Safety and operating instructions

for drive power converters

(as per: Low Voltage Directive 2006/95/EEC )

1. General During operation, drive power converters may, depending on their

protection class, have live, bare, moving or rotating parts or hot surfaces.

Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of serious personal injury or material damage.

Further information can be found in this documentation. All transportation, installation and initialisation and maintenance

work must be carried out by qualified personnel (comply with IEC 364, CENELEC HD 384, DIN VDE 0100, IEC 664 and DIN VDE 0110, and national accident prevention regulations).

For the purposes of these basic safety instructions, qualified personnel are persons who are familiar with the assembly, installation, commissioning and operation of this product and who have the relevant qualifications for their work.

2. Proper use in Europe

Drive power converters are components intended for installation in electrical systems or machines.

When installed in machines, the drive power converter cannot be commissioned (i.e. commencement of the proper use) until it has been ensured that the machine meets the provisions of the EC Directive 2006/42/EEC (Machine Directive); EN 60204 must also be complied with.

Commissioning (i.e. implementation of the proper use) is only permitted when the EMC directive (2004/108/EEC) is complied with.

Drive power converters with a CE label meet the requirements of the Low Voltage Directive 2006/95/EEC. The harmonised standards for drive power converters stated in the declaration of conformity are used.

Technical data and information for connection conditions can be found on the rating plate and in the documentation, and must be complied with.

The drive power converters may only be used for safety functions which are described and explicitly approved.

3. Transport, storage

Information regarding transport, storage and correct handling must be complied with.

4. Installation

The installation and cooling of the equipment must be implemented according to the regulations in the corresponding documentation.

The drive power converter must be protected against impermissible loads. Especially during transport and handling, components must not be deformed and/or insulation distances must not be changed. Touching of electronic components and contacts must be avoided.

Drive power converters have electrostatically sensitive components, which can be easily damaged by incorrect handling. Electrical components must not be mechanically damaged or destroyed (this may cause a health hazard!).

5. Electrical connection

When working on live drive power converters, the applicable national accident prevention regulations must be complied with (e.g. BGV A3, formerly VBG 4).

The electrical installation must be implemented as per the applicable regulations (e.g. cable cross-section, fuses, earth lead connections). Further instructions can be found in the documentation.

Information regarding EMC-compliant installation – such as shielding, earthing, location of filters and installation of cables – can be found in the drive power converter documentation. These instructions must be complied with even with CE marked drive power converters. Compliance with the limit values specified in the EMC regulations is the responsibility of the manufacturer of the system or machine.

6. Operation

Systems where drive power converters are installed must be equipped, where necessary, with additional monitoring and protective equipment as per the applicable safety requirements, e.g. legislation concerning technical equipment, accident prevention regulations, etc.

The parameterisation and configuration of the drive power converter must be selected so that no hazards can occur.

All covers must be kept closed during operation.

7. Maintenance and repairs

After the drive power converter is disconnected from the power supply, live equipment components and power connections should not be touched immediately, because of possible charged capacitors. Observe the applicable information signs located on the drive power converter.

Further information can be found in this documentation.

These safety instructions must be kept in a safe place!

NORDAC SK 700E Operating Manual

1 General information

The series NORDAC SK 700E is the follow-on development of the proven vector series. These devices are characterised by the high modularity and excellent control characteristics.

These devices are provided with non-sensor vector current control system which constantly ensures an optimised voltage-tofrequency ratio in combination with a motor model of an three-phase asynchronous motor. This has the following significance for the drive: Peak start-up and overload torques at constant speed.

Due to its modular construction, the variously combinable technology units, customer units and special extension units, this device series is suitable for all possible applications.

Devices for constant load:

Due to the numerous setting options, these inverters are capable of controlling all three-phase motors. The performance range goes from 1.5kW to 22kW (3~ 380V...480V) with an integrated line filter and from 30kW to 132kW (3~ 380V...480V) with optional external line filter. The overload capacity of these devices is 200% for 3.5 seconds and 150% for 60 seconds.

Device for quadratically increasing loads SK 700E-163-340-O-VT:

In the performance range 160kW (3~ 380V...480V) a variant for quadratically increasing load is available. This load profile is typical for fans and various pump applications. In contrast to the devices used for constant load torque, the overload capacity here is limited to 125%.

NOTE: The SK 700E with the performance range 30kW to 160kW varies in some technical details from the lower

performance devices. Details can be found in this manual.

This manual is based on the device software V3.4 Rev4 (P707) for the SK 700E. If the frequency inverter used has a different version, this may lead to some differences. If necessary, you can download the current manual from the Internet (http://www.nord.com/)

The most important amendments in comparison with edition 3910 are the correction of errors and amendments associated with UL certification.

1.1 Overview

Properties of the basic device:

 Heavy starting torque and precise motor speed control setting with sensorless current/vector control.  Can be mounted next to each other without additional spacing  Permissible environmental temperature range: 0 to 50°C (please refer to technical data)  Integrated line filter for limit curve A as per EN 55011 (up to and including 22kW)  Automatic measurement of the stator resistance  Programmable direct current braking  Integrated brake chopper for 4 quadrant drive  Four separate online switchable parameter sets

NORDAC SK 700E Operating Manual

1.4 Safety and installation information

NORDAC SK 700E frequency inverters are equipment for use in industrial high voltage systems and are operated at voltages

that could lead to severe injuries or death if they are touched.

 Installation and other work may only be carried out by qualified electricians and when the device is

disconnected. The manual must always be available for these persons and must be complied with.

 Local regulations for the installation of electrical equipment as well as for accident prevention must be

complied with.

 The equipment continues to carry hazardous voltages for up to 5 minutes after being switched off at the

mains. The equipment may only be opened or the cover or control element removed 5 minutes after the equipment has been disconnected from the power supply. All covers must be put back in place before the line voltage is switched back on again.

 Even during motor standstill (e.g. caused by a release block, blocked drive or output terminal short circuit), the

line connection terminals, motor terminals and braking resistor terminals may still conduct hazardous voltages. A motor standstill is not identical to galvanic isolation from the mains.

 Attention, even parts of the control card and, in particular, the connection plug for the removable technology

units can conduct hazardous voltages. The control terminals are mains voltage free.

 Warning, under certain settings the frequency inverter can start automatically after the mains are switched on.

 The circuit boards contain highly-sensitive MOS semiconductor components that are particularly sensitive to

static electricity. Avoid touching circuit tracks and components with the hand or metallic objects. Only the terminal strip screws may be touched with insulated screwdrivers when connecting the cables.

 The frequency inverter is only intended for permanent connection and may not be operated without effective

earthing connections that comply with local regulations for large leak currents (> 3.5mA). VDE 0160 requires the installation of a second earthing conductor or an earthing conductor cross-section of at least 10 mm2.

 Normal FI-circuit breakers are not suitable as the sole protection in three-phase frequency inverters when

local regulations do not permit a possible DC proportion in the fault current. The standard FI circuit breaker must comply with the new design as per VDE 0664.

 The inverter must be mounted in a switch cabinet that is suitable for its immediate surroundings. In particular it

must be protected from excess humidity, corrosive gases and dirt.

 In normal use, NORDAC SK 700E frequency inverters are maintenance free. The cooling surfaces must be

regularly cleaned with compressed air if the ambient air is dusty.

ATTENTION! DANGER TO LIFE!

The power unit can continue to carry voltages for up to 5 minutes after being switched off at the mains.

Inverter terminals, motor cables and motor terminals may carry voltage!

Touching open or free terminals, cables and equipment components can lead to severe injury or death!

6 Subject to technical alterations BU 0700 GB-1411

2 Assembly and installation

2.1 Installation

NORDAC SK 700E frequency inverters are available in various sizes depending on the output. When installed in a control cabinet, the size, power dissipation and perm. ambient temperature must be taken into account to prevent device failures.

The equipment requires sufficient ventilation to protect against overheating. Reference values apply here for the spaces above and below the frequency inverter within the control cabinet.

(up to and inc. 22kW, above > 100mm, below > 100mm and from and inc. 30kW above > 200mm, below > 200mm)

Electrical components (e.g. cable ducts, contactors, etc.) can be located within these limits. There is a height-dependent minimum separation distance from the frequency inverter for these components. This distance must be a minimum 2/3 of the object height. (Example: cable duct 60mm high 2/3 60mm = 40mm gap)

Additional side gaps for devices up to and inc. 55kW are not required. Mounting can be immediately next to each other. The

installation position is normally vertical. It must be ensured that the cooling ribs on the rear of the device are covered with a flat

surface to provide good convection.

Warm air must be vented above the device!

If several inverters are arranged above each other, ensure that the upper air entry temperature limit is not exceeded. (See also Chapter 7, Technical data). If this is the case, it is recommended that an "obstacle" (e.g. a cable duct) is mounted between the inverters so that the direct air flow (rising warm air) is impeded.

2.3 UB line filter up to 22kW (accessory)

An additional external line filter can be installed into the line supply of the frequency inverter to maintain the increased noise suppression level (class B as per EN 55011).

When connecting the line filter, comply with Chapter 2.9 "Wiring guidelines" and 8.3 "EMC". In particular, ensure that the pulse frequency is set to the default value (P504 = 4/6kHz) and that the maximum motor cable length (30m) is not exceeded and a shielded motor cable is used.

Mains connection is by means of screw connections at the lower end of the filter. Inverter connection is by means of a fixed cable of a suitable length (235-385mm).

The filter should be located as close as possible to the inverter; it can be used as a substructure or Book Size component.

2.4 Chassis line filter (accessory)

In contrast to the line filter described in Chapter 2.3, the HLD 110 (up to 110kW) has a UL acceptance for the North American market.

The interference noise suppression level of class A is achieved with up to a maximum motor cable length of 50m, and class B with motor cables of up to 25m.

When connecting the line filter, comply with Chapter 2.9 "Wiring guidelines" and 8.3 "EMC". In particular, ensure that the pulse frequency is set to the default value (P504 = 4/6kHz). The line filter should be placed as close to the side of the inverter as possible.

The connection is by means of screw connections on the upper (mains) and lower (inverter) ends of the filter

2.5 Line choke (accessories)

To reduce input side current harmonics, additional inductivity can be installed into the line supply to the inverter.

These chokes are specified for a maximum supply voltage of 480V at 50/60 Hz.

The protection class of the chokes is IP00 and they must therefore be installed in a control cabinet.

For frequency inverters with an output of 45 kW or more, a line choke is recommended where several devices are being used, in order to avoid possible adverse effects of one device on another. In addition, the charging currents (mains voltage fluctuations) are significantly reduced.

2.6 Output choke (accessories)

To reduce interference signals from the motor cable or to compensate for cable capacitance in long motor cables, an additional output choke can be installed into the inverter output.

Take care during installation that the pulse frequency of the frequency inverter is set to 3-6kHz (P504 = 3-6).

These chokes are specified for a maximum supply voltage of 460V at 0-100 Hz.

An output choke should be fitted for cable lengths over 150m/50m (unshielded/shielded). Further details can be found in Chapter 2.10.4 "Motor cable".

The protection class of the chokes is IP00 and they must therefore be installed in a control cabinet.

2.7 UB brake resistors (accessory)

During dynamic braking (frequency reduction) of a three phase motor, electrical energy is returned to the frequency inverter. In order to avoid overcurrent cut-off of the frequency inverter, the integrated brake chopper can convert the returned energy into heat by connecting an external brake resistor.

For inverter outputs up to 7.5 kW, a standard substructure resistor can be fitted; it can also be optionally equipped with a heat monitor for additional thermal protection of the resistor.

This design is no longer possible with higher frequency inverter outputs. Instead, the chassis brake resistors (Chapter 2.8) can be used.

2.8 Chassis brake resistors (accessory)

During dynamic braking (frequency reduction) of a three phase motor, electrical energy is released and returned to the frequency inverter. To prevent a safety shut-down of the frequency inverter, the integrated brake chopper can be activated by the connection of an external brake resistor.

The returned energy is converted into heat, so avoiding a possible overvoltage. All chassis resistors are UL certified and are not subject to

restrictions in the North American market. Connection is with screw connectors that are designated +B, -

B (1.5-22kW) or BR, +ZW (30-160kW), and the safety leads. For overload protection, a thermal switch is located close to

a brake resistor. The switch is freely available via the screw connectors (2 x 4mm2). The switching capacity is limited to 250VAC/10A, 125VAC/15A and 30VDC/5A.

NORDAC SK 700E Operating Manual

Note

The control cables, line cables and motor cables must be laid separately. In no case should they be laid in the same protective pipes/installation ducts.

The test equipment for high voltage insulations must not be used on cables that are connected to the frequency inverter.

2.9 Wiring guidelines

The frequency inverter has been developed for use in an industrial environment. In this environment, high levels of electromagnetic interference can influence the frequency inverter. In general, correct installation ensures safe and problem-free operation. To meet the limit values of the EMC directives , the following instructions should be complied with.

(1) Ensure that all equipment in the cabinet is securely earthed using short earthing cables that have large cross-sections and

which are connected to a common earthing point or earthing bar. It is especially important that every control device connected to the frequency inverters (e.g. an automation device) is connected, using a short cable with large cross-section, to the same earthing point as the inverter itself. Flat conductors (e.g. metal clamps are preferable, as they have a lower impedance at high frequencies.

The PE lead of the motor controlled by the frequency inverter must be connected as directly as possible to the earth connection of the cooling element, together with the PE of the corresponding frequency inverter mains supply. The presence of a central earthing bar in the control cabinet and the grouping together of all PE conductors to this bar normally ensures safe operation. (See also Chapter 8.3/8.4 EMC guidelines)

(2) Where possible, shielded cables should be used for control loops. The shielding at the cable end should be carefully sealed

and it must be ensured that the wires are not laid over longer distances without shielding. The shields of analog setpoint cables should only be earthed on one side on the frequency inverter.

(3) The control cables should be installed as far as possible from power cables, using separate cable ducts, etc. Where cables

cross, an angle of 90° should be ensured as far as possible.

(4) Ensure that the contactors in the cabinet are interference protected, either by RC circuits in the case of AC contactors or by

free-wheeling diodes for DC contactors, for which the interference traps must be positioned on the contactor coils. Varistors for over-voltage limitation are also effective. This interference suppression is particularly important when the contactors are controlled by the relay in the frequency inverter.

(5) Shielded or protected cables should be used for load connections and the shielding/protection should be earthed at both

ends, if possible directly to the frequency inverter PE/shield angle.

(6) If the drive is to be used in an area sensitive to electromagnetic interference, then the use of noise suppression filters is

recommended to limit the cable-dependent and radiated interference from the inverter. In this case, the filter must be mounted as closely as possible to the frequency inverter and fully earthed.

It is also an advantage if the inverter is installed together with the line filter in an EMC-proof enclosure, with EMC-compliant cabling. (See also Chapter 8.3/8.4 EMC)

(7) Select the lowest possible switching frequency. This will reduce the intensity of the electromagnetic interference produced by

the frequency inverter.

The safety regulations must be complied with under all circumstances when installing the

frequency inverter!

16 Subject to technical alterations BU 0700 GB-1411

2 Assembly and installation

WARNING

THESE DEVICES MUST BE EARTHED. Safe operation of the devices presupposes that qualified personnel mount and operate it in compliance with

the instructions provided in these operating instructions. In particular, the general and regional mounting and safety regulations for work on high voltage systems

(e.g. VDE) must be complied with as must the regulations concerning professional use of tools and the use of personal protection equipment.

Dangerous voltages can be present at the line input and the motor connection terminals even when the inverter is switched off. Always use insulated screwdrivers on these terminal fields.

Ensure that the input voltage source is not live before setting up or changing connections to the unit. Make sure that the inverter and motor have the correct supply voltage set.

2.10 Electrical connections

2.10.1 Line and motor connections

Note: If synchronising devices are connected or several motors are switched in parallel, the frequency inverter must be

operated with linear voltage/frequency characteristic curves, P211 = 0 and P212 = 0.

The line, motor, brake resistor and control connections are located on the base of the device. To gain access to the terminals, the device covers (cover and grid) must be removed. The connection terminals are now accessible from the front. All covers must be put back in place before switching on the supply voltage!

In general, the line, motor and brake resistor cables are connected first as their terminals are located on the bottom circuit board. The cable inlet is a slit opening on the base of the device.

Note: when using specific wiring sleeves, the maximum connection cross-section can be reduced.

Pay attention to the following:

1. Ensure that the voltage source provides the correct voltage and is suitable for the current required (see Chapter 7 Technical data). Ensure that suitable circuit breakers with the nominal current range are inserted between the voltage source and the inverter.

2. Connect the line voltage directly to the line terminals L1 - L2 - L3 and the earth (PE).

3. A four-core cable must be used to connect the motor. The cable must be connected to the motor terminals U - V - W and the PE.

4. If shielded cables are used, then the cable shield can also be applied to as much surface as possible on the shield support angle.

Note: The use of shielded cables is essential in order to maintain the specified radio interference suppression level. (See also Chapter 8.4 EMC limit value classes)

Technology Units (TU) are modules that can be inserted from above for display, parameterisation and control of the inverter.

WARNING

Modules should not be inserted or removed unless the device is free of voltage. The slots may only be used for the applicable modules. The slots are coded to prevent them being mixed up.

Extension Units (XU) are inserted into the slot at the base of the inverter. Such an extension unit is required if the speed is to be controlled or positioned by an incremental (absolute) encoder.

Customer Units (CU) are modules inserted inside the inverter in the upper recess. They are used for control and communication using digital/analog signals or bus interfaces.

3 Operation and display

The NORDAC SK 700E basic device is supplied with a blanking cover for the technology unit slot and the basic version has no components for parameterisation or control.

Technology units, customer units and special extension units

Through the combination of modules for the display, technology units and modules with digital and analog inputs, as well as interfaces, customer units or special extension units, the NORDAC SK 700E can be easily adapted to the requirements of various applications.

Controlling the frequency inverter with the ParameterBox

The frequency inverter can only be completely controlled via the ParameterBox if the parameter >Interface< (P509) is set to the >Keyboard< function (0 or 1) (the factory setting of the NORDAC SK 700E) and the inverter is not enabled via the control terminal.

Note: If the inverter is enabled in this mode, then the parameter set to be used can be selected for this inverter in the

menu: >Parameterisation< ...>Basic Parameter< in the parameter >Parameter Set<. If the parameter set has to be changed during operation, then the new parameter set must be selected in this

parameter and activated using the keys.

Attention: After the START command, the inverter can start immediately or with a pre-programmed frequency (minimum

frequency P104 or jog frequency P113).

Parameterising with the ParameterBox

The parameter mode accessed is the one selected at menu item >Parameterisation< at Level 1 of the Parameter Box. The parameter level of the connected inverter is accessed using the ENTER key.
