11

2.3. Safety in installation and maintenance

These warnings are intended for all who work on the drive, motor cable or motor.

Electricity safety

WARNING! Ignoring the instructions can cause physical injury or death, or damage to the equipment.

Only qualified electricians are allowed to install and maintain the drive!

Never work on the drive, motor cable or motor when input power is applied. After disconnecting the input power, always wait for 10 minutes to let the intermediate circuit capacitors discharge before you start working on the drive, motor or motor cable.

Always ensure by measuring with a multimeter (impedance at least 1 Mohm) that:

1. There is no voltage between the drive input phases L1, L2 and L3 and the ground.

2. There is no voltage between terminals + and BR and the ground.

Do not work on the control cables when power is applied to the drive or to the external control circuits. Externally supplied control circuits may carry dangerous voltage even when the input power of the drive is switched off.

Do not make any insulation or voltage withstand tests on the drive.

Be sure the system is properly grounded before applying power. Do not apply AC power before you ensure that all grounding instructions have been followed. Electrical shock can cause serious or fatal injury.

Note:

Even when the motor is stopped, dangerous voltage is present at the power circuit terminals L1, L2, L3 and U, V, W and + and BR.

12

General safety

WARNING! Ignoring the following instructions can cause physical injury or death, or damage to the equipment.

The drive is not field repairable. Never attempt to repair a malfunctioning drive; contact your local ABB representative or

Authorized Service Centre for replacement.

Make sure that dust from drilling does not enter the drive during the installation. Electrically conductive dust inside the drive may cause damage or lead to malfunction.

Ensure sufficient cooling.

2.4. Safety in start-up and operation

These warnings are intended for all who plan the operation, start up or operate the drive.

WARNING! Ignoring the following instructions can cause physical injury or death, or damage to the equipment.

Before adjusting the drive and putting it into service, make sure that the motor and all driven equipment are suitable for operation throughout the speed range provided by the drive. The drive can be adjusted to operate the motor at speeds above and below the speed provided by connecting the motor directly to the power line.

Do not activate automatic fault reset functions if dangerous situations can occur. When activated, these functions reset the drive and resume operation after a fault.

Do not control the motor with an AC contactor or disconnecting device (disconnecting means); use instead the control panel start and stop keys and or external commands (I/O). The maximum allowed number of charging cycles of the DC capacitors (that is, power-ups by applying power) is two per minute.

Note:

When parameter 1103 PRIMARY COMMAND SOURCE MODE is not set to 1 or 2, the stop key on the control panel will not stop the drive. To stop the drive open terminal 2 of the drive control terminals.

The ACS250 variable speed drive is intended for professional installation and commissioning into complete equipment or systems as part of a fixed installation. If installed incorrectly it may present a safety hazard. The ACS250 uses high voltages and currents, carries a high level of stored electrical energy, and is used to control mechanical plant that may cause injury. Close attention is required to system design and electrical installation to avoid hazards in either normal operation or in the event of equipment malfunction. Only qualified electricians are allowed to install and maintain this product.

System design, installation, commissioning and maintenance must be carried out only by personnel who have the necessary training and experience. They must carefully read this safety information and the instructions in this Guide and follow all information regarding transport, storage, installation and use of the ACS250, including the specified environmental limitations.

Do not perform any flash test or voltage withstand test on the ACS250. Any electrical measurements required should be carried out with the ACS250 disconnected.

Electric shock hazard! Disconnect and ISOLATE the ACS250 before attempting any work on it. High voltages are present at the terminals and within the drive for up to 10 minutes after disconnection of the electrical supply. Always ensure by using a suitable multimeter that no voltage is present on any drive power terminals prior to commencing any work.

Where supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have elapsed after turning off the supply.

Ensure correct grounding connections. The ground cable must be sufficient to carry the maximum supply fault current which normally will be limited by the fuses. Suitably rated fuses should be fitted in the mains supply to the drive, according to any local legislation or codes.

Do not carry out any work on the drive control cables when power is applied to the drive or to the external control circuits.

Within the European Union, all machinery in which this product is used must comply with the Machinery Directive 2006/42/EC,

Safety of Machinery. In particular, the machine manufacturer is responsible for providing a main switch and ensuring the electrical equipment complies with EN60204-1.

The level of integrity offered by the ACS250 control input functions – for example stop/start, forward/reverse and maximum speed is not sufficient for use in safety-critical applications without independent channels of protection. All applications where malfunction could cause injury or loss of life must be subject to a risk assessment and further protection provided where needed.

The driven motor can start at power up if the enable input signal is present.

The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 10 minutes before starting any work on it. Never carry out any work on the Drive, Motor or Motor cable when the input power is still applied.

The ACS250 can be programmed to operate the driven motor at speeds above or below the speed achieved when connecting the motor directly to the mains supply. Obtain confirmation from the manufacturers of the motor and the driven machine about suitability for operation over the intended speed range prior to machine start up.

Do not activate the automatic fault reset function on any systems whereby this may cause a potentially dangerous situation.

The ACS250 has an Ingress Protection rating of IP20 or IP66 depending on the model. IP20 units must be installed in a suitable enclosure.

ACS250s are intended for indoor use only.

When mounting the drive, ensure that sufficient cooling is provided. Do not carry out drilling operations with the drive in place, dust and metal shavings from drilling may lead to damage.

The entry of conductive or flammable foreign bodies should be prevented. Flammable material should not be placed close to the drive

Relative humidity must be less than 95% (non-condensing).

Ensure that the supply voltage, frequency and number of phases correspond to the rating of the ACS250 as delivered.

Never connect the mains power supply to the Output terminals U, V, W.

Do not install any type of automatic switchgear between the drive and the motor

Wherever control cabling is close to power cabling, maintain a minimum separation of 4 in. (100 mm) and arrange crossings at 90 degrees

4.3. Guidelines for Enclosure Mounting – IP20 Units

Installation should be in a suitable enclosure, according to EN60529 or other relevant local codes or standards.

Enclosures should be made from a thermally conductive material.

Where vented enclosures are used, there should be free space clearance above and below the drive to ensure good air circulation – see the diagram below for minimum free space clearance. Air should be drawn in below the drive and expelled above the drive.

In any environments where the conditions require it, the enclosure must be designed to protect the ACS250 against ingress of airborne dust, corrosive gases or liquids, conductive contaminants (such as condensation, carbon dust, and metallic particles) and sprays or splashing water from all directions.

High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure.

The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to allow air to circulate through the drive heatsink. ABB Drives recommend the following minimum mounting clearance requirements for drives mounted in non-ventilated metallic enclosures:-

4.5. Guidelines for Mounting Enclosed Units

Before mounting the drive, ensure that the chosen location meets the

environmental condition requirements for the drive shown in section 12.1

The drive must be mounted vertically, on a suitable flat surface

The minimum mounting clearances as shown in the table below must be observed

The mounting site and chosen mountings should be sufficient to support the weight of the drives

The Enclosed ACS250s can be installed side-by-side with their heatsink flanges touching. This gives adequate ventilation space between drives.

If the ACS250 is to be installed above another drive or any other heatproducing device, the minimum vertical spacing (X) is 150mm (5.9 inches) above and below.

5. Power Wiring

5.1. Grounding the Drive

This manual is intended as a guide for proper installation. ABB Drives Ltd cannot assume responsibility for the compliance or the non-compliance to any code, national, local or otherwise, for the proper installation of this drive or associated equipment.

A hazard of personal injury and/or equipment damage exists if codes are ignored during installation.

This ACS250 contains high voltage capacitors that take time to discharge after removal of the main supply. Before working on the drive, ensure isolation of the main supply from line inputs. Wait ten (10) minutes for the capacitors to discharge to safe voltage levels. Failure to observe this precaution could result in severe bodily injury or loss of life.

Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved should install, adjust, operate, or service this equipment. Read and understand this manual and other applicable manuals in their entirety before proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.

5.1.2. Grounding Guidelines

The ground terminal of each ACS250 should be individually connected DIRECTLY to the site ground bus bar (through the filter if installed).

ACS250 ground connections should not loop from one drive to another, or to, or from any other equipment. Ground loop impedance must confirm to local industrial safety regulations. To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections.

The drive Safety Ground must be connected to system ground. Ground impedance must conform to the requirements of national and local industrial safety regulations and/or electrical codes. The integrity of all ground connections should be checked periodically.

5.1.3. Protective Earth Conductor

The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductor.

5.1.4. Safety Ground

This is the safety ground for the drive that is required by code. One of these points must be connected to adjacent building steel (girder, joist), a floor ground rod, or bus bar. Grounding points must comply with national and local industrial safety regulations and/or electrical codes.

The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this terminal (drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to the safety ground terminal.

5.1.5. Motor Ground

The motor ground must be connected to one of the ground terminals on the drive.

5.1.6. Ground Fault Monitoring

As with all inverters, a leakage current to earth can exist. The ACS250 is designed to produce the minimum possible leakage current while complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching frequency, the earth connections used and the type of RFI filter installed. If a GFCI (Ground Fault Current interrupter) is to be used, the following conditions apply: -

The device must be suitable for protecting equipment with a DC component in the leakage current

Individual GFCI’s should be used for each ACS250

The ACS250 product range has input supply voltage surge suppression components fitted to protect the drive from line voltage transients, typically originating from lightening strikes or switching of high power equipment on the same supply.

5.2. Wiring Precautions

Connect the ACS250 according to sections 5.3 and 5.4, ensuring that motor terminal box connections are correct. There are two connections in

general: Star and Delta. It is essential to ensure that the motor is connected in accordance with the voltage at which it will be operated. For

more information, refer to section 5.5.

Type MC continuous corrugated aluminium armour cable with symmetrical grounds or shielded power cable is recommended for the motor cables if metallic conduit is not used.

The power cables must be rated for 75˚C (167˚F).

5.2.1. Compatibility with IT (ungrounded) and corner-grounded TN systems

WARNING! EMC filters should not be used when installing the drive on an IT system (an ungrounded power system or highresistance-grounded power system, otherwise the system will be connected to ground potential through the EMC capacitors. This may cause danger or damage to the EMC filter.

If you have an IT (ungrounded) system or corner-grounded TN system, disconnect the internal Varistor screw as shown below.

5.4. Drive & Motor Connections

For 1 phase supply, power should be connected to L1/L, L2/N. For 3 phase supplies power should be connected to L1, L2, L3. Phase sequence is not important. The Motor should be connected to U, V, W

For drives that have a dynamic brake transistor an optional external braking resistor will need be connected to +DC and BR when required.

The brake resistor circuit should be protected by a suitable thermal protection circuit. The “–DC”, “+” and “BR” connections are blanked off by plastic tabs when sent from the factory. The plastic tabs can be removed if/when required.

5.5. Motor Terminal Box Connections

Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the nameplate of the motor. This operational voltage is normally selected when installing the motor by selecting either STAR or DELTA connection. STAR always gives the higher of the two voltage ratings. Example Motor nameplate shown below (380V Delta illustrated):

5.6. Using the REV/Off/FWD Selector Switch (IP66 Switched Version Only)

By adjusting the parameter settings the ACS250 can be configured for multiple applications and not just for Forward or Reverse.

This could typically be for Hand/Off/Auto applications (also known as Local/Remote) for Industrial fan and pump industries.

0 Rpm

The V/f characteristic is defined by several parameters as follows :-

Parameter 9905 : Motor Rated Voltage

Parameter 9907 : Motor Rated Frequency

The voltage set in parameter 9905 is applied to the motor at the frequency set Under normal operating conditions, the voltage is linearly reduced at any point below the motor rated frequency to maintain a constant motor torque output as shown by the line ‘A’ on the graph.

By using parameters parameter 2610 and 2611, the voltage to be applied at a particular frequency can be directly set by the user, thereby altering the V/F characteristic.

Reducing the voltage at a particular frequency reduces the current in the motor and hence the torque and power, hence this function can be used in fan and pump applications where a variable torque output is desired by setting the parameters as follows :-

Parameter 2610 = 9905 / 4

Parameter 2611 = 9907 / 2

This function can also be useful if motor instability is experienced at certain frequencies, if this is the case increase or decrease the voltage (Parameter 2610) at the speed of instability (Parameter 2611).

For applications requiring energy saving, typically HVAC and pumping, the energy optimiser (Parameter 2601) parameter can be enabled. This automatically reduces the applied motor voltage on light load.

10.6. Motor Thermistor Connection

1 : + 24 Volt

4 : External Trip

The motor thermistor should be connected between terminals 1 and 4 as shown. A setting of Parameter 9902 where Digital Input 3 is programmed for ‘External Trip’ must be used. The current flow through the thermistor is automatically controlled to prevent a failure.

Depending on the operating mode of the drive – some parameters cannot be changed while the drive is enabled for example.

Modbus RTU supports sixteen bit integer values, hence where a decimal point is used in the drive parameter; the register value will be multiplied by a factor of ten, E.g. Read Value of parameter 2008 MAXIMUM FREQUENCY / SPEED LIMIT = 500, therefore this is 50.0Hz

Also Refer to section 12.5 for Output current Derating Information.

12.2. Input/Output Current ratings and fuses

The following tables provide the output current rating information for the various ACS250 models. ABB Drives always recommend that selection of the correct ACS250 is based upon the motor full load current at the incoming supply voltage.

Cable dimensioning for nominal rated currents is shown in the table below together with the corresponding fuse types for short-circuit protection of the input power cable.

The rated fuse currents given in the table are the maximums for the mentioned fuse types. If smaller fuse ratings are used, check that the fuse rms current rating is larger than the nominal input current. If 150% output power is needed, multiply nominal input current by 1.5.

Check that the operating time of the fuse is below 0.5 seconds. The operating time depends on the fuse type, the supply network impedance as well as the cross sectional area, material and length of the supply cable. In case the 0.5 seconds operating time is exceeded with the gG or T fuses, ultra rapid (aR) fuses in most cases reduce the operating time to an acceptable level.

Note: Larger fuses must not be used when the input power cable is selected according to this table.

12.5.4. Example of applying Derating Factors

A 5Hp, 400V/460V IP66 drive is to be used at an altitude of 2000 metres above sea level, with 12kHz switching frequency and 45°C ambient temperature.

From the table above, we can see that the rated current of the drive is 9.5 Amps at 40°C,

Firstly, apply the swicthing frequency derating, 12kHz, 25% derating

9.5 Amps x 75% = 7.1 Amps

Now, apply the derating for higher ambient temperature, 2.5% per °C above 40°C = 5 x 2.5% = 12.5%

7.1 Amps x 87.5% = 6.2 Amps

Now apply the derating for altitude above 1000 metres, 1% per 100m above 1000m = 10 x 1% = 10%

7.9 Amps x 90% = 5.5 Amps continuous current available.

If the required motor current exceeds this level, it will be neccesary to either

- Reduce the switching frequency selected

- Use a higher power rated drive and repeat the calculation to ensure sufficient output current is available.

12.6. Mains Line input Reactors

An optional Line reactor is recommended to be installed on drives where any of the following site conditions occur:- o The incoming supply impedance is low or the fault level / short circuit current is high. o If the transformer kVA rating is more than 10x the kVA rating of the drive or ensure that the per drive source

Impedance is less than 0.5%. o The supply is prone to dips or brown outs. o An imbalance exists on the supply (3 phase drives). o The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes). o Reduction in Harmonics generated by the drive.

In all other installations, it is good practice to install a line reactor as added protection of the drive against power supply faults.

12.6.1.

Selecting a Line Reactor

The chosen Line reactor should be in the region of 3% impedance; higher values can be used but will result in less voltage (and less torque) to the motor as full load is reached.

The continuous current rating should be at least the value of the drives input current rating, with a peak current rating of at least 2 times the continuous current rating.

Motor thermal overload protection trip. The drive has tripped after delivering >100% of value in 9906 for a period of time to prevent damage to the motor.

Fault occurs immediately on drive enable or run command

Check the output wiring connections to the motor and the motor for short circuits phase to phase and phase to earth.

Fault occurs during motor starting

Check the motor is free to rotate and there are no mechanical blockages. If the motor has a brake fitted, check the brake is releasing correctly. Check for the correct star-delta motor wiring. Ensure the motor nameplate current is correctly entered in parameter

9906. Increase the acceleration time in parameter 2202. Reduce the motor boost voltage setting in parameter 2603

Fault occurs when motor operating at constant speed

Investigate overload or malfunction.

Fault occurs during motor acceleration or deceleration

The accel/decel times are too short requiring too much power. If parameter 2202 or 2203 cannot be increased, a bigger drive may be required

Ensure the correct motor nameplate current value is entered in parameter 9906. Check for correct Star or Delta wiring configuration. Check to see when the decimal points are flashing (which indicates the output current > parameter 9906 value) and either increase acceleration ramp (parameter 2202) or decrease motor load. Check the total motor cable length is within the drive specification. Check the load mechanically to ensure it is free, and that no jams, blockages or other mechanical faults exist

For Other Brake Resistors

Ensure the resistance of the brake resistor is equal to or greater than the minimum value

for the relevant drive shown in the table in section 12.2. Use an external thermal

protection device for the brake resistor. In this case, parameter 2020 may be set to 2

Check the wiring to motor and the motor for phase to phase and phase to earth short circuits. Disconnect the motor and motor cable and retest. If the drive trips with no motor connected, it must be replaced and the system fully checked and retested before a replacement unit is installed.

Check the supply voltage is within the allowed tolerance for the drive. If the fault occurs on deceleration or stopping, increase the deceleration time in parameter 2203 or install a suitable brake resistor and activate the dynamic braking function with parameter 2020

The incoming supply voltage is too low. This trip occurs routinely when power is removed from the drive. If it occurs during running, check the incoming power supply voltage and all components in the power feed line to the drive.

The drive is too hot. Check the ambient temperature around the drive is within the drive specification. Ensure sufficient cooling air is free to circulate around the drive.

Increase the panel ventilation if required. Ensure sufficient cooling air can enter the drive, and that the bottom entry and top exit vents are not blocked or obstructed.

Trip occurs when ambient temperature is less than -10°C. The temperature must be raised over -10°C in order to start the drive.
