS

The DC voltage is converted back to AC using Pulse Width Modulation (PWM). The desired waveform is built up by switching the output transistors (Insulated Gate Bipolar Transistors; IGBTs) on and off at a fixed frequency (the switching frequency). By varying the on and off time of the IGBTs the desired current can be generated. The output voltage is still a series of square wave pulses and the inductance of the motor windings results in a sinusoidal motor current. Pulse Width Modulation is shown in the figure below.

CONTROL & REGULATION

The Eco range enables the following improvements to sy stem control and regulation.

• Finer control of system functions as the Eco accurately follows set point s.

• Closed loop process control using a standard Proportional, Integral, Derivative (PID) control loop function.

• Reduced overshoot of pre-set parameters, provides optimised levels of comfort.

• Automatic compensation for system fluctuations - partially blocked filters.

NOISE

Noise reductions can be achieved by reduction in:

• Motor and fan rpm.

• Air flow velocity

• Balance dampers are set in a more open

position.

• Periodic on/off actions create a higher and more irritating noise level than continuous running

4-1

Page 14

ECO REFERENCE MANUAL

WEAR & TEAR

Eco inverters can make possible greatly reduced maintenance and running costs:

• Fewer stop/start sequences means that mechanical stresses are reduced.

• Equipment life is extended, and a smaller number of components require reduced degree of maintenance

• Reduced airflow means reduced cleaning.

• Reduction in replacement of maintenance

consumables such as fan belts, motor bearings and fan bearings.

STARTING TORQUE

torque (Nm)

direct-on-line

EQUIPMENT RATIONALISATION

Using Eco inverters can significantly reduce the number of system components and often enable valuable space to become available:

• Mechanical components which may be eliminated include dampers, actuators, (and outstations by using serial communication).

• Reductions in the use of electrical contactors, control and overload relays, terminals and PID modules can be achieved. Also, control panel complexity is reduced, as is wiring and labour costs.

OUTSTATION CAPABILITY WITH RS485 SERIAL COMMUNICATION

Remote control capability via RS485 serial link using the USS protocol with the ability to control up to 31 inverters via the USS protocol.

6. ENERGY SAVING PROGRAM

ENERGY CONTROL OPTIMIZATION (P077)

This feature provides :

• “Energy Control Optimization” (Eco)

• Automatically increases and decreases motor

voltage in order to search for the minimum power consumption

• Operates when the setpoint speed is reached

• Factory default setting

voltage (V)

frequency (Hz)

The Eco starts to analyse the power consumption of the motor as soon as the motor has reached setpoint speed (i.e. when acceleration is complete).

It then begins to search for the optimum efficiency (lowest power consumption) by slightly lowering or raising the output voltage to the motor.

For example, if the Eco detects that the power consumption is increasing as it is increasing the voltage to the motor, then the control strategy will begin to decrease the output motor voltage in search of the lowest power consumption level. The converse of this will also apply, again to automatically determine the lowest power consumption level.

The Control Mode (P077=4) is set to Energy Control Optimisation as the factory default.

The amount of additional energy saved using this optimisation technique can vary considerably and is dependent on motor loading, motor type and duty cycle. Typical additional savings can be between 2% and 5%.

8. Eco SELECTION CRITERIA - SIZE, TYPE ETC

Generally, drive selection is straightforward, as the motor rating is already known and the speed range requirements are either pre-determined, or easily identified and accomplished. However, when a drive system is selected from first principles, careful consideration may avoid problems in installation and operation, and may also generate significant cost savings.

OVERALL CONSIDERATIONS

• Make sure that the Current rating of the inverter is compatible with the name plate current rating of motor - power rating can be used as a rough guide.

• Check that you have selected the correct operating voltage and that the motor terminals are configured correctly.

• Make sure that the speed range you require is attainable. Operation above normal supply frequency (50 or 60Hz) is usually only possible at reduced power. Operation at low frequency and high torque (not normally a characteristic of fans and pumps) can cause the motor to overheat unless provision is made for additional cooling.

• Do you need to operate with cables longer than 100m, or screened or armoured cables longer than 50m ?. If so, it may be necessary to de-rate the inverter, or fit a choke to compensate for the cable capacitance. See section 14 for motor cable length details.

• The Eco is only intended for use with centrifugal pumps and fans see p 8-8 for further information.

SUPPLY SIDE REQUIREMENTS

SUPPLY TOLERANCE

The inverters are designed to operate on a wide range of supply voltages as follows:

208 - 240 V +/- 10% 380 - 460/480/500 V +/- 10% 525 - 575 V +/- 15%

Inverters will operate over a supply frequency of 47 - 63 Hz.

Many supplies vary outside these levels. For example:

• Supply voltages at the end of long power lines in remote areas can rise excessively in the evening and weekends when large loads are no longer present.

• Industries with locally controlled and generated supplies can have poor voltage regulation and control.

• Power systems in certain parts of the world may not meet the inverter input voltage tolerances.

In all installations, check that the supply will remain within the voltage tolerances stated above. Operation outside of the stated supply levels may cause damage and give unreliable operation.

To achieve maximum reliability and optimum performance, the main power supply to the inverter system must be suited to the inverter. The following points should be considered:

8-1

Page 32

ECO REFERENCE MANUAL

SUPPLY DISTURBANCE

Many supplies are well controlled and remain in tolerance, but are affected by local disturbances. These can cause faulty operation and damage to inverters. In particular, check for:

• Power Factor Correction equipment. Unsuppressed switching of capacitor banks can produce very large voltage transients and is a common cause of inverter damage.

• High power welding equipment, especially resistance and RF welders.

• Other drives, semiconductor heater controllers etc.

The inverter is designed to absorb a high level of supply disturbance - for instance, voltage spikes up to 2kV. However, the above equipment can cause power supply disturbances in excess of this. It will be necessary to suppress this interference - preferably at source - or at least by the installation of an input choke in the inverter supply. EMC filters do not suppress disturbances with this level of energy. Over-voltage protection products such as metal oxide varistors should also be considered in extreme cases.

Damage can also be caused by local supply faults and the effects of electrical storms. In areas where these are expected, similar precautions are recommended.

UNGROUNDED SUPPLIES

Certain installations need to operate with supplies that are isolated from the protective earth (IT supply). This permits equipment to continue to run following a line to earth fault. However, MICROMASTER Eco and MIDIMASTER Eco are designed to normally operate on grounded supplies and are fitted with interference suppression capacitors between the supply and ground. Preventative measures (see below) should be used on ungrounded supplies. Please consult Siemens for further clarification.

LOW FREQUENCY HARMONICS

The inverter converts the AC supply to DC using an uncontrolled diode rectifier bridge. The DC link voltage is close to the peak AC supply voltage, so the diodes only conduct for a short time at the peak of the AC waveform.

EMC FILTER RESTRICTIONS FOR ALL PRODUCTS

The input RFI suppression filters on unearthed supplies since they are designed for earthed supplies only. Many unearthed supplies are only intended for industrial users (particularly 500V ones), and EN61800-3 does not impose any emissions limits in such applications. Therefore a filter may not be required in any case.

The EMC tests have been carried out according to EN61800-3 on earthed supplies. The test results will not be valid for unearthed supplies.

cannot

be used

The current waveform therefore has a relatively high RMS value as a high current flows from the supply for a short time.

For typical harmonic details, refer to Section 15.

MICROMASTER Eco

MICROMASTER can be used on unearthed supplies if connected through an isolating transformer.

Alternatively they may also be connected directly to the unearthed supply, but the inverter may then shut down (F002) if an output earth fault develops.

MIDIMASTER Eco

The 380/500V models are suitable for use on unearthed supplies at a maximum switching frequency of 2kHz (P076 = 6 or 7). This is to prevent the input Y capacitors from overheating in the event of an earth fault on the Eco output.

The MIDIMASTER Eco will continue to operate normally under earth fault conditions at the MIDIMASTER Eco input.

Earth fault monitoring on the input supply, capable of detecting an earth fault on the motor output, is recommended.

ECO REFERENCE MANUAL

This means that the input current waveform consists of a series of low frequency harmonics, and this may in turn cause voltage harmonic distortion, depending on the supply impedance.

Sometimes these harmonics need to be assessed in order to ensure that certain levels are not exceeded. Excessive harmonic levels can cause high losses in transformers, and may interfere with other equipment. In any case, the rating and selection of cabling and protection equipment must take into account these high RMS levels. Some typical measured harmonic levels are shown below.

Three Phase Supplies

Current

In order to calculate the harmonics in a particular supply system it is essential that the supply impedance is known. This is usually stated in terms of fault current levels, transformer size, and installed impedance such as line inductors etc. The addition of input line chokes reduces the level of harmonic currents and also reduces the overall RMS current as well as improving the overall power factor.

Where supplies have very low impedance (such as below 1%) an input inductor is recommended in any case to limit peak currents in the drive.

MOTOR LIMITATIONS

The motor speed is determined mainly by the applied frequency. The motor slows down a little as the load increases and the slip increases. If the load is too great the motor will exceed the maximum torque and stall or ‘pull out’.

The standard induction motor is cooled by a built in fan connected directly to the shaft that runs at motor speed. This is designed to cool the motor at full load and name plate rated speed. If a motor runs at a lower frequency and at full torque

- that is high current not normally an operating

be inadequate. Motor manufacturers generally give the necessary de-rating information, but a typical de-rating curve would limit output torque at zero frequency rising to full output torque capability at 50% of nameplate rated speed (see diagram). Ensure that these limitations are not exceeded for long term operation.

Use the i2t function to help protect the motor (See P074 in parameter descriptions ) or consider using a motor with built in thermal protection such as a thermistor (PTC).

ECO REFERENCE MANUAL

High speed operation of standard motors is usually limited to twice the normal operating speed (i.e. up to 6000 or 7200 rpm) of a two pole motor because of bearing limitations. However, because the motor magnetic flux level will reduce above base speed (because the output voltage is limited to approximately the input voltage) the maximum torque will also fall in inverse proportion to the speed above base speed.

It is not usually possible to operate a fan or pump motor over its base speed since the torque (current) requirement will increase proportionally to the square of the speed.

However, if a motor is connected as a low voltage motor (delta connected motor windings) and operated on a higher voltage inverter, full torque may be obtained up to 1.7 times base frequency if the inverter is correctly set up. Obtain the correct voltage/frequency curve by setting the motor parameters as follows:

LOAD CONSIDERATIONS

The inverter and motor requirements are determined by the speed range and torque requirements of the load. The relationship between speed and torque is different for different loads. Many loads can be considered to be constant torque loads. That is, the torque remains the same over the operating speed range. Typical constant torque loads are compressors, positive displacement pumps and conveyors.

These constant torque loads are generally not suited to the MICROMASTER Eco since it is rated only for variable torque loads such as pumps and fans.

ECO REFERENCE MANUAL

VARIABLE TORQUE APPLICATIONS

Some loads have a Variable Torque characteristic, that is, the torque increases with the speed. Typical variable torque loads are centrifugal pumps and fans. In these applications the load is proportional to the square of the speed, and therefore the power is proportional to the cube of the speed. This means that at reduced speeds there is a great reduction in power and therefore energy saving - a major advantage of variable speed drives applied to pumps and fans. For example, a 10% reduction in speed will give a theoretical 35% reduction on power!

Because the power is greatly reduced, the voltage applied to the motor can also be reduced and additional energy saving achieved. A ‘quadratic’ or ‘pump and fan’ voltage to frequency relationship is a factory default within the MICROMASTER Eco and MIDIMASTER Eco.

It is not generally useful to run pumps or fans above base speed as the power will rise excessively and the fan or pump may become inefficient or damaged.

MIDIMASTER Eco are therefore variable torque rated for pump and fan operation can give an additional capital cost saving in these applications.

Torque - proportional to the square of the speed

OTHER LOADS

Many other loads have non linear or varying torque relationships. The torque requirement of the load should be understood before the inverter and motor is selected.

By comparing the load/speed requirement with the motor capability, the correct motor can be selected. Remember a different pole pair

ENVIRONMENTAL CONSIDERATIONS

The inverter is designed for operation in an HVAC environment. However there are certain limitations which must be considered; the following check list should help:

• Check that the airflow through the inverter will not be blocked by wiring etc. Ensure adequate clearance between cable trunking and the top and bottom ventilation ducts of the inverter.

• Make sure the temperature of the air does not exceed 50°C MICROMASTER Eco or 40°C MIDIMASTER Eco. Remember to allow for any temperature rise inside the enclosure or cubicle.

• The inverters are available with protection levels of IP20 (MICROMASTER Eco), IP21 or IP56 (MIDIMASTER Eco). IP20 and IP21 units need additional protection against dust, dirt, and water.

• The inverter is designed for fixed installation and is not designed to withstand excessive shock and vibration.

• The inverter will be damaged by corrosive atmospheres.

• Protect the unit from dust; dust can build up inside the unit, damage the fans, and prevent proper cooling. Conductive dust, such as metal dust, will damage the unit.

• Give due consideration to Electromagnetic Compatibility (EMC), such as:

1. The inverter should be protected from the

effects of equipment such as Power Factor Correction equipment, Resistance Welding Equipment etc.

2. The inverter should be well grounded.

3. How will the inverter and any control

equipment (contactors, PLCs, relays sensors etc.) interact? Contactor coils should be suppressed using an R-C module. BMS units actuators and sensors should be well earthed.

IP Protection

The IP number defines the level of Ingress Protection (IP) for the particular inverter.

MICROMASTER Eco models have an IP rating of IP20 (US equivalent NEMA 1).

MIDIMASTER Eco models have an IP rating of IP21 (US equivalent NEMA 1) or IP56 (US equivalent NEMA 4/12).

POWER AND MOTOR CONNECTIONS

- MIDIMASTER Eco RANGE

1. Gain access to power and motor terminals by removing the front cover from the inverter (lower-front cover only, for frame size 7).

2. Make sure that the power source supplies the correct voltage and has the necessary current supply capacity. Make sure that the appropriate circuit-breaker (or fuses) with the specified current rating are connected between the power supply and inverter (Refer to Table of recommended fuses and ratings on page 10-7).

3. Feed the cables through the correct glands in the base of the inverter. Secure the cable glands to the inverter and connect the leads to the power and motor terminals.

4. Connect the power input leads to the power

terminals L1, L2, L3 (3 phase) and earth (PE) using a 4-core cable and lugs to suit the cable size.

5. Use a 4-core cable and suitable lugs to connect the motor leads to the motor terminals U, V, W and earth (PE).

6. Tighten all the power and motor terminals: Frame size 4 and 5: Tighten up each of the

power and motor terminal screws to 1.1 Nm. Frame size 6: tighten up each of the power and motor terminal Allen-screws to 3.0 Nm. Frame size 7: Tighten up each of the M12 power and motor terminal nuts to 30 Nm.

Make sure that all the leads are connected correctly and the equipment is properly earthed.

The total length of the motor cable(s) should generally not exceed 100m. If a screened motor cable is used or if the cable channel is well grounded, the maximum length should generally not exceed 50m. Cable lengths above 200m are possible by derating the invertor’s output current or by using additional output reactors (chokes). Refer to table of maximum recommended motor cable lengthsSection 13 and output reactor selection-Section 15.

7. Secure the front cover to the inverter when all connections are complete and before energising.

ratio between the rated motor speeds will be consistent over the full range.

If motor sizes vary to any great extent, this could cause problems at start-up and at low rpm. This is because smaller motors need a higher voltage during start-up, as they have a higher resistance value in the stator.

Additional motor protection (e.g. thermistors in every motor or individual thermal overload relays) is essential in systems with parallel motor operation. This is because the inverter’s internal thermal protection cannot be used, as output current must be programmed to match the overall motor current.

Total motor current consumption must not exceed maximum rated output current.

Parameter P077 should be set to multi motor mode.

The MICROMASTER Eco & MIDIMASTER Eco range can be used to control all types of threephase asynchronous squirrel cage motors.

The voltage and connection method should be taken from the motor nameplate, but as a general rule, larger motors (380/660 volt) are deltaconnected and smaller motors (220/380 volt) are star-connected.

MULTI-MOTOR CONNECTION

The MICROMASTER Eco & MIDIMASTER Eco range can be used to control several motors connected in parallel.

MOTOR OVERLOAD PROTECTION

When operated below rated speed, the cooling effect of fans fitted to the motor shaft is reduced, so that most motors require de-rating for continuous operation at low frequencies. However, variable torque loads such as pumps and fans are generally not heavily loaded at low speeds. To provide motors with additional protection against overheating, a PTC (thermistor) temperature sensor may be fitted to the motor and connected to the inverter control terminals. Note: to enable the motor overload protection trip function, see parameter P087=1.

12. EMC GUIDELINES

EMC

All electronic and electrical equipment generate unwanted signals. These signals can be emitted from the product either via cables that are connected to the product (Input, output, control signals etc.) or via electromagnetic radiation ‘radio transmission’. These signals can be received by other products (via the same routes) and can interfere with the correct operation of the product.

Micromaster

Control

Supply

Micromaster

Control

Supply

Any particular product gives out a certain level of emissions, and has a certain level of immunity to incoming signals from other products. If the immunity of all products is higher than their emissions, there is no problem. If the immunity is lower, severe problems can occur, causing quality problems, damage, or in extreme cases injury.

Electro-magnetic Compatibility (EMC) concerns how equipment works together; Electro-magnetic Interference (EMI) refers to the unwanted signals themselves.

Output

Emissions

Output

Immunity to

Emissions

EMI has become a more serious problem recently as more electronic systems (which may prove to have low immunity) are used in industrial applications, and as power electronic products such as drives, generate high frequency signals which can produce high levels of interference.

ELECTRO-MAGNETIC COMPATIBILITY (EMC)

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

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 Eco and MIDIMASTER Eco 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 of the EMC performance characteristics of the products when they are installed in accordance with the wiring recommendations in the Wiring Guidelines at the end of this section.

ELECTRO-MAGNETIC INTERFERENCE (EMI)

The inverters are designed to operate in an environment where a high level of ElectroMagnetic Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble-free operation. If there are any problems, the following guidelines may prove useful. In particular, grounding of the system at the inverter, as described below, may prove effective. The figures at the end of this section illustrate how filters should be installed and connected.

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

Connect the return earth from motors controlled by the inverter directly to the earth connection (PE) on the associated inverter.

• On the MIDIMASTER Eco, use saw-tooth washers when mounting the inverter and ensure that a good electrical connection is made between the heatsink and the back panel, removing paint if necessary to expose bare metal.

• Wherever possible, use screened leads for connections to the control circuitry. Terminate both the ends of the cable neatly, ensuring that unscreened wires are as short as possible. Use cable glands whenever possible and earth both ends of the screen on the control cable.

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

• Ensure that contactors in the cubicle are suppressed, either with R-C suppressors for AC contactors or ‘flywheel’ diodes for DC contactors, fitted to the coils. Varistor suppressors are also effective. This is particularly important if the contactors are controlled from the output relay on the inverter.

• Use screened or armoured cables for the motor connections and ground the screen at both ends via the cable glands.

• If the drive is to be operated in an Electromagnetic noise-sensitive environment, the RFI filter should be used to reduce the conducted and radiated interference from the inverter. For optimum performance, there should be a good conductive bond between filter and metal mounting plate.

On no account must safety regulations be compromised when installing inverters!

Fitting of Accessory Filter (Frame Sizes 4, 5 and 6, IP56)

The installation procedure is as follows:-

1. Unpack the filter and prepare the connecting cable. Trim the screen back so that it will not obstruct the connection of the cables into the mains input terminals (L1, L2, L3 & E) of the inverter.

unfiltered IP56 Eco unit, then there are mounted studs provided within the IP56 enclosure for installing the recommended class A filter.

Class B EMC Filters cannot be installed within the IP56 Eco unit.

ECO REFERENCE MANUAL

2. Cover the loose strands of the cable screen with either a short length of heat shrink sleeve or some insulation tape. This is to ensure that the screen is tidy and loose strands will not cause a nuisance.

3. Fit the filter to the studs provided in the IP56 case and bolt down.

4. Screw the three power cables and the earth connection into the supply input terminals (L1, L2, L3 and E) of the inverter.

The screen over the cable that leaves the filter is not used in this type of installation. It is only required if the filter is to be fitted to an IP21 rated inverter as an external filter.

PARAMETER TYPES

There are three types of parameters:

True value parameters.

•

For example, setting parameter P003 rampdown time to 10 seconds tells the Eco to take 10 seconds to slow the motor from its normal operating speed to stopped.

Limited range parameters

•

The values themselves are not relevant and only represent the function required. For example:

1. Parameter P199 can only be set to 0 or 1.

2. setting the value to 0 tells the Eco to give access to the basic parameters only.

3. setting the value to 1 gives access to the expert parameters.

ECO REFERENCE MANUAL

‘Read only’ parameters.

• The values of these parameters are factory set and provide the user with information. For instance, parameter P111 is a read only parameter and indicates the inverter’s variable torque power rating in kW.

PARAMETER RANGES

The Eco has three ranges of parameters;

• Display mode

• Basic mode

• Expert mode.
