Introduction vacon • 5

1. I

The VACON® NXP System Drive is a comprehensive configured common DC bus drive line up for heavy-industry needs where round-the-clock activity is required leaving little time for maintenance.

All sections are grouped depending on their functionality, making it possible to plan each installation phase according to your requirements. The engineered sections slot in alongside each other allowing you to arrange integrated transport splits to save space. Alternatively, you can add extra transport sections to speed up installation. All larger modules have slide-out mechanics for easier set-up and maintenance.

The VACON® NXP System Drive is built to last. Items such as busbar systems and high/low power devices are separated into individual compartments away from each other. This means that, if an issue occurs, it is compartmentalized and doesn’t cause widespread failure helping to reduce lifetime and maintenance costs.

1.7 Storage

If the system drive is to be kept in store before use, make sure that the ambient conditions are acceptable:

• Storing temperature –40…+70 °C

• Relative humidity <95%, no condensation

The environment should also be free from dust. If there is dust in the air, the drive should be well protected to make sure dust does not get into the drive.

If the drive is to be stored during longer periods, the power should be connected to the drive once in 24 months and kept on for at least 2 hours. If the storage time exceeds 24 months the electrolytic DC capacitors need to be charged with caution. Therefore, such a long storage time is not recommended.

If the storing time is much longer than 24 months, the recharging of the capacitors has to be carried out so that the possible high leakage current through the capacitors is limited. The best alternative is to use a DC power supply with adjustable current limit. The current limit has to be set for example to 300-500 mA and the DC power supply has to be connected to the B+/B- terminals (DC supply terminals).

DC voltage must be adjusted to nominal DC voltage level of the unit (1.35xUn AC) and supplied at least for 1 hour.

If DC voltage is not available and the unit has been stored de-energized much longer than 1 year, consult factory before connecting power.

1.8 Lifting and moving the cabinet sections

For transport, the system drive is split into smaller sections. The cabinet sections are delivered either in a wooden box or a wooden cage. The cabinets are transported vertically. Always refer to shipping marks for more detailed information. To lift the cabinet sections, use lifting equipment capable of handling the weight of the cabinets.

There are lifting beams on the top of the cabinets. Use the beams to lift and to move the cabinets to the required location.

Figure 1. Lifting the cabinet sections

Moving of the cabinets on site can be carried out as follows by a forklift truck, a hoist or on rollers:

• Lower the package onto a level base

• Remove the package covering only at the site of installation

• Low, narrow or convoluted transport routes may require removal of the pallet prior to movement

• Move packages in the upright position only

Figure 2. Moving the cabinet sections

Switchgear parts can easily topple backwards when manoeuvring on rollers or manual trolleys because their centre of gravity is typically located high up at the rear of the unit.

vacon • 12 Safety

9000.emf

2.1 Warnings

The components of the power unit and all cabinet mounted devices are live when the drive is connected to mains potential. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury.

The motor terminals U, V, W, the DC bus/brake resistor terminals and all other mains devices are potentially live when the drive is connected to mains, even if the motor is not running.

After disconnecting the AC drive from the mains, wait until the fan stops and the indicators on the keypad go out (if no keypad is attached see the indicators on the cover). Wait 5 more minutes before doing any work on the connections of the drive. Do not open the cabinet door before this time has expired. After expiration of this time, use measuring equipment to absolutely ensure that no voltage is present. Always

ensure the absence of voltage before starting any electrical work! The control I/O-terminals are isolated from the mains potential. However, the relay

outputs and other I/O-terminals may have a dangerous control voltage present even

when the drive is disconnected from mains.

Before connecting the drive to mains make sure that the drive front and cable covers as well as the cabinet doors are closed.

Wear protective gloves when you do mounting, cabling or maintenance operations. There can be sharp edges in the AC drive that can cause cuts.

Safety vacon • 13

13006.emf

2.2 Cautions

VACON® AC drives are meant for

fixed installations only

Do not perform any measurements when the AC drive is connected to mains.

The touch current of VACON® AC drives exceeds 3.5 mAAC. According to standard EN61800-5-1, a reinforced protective ground connection must be ensured. See

Chapter 2.3.

If the drive is used as a part of a machine, the machine manufacturer is responsible for providing the machine with a supply disconnecting device (EN60204-1).

Only spare parts delivered by Danfoss can be used.

At power-up, power brake or fault reset the motor will start immediately if the start signal is active, unless the pulse control for Start/Stop logic has been selected. Futhermore, the I/O functionalities (including start inputs) may change if parameters, applications or software are changed. Disconnect, therefore, the motor if an unexpected start can cause danger.

The motor starts automatically after automatic fault reset if the autoreset function is activated. See the Application Manual for more detailed information.

Prior to measurements on the motor or the motor cable, disconnect the motor cable from the drive.

Do not touch the components on the circuit boards. Static voltage disharge may damage the components.

Check that the EMC level of the AC drive corresponds to the requirements of the supply network.

Make sure that the cooling is sufficient. If the AC drive becomes frequently too hot, the lifetime of the drive will be shorter than usually.

2.3 Grounding and ground fault protection

CAUTION!

The AC drive must always be grounded with a grounding conductor connected to the grounding terminal marked with:

The touch current of the AC drive exceeds 3.5 mA AC. According to EN61800-5-1, one or more of the following conditions for the associated protective circuit shall be satisfied:

A fixed connection and

• the protective grounding conductor shall have a cross-sectional area of at least 10 mm2 Cu or 16 mm2 Al, or

• an automatic disconnection of the supply in case of discontinuity of the protective grounding conductor, or

• provision of an additional terminal for a second protective grounding conductor of the same cross-sectional area as the original protective grounding conductor.

Table 5. Protective grounding conductor cross-section

Cross-sectional area of phase conductors (S)

[mm2]

≤16

16<S≤35

35<

Minimum cross-sectional area of the corre-

sponding protective grounding conductor

[mm2]

The values above are valid only if the protective grounding conductor is made of the same metal

as the phase conductors. If this is not so, the cross-sectional area of the protective grounding

conductor shall be determined in a manner which produces a conductance equivalent to that

which results from the application of this table.

The cross-sectional area of every protective grounding conductor which does not form part of the supply cable enclosure shall, in any case, be no less than:

• 2.5 mm2 if mechanical protection is provided or

• 4 mm2 if mechanical protection is not provided. For cord-connected equipment, provisions shall be made so that the protective grounding conductor in the cord shall, in the case of failure of the strain-relief mechanism, be the last conductor to be interrupted.

However, always follow the local regulations for the minimum size of the protective grounding conductor.

NOTE! Due to the high capacitive currents present in the AC drive, fault current protective switches

may not function properly.

Do not perform any voltage withstand tests on any part of the AC drive. There is a certain procedure according to which the test shall be performed. Ignoring this procedure may result in a damaged product.

4.2 Preparing the installation site

Before starting the installation work make sure that the level of the floor is within acceptable limits. The maximum deviation from the basic level can be no more than 5 mm over a 3 m distance. The maximum acceptable height difference between cabinet front and rear edges should be within +2/-0 mm limit.

4.2.1 Free space around the cabinet

Enough space must be left above and in front of the cabinet to ensure sufficient cooling and space for maintenance.

It is recommended to leave at least 200 mm above and 1000 mm in front of the cabinets. Also make sure that the temperature of the cooling air does not exceed the maximum ambient

temperature of the drives.

4.3 Mounting the cabinets

The cabinet should always be fixed to the floor or to the wall. Depending on installation conditions, the cabinet sections can be fixed in different ways. There are holes in the front and back corners which can be used for fixing. Additionally, the rails on the top of the cabinet have fixing lugs for fixing the cabinet to the wall or to another cabinet.

4.3.1 Fixing the cabinet to the floor and wall

If the cabinet is installed against a wall, fix the top of the cabinet to the wall (1) and the front corners to the floor (2) with bolts.

If bottom-only fixing is used, fix the cabinet to the floor in the front (2) and in the back (3) with bolts. Fix all the cabinet sections in the same way.

4.6 Cabling

Before connecting any cables, use a multimeter to check that the cables to be connected are not live.

4.6.1 Grounding

PE conductors are connected to the PE busbar. The PE busbars in each section are connected (see Figure 15 on page 34) and the PE busbars must be connected to ground.

See the grounding and ground fault protection instructions in Chapter 2.3.

4.6.2 Mains and motor connection

The power supply terminals can be reached through the bottom part of the cabinet. The mains cables are connected to terminals L1, L2 and L3 on the main input section (see Figure 19 on page 38). The motor cables are connected to inverter section terminals marked with U, V and W. Make openings for the cables in the grommets on the bottom of the cabinet and lead through the cables. Use cable clamps to fix the cables.

Use cables with a temperature rating of at least +70°C. As a rule of thumb, cables and fuses can be dimensioned according to the frequency converter nominal output current, which you can find on the rating plate. Dimensioning according to the output current is recommended because the frequency converter input current never significantly exceeds the output current.

4.6.3 EMC grounding

For the EMC levels C1 and C2, it is necessary to have a 360º grounding of the shield on both ends of the motor cable. The EMC grounding clamps must be suited to the output cable diameter to give a 360º contact with the cables. To make a 360° connection with the grounding clamp, expose the shield of the motor cables.

Figure 26. 360º grounding

4.6.4 Installation of ferrite rings (+OCM) on the motor cable

Route only the motor phase conductors through the ferrite rings. Do not route the PE/ground wire through the ferrite rings. Leave the cable screen below and outside the rings. Mount the PE/ground wire or pigtail on the ground busbar.

In case of parallel motor cables, reserve an equal amount of ferrite ring sets for each cable. Route all the phase conductors of one cable through one set of rings.

The delivery consists of fixed sets of ferrite rings (option). When ferrite rings are used to attenuate the risk of bearing damage, always use two ferrite ring sets per motor cable.

NOTE! The ferrite rings are only additional protection. The basic protection against bearing currents is an insulated bearing.

4.6.5 Control connections

The control unit of the AC drive consists roughly of the control board and additional boards connected to the five slot connectors (A to E) of the control board. The control board is connected to the power unit through a D-connector or fibre optic cables.

Usually, when the frequency converter is delivered from the factory, the control unit includes at least the standard compilation of two basic boards (I/O board and relay board) which are normally installed in slots A and B.

The control board can be powered externally (+24 V, ±10%) by connecting the external power source to either of the bidirectional terminals. This voltage is sufficient for parameter setting and for keeping the fieldbus active.

The tightening torques for the control unit terminals:

• Relay and thermistor terminals (screw M3): 0.5 Nm.

• Other terminals (screw M2.6): 0.2 Nm.

For more detailed cabling instructions, see the corresponding user manual (see Chapter 1.5).

4.6.6 Auxiliary low-voltage connections

The auxiliary low-voltage connections between cabinets can be done with wiring or with busbars. For transport, the wires between two separately transported cabinets are disconnected from the

terminals. The wiring diagrams for the connections are delivered with the system drive. Auxiliary low-voltage busbars (Auxigaine) are available as an option. In this case, the busbars of two

cabinets are connected with quick-connect bridge connectors. The bridge connectors are installed by simply pressing them into place.

5.1 Warranty

Only manufacturing defects are covered by the warranty. The manufacturer assumes no responsibility for damages caused during or resulting from transport, receipt of the delivery, installation, commissioning or use.

The manufacturer shall in no event and under no circumstances be held responsible for damages and failures resulting from misuse, wrong installation, unacceptable ambient temperature, dust, corrosive substances or operation outside the rated specifications.

Neither can the manufacturer be held responsible for consequential damages. The Manufacturer's warranty period is 18 months from the delivery or 12 months from the

commissioning whichever expires first (Danfoss general terms and conditions of sale). The local distributor may grant a warranty time different from the above. This warranty time shall

be specified in the distributor's sales and warranty terms. Danfoss assumes no responsibility for any other warranties than that granted by Danfoss itself.

In all matters concerning the warranty, please contact your distributor first.

5.2 Maintenance

All technical devices, drives as well, need a certain amount of care-taking and failure preventive maintenance. To maintain trouble-free operation of the VACON® drives, environmental conditions, as well as load, line power, process control, etc. have to be within specifications, determined by manufacturer.

If all conditions are in accordance with the manufacturer's specifications, there are no other concerns, but to provide a cooling capacity high enough for the power- and control circuits. This requirement can be met by making sure, that the cooling system works properly. Operation of cooling fans and cleanness of the heat sink should be verified regularly.

Regular maintenance is recommended to ensure trouble free operation and long lifetime of the VACON® drives. At least the following things should be included in the regular maintenance.

Table 15. Maintenance schedule

Interval Maintenance

12 months (if unit is stored) Reform the capacitors

Check the tightening torques of the input and output terminals

6-24 months (depending on

environment)

5-7 years

and I/O terminals. Clean the cooling tunnel. Check operation of the cooling fan, check for corrosion on terminals, busbars and other surfaces.

Change the cooling fans:

• Cabinet fans

• Drive fans

• LCL filter fans

5-10 years Change the DC-link capacitors if DC voltage ripple is high.

It is also recommended to record all actions and counter values with dates and time for follow up of maintenance.

ECHNICAL INFORMATION

6.1 Control and interface

Speed and/or torque control functions are available in the drive. Speed and/or torque reference as well as command word is generated by the overriding line control system and individually transmitted to each drive either via fieldbus or hardwired signals. The drive transmits selected actual values as well as status words back to the line control system.

6.1.1 Control without speed feedback (open loop)

• Speed error in steady state typically <0.5%

• Torque rise time <10 ms

• Torque error in steady state typically <3%

• Suitable also for multimotor configuration

6.1.2 Control with speed feedback (closed loop)

Full torque control at zero speed cannot be maintained without speed feedback. When a speed error of less than 0.5% or full torque control at all speeds is required, motor control based on feedback from an encoder is a necessity. This capability is incorporated into the VACON® NXP drive. In addition to the current measurement system used, the NXP drive utilizes feedback values from the encoder to determine the motor state. The enhanced microprocessor provided with the NXP drive is capable of calculations every 150 microseconds. This control can be used for applications requiring high precision, such as sectional drives.

• Speed error in steady state typically <0.01% (pulse encoder type dependent)

• Pulse encoder: 250-5000 ppr at 5, 12 or 24 V (option board dependent)

• Torque rise time <10 ms

• Torque error in steady state typically <3%

6.2 Load definitions

The drives are normally selected based on the load definition shown in the drive list, where:

•

= minimum speed [RPM], beginning of the continuous constant torque load speed

min

range

•

= base speed [RPM], end of the continuous constant torque load speed range (and

base

beginning of the continuous constant power load speed range)

•

= maximum speed [RPM], end of the continuous constant power load speed range (also

max

maximum allowed motor speed)

•P [

] = base power [kW], motor shaft power at the end of the continuous constant torque

base

load speed range (also motor shaft power of the continuous constant power load speed range)

•T [

] = base torque [Nm], motor shaft torque of the continuous constant torque load

base

speed range (also motor shaft torque at the beginning of the continuous constant power load speed range)

•

= overload [%], short time maximum load, 1 min. / 10 min. (100% = no overload)

NOTE! Load is defined based on the information received. Danfoss is not responsible for verifying that the information is sufficient and accurate.

There are various possibilities to define the load curve. Below are some examples.

Some constant power drives require less overload at max speed than at lower speeds. It is therefore possible to set the relative overload at base speed higher than the relative overload at maximum speed, i.e. OL(

base

This will decrease the size of the motor when/if thermal loadability is not the dimensioning limit.
